The syncope core management process in the emergency department: a consensus statement of the EUSEM syncope group.

The European Society of Cardiology issued updated syncope guidelines in 2018 which included recommendations for managing syncope in the emergency department (ED) setting. However, these guidelines lack detailed process-oriented instructions regarding the fact that ED syncope patients initially present with a transient loss of consciousness (TLOC), which can have a broad spectrum of causes. This study aims to establish a European consensus on the general process of the workup and care for patients with suspected syncope and provides rules for sufficient and systematic management of the broad group of syncope (initially presenting as TLOC) patients in the ED. A variety of European diagnostic and therapeutic standards for syncope patients were reviewed and summarized in three rounds of a modified Delphi process by the European Society for Emergency Medicine syncope group. Based on a consensus statement, a detailed process pathway is created. The primary outcome of this work is the presentation of a universal process pathway for the structured management of syncope patients in European EDs. The here presented extended event process chain (eEPC) summarizes and homogenizes the process management of European ED syncope patients. Additionally, an exemplary translation of the eEPC into a practice-based flowchart algorithm, which can be used as an example for practical use in the ED, is provided in this work. Syncope patients, initially presenting with TLOC, are common and pose challenges in the ED. Despite variations in process management across Europe, the development of a universally applicable syncope eEPC in the ED was successfully achieved. Key features of the consensus and eEPC include ruling out life-threatening causes, distinguishing syncope from nonsyncopal TLOCs, employing syncope risk stratification categories and based on this, making informed decisions regarding admission or discharge.

Predictive performance of the common red flags in emergency department headache patients: a HEAD and HEAD-Colombia study.

OBJECTIVES: Only a small proportion of patients presenting to an ED with headache have a serious cause. The SNNOOP10 criteria, which incorporates red and orange flags for serious causes, has been proposed but not well studied. This project aims to compare the proportion of patients with 10 commonly accepted red flag criteria (singly and in combination) between patients with and without a diagnosis of serious secondary headache in a large, multinational cohort of ED patients presenting with headache. METHODS: Secondary analysis of data obtained in the HEAD and HEAD-Colombia studies. The outcome of interest was serious secondary headache. The predictive performance of 10 red flag criteria from the SNNOOP10 criteria list was estimated individually and in combination. RESULTS: 5293 patients were included, of whom 6.1% (95% CI 5.5% to 6.8%) had a defined serious cause identified. New neurological deficit, history of neoplasm, older age (>50 years) and recent head trauma (2-7 days prior) were independent predictors of a serious secondary headache diagnosis. After adjusting for other predictors, sudden onset, onset during exertion, pregnancy and immune suppression were not associated with a serious headache diagnosis. The combined sensitivity of the red flag criteria overall was 96.5% (95% CI 93.2% to 98.3%) but specificity was low, 5.1% (95% CI 4.3% to 6.0%). Positive predictive value was 9.3% (95% CI 8.2% to 10.5%) with negative predictive value of 93.5% (95% CI 87.6% to 96.8%). CONCLUSION: The sensitivity and specificity of the red flag criteria in this study were lower than previously reported. Regarding clinical practice, this suggests that red flag criteria may be useful to identify patients at higher risk of a serious secondary headache cause, but their low specificity could result in increased rates of CT scanning.

Acute Serum Calcium Level Changes Following Non-Massive Blood and Blood Product Transfusion in Emergency Department; a Cross-sectional Study.

