09:10 - 09:20 #18096 - OP028 Overlooked emergency – burnout syndrome among the emergency department staff.
OP028 Overlooked emergency – burnout syndrome among the emergency department staff.

Introduction: Examination of the burnout syndrome in various healthcare fields is of paramount importance for better understanding of the disorder as well as for the establishment of a suitable preventive and intervention program. The emergency departments’ employees are a risk group among healthcare workers, so it is our objective to further expand the knowledge on the characteristics of the burnout syndrome among the Hungarian emergency department staff. Aim of this study is to examine the burnout syndrome and its associations with different variables among the workers of the Department of Emergency Medicine at the University of Szeged moreover to develop and finetune a prevention and intervention training for the medical staff to help coping with everyday stress as well as rise awareness to burnout symptoms.

Method: Cross-sectioned design utilizing a self-administrated questionnaire was used to collect data from the staff (n=72). Burnout was measured using the Maslach Burnout Inventory, while psychological immune competence was measured using the Psychological Immune Competence Questionnaire. Upon data collection a three-round training was developed and implemented after which the measurement of burnout was repeated using the same test battery. We tested the interaction between different variables (age, number of children, years spent in healthcare, weekly number of working hours, number of somatic symptoms, social support and psychological immune competence) and burnout subscales (emotional exhaustion, depersonalization and personal accomplishment) using Pearson correlation. Independent samples t-test was used to compare burnout subscale means in different marital status groups, while Mann-Whitney U-test to compare burnout values between genders. Lastly, the data of the retest was compared using paired sample t-test.  

Results: We found burnout syndrome to be considerably prevalent among the workers especially nurses and physicians (compared to other staff: medical orderlies, medical clerks). Moderate emotional exhaustion was reported both among doctors and the nursing staff. While physicians reported moderate depersonalization, lower personal accomplishment was measured among the nurses. In both, original and post-training study we found a significant correlation between burnout and age, number of children, number of years in healthcare system, number of physical symptoms, social support and psychological immune system. There was no difference between genders, while the workers who were in a relationship reported significantly lower depersonalization. Due to personnel fluctuation we were able to retest only 54% of the original sample, with no change in burnout results. Nonetheless, the data shows the need for individual burnout intervention which presents in significantly stronger relationship with the psychologist as well as in frequency of contact with the psychologist.

Conclusions: The results obtained show correlations and reveal protective and risk factors in burnout which can be key to establishing a preventive and intervention strategies. The training on burnout syndrome rose awareness among the departments’ staff, while personal one to one interventions helped the workers develop individual coping strategies. This data allows us to further develop new institutional intervention techniques. Ethical approval was given by the Ethics Committee of the University of Szeged, with the license number: 122/2017-SZTE (4035).

09:20 - 09:30 #18857 - OP029 Assessed and discharged – short-term emergency department visits.
OP029 Assessed and discharged – short-term emergency department visits.

Background

Emergency departments (EDs) play a vital role in the healthcare system either as the freely accessible primary entry point for healthcare or as secondary healthcare referred to by primary healthcare services. Recently, EDs have experienced an increased number of patients including to a greater extent elderly patients with more comorbidity. In addition, some EDs also face decreased available resources (e.g. fewer beds) and crowding in the EDs is now a reality in many countries. It is unclear how these changes affect the ED patient population. We chose to focus on the contribution of short-term ED visits to the ED population and outcome following these contacts.

Aim

Thus, our aim was to investigate 1) the proportion of short-term ED visits (5 hours or less) & 2) the characteristics, diagnoses, patterns of renewed contacts and mortality of patients with short-term ED visits.

Method

Observational cohort study of patients in the emergency departments at three sites in the North Denmark Region 2014-2016. Patients with a valid personal identification number were included. Short-term ED visits defined as 5 hours or less. Primary outcomes were ICD-10 diagnosis chapter, 1- and 30-day mortality and readmissions on days 1 and 2. Data was retrieved from the Patient Administrative System and the Danish Civil Registration System. Descriptive statistical analyses and Kaplan-Meier mortality estimates were performed.   

Results

During 2014-2016, there were 280 365 contacts to the EDs in the North Denmark Region. Of these, we included 134 362 ED visits with duration of 5 hours or less (47.9%). Mean age was 32 (IQR: 16-57), 48.6% were female.

Top five ICD-10 chapters were injury and poisoning N=80 862 (60.2%), other factors N=19 725 (14.5%), symptoms and signs N=15 568 (11.6%), musculoskeletal disease N=3 643 (2.7%) and respiratory disease N=2 413 (1.8%). Overall mortality was 1-day: 0.30% (0.27-0.33), 30-day: 0.74% (0.70-0.79), with the highest mortality among circulatory diseases: 1-day: 10.67% (9.38-12.12) 30-day: 11.94% (10.59-13.46).

Number of renewed contacts on days 1 and 2 after discharge were N=4 696 (3.5%) and N=1 652 (1.2%). ICD-10 chapter from the initial contact for patients with renewed contact on day 1: other factors N=2 522 (53.7%), injury and poisoning N=1 587 (33.8%) and symptoms and signs N=223 (4.8%) and on day 2: injury and poisoning N=951 (57.8%), other factors N=258 (15.6%) and symptoms and signs N=172 (10.4%). Overall mortality for patients with renewed contacts on day 1 or 2 was: 1-day 0.02% (0.00-0.11) and 30-day: 0.43% (0.29-0.62).

 

Discussion and conclusion

Almost half of all ED contacts were short-term visits and predominately due to injuries, which explains the young mean age and low overall mortality. Non-specific diagnoses was the second largest group of patients. Overall, only few patients had a renewed contact within 1 or 2 days. Nevertheless, patients who received non-specific diagnoses during the first admission comprised the largest group of readmitted patients on day 1.

Further research on the non-injury group of patients is needed, in particular the non-specific diagnoses.

09:30 - 09:40 #18354 - OP030 Applying lean methodology in the emergency department: reducing inappropriate high-sensitivity cardiac troponin I testing in patients complaining of chest pain.
OP030 Applying lean methodology in the emergency department: reducing inappropriate high-sensitivity cardiac troponin I testing in patients complaining of chest pain.

Background: chest pain is the reason for emergency department (ED) admission in 5-9% of cases. Cardiac origin has been reported in up to 45% of ED admission for chest pain. In our ED there are several predefined panels of laboratory tests that allow to improve and speed up the diagnostic process based on the prevalent symptomatology shown by the patient (for example: chest pain, abdominal pain, sepsis). In our ED we observed an increasing number of high-sensitivity cardiac troponin I (hsTnI) tests in patients complaining of chest pain. We thought that the main reason for this increase was the presence of hsTnI in the predefined chest pain test panel; furthermore, said panel didn’t differentiate between typical and atypical chest pain. The ideal management of patients experiencing chest pain includes not only avoiding misdiagnosis, but also avoiding unnecessary lab tests and therefore inappropriate hospitalizations. Based on lean methodology applied to emergency medicine, in order to further increase the quality and safety of patient care by reducing inappropriate testing, from June 2017 we decided to remove hsTnI from the predefined chest pain test panel.

Methods: we decided to conduct a retrospective, observational, monocentric study with the primary outcome of verifying whether removing hsTnI from the chest pain test panel had led to a reduction in its dosage requests over a six-month period (June-December 2018), compared to June-December 2016 in which hsTnI still appeared in the chest pain test panel. In these two periods of time we first considered the total number of patients admitted to our ED and then those who had admission and discharge diagnoses, according to the International Classification of Diseases, Tenth Edition (ICD-10), compatible with presentation of chest pain; we also considered patients with ICD-10 diagnoses not related to chest pain presentation in which hsTnI testing was requested.

Results: from June to December 2016 ED admissions were 29441 and hsTnI dosage was requested 7021 times (mean value 0.24), in the same six-months period of 2018 admissions were 30182 with 5160 hsTnI dosage requests (mean value 0.17). In 2016 and in the same six-month period cited above, patients with ICD-10 diagnosis compatible with presentation of chest pain were 1728 with 2089 hsTnI dosage requests (mean value 2.21, considering multiple tests in the same patient); in 2018 out of 1697 patients only 1752 HsTnI were requested (mean value 1.03). The same can be seen in patients with ICD-10 diagnosis not related to chest pain presentation: in 2016 out of 26307 admission hsTnI dosage was requested 4932 times (mean value 0.19), in 2018 out of 27034 admissions, hsTnI dosage was requested 3408 times (mean value 0.13).

Discussion and conclusion: the removal of hsTnI from the predefined chest pain test panel led to a decrease of inappropriate hsTnI dosage requests without causing missed diagnoses of acute coronary syndrome (ACS). Applying this kind of methodology probably forced ED physicians to better evaluate chest pain characteristics, EKG findings and patient medical history.

09:40 - 09:50 #18628 - OP031 A validation of the National Emergency Department Overcrowding Score (NEDOCS) in a UK non-specialist emergency department: a prospective observational study.
OP031 A validation of the National Emergency Department Overcrowding Score (NEDOCS) in a UK non-specialist emergency department: a prospective observational study.

Introduction 

Crowding in the Emergency Department (ED) is recognised as a significant problem linked with various adverse health outcomes.  However, there is no widely accepted measurement tool to enable clinicians to better understand and manage ED crowding, though several have been proposed including from the US the NEDOCS score.

 

Objectives

This study aimed to externally validate NEDOCS in a UK ED setting against expert clinician opinion, and to assess inter-rater reliability between nurse and consultant physician opinions.

 

Methods

This prospective single-centre study sampled data in real-time over four time periods during 2018 in a non-specialist hospital ED in the south of England to calculate NEDOCS values.  The outcome variable was clinician opinion of crowding using a six point Likert-scale for both consultant-in-charge and nurse-in-charge. Paired results were averaged to give a combined score, and dichotomised to construct AUROCs and diagnostic testing for a range of NEDOCS cut-offs.  The same method was also used to assess the association of scores with clinician opinion of risk of patient harm, safety, and adequacy of staffing levels. To adjust for the effect of temporal correlation (7), further analysis was conducted on observations sampled every six hours, offset by 2 hours for each sequential day to allow analysis of variability between and within days.

 

Results

From 905 sampled hour intervals, 448 complete data points (both clinician opinions of crowding) were obtained.  The ED was crowded 18.53% according to the composite opinion. Median NEDOCS score was 63 (IQR 43 to 85). Weighted kappa score evaluating inter-rater agreement of nurse and consultant opinion was moderate at 0.57 (95% CI: 0.56 to 0.60). AUROC for NEDOCS to predict clinical opinion of crowding was 0.81 (95% CI 0.77 to 0.86)  

For 6-hour sampling there were 157 complete observations. Adjusted for temporal correlation in this manner, AUROC was 0.80 (95% CI 0.73 to 0.88).  

For predicting clinician opinion of risk of harm and safety, AUROCs were 0.71 (95% CI 0.61 to 0.82) and 0.71 (95% CI 0.63 to 0.80) respectively. Higher scores of NEDOCS also correlated with a clinician opinion of insufficient staffing; AUROC was 0.70 (95% CI 0.64 to 0.76).

Optimal performance in our ED was a NEDOCS of >85 with a sensitivity of 59.0% (95% CI 47.7 to 69.7) and a specificity of 82.7% (95% CI 78.5 to 86.5).

Conclusions 

NEDOCS demonstrated good discriminatory power for crowding in our ED.  It also correlated with perception of safety, adequacy of staffing and risk of patient harm.  However further refinement of the score is needed, including the impact of triaged patient acuity-level, which was not incorporated in the original score.  Determining ED specific cut-off point(s) for the score is important, as the previously published thresholds for crowding may not be suitable for all EDs.  This study has demonstrated the feasibility of electronic capture in real time in a UK ED.

OP032 An external validation of the full International Crowding Measure for the Emergency Department (ICMED) in a UK non-specialist emergency department: a prospective observational study.

Introduction 

Crowding in the Emergency Department (ED) is recognised as a significant problem linked with various adverse health outcomes.  However, there is no widely accepted measurement tool to enable clinicians to better understand and manage ED crowding, though several have been proposed including the recently derived ICMED. 

 

Objectives

This study aimed to externally validate ICMED in a different UK ED setting to the derivation studies.  Additionally the study aimed to evaluate whether using the full form of ICMED improved the score’s diagnostic ability. 

 

Methods

This prospective single-centre study sampled data in real-time over four time periods during 2018 in a UK non-specialist hospital ED to calculate ICMED values, including calculation of proportion of patients leaving the ED without being seen, the measure omitted from other studies. The outcome variable was clinician opinion of crowding using a six point Likert-scale for both consultant-in-charge and nurse-in-charge. Paired results were averaged to give a combined score, and dichotomised to construct AUROCs and diagnostic testing for a range of ICMED cut-offs.  Association of scores with clinician opinion of risk of patient harm, safety, and adequacy of staffing levels was also assessed.  To adjust for the effect of temporal correlation, further analysis was conducted on observations sampled every six hours, offset by 2 hours for each sequential day to allow analysis of variability between and within days.

 

Results

From 905 sampled hour intervals, 448 complete data points (both clinician opinions of crowding) were obtained.  The ED was crowded for 18.5% according to the composite opinion. Median ICMED score was 2 (IQR 2 to 3).  AUROC for ICMED to predict clinical opinion of crowding was 0.64 (95% CI 0.58 to 0.70). For predicting clinician opinion of risk of harm and safety, AUROCs were0.60 (95% CI 0.50 to0.70) and 0.59 (95% CI 0.49 to 0.69) respectively. Higher scores of ICMED also correlated moderately with a clinician opinion of insufficient staffing; AUROC was 0.58 (95% CI 0.52 to 0.65)

Optimal performance in our ED was an ICMED of >3 with a sensitivity of 49.4% (38.2 to 60.6) and a specificity of 74.3% (69.4 to 78.7).

For 6-hour sampling there were 157 complete observations. Adjusted for temporal correlation in this manner, AUROC was 0.69 (95% CI 0.59 to 0.79).  However, for ICMED adjustment for temporal correlation required a total of 208 complete observations and 30 crowded observation intervals for adequate power.

  

Conclusions 

This is the first study to validate the full form of the ICMED score.  ICMED demonstrated moderate discriminatory power for crowding (in line with previously published values) as well moderate discrimination for perception of safety, adequacy of staffing and risk of patient harm in our ED.  When adjusted for temporal correlation the AUROC showed a trend towards improvement.  However, the sample size was inadequate to fully account for the effect of temporal correlation.   Further data capture is currently underway to address this.  This study has demonstrated the feasibility of electronic capture of all the parameters of the ICMED score in real time in a UK ED.

10:00 - 10:10 #18756 - OP033 Retrospective analysis of complaints in emergency department: a quality indicator?
OP033 Retrospective analysis of complaints in emergency department: a quality indicator?

Background:

Emergency department patient complaints are often justified and may lead to apology, remedial action or compensation. The aim of the present study was to analyze emergency department patient complaints in order to identify procedures or practices that require change and to make recommendations for intervention strategies aimed at decreasing complaint rates.

Methods:

We undertook a retrospective analysis of patient complaints from a tertiary hospital emergency department from 2010 to 2018. Data were obtained from letters of response to patient’s complaints. Ethics committee of the Erasme hospital approved the study and waived informed consent.

Results:

349,714 patients were seen in the emergency room from 2010 to 2018, of whom 74,944 (21.4%) were hospitalized. In addition to this number, there are 18,206 patients (5.2%) who leave the emergency department without being seen due to department overcrowding. 279 written complaints (0.08%) were sent to the medical management of the hospital, the mediation service or directly to the emergency department. The median age of patients associated with a complaint was 33 (18-53, IQR; 0 to 80, range) years, with M:F ratio = 0.47. Among the complaints 23.5 % concerned the diagnosis, 22 % invoices for hospital care, 18 % communication with the medical doctor, 16 % the length of the waiting time, 10.5 % the treatment itself, and 10 % the nurse’s communication.

Discussion & conclusions:

Over the observation period, the yearly number of written complaints remained stable at less than 0.1 % of total number of the ED’s patients. More than 50 % of the complaints concerned a wrong or inadequate diagnosis, invoice for hospital care, and communication with the medical doctor. As a remedial measure, meticulous patient care and communication skills workshops for emergency department doctors and nurses will improve patient’s satisfaction and quality of care in the ED.

10:10 - 10:20 #18903 - OP034 Performing blood samples during Triage evaluation can improve overcrowding in ED: a Propensity-Score-Weighted Population-Based Study.
OP034 Performing blood samples during Triage evaluation can improve overcrowding in ED: a Propensity-Score-Weighted Population-Based Study.

BACKGROUND: the length of stay (LOS) in the Emergency Department (ED) is one of the causes of the overcrowding condition that currently affects most European EDs. As demonstrated in the literature, the LOS of ED patients is increasing and will increase in the coming years. A longer LOS leads to more significant crowding, poorer functioning of emergency services, increased risk of mortality and exponential cost increases. The heterogeneous morbid conditions combined with the increasing comorbidities presented by patients, force an in-depth diagnostic in many cases. It has been proved that 2/3 of patients accessing ED need an instrumental assessment and 1/3 need blood analysis. The patient's diagnostic path strongly influences the LOS.

OBJECTIVES: to verify whether sending blood samples during the triage process can decrease the LOS and the duration of the medical examination in patients with green and yellow code according to the Manchester Triage System (MTS).

METHODS: a retrospective observational study was performed from January 2018 to January 2019. All patients with a minor code (green and yellow) who needed blood sample for further diagnosis were considered. Patients who performed blood sampling during the TRIAGE evaluation were compared with those who performed blood sampling during the medical visit. Moreover, we calculated and compared the LOS and the time between the start of the medical evaluation and discharge of the two groups of patients. The anamnesis, clinical and severity characteristics documented at the time of triage were recorded.

RESULT: during the study period, 15.596 patients were enrolled. LOS was lower in the group of patients with triage blood sampling with a median of 154 minutes (100 - 231) compared to 172 (119 - 246) in the control group (p< 0.001). Overall, the triage blood sampling group was older, with greater comorbidity and with a more severe clinical condition. A propensity score matching was performed to obtain two homogeneous groups. After statistical matching, LOS remained lower in the triage-sampling group of patients (151 versus 175 minutes, p<0.001). In the adjusted multivariate model, the triage blood sample was found to be an independent factor of decrease of the LOS with standardized coefficients β = 0.857 (0.822 – 0.894, p<0.001). After propensity score matching, we also evaluated the duration of the triage, obtaining an equality of triage times both if the blood sample was taken in triage or during the medical examination, the total duration of the triage lasted 4 minutes.

CONCLUSION the execution of blood samples by the triage nurse reduces the LOS of non-urgent patients in ED and significantly reduces the duration of the medical examination.

10:20 - 10:30 #19039 - OP035 Economic value of a clinical pharmacist at the Emergency Department: a retrospective observational study.
OP035 Economic value of a clinical pharmacist at the Emergency Department: a retrospective observational study.

Background. Medication errors (MEs) and other drug related problems (DRPs) are common issues on hospital admission. These MEs and DRPs can cause preventable adverse drug events (pADEs) resulting in patient harm with a significant additional cost. A clinical pharmacist (CP) dedicated to the Emergency Department (ED) can improve medication safety by performing medication reconciliation and review, and hence avoid additional costs.

Objective. The aim of this study was to determine the economic value and the cost-benefit of a CP in the ED by applying a theoretical model (University of Sheffield School of Health and Related Research – SCHARR1).

Setting and Methods. This retrospective, single-centre, observational study was carried out in the ED of a tertiary care university hospital. Since October 2016, 1 FTE CP is dedicated to the ED. Patient-specific recommendations recorded by the CP during a 1 month period were observed. On admission to the ED, the CP had carried out a standardized medication reconciliation and medication review in order to determine pADEs. The most important pADE for each patient was selected and classified for its potential to cause harm using severity rating methods. An expert panel of senior ED physicians evaluated the pADEs for clinical significance. The net cost avoidance was calculated according to the SCHARR model1. We took into account the lower cost limit of the SCHARR model and current inflation. Statistical analysis was done using Graphpad Prism® and Microsoft Excel®.

Results. During 1 month (18 weekdays), the CP recorded recommendations for 136 patients (>18 years) admitted to the ED. On ED admission, medication reconciliation was performed for 98 patients with a median of 4 (IQR 2-7) discrepancies/patient. A medication review for both chronic medication and medication prescribed at hospital admission was performed (n=109 and n=98 respectively). Only the CP’ interventions leading to the most important pADE for each patient were taken into account for the calculation of the cost avoidance. We classified 18 (14.8%) DRPs, 66 (54.1%) DRPs, 37 (30.3%) DRPs and 1 (0.8%) DRP as a pADE with minor or no harm, significant pADE, serious pADE and at least as a severe, life-threatening or fatal pADE, respectively. According to the SCHARR model, this contributed to a net cost avoidance of €40 940. We documented 5 (4.1%) discrepancies without DRP, 53 (43.4%) discrepancies linked to a DRP and 64 (52.5%) DRPs without discrepancy with a cost avoidance of respectively €303, €17 734 and €31 003. The benefit:cost ratio was 5.05:1. Furthermore, the pharmacist carried out a total of 722 interventions.

Conclusion. A CP, integrated in a multidisciplinary ED team, has an important economic value. Furthermore, the CP enhances medication quality and safety by preventing discrepancies in the chronic medication and by the identification of DRPs on admission at the ED.

OP036 Utility of a Regional Poison Center in Care of Patients Seen at Emergency Departments.

Background:  Poison control centers (PCs) are an essential component of the healthcare system and providing clinical management and improving patient outcomes in cases of toxic exposures. PCs have also demonstrated utility in decreasing the healthcare costs by reducing the use of emergency medical services and length of stay in hospitals. Apart from the clinical expertise, PCs also provide valuable information regarding drugs including medication identification, dosage, interactions, storage, and disposal. This study analyzed the trends in exposure calls received by the PCs from emergency departments (EDs).  

Methods: The case management software, Toxicall, was queried for human exposure calls from EDs between 2016 and 2018. We descriptively assessed the relevant demographic characteristics. Trends in call frequencies and rates (per 100,000) were analyzed using Poisson regression methods. Percent changes from the first year of the study (2016) were reported with the corresponding 95% confidence intervals (95% CI).

Results: The regional poison center serves over 2.4 million people and 45 hospitals within Southwest Virginia, with the specialists handling an average of 58,000 calls every year. Between 2016 and 2018, there were 9,767 calls that were received from the EDs, with 74% of these reporting an acute exposure to a toxic substance. Most exposures occurred at the patients’ residence (87.2%). Females (54%) were predominant in this sample. Among the cases, 23.1% were children under 6 years of age while 8.2% were individuals above 60 years of age. Unintentional reasons accounted for 47.9% cases, while suspected suicides were responsible for 36.2% calls. Ingestion (77.6%) was the most common route of exposure followed by inhalation (7.2%). Unintentional reasons accounted for majority of cases under 6 years of age, while intentional reasons caused 83% of teenage exposures. Intentional exposures were more common among the adult age groups. Serious adverse events were uncommon in our sample, with 10% cases exhibiting major clinical outcomes and only 10 fealties reported in the 3 year study period. Neurological (28.9%) and cardiovascular (19.4%) effects were most pronounced. Approximately one-fourth of the patients were admitted to the psychiatric facility. Exposures to pharmaceuticals like acetaminophen (7.6%) were frequent. Exposures to alcoholic beverages (8%) were also common. Fluids and IV were used as a therapy in 40% cases. While the frequency of calls received by the PC from EDs decreased from 3,461 in 2016 to 3,302 in 2018, the rate of such calls per 1,000 calls received by the PC increased significantly by 5.7% (95% CI: 2.3%, 8.7%, p<0.011) from 169.9 to 179.6 during the study period.     

Conclusions:  Rate of calls received by the PC from EDs during the study period increased. The PCs, a reliable source of information, are being increasingly utilized for the management of complex poisoning cases. PCs provide the EDs with immediate access to the experts who can help in the diagnosis, management, and treatment of toxic exposures and drug overdoses. This triage of cases ensures an optimal level of care leading to reductions in hospitalizations and improving the quality of healthcare.

SP021 Left holding the baby: reasons and outcomes of neonatal emergency department attendance, a 2-year retrospective observational study in a UK tertiary hospital.

