Multidisciplinary support for ethics deliberations during the first COVID wave.

BACKGROUND: The first COVID-19 wave started in February 2020 in France. The influx of patients requiring emergency care and high-level technicity led healthcare professionals to fear saturation of available care. In that context, the multidisciplinary Ethics-Support Cell (EST) was created to help medical teams consider the decisions that could potentially be sources of ethical dilemmas. OBJECTIVES: The primary objective was to prospectively collect information on requests for EST assistance from 23 March to 9 May 2020. The secondary aim was to describe the Cell's functions during that period. RESEARCH DESIGN: This observational, real-time study of requests for Cell consultations concerned ethical dilemmas arising during a public health crisis. The EST created a grid to collect relevant information (clinical, patient's/designated representative's preferences and ethical principles strained by the situation), thereby assuring that each EST asked the same questions, in the same order. PARTICIPANTS AND RESEARCH CONTEXT: Only our university hospital's clinicians could request EST intervention. ETHICAL CONSIDERATIONS: The hospital Research Ethics Committee approved this study (no. CER-2020-107). The patient, his/her family, or designated representative was informed of this ethics consultation and most met with EST members, which enabled them to express their preferences and/or opposition. FINDINGS/RESULTS: 33 requests (patients' mean age: 80.8 years; 29 had COVID-19: 24 with dyspnea, 30 with comorbidities). 17 Emergency Department solicitations concerned ICU admission, without reference to resource constraints; others addressed therapeutic proportionality dilemmas. DISCUSSION: Intervention-request motives concerned limited resources and treatment intensity. Management revolved around three axes: the treatment option most appropriate for the patient, the feasibility of implementation, and dignified care for the patient. CONCLUSIONS: COVID-19 crisis forced hospitals to envisage prioritization of ICU access. Established decision-making criteria and protocols do not enable healthcare professionals to escape ethical dilemmas. That acknowledgement highlights ethical risks, enhances the added-value of nursing and encourages all players to be vigilant to pursue collective deliberations to achieve clear and transparent decisions.

Admission decisions to intensive care units in the context of the major COVID-19 outbreak: local guidance from the COVID-19 Paris-region area.

SARS-CoV-2 has caused a global pandemic unprecedented in size, spread, severity, and mortality. The influx of patients with severe or life-threatening disease means that in some cases, the available medical resources are not sufficient to meet the needs of all patients. Hence, healthcare providers may be forced to make difficult choices about which patients should be referred to the ICU. This document is intended to provide conceptual support to all healthcare teams currently engaged in the frontline management of the COVID-19 pandemic. It aims to assist physicians in the decision-making process for ICU admission and to help them provide uninterrupted and high-quality care.

General practitioner consultation after a visit to the emergency department: an observational study.

BACKGROUND: Some studies have demonstrated an association between poor continuity of care, high likelihood of 'inappropriate' use of emergency departments (EDs) and avoidable hospitalization. However, we lack data concerning primary care use after an ED visit. OBJECTIVE: Identify the determinants of a visit to the general practitioner (GP) after an ED visit.Methods. DESIGN: Observational study (single-centre cohort). SETTING: One emergency department in Paris, France. SUBJECTS: All adult patients who presented at the ED and were discharged. MAIN OUTCOME MEASURE: We collected data by the use of a standardized questionnaire, patients' medical records and a telephonic follow-up. Descriptive analyses were performed to compare individuals with and without a GP. Then, for those with a GP, multivariate logistic regression was used to identify the determinants of the GP consultation. RESULTS: We included 243 patients (mean age 45 years [±19]); 211 (87%) reported having a GP. Among those who reported having a GP, 52% had consulted their GP after the ED visit. Not having a GP was associated with young age, not having complementary health insurance coverage, and being single. GP consultation was associated with increasing age [adjusted odds ratios (aOR) = 1.03], poor self-reported health status (aOR = 2.25), medical complaints versus traumatic injuries (aOR = 2.24) and prescription for sick note (aOR = 5.74). CONCLUSION: Not having a GP was associated with factors of social vulnerability such as not having complementary health insurance coverage. For patients with a GP, consultation in the month after an ED visit seems appropriate, because it was associated with poor health status and medical complaints.

Methodological characteristics of randomized controlled trials of ultrasonography in emergency medicine.