Introduction: The specific impact on calcium dynamics after non-massive blood transfusions remains relatively unexplored. This study aimed to compare pre- and post-transfusion calcium levels in patients receiving blood and blood product in the emergency department. Methods: This is a single-center, prospective, cross-sectional study conducted at the Emergency Department of Gazi University Health Research and Application Center Hospital in Ankara, Turkey, from January 1, 2020, to August 31, 2020. The study included adult patients who underwent blood and blood product transfusions, and serum calcium levels were measured and compared from samples taken before and after transfusion. Results: A total of 292 participants were enrolled in the study, with 242 participants included in the final analysis. The mean total calcium level was 8.41 ± 0.76 mg/dL before transfusion and 8.34 ± 0.71 mg/dL after transfusion (p=0.012). When examining the corrected calcium values after receiving blood products based on the type of blood products, participants who received apheresis platelets had a post-transfusion corrected calcium value of 8.26 ±0.41 mg/dL, with a pre-transfusion value of 9.09 ±0.49 mg/dL (p<0.01). The post-transfusion ionized calcium value for participants receiving apheresis was 1.04 ±0.08 mg/dL, compared to 1.15 ±0.09 mg/dL for those who did not receive apheresis (p=0.049). There was a significant relationship between receiving fresh frozen plasma and post-transfusion ionized calcium values (p=0.024). Conclusion: This study demonstrated that transfusion-associated hypocalcemia can occur even at mild levels in patients receiving blood and blood product transfusions in the emergency department. However, it is suggested that the clinical effects of hypocalcemia, even when occurring based on the type and quantity of blood products, are minimal and negligible.

Management of syncope in the Emergency Department: a European prospective cohort study (SEED).

BACKGROUND AND IMPORTANCE: In 2018, the European Society of Cardiology (ESC) produced syncope guidelines that for the first-time incorporated Emergency Department (ED) management. However, very little is known about the characteristics and management of this patient group across Europe. OBJECTIVES: To examine the prevalence, clinical presentation, assessment, investigation (ECG and laboratory testing), management and ESC and Canadian Syncope Risk Score (CSRS) categories of adult European ED patients presenting with transient loss of consciousness (TLOC, undifferentiated or suspected syncope). DESIGN: Prospective, multicentre, observational cohort study. SETTINGS AND PARTICIPANTS: Adults (≥18 years) presenting to European EDs with TLOC, either undifferentiated or thought to be of syncopal origin. MAIN RESULTS: Between 00:01 Monday, September 12th to 23:59 Sunday 25 September 2022, 952 patients presenting to 41 EDs in 14 European countries were enrolled from 98 301 ED presentations (n = 40 sites). Mean age (SD) was 60.7 (21.7) years and 487 participants were male (51.2%). In total, 379 (39.8%) were admitted to hospital and 573 (60.2%) were discharged. 271 (28.5%) were admitted to an observation unit first with 143 (52.8%) of these being admitted from this. 717 (75.3%) participants were high-risk according to ESC guidelines (and not suitable for discharge from ED) and 235 (24.7%) were low risk. Admission rate increased with increasing ESC high-risk factors; 1 ESC high-risk factor; n = 259 (27.2%, admission rate=34.7%), 2; 189 (19.9%; 38.6%), 3; 106 (11.1%, 54.7%, 4; 62 (6.5%, 60.4%), 5; 48 (5.0%, 67.9%, 6+; 53 (5.6%, 67.9%). Furthermore, 660 (69.3%), 250 (26.3%), 34 (3.5%) and 8 (0.8%) participants had a low, medium, high, and very high CSRS respectively with respective admission rates of 31.4%, 56.0%, 76.5% and 75.0%. Admission rates (19.3-88.9%), use of an observation/decision unit (0-100%), and percentage high-risk (64.8-88.9%) varies widely between countries. CONCLUSION: This European prospective cohort study reported a 1% prevalence of syncope in the ED. 4 in 10 patients are admitted to hospital although there is wide variation between country in syncope management. Three-quarters of patients have ESC high-risk characteristics with admission percentage rising with increasing ESC high-risk factors.

Emergency Response and Clinical Insights from a Non-Epicenter Hospital during the 2023 Turkey-Syria Earthquake: A Retrospective Analysis.

BACKGROUND The Turkey-Syria earthquake of February 6, 2023, impacted 11 provinces and necessitated widespread emergency medical support. Although not at the disaster's epicenter, Ankara Mamak State Hospital in Ankara, Turkey, offered critical multidisciplinary support. This retrospective study evaluates the factors that drove 124 admissions to the hospital's Emergency Department (ED) following the earthquake. MATERIAL AND METHODS We recorded patient demographic data, dates of arrival at the ED, provinces of origin, diagnoses, treatments, consultations during the ED visit, and patient outcomes. The majority of the 124 admissions were due to trauma and multi-organ damage, and the primary diagnostic tools were physical examination and radiological imaging. Of these patients, 85.5% (106) recovered and were discharged directly from the ED, 11 were admitted for continued care, and 7 were referred to another hospital. RESULTS The 124 cases consisted of adults injured within the first 20 days post-earthquake, with a mean age of 46.5±17.4 years, and a higher number of females. A peak in admissions was observed on the third and fourth days following the earthquake, with the most cases originating from the Hatay province. The most frequently injured body region was the lower extremity, and orthopedic consultations significantly outnumbered other surgical consultations. CONCLUSIONS Our findings underscore the vital role of robust, multidisciplinary disaster preparedness in all EDs, especially in regions prone to natural disasters.