Background and Objective

Neonates attending the paediatric emergency department (ED) pose challenges. The presenting problems differ from older children and are unique to this age group, prescribing requires attention to detail and consideration of physiological quirks and even resuscitation algorithms are irritatingly idiosyncratic. So who are these babies that are brought to the ED by their parents, what serious illness needs consideration and why are they attending the ED in the first place? We present a large data set with a view of identifying attendance patterns, population characteristics and potential pathway issues.

Methods

Retrospective review of all neonatal attendances (age less than 28 days) to the paediatric ED of a UK tertiary hospital during a two year period (01/04/2017 to 31/03/2019) from the electronic patient record database for age at presentation, presenting complaint, source of referral, length of stay in ED and disposal. Where necessary, individual records were accessed and any missing information added. Acuity of visits was determined by the need for admission, duration of in-patient stay and follow-up arrangements. 

Results 

1,699 attendances involving 1,467 neonates were identified, constituting 3.81% of all paediatric ED attendances (n=44,571) and 16.2% of all births in the hospital (n=10,515). The peak of attendance occurred at age 2-3 days, with over 60% presenting with jaundice. Monthly attendance mirrored the birth rate, there was no seasonal variation. The most common presenting problems were jaundice, respiratory symptoms, weight-loss and vomiting. Only 23.7% of all visits were self-referred. Most referrals came from midwifes (37.3%), other primary healthcare professionals (24.1%) and after contacting the UK’s 111 helpline (9.83%). 5.1% of babies came by emergency ambulance. As expected, the ratio of acute to non-acute visits was higher in referrals by ambulance (r=1.00) and primary healthcare professionals (r=0.808) compared to self-referrals (r=0.728) but not significantly so. On average, these infants spent 165 minutes in the ED. There were 111 breaches of the 4-hour target (6.42%). The admission rate was 42.1%, and the top reasons for hospital admissions were jaundice (44.3%), feeding problems (18.2%), respiratory (11.3%) and infection including suspected sepsis (7.97%). 32.9% of neonates admitted were discharged within 48 hours of admission. 4 deaths including two neonatal sepsis deaths were identified, both of which had disseminated Herpes-Simplex Virus (HSV) infection. 

Discussion

ED attendance is common during the neonatal period, notably over half of the visits are for non-acute complaints and do not require immediate medical intervention except parental reassurance.

The large number of jaundice-related attendances calls for a review of the jaundice care pathway. We will be discussing possible interventions that may help reduce unnecessary attendances in the ED like feeding support following postnatal discharge and improved awareness of neonatal normal variants by primary care professionals.

We suggest that the current referral algorithms for the UK's national telephone advice service 111 may significantly increase inappropriate ED attendances.

The neonatal deaths due to sepsis were both caused by HSV infection, our local incidence matching published evidence and we postulate Aciclovir to be first-line treatment in neonates presenting with sepsis to ED.

10:50 - 10:55 #18445 - SP022 Analysis of limited-sequence head computed tomography for children with ventriculo-peritoneal shunt: potential to reduce diagnostic radiation exposure.
SP022 Analysis of limited-sequence head computed tomography for children with ventriculo-peritoneal shunt: potential to reduce diagnostic radiation exposure.

Background and Objectives

Complications related to ventriculoperitoneal shunt (VPS) are common, and multiple revisions are almost expected throughout a patient's lifetime. Standard noncontrast head computed tomography (CT) that is currently the gold standard for diagnosis of VPS dysfunction, consists of an average of 35 to 40 sequences and causes severe radiation exposure. However, it is stated that the evaluation of four sequences which show 4 ventricles, 3 ventricles, lateral ventricles and basal ganglia may be sufficient for the diagnosis of VPS malfunction. This may significantly reduce the radiation exposure. The aim of this study was to determine the feasibility of the four-sequence limited head CT for predicting VPS malfunction.

Methods

We performed a retrospective analysis of the PED medical records (MRs) between January 2013 and December 2017 that involved all patients who received a head CT for suspected VPS malfunction. MRs were reviewed to describe demographic, clinical characteristics surgical interventions and full head CT reports. For all enrolled patients, a limited series was generated from the last CT scan by selecting four representative axial slices based on the sagittal scout image. Four slices selected at the level of the fourth, third ventricle, basal ganglia level, and lateral ventricles, respectively. A blinded neuroradiologist evaluated the limited 4- slice CT to determine the VPS malfunction. After this review, we compared the standard full head CT reports with the limited 4- slice CT, and analyzed the sensitivity and specificity of the 4- slice CT to predict VPS malfunction. We also calculated the real 4 –slice CT sensitivity and specificity for children  who received surgical shunt revision.

Results

A total of 164 patients were enrolled in the study. The mean age was 54 ± 24 months and 85 (52%) were males. The most common presentation complaints were vomiting (27%) and seizure (17%). V-P shunt revision was performed in 60 patients (37%) as a result of clinical and radiological evaluation. When we compared the standard complete head CT reports with the limited modality, the limited 4-slice CT had sensitivity, specificity 83% and 97% respectively, for the evaluation of the changes in ventricular size. However, when the analyze performed based on surgical V-P shunt revision, only one case would have been missed with the limited 4-slice CT. The  sensitivity was 98% and specificity 78%. The effective dose (ED50) of limited 4-slice head CT was 0.32 mSv, while the ED50 of the standard head CT was 2.7 mSv. In this way, the prefer of a limited head CT instead of a complete head CT may provide about 88% reduction in radiation dose.

Conclusion

The present study demonstrates that utilization of limited head CT scan in the evaluation of children with suspected VPS malfunction is a feasible strategy for the evaluation of the ventricular size as well as prediction of surgical intervention. Further prospective, well designed studies are needed to evaluate the reliability of limited head CT for the clinical evaluation of VPS malfunction.

10:55 - 11:00 #18534 - SP023 Assessment of rewarming methods in unplanned out-of-hospital births from a prospective cohort.
SP023 Assessment of rewarming methods in unplanned out-of-hospital births from a prospective cohort.

Background and Objectives: Mobile intensive care units frequently manage unplanned out-of-hospital births (UOHB). Rewarming methods during pre-hospital management of UOHB have not yet been compared. The aim was to compare rewarming methods used during pre-hospital management in a large prospective cohort of UOHB in France.

Methods: We analyzed UOHB from the prospective AIE cohort from 25 prehospital emergency medical services in France. The primary outcome was the change in body temperature from arrival at scene to arrival at hospital. Our database was approved by the French Data Protection Authority and by a French research ethics committee. Maternal consent was systematically requested before or during birth management (left at the physician’s discretion).

Results: From 2011 to 2018, 1,854 UOHB were recorded, of whom 520 were analyzed. We found that using incubator care was the most effective rewarming method (+0.8°C during transport; P < 0.001), followed by the combination of plastic bag, skin-to-skin and cap (+0.2°C). The associations plastic bag + cap and skin-to-skin + cap did not allow the newborn to be warmed up but rather to maintain initial temperature (+0.0°C). The results of the multivariate model were consistent with these observations, with better rewarming with the use of an incubator (Adjusted temperature difference = +0.33 95CI(0.13; 0.52)). According to the classification and regression tree (CART) method, we also identified circumstances of increased risk of hypothermia according to classification and regression tree, like premature birth (< 37 weeks of gestation) and/or low outside temperature (< 8.4°C).

Conclusions: Using an incubator was the most effective rewarming method during pre-hospital management of UOHB in our French prospective cohort. Based on our model, in cases of term less than 37 weeks of gestation or between 37 and 40 weeks with a low outside temperature, using such a method would be preferred.

11:00 - 11:05 #19167 - SP024 Clinical decision rules in cervical spine injury assessment: a prospective study in a paediatric trauma centre.
SP024 Clinical decision rules in cervical spine injury assessment: a prospective study in a paediatric trauma centre.

Background:

Paediatric cervical spine injury (CSI) is rare but can have devastating consequences. In an attempt to identify all children with CSI, many children are assessed for possible injury and may either be “clinically cleared” or receive imaging to exclude radiologically apparent injury. Clinical decision rules (CDRs), or proposed rules, are commonly used to guide imaging decisions despite limited evidence for their use in paediatric populations.

 

Objectives:

To determine the frequency of previously identified risk factors for CSI in children presenting to a single Australian centre and to assess the performance of commonly used CDRs or proposed rules when strictly applied to our population, including the projected impact on imaging rates if these CDRs were strictly applied.

 

Method:

Prospective observational study across one year of all children under 16 years presenting to Emergency Department (ED) with possible CSI as defined either immobilization for possible CSI, neck pain the context of trauma or otherwise considered at risk by the ED team. Those with imaging prior to arrival were examined as separate cohort. CDR variables for the National Emergency X-ray Utilization Study (NEXUS) rule, Canadian Cervical Spine Rule and proposed Paediatric Emergency Care Applied Research Network (PECARN) rule were collected prospectively and applied post hoc.

 

Results:

1010 children were enrolled; 973 had not received prior imaging. Of these 973, two thirds were male, median age was 10.9 years and 16% were aged under 5. 40.7% received imaging of their cervical spine with 32.4% receiving X- Rays, 13.4% Computed Tomography and 3% Magnetic resonance imaging. 5 children had CSI.  Nine children of the 37 with prior imaging had CSI.

 All 3 CDRs identified the 5 children with CSI who had not received prior imaging (Sens 100%, 95%CI 56-100). The NEXUS rule did not identify 2 out of the 9 children with prior imaging. 

If strictly applied as a rule for imaging, all 3 CDRs or proposed CDRs would increase imaging rates in our setting, with individual CDR guided rates ranging between 44 and 68%. Despite these higher projected imaging rates, and while all but 2 imaged children were positive for at least one of the three rules (i.e. imaging indicated according to the CDR), no single rule suggested that all children  imaged in current practice should actually be imaged; individual NEXUS and PECARN CDRs were  positive in 82 and 91% of those imaged respectively.

 Conclusion:

Paediatric CSI is rare, and while many children are clinically cleared without imaging, a considerable percentage receive imaging for relatively few injuries detected. CDRs have been proposed to guide imaging decisions, however the use of those currently available to the paediatric practitioner, could, if strictly applied, result in more children receiving imaging than occurs in current practice. Research with a larger cohort is required to assess whether a more refined CDR can be designed to limit discomfort, cost and radiation exposure, and to formally determine the performance of current rules (including sensitivity in injury detection) in the paediatric setting.

10:45 - 10:50 #18014 - SP025 Effective Factors in Improving the Emergency Department Preparedness of Hospitals in Radiation and Nuclear Incidents and Nuclear Terrorism: A Systematic Review.
SP025 Effective Factors in Improving the Emergency Department Preparedness of Hospitals in Radiation and Nuclear Incidents and Nuclear Terrorism: A Systematic Review.

Background: Due to existence of nuclear power plant sites in various parts of the world, as well as political threats in disaster-prone areas throughout the world, there is a probability of nuclear and radiation incidents. The present study was carried out with the purpose to extract effective criteria in emergency department preparedness of hospitals in radiation, nuclear incidents and nuclear terrorism in different countries around the world.

Methods: A systematic search was carried out in Cochrane Library, PubMed, Scopus, Science Direct, Web of Science, ProQuest and EmBase databases between January 1970 to July 2018. The systematic search was carried out according to the PRISMA standard. The required information was extracted from the papers based on the abstract and collection form.

Results: After searching the databases, 1091 papers were finally extracted. The initial search included research papers. After reviewing the papers’ titles, abstracts and full texts, 15 papers were selected for final analysis. Next, 32 criteria were extracted. The criteria were divided into 3 categories. The categories included staff, stuff and systems (structure). The most frequent criteria included training criteria, personal protective equipment, decontamination and practice.

Discussion and Conclusion: The results of the systematic review provided an overview of the effective factors in improving the emergency department preparedness during radiation and nuclear incidents. In addition to the mentioned criteria in different studies, there are other hidden factors that affect the emergency department preparedness in radiation and nuclear incidents, thus, the highest level of preparedness should be considered.



Registration: The study protocol was first registered in PROSPERO database with the identification number CRD42018102815. Funding: This project has partly been supported by a grant from the Shiraz University of Medical Sciences with the code 97-01-07-17271. Ethical approval and informed consent: Informed consent was obtained from all individual participants included in the study.

10:50 - 10:55 #18157 - SP026 Medical assistance coordination of terrorist attack.
SP026 Medical assistance coordination of terrorist attack.

Introduction: In case of mass casualty incident (MCI) abroad, medical assistance companies are entrusted to provide a rapid and appropriate response. In addition to a standardized and regularly updated operating process, exercises are key component to ensure performance. The purpose of the present report was to evaluate the effectiveness of our primary casualty plan on our different platforms around the world.

Methods and Setting: Our medical assistance company is present in 28 countries but only 5 large regional platforms are accredited to deal with MCIs. A primary casualty plan, common to all entities, governs all aspects of MCI management (activation, coordination, forwarded team on the spot, relation with Foreign Affairs, communication with media…) under the responsibility of the Group Medical Direction. The present simulation was a tabletop exercise (no field deployment). The scenario was a terrorist attack (fire arms, no bomb) in a touristic place in Senegal with 10 killed and 20 severely injured people from 6 different countries. Coordination of the exercise was performed by the Group Medical Direction with the help of an external team of facilitators located in the country of occurrence, following a detailed chronogram and giving inputs/responding to the different platforms involved. There were also observers on each platform. The exercise was kept secret toward platforms. The main evaluative criterion was the concordance between the response each platform provided and the primary casualty plan (considered as the standard). 

Results: Alert was sent to 6 platforms with victims involved at 8:00 GMT on Sept 19, 2018. After 60 min, 1 regional platform had implemented a specific desk with dedicated staff, activated the local medical correspondent, contacted the other platforms within its region and the other regional platforms, and been in touch with Foreign Affairs Ministry. This platform was designated as leading platform for the entire group. After 90 min, this leading platform had collected a brief description of injuries for all victims and initiated local evacuations for those who required urgent/invasive procedures. One of the doctors of the team was ready to fly over there for local coordination of repatriation, agents having flight options ready. Secrecy was disclosed at this point and exercise ended.

Discussion: This simulation clearly identified platforms in which our primary casualty planis mature and those that need further attention or training. Since most managers and head of platforms were not present at the time of the exercise, it was also interesting to challenge on how not to rely on them. Also the email server of the company was down that morning, which invited to further think on communication tools. Formal debriefing was conducted with heads of platform and chief medical officers 10 days after the exercise and improvement measures were discussed and decided. The program of simulation will be continued.

10:55 - 11:00 #18482 - SP027 Somatic complaints in survivors after Typhoon Haiyan 2013 in the Philippines.
SP027 Somatic complaints in survivors after Typhoon Haiyan 2013 in the Philippines.

Background

Somatic complaints (i.e., somatization symptoms and pain) in survivors of natural disaster are frequent symptoms and a complicating factor in the treatment of these patients.

The main objective of this study is to analyze the prevalence of possible somatic complaints in survivors during phase 3 post Typhoon Haiyan 2013 in the Philippines.

Methods

One month after-disaster, between 23th of November  and 22th of December  2013, ARES Emergency Medical Team Type 1 Fixed have managed health care of survivors in Esteban – Burauen (Leyte - Eastern Visayas) and collected data: anagraphic data, prevalent symptoms and final diagnosis of these survivors. We defined pssible psychosomatic complaints those cases in which the prevalent symptom was either chest pain or abdominal pain or headache or malaise or hypertension and it was not possible to obtain an organic diagnosis after the diagnostic pathway. We analyzed the prevalence of psychosomatic complaints in our population and by using simple logistic regression we looked for predictive factors for or against the diagnosis of psychosomatic symptoms.

Results

1890 patients were visited: median age 31 (standard deviation 24), 54% female. 407 patients (21%) had possible somatic symptoms (40% abdominal pain, 25% chest discomfort/pain and palpitations, 19% headache, 11% malaise and 5% hypertension). 225 of these 407 patients (55%) were diagnosed as psychosomatic complaints (12% of the entire study population). The predictive factors for diagnosis of psychosomatic symptom were: malaise with OR of 1.40 (95% CI 1.15-1.71, p<0.01), headache with RR of 1.34 (95% CI 1.11-1.62, p<0.01), abdominal pain with RR of 1.06 (95% CI 0.89-1.26, p=0.5) and hypertension with RR of 1.25 (95% CI 0.91-1.72, p=0.2). The predictive factor against diagnosis of psychosomatic symptom was chest discomfort/pain and palpitations (RR 0.54, 95% CI 0.41-0.73, p<0.01).

Discussion and conclusions

The importance of diagnosing a psycosomatic complaint in patient who experinced natural disaster is the possibility of special treatment options. In the literature the prevalence rates of psycosomatic complaints, such as patients presenting persistent pain symptoms, after natural disaster range from 10 to 50%. Our data confirmed this moderately high prevalence,  in particular in a selected subgroup of patients with pain and/or malaise.

11:00 - 11:05 #18488 - SP028 Comparing training techniques in personal protective equipment use.
SP028 Comparing training techniques in personal protective equipment use.

Introduction:

While an emphasis has been placed on the importance of personal protective equipment (PPE), there are no standardized PPE training guidelines for EM physicians, though many hospitals require brief in-person annual trainings.  Physicians’ response to hazardous material events require PPE utilization to ensure the safety of victims, facilities, and providers; therefore, providing effective and accessible training is crucial. In the event of a real event, circumstances may not allow for an in-person presentation and an accessible video training may provide a useful alternative.

 

Methods:

A randomized trial was performed with sixteen EM residents divided into two sets of groups, with Groups 1 and 2 viewing a demonstration video and Groups 3 and 4 receiving a separate in-person training. The groups then donned and doffed while blinded evaluators assessed critical tasks utilizing a prepared evaluation tool.

 

Results:

Donning

During donning, the four groups were evaluated on fourteen individual critical tasks.  These tasks were meant to happen in sequence and were specifically included in both the video and in-person trainings.

Groups 1 and 2 (video trained) had a total of nine failures out of fifty-five evaluated possibilities - an error rate of 16.0% (95% CI 11.2% to 32.0%).  Frequently failed tasks involved checking the PAPR for functionality, and not performing a final Buddy check prior to entering the decontamination showers.

Groups 3 and 4 (in-person trained) had a total of eleven failures out of fifty-six evaluated possibilities - an error rate of 19.6% (95% CI 8.6%-28.5%).  Most frequently failed tasks also involved PAPR inspection and final Buddy check but had additional common failures in checking vital signs and providing hydration during the process.

Using a Fisher’s exact test to compare the number of failed demonstrated a two-tailed P value of 0.81, demonstrating no statistically significant difference between donning errors in the two sets of groups.

 

Doffing

During doffing, each of the four groups were evaluated on eleven individual critical tasks, also meant to happen in sequence.

Groups 1 and 2 had a total of fifteen failures out of forty-four evaluated possibilities with an error rate of 34.1% (95% CI 21.8% to 48.9%).  The failed tasks were largely evenly distributed.

Groups 3 and 4 had a total of twelve failures out of forty-four evaluated possibilities - an error rate of 27.3% (95% CI 16.2% to 42.0%).  Frequently failed tasks involved the removal of the PAPR hood and rechecking vital signs.

A Fisher’s exact test demonstrated a two-tailed P value of 0.64, showing no statistically significant difference in doffing errors between the two sets of groups.

 

Discussion:

In this pilot study, video and in-person training were equally effective in preparing residents for donning and doffing Level C PPE, with no statistically significant difference between the error rates in each modality.  Further research into this subject with an appropriately powered study is warranted to determine if this equivalence persists.

10:45 - 10:50 #17980 - SP029 Prospective study using a combined didactic and web-based learning curriculum to enhance emergency medicine education.
SP029 Prospective study using a combined didactic and web-based learning curriculum to enhance emergency medicine education.

Background:


Intern doctors are required to complete a term of at least eight weeks in emergency medical care in Australia to gain general registration.  This requirement along with a significant increase in medical graduates in recent years has created challenges in delivering a quality educational experience for intern doctors rotating through busy emergency departments.  This study attempts to assess the effectiveness of a blended emergency medicine intern education program that incorporates web-based learning into traditional classroom-based didactic sessions.

Methods:


This prospective study involved a convenience sample of intern doctors doing their emergency medicine term at two urban Australian emergency departments between April 2015 and January 2017.  Participation in the study was voluntary.  The Emergency Department General Education (EDGE) program is an emergency medicine intern education program that utilises a blended curriculum which incorporates web-based modules into weekly didactic and skills sessions.  All intern doctors rotating through the emergency departments of each study site hospital are given protected off the floor time each week to attend the program's educational sessions.  The program runs throughout the ten-week emergency medicine term and is run five times each academic year.  All interns are given access to the program's corresponding web-based learning modules (www.moodle.learnem.com.au) with completion of the web-based material being voluntary.

To assess change in medical knowledge base during the program, participants were administered two multiple choice examinations covering a variety of emergency medicine topics at the beginning (Week 1) and during the final week (Week 10) of the term.  To determine the study's primary endpoint, the impact of the program's web-based resources on improving participants' emergency medicine knowledge base, the median % of online modules completed by participants (75%) was used as a cut off to create two groups; those that completed < 75% and those that completed >75% of the web-based modules.  Student T-test was used to compare the improvement between Week 1 and 10 scores for all interns as well as the improvement between the two groups.  Mean Week 1 and Week 10 examination scores, Standard Deviation, and 95% confidence intervals (CI), were carried out for the two groups.  Intern satisfaction with the program was also assessed using a satisfaction survey.

Results:


The Average examination score obtained in Week 10 (80%) for all participating interns (N=85) was significantly greater than that achieved in Week 1 (68%; P<0.001).  The % improvement between the Week 1 and Week 10 scores of those that completed <75% (N=42) of web-based modules (16% mean; 95% CI 12-20%) and those that completed >75% (N=43) of web-based modules (27% mean; 95% CI 20-34%) showed a statistically significant difference (p=0.03).  Interns when surveyed were also highly satisfied with all aspects of the EDGE program. 

Discussion & Conclusions:


Educational programs that incorporate web-based learning into didactics have several advantages over traditional lecture-based education and have shown promise in the literature.  This study of a blended curriculum that utilizes web-based learning material shows promise in enhancing intern emergency medicine education.

SP030 The Impact of Clinical Supervision Shifts on the Resident Supervision Index in the Emergency Department of Qatar.

Background: Clinical supervision (CS) is an important foundational requirement to maximize education and assure patient safety. The resident supervision index (RSI) has been proposed as a validated tool in GME programs in the United States to measure the quality of CS. CS in a busy emergency department (ED) setting can be challenging due to the demands of clinical service.

Aim/Objectives: The Impact of Clinical Supervision Shifts on the RSI in the ED

 Method: We implemented special four hours shifts to commit faculty time for CS and measured its impact on the RSI. The study was done in a busy academic ED in Qatar with an annual patient attendance of around 450,000 and staffed by around 240 emergency medicine (EM) physicians including 48 residents and 58 fellows.

Results: A total of 336 responses of individual CS encounters were collected over a period of 8 months of CS shifts. The CS encounters were a mix of case discussion, review of test results, supervision of clinical procedures, WBAs and Ultrasound. The faculty was fully involved in patient care in 20.8% of encounters, partially involved in 46.4% and offered advice in 25.6%. The CS contributed to the understanding of the case by the supervisee in 94.0%. The CS resulted in significant impact on all aspects of the RSI – changes were noted in history in 12.2%, examination findings in 14.4%, interpretation of diagnostic data in 23.1%, diagnosis in 13.6%, overall assessment in 21.6% and in the management plan in 35.1%.

 

Discussion:  Unlike other instruments to assess the quality of supervision, RSI provides quantitative measures of resident supervision. Better supervision will help residents to become skilled physicians and will also help the importantly in patient care.

Conclusion:  

CS shifts in a busy ED resulted in a significant overall impact on the RSI and have the potential to offer major benefits to the educational experience of learners and to patient safety.

 Further studies are recommended to assess the use of RSI to assess outcomes of educational programs on patient’s outcomes

10:55 - 11:00 #19289 - SP031 Pulseless electric activity as the last rhythm recorded before first adrenaline administration is associated with sustained return of spontaneous circulation in out-of-hospital cardiac arrest cases with adrenaline administration.
Pulseless electric activity as the last rhythm recorded before first adrenaline administration is associated with sustained return of spontaneous circulation in out-of-hospital cardiac arrest cases with adrenaline administration.