INTRODUCTION: Interest in ultrasonography in emergency medicine has increased in recent years, as reflected by a marked increase in publications on the topic. The aim of this study was to 1) describe and evaluate methodological characteristics of randomized controlled trials (RCTs) evaluating an ultrasound intervention in emergency department and 2) estimate whether the reports adequately described the intervention to allow replication. METHODS: We searched MEDLINE via PubMed for RCTs published in 2015 assessing an ultrasound intervention, regardless of type, that were performed in an emergency department or evaluated in an emergency situation. Two researchers independently screened titles, abstracts and full texts. Data from all included studies were independently extracted. The Cochrane Collaboration Risk of Bias tool was used to assess risk of bias of reports, and the intervention reporting was evaluated by using the Template for Intervention Description and Replication checklist. RESULTS: We identified 11 reports. The most frequent topic was vascular access/identification (n = 4). Random sequence generation and allocation concealment were performed correctly in 55% and 27% trials. Three quarters of reports (73%) showed improper reporting or absence of participant blinding. Risk of bias due to assessor blinding was rated low for 3 RCTs (27%), risk of attrition bias low for all reports, and risk of selective outcome reporting unclear for most reports (n = 10). Only 3 reports (27%) provided an optimal description of the intervention. CONCLUSION: The quality of these trials raises questions. In our sample, the authors did not correctly report blinding of participants and assessors or allocation concealment.

Prognosis of cirrhotic patients admitted to Emergency Departments: A multicenter study.

OBJECTIVES: Life threatening complications can occur at any stage of cirrhosis progression. There are few studies on the prognosis of cirrhotic patients managed in an Emergency Department (ED) although management of patients will occur in the ED. The objective of our study was to determine the risk factors for mortality in cirrhotic patients who visited to the ED. METHODS: All cirrhotic patients attending ED in three different university hospitals of Assistance Publique - Hôpitaux de Paris between January 2014 and June 2015 were identified by a retrospective analysis of digital records and included in the study. The primary end-point was 30-day mortality in all cirrhotic patients who visited the ED. RESULTS: A total of 609 ED visits were analyzed among 224 patients: 115 (51%) presented a cirrhosis of alcoholic origin, 43 (19%) were caused by Hepatitis C, 28 (13%) of mixed origin (viral and alcoholic), 17 (8%) were caused by Hepatitis B and 21 (9%) of other origins. Fifty-five (25%) of these patients died within 30 days of their initial presentation to the ED. In multivariate analysis, the age (Odds Ratio: 1.04 [1.01-1.07]), cirrhosis associated with hepatocellular carcinoma (OR: 3.07 [1.37-6.91]), serum creatinine at admission (OR: 1.01 [1.01-1.02]), serum bilirubin at admission (OR: 1.01 [1.01-1.02]) and health impairment (OR: 2.57 [1.28-5.16]) were associated with mortality. CONCLUSIONS: The mortality rate of cirrhotic patients attending an ED was high. The prognosis of cirrhotic patients admitted to the ED depended on the severity of the liver and other organ dysfunction. The presence of a hepatocellular carcinoma on admission was also a risk factor for death.

Targeted HIV Screening in Eight Emergency Departments: The DICI-VIH Cluster-Randomized Two-Period Crossover Trial.

STUDY OBJECTIVE: This study compares the effectiveness and cost-effectiveness of nurse-driven targeted HIV screening alongside physician-directed diagnostic testing (intervention strategy) with diagnostic testing alone (control strategy) in 8 emergency departments. METHODS: In this cluster-randomized, 2-period, crossover trial, 18- to 64-year-old patients presenting for reasons other than potential exposure to HIV were included. The strategy applied first was randomly assigned. During both periods, diagnostic testing was prescribed by physicians following usual care. During the intervention periods, patients were asked to complete a self-administered questionnaire. According to their answers, the triage nurse suggested performing a rapid test to patients belonging to a high-risk group. The primary outcome was the proportion of new diagnoses among included patients, which further refers to effectiveness. A secondary outcome was the intervention's incremental cost (health care system perspective) per additional diagnosis. RESULTS: During the intervention periods, 74,161 patients were included, 16,468 completed the questionnaire, 4,341 belonged to high-risk groups, and 2,818 were tested by nurses, yielding 13 new diagnoses. Combined with 9 diagnoses confirmed through 97 diagnostic tests, 22 new diagnoses were established. During the control periods, 74,166 patients were included, 92 were tested, and 6 received a new diagnosis. The proportion of new diagnoses among included patients was higher during the intervention than in the control periods (3.0 per 10,000 versus 0.8 per 10,000; difference 2.2 per 10,000, 95% CI 1.3 to 3.6; relative risk 3.7, 95% CI 1.4 to 9.8). The incremental cost was €1,324 per additional new diagnosis. CONCLUSION: The combined strategy of targeted screening and diagnostic testing was effective.

Effect of Systematic Intensive Care Unit Triage on Long-term Mortality Among Critically Ill Elderly Patients in France: A Randomized Clinical Trial.