Computed tomography brain scan utilization in patients with headache presenting to emergency departments: a multinational study.

BACKGROUND AND IMPORTANCE: Recommended indications for emergency computed tomography (CT) brain scans are not only complex and evolving, but it is also unknown whether they are being followed in emergency departments (EDs). OBJECTIVE: To determine the CT utilization and diagnostic yield in the ED in patients with headaches across broad geographical regions. DESIGN: Secondary analysis of data from a multinational cross-sectional study of ED headache presentations over one month in 2019. SETTING AND PARTICIPANTS: Hospitals from 10 participating countries were divided into five geographical regions [Australia and New Zealand (ANZ); Colombia; Europe: Belgium, France, UK, and Romania; Hong Kong and Singapore (HKS); and Turkey). Adult patients with nontraumatic headache as the primary presenting complaint were included. Patients were identified from ED management systems. OUTCOME MEASURES AND ANALYSIS: The outcome measures were CT utilization and diagnostic yield. CT utilization was calculated using a multilevel binary logistic regression model to account for clustering of patients within hospitals and regions. Imaging data (CT requests and reports) were sourced from radiology management systems. MAIN RESULTS: The study included 5281 participants. Median (interquartile range) age was 40 (29-55) years, 66% were women. Overall mean CT utilization was 38.5% [95% confidence interval (CI), 30.4-47.4%]. Regional utilization was highest in Europe (46.0%) and lowest in Turkey (28.9%), with HKS (38.0%), ANZ (40.0%), and Colombia (40.8%) in between. Its distribution across hospitals was approximately symmetrical. There was greater variation in CT utilization between hospitals within a region than between regions (hospital variance 0.422, region variance 0.100). Overall mean CT diagnostic yield was 9.9% (95% CI, 8.7-11.3%). Its distribution across hospitals was positively skewed. Regional yield was lower in Europe (5.4%) than in other regions: Colombia (9.1%), HKS (9.7%), Turkey (10.6%), and ANZ (11.2%). There was a weak negative correlation between utilization and diagnostic yield ( r  = -0.248). CONCLUSION: In this international study, there was a high variation (28.9-46.6%) in CT utilization and diagnostic yield (5.4-11.2%) across broad geographic regions. Europe had the highest utilization and the lowest yield. The study findings provide a foundation to address variation in neuroimaging in ED headache presentations.

Epidemiology of geriatric patients presenting to emergency departments in Europe: EGERS study.

BACKGROUND AND IMPORTANCE: Patients aged 65 and above constitute a large and growing part of emergency department (ED) visits in western countries. OBJECTIVE: The primary aim of this European prospective study was to determine the epidemiologic characteristics of elderly patients presenting to EDs across Europe. Our secondary objective was to determine the hospitalization rate, characteristics, and in-hospital mortality rates of geriatric patients presenting to EDs. DESIGN SETTING AND PARTICIPANTS: An observational prospective cohort study over seven consecutive days between 19 October and 30 November 2020, in 36 EDs from nine European countries. Patients aged 65 years and older presenting to EDs with any complaint during a period of seven consecutive days were included. OUTCOME MEASURES: Data were collected on demographics, the major presenting complaint, the presenting vital signs, comorbidities, usual medication, and outcomes after the ED, including disposition, in-hospital outcome, and the final hospital diagnosis. The patients were stratified into three groups: old (65-74 years), older (75-84 years), and oldest age (>85 years). MAIN RESULTS: A total of 5767 patients were included in the study. The median age of the patients was 77 (interquartile range: 71-84) years. The majority presented with a non-traumatic complaint (81%) and about 90% of the patients had at least one comorbid disease and were on chronic medication. An ED visit resulted in subsequent hospital admission in 51% of cases, with 9% of patients admitted to an intensive care unit. Overall in-hospital mortality was 8%, and ED mortality was 1%. Older age was associated with a higher female proportion, comorbidities, need for home care service, history of previous falls, admission rates, length of ED, and hospital stay. CONCLUSION: The characteristics of ED elderly patients and their subsequent hospital stay are reported in this prospective study.