Backgrounds and Aims: Adrenaline is administered to patients with out-of-hospital cardiac arrest (OHCA) after basic life support and/or advanced airway management. Time interval between start of CPR by emergency medical service (EMS) and adrenaline administration varied depending on regions, levels of EMS and circumstances of OHCA. It is not rare that ECG rhythm conversion from the initial rhythm to other rhythms are recorded during the BLS period. The first goal of basic and advanced life supports in OHCA cases is sustained return of spontaneous circulation (SROSC) although benefit of each resuscitation procedure should be determined by neurologically favourable outcome. This study aimed to identify the factors associated with SROSC in OHCA groups with adrenaline administration before and after hospital arrival (prehospital and in-hospital first adrenaline groups), with consideration of ECG rhythm changes before adrenaline administration.

Methods: In this retrospective analysis of prospective data collection, we extracted the data for 3,729 adult (≥ 8 y) OHCA cases with adrenaline administration before hospital arrival and 4,070 cases with adrenaline from the population-based OHCA data that were prospectively collected during the period of 2011‒218. Univariate and stepwise multivariable logistic regression analysis were applied to disclose the factors associated with SROSC.

Results: The rates of ECG rhythm conversion in prehospital and in-hospital first adrenaline groups correlated with the initial rhythm (P <0.01): 59.5% and 72.9%, respectively in cases with ventricular fibrillation/tachycardia (VF/VT) as initial ECG rhythm , 24.3% and 43.0% in pulseless electric activity (PEA), 7.0% and 5.6% in asystole. In univariate analyses, both initial rhythms and the last rhythms recorded before first adrenaline administrations were associated with SROSC (P <0.01). However, the rate of SROSC was highest when the initial ECG rhythm was VF/VT (43.1% and 35.9%, in prehospital and in-hospital first adrenaline groups respectively) and when the last rhythm recorded before adrenaline administration was PEA (46.1% and 35.9%.respectively). Stepwise multiple logistic regression analyses revealed that PEA as the last rhythm recorded before adrenaline administration was better predictor of SROSC than VF/VT as initial ECG rhythm and that an interaction for SROSC exists between the initial and last ECG rhythms. Any prehospital defibrillation attempt before the first adrenaline administrations was not a major factor associated with SROSC: P = 0.23 and P = 0.69, in prehospital and in-hospital adrenaline groups, respectively. The overall rate of SROSC in the prehospital first adrenaline group (24.9%, 928/3729) was higher than that in the in-hospital first adrenaline group (15.8%, 644/4070).

Conclusions: Rhythm conversions to PEA before first adrenaline administration are likely to be associated with SROSC. PEA as the last rhythm recorded before adrenaline administration is a good predictor of SROSC.

11:00 - 11:05 #19072 - SP032 The effectiveness of teaching limited compression ultrasound for diagnosing lower extremity DVT in primary health care.
SP032 The effectiveness of teaching limited compression ultrasound for diagnosing lower extremity DVT in primary health care.

Background: According to current literature a limited compression ultrasound (LCUS) protocol is safe to diagnose or exclude lower extremity deep venous thrombosis (DVT). It is a good option to a whole leg ultrasound performed by a radiologist especially in remote health care units where the availability of radiological services is limited and also in emergency department performed by emergency physician (EP).

Objective: To determine whether teaching LCUS to general practitioners (GP) reduces the number of patients with a suspected lower extremity DVT referred to a hospital for US examination safely.

Methods: During 2015-2016, a physician with 5 years of experience in diagnostic US (author Hannula) trained the GPs (n=13 working in Saarikka Primary Care Public Utility (catchment area 18.000 inhabitants) to use LCUS. The number of annual referrals due to a suspected DVT from Saarikka to the closest hospital were evaluated before and after training. The incidence of DVT was considered to be constant, thus the reduction of referrals was interpreted to happen because these patients were diagnosed and treated in primary health care without referring them to hospital. Safety was evaluated by examining all patients from Saarikka area who were diagnosed pulmonary embolism (PE) in nearest hospital during study years and following 3-month periods. Also patients referred to consultant radiologist were examined to find any possible false negative DVTs in LCUS.

Results: In 2014, the number of annual referrals due to a suspected DVT was 60. In 2017 the amount had reduced to 16 with a decrease of 73,3%. The incidence of referrals per 1000 person-years decreased from 3.21 to 0.89. (IRR 3.58, 95% CI 2.04 – 6.66, p<0.001). The annual numbers of PEs were 12 and 23 respectively. None of PE patients had a LCUS performed prior to diagnosis.  There were 13 and 16 referrals to consulting radiologist respectively with no false negative DVTs found.

Conclusions: Teaching a LCUS protocol to GPs seems to effectively and safely reduce the number of referrals to hospital due to a suspected DVT.

10:45 - 10:50 #18477 - SP033 Mdivi-1 protects CD4+T cells against apoptosis via balancing mitochondrial fusion-fission and preventing the induction of endoplasmic reticulum stress in sepsis.
SP033 Mdivi-1 protects CD4+T cells against apoptosis via balancing mitochondrial fusion-fission and preventing the induction of endoplasmic reticulum stress in sepsis.

Background:

Apoptosis of CD4+T cells plays a central role in the progression of sepsis because it is associated with subsequent immunosuppression and the lack of specific treatment. Thus, developing therapeutic strategies to attenuate apoptosis of CD4+T cells in sepsis is critical. Several studies have demonstrated that Mdivi-1, which is a selective inhibitor of the mitochondrial fission protein dynamin-related protein 1 (Drp1), attenuates apoptosis of myocardial cells and neurons during various pathologic states. The present study revealed the impact of Mdivi-1 on apoptosis of CD4+T cells in sepsis and the potential underlying mechanisms. We hypothesized that Mdivi-1 ameliorated apoptosis in CD4+T cells by re-establishing mitochondrial fusion-fission balance and preventing the induction of endoplasmic reticulum stress in experimental sepsis.

Methods:

It is an original study. We used lipopolysaccharide (LPS) stimulation and cecal ligation and puncture (CLP) surgery as sepsis models in vitro and in vivo, respectively. Apoptosis and cell viability of CD4+T cells were assessed by TUNEL assay and CCK8 assay. Protein levels were measured by western blotting. And mitochondrial morphology was observed by electron miscrosope.

The data were represented as the mean ± standard deviation (SD) using PSS (version 20.0). A one-way ANOVA was used to analyze significant differences between three or more groups and an unpaired Student’s t-test was used to analyze significant differences between two groups and significance was defined as P<0.05. GraphPad Prism 6 (San Diego, CA, USA) were used for the figure design.

Results:

Firstly, Mdivi-1 increased the cell viability of CD4+T cells and attenuated apoptosis of CD4+T cells both in vitro and in vivo. Secondly, the potential mechanism underlying the protective effect of Mdivi-1 involved Mdivi-1 re-establishing mitochondrial fusion-fission balance in sepsis, as reflected by the expression of the mitochondrial fusion proteins MFN2 and OPA1, Drp1 translocation, and mitochondrial morphology, as observed by electron microscopy. Moreover, Mdivi-1 treatment reduced reactive oxygen species (ROS) production and prevented the induction of endoplasmic reticulum stress (ERS) and associated apoptosis. After using tunicamycin to activate ER stress, the protective effect of Mdivi-1 on CD4+T cells was reversed. Together, Mdivi-1 attenuated apoptosis of CD4+T cells is probably through re-establishing mitochondrial fusion-fission balance and prevented the induction of ER stress.

Discussion and Conclusion:

Recent studies and clinical findings have demonstrated that apoptosis of T lymphocytes has a considerable involvement in immunosuppression and is critically related to the outcome of sepsis. Here, our study showed that apoptosis in CD4+ T cells was increased after LPS administration and CLP surgery. Consequently, it is urgent to develop novel therapeutic strategies to attenuate apoptosis in CD4+ T cells during sepsis to affect the outcome. Our results demonstrated that Mdivi-1 protected against apoptosis of CD4+T cells and balancing mitochondrial fusion-fission and preventing the induction of endoplasmic reticulum stress in experimental sepsis are probable mechanisms involved in it. Mdivi-1 is a probable novel therapeutic strategy that targeted apoptosis in CD4+ T cells to affect the outcome of septic patients.

SP035 An observational study of intravenous drug users presenting with groin swelling/pain to the Emergency Department.

Background

 

Intravenous drug users (IVDUs) commonly present to the emergency department (ED) complaining of pain and/or swelling in the groin after recent injection. Clinicians concerns include necrotising fasciitis, psuedoaneurysms, abscess and DVT. There is little data available on how common these diagnosis are or what antibiotics to give. Therefore, decisions regarding imaging, antibiotics and specialty involvement are challenging. This study aimed to address this by answering the following questions: what is the best antibiotic to give, do they need imaged in the ED and how do we identify the particularly sick patient?

 

Methods

This was an observational study of patients presenting to the ED at a large tertiary hospital in Aberdeen, Scotland. Those patients that were included attended the ED between 1st January 2015 and 31st December 2016 and had a diagnosis of ‘local infection of skin and cutaneous’, ‘cellulitis’, ‘other bacterial infections’, ‘cutaneous abscess’, ‘necrotising fasciitis’, ‘septic shock’ or ‘septicaemia’ or had a CT or USS in the ED.

 

Patients who did not present with pain and/or swelling of the groin and a history of recent intravenous drug injection were excluded, as were those with no microbiology samples.

 

The remaining group consisted of 30 patients. Documentation, radiology and laboratory results were analysed for these patients.

 

Results

Within the 30 patients, 13 different combinations of antibiotics were administered. 11 patients were bacteraemic. Samples obtained from blood cultures, deep tissue samples, pus/fluid samples and superficial samples all grew similar organisms, with a significant presence of anaerobes, as well as Staphylococcus, Streptococcus and gram negative bacteria.  

 

3 patients had a pseudoaneurysm (one of which was not identified on CT as an abscess was compressing the vessel), 5 had features of necrotising fasciitis on CT and required multiple debridements, 1 had necrotising myositis, 12 had an abscess and 11 had a DVT. 6 required HDU or ICU care.

 

Patients with significant pathology were difficult to recognise. Most were given a low triage category, had relatively normal observations and only mildly raised lactates even if they ultimately required theatre from the ED and then ICU. A LRINEC score of ≥ 6 or 8 was not a good discriminator of need for urgent theatre but none of those who had a score of <6 had time critical findings on CT or at theatre. In 4 out of the 5 cases of requiring urgent repeated debridments in theatre, the CT in the ED did change management because it had not been clinically apparent how significnant the pathology was.

 

17% of these patients have subsequently died (as of January 2019).

 

Conclusions

Based on the organisms that were grown and the resulting sensitivities, if the patient does not warrant necrotising fasciitis specific antibiotics, Flucloxacillin 2g IV and Metronidazole 500mg IV are advised, with Vancomycin to be used in cases of penicillin allergy.

 

A substantial proportion of these patients will have significant time-critical pathology and it is challenging to clinically identify this. We therefore propose that all these patients should have CT angiography in the ED.

SP036 CHARACTERISTICS OF THE PATIENT WITH BACTERIEMIA IN EMERGENCY DEPARMENT.

INTRODUCTION

The bacteriemia is an important cause of morbidity and mortality in spite of the availability of a powerful antimicrobial therapy and the advances in the support attention. In the Hospitable first aid services, after the clinical evaluation of the feverish syndromes there is habitual the achievement of complementary tests, between which they emphasize the capture of hemocultivos.

TARGETS 

Main: To evaluate the patient's profile with bacteriemia in our health area 

Secondary: To determine the most frequent comorbidities that these present.

 

METHODOLOGY 

Observacional has designed an epidemiologic study to himself with retrospective character, in our hospital that is classified as of the second level and a population of 250000 inhabitants attends. The firs aid service receives approximately 9000 urgencies a month. There were selected patients who consulted for feverish syndrome in the year 2017 and it extracted them to itself hemocultivos. There were checked the case histories of the chosen episodes, variables being gathered as: age and sex, microorganism that isolated itself in the hemocultivo, pathologies previous to the patients, established treatment, I number of returns and mortality.

 RESULTS 

131 patients included with hemocultivos positives. The entire distribution of the sample for sex belonged to 73 males (55,7 %) and 58 women (44,3 %), being the median of age of 76 years, the minimal age 11 and the maxim 97. Of the obtained sample, 14 patients re-entered after being discharged and the mortality in whole was 10,7 %.

As for previous pathologies that they were presenting, it was obtained that 80 (61,06 %) was diagnosed of HTA, their 25 (19,08 %) of DM. As for the cardiovascular diseases, their 28 (21,37 %) had arrhythmias precedents, 6 (4,58 %) had suffered previous IAM, 7 (5,34 %) was presenting cardiovascular disease and 9 (6,87 %) heart failure. If we speak about respiratory illnesses, we are that their 19 (14,50 %) had been diagnosed previously of EPOC and 3 (2,29 %) of bronquiectasias. As for the renal illnesses, 28 of them were presenting ERC (21,37 %), receiving 4 of them hemodiálisis. If we speak about present digestive illnesses in our patients' sample, their 5 (3,81 %) was presenting hepatopatía established and 2 (1,52 %) ulcus. Finally as for the illnesses of neurological origin, their 23 (17,55 %) was presenting cerebrovascular illness and 20 (15,26 %) dementia.

CONCLUSIONS 

The bacteriemias collaborate to a high morbimortalidad incidence. In our series we obtained that the patient's profile is usually a 76-year-old male, with some associate comorbidity, being the pathology more often associated the HTA. On having analyzed the most frequent pathologies for systems, we obtain that the most frequent pathology associated with our patient's profile is that of cardiovascular origin, followed by the neurological one, in the third place the renal one, being the least frequent the digestive one

10:45 - 10:50 #18323 - SP037 Comparison of a subjective triage and Emergency Severity Index.
SP037 Comparison of a subjective triage and Emergency Severity Index.

Background: A three-level subjective triage was used to sort patients at the Emergency Department of University Hospital Motol, Prague, until 2018. P1 priority was defined as an emergency (a life- and/or health-threatening condition) to be seen by a physician immediately, P2 as an urgent case to be seen within an hour and P3 as conditions where the care can be delayed according to the current capacity. This was replaced by an objective triage using Emergency Severity Index v. 4 in 2018. Results of both approaches were compared during a one-month period.

Methods: Triage nurses were instructed to triage all the patients using both conventional subjective triage (P1-P3) and ESI v. 4 (P1-P5) and record both the priorities during December 2017. Former subjective P1 priority was replaced by P1 and P2 priorities, P2 by P3 and former P3 by new categories P4 and P5. Their decision making was supported by a paper ESI flow-chart and a computer application.

Results: Both priorities were recorded in 1,010 out of total 1,782 patients (56.7 %), 376 out of them were admitted to the hospital (37.2 %). The average priority using a subjective triage was 2.37 (median 2) and 3.11 using ESI (median 3). The correlation between both priorities was 0.71 (p < .00001). The new ESI priority was, in comparison to the previous subjective triage, lower in 62.9 %, the same in 35.0 % and higher in 2.1 %. A priority obtained by a subjective triage corresponded to ESI as stated above in only 62.2 % cases, in 33.7 % cases (340 cases, 139 out of them were admitted to the hospital, i.e. 40.9 %) it can be evaluated as a possible undertriage and in 4.1 % cases as an overtriage.

Discussion & Conclusions: Despite inevitable errors when using any objective triage system, a subjective triage, although done by an experienced triage nurse, might be burdened by errors in approximately 37 % cases, therefore a more sensitive five-level triage system using objective criteria and values is highly recommended.

SP038 Direct Admission to the Intensive Care Unit from the Emergency Department and Mortality in Critically ill Hematology Patients.

Background: The aim of this study was to assess the benefit of direct ICU admission from the emergency department (ED) compared to admission from wards, in patients with hematological malignancies requiring critical care.

Methods:Post hoc analysis derived from a prospective, multicenter cohort study of 1,011 critically ill adult patients with hematologic malignancies admitted to 17 ICU in Belgium and France from January 2010 to May 2011.The variable of interest was a direct ICU admission from the ED and the outcome was in-hospital mortality. The association between the variable of interest and the outcome was assessed by multivariable logistic regression after multiple imputation of missing data. Several sensitivity analyses were performed: complete case analysis, propensity score matching and multivariable Cox proportional-hazards analysis of 90 day-survival.

Results: Direct ICU admission from the ED occurred in 266 (26.4%) cases, 84 of whom (31.6%) died in the hospital versus 311/742 (41.9%) in those who did not. After adjustment, direct ICU admission from the ED was associated with a decreased in-hospital mortality (adjusted OR: 0.63; 95%CI: 0.45-0.88). This was confirmed in the complete cases analysis (adjusted OR: 0.64; 95%CI: 0.45-0.92) as well as in terms of hazard of death within the 90 days after admission (adjusted HR: 0.77; 95%CI 0.60-0.99). By contrast, in the propensity score matched sample of 402 patients, direct admission was not associated to in-hospital mortality (adjusted OR: 0.92; 95%CI: 0.84-1.01).

Conclusions: In this study, patients with hematological malignancies admitted to the ICU were more likely to be alive at hospital discharge if they were directly admitted from the ED rather than from the wards. Assessment early predictors of poor outcome in cancer patients admitted to the ED is crucial so as to allow early referral to the ICU and avoid delays in treatment initiation and mis-orientation.

10:55 - 11:00 #19262 - SP039 Experimental use of machine learning to generate next-activity recommendations in the emergency department.
SP039 Experimental use of machine learning to generate next-activity recommendations in the emergency department.

Background

Patients in the emergency department (ED) need a diagnostic work-up from complaints upon presentation to a correct treatment. The intent is to recognize frequently occurring diagnoses and to not miss serious, potentially life-threatening disorders. Emergency physicians continuously refine information to rearrange the probabilities of seriousness and likelihood of potential diagnoses. They consider the patient characteristics and results of technical investigations and implement clinical decision rules. However, the environment of the ED (e.g., the availability of resources) and the personal characteristics of the physician (e.g., experience, memory, interpersonal skills) also contribute to the decision-making.  Therefore, a secondary source of knowledge proposing the next activity to perform (e.g. take an X-ray) and reflecting all preceding experiences with similar patients in the setting of the specific ED would be an improvement.

Methods

Design Science methodology was applied to develop techniques that generate recommendations for the next activity to be executed for patients in an ED, using a combination of historic data, process management and machine learning. In this project, historic data were used from the ED of the Maria Middelares hospital in Ghent, Belgium consisting of 41657 patients. For each patient, the timeline of all registered events in diagnosis and treatment was reconstructed, starting from the registration at the entrance and ending with either a discharge or hospital admission. Additionally, keywords (e.g., “anemia” in the medical history) and other data values (lab and X-ray) were identified.

Forty strategies that each prioritize different similarities between the current and historic patients based on either activities, data or both, were prototyped to generate probabilities that serve as next-activity recommendations. They were trained on a subset of the patients and evaluated by comparing the predicted with the actual next activities of the other patients. The evaluation criteria were the calculation time and five performance measures:  rank, accuracy, brier score, log loss and rank score.

Results

The Design Science methodology identified 1350465 data events with 625758 activities and 117 unique activities in patient timelines with a maximum of 128 subsequent activities. The best performing strategy achieved an average top ranked recommendation accuracy of 60% and the correct next activity was ranked in the top 3 on average, with an average calculation time of less than 0.4 seconds.

 

Conclusions and future directions

The proposed strategies were fast and sufficiently accurate to help remind emergency physicians of alternatives or forgotten activities, without impacting their decision freedom. These experiments are to be seen as operational process support, i.e. not to try to impose a specific diagnosis or therapy but merely suggesting suitable next activities. It could prevent medical errors and promote a more uniform diagnostic approach. Future research is aiming to further improve the accuracy of the first recommendation and to allow the introduction of clinical pathways. The ultimate goal is to provide real-time recommendations for the possible next-step activities of all patients present at the same time in the ED and for the prioritization of patients, based on their characteristics and results of their preceding processes.

SP040 A cross-sectional survey among asylum seekers with non-urgent complaints: Why do they seek help in the ED?

Background

In line with global trends, European countries have witnessed increase usage of Emergency Departments (ED) services for low acuity complaints. Research on ED utilization in Europe has shown that AS comprise a greater proportion of non-urgent ED visits. Although a variety of factors associated with the use of ED services for low acuity complaints, studies have yet to examine the reasoning underlying hospital-based ED usage for low acuity complaints among patients with asylum seeker (AS) status.

Methods

We conducted a prospective cross-sectional, single center study. Data was collected during 01/12/2016 and 31/07/2017 among AS and Swiss residents attending the ED of the University Hospital, Bern (Switzerland). The survey included questions about motives to present in the ED for low acuity complaints, patients and the treating physicians were asked to answer a questionnaire.

Study participation was voluntary, free of any compensation and individual verbal and written patient consent was obtained before answering the survey. The study was presented to and approved by the regional ethics committee of the Canton of Bern, Switzerland.

Results

AS and Swiss residents differed in several reasons for seeking care in the ED. 30.2% of the AS patients reported to have no knowledge about the Swiss healthcare system (HCS). The perception of medical urgency as reported by the AS and the treating physician showed a significant mismatch, e.g. only 14.2% of the AS-patients perceived their problem as non-urgent in contrast to 43.3% given by the treating ED physician.

With more than half of the AS, direct communication was impossible and in 70.2% of this cases family and friends were used as translators.

Outcomes, like length of stay (LOS), discharge type, and time of visit did not differ between the two groups.

Conclusion

Lacking knowledge about the healthcare setting in the reception country, language barriers, and the perceived urgency of medical care are the main reasons for AS to seek care in ED for primarily low-acuity medical issues. In both groups, convenience and the perceived level of urgency played a role in the decision-making to present themselves in the ED.

Measures to increase health literacy and provision of easily accessible primary care could improve quality of care and reduce the usage of ED as primary care providers in AS. Implementation and usage of professional translator service will relieve family and friends from this role and might provide better and equal care.

11:10 - 11:20 #18155 - OP037 Pre-hospital lactate and hospital troponin: short-term prognostic implications in the patient with a heart attack code, a observational prospective study.
OP037 Pre-hospital lactate and hospital troponin: short-term prognostic implications in the patient with a heart attack code, a observational prospective study.

Introduction: chest pain (ischemic heart disease) represents one of the leading causes of mortality, one of the most frequent causes of hospital admission, and one of the most common causes of consultation and care of Prehospital Emergency Medical Services (PhEMS).

The main objective was to evaluate the capacity of prehospital lactic acid (PLA) vs hospital troponin (HT), to predict early mortality at two days from the index event in patients with chest pain (ischemic heart disease).

Material and methods: Longitudinal prospective observational study, between April 1 and December 31, 2018. The study was developed on a reference population of 1,021,086 inhabitants, distributed in three provinces of Spain (Burgos, Salamanca and Valladolid) . All the hospitals included in the study have Intensive Care Unit (ICU) and hemodynamic service. It was considered that a patient fulfilled criteria to be included in the study if he had been attended by Advanced Life Support Units and transferred to the emergency services with a main diagnosis of chest pain (ischemic heart disease), and did not meet any exclusion criteria: under 18 years old, cardiorespiratory arrest, exitus and pregnant women.

Demographic data (age and gender) and PLA were collected during the first contact with the patient in prehospital care. To obtain the PLA values, the Accutrend Plus measuring device (Roche Diagnostics, Mannheim, Germany) was used. HT was collected in the Emergency Department at the hospital level with the cobas b 123 POC system (Roche Diagnostics, Mannheim, Germany).

The days of admission, need for ICU and / or hemodynamics and mortality data were obtained by reviewing the patient's electronic history at 30 days.

The main dependent variable was mortality from any cause in the hospital before the first two days from the index event.

The area under the curve (AUC) of the receiver operating characteristic (ROC) was calculated for each biomarker in terms of 2-day mortality, as well as the best score that offered greater sensitivity and joint specificity.

Results: a total of 258 patients were included in our study. The median age was 68 years (IQR: 58-81 years), 30.2% of them were women. The 2-day mortality was 7.4% (19 cases). 49.2% (127 cases) of patients required ICU.

The PLA obtained an AUROC for the two-day mortality of 0.918 (0.83-1, p <0.001), and the HT of 0.727 (0.59-0.85, p = 0.001). When comparing both curves, significant differences were observed (p = 0.001).