Importance: The high mortality rate in critically ill elderly patients has led to questioning of the beneficial effect of intensive care unit (ICU) admission and to a variable ICU use among this population. Objective: To determine whether a recommendation for systematic ICU admission in critically ill elderly patients reduces 6-month mortality compared with usual practice. Design, Setting, and Participants: Multicenter, cluster-randomized clinical trial of 3037 critically ill patients aged 75 years or older, free of cancer, with preserved functional status (Index of Independence in Activities of Daily Living ≥4) and nutritional status (absence of cachexia) who arrived at the emergency department of one of 24 hospitals in France between January 2012 and April 2015 and were followed up until November 2015. Interventions: Centers were randomly assigned either to use a program to promote systematic ICU admission of patients (n=1519 participants) or to follow standard practice (n=1518 participants). Main Outcomes and Measures: The primary outcome was death at 6 months. Secondary outcomes included ICU admission rate, in-hospital death, functional status, and quality of life (12-Item Short Form Health Survey, ranging from 0 to 100, with higher score representing better self-reported health) at 6 months. Results: One patient withdrew consent, leaving 3036 patients included in the trial (median age, 85 [interquartile range, 81-89] years; 1361 [45%] men). Patients in the systematic strategy group had an increased risk of death at 6 months (45% vs 39%; relative risk [RR], 1.16; 95% CI, 1.07-1.26) despite an increased ICU admission rate (61% vs 34%; RR, 1.80; 95% CI, 1.66-1.95). After adjustments for baseline characteristics, patients in the systematic strategy group were more likely to be admitted to an ICU (RR, 1.68; 95% CI, 1.54-1.82) and had a higher risk of in-hospital death (RR, 1.18; 95% CI, 1.03-1.33) but had no significant increase in risk of death at 6 months (RR, 1.05; 95% CI, 0.96-1.14). Functional status and physical quality of life at 6 months were not significantly different between groups. Conclusions and Relevance: Among critically ill elderly patients in France, a program to promote systematic ICU admission increased ICU use but did not reduce 6-month mortality. Additional research is needed to understand the decision to admit elderly patients to the ICU. Trial Registration: clinicaltrials.gov Identifier: NCT01508819.

Participation of general practitioners in the management of their "hospital at home" patients / Participation des médecins généralistes dans les prises en charge de leurs patients en hospitalisation à domicile.

Objectives: Hospital at home (HAH) care is becoming increasingly popular in France and requires the involvement of general practitioners (GPs) in the care of their patients. The objective of this study was to identify the incentives and barriers to the involvement of general practitioners in HAH. Materials and methods: A qualitative study was carried out using semi-structured interviews during a focus group with 12 GPs. All interviews were recorded and then transcribed verbatim and data analysis used the grounded theory method. Results: General practitioners appeared to be familiar with the indications and places of care for HAH, but they highlighted the difficulties associated with the HAH request circuit. GPs identified difficulties determining their exact role in HAH, which were improved by their clinical expertise in home visits. Doctors stressed the complexity of home care, but they were assisted by the coordinating physician and they requested specific training. Conclusion: We identified incentives and barriers to the participation of GPs in HAH. The request circuit needs to be simplified, home visits need to be strengthened and support must be provided to GPs in their management of complex care.

[Improving emergency department organisation]. / Comment améliorer le fonctionnement des structures d'urgences?

Emergency departments use has been constantly increasing over the world. Overcrowding is defined as a situation which compromises patient safety because of delayed cares. This situation is often reached. Emergency departments have to continuously improve their organization to be able to ensure the same quality of care to a higher number of patients. Thus a good organization is essential: it doesn't always avoid overcrowding. The rest of the hospital has to be involved in this process to ensure efficiency. We examine the various interventions and procedures that can be found in medical literature for improving patients flow and management in emergency departments.

Impact on 6-month outcomes of hospital trajectory in critically ill older patients: analysis of the ICE-CUB2 clinical trial.

BACKGROUND: Little is known about the impact of hospital trajectory on survival and functional decline of older critically ill patients. We evaluate 6-month outcomes after admission to: intensive care units (ICU), intermediate care units (IMCU) or acute medical wards (AMW). METHODS: Data from the randomised prospective multicentre clinical trial ICE-CUB2 was secondarily analysed. Inclusion criteria were: presenting at emergency departments in critical condition; age ≥ 75 years; activity of daily living (ADL) ≥ 4; preserved nutritional status; and no active cancer. A Cox model was fitted to compare survival according to admission destination adjusting for patient characteristics. Sensitivity analysis using multiple imputation for missing data and propensity score matching were performed. RESULTS: Among 3036 patients, 1675 (55%) were women; median age was 85 [81-99] years; simplified acute physiology score (SAPS-3) 62 [55-69]; 1448 (47%) were hospitalised in an ICU, 504 in IMCU (17%), and 1084 (36%) in AMW. Six-month mortality was 629 (44%), 155 (31%) and 489 (45%) after admission in an ICU, IMCU and AMW (p < 0.001), respectively. In multivariate analysis, AMW admission was associated with worse 6-month survival (HR 1.31, 95% CI 1.04-1.63) in comparison with IMCU admission, after adjusting for age, gender, comorbidities, ADL, SAPS-3 and diagnosis. Survival was not significantly different between patients admitted in an ICU and an IMCU (HR 1.17, 95% CI 0.95-1.46). Sensitivity analysis using multiple imputation for missing data and propensity score matching found similar results. Hospital destination was not significantly associated with the composite criterion loss of 1-point ADL or mortality. Physical and mental components of the 12-Item Short-Form Health Survey were significantly lower in the acute medical ward group (34.3 [27.5-41.7], p = 0.037 and 44.3 [38.6-48.6], p = 0.028, respectively) than in the ICU group (34.7 [28.4-45.3] and 45.5 [40.0-50.0], respectively) and IMCU group (35.7 [29.7-43.8] and 44.5 [39.7-48.4], respectively). CONCLUSIONS: Admission in an AMW was associated with worse 6-month survival in older critically ill patients in comparison with IMCU admission, with no difference of survival between ICU and IMCU admission. There were no clinically relevant differences in quality of life in each group. These results should be confirmed in specific studies and raise the question of dedicated geriatric IMCUs.