Thunderclap headache syndrome presenting to the emergency department: an international multicentre observational cohort study.

BACKGROUND: Most headache presentations to emergency departments (ED) have benign causes; however, approximately 10% will have serious pathology. International guidelines recommend that patients describing the onset of headache as 'thunderclap' undergo neuroimaging and further investigation. The association of this feature with serious headache cause is unclear. The objective of this study was to determine if patients presenting with thunderclap headache are significantly more likely to have serious underlying pathology than patients with more gradual onset and to determine compliance with guidelines for investigation. METHODS: This was a planned secondary analysis of an international, multicentre, observational study of adult ED patients presenting with a main complaint of headache. Data regarding demographics, investigation strategies and final ED diagnoses were collected. Thunderclap headache was defined as severe headache of immediate or almost immediate onset and peak intensity. Proportion of patients with serious pathology in thunderclap and non-thunderclap groups were compared by χ² test. RESULTS: 644 of 4536 patients presented with thunderclap headache (14.2%). CT brain imaging and lumbar puncture were performed in 62.7% and 10.6% of cases, respectively. Among patients with thunderclap headache, serious pathology was identified in 10.9% (95%CI 8.7% to 13.5%) of cases-significantly higher than the proportion found in patients with a different headache onset (6.6% (95% CI 5.9% to 7.4%), p<0.001.). The incidence of subarachnoid haemorrhage (SAH) was 3.6% (95% CI 2.4% to 5.3%) in those with thunderclap headache vs 0.3% (95% CI 0.2% to 0.5%) in those without (p<0.001). All cases of SAH were diagnosed on CT imaging. Non-serious intracranial pathology was diagnosed in 87.7% of patients with thunderclap headache. CONCLUSIONS: Thunderclap headache presenting to the ED appears be associated with higher risk for serious intracranial pathology, including SAH, although most patients with this type of headache had a benign cause. Neuroimaging rates did not align with international guidelines, suggesting potential need for further work on standardisation.

The emergency department arrival mode and its relations to ED management and 30-day mortality in acute heart failure: an ancillary analysis from the EURODEM study.

BACKGROUND: Acute heart failure patients are often encountered in emergency departments (ED) from 11% to 57% using emergency medical services (EMS). Our aim was to evaluate the association of EMS use with acute heart failure patients' ED management and short-term outcomes. METHODS: This was a sub-analysis of a European EURODEM study. Data on patients presenting with dyspnoea were collected prospectively from European EDs. Patients with ED diagnosis of acute heart failure were categorized into two groups: those using EMS and those self-presenting (non- EMS). The independent association between EMS use and 30-day mortality was evaluated with logistic regression. RESULTS: Of the 500 acute heart failure patients, with information about the arrival mode to the ED, 309 (61.8%) arrived by EMS. These patients were older (median age 80 vs. 75 years, p < 0.001), more often female (56.4% vs. 42.1%, p = 0.002) and had more dementia (18.7% vs. 7.2%, p < 0.001). On admission, EMS patients had more often confusion (14.2% vs. 2.1%, p < 0.001) and higher respiratory rate (24/min vs. 21/min, p = 0.014; respiratory rate > 30/min in 17.1% patients vs. 7.5%, p = 0.005). The only difference in ED management appeared in the use of ventilatory support: 78.3% of EMS patients vs. 67.5% of non- EMS patients received supplementary oxygen (p = 0.007), and non-invasive ventilation was administered to 12.5% of EMS patients vs. 4.2% non- EMS patients (p = 0.002). EMS patients were more often hospitalized (82.4% vs. 65.9%, p < 0.001), had higher in-hospital mortality (8.7% vs. 3.1%, p = 0.014) and 30-day mortality (14.3% vs. 4.9%, p < 0.001). The use of EMS was an independent predictor of 30-day mortality (OR = 2.54, 95% CI 1.11-5.81, p = 0.027). CONCLUSION: Most acute heart failure patients arrive at ED by EMS. These patients suffer from more severe respiratory distress and receive more often ventilatory support. EMS use is an independent predictor of 30-day mortality.