The value with the best sensitivity and specificity overall for the PLA was 4.1 mmol/L, sensitivity of 94.7% (75.4-99.1), specificity of 79.9% (74.4-84.5), positive predictive value 27.3 (18.0-39.0), negative predictive value 99.5 (97.1-99.9), Likelihood ratio (+) 4.72 (3.59-6.21), Likelihood ratio (-) 0.07 (0.01-0.45) and odds ratio 71.63 (9.33-549-97).

Conclusions: The use of PLA presents a very high AUROC in patients with chest pain (ischemic heart disease). The PLA can help PhEMS in the selection of the most appropriate hospital center, with acute cardiac care unit and hemodynamic unit, in order to reduce morbidity and mortality due to this prevalent pathology.

OP038 Effectiveness of hypnosis for the prevention of anxiety during coronary angiography: The HypCor Study.

Abstract

 

Background – Coronary angiography is the gold standard for the diagnosis of coronary artery disease. This procedure is nevertheless a source of anxiety given the inconvenience caused by its invasiveness but also due to the consequences linked to the discovery of potential diseases.

Aim - The aim of this study was to determine the effectiveness of hypnosis on reducing patient anxiety prior to coronary angiography.

Methods – A total of 169 patients with non-urgent indications of coronary angiography and no history of prior coronary angiography were randomized to a Hypnosis or Control group. Patients in the Hypnosis group underwent a hypnosis session with posthypnotic suggestions in self hypnosis, while those in the control group had a conversational interview with the hypnotherapist. The primary endpoint was the level of anxiety prior to the exam assessed by the Spielberger State-Trait Anxiety Inventory (STAI-Y A).

Results - Performing a hypnosis session did not translate into a significant decrease in anxiety prior to the procedure. The use of midazolam was lower (5% in the Hypnosis group versus 12%, p=0.05). Systolic blood pressure (SBP) was significantly lower before the examination (p = 0.01). There was no adverse effect secondary to hypnosis. There was no statistically significant difference between the 2 groups for the occurrence of complications due to the procedure.

Conclusion - In the present study, performing a hypnosis session upstream of a coronary angiography, with suggestions in self-hypnosis to be performed during the procedure, did not reduce the state anxiety measured immediately before the intervention. In contrast, a significant reduction in SBP was observed in the Hypnosis group. There appears to be a possible reduction in the prescription of anxiolytics through hypnosis, although the latter necessitates confirmation in a larger-scale study.

11:30 - 11:40 #18548 - OP039 Could the YEARS algorithm be used to exclude PE during pregnancy? Data from the CT-PE-pregnancy study.
OP039 Could the YEARS algorithm be used to exclude PE during pregnancy? Data from the CT-PE-pregnancy study.

Introduction

In the recently published ARTEMIS study, the YEARS algorithm was shown to safely exclude pulmonary embolism (PE) and reduce usage of computed-tomography pulmonary angiogram (CTPA) among pregnant women with suspected PE. However, further validation is desirable prior to its implementation in clinical practice. Our aim was to externally validate the YEARS algorithm in pregnant women with suspected pulmonary embolism.

Methods

We performed a post-hoc analysis of a prospective management outcome study for PE diagnosis in pregnant women. PE was diagnosed using an algorithm that combined the revised Geneva Score, D-dimer test, bilateral lower limb compression ultrasonography and CTPA. All the items necessary to follow the YEARS algorithm were prospectively collected at the time of the study by the attending physician. The primary outcome was the rate of adjudicated symptomatic venous thromboembolic events at the 3-month follow up.

Results

Of the 395 women included in the original study, 371 were available for the present analysis. PE prevalence was 6.5%. Among the 371 women, 91 (25%) had no YEARS item, while 280 (75%) had one item or more: 14 had hemoptysis (3.8%), 55 had signs or symptoms of DVT (14.8%, of them 5 had a confirmed DVT on ultrasound) and pulmonary embolism was the most likely diagnosis for 262 patients (70.6%). When combined with D-dimer levels (<1000 ng/mL in women with zero item, and <500 ng/mL in women with ≥1 item), 77 women (21%) met the criteria for PE exclusion and would not have undergone a CTPA as per the YEARS algorithm. None of these 77 women had PE diagnosed during the initial work up or 3-month follow up. Therefore, the failure rate of the YEARS algorithm in our pregnant women population was 0/77 (95% confidence interval 0.0-3.9).

Discussions

These results confirm those from the recently published ARTEMIS prospective management study and provide additional evidence that the YEARS algorithm appears safe for pregnant women. Almost twice as many women could be spared from radiating imaging tests compared to the traditional algorithm. Given that D-dimer physiologically rises though pregnancy, the use of a higher D-dimer threshold (< 1000ng/ml) among patients with zero YEARS item could account for the higher diagnostic yield of the YEARS algorithm.

Limitations

The total number of women with a negative YEARS algorithm was small and the confidence interval around the estimation of PE prevalence in this group was wide, above the usual recommended limit for safe exclusion, precluding any definite conclusion to be drawn from the study. Also, in the CT-PE-pregnancy study, the likelihood of an alternative diagnosis (which is part of the Wells score but not of the Geneva score) had no consequence on patients’ management, which could have impacted the way physicians assessed this variable.

Conclusion

In our study, application of the YEARS algorithm would have resulted in safe exclusion of PE in 1 out of 5 pregnant women without the need for radiating tests, further supporting the use of the algorithm in this population.

OP040 Pleuritic chest pain. Diagnosis of pulmonary embolism with lung ultrasound. US Wells Project.

Background
Pleuritic chest pain is a common presentation in ED and it could sometimes be related to pleural irritation due to pulmonary infarct in pulmonary embolism (PE). Lung ultrasound (LUS) can detect pulmonary infarct, however its diagnostic accuracy for PE in a selected population presenting with pleuritic chest pain is unknown. The aim of the study is to analyze the performance of LUS in the diagnosis of PE in patients complaining of pleuritic chest pain. 

Methods

We combined individual patient data from three prospective cohort studies (one monocentric and two multicentric) involving patients evaluated for suspected PE in which LUS was performed at presentation. We extrapolated data regarding patients with and without pleuritic pain, and re-assessed the performance of LUS in the two populations for comparison.

Results

Among the 872 patients suspected of PE considered in the three studies, 217 (24.9%) presented with pleuritic chest pain and 655 (75.1%) without. Overall, 279 patients (32%) were diagnosed with PE. Pooled sensitivity of LUS in patients with and without pleuritic pain was respectively 81.5% (95%CI 70-90.1%) and 59.3% (95%CI 38.8-77.6%) (p <0.01). Specificity of LUS was similar in the two groups, respectively 95.4% (95%CI 90.7-98.1%) and 94.8% (95%CI 92.3-97.7%) (p>0.05). In patients with pleuritic pain, a diagnostic strategy combining Wells score with LUS performed better in terms of sensitivity (93%, 95%CI 80.9-98.5% vs 90.7%, 95%CI 77.9-97.4%), negative predictive value (96.2%, 95%CI 89.6-98.7% vs 93.3%, 95%CI 84.4-97.3%) and efficiency (56.7%, 95%CI 48.5-64.9% vs 42.5%, 95%CI 34.3-50.7%), than the conventional strategy based on Wells score and d-dimer.

Conclusion
In a population of patients suspected for PE, LUS for PE showed better sensitivity when applied to the subgroup complaining of pleuritic chest pain. In these patients, a diagnostic strategy based on Wells score and LUS performs better to exclude PE than the conventional rule based on clinical scoring and d-dimer.

OP041 Diagnostic accuracy of conventional chest radiography for acute aortic syndromes: results from ADVISED prospective multicenter study.

ABSTRACT

Purpose. Guidelines recommend chest radiography (CR) in the workup of suspected acute aortic syndromes (AAS), if the pre-test clinical probability is low. However, the diagnostic impact of CR integration for rule-in and rule-out of AAS is unknown.

Methods. We performed a secondary analysis of the ADvISED multicenter study. Emergency Department (ED) outpatients were eligible if AAS was clinically suspected. Clinical probability was defined with the aortic dissection detection risk score (ADD-RS). CR was evaluated blindly by a radiologist, who judged on mediastinum enlargement (EM) and other signs.

Results. 1030 patients were analyzed, including 48 (4.7%) with AAS. The sensitivity and specificity of CR (any sign) were 54.2% (95%CI 39.2-68.6%) and 92.4% (95%CI 90.5-93.9%), with moderate inter-observer agreement between attending physician and radiologist for EM (k=0.44). CR integration increased the diagnostic accuracy over ADD-RS (AUC 0.87 vs 0.66; P<0.001). The sensitivity and specificity of a CR-integrated strategy were 68.8% (95%CI 53.6-80.9) and 76.5% (95%CI 73.7-79.1). CR-integrated rule-in (ADD-RS>1 or CR-positive) applied to 264 vs 130 patients with ADD-RS>1 alone, including 15 with AAS and 119 false positives. CR-integrated rule-out (ADD-RS≤1 and CR-negative) applied to 766 (74.4%) patients, including 15 with AAS (31.3% of cases).

Conclusions. In this observational study, CR integration with clinical probability assessment showed modest rule-in efficiency and insufficient sensitivity for conclusive rule-out. The pragmatic impact of CR on the workup of AAS appears questionable.

12:00 - 12:10 #19175 - OP042 Myocardial strain as a marker of disease severity in infants with bronchiolitis, a pilot study.
OP042 Myocardial strain as a marker of disease severity in infants with bronchiolitis, a pilot study.

Introduction: Bronchiolitis is a respiratory viral infection, in most severe cases this may lead to acute respiratory failure and pulmonary hypertension (PH), although echocardiographic evidences of PH have been reported in mild cases too. PH may potentially affect cardiac function, though this has never been investigated so far.

Aim: To evaluate cardiac function in infants with bronchiolitis.

Methods: Infants with evidence of bronchiolitis were included. All cases underwent viral antigen testing on nasopharyngeal aspirates, arterial blood gas test and functional echocardiography within 24 hours from admission. Systolic and diastolic function for the left ventricle (LV) and right ventricle (RV) were assessed with longitudinal strain, as a measure of percentage of myocardial deformation. Based on existing normative data cut-off for RV and LV function were assessed. PH was defined by the presence of tricuspid regurgitation jet (TR) and septal position quantified by end-systolic eccentricity index (EI ES). Main outcomes (duration of respiratory support, DRS, and length of stay, LOS), were collected.

Results:  28 infants, of which 15 males and 13 females, age 31 ±19 days, weight 3.160 (1.960–4.010) kg. 17 and 11 patients had syncytial respiratory virus and rhinovirus infection respectively. Cases with bronchiolitis showed significantly lower values of LS for both ventricles (LV: p0.02 and RV: p0.03) compared to normative values. Among these, 12 (43%) had normal biventricular function, 10 (36%) showed LV dysfunction and 6 (21%) a biventricular dysfunction. No significant data were found for TR and EI ES. Infants with biventricular dysfunction showed a significant increase in LOS (p0.03) and DRS (p0.03) compared to those with normal function.

Conclusions: Infants with bronchiolitis may present myocardial impairment. Cardiac function may be related to disease severity and should be routinely assessed. Future studies with larger samples are needed to confirm these data.

12:10 - 12:20 #19224 - OP043 A comparison among three clinical scores to identify low risk patients with non traumatic chest pain: a retrospective study.
OP043 A comparison among three clinical scores to identify low risk patients with non traumatic chest pain: a retrospective study.

Background:

In Italy, non-traumatic chest pain represents about 6% of admission to the Emergency Department (ED), but only 15-20% of these is due to acute coronary syndrome (ACS). There are many scoring systems developed to stratify patients depending on the risk of major adverse cardiac events (MACE), particularly the HEART score, the North American Chest Pain Rule (NACPR), the Not Objective Testing Rule (NOT).

The aim of this study is the comparison of these scores in order to identify patients who can be safely discharged from the ED.

Methods:

We analysed data obtained from a previous monocentric, retrospective, observational study performed in order to analyse modified Heart Score in patients admitted to ED of Policlinico Sant’Orsola in Bologna for chest pain, between January 1 and June 30, 2014.

We enrolled 1597 consecutive 18 or older aged patients for acute non-traumatic chest pain, irrespective of comorbidities, medical treatments and the onset of symptoms. Of them, 262 were excluded because of anginal equivalent without chest pain, significant ST-segment elevation, impossibility to complete the physician’s evaluation or the follow up. 191 patients were excluded because of the lack of the second troponin, necessary for NOT and NACPR. The final population is then composed by 1144 patients.

Patients were recalled within 180 days in order to register MACE.

We used Heart Score modified for the EKG criteria: two points were assigned in case of typical acute ischemia (significant ST-segment depression and T wave changes), 0 points in the case of a normal EKG or a single known anomaly without ST-T abnormalities, one point was assigned in the other cases. Instead, we used unchanged version of the NACPR and NOT.

The performance of these scores was evaluated with the estimates of sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV). We also compared the proportion of MACE in each low risk category of Heart Score, NACPR and NOT.

Results:

According to data analysis, the average age of the population is 60 ± 19. The Heart Score identified 26% (n=297) of patients in the low risk category, NACPR 9.3% (n=107) and NOT 11% (n=123). In this class of patients, all the scores showed a sensibility and an NPV of 100% for MACE, as nobody of these presented major adverse cardiac events.

Discussion & conclusion:

According to the literature, all these scores have high NPV, which reflects their capability to identify low risk patients for ACS. Instead Heart Score identified a significantly greater number of patients than the other two scores ( p<0.0001).

This likely depends on the inclusion criteria, in particular the exclusion of patients aged greater than 50 years old, who represent the majority of the ones admitted to the ED.

If these data were confirmed in new prospective studies, Heart Score would be used in clinical practice to safely discharge patients to the ED. In this way we could improve health costs and the hospital’s overcrowding.

12:20 - 12:30 #19241 - OP044 Blood pressure in the emergency department and incident cardiovascular disease: a retrospective cohort study.
OP044 Blood pressure in the emergency department and incident cardiovascular disease: a retrospective cohort study.

Background: High blood pressure (BP) is an established risk factor for cardiovascular disease (CVD), but hypertension remains a global challenge. Prevention, diagnosis, treatment and control of hypertension needs improvement. In the emergency department (ED), BP is measured on almost every patient in order to assess patients’ condition in the short-term, and many patients have BP levels above the threshold for hypertension. It is still unknown if BP in the ED is associated with long-term prognosis or how this BPs should be handled. The purpose of this study was to explore if BP obtained in the ED is associated with incident atherosclerotic cardiovascular disease (ASCVD), myocardial infarction (MI), or stroke.

Methods: All patients who visited two university hospital EDs between 2010 to 2016 with an obtained BP in the ED were included and studied regarding incident ASCVD, MI, and stroke. Systolic BP (SBP) and diastolic BP (DBP) were obtained through EDs databases and the endpoint diagnosis from the Swedish National Patient Register and Cause of Death Register. BP was categorized based on the definition of BP and hypertension grades. Cox proportional hazard regression was used in crude and adjusted models to estimate hazard ratios (HR), confidence interval (CI) and cumulative incidence for ASCVD, MI, and stroke. Age, sex, history of hypertension, CVD and diabetes mellitus were adjusted for, in adjusted models.

Results: A total of 300,272 patients were followed for a median of 42 months (range 0-84 months). Incident ASCVD occurred in 8,914 cases (MI 4,709 events and stroke 6,700 events). BP levels above normal (SBP: >120-129 mmHg, DBP: >80-84 mmHg) had a progressively increased association with ASCVD, MI, and stroke. In the adjusted model, SBP that corresponded to hypertension grade 1, 2, and 3 had a statistically significant association with ASCVD (SBP 140-159 mmHg: HR 1.15, 95% CI 1.06-1.24, 160-179 mmHg: HR 1.35, 95% CI 1.24-1.46, ≥180 mmHg: HR 1.59, 95% CI 1.46-1.73). Similar results were observed for DBP. DBP in the high normal category (85-89 mmHg), had a statistically significant association with ASCVD (HR 1.15, 95% CI 1.06-1.25) and stroke (HR 1.17, 95% CI 1.07-1.29). In the crude model, SBP ≥180 mmHg had the strongest association with ASCVD (HR 5.50, 95% CI 5.06-5.99). Patients with no history of hypertension had a stronger association with ASCVD (SBP ≥180 mmHg: HR 2.01, 95% CI 1.75-2.32), compared to patients with a history of hypertension (SBP ≥180 mmHg: HR 1.34, 95% CI 1.20-1.49). There was a similar association with ASCVD between directly discharged (SBP ≥180 mmHg: HR 1.55, 95% CI 1.36-1.76) and admitted patients (SBP ≥180 mmHg: HR 1.74, 95% CI 1.55-1.96). The six-year cumulative incidence of ASCVD was approximately 12% for SBP ≥180 mmHg compared to 2% for normal SBP (120-129 mmHg).

Conclusions: BP in the ED is associated with incident ASCVD, MI, and stroke with a stronger association for higher BP levels. High BP recordings in EDs should not be disregarded as isolated events, but treatment should be initiated, and patients should be referred to primary care for hypertension investigation.

12:20 - 12:40 #19268 - OP045 The CARE Rule and the CARE-HEART strategy to safely reduce troponin measurement in patients presenting with chest pain.
OP045 The CARE Rule and the CARE-HEART strategy to safely reduce troponin measurement in patients presenting with chest pain.

Objectives:

Current guidelines for patients presenting to the Emergency Department (ED) with chest pain but with no ST segment Elevation Myocardial Infarction (STEMI) on ECG are mainly based on serial troponin measurements. These strategies are safe but costly and time consuming, contributing to emergency departments’ overcrowding. Our main objective was to prospectively assess the reliability of the CARE rule, corresponding to the first 4 items on the HEART score and its association with the HEART score to safely rule-out Non-STEMI without troponin measurement (CARE) or with a single baseline troponin measurement (HEART).

Methods:

Prospective observational study in six EDs. Consecutive patients with non-traumatic chest pain and no formal diagnosis after examination and ECG were included and followed for 45-days. Items allowing computation of the CARE rule and HEART score were prospectively collected by the attending physician. The main study endpoint was the 45-day rate of MACE (myocardial infarction, percutaneous coronary intervention, coronary bypass and cardiac death). Secondary endpoint was the theoretical reduction of the number of required troponin tests, computed by the difference between the actual number of troponin tests with the theoretical number of troponin test needed if the CARE-HEART strategy would have been applied. The procedure would be deemed reliable if, when negative, the rate of MACE is <1% with an upper limit of the 95% confidence interval (95% CI) <3%.

Results:

From 1452 patients included, 1402 were analysed, 1285 had at least one troponin measurement and 97 (7%) had MACE during the follow-up. The CARE rule was negative for 279 (20%) patients and one presented a MACE: 0.4% (1/279, 95% CI: 0-2.0%). The CARE-HEART strategy was negative for an additional 476 patients (34%) and one of them had a MACE: 0.3% (2/755, 95% CI: 0-0.9%). The CARE-HEART strategy could theoretically have spared 360 troponin measurements (19%).

Discussions:

The CARE rule safely classified 20% of patients in a very-low risk category, for whom the hypothesis of a NSTEMI would have been ruled-out without the need for a troponin test. An additional 34% patients were safely classified in the low risk group according to the HEART score, on the basis of a single troponin test.

Limitations:

This was an observational study. Physicians were not aware of the strategy interpretation and they may have a different and more prudent assessment of CARE items if they were asked to apply the rule. The reduction in terms of troponin tests is theoretical and likely overestimated. Nevertheless, this testifies to the potential medico-economic benefit of the procedure.

Conclusions:

With a very low risk of MACE during follow-up, the CARE Rule and the CARE-HEART strategy may safely allow reduction of troponin measurements in patients presenting to the Emergency Department with chest pain.

15:10 - 15:20 #18296 - OP118 A NICE combination predicting hospitalisation at triage: a European multicentre prospective observational study of febrile children presenting to the Emergency Department.
OP118 A NICE combination predicting hospitalisation at triage: a European multicentre prospective observational study of febrile children presenting to the Emergency Department.

Background and aims:

A large proportion of paediatric Emergency Department (ED) visits consists of febrile children. A prolonged process between arrival at the ED and hospital admission can negatively influence ED crowding and subsequent quality of care for the individual patient. 

While several studies have focused on predicting hospital admission, many of those either focused on adults, on specific diseases (e.g. asthma only) or were performed in a single setting, thus limiting the generalizability of the result to other settings with a different case mix and different admission rates. Furthermore, many models included variables that were not available at triage, such as laboratory results.

We aimed to investigate early risk factors for hospital admission in febrile children attending different EDs in Europe, and to develop and validate a prediction model identifying those children needing hospitalisation, thereby improving patient flow and quality of care.

 

Methods:

In the MOFICHE study (Management and Outcome of Fever in children in Europe, January 2017-April 2018) data were collected on febrile children aged 0–18 years presenting to 12 European. MOFICHE is part of the PERFORM study (http://www.perform2020.eu). Routine data were prospectively collected and included general patient characteristics, markers of disease severity (abnormal vital signs according to the APLS reference ranges, Paediatric Early Warning Score (PEWS) and NICE fever guideline red alarming signs) and disposition (discharge, admission, ICU admission). 
A prediction model for hospitalisation was constructed using multivariable logistic regression analysis. We used a stepwise approach in which models with general patient characteristics, vital signs, PEWS and NICE alarming signs were tested separately, and were subsequently combined in the final model. The prediction model was derived in a random sample of half of the cases and validated in the remaining set. We determined the discriminative value of the model by calculating the receiver operating curves (ROCs) and assessed the predictive performance (sensitivity, specificity) at a high specificity level as our aim was to identify children at high risk for admission. 

 

Results:

38,496 children were included. Of those, 13.397 (34,9%) children were admitted to a general ward and 156 to the ICU. 
When testing patient characteristics and markers of disease severity separately, only the NICE alarming signs performed well with an AUC of 0.77 (95% CI 0.77-0.77), while patient characteristics, vital signs and PEWS performed poorly (AUC’s all below <0.70). 

However, combining patient characteristics, vital signs and NICE alarming signs yielded an AUC of 0.82 (95% CI 0.82-0.82). The model performed equally well in the validation set.
A “rule-in model” was created, which was highly specific (95%) with low sensitivity (37%), a positive likelihood ratio of 7.5 and a positive predictive value of 72%.

A digital calculator was constructed to facilitate clinical use.

 

Conclusion:

The combination of patient characteristics and markers of disease severity available at triage can be used to identify children at high risk for hospitalisation at an early stage and improve ED patient flow.

15:20 - 15:30 #18493 - OP119 A randomised, double-blind, placebo controlled trial of ondansetron to reduce vomiting in children receiving intranasal fentanyl and nitrous oxide for procedural sedation and analgesia.
OP119 A randomised, double-blind, placebo controlled trial of ondansetron to reduce vomiting in children receiving intranasal fentanyl and nitrous oxide for procedural sedation and analgesia.

Background:

Intranasal fentanyl and nitrous oxide are frequently combined for procedural sedation and analgesia in children. This approach is advantageous for its non-parenteral administration, but is associated with a higher incidence of vomiting than nitrous nitrous used as a sole agent. We sought to assess whether the preprocedural use of ondansetron reduces the incidence of vomiting associated with the combination of intranasal fentanyl and nitrous oxide for procedural sedation compared with placebo.

 Methods:

This was a double-blind, randomised, placebo controlled superiority trial conducted between October 2016 and January 2019 at a single tertiary care paediatric emergency department. Eligible patients were children aged 3-18 years with planned sedation with intranasal fentanyl and nitrous oxide. Participants were randomised to receive ondansetron or placebo 30-60 minutes prior to nitrous oxide administration. The primary outcome was early vomiting associated with procedural sedation defined as occuring during or up to 1 hour after nitrous oxide administration. Secondary outcomes were: number of vomits and retching during procedural sedation, vomiting 1 to 24 hours post procedural sedation, procedural sedation duration, adverse events and quality of sedation across the two groups.

 

Results:

442 participants were randomised and outcome data were available for analysis in 436 participants. There was little evidence of a difference in the primary outcome, early vomiting associated with procedural sedation, between the groups: ondansetron 12% vs. placebo 16%, difference in proportions -4.6% (95% confidence interval [CI] -11 to 2.0; P=.18). However, the overall vomiting incidence up to 24 hours after the procedure was lower in ondansetron treated patients 21% vs. placebo 31% (-10%, 95%CI -19 to -1.4; P=.02), number needed to treat of 10. All other secondary outcomes were similar between the groups. Most sedations were reported as optimal by the treating clinician (91%). There were only two minor adverse events, both in the placebo group. There were no serious adverse events.