Migraine in the Emergency Department: A Prospective Multinational Study of Patient Characteristics, Management, and Outcomes.

BACKGROUND AND AIM: Migraine headache is commonly diagnosed in emergency departments (ED). There is relatively little real-world information about the epidemiology, investigation, management, adherence to therapeutic guidelines and disposition of patients treated in ED with a final diagnosis of migraine. The primary aim of the current study is to get a snapshot of assessment and management patterns of acute migraine presentations to the different settings of EDs with a view to raise awareness. METHODS: This is a planned sub-study of a prospective study conducted in 67 health services in 10 countries including Australia, New Zealand, Southeast Asia, Europe, and the UK investigating the epidemiology and outcome of adult patients presenting to ED with nontraumatic headache. Outcomes of interest for this study are demographics, clinical features (including severity), patterns of investigation, treatment, disposition, and outcome of patients diagnosed as having migraine as their final ED diagnosis. RESULTS: The cohort comprises 1,101 patients with a mean age of 39 years (SD ± 13.5; 73.7% [811]) were female. Most patients had had migraine diagnosed previously (77.7%). Neuroimaging was performed in 25.9% with a very low diagnostic yield or significant findings (0.07%). Treatment of mild migraine was in accordance with current guidelines, but few patients with moderate or severe symptoms received recommended treatment. Paracetamol (46.3%) and nonsteroidal anti-inflammatory drugs (42.7%) were the most commonly prescribed agents. Metoclopramide (22.8%), ondansetron (19.2%), chlorpromazine (12.8%), and prochlorperazine (12.8%) were also used. CONCLUSIONS: This study suggests that therapeutic practices are not congruent with current guidelines, especially for patients with severe symptoms. Efforts to improve and sustain compliance with existing management best practices are required.

Clinical presentation and assessment of older patients presenting with headache to emergency departments: A multicentre observational study.

OBJECTIVE: To describe the characteristics, assessment and management of older emergency department (ED) patients with non-traumatic headache. METHODS: Planned sub-study of a prospective, multicentre, international, observational study, which included adult patients presenting to ED with non-traumatic headache. Patients aged ≥75 years were compared to those aged <75 years. Outcomes of interest were epidemiology, investigations, serious headache diagnosis and outcome. RESULTS: A total of 298 patients (7%) in the parent study were aged ≥75 years. Older patients were less likely to report severe headache pain or subjective fever (both P < 0.001). On examination, older patients were more likely to be confused, have lower Glasgow Coma Scores and to have new neurological deficits (all P < 0.001). Serious secondary headache disorder (composite of headache due to subarachnoid haemorrhage (SAH), intracranial haemorrhage, meningitis, encephalitis, cerebral abscess, neoplasm, hydrocephalus, vascular dissection, stroke, hypertensive crisis, temporal arteritis, idiopathic intracranial hypertension or ventriculoperitoneal shunt complications) was diagnosed in 18% of older patients compared to 6% of younger patients (P < 0.001). Computed tomography brain imaging was performed in 66% of patients ≥75 years compared to 35% of younger patients (P < 0.001). Older patients were less likely to be discharged (43% vs 63%, P < 0.001). CONCLUSIONS: Older patients with headache had different clinical features to the younger cohort and were more likely to have a serious secondary cause of headache than younger adults. There should be a low threshold for investigation in older patients attending ED with non-traumatic headache.

Epidemiology, investigation, management, and outcome of headache in emergency departments (HEAD study)-A multinational observational study.

OBJECTIVE: To describe the epidemiology of nontraumatic headache in adults presenting to emergency departments (EDs). BACKGROUND: Headache is a common reason for presentation to EDs. Little is known about the epidemiology, investigation, and treatment of nontraumatic headache in patients attending EDs internationally. METHODS: An international, multicenter, observational, cross-sectional study was conducted over one calendar month in 2019. Participants were adults (≥18 years) with nontraumatic headache as the main presenting complaint. Exclusion criteria were recent head trauma, missing records, interhospital transfers, re-presentation with same headache as a recent visit, and headache as an associated symptom. Data collected included demographics, clinical assessment, investigation, treatment, and outcome. RESULTS: We enrolled 4536 patients (67 hospitals, 10 countries). "Thunderclap" onset was noted in 14.2% of cases (644/4536). Headache was rated as severe in 27.2% (1235/4536). New neurological examination findings were uncommon (3.2%; 147/4536). Head computed tomography (CT) was performed in 36.6% of patients (1661/4536), of which 9.9% showed clinically important pathology (165/1661). There was substantial variation in CT scan utilization between countries (15.9%-75.0%). More than 30 different diagnoses were made. Presumed nonmigraine benign headache accounted for 45.4% of cases (2058/4536) with another 24.3% classified as migraine (1101/4536). A small subgroup of patients have a serious secondary cause for their headache (7.1%; 323/4536) with subarachnoid hemorrhage (SAH), stroke, neoplasm, non-SAH intracranial hemorrhage/hematoma, and meningitis accounting for about 1% each. Most patients were treated with simple analgesics (paracetamol, aspirin, or nonsteroidal anti-inflammatory agents). Most patients were discharged home (83.8%; 3792/4526). In-hospital mortality was 0.3% (11/4526). CONCLUSION: Diagnosis and management of headache in the ED is challenging. A small group of patients have a serious secondary cause for their symptoms. There is wide variation in the use of neuroimaging and treatments. Further work is needed to understand the variation in practice and to better inform international guidelines regarding emergent neuroimaging and treatment.

The Headache in Emergency Departments study: Opioid prescribing in patients presenting with headache. A multicenter, cross-sectional, observational study.

OBJECTIVE: To describe the patterns of opioid use in patients presenting to the emergency department (ED) with nontraumatic headache by severity and geography. BACKGROUND: International guidelines recognize opioids are ineffective in treating primary headache disorders. Globally, many countries are experiencing an opioid crisis. The ED can be a point of initial exposure leading to tolerance for patients. More geographically diverse data are required to inform practice. METHODS: This was a planned, multicenter, cross-sectional, observational substudy of the international Headache in Emergency Departments (HEAD) study. Participants were prospectively identified throughout March 2019 from 67 hospitals in Europe, Asia, Australia, and New Zealand. Adult patients with nontraumatic headache were included as identified by the local site investigator. RESULTS: Overall, 4536 patients were enrolled in the HEAD study. Opioids were administered in 1072/4536 (23.6%) patients in the ED, and 386/3792 (10.2%) of discharged patients. High opioid use occurred prehospital in Australia (190/1777, 10.7%) and New Zealand (55/593, 9.3%). Opioid use in the ED was highest in these countries (Australia: 586/1777, 33.0%; New Zealand: 221/593, 37.3%). Opioid prescription on discharge was highest in Singapore (125/442, 28.3%) and Hong Kong (12/49, 24.5%). Independent predictors of ED opioid administration included the following: severe headache (OR 4.2, 95% CI 3.1-5.5), pre-ED opioid use (OR 1.42, 95% CI 1.11-1.82), and long-term opioid use (OR 1.80, 95% CI 1.26-2.58). ED opioid administration independently predicted opioid prescription at discharge (OR 8.4, 95% CI 6.3-11.0). CONCLUSION: Opioid prescription for nontraumatic headache in the ED and on discharge varies internationally. Severe headache, prehospital opioid use, and long-term opioid use predicted ED opioid administration. ED opioid administration was a strong predictor of opioid prescription at discharge. These findings support education around policy and guidelines to ensure adherence to evidence-based interventions for headache.

A European Research Agenda for Geriatric Emergency Medicine: a modified Delphi study.