 

Discussion & Conclusions:

This is the first study reporting on premedication to prevent vomiting associated with the combination of intranasal fentanyl and nitrous oxide for procedural sedation in children. In this trial, the incidence of early vomiting was lower than previously reported in the literature, which may explain our null findings. We found little evidence that ondansetron reduces the incidence of early vomiting related to procedural sedation with the combination of intranasal fentanyl and nitrous oxide. This trial adds further evidence regarding safety of this sedation strategy.

15:30 - 15:40 #18769 - OP120 Clinical prediction to target new biomarkers in febrile children at the ED, a European observational study.
OP120 Clinical prediction to target new biomarkers in febrile children at the ED, a European observational study.

Background: Early detection and treatment of invasive bacterial infections reduces morbidity and mortality. Distinguishing between invasive bacterial and self-limiting viral infections solely based on clinical signs and symptoms is unreliable. Therefore, overtreatment with antibiotics in febrile illnesses is common. In Europe, antibiotic prescription rates for febrile illness vary from 19% to 64%.

Aim: To externally validate and update a clinical prediction model to identify invasive bacterial infections and define risk thresholds where new biomarkers could improve accurate diagnosis.

Methods: Data of febrile children <18 years attending 12 European EDs were collected between January 2017-April 2018. The main outcome measure was invasive bacterial infection (IBI) defined as bacteremia, sepsis or bacterial meningitis. For this analysis, we excluded children without C-reactive protein (CRP) measurement and children with urinary tract infection. We externally validated and updated an existing clinical prediction model (Feverkidstool which includes vital signs, clinical symptoms and CRP) and extended the model by including level of consciousness. We determined the discriminative value by the C-statistic and assessed the predictive performance (sensitivity, specificity, negative and positive likelihood ratios) at different thresholds.

Results: 16,225 patients were included (median age 2.8 years (IQR 1.4-6.0), 29% ill appearing) of whom 155 had an IBI. The discriminative ability of IBI versus no IBI was moderate for the original model (0.73 (95% CI 0.69-0.77) and improved in the updated model with consciousness (0.79 (95% CI 0.75-0.83). The updated model for IBI performed well for the low-risk threshold of 2.5% (sensitivity 0.93 (95% CI 0.86-0.97), negative likelihood ratio 0.39 (95% CI 0.2-0.8)) and was moderate for the high-risk threshold of 30% (specificity 0.88 (95 % CI 0.87-0.89), positive likelihood ratio 3.5 (95% CI 2.7-4.6). The intermediate thresholds of 5-30% performed poorly (ranges: sensitivity 0.58-0.85, negative likelihood ratio 0.46-0.59, specificity 0.33-0.71, positive likelihood ratio 1.26-1.99).

Conclusion: The low-risk threshold of the updated clinical prediction model is useful to rule- out patients with IBI at the ED. The intermediate and high-risk thresholds are lacking excellent rule-in value for IBI to target treatment. The number of unnecessary treated patients could potentially be reduced by addition of other new sensitive biomarkers.

14:10 - 14:20 #19093 - OP046 The impact of dispatcher assistance in the rates and efficacy of bystander cardiopulmonary resuscitation: A meta-analysis.
OP046 The impact of dispatcher assistance in the rates and efficacy of bystander cardiopulmonary resuscitation: A meta-analysis.

Objectives The introduction and development of the concept of emergency medical services (EMS) has played a crucial role in decreasing mortality rates and returning to independent survival in out-of-hospital cardiac arrests(OHCA). The role of Dispatcher Assisted Cardiopulmonary Resuscitation (DACPR) has not been widely reported. The objectives of the study were to perform a meta-analysis of observational studies addressing whether DACPR, compared with independent Bystander Cardiopulmonary Resuscitation (BCPR),increased the rates of BCPR, and whether they altered survival outcomes compared with no BCPR in OHCA.

Methods We searched the relevant literature from PubMed and Cochrane databases. The basic information and outcome data (BCPR rates, survival to hospital discharge, 1-month survival) were extracted from the included studies. Meta-analyses were performed by using STATA 11.0 software.

Results Eight studies involving 65,148 patients were eligible. Overall meta-analysis showed that DACPR was associated with statistically improved rates of BCPR (Odds Ratio [OR] =3.48, 95% confidence interval[CI]: 2.08-5.83, I2= 96.7%), and survival to discharge/ 1-month survival (OR=1.51, 95%CI: 1.40-1.63, I2= 24.9%) when compared with no BCPR.However, no significant effect of DACPR in survival rate was found, when compared with independent BCPR (OR=0.84, 95% CI: 0.62-1.14, I2= 88.6%).

Conclusion This study found that DACPR resulted in significantly higher rates of BCPR as compared withindependentBCPRin OHCAs.Considering that DACPR also resulted in greater survival rate compared withno BCPR,DACPR should be a standard protocol for EMS systems worldwide.

OP047 Degeneration of Shockable Rhythm According to the No-flow Time for Out-of-Hospital Cardiac Arrest Patients.

Background

Patients for whom the out-of-hospital cardiac arrest (OHCA) is not witnessed are generally not considered eligible for extracorporeal resuscitation (E-CPR) because the duration before the initiation of their resuscitation (no-flow) is uncertain. It has previously been proposed that an initial shockable rhythm (SR) strongly suggested a short period of no-flow. The objective of this study was to describe the association between the duration between the initiation of the prehospital resuscitation and the presence of a SR for patients suffering from an OHCA.

Methods

The present cohort study used a registry of adult OHCA between 2010 and 2015 in Montreal, Canada. Adult patients suffering from a non-traumatic OHCA for whom the OHCA was witnessed, who did not have by-stander cardiopulmonary resuscitation were included. Patients who had a paramedic-witnessed OHCA were also included as a control group (no-flow time = 0 minutes). Patients who experienced a return of spontaneous circulation (ROSC) before the paramedics’ arrival or for whom the initial rhythm was not known were excluded. The evolution of the proportion of SR was initially described and a multivariable logistic regression controlling for pertinent demographic and clinical variables (e.g. age, gender, time of the day).

Results

A total of 1751 patients (male = 67%, mean age = 69 years [standard deviation = 16]) were included in the main analysis, of whom 603 (34%) had an initial shockable rhythm. A total of 663 other patients had their OHCA witnessed by paramedics. A shorter no-flow duration was associated with the presence of an initial SR (adjusted odds ratio = 0.97 [95% confidence interval = 0.94-0.99], p=0.016). However, this relation was not linear and the proportion of SR does not seem to lower until 15 minutes of no-flow duration (0 min = 35%, 1-5 min = 37%, 5-10 min = 35%, 10-15 min = 34%, more than 15 min = 16%).

Conclusion

Although the proportion of patients with a SR decreases as the no-flow duration increase, this relationship does not appear to be linear. The main decline in the proportion of patients with SR seems to occur after the fifteenth minute of no-flow time.

14:30 - 14:40 #18370 - OP048 Urban-Rural gap in Effectiveness of Dispatcher-Assisted Cardiopulmonary Resuscitation.
OP048 Urban-Rural gap in Effectiveness of Dispatcher-Assisted Cardiopulmonary Resuscitation.

Background:

  Out-of-hospital cardiac arrest (OHCA) is the leading cause of death worldwide. Dispatcher-assisted cardiopulmonary resuscitation (DACPR) is an effective intervention to promote early bystander CPR and improve survival outcome in patients with OHCA. The different effectiveness of implementing DACPR in urban and rural areas has not been explored.

Methods:

  This is a prospective observational study. It was carried out in Taichung County, which is consisted with urban, suburban and rural areas. In 2018, Taichung had more than 2.8 million residents and more than 2500 patients with OHCA. We have been promoting DACPR since 2015. All dispatchers have received at least 8-hour training on providing DACPR instructions. After two years of running-in, DACPR was implemented steadily in Taichung.

  All OHCA cases occurred in Taichung County from July 1, 2017 to November 30, 2018 were included in the study. Those appeared apparent death, refused hospital referral, aged younger than 20 years and those who with cardiac arrest consecutive to trauma were excluded. Those who lacked audio file records were also excluded. Prehospital data were collected according to the Utstein-style template. The primary outcome of this study was to determine the urban-rural gap in the proportion of bystander performed CPR after dispatchers identified cardiac arrest status. Patient’s outcome, such as return of spontaneous circulation (ROSC) before hospital arrival, 2-hour survival rate, and neurological outcomes were also recorded.

 

Results

  A total of 2716 patients were enrolled in this study after excluded those who met the aforementioned exclusion criteria. Patients with OHCA in the rural areas were older than urban areas (71.0±16.4 in urban areas, 69.68±15.8 in suburban areas, and 73.03±14.9 in rural areas respectively, p = 0.006). When compared with urban areas, emergency medical services response time was increased in rural areas. There was no difference in gender, types of location where cardiac arrest occurred, witness of arrests and initial shockable arrests.

  There was no difference in the recognition of cardiac arrest between urban and rural areas. However, after the dispatchers identified cardiac arrests, the proportion of bystanders who performed CPR in urban areas is higher than in rural areas (75.87% in urban areas, 73.46% in suburban areas and 67.73% in rural areas). The urban area has a relatively higher chance to achieve ROSC, and has a relatively higher proportion patients survived with favorable neurological function, but those had not reached statistical significance.

 

Conclusion

The study found that in the same dispatch center, bystanders in urban areas had a higher rate of acceptance and perform of cardiopulmonary resuscitation. Although no statistically significance, it was found that patients with OHCA in urban areas had a better prognosis. In the future, public health and public education are need to make people more likely to perform cardiopulmonary resuscitation and achieve more bystander cardiopulmonary resuscitation.

14:40 - 14:50 #18530 - OP049 Thrombolysis during resuscitation for out-of-hospital cardiac arrest caused by pulmonary embolism increases 30-day survival: findings from the French National Cardiac Arrest Registry.
OP049 Thrombolysis during resuscitation for out-of-hospital cardiac arrest caused by pulmonary embolism increases 30-day survival: findings from the French National Cardiac Arrest Registry.

Background: Pulmonary embolism (PE) represents 2% to 13% of all causes of out-of-hospital cardiac arrest (OHCA) and is associated with extremely unfavorable prognosis. In PE-related OHCA, inconsistent data showed that thrombolysis during cardiopulmonary resuscitation (CPR) may favor survival.

Methods: It was a retrospective, observational, multicenter study from the French National OHCA. All adult OHCA, managed by a mobile intensive care unit, and with a diagnosis of pulmonary embolism confirmed on hospital admission were included. PE was diagnosed on hospital admission by computed tomography pulmonary angiography (CTPA) (definite PE) or echocardiogram (probable PE). We excluded all other causes of OHCA and patients who had ROSC prior to mobile intensive care unit management. Patients were classified in two groups: those who received thrombolytic therapy during cardiopulmonary resuscitation and those who did not. The primary end point was day-30 survival in a weighted population. In order to obtain unbiased estimations of the average treatment effects, we used inverse probability of treatment weighting (IPTW). This method was performed in two steps: first, an estimation of the propensity score of treatment (thrombolysis during cardiopulmonary resuscitation) with a logistic model, and then an estimation of the effect of treatment on 30-day survival, weighted on the propensity score. The present study was approved by the French Advisory Committee on Information Processing in Health Research (CCTIRS) and the French National Data Protection Commission. It was approved as a medical assessment registry without requirement for patient consent.

Results: From July 2011 to March 2018, of the 14,253 patients admitted to the hospitals, 328 had a final diagnosis of PE and 246 were included in the analysis. In the group that received thrombolysis during resuscitation (n=58), 14 received alteplase (24%), 43 tenecteplase (74%) and 1 streptokinase (2%). Thirty-day survival was higher in the thrombolysis group than in the control group (16% vs 6%, P=0.005; adjusted log-rank test) but the good neurological outcome was no significantly different (10% vs 5%; adjusted relative risk = 1.97 CI95[0.70–5.56]). Median duration of stay in the intensive care unit (ICU) was 1 (0-5) day in the thrombolysis group and 1 (0-3) day in the control group (P=0.23). Mortality on day 0 (i.e., day of the OHCA) was 34% in the thrombolysis group and 37% in the control group (P = 0.76). Among all survivors at day 30, the median time until ICU discharge was 10 (4-21) days. Subjects in the thrombolysis group would not die of hemorrhage any more than those in the control group (6% vs 5%; P = 0.73). On the other hand, irreversible coma appeared slightly less frequent as a cause of death in the thrombolysis group (2% vs 11%; P = 0.05).

Conclusions: In OHCA patients with confirmed PE and admitted with recuperation of spontaneous circulation in the hospital, there was significantly higher 30-day survival in those who received thrombolysis during CPR compared with patients who did not receive thrombolysis. Randomized controlled trials are needed to define the role of thrombolysis in the management of suspected PE-related OHCA.

14:50 - 15:00 #18988 - OP050 Effect of the floor level on a neurologically favorable discharge after cardiac arrest according to the event location.
OP050 Effect of the floor level on a neurologically favorable discharge after cardiac arrest according to the event location.

Background:

Increases in the population concentrations in urban areas have led to increases in the numbers of people who live in high-rise buildings. Several studies reported the negative outcomes of patients who experience OHCA in high-rise buildings. Despite the above findings, we assumed that an increased vertical distance would always lead to a delayed EMS response time, as high-rise buildings tend to be densely populated and located in traffic center. This study aimed to compare the emergency medical service (EMS) response times and probability of a neurologically favorable discharge among patients who suffered an out-of-hospital cardiac arrest (OHCA) while on a high or low floor at home or in a public place.

Methods:

This retrospective analysis was based on Smart Advanced Life Support registry data from January 2016 to December 2017. Patients older than 18 years who suffered an OHCA due to medical causes were included in this study. Patients who were not resuscitated because of obvious signs of death, a refusal of CPR, do-not-resuscitation (DNR) state, or medically directed cessation of CPR; whose CA was witnessed by 911-initiated first responders; or who had incomplete data were excluded. A high floor was defined as the ≥3rd floor above ground. We compared the probability of a neurologically favorable discharge according to the floor level and location (home vs. public place) of the OHCA event. Additionally, we calculated the call-to-scene and call-to-patient times after OHCA for patients classified into the high and low (<3rd) floor groups according to the CA event location.

Results:

Of the 6,335 included OHCA cases, 4,154 (65.6%) events occurred in homes. Rapid call-to-scene times for high floor events were reported in both homes and public places. A longer call-to-patient time was observed for home events. Among OHCA events that occurred on high floors, the likelihood of a neurologically favorable discharge was significantly lower if the event occurred in a public place (adjusted odds ratio [aOR]=0.58) but higher if the event occurred at home (aOR=1.49).

Discussion & Conclusions:

Both the EMS response times to OHCA events in high-rise buildings and the probability of a neurologically favorable discharge differed between homes and public places. The results suggest that the prognosis of an OHCA patient is more likely to be affected by the building structure and use rather than the floor height.

15:00 - 15:10 #19052 - OP051 Implementation of Dispatcher-assisted CPR was associated not only with better survival rates but also with increased number of cardiac arrest patients found by EMS with ventricular fibrillation.
OP051 Implementation of Dispatcher-assisted CPR was associated not only with better survival rates but also with increased number of cardiac arrest patients found by EMS with ventricular fibrillation.

Background

Many studies confirmed that dispatcher-assisted CPR (D-CPR) could improve survival from out-of-hospital cardiac arrest (OHCA) by significant improvement of bystander-CPR (B-CPR) rates. The aim of this study was to confirm relation between D-CPR implementation, incidence of cardiac arrest patients found by EMS with ventricular fibrillation (VF OHCA) and survival from VF OHCA from long-term (15 years) perspective.

Method

This is a retrospective analysis of Prague Utstein-style OHCA registry from the beginning of D-CPR implementation (2003) until the end of 2018. Survival from cardiac arrest was defined as survival with cerebral performance category 1 or 2 during 30 days follow-up after OHCA.

Results

During first ten years of D-CPR implementation, B-CPR rates increased from 13,6%  to 81,0% (p<0,0001) and then remained more or less stable for following 6 years. This process was in strong correlation with VF OHCA incidence (Pearson R score = 0,684; P-Value = 0,003) as well as with VF OHCA survival rate (Pearson R score = 0,782; P-value = 0,00011). 

Conclusion

VF OHCA incidence as well as VF OHCA survival rates were in a strong correlation with D-CPR implementation as measured by B-CPR ratios. This supports the hypothesis that D-CPR increases survival from OHCA not only by improving survival rates, but also by keeping more patients with ventricular fibrillation running until EMS arrival.

15:10 - 15:20 #19153 - OP052 Comparison between emergency physicians’ decision to hospitalize or discharge home and clinical risk categories of the MEESSI scale among patients with acute heart failure.
OP052 Comparison between emergency physicians’ decision to hospitalize or discharge home and clinical risk categories of the MEESSI scale among patients with acute heart failure.

Objective: The MEESSI is a validated clinical decision tool that characterizes risk of mortality in emergency department (ED) acute heart failure (AHF) patients. The objective of this study was to compare the distribution of risk categories between hospitalized and discharged ED patients with AHF.

Methods: We included consecutive AHF patients from 34 Spanish EDs. Patients were retrospectively classified according to MEESSI risk categories. We calculated the odds of hospitalization (vs. direct discharge from the ED) across MEESSI risk categories. Next we assessed the following 30-day post-discharge outcomes: ED revisit, hospitalization, death, and their combination. We used Cox hazards models to determine the adjusted association between ED disposition decision and the outcomes among patients who were stratified into low and increased risk categories.

Results: We included 7,930 patients [age=80.5 (SD=10.1) years; women=54.7%; hospitalized=75.3%]. Compared to low-risk MEESSI patients, OR for hospitalization of patients in intermediate, high and very-high risk categories were 1.83 (1.64-2.05), 3.05 (2.48-3.76) and 3.98 (3.13-5.05), respectively. However, almost half (47.6%) of all discharged patients were categorized as increased risk by MEESSI, and 19.0% of all the increased risk patients were discharged from the ED. Among the low-risk MEESSI patients, the 30-day post-discharge mortality did not differ by ED disposition (HR for discharged patients respect to hospitalized 0.65, 0.70-1.11), nor did it differ in the increased risk group (0.88, CI 0.63-1.23). The low risk MEESSI patients had higher risks of 30-day ED revisit and hospitalization (1.86, 1.57-2.20; and 1.92, 1.54-2.40; respectively) as did the increased risk group (1.62, 1.39-1.89; and 1.40, 1.16-1.68), with similar results for the combined endpoint[MO(1] .

Conclusions: The disposition decisions made in current clinical practice for ED AHF patients calibrate with MEESSI risk categories, but nearly half of the patients currently discharged from the ED fall into increased risk MEESSI categories.

15:20 - 15:30 #19168 - OP053 Evolution of bystander intention to perform cardiopulmonary resuscitation after training : an online survey.
OP053 Evolution of bystander intention to perform cardiopulmonary resuscitation after training : an online survey.

Background:

Early cardiopulmonary resuscitation (CPR) dramatically increases the chances of neurologically intact survival after cardiac arrest. CPR is however initiated by bystanders in less than half of all out-of-hospital cardiac arrests. The probability of starting CPR depends on the intention to perform resuscitation, which can be divided into three components: attitude, perceived norms, and self-efficacy. The aim of our study was to evaluate how these components change according to the time elapsed since the last CPR training.

Method:

After consultation of our local ethics committee, a web-based survey was created. Intention to perform CPR was assessed by 17 questions based on a 4-point Likert scale.

A link to the survey was sent via e-mail by a Red Cross National Society affiliated CPR training centre based in Geneva, Switzerland, to all previous participants for whom an electronic address was available. No personal data other than that required for the demographic analysis was ever recorded or asked for.

After connection to the web site, a consent form and confidentiality statement were immediately displayed.

Surveys were excluded if they were completed by healthcare professionals, healthcare students, or if the last CPR training took place more than five years prior to our study.

Data was stored in an encrypted MySQL database, extracted to a comma-separated value file, and analysed using Stata 15. Participants were sorted in two groups according to their last CPR training (< 1 year and ≥ 1 year). Fisher’s exact test or chi-square test were used according to normality and sample size. A p value < 0.05 was considered significant.

Results:

3360 e-mails were sent at the end of January 2019. 162 surveys were included in our analysis (59 were excluded according to our criteria). There was no significant difference in demographics between the two groups.

Attitude: 5 out of 6 elements did not differ significantly. The ≥ 1 year group was more worried about the risk of contracting a transmissible illness in (p=0.010).

Perceived norms: 5 out of 6 elements did not differ significantly. Participants in the ≥ 1 year group were more prone to the risk of diffusion of responsibility (p=0.011).

Self-efficacy: 2 out of 5 elements did not differ significantly.  Participants in the ≥ 1 year group felt less confident about their ability to recognize a cardiac arrest (p < 0.001) and to perform CPR (p=0.029). They also felt they wouldn’t be helpful if they had to deal with a cardiac arrest (p=0.004).

Conclusion:

After CPR training, elements related to all three components determining the intention to perform CPR decreased significantly over time. This might prevent some bystanders from providing early CPR, and further research should therefore focus on means to prevent, avoid, or compensate this decrease, far beyond technical considerations.

15:30 - 15:40 #19329 - OP054 Peer teaching model for basic life support in high school student.
OP054 Peer teaching model for basic life support in high school student.

Objective: It has been shown that initiation of early cardiopulmonary resuscitation (CPR) decreases morbidity and mortality of out-of-hospital cardiac arrest patients.Despite this information, the rate of early CPR application is low in most countries. Basic life support (BLS) training for the public is important to increase the rate of CPR application in out-of-hospital cardiac arrests. In this study we aimed to test the effectiveness of peer education method on the learning and application of BLS in high school students.

Method: The study was conducted in high school and grade one students were included in the study. Students are divided in two groups (Group A and Group B). Pre-test and post-test tests were applied before and after training to measure the awareness and knowledge of all students.At the beginning of the study pediatric emergency and pediatric intensive care physicians trained eight students in group A.  These eight students were given BLS instructor training.   Afterwards these students trained eight students in group B with same method and those eight students in group B became instructor.  Instructor students from both groups trained their friends in their own group.A medical doctor supervised every training session. Training session was not intervened unless there is wrong information transfer or unanswered question by instructor student.

Results:153 students were included in the study. 5 students were excluded from the study because they did not participate in the tests. There were 76 students in group A and 72 students in group B.There was a statistically significant improvement in 8 questions from 13 questions in the pre- and post-training knowledge tests (p <0.05). Students were able to give true answers regarding environmental safety, consciousness assessment, control of the airway and respiration, 30: 2 chest compression, 100 times chest compression, the hands placed in the middle of the chest. This situation was similar in two groups and there was no difference between two groups in terms of improvement in post-test performance.Students were evaluated in terms of BLS application competence. In the 16-step evaluation, the students in group A applied BLS with a success rate of 90.2% and B group with a success rate of 93.4%. In group A, it was found that the most successful steps were respiration control and performing 30: 2 chest compressions.Calling emergency call center step was the most forgotten step in group A.In Group B, most successful step was to provide environmental safety, the most forgotten step was to call emergency call center.In post-training awareness questionnaire, significant improvement was determined in terms of basic life support (BLS) hearing, understanding of BLS need, feeling sufficient to apply BLS, giving BLS training in schools and watching videos about BLS.

Conclusion:This is the first study testing the effectiveness of peer education method in BLS training of high school students. It was shown that with peer education model students could train other students as basic life support instructors. With the implementation and dissemination of this training model, BLS training can be given to the public much faster.

15:45 - 15:50 #18268 - SP041 Health promotion in emergency departments with a digital tablet: an observational study.
SP041 Health promotion in emergency departments with a digital tablet: an observational study.

Background: In European countries, an increasing number of patients consult the emergency department (ED) instead of a general practitioner for non-urgent primary medical care. These patients may benefit from ED-based preventive care but overloaded ED physicians are reluctant to be involved. The primary objective of this study was to evaluate the proportion of patients accepting a preventive care intervention using a digital tablet (DT) during their ED visits; the secondary objective was to evaluate the proportion of patients benefitting from counselling.

Methods: Single-center observational study conducted in the minor section of a tertiary-care ED in August and September 2018. Inclusion of consecutive patients ≥18 years with decision-making capacity, admitted during the investigator's presence (rotating 8-hour shifts within a 24h/7d schedule). The DT presented a menu of nine validated health questionnaires with, after completion, a personalized report with health recommendations based on individual scores, and links to support material or details of specialized services. The report could be printed or emailed to the patient.