PURPOSE: Geriatric Emergency Medicine (GEM) focuses on delivering optimal care to (sub)acutely ill older people. This involves a multidisciplinary approach throughout the whole healthcare chain. However, the underpinning evidence base is weak and it is unclear which research questions have the highest priority. The aim of this study was to provide an inventory and prioritisation of research questions among GEM professionals throughout Europe. METHODS: A two-stage modified Delphi approach was used. In stage 1, an online survey was administered to various professionals working in GEM both in the Emergency Department (ED) and other healthcare settings throughout Europe to make an inventory of potential research questions. In the processing phase, research questions were screened, categorised, and validated by an expert panel. Subsequently, in stage 2, remaining research questions were ranked based on relevance using a second online survey administered to the same target population, to identify the top 10 prioritised research questions. RESULTS: In response to the first survey, 145 respondents submitted 233 potential research questions. A total of 61 research questions were included in the second stage, which was completed by 176 respondents. The question with the highest priority was: Is implementation of elements of CGA (comprehensive geriatric assessment), such as screening for frailty and geriatric interventions, effective in improving outcomes for older patients in the ED? CONCLUSION: This study presents a top 10 of high-priority research questions for a European Research Agenda for Geriatric Emergency Medicine. The list of research questions may serve as guidance for researchers, policymakers and funding bodies in prioritising future research projects.

Epidemiology, treatment and outcome of patients with lower respiratory tract infection presenting to emergency departments with dyspnoea (AANZDEM and EuroDEM studies).

OBJECTIVE: Lower respiratory tract infection (LRTI) is a frequent cause of dyspnoea in EDs, and is associated with considerable morbidity and mortality. We described and compared the management of this disease in Europe and Oceania/South-East Asia (SEA) cohorts. METHODS: We conducted a prospective cohort study with three time points in Europe and Oceania/SEA. We included in this manuscript patients presenting to EDs with dyspnoea and a diagnosis of LRTI in ED. We collected comorbidities, chronic medication, clinical signs at arrival, laboratory parameters, ED management and patient outcomes. RESULTS: A total of 1389 patients were included, 773 in Europe and 616 in SEA. The European cohort had more comorbidities including chronic heart failure, obesity, chronic obstructive pulmonary disease and smoking. Levels of inflammatory markers were higher in Europe. There were more patients with inflammatory markers in Europe and more hypercapnia in Oceania/SEA. The use of antibiotics was higher in SEA (72.2% vs 61.8%, P < 0.001) whereas intravenous diuretics, non-invasive and invasive ventilation were higher in Europe. Intensive care unit admission rate was 9.9% in Europe cohort and 3.4% in Oceania/SEA cohort. ED mortality was 1% and overall in-hospital mortality was 8.7% with no differences between regions. CONCLUSIONS: More patients with LRTI in Europe presented with cardio-respiratory comorbidities, they received more adjunct therapies and had a higher intensive care unit admission rate than patients from Oceania/SEA, although mortality was similar between the two cohorts.

The factors predicting pneumonia in COVID-19 patients: preliminary results from a university hospital in Turkey

Background/aim: Pneumonia is the most serious clinical presentation of COVID-19. This study aimed to determine the demographic, clinical, and laboratory findings that can properly predict COVID-19 pneumonia. Materials and methods: This study was conducted in the Gazi University hospital. All hospitalized patients with confirmed and suspected SARS-CoV-2 infection between 16 March 2020 and 30 April 2020 were analyzed retrospectively. COVID-19 patients were separated into two groups, pneumonia and nonpneumonia, and then compared to determine predicting factors for COVID-19 pneumonia. Variables that had a P-value of less than 0.20 and were not correlated with each other were included in the logistic regression model. Results: Of the 247 patients included in the study 58% were female, and the median age was 40. COVID-19 was confirmed in 70.9% of these patients. Among the confirmed COVID-19 cases, 21.4% had pneumonia. In the multivariate analysis male sex (P = 0.028), hypertension (P = 0.022), and shortness of breath on hospital admission (P = 0.025) were significant factors predicting COVID-19 pneumonia. Conclusion: Shortness of breath, male sex, and hypertension were significant for predicting COVID-19 pneumonia on admission. Patients with these factors should be evaluated more carefully for diagnostic procedures, such as thorax CT.

Trends in medical students' career choice of emergency medicine: A 14-year study.