Results presented as proportions, mean and standard deviation (SD) or median and interquartile range (IQR). The ethics committee approved this study.

Results: 500 eligible patients were approached and 317 (63%) included. Median ED length of stay: 5.2h (3.7; 7.6). Mean age: 44 ± 17 years, women: 45%; 98% Swiss residents; 54% professionals and 20% retired; 27% with a postgraduate degree, 83% registered with a GP, of whom 84% had visited at least once in the preceding year. Patients filled a median of 4 (2;9) questionnaires. Questionnaires presented by frequency of choice: 1) physical activity 71%: 55% below the recommendation of ≥2x30 minutes/week of moderate activity; 2) alcohol consumption 62%: 55% at-risk drinkers; 3) 62% tobacco: 53% active smokers and 58% contemplating smoking cessation; 4) diabetes 62%: 14% at high risk of developing diabetes, with 62% accepting a bedside capillary glucose check with one new diabetes diagnosis; 5) vaccination status 60%: 24% not up to date; 6) colon cancer 56%: 26% of those aged 50-69 years never screened by colonoscopy or fecal occult blood testing, and 14% having failed to keep up with screening schedules; 7) HIV 50%: 40% accepting a rapid non-targeted opt-in capillary test; no reactive test;7) interpersonal violence 46%: 21% victims of verbal and/or physical violence, of whom 10% wished to discuss this issue with the ED physician; 9) drug misuse 48%: 35% reporting recent misuse.

Discussion & Conclusions: A majority of patients accepted a digital screening and health-counseling offer, and 50% chose at least four domains. The questionnaires revealed that a significant proportion of this mostly young and active ED population could benefit from advice to improve their health. Although we did not measure the long-term impacts of our intervention, a significant proportion accepted immediate bedside tests for diabetes and HIV. Our results suggest that a DT screening offer would allow the ED to play a complementary role in promoting health in Switzerland. However, further research on its clinical impact is needed before widespread dissemination of this intervention is attempted in Swiss EDs.

SP042 Mass casualty incidents digital transformation - a reloaded project.

Background:

Six years ago a mass casualty incident digitalization project began under the acronym SICAD. The aim of the project was to completely transform the mass casualty incident management on the field and remotely by using current communication technology. This implies using a mobile and server solution as well as electronic patient tags. After a long period of extensive testing of all modules and given several technical drawbacks due to the complexity of the overall solution, a completely redesigned project emerges to carry on the future version of the initial project. The new solution is renamed EMERSYS and it is designed primarily for the use of Romanian emergency agencies.

Methods:

The technical backbone of the previous solution was redesigned in terms of modularity and interconnectivity. Initial requirements for the software solutions are set, allowing for each module to receive and output data independently. The previous Parse.com database integration is completely replaced by an SQL database. Trafficked data is managed by a store-and-forward algorithm in order to maintain a steady flow of operation despite probable moments of lack of data signal. Data logging is significantly augmented. The solution also expands in terms of purpose to several individual applications – mobile and web-based – to address both professionals and bystanders. Improvements are also integrated in terms of power efficiency, graphics, software solution size and operation optimization and security.

Results:

Three distinct packages are set. EMERSYS ONE is an entry level pack designed to digitize the mass casualty incident paper chart and integrate several electronic patient tags. It comprises of a dedicated mobile app for prehospital physicians and paramedics and a web-based app for data output. EMERSYS TWO is a professional pack designed to integrate the majority of functions of the project. It addresses all professionals involved as well as bystanders and it comprises of a dedicated extensive mobile app and six distinct web-based apps: 112 Dispatch, Hospitals, Analysis, Press, Simulator and Backoffice. EMERSYS THREE is based on the same structure as the previous pack but it allows for more advanced algorithms and functions for a more detailed integration of the event digitalization.

Discussion & Conclusions:

The current EMERSYS project carries on the purpose of the previous project to take full advantage of the current technology, especially mobile communications technology. Current work is under way to allow for full offline operation. Further tests are also necessary in order to assess a reliable operation of all packs. Moreover, there is a strong need of simulation by professionals and tech team alike, as well as integrating their feedback. This report refers to the current progress in terms of the overall structure and design and modules operability.

15:55 - 16:00 #18779 - SP043 Needs Assessment for a Pediatric Emergency Medicine Application.
SP043 Needs Assessment for a Pediatric Emergency Medicine Application.

Background: Smartphone applications (apps) have been increasingly utilized by physicians as a tool to supplement and support clinical practice. Barriers to utilization include cost of purchasing the app, user friendliness, lack of specific content, and timeliness of software / content updates. Pediatric Emergency Medicine (PEM) is a specialty that could benefit from a customized mobile app, given nuances in clinical management such as medication dosing or unique age-specific pathology. The purpose of this study was to understand the needs of post-graduate learners as it relates to PEM resources to aid in clinical practice.

Methods: This was a prospective study, and institutional Research Ethics Board approval was obtained. The survey was sent out to all current Emergency Medicine and Pediatrics residents at McMaster University, Canada. Survey questions were related to type of residency, year of training, smartphone and app utilization, and desired content for a new app. For the desired content, participants were requested to list their top 5 items and the responses were then grouped using a theme analysis.  

Results: A total of 35 responses were received (33.7% response rate). 31.4% were from Pediatrics residents, with the remainder from Emergency Medicine. Eighty percent of respondents used Apple’s iOS as their mobile operating system with the remainder using Google’s Android. The top three most commonly used apps were UpToDate (51.4%), MDCalc (42.9%), and Spectrum (22.9%). Spectrum and MDCalc are both free applications available on both platforms, while UpToDate is only offered by paid subscription (whether individually or through an institution).  From the desired topics, the top five themes were related to medication dosing (71.4%), appropriate antibiotic choices (65.7%), treatment algorithms (25.7 %), electrocardiogram (ECG) references (22.9%) and vital sign reference ranges (22.9%).

Conclusion: While there is an abundance of clinical resources available to trainees, mobile apps are a great resource for just-in-time reference. This study provides a starting point to identify what trainees are looking for in an app that is specific to PEM, and can be used to either build a new app or add to an existing one. Further studies would be helpful in understanding the actual utilization of such a resource.

16:00 - 16:05 #19035 - SP044 Improving Emergency Department flow: implementation of consultant based triage in a tertiary university hospital.
SP044 Improving Emergency Department flow: implementation of consultant based triage in a tertiary university hospital.

BACKGROUD

Improving patients flow throughout the Emergency Department(ED) is a desirable goal to reduce overcrowding, morbidity and mortality, and to improve patients and operators satisfaction. Several interventions can be made to reduce the throughput patient flow. Our ED is provided with a rapid assessment area (RAA) after standard first level nurse-led triage. Since November 2018 a senior doctor, so called facilitator, was placed in the RAA. The aim of this study was to compare the waiting-to-be-seen time and ED length of stay (LOS) before and after this intervention.   

METHODS

This is a retrospective cohort study conducted in the ED of the San Martino University Hospital, a tertiary referral centre located in Genoa, Italy, accounting of 90.000 annual visit rates. We analysed data of all ED presentations during 5 months before (from November 2017 to March 2018) and 5 months after (from November 2018 to March 2019) the facilitator implementation. Using our local software, waiting-to-be-seen time (from triage registration to first medical contact) and LOS (from triage to ED discharge) of all patients were analysed. The intervention consisted of the presence of the facilitator in the RAA from Monday to Friday for 6 hours/day meeting the peak demand periods since 1st November 2018. Before this date RAA was nurse-led. His function was to commence a diagnostic and treatment plan then reviewed by other physicians. We analysed the times according to the four-grade priority scale attributed at triage as RAA manage the two middle grade of the scale (yellow and green codes) leaving the higher and lower grade (red and white codes respectively) to other pathway. Ethical approval was not needed as non clinical study. Waiting-to-be-seen time and LOS (in minutes) were normally distributed and compared with Student’s t-test.

RESULTS

We analysed 38.402 and 44.204 ED visits from pre and post-facilitator implementation respectively. Waiting-to-be-seen time for yellow and green codes was reduced of 21,3% (from 103 to 81 min,p<0.05) and of 23,1% (from 157.5 to 121min,p<0.05) respectively. LOS for yellow and green codes was reduced of 23.2% (from 328 to 251.7 min,p<0.05) and of 17.3% (from 303.6 to 250.8min,p<0.05) respectively. Red codes waiting-to-be-seen time increased from 6.6 to 10.6min whilst their LOS reduced from 205,6 to 181min (-17.9%). Similarly white codes waiting-to-be-seen time increased from 120.1 to 122.3 and LOS reduced from 205,6 to 181min and from 197.3 to 172.6 min(-14.6%). 

DISCUSSION & CONCLUSION

We found a reduction of both waiting-to-be-seen time and LOS during facilitator implementation period for yellow and green codes whilst red and white codes didn’t seem to be affected in their waiting-to-be-seen time but we  found a reduction in their LOS. This may be related to a beneficial indirect effect of the facilitator on the other physicians reducing their workload for each patient. Even if many other variables should be taken into account, according to these results facilitator helped to significantly boost ED patients’ process. Management of ED patients flow is an important instrument to reduce overcrowding and further strategies should be sought and implemented.

15:45 - 15:50 #18374 - SP045 Why do patients with renal colic get hospitalised?
SP045 Why do patients with renal colic get hospitalised?

Abstract: Approximately 12% of patients are admitted at their initial emergency department (ED) presentation with renal colic. After revisit this percentage increases to 33%. Currently there is no clinical prediction model that explains the probability of admission. In 2015, a multivariate analysis was published as an impetus for further research. A retrospective cohort study was conducted at the emergency department (ED) of the UZ Brussel, identifying clinical risk factors for hospitalisation. Using clinical parameters, we can only explain half the variance, implying that other factors contribute significantly to hospitalisation in renal colic.

Methods: On the retrospectively collected dataset comprising 1207 ED visits, descriptive statistics via chi-square for categorical and one-way ANOVA for numerical variables were performed. Four binary multivariate logistic regression analyses were used to identify contributing factors to hospitalisation.

Results: On average, hospitalised patients were 5 years older than patients who received outpatient care.  There is also an increased likelihood of hospital admission at revisit, previous history of renal colic, intercurrent urine tract infection, and hydronephrosis. The total equivalents of morphine recieved are 2,9 ± 0,61 mg for outpatients and 11,0 ± 1,18 mg when hospitalised (n = 1207, p <0,001). Overall admission ratios correspond to literature: 12.5% after the first visit and 31.7% on second presentation at the ED. This percentage doesn’t increase with subsequent revisits.

The first multivariate analysis identified the following relevant clinical parameters as contributor to hospitalisation: age, revisits, use of pain score, use of diclofenac, paracetamol, anti-emetics, tamsulosin, morphine equivalents received (Nagelkerke R² = 0.481). The second used radiological stone characteristics (Nagelkerke R² = 0,121). A calculus of <5 mm is a predictor for outpatient treatment, whereas a stone size >20 mm increases likelihood of inpatient treatment, as is hydronephrosis. The location of the calculus in the pyelo-urethral system was not significant. Laboratory results were used in the third analysis. Combination of C-reactive protein (CRP), presence of acute kidney injury (AKI) and a positive urine culture were significant predictors. Total white blood-cell count (WBC) was a non-significant contributor. (Nagelkerke R² = 0.124).  The final model combined all significant predictors from the previous analyses, achieving Nagelkerke R² = 0.51.

Discussion: These results imply that radiological stone characteristics can only explain variation in hospitalisation or outpatient treatment to a limited extent. Combined with the clinical parameters described above, approximately 50% of the variation in admission number can be explained. Most of these parameters are related to analgesic therapy, so analgesic optimisation is of paramount importance. In our opinion the use of diclofenac and paracetamol does not increase hospitalisation probability; Rather, analgesic therapy is improved upon admission.

Conclusion: With hard-clinical parameters only half the variance can be explained, implying that other factors that were not taken into account in this study may contribute significantly to hospitalisation in renal colic.

15:50 - 15:55 #18999 - SP046 PERCEPTION AND MANAGEMENT OF PAIN BY HEALTH PROFESSIONALS IN AN EMERGENCY SERVICE.
SP046 PERCEPTION AND MANAGEMENT OF PAIN BY HEALTH PROFESSIONALS IN AN EMERGENCY SERVICE.

Introduction: Pain is one of the main reasons for consultation in the Emergency Department, reaching 42.8% of patients who require medical assistance.

Objective: To evaluate the perception and management of pain by healthcare professionals in the Emergency Department of the “Hospital Universitario de La Ribera” (Valencia-Spain)

Methodology: A descriptive, prospective and analytical observational study was performed. Data collection was carried out by means of a survey in which respondents were asked about the transmission of information to the patient on aspects related to pain, systems used to categorize pain, knowledge of protocols and their use in fixed and rescue guidelines, their registration, the system used for their evaluation in the patient, the need to prevent pain, the adequacy of pain treatment in the service and the possibility of improving its approach.

A univariate descriptive analysis and an analytical study were carried out in order to explore whether the professional category influenced the perception and management of pain.

Results: 74.25% of the service workers, mostly women, with an average age of 37.013±10.85 years, were interviewed. The most representative group was nurses (52%). The transmission of information to the patient on aspects related to pain refers to being carried out mainly in a non-written form (always 16%, almost always 38.67% and sometimes 28%). The EVA and EVN scales were the most used to categorize pain in the communicative patient (52% and 41.3% respectively). 53.33% of the participants did not use any method to categorize pain in the non-communicative patient. 61.33% know pain control protocols and use them in both fixed and rescue guidelines. Pain is assessed more frequently by asking the patient than by physiological records. 57.3% consider that pain management in the unit is almost always adequate and 44% think it can always be improved.

Analysis by professional categories showed significant differences in the variables need to promote and prevent pain (p=0.048) (higher in the physicians and lower in the auxiliaries), a system used to categorize pain in the communicative patient (p=0,001) (doctors indicated the EVA scale and nurses the EVN scale), pain recording frequency (p=0.016) (nurses refer to always recording pain and doctors some or few times) and pain evaluation frequency asking the patient (p=0.04) (much higher in nursing assistants and lower in doctors).

 

Conclusions:

In the Emergency Department of the “Hospital Universitario de la Ribera” pain assessment and treatment should be improved in order to unify criteria among professional groups and establish a systematic way of dealing with pain according to the type, severity and characteristics of the patient, implementing and using protocols to improve the approach to pain in patients.

SP047 Understanding patient perspectives on informed consent for analgesia research in the Emergency Department.

Background

 

Acute pain is common in emergency patients.  Acute pain management is an important area for research with previous reports highlighting poor pain management impacting negatively on patient experience, but obtaining consent in these circumstances is challenging. For patients experiencing a health emergency, the capacity to make decisions regarding analgesia and to consent to participate in research can be affected by many factors including co-morbidities, stress, emotion and the illness or injury itself. Consent waivers are often granted in seriously compromised patients, but this process is less clear when the patient is conscious but in severe pain. Furthermore, little is known about the patient perspective. 

 

Methods

 

A face to face survey was completed from February to April 2019 in a UK major trauma centre ED by two interviewers. Additional physiological information was collected from the pre-hospital and hospital patient care record. The survey was approved and registered with University Hospitals Plymouth NHS Trust, CA_2018-19-12.

 

Participants were identified through convenience sampling using the inclusion criteria: aged 18 years or over; Glasgow Coma Scale of 15; presented with a traumatic injury or abdominal pain; had been conveyed to hospital by ambulance; and could recall their pre-hospital treatment. Participants provided verbal consent to be interviewed. Bias between interviewers was minimized through set questions. 

 

The primary outcome was to determine if participants felt they could have provided informed consent at set time points. Secondary measures included patient demographics, physiological and pain data, analgesia and patient perspective comments from open questions. 

 

Results 

 

37 participants were surveyed (20 female, 17 male, aged 18 to >85 years). 95% reported past medical problems, 92% were taking one or more regular medications, with 38% on regular analgesia. Abdominal pain made up 78% (n=28) of participants. 

 

87% of respondents received analgesia in the pre-hospital setting. 97% thought that research to improve acute pain management was a good idea. 

 

78% reported that pain was at its worst before receiving pre-hospital analgesia and 13% reported it was worse on transfer to, arrival at or in the ED. Pain scores were not recorded in 2 participants at initial pre-hospital contact, 6 participants following initial analgesia and in 10 participants at ED triage. 

 

Regarding decision-making for written informed consent, 24% felt they couldn’t have provided consent prior to receiving pre-hospital analgesia, which decreased to 11% after initial pain relief and to 5% in the ED. Comments were themed around inability to process, understand and retain information due to pain. 84% reported that they would have been happy to have consent delayed until arrival at the ED; those with concerns reported medical history, drug interactions and allergies as important considerations. 

 

Conclusion

 

Emergency care analgesia research is important to patients, and several factors influence a patient’s perceived ability to provide informed consent including environment, pain and pre-existing conditions. When planning analgesia research, patient involvement is key to determining the informed consent process.

16:00 - 16:05 #19411 - SP048 Procedural sedation and analgesia in a Belgian Emergency Department: an observational cohort study.
SP048 Procedural sedation and analgesia in a Belgian Emergency Department: an observational cohort study.

Aim:

To describe the indications, used medication and safety of procedural sedation in a Belgian University Hospital Emergency Department.

 

Methodes:

We performed a prospective observational cohort study of all patients who underwent procedural sedation and analgesia in a Belgian Emergency Department between April 2017 and April 2018. Standardised forms were used to collect data on patient demographics, indication, performed procedures, used medication and the occurence of adverse events classified by the SIVA adverse event reporting tool.

 

Results:

171 patients were included in the study. Median age was 53 years, 56% were male. 40% of patients were ASA class 1, 37% were ASA class 2 and 22% were class 3 or higher. The majority of the patients underwent procedural sedation for cardioversion (34%), reduction of fractures (30%) or dislocations (26%). Propofol and ketamine were the most frequently used medications. Adverse events occured in 12% of cases, mostly due to apnoea (33%), hypoxia (19%) and emesis (19%). All of the adverse events were transient. None of the patients suffered an adverse outcome.
Logistic regression analysis revealed ASA class 3 or higher as independent risk factor for adverse events (p=0.023).

 

Conclusion:

This Belgian cohort study supports the results of international studies showing that procedural sedation in the emergency department is safe, with a 12% adverse event rate and without occurence of adverse outcomes. In line with previous studies, ASA class 3 or higher was found to be an independent risk factor for advers events.

15:45 - 16:05 #18343 - SP049 Assessment of the validity and reliability of a new triage tool for avalanche mass casualty incidents: the cardiac arrest avalanche triage tool.
SP049 Assessment of the validity and reliability of a new triage tool for avalanche mass casualty incidents: the cardiac arrest avalanche triage tool.

INTRODUCTION: The widely used standard avalanche triage algorithm (Bogle 2010) does not include provision for mass casualty incidents (MCI) nor does it detail the use of extra corporeal membrane oxygenation (ECMO). This study aimed to produce a reliable and validated triage tool for use in avalanche MCI that included updated recommendations for the use of ECMO– the Cardiac Arrest Avalanche Triage Tool (CAAV).

METHODS: The CAAV tool was developed by a focus group of four experts in avalanche rescue. To assess the validity of the tool, four other experts who had never seen the tool used the tool to assigned a triage category to 45 simulated cases and to compare to their own expert opinion. Reliability of the tool among these experts was calculated using the Fleiss test. To assess the accuracy of the tool in a broad population of rescuers an online simulation was given to avalanche rescue providers who were asked to triage 39 simulated cases using the CAAV tool: results were compared to the triage categories given by the four experts.

RESULTS: The CAAV tool is available at www.medstatstudio.com/studies/project.php?pid=19 . When experts used the tool it agreed with their expert opinion in 97% of cases (95% confidence interval: 93% - 99%). Inter-rater reliability for the experts was 0.86. Among the 115 avalanche rescue providers who completed the online simulation, triage assignment using the tool was correct in 63% (95% confidence interval: 57% to 68%). Only 43% of the non-expert participants had accuracy of greater than 80%.

CONCLUSIONS: In this study the CAAV tool showed adequate validity and reliability in expert hands. However, in the broad population of rescuers the tool showed poor accuracy. Further refinement of the tool and simulation testing procedure is clearly necessary before moving towards trials in the field.

15:45 - 16:05 #18723 - SP050 Is being “competent”enough? Emergency department registered nurses’ disaster preparedness as assessed using Benner’s model of clinical competence.
SP050 Is being “competent”enough? Emergency department registered nurses’ disaster preparedness as assessed using Benner’s model of clinical competence.

BACKGROUND

 

Major incidents (MI) occur with little or no warning. During an MI emergency department (ED) registered nurses (RN) are among the first to receive, assess and treat patients. Emergency department RNs’ emergency operating plan (EOP) competencies are crucial in effectively mitigating somatic and psychological afflictions that patients may present to the ED. While previous research has indicated the ED nurses’ disaster competencies are low, little is known about the current state of emergency department registered nurses’ EOP competencies in Sweden.

 

AIM

 

To assess emergency department registered nurses’ EOP competencies.

 

METHOD

 

Study design: A cross sectional online survey was conducted during a six-week period between January and February 2019. Purposive criterion sampling method was utilized in recruiting participants.

Participants:  All registered nurses’ (n ≈ 370) employed at six participating emergency departments in the region of Stockholm, Sweden were included.

A total of 100 questionnaires were completed (response rate = 28%). Competencies were rated utilizing a five-point Likert scale based on Benner’s competence model of clinical competence.

The primary outcome variables are five competencies concerning ED EOPs. 1. Content of the EOP 2. Areas of responsibilities. 3. Differences between decision making processes in the Incident Command System for a major incident vs. non-emergency situations. 4. Hospital levels of preparedness and its significance. 5. Decontamination procedures according to the EOP. Predictor variables included ED experience, education levels and frequency of training.

Data was analyzed using descriptive statistics generating means, standard deviations, frequency counts, and percentages. Kendall’s tau b assessed correlation. A p value of <0.05 was considered significant.

 

RESULTS

 

The majority of nurses (77%) had at least 3-5 years of nursing experience. The overall mean of five combined  competencies was 2.95 or just below “competent” on Benner's model. The primary outcome variables (1-5) means ranged from 2.77- 3.27. (1. “contents of the EOP” (mean 2.77 SD 1.25.), 2: “Areas of responsibilities” (mean 2.8 SD 1,23), 3. “decision making processes in the Incident Command System” (mean 2.88 SD 1.21), 4. “Hospital levels of preparedness and its significance.” (mean 3.27 SD 1.18) and 5. “Decontamination procedures according to the EOP” (mean 3.03 SD 1.29).  The strongest positive correlation (r=0,502 p= 0.01) was between clinical experience and self-assessed levels of competency (range mean 1.2 to 3.80 (< 1 year and > 20 years respectively).

 

CONCLUSION

 

Nurses’ overall competency concerning disaster preparedness is slightly lower than “competent” according to Benner’s competence estimation model. The majority of nurses lack clinical major incident experience. Accruing actual MI experience may be elusive due to the rarity of MI.  The results of this study however indicate that nurses’ disaster competencies may be inadequate. However, results indicate that ED RNs may increase their disaster medicine competencies through clinical experience, training and education.  Due to the relatively small sample size, the results may be generalized in similar settings with caution.

15:45 - 16:05 #19201 - SP051 THE SYNCHRONY AND SYNERGY BETWEEN PHYSICIAN AND NURSE IMPROVES THE EVALUATION OF THE BED SURGE CAPACITY. EXPERIENCE OF AN ITALIAN DEA-TRAUMA CENTER.
SP051 THE SYNCHRONY AND SYNERGY BETWEEN PHYSICIAN AND NURSE IMPROVES THE EVALUATION OF THE BED SURGE CAPACITY. EXPERIENCE OF AN ITALIAN DEA-TRAUMA CENTER.

Introduction: The Bed Surge Capacity is a very important information in the articulation of all phases of the PEIMAF inside the hospital as the pre-hospital organization. It derives the importance of a more precise and timely detection.

Purpose: To evaluate the accuracy of the bed surge capacity in eighteen hospital departments and the surgical availability of the three DEA, through the real-time detection of the number of beds available/readily deliverable at 2 and 24 h from a hypothetical maxiemergency, through four total simulations (three with regard to phase 1 and one for phase 2) both consist of two detection times (T2 and T24). In particular, we analyzed the accuracy of information when obtained from physicians, nurses individually or from integrated surveys.

Materials and methods: The estimation of hospitalization and surgical capacity of the foundation has been assessed on weekdays and holidays, dividing the beds free/readily deliverable by typology (medicines, surgeries, intensive care and subintensives) and Availability of operating theatres.

The creation of new beds was presumed by the possibility of displacement of patients in a lower level of care than that provided at the time of detection, dislocation of patients in a discharge room with assistance of type Nursing, transfer to hospitals with less intensity and rehabilitation facilities or discharge at home.

Results: While in the operative phase of Phase 1 only the nursing coordinators were involved, in the study phase were enrolled both doctors and nurses, with a greater involvement of the second in the first surveys, 11 Nurses in the first day of the I simulation, to then decrease numerically up to a single IC involved in the last two surveys, as it indicates the development of more attention by the medical staff to the simulation.

It has been noted an increase in the total percentage of patients who could be discharged in case of emergency, passing from 22% T2 of the I simulation to 29% of T24 of the simulation II. The increase of patients in this category in the course of the study is reflected in the fact that in the I and III evaluation, in which an equal number of physicians and nurses have been involved in T2 and T24, there is no significant variation in the percentage between the two Detection times, but they are relevant if the average of the I and III simulation is taken into account (22% versus 27%) With evidence of a 5% increase in the category..

Conclusions: From this preliminary data it can be said that to have a complete indication of the possibility of transfer of the patient, it is necessary to take into consideration both the criteria of medical and nursing, for which the choice must be made in team Medical/Nursing.

The first are more focused on severity pathology, progress of the diagnostic-therapeutic pathway, hemodynamic stability of the patient, the second focalise patient care needs (autonomy, presence of invasive devices, catheters, Principals of O2 Administration). Analytical comparison studies are required for the confirmation of the data.

15:45 - 16:05 #19421 - SP052 The August 24th, 2016 Central Italy Earthquake: validation of the “Modified Utstein Template for Hospital Disaster Response Reporting” as a new tool for reporting hospital's reaction to disasters.
SP052 The August 24th, 2016 Central Italy Earthquake: validation of the “Modified Utstein Template for Hospital Disaster Response Reporting” as a new tool for reporting hospital's reaction to disasters.

Introduction: after action reports analyze events and improve knowledge about how to prevent and react to unexpected situations. Anyway, there is no consensus among the templates developed for disaster events reporting and there is not a specific model for reporting hospital disaster response.

Hypothesis: we intended to pilot the use of a new assessment tool for hospital response to natural disasters.

Methods: a data collection tool, focused on hospital disaster response to natural disasters, was created modifying the “Utstein-Style Template for Uniform Data Reporting of Acute Medical Response in Disasters” and tested the reaction of the nearest hospitals to the epicenter after the August 24th, 2016 Central Italy earthquake.

Results: 4 hospitals were included. The completion rate of the tool was of 97.10%. A total of 613 patients accessed the four emergency departments, most of them in Rieti hospital (178; 29.04%). Three hundred and thirty – six patients were classified as earthquake-related (54.81%), most of which with trauma injuries (260; 77.38%).

Discussion: this collection tool proved to be feasible and allowed to retrospectively reconstruct most (97.10%) of the steps of hospital disaster plan deployment and response. Details about activation, patients fluxes, times and actions undertaken were easily reconstructed throughout in-field interviews of hospitals’ managers and consulting patients’ charts. The influx of patients appeared to be quite uniformly distributed across the 4 facilities and, according to our data, hospitals’ capabilities were sufficient to resist the surge.

Conclusions: the Modified Utstein Template for Hospital Disaster Response Reporting is a valid instrument for hospital disaster management reporting. This template could be used for a better comprehension of hospital disaster reaction, debriefing activities, and HDP revisions.

15:45 - 15:50 #18527 - SP053 Patterns of abuse in elderly – an underestimated problem at the emergency department.
SP053 Patterns of abuse in elderly – an underestimated problem at the emergency department.

Background: One of the first articles concerning elder abuse was published in 1975. Since then there has been a growing awareness concerning the topic, but there is still a big gap between research and how these findings should be implemented in clinical practice. Medical settings, such as an emergency department (ED), have a potential to be a good location to identify elder abuse because many elderly individuals that have been exposed to abuse need medical expertise to treat their injuries. The main objective of this study was to examine frequency, risk factors and injury patterns of elderly individuals who received care at an emergency department after being a victim to physical abuse.

Methods: The study was conducted as a descriptive, retrospective study where data were collected from medical records during 2011-2012 at Helsingborg General Hospital in the south of Sweden. All patients aged 65 years and above that was seen in the ED were identified and then all patients with the main complaint abuse were included in the study. After all cases of abuse against elderly were identified the medical records for these patients were examined thoroughly to abstract data. Demographic variables such as age, gender and marital status were collected from medical records. Other known risk factors such as psychiatric illness, dementia, stroke and alcohol abuse were registered. Place of injury, if the victim knew the perpetrator, injury patterns and body location, photo documentation of the injuries and if the assault was reported to the police was also abstracted.

Results:  During the study period a total of 39,312 patients ≥ 65 years received care at the ED of Helsingborg General Hospital. Out of those 21 cases of elderly abuse was identified. Several patients had numerous injuries allocated to different body locations. Haematomas were the most frequently documented injury and the head and neck region was the region mostly affected. Some patients showed old scars and haematomas of different ages during the physical examination. Found risk factors were excessive alcohol consumption and comorbidities.

None of the victims had any documented follow-up plan related to the assault.

Conclusion: Statistics from Sweden reports that 13-16 % of all elderly have been victims to some kind of abuse. Even though there has been an increase in research concerning abuse against elderly in the last decades, challenges to identify and intervene against maltreated elderly remains. A large material was used for this study still very few cases of elder abuse was identified, part of this low number can be due to the inclusion criteria and more research is needed. Still there is not enough knowledge concerning elder abuse in Sweden and therefore medical staff face serious problems to recognize and treat these patients at an ED.

Next important step to improve the situation for this patient group would be to introduce a screening tool to identify more persons at risk and develop a follow-up program so that these patients are not left destitute.

15:50 - 15:55 #18569 - SP054 Triage urgency and frailty as predictors of early mortality in older patients in the emergency department: a prospective follow-up study.
SP054 Triage urgency and frailty as predictors of early mortality in older patients in the emergency department: a prospective follow-up study.

Background
Adequate disease specific emergency department (ED) treatment begins with adequate triage to establish urgency and reduce early mortality. Triage in older patients can be challenging due to the presence of multimorbidity, atypical presentation of complaints or the presence of frailty. Our aim was to study the association between disease specific urgency and early mortality in older patients and to study whether the presence of frailty affects this association.

Methods
This was a secondary analysis of the observational multicentre Acutely Presenting Older Patient (APOP) study, in which ED patients aged ≥70 years were prospectively included. Patients were triaged using the Manchester Triage System (MTS) at presentation. Frailty screening was performed using the APOP-screener, which can be administered within 2 minutes at presentation. The primary outcome was 30-day mortality. We assessed whether prediction of mortality was more accurate when frailty was added to MTS by calculating Nagelkerke R² for both models.

Results
We included 2629 ED patients with a median age of 79 (IQR 74-84) years of whom 521 (20.0%) patients were frail according to the APOP screener. Patients were assigned as non-urgent (‘green’, N=717, 27.3%), urgent (‘yellow’, N=1534, 58.3%) and very urgent (‘orange’, N=378, 14.4%). In total 135 (5.1%) patients died within 30 days: 24 (3.3%) non-urgent patients, 84 (5.5%) urgent patients and 27 (7.1%) very urgent patients. Overall, the 30-day mortality rate was higher in frail patients compared to non-frail patients (11.7% vs. 3.4%, p<0.001). This difference was significant within all triage categories. The explained variance of the association between triage and 30-day mortality was higher when in addition to MTS alone (R² 0.009) patients were also screened with the APOP screener (combined R² 0.062).

Conclusion
Combining a frailty measure with the current triage tool improves prediction of early mortality in older ED patients. Adding frailty screening to the routine triage process may help deliver appropriate care to acutely ill older patients.

SP055 Feasibility of screening with the acutely presenting older patient (APOP) screener in routine emergency department care: a feasibility study.

Background
Frailty screening of older patients in the emergency department (ED) is rarely successfully implemented in routine care. The aim of this study was to evaluate feasibility of screening using the recently validated Acutely Presenting Older Patient (APOP) screener, which identifies older ED patients at highest risk of adverse outcomes within two minutes at presentation.

Methods
This two months’ prospective observational cohort study started after implementation of the APOP screener in ED procedures of the Leiden University Medical Center (LUMC). All consecutive patients aged ≥70 years presenting to the ED were included. The main outcome was adherence to screening by triage-nurses, operationalised by the screening rate. We identified determinants of screening omission by assessing patient-, disease- and organizational related factors. Next to this, feedback of triage-nurses on barriers and facilitators of screening adherence was collected with questionnaires.

Results
In total 986 older patients were included, of which 566 (57.4%) were screened. The screening rate was stable over time. A younger age (OR 1.03 (95%CI 1.01-1.06), p=0.018), triage category “red” (OR 0.14 (95%CI 0.04-0.43), p=0.001) and crowding (>14 ED patients upon arrival) (OR 0.65 (95%CI 0.47-0.88), p=0.005) were independent determinants of screening omission. In line, the most important barriers for screening adherence according to triage-nurses were patient- (“patient was too ill”) and organizational factors (“ED was too busy”).

Conclusion
Screening older patients in routine ED care with the APOP screener was feasible. Since adherence to screening was related to patient and organizational factors, attention for these both aspects could improve implementation.

SP056 Quality of life among acutely admitted elderly with and without homecare - A cross sectional study.

Introduction

In Denmark (2017) out of 600.000 yearly hospital admissions of elderly ≥ 65 year, 77.5% were acute. Acute admitted elderly who are dependent on homecare may be especially challenged. Nuanced knowledge about their quality of life (QoL) is limited. The aim of this study is to investigate the difference in ratings and definition of QoL between acutely admitted patients ≥ 65 years, with and without homecare.

Methods

A cross sectional study is in progress at three Danish emergency departments (ED). Acutely admitted cognitively well-functioning patients ≥ 65 are invited from August 2018 and interviewed during their admission. The primary outcome is QoL measured by the questionnaire Schedule for the Evaluation of Individual Quality of Life – Direct Weighting (SEIQoL-DW) (scale 0-100). In order to determine their QoL, the patients select and rate the five most important areas of their QoL. In addition, length of stay and hours of received homecare per week are collected from their medical records.

Linear regression analyses will be used to test the associations between homecare (≥ 2 hours per week) and QoL. The most important areas selected and defined by the patients will be described qualitatively. The areas will be condensed into themes to find the participants overall definition of QoL. Difference in QoL between the groups will be tested by un-paired t-test.

A sample size calculation for two-sample means test, level of significance 95%, power 80% and with 10 percent difference in QoL score between the two groups showed that 406 participants is required.

Results

At present, 297 participants are included in the study and 28% of them receive homecare. Mean age is 76 years (min 65 – max 96), 46% are male and 42% of the participants are living alone. Median length of stay is 41 hours (Interquartile range (IQR): 22 – 86) and 63% of the participants are discharged from the ED. Median QoL score is 81.9 (IQR: 70.0 - 90.3) and areas of importance for the patients QoL so far are; family, friends, neighbours, freedom, activities, and health. The time required to complete SEIQoL-DW is 30 min (IQR: 27-35). The inclusion is expected to be completed in June 2019 and analyses on the full data set will be ready in October.

Conclusion

This study is ongoing. The authors expect that a patient perspective on QoL can provide nuanced knowledge on QoL among acutely admitted patients and to be able to detect association between QoL and dependence on homecare.  Aspects that define individual QoL among patients receiving homecare can be used to develop a guide about the most important priorities and adjustments in nursing care and discharge procedures regarding this fragile population.

15:45 - 15:50 #18422 - SP057 Non-urgent calls to the ambulance service: why do people call and what advice they are given?
SP057 Non-urgent calls to the ambulance service: why do people call and what advice they are given?

Background

In England, approximately 10% of patients who contact the ambulance service are triaged as having low urgency health problems which may not necessitate an ambulance response. These patients often receive clinical advice by telephone instead of an ambulance being sent. This has potential to reduce pressure on ambulance service resources and, in doing so, free up ambulance responses for more urgent cases. A recent study  used linked ambulance and other health event data to identify what happens to patients following the decision to give clinical telephone advice and this identified low rates of hospital admissions (2.5% -10.5%) and deaths (0.006%-0.24%) (within 3 days of receiving ambulance telephone advice). This analysis builds on this research to identify why these patients called the ambulance service and what clinical advice they received. 

Methods

Using the same patient population as the previous study (n=2521 patients who received clinical telephone advice from the ambulance service and whose data was linked to other health event data through the Prehospital Outcomes for Evidence Based Evaluation, PhOEBE study), we obtained additional Advanced Medical Priority Dispatch System (AMPDS) about reason for call (‘what’s the problem’) and clinical telephone advice data from the Telephone Advice Service (TAS). For data linkage purposes, this patient population all had other experiences of contacting the ambulance service. AMPDS and TAS data was linked to the PhOEBE study data using Computer Aided Dispatch (CAD) number (a unique ID for each patient) and date and time was used for verification of the linkage. The additional AMPDS and TAS data obtained for this study was text data, therefore a thematic coding framework was developed to code and categorise the data in order to identify reason for call and clinical advice given.

Results

All newly obtained data was successfully linked to the PhOEBE study data. Using the coding framework, we found that for this low urgency patient population, the most common reason for calling the ambulance service was pain (39.35%). Other reasons included diarrhea/vomiting (11.42%), minor health problems (e.g. wound dressing problems, nosebleeds, catheter issues) (9.12%), mental health, alcohol/drugs or crisis problems (8.45%) and difficulty in breathing (8.57%). A paramedic or nurse advised patients what to do next. Most patients were advised to seek in-hours GP care (27.6%) or to self-care (21.4%). 17.9% were advised to seek out-of-hours urgent care and 9.3% were advised to attend ED.

Conclusion

Some callers seek emergency care for low urgency health problems and ambulance services are developing ways to respond to these calls in a more cost efficient way.  Given that most patients were advised primary care or self-care following ambulance telephone advice, and that low subsequent event rates were identified in the previous study, this indicates that telephone advice for low urgency ambulance service callers is largely safe, and has the potential to ensure resources are available for patients with more urgent health problems. Further work is required to understand whether telephone advice is acceptable to patients.

15:50 - 15:55 #18768 - SP058 The ideal urgent and emergency care system: a qualitative study of public perspectives.
SP058 The ideal urgent and emergency care system: a qualitative study of public perspectives.

Background

It is well documented that large numbers of people seek help for their healthcare needs in secondary emergency care services, such as Emergency Departments (ED) and the ambulance service, when they could have been treated much closer to home. This is putting increased strain on already overstretched and costly urgent and emergency care (UEC) services, which is unsustainable in the long term.

There is an increasing body of literature that has focused on asking patients how they use UEC services with the intention of identifying the reasons for this behaviour. Other studies have described factors that appear to influence patient satisfaction with UEC services. Whilst informative, these studies do not take into consideration what it is that patients actually want from the UEC system. As a result, services are often implemented without consulting the people who will directly benefit from them. The aim of our study was to discuss patient experiences of accessing UEC services and then identify from the patient perspective, what an ideal UEC system would look like.

Methods

Members of the public in a large English city (population >720,000) were invited to participate in focus groups using a purposeful sampling technique, between September and December 2018. To be eligible to participate, participants must have been in contact with a UEC service (ambulance, walk-in centre, ED, Minor Injuries Unit, out-of-hours GP or NHS111) within the last 12 months and stratified into at least one of the following cohorts: (1) working age (

Results

Four workshops were undertaken with 30 members of the public. Respondents were diverse representing each of the four cohorts. The ideas generated by participants centred around three themes: (1) greater communication from health professionals; (2) linked medical records to ensure consistency of care across the UEC system; (3) a more simplified UEC system which is easier to navigate and access. These ideas were directly influenced by participants past experiences of accessing UEC services, whereby they attempted to identify solutions to the problems they commonly encounter.

Conclusion

This is the first study documenting members of the public’s views of what their ideal UEC system would look like. Participants agreed that services need to work more closely together to provide a more efficient and joined up service. This requires greater communication between health professionals, particularly in relation to discharging patients back into community services. Centralised medical records accessible to all services should be seen as priority. This will ensure continuity of care for patients across the whole healthcare system. Additionally, clarity around what UEC services are available locally, what health conditions are appropriate for these and how people can refer into these services are also important.

16:00 - 16:05 #18861 - SP060 Increasing use of EMS by the elderly and patients with non-specific diagnoses.
SP060 Increasing use of EMS by the elderly and patients with non-specific diagnoses.

Background

The use of emergency ambulances has been increasing in recent years. Emergency medical services (EMS) and EMS research primarily focus on time-critical conditions such as cardiac arrest, respiratory failure, myocardial infarction, stroke and severe trauma – the “first hour quintet”. Little is known about the entire EMS patient population in terms of age profiles, the diagnostic pattern and changes over time.

 

Aim

We aimed to investigate changes in age profiles and hospital diagnoses among EMS patients from 2007 to 2018. 

 

Methods

Population-based historic cohort study including EMS patients in the North Denmark Region during 2007, 2014 and 2018. Ambulance data was retrieved from prehospital electronic medical record and data on hospital diagnoses according to International Classification of Diseases (ICD-10) from the regional patient administrative system. We performed descriptive statistics to report the results as frequencies and percentages.

 

Results

The overall number of EMS patients with hospital contacts increased: 14 551 in 2007, 23 928 in 2014 and 26 560 in 2018, corresponding to an 80% increase. Especially the older age groups (65+) increased in number and fraction from 4 781/32.9% in 2007, to 9 995/41.8% in 2014 and finally 11 980/45.1% in 2018.  Likewise, from 2007 to 2018, non-specific diagnoses increased from 3 993/27% to 10 183/39%. Injuries increased in numbers from 4 999 to 6 537, but decreased in fraction from 34 % to 25 %. Cardio-vascular and respiratory diseases increased in numbers (1 450 to 3 088 and 883 to 2 098) but fractions remained largely unchanged. Finally, psychiatric disease/substance abuse decreased in fraction 962/7% to 1 053/4%.

 

Discussion and conclusions

The number of EMS patients with subsequent hospital contact almost doubled during the years and number of older patients increased with a factor 2.5. The non-specific diagnoses dominated the pattern with around 40%, while cardiovascular diagnoses constituted only 10-12%. Although time-critical conditions are of great importance in EMS, an entirely different group of patients – the non-specific diagnoses, dominates the population. In addition, more awareness should be directed towards the increasing number of patients with increasing age. In future research, we plan to investigate to which extent demographic changes can explain the increasing age of the EMS population.

OP060 Bedside ultrasound in acute patients with suspected kidney involvement - a prospective observational study.

Background
Complicated urinary tract infections leading to treatment failure and readmissions is a common challenge in the emergency department (ED). An identified risk factor is obstructive uropathy. The diagnosis of hydronephrosis based on the initial clinical assessment and blood test in the emergency department is challenging.
Point-of-care ultrasound (POCUS) has the advantage of being non-radiating, rapid to apply and with increasing accessibility. POCUS has shown to be valuable when assessing the abdomen of trauma patients.
The aim of this study is to investigate incidence of hydronephrosis in patients presenting with symptoms of urinary tract infection or dehydration using POCUS in the ED and evaluate its clinical relevance and accuracy.

Methods
In this observational, prospective semi-blinded single-center study, patients were included based on preliminary diagnosis reported from general practitioner or from triage in the ED. Inclusion criteria were dehydration defined by laboratory values or urinary tract infections. In addition, patients had to present at least one of the following symptoms: Dysuria, flank pain, elevated creatinine or renal colic. Patients were collected as a convenience sample Patients were included if aged above 18 and able to perform written consent.
POCUS of the bladder and kidneys was performed within 4 hours after admission. Results from the POCUS was blinded to the treating physician (TP) until the first questionnaire concerning radiological prescriptions was completed. After revealing the POCUS results the TP evaluated the primary assessment through a second questionnaire.
Primary outcome was hydronephrosis and urinary retention. Secondary outcome was an evaluation of applicability. Relevance and applicability were answered by analysis of questionnaires and patient laboratory values using sensitivity and specificity, chi2-test and logistic regression. 

Results
153 patients were included during day and evening shift in the period November 4th 2018 to April 5th 2019. Hydronephrosis was found in at least one side in 10.5% (95% CI [0.98;0.22]) and urinary retention in 15.0% (95% CI [0.10;0.22]). 22.9% (95% CI [0.16;0.30]) presenting with either hydronephrosis or urinary retention. Hydronephrosis was not related to urinary retention in the study population (p=0.2384). 63 out of 150 TPs report by questionnaire POCUS to influence the clinical decision. TP prescribed further radiological examination in 9 of the 16 cases POCUS identified as having hydronephrosis (p=0.4340).

Discussion
Among limitations to this study is the single-center design and only two POCUS operators. Due to the sample size, correlations to predict subpopulations at risk for hydronephrosis remains weak. The non-coherence to urinary retention and TP assessment indicates the need for screening tools.
The use of questionnaires as measure of clinical consequence, lack specific values and actions, making it hard to analyze in terms of patient care and treatment.

Conclusion
This study found hydronephrosis in 1 in 10 included patients. Hydronephrosis based on clinical findings alone was rarely predicted, which supports POCUS as a valuable screening tool.

17:20 - 17:30 #18301 - OP005 Implementation of ketamine-propofol (“ketofol”) in a 1 on 4 ratio for adult procedural sedation at a university hospital emergency department – case series report on safety and effectivity.
Implementation of ketamine-propofol (“ketofol”) in a 1 on 4 ratio for adult procedural sedation at a university hospital emergency department – case series report on safety and effectivity.

Background:

Procedural sedation is a frequently performed procedure at the emergency ward and emergency physicians should be capable of performing this safely, effectively and independently. For clinical guidance we composed an easy and unambiguous protocol for procedural sedation applicable for nearly all patients and procedures. Our sedative of choice is a mixture of ketamine and propofol (“ketofol”) in a 1 on 4 ratio. Both ketamine and propofol are known to neutralise each other’s undesirable effects and ketamine adds an analgesic quality. Ketofol has proven effective and safe in studies and is non-inferior to propofol. Though it is most often used in a 1 on 1 ratio, both pharmacological and clinical studies favour a 1 on 4 ratio. We hypothesize our protocol with ketofol 1 on 4 is safe and effective and will serve to facilitate procedural sedation by emergency physicians.

Methods:

All adults presenting at the emergency ward of the University Hospital of Ghent between February 2018 and April 2019 and in need of procedural sedation would be included in a prospective case series study. Informed consent was obtained for both the sedation and the study. Patients with an American Society of Anesthesiologist physical status classification system score (ASA-score) of III or more, with an anticipated difficult airway or intoxicated patients were discussed with the anaesthesiology department to decide the feasibility of sedation in the emergency ward setting. Pregnant patients were excluded. Ketofol 1 on 4 was prepared by mixing 1ml of ketamine (50mg) and 20ml of propofol (200mg) in a single syringe and administrated as a loading dose of 1ml/10kg, followed by a stepwise titration in aliquots of 0,5ml/10kg. Above 65 years the loading dose was halved. Registered patient outcomes were respiratory and hemodynamic events, vomiting, agitation or hallucinations, and amnesia. In addition we measured satisfaction of the physician with the performed sedation.

Results:

Sixty-one patients, between 18 and 89 years old, with an ASA-score ranging from I to III were included. Six respiratory events were registered in as many patients (9,8 %), none of them serious. All involved airway obstruction, alleviated by head tilt and chin lift and with no repercussion on vital signs save one brief episode of desaturation. There were no hemodynamic events. No vomiting was reported. Five patients (8,2%) experienced pleasant hallucinations or dreams and one patient (1,6%) was agitated upon awakening but calmed rapidly without additional medication. Amnesia was present in 58 patients (95,1%). Physician satisfaction rate was 93,4%.