INTRODUCTION: The long-term trends of medical students' choice for emergency medicine (EM) in Turkey are unclear. With this background, we aimed to determine the change in the rate of EM preferences of students over the years. METHODS: This was a cross-sectional study originated from 6th-year medical students' feedback forms, to examine trends of EM carrier preferences between 2005 and 2018 in a tertiary care academic emergency department. There are two main questions containing "would you choose EM as a specialty?" and "why?" as open-ended questions in the form. The answers to the open-ended question were classified as six main factors, which were perception of work, lifestyle, nature of work, personal job preference, mentorship/department experiences, and income. RESULTS: During the study, 2957 forms (80.6% of 3668) were completed by 6th-year medical students. Of the students, 26.5% (n = 784) responded "yes" to the question, which was "would you choose EM as a specialty?," 6.1% (n = 181) responded "do not know," and 67.4% (n = 1992) responded "no." In 2005, 15% of students stated that they would choose EM, while this rate increased to 29% in 2018 (χ 2: 9.67; P trend = 0.003). Perception of work was the most common reason for "yes" (46.3%), "no" (46%), and "do not know" answers. CONCLUSION: The rate of EM choice of medical students doubled during the study, and approximately one in three students stated that they could choose EM as their future career in the past year. Perception of work was the main factor for choosing or rejecting to EM.

Seasonal variations of patients presenting dyspnea to emergency departments in Europe: Results from the EURODEM Study

Background/aim: To describe seasonal variations in epidemiology, management, and short-term outcomes of patients in Europe presenting to an emergency department (ED) with a main complaint of dyspnea. Materials and methods: Anobservational prospective cohort study was performed in 66 European EDs which included consecutive patients presenting to EDs with dyspnea as the main complaint during 3 72-h study periods. Data were collected on demographics, comorbidities, chronic treatment, prehospital treatment, mode of arrival of patient to ED, clinical signs at admission, treatment in the ED, ED diagnosis, discharge from ED, and in-hospital outcome. Results: The study included 2524 patients with a median age of 69 (53­80) years old. Of the patients presented, 991 (39.3%) were in autumn, 849 (33.6%) were in spring, and 48 (27.1%) were in winter. The winter population was significantly older (P < 0.001) and had a lower rate of ambulance arrival to ED (P < 0.001). In the winter period, there was a higher rate for lower respiratory tract infection (35.1%), and patients were more hypertensive, more hypoxic, and more hyper/hypothermic compared to other seasons. The ED mortality was about 1% and, in hospital, mortality for admitted patients was 7.4%. Conclusion: The analytic method and the outcome of this study may help to guide the allocation of ED resources more efficiently and to recommend seasonal ED management protocols based on the seasonal trend of dyspneic patients.

Get with the guidelines: management of chronic obstructive pulmonary disease in emergency departments in Europe and Australasia is sub-optimal.

BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are common in emergency departments (ED). Guidelines recommend administration of inhaled bronchodilators, systemic corticosteroids and antibiotics along with non-invasive ventilation (NIV) for patients with respiratory acidosis. AIM: To determine compliance with guideline recommendations for patients treated for COPD in ED in Europe (EUR) and South East Asia/Australasia (SEA) and to compare management and outcomes. METHODS: In each region, an observational prospective cohort study was performed that included patients presenting to ED with the main complaint of dyspnoea during three 72-h periods. This planned sub-study included those with an ED primary discharge diagnosis of COPD. Data were collected on demographics, clinical features, treatment, disposition and in-hospital mortality. We determined overall compliance with guideline recommendations and compared treatments and outcome between regions. RESULTS: A total of 801 patients was included from 122 ED (66 EUR and 46 SEA). Inhaled bronchodilators were administered to 80.3% of patients, systemic corticosteroids to 59.5%, antibiotics to 44 and 60.6% of patients with pH <7.3 received NIV. The proportion administered systemic corticosteroids was higher in SEA (EUR vs SEA for all comparisons; 52 vs 66%, P < 0.001) as was administration of antibiotics (40 vs 49%, P = 0.02). Rates of NIV and mechanical ventilation were similar. Overall in-hospital mortality was 4.2% (SEA 3.9% vs EUR 4.5%, P = 0.77). CONCLUSION: Compliance with guideline recommended treatments, in particular administration of corticosteroids and NIV, was sub-optimal in both regions. Improved compliance has the potential to improve patient outcome.