Discussion & conclusions:

Implementation of our protocol ensured amnesia in majority of patients, with a low frequency of complications. Only minor respiratory events and agitation or hallucinations were observed. Respiratory events were reported slightly less than in studies using propofol or ketofol in different proportions. The rate of agitation or hallucinations is similar to that of propofol monotherapy, but lower than studies using ketofol 1 on 1. Our protocol, using ketofol in a 1 on 4 ratio, appears safe and effective and resulted in a high physician satisfaction rate.

17:30 - 17:40 #19098 - OP114 Trends and Characteristics of Buprenorphine Sublingual Tablet Toxicities.
OP114 Trends and Characteristics of Buprenorphine Sublingual Tablet Toxicities.

Background: The number of patients with an opioid use disorder in the U.S. was estimated to be 2.6 million in 2015. Buprenorphine can be easily dispensed through office-based prescribers and community pharmacies, with 58% opioid treatment programs now offering buprenorphine. Buprenorphine sublingual tablets were discontinued in 2012 due to concerns about the misuse, abuse, and diversion. They were replaced with single dose sublingual films that are considered child-resistant and abuse deterrent. The objective of this study is to evaluate the trends, and characteristics of exposures to buprenorphine tablet formulations.

Methods: We retrospectively queried the National Poison Data System (NPDS) for all confirmed exposures to buprenorphine tablets from 1/1/2011 to 12/31/2016 as specified by the American Association of Poison Control Center Code (AAPCC) generic code and product name. We assessed the relevant characteristics of exposures descriptively. Frequencies and rates of buprenorphine tablet exposures (per 100,000 human exposures) were evaluated using Poisson regression methods, with the percent changes and corresponding 95% Confidence Intervals (95% CI) reported. Predictors of severe outcomes (major effects and death) to tablet exposures were also assessed with adjusted odds ratios (AOR) presented.

Results: Overall, there were 7,406 reports of exposures to buprenorphine sublingual tablets to the PCs during the study period. The reports of buprenorphine tablet exposures decreased from 1,780 to 468 during the study period, a decrease of 73.7% (95% CI: 64.1%, 78.7%; p<0.001), with exposures resulting in severe clinical outcomes decreasing from 49 in 2011 to 27 in 2016. The rate of exposures decreased by 71.3% during the study period. Children under 6 years of age represented 32.1% of the sample, while adults between 20 and 29 years of age accounted for 23.8% of the cases. The most common reason for exposure was unintentional (34.6 %), with intentional abuse (20.3%) being common (15.1%). Single substance exposures accounted for 63.9% of the cases and ingestion was the most common route of exposure. The case fatality rate for such exposures was 0.2%, with 3.9% cases demonstrating major effects. The proportion of major effects was highest among suspected suicides (9.5%) and abuse (4.5%) in comparison to cases of other exposure reasons such as unintentional. The Midwest region (37.4%) demonstrated the highest proportion of buprenorphine tablet exposures. An additional opioid was reported for 11.1% cases and naloxone was a commonly reported therapy for cases. Significant predictors of severe buprenorphine film exposures included suspected suicides (Ref: Unintentional reasons) (AOR: 1.96, 95% CI: 1.34 – 2.86), 3 or more co-occurring substances (AOR: 4.14, 95% CI: 1.87 – 9.14), and non-oral routes of exposure (AOR: 2.16, 95% CI: 1.31 – 3.56).   

Conclusions: Analysis of national data from the NPDS exhibited a significantly decreasing trend in the exposures to buprenorphine tablet products, with such exposures being frequent among children under 5 years of age. Considering the discontinuation of the sublingual tablets, it is imperative to explore in greater detail, the reasons for the observed exposures. Possible reasons for these observed exposures might be the continued availability despite discontinuation or potential diversion of the product

16:10 - 16:20 #18967 - OP055 “Mind your Head” – a quality improvement project assessing the advice given to patients following a head injury in a London Emergency Department.
OP055 “Mind your Head” – a quality improvement project assessing the advice given to patients following a head injury in a London Emergency Department.

Introduction 

Head injuries and concussion have been highlighted for years in the media due to athletes sustaining either fatal or life changing consequences. Therefore, managing patients with head injuries is an essential skill of all Emergency Physicians. An extensive literature analysis identified several areas for improvement, one of which was the head injury advice given to those who had sustained an injury needs to be consistent and adequate in its explanation for patients regarding further care. A quality improvement project was undertaken at a District General Hospital Emergency Department (ED) in London, to improve the safety and long-term care of patients who have sustained a head injury (HI), by ensuring they have up-to-date written advice regarding concussion and partaking in sports and exercise after their injury.  

Methods

There was concurrent analysis of the number of patients attending the ED with minor head injuries and review of the documentation by ED staff regarding the written HI and return to play (RTP) advice, over a six-month period. Three plan-do-study-act (PDSA) cycles were undertaken: doctors giving head injury and RTP advice, prompting patients to ask for advice and lastly empowering the triage nurses to give HI/RTP advice on first contact with the patient. The team analysed the numbers of documented written HI advice after each cycle and made modifications.

Results

National Institute for Health and Care Excellence (NICE) guidelines expect 100% of all patients to have written HI advice, therefore our aim was to have all patients given written HI advice, and 70% receiving RTP advice after an injury. Our results showed that with improving awareness, teaching and access to HI and RTP advice, the number of patients receiving written HI advice improved. Over 71% of patients received written head injury advice after the 2nd PDSA cycle, and our rate of written RTP increased to 13%, from a baseline of zero. The third cycle showed a decrease in patients receiving written HI (60%) and RTP (6%) advice.

Conclusions

The results demonstrate the positive outcome of regular teaching and awareness for staff as well as patients in a busy Emergency Department. Appropriately documented discharge advice to patients on head injuries, concussion and their day-to-day activities is good medical practice. Adequate explanation of concussive symptoms to patients with head injuries and advising them correctly about further exercise and activity is good medical practice, as well as documenting the advice given. Improving staff knowledge in early recognition and long-term management of head injuries increased staff confidence in supplying RTP/HI advice. Our next steps are to establish a head injury/concussion clinic within our ED, with due consideration of making an “App” designed for patient use during and after their attendance in the ED.

16:20 - 16:30 #18441 - OP056 Serum Cholesterol Level as Prognostic Factor in Post-cardiac Arrest Patients.
OP056 Serum Cholesterol Level as Prognostic Factor in Post-cardiac Arrest Patients.

Background: Low cholesterol level has been investigated as the risk factor of onset of sepsis and prognostic factor of mortality. Sepsis is complicated inflammatory process with ischemic-reperfusion injuries. Post-cardiac arrest syndrome also has global ischemic-reperfusion injury and considered as sepsis-like syndrome due to the severe inflammatory process. In previous study, oxidative stress was elevated and cholesterol levels were lower in post-cardiac arrest patients compared to normal patients. The aim of this study was to investigate whether initial serum cholesterol levels can predict the survival discharge and neurologic outcome in post-cardiac arrest patients.

Methods: This was a retrospective observational study performed in a tertiary care teaching hospital in South Korea from January 2012 to June 2018. Patients visiting emergency room (ER) with cardiac arrest or with recovery from cardiac arrest were screened. Patients followed by return of spontaneous circulation (ROSC) and admission for post cardiac arrest care were included. Patients who is younger than 18 years old and who did not take serum cholesterol level test were excluded. Patients were managed as Korean guideline of advanced cardiopulmonary life support (ACLS), 2015. After ROSC, all the patients were received post cardiac arrest care including targeted temperature management (TTM). Demographics, underlying disease, variables related to cardiac arrest, laboratory findings, radiologic data, received management, severity score as sequential organ failure assessment (SOFA) and variables related to outcome were collected. Cerebral performance category (CPC) was used as scoring system of neurological outcome. CPC 1 or 2 were defined as good neurological outcome and CPC 3 to 5 were defined as bad neurological outcome. The significance of intergroup differences was assessed by Fisher’s exact test or Mann-Whitney U test. Multiple logistical regression analysis was performed to identify the factors that could be considered independent factor for the prognosis. The performance to predict prognosis was checked using the area under the receiver operating characteristic curves (AUROC).

Results: 355 patients were enrolled. 192 patients (54.1%) were survived at discharge. 76 patients (21.4%) at discharge and 64 patients (18.0%) at 1 month after discharge had good CPC. Cholesterol levels at admission were significantly high in patients with survival (p=0.01), good CPC at discharge (p=0.00) and good CPC at 1 month after discharge (p=0.00). Multivariate logistic regression revealed that duration of CPR and cardiac cause, SOFA score were the predicting factor of survival (p=0.00). Predicting factors of good CPC at discharge were duration of CPR and cardiac cause, cholesterol level(p=0.000). Predicting factors of good CPC at 1 month after discharge were duration of CPR and cardiac cause, SOFA score, cholesterol level (p=0.000). AUROC of the cholesterol to predict survival, good CPC at discharge and 1 month after discharge were 0.603, 0.696 and 0.710, respectively.

Conclusions: Serum cholesterol level at admission was higher in survived patients and patients with good neurologic outcome. Duration of CPR, cause of arrest and SOFA score were predicting factor of survival and good neurological outcome. Serum cholesterol level at admission was one of the predicting factors for good neurological outcome in post cardiac-arrest patient.

16:30 - 16:40 #18605 - OP057 The effects of thoracic cage dimension and chest subcutaneous adipose tissue on outcomes of adults with in-hospital cardiac arrest: A retrospective cohort study.
OP057 The effects of thoracic cage dimension and chest subcutaneous adipose tissue on outcomes of adults with in-hospital cardiac arrest: A retrospective cohort study.

Background: Increasing evidence has revealed that an adequate but uniform compression depth may not be suitable for all adults with various body sizes. The thoracic anteroposterior (AP) diameter is a commonly used parameter to reflect the thoracic cage dimension. Delivery of an adjustable compression depth based on thoracic AP diameter is recommended in pediatric resuscitation guidelines, but whether the thoracic cage dimension has impact on the prognosis for adult patients with cardiac arrest remains under debate. revealed the association between increasing SAT depth and compression inadequacy. But to date, whether the SAT-caused compression inadequacy leads to adverse outcomes of patients with cardiac arrest was unknown. This study aimed to investigate the associations between thoracic cage dimension, chest subcutaneous adipose tissue (SAT) depth and outcomes of adults with in-hospital cardiac arrest (IHCA).

Methods: We retrospectively evaluated patients with IHCA between January 2016 and October 2017. The thoracic cage transverse diameter, internal AP diameter, cross-sectional area, anterior and posterior SAT depths were measured in computed-tomography (CT) images using the three-dimensional visualization software (Mimics Interactive Medical Image Control System, Version 17.0, Materialize Company, Belgium). Using logistic regression models, we determined the adjusted associations between thoracic cage dimension, SAT depths and the prognosis for IHCA. The primary outcome was sustained return of spontaneous circulation (ROSC) and the secondary outcome was survival to hospital discharge.

Results: Among 423 IHCA patients, 258 patients achieved ROSC and 70 survived to discharge. Smaller cross-sectional area and posterior SAT depth were significantly related to ROSC. Smaller posterior SAT depth was associated with ROSC. After multivariate adjustment, the smaller cross-sectional area was independently associated with ROSC (Odds ratio [OR] 0.99, 95% confidence interval [95%CI] 0.99-1.00; p = 0.008) and survival to discharge (OR 0.99, 95%CI 0.98-1.00; p = 0.024), and the smaller posterior SAT depth was independently related to ROSC (OR 0.65, 95%CI 0.44-0.96; p = 0.030), whereas no relation to survival to discharge was found.

Conclusions: In adults with IHCA, the smaller thoracic cage dimension and posterior SAT depth are associated with better survival. An adjustable compression depth based on the thoracic cage dimension might be better than the “one-size-fits-all” compression depth for resuscitating CA patients. In addition, physicians should pay extra attention to compression efficacy when resuscitating obese patients.

16:40 - 16:50 #18642 - OP058 Cut-off values of serum potassium and core temperature at hospital admission for extracorporeal rewarming of avalanche victims in cardiac arrest: a retrospective multi-centre study.
OP058 Cut-off values of serum potassium and core temperature at hospital admission for extracorporeal rewarming of avalanche victims in cardiac arrest: a retrospective multi-centre study.

Aim: About 165 avalanche deaths are recorded per year in Europe and in North-America. Survival analyses suggest that most completely buried avalanche victims die by asphyxiation between 15 and 35 minutes after burial. Unlike asphyxia, hypothermia develops after long burial if the completely buried avalanche victim is able to breathe. These avalanche victims may recover without neurological sequelae. Recommendations for the pre-hospital triage of avalanche victims were based on expert consensus and case series with, admittedly, low levels of evidence and have not previously been validated using a large dataset. This study attempted to find reliable cut-off values for the identification of hypothermic avalanche victims with reversible out-of-hospital cardiac arrest (OHCA) at hospital admission. This may enable hospitals to allocate extracorporeal life support (ECLS) resources more appropriately while increasing the proportion of survivors among rewarmed victims.

Methods: This was a retrospective multi-centre study. Seven European hospitals that are capable of ECLS and have admitted avalanche victims with OHCA participated in the study: Bern (Switzerland), Grenoble (France), Innsbruck (Austria), Krakow (Poland), Tromsø (Norway), Lausanne and Sion (Switzerland). Approval by local institutional review boards was provided by the participating hospitals. All admitted avalanche victims with OHCA from 1995 to 2016 were included. To identify parameters that contribute independently to survival we performed a stepwise logistic regression on survival with respect to sex, age, duration of burial, core temperature, serum potassium and pH. Optimal cut-off values, for the parameters identified by logistic regression, were determined by means of bootstrapping and exact binomial distribution and served to calculate sensitivity, rate of overtriage, positive and negative predictive values, and receiver operating curve (ROC) analysis.

Results: In total, 103 avalanche victims with OHCA were included. Of the 103 patients 61 (58%) were rewarmed by ECLS. Six (10%) of the rewarmed patients survived whilst 55 (90%) died. The observed maximum value for core temperature in survivors was 27.8 °C. For serum potassium the observed maximum value in survivors was 4.8 mmol/L. In multivariate analysis logistic regression the parameters core temperature (p=0.02) and serum potassium (p=0.03) were statistically, significantly related to survival. Using cut-offs of 7 mmol/L and 30°C resulted in an overtriage rate of 47% (95% CI 35%-60%), negative predictive value of 100% (95% CI 92%-100%) and positive predictive value of 19% (95% CI 8%-35%). We obtained optimal cut-off values of 7 mmol/L for serum potassium and 30°C for core temperature.

Conclusion: For in-hospital triage of avalanche victims admitted with OHCA, serum potassium accurately predicts survival. The combination of the cut-offs 7 mmol/L for serum potassium and 30°C for core temperature achieved the lowest overtriage rate and the highest positive predictive value, with a sensitivity of 100% for survivors. The presence of vital signs at extrication is strongly associated with survival. For further optimisation of in-hospital triage, larger datasets are needed to include additional parameters.

OP059 The development of a resuscitation record at an academic hospital: a survey and focus group of Code Blue team members.

Background: A Code Blue is activated when a hospitalized patient suffers a cardiac arrest. Accurate documentation of the resuscitation effort is required in order to provide reliable data that will facilitate decision-making, code team debriefing, and inform quality improvement initiatives related to Code Blues. The documentation of Code Blues is not well defined by current guidelines and varies considerably between institutions. Using a survey and focus group, we aimed to improve our Code Blue documentation record in order to increase its completion rate and capture evidence-based quality metrics.

Methods: This study was reviewed and approved by the Queen’s University Health Sciences & Affiliated Teaching Hospitals Research Ethics Board and conducted from January to May, 2019. We distributed a 16-question survey containing a mixture of short answer, multiple choice, ranked, and narrative feedback questions to volunteer Code Blue personnel, including staff from nursing, respiratory therapy, anesthesiology, and emergency medicine. The survey aimed to assess their perceptions of the current resuscitation record by evaluating: 1) the individual priorities of members of the resuscitation team as they pertain to information recording; 2) features of the documentation that facilitate or hinder accurate information recording; and 3) types of information necessary for making treatment decisions and debriefing after the event. We then conducted a focus group with the Code Blue team to foster an interprofessional dialogue about the purpose of the resuscitation record and to create a framework that would guide the record’s redesign. With the aggregate feedback, we created three new resuscitation record templates that reflected the team’s content and formatting suggestions.

Results: The survey identified key information that the Code Blue team would need for decision-making and debriefing. In addition, several features of the current resuscitation record were minimally or improperly used and slowed recording of the event. These included outdated medication fields and terminology, formatting that limited complete information recording, and a lack of prompts for key information. The focus group re-iterated this feedback and proposed suggestions that were separated into content redesign, which reflects the completeness and relevance of recorded information, and formatting redesign, which reflects the ease and accuracy of recording information. The three new templates contained increasing degrees of content and formatting redesign compared to the original resuscitation record. Our next steps are to select one template through consensus that best closes the gaps in information recording identified by the Code Blue team.

Discussion & Conclusion: Accurate documentation during a Code Blue is critical in order to provide high-quality data that will drive the improvement of decision-making, debriefing, and ultimately patient outcomes. This study aimed to highlight shortcomings in the current documentation and strategies to improve the relevance and accuracy of information recorded during a resuscitation. We used a survey and focus group to perform a needs assessment of Code Blue team members and guide the redesign process in an evidence-based manner.

17:10 - 17:20 #18469 - OP061 Novel wearable cooling device for early initiation of targeted temperature management in the emergency department: a retrospective cohort study.
OP061 Novel wearable cooling device for early initiation of targeted temperature management in the emergency department: a retrospective cohort study.

Aim: Targeted temperature management (TTM) is an important component of post-cardiac arrest care. Although the optimum cooling method is not known, studies have suggested that prompt and quick cooling is associated with better outcomes. The aim of this study was to evaluate the cooling efficacy of a protocol including a novel cooling device in the Emergency Department (ED).

Methods: This was a single-center pre-post cohort study of post-cardiac arrest patients with return of spontaneous circulation (ROSC), for whom TTM was initiated at a tertiary hospital between April 2010 and December 2017. A surface cooling device (CarbonCool, Global Healthcare Pte Ltd), which uses a graphite cooling material in an insulating suit, was introduced in July 2015. Control patients enrolled before the intervention period received icepacks in the ED and cold saline. For both periods, the target temperature was 34.0oC, with TTM continued in the ICUs. The primary outcome was time from ROSC to target temperature (TT).

Results: Of 124 patients included, 40 were in the intervention period and 84 in the control period. Time from ROSC to TT was significantly lower in the intervention period at 119 (Interquartile range (IQR): 65-250) minutes versus 482 (IQR: 356-596) minutes (p<0.001). There was no statistical difference in survival to discharge (30.0% versus 32.1%, p=0.839) and Glasgow-Pittsburg Outcome scores (1 or 2 in 17.5% versus 21.4%, p=0.811). The intervention period also had a faster cooling rate (initiation of TTM to TT of 73 (IQR: 40-150) versus 142 (IQR: 75-262) minutes, p=0.014). There were no reported serious adverse events associated with the device.

Conclusion: Use of a novel cooling device in the ED resulted in a shorter time to target temperature. As it is reusable and does not require a power source, it has potential to be an affordable solution for pre-hospital and transport cooling.

17:20 - 17:30 #18535 - OP062 Thirty-day mortality in atrial fibrillation patients with gastrointestinal bleeding in the emergency department: differences between direct oral anticoagulant and warfarin users.
OP062 Thirty-day mortality in atrial fibrillation patients with gastrointestinal bleeding in the emergency department: differences between direct oral anticoagulant and warfarin users.

Background:

The ageing of the population, the better knowledge of the cardio-embolic risk and the availability of new oral anticoagulant drugs that do not require continuous laboratory monitoring, have allowed an exponential spread of oral anticoagulant therapy. More clinical data are required on the safety of direct oral anticoagulants (DOACs). Although patients treated with warfarin and DOACs have a similar risk of bleeding, short-term mortality after a gastrointestinal bleeding (GIB) episode in DOAC-treated patients has not been clarified.

Objectives: To assess differences in 30-day mortality in patients treated with DOACs or warfarin admitted to the emergency department (ED) for GIB.

Methods: This was a multicentre retrospective study conducted over two years. The study included patients evaluated at three different EDs for GIB during oral anticoagulant therapy. The baseline characteristics were included. The two treatment groups (DOACs vs warfarin) were compared to evaluate any possible imbalance in the anamnestic or clinical characteristics. Here, the use of propensity score matching had to be considered to equilibrate the two groups and to obtain a homogeneous cohort of patients for prognostic evaluation. Comparison with the clinical and anamnestic variables was performed using the Mann–Whitney U test and with Fisher’s exact test, as appropriate. Cox regression, adjusted for all variables that were significant to the previous univariate analysis, was performed to verify differences in mortality between the two treatment groups. Finally, the Kaplan–Meier method was used to compare 30-day survival between DOAC and warfarin users. Results: Among the 284 patients presenting GIB enrolled in the study period, 39.4% (112/284) were treated with DOACs, and 60.6% (172/284) were treated with warfarin. Propensity score matching was not needed, as the two groups did not show significant differences in anamnestic or clinical characteristics except for the concomitant platelet therapy (11.6% vs 2.7%, p = 0.007). Overall, 8.1% (23/284) of patients died within 30 days. The factors associated with 30-day mortality risk were age, history of chronic renal disease, active cancer, HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly) value, and bleeding type (major GIB) and site (upper GIB). After the univariate analysis, neither of the two anticoagulant treatments resulted in higher 30-day mortality risk (warfarin 8.7% vs DOACs 7.1%, p = 0.824). Cox analysis adjusted for age, chronic renal disease, major GIB, upper GIB, and baseline HAS-BLED, showed no difference in mortality within 30 days of the GIB episode between the two groups (p=0.533). The Kaplan–Meier curves showed no difference in 30-day survival between the warfarin and DOAC users (p = 0.651).

Conclusions: Despite their rapid diffusion, the available evidence ON DOACs is lacking, and the GIB prognosis of anticoagulated patients remains unclear. The present study shows no differences between DOACs and warfarin in short-term mortality after GIB.

17:30 - 17:40 #18586 - OP063 Survey to detect unmet palliative care needs in the emergency department: First results of a questionnaire-based two-level screening process.
OP063 Survey to detect unmet palliative care needs in the emergency department: First results of a questionnaire-based two-level screening process.

Background and Objectives: The use of a screening tool to identify palliative care needs leads to a reduction of unwanted and highly invasive interventions in emergency patients with terminal illnesses.

Many of these patients enter clinical care through prehospital emergency medical services (EMS) and the emergency department (ED). Screening for palliative care needs at this interface can reduce loss of information and strengthen the patient’s autonomy in further clinical treatment.

 

Methods: We developed a two-level questionnaire summarizing existent criteria which indicate palliative care needs. Terminal illness and/or progressive malignant disease and a negative answer to the “Surprise-Question - Would you be surprised if the patient dies within the next 12 months due to their condition?” function as inclusion criteria to the screening process.  

Level 1 asks for the patient´s wishes, advanced directives, load of symptoms, psychosocial background and resources, as well as assignment from a nursing home. These questions are meant to be answered by the preclinical emergency medical team.

Level 2 is directed to the emergency physician at the ED. It is meant to confirm the surprise question and gives further detail about the terminal illness of the patient. Furthermore, it assesses if the patient has already been admitted to the hospital within the last 3 months.

As the investigation progresses, our defined goal is to determine the sensitivity and specificity, as well as the predictive values of our screening questionnaire. Therefore, we compare the assessment to a specialised palliative care physician´s consultation as gold-standard to evaluate palliative care needs. For the statistical analysis, we will use the binary logistic regression model.

 

Results: The eligibility criteria were met in 15 cases in which the availability of a palliative care consultation was given, too. 73% (11/15) of the patients who underwent the screening process were assigned through EMS, the remaining quarter was detected in the triage process at the ED.

Screening level 2 confirmed in 93.3% (14/15) the underlying terminal disease and in every case (15/15) a “No” to the “Surprise-Question”. 40% (6/15) of the trial participants passed away before the consult took place. Palliative care needs were confirmed in 8 out of 9 consultations (88.8%). 46.6% (7/15) of the study population died within the ED under palliative treatment, four further participants died during the hospital stay – overall 80%.

 

Discussion: We present data deriving from the first two months of experience after initiating the survey to show the feasibility of the two-level questionnaire concept.

The implemented screening process was suitable to adopt the strategy of care in the emergency department. In several cases palliative care and support of the patients and their families can be performed.