Erythromycin infusion or gastric lavage for upper gastrointestinal bleeding: a multicenter randomized controlled trial.

STUDY OBJECTIVE: The quality of endoscopy depends on the quality of upper gastrointestinal tract preparation. We determine whether in acute upper gastrointestinal bleeding the frequency of satisfactory stomach visualization was different after intravenous erythromycin, a nasogastric tube with gastric lavage, or both. METHODS: We performed a prospective, randomized, multicenter (6 emergency departments) study in patients with acute upper gastrointestinal bleeding presenting with hematemesis or melena. The patients were randomized into 3 groups: (1) intravenous erythromycin infusion without nasogastric tube placement (erythromycin group), (2) nasogastric tube placement without erythromycin (nasogastric group), and (3) intravenous erythromycin infusion combined with nasogastric tube placement (nasogastric-erythromycin group). The main outcome measure was the proportion of satisfactory stomach visualization. RESULTS: Two hundred fifty-three patients (181 men, mean age 61 years [SD 15 years], 84 with cirrhosis) were randomized: 84 (erythromycin group), 85 (nasogastric group), and 84 (nasogastric-erythromycin group). Overall, there was 85% satisfactory stomach visualization; between-group differences were not significant: -4% (95% confidence interval [CI] -15% to 6%) for the erythromycin group and nasogastric-erythromycin group, 2% (95% CI -14% to 9%) for the erythromycin group and nasogastric group, and -6.5% (95% CI -17% to 4%) for the nasogastric group and nasogastric-erythromycin group. The duration of the endoscopic procedure, rebleeding frequency, the need for a second endoscopy, the number of transfused blood units, and mortality at days 2, 7, and 30 did not differ significantly between groups. CONCLUSION: In acute upper gastrointestinal bleeding, administration of intravenous erythromycin provides satisfactory endoscopic conditions, without the need for a nasogastric tube and gastric lavage.

Anxiety and depression are unrecognised in emergency patients admitted to the observation care unit.

OBJECTIVE: To assess the sensitivity and specificity of emergency physicians in detecting anxiety and depression in patients requiring admission to the emergency department (ED) observation care unit for complementary investigations/treatment. METHODS: 339 consecutive patients admitted to the emergency observation care unit of 14 EDs were interviewed with standardised questionnaires. The characteristics of the patients, EDs and attending ED physicians were collected. Patients' anxiety and depression were identified using the Hospital Anxiety and Depression Scale (HADS), a self-administered questionnaire. ED physicians were blind to the HADS score and were asked to declare whether they perceived anxiety and depression in each patient. The judgement of ED physicians and the HADS score were compared using sensitivity, specificity, positive and negative likelihood ratios. RESULTS: The HADS questionnaire was correctly completed by 310 patients who comprised the study population. HADS detected symptoms of anxiety in 148 patients (47%) and symptoms of depression in 70 patients (23%). ED physicians determined the presence or absence of anxiety with a sensitivity of 48% (95% CI 40% to 56%) and a specificity of 69% (95% CI 61% to 75%). Positive and negative likelihood ratios were 1.54 (95% CI 1.16 to 2.06) and 0.75 (95% CI 1.28 to 3.28) for anxiety. They detected the presence or absence of depression with a sensitivity of 39% (95% CI 28% to 51%) and a specificity of 78% (95% CI 72% to 83%). Positive and negative likelihood ratios were 1.75 (95% CI 1.20 to 2.56) and 0.78 (95% CI 1.26 to 3.87) for depression. CONCLUSION: Although patients presenting to the ED often experience anxiety and depression, these symptoms are poorly detected by ED physicians.

Blood product needs and transfusion timelines for the multisite massive Paris 2015 terrorist attack: A retrospective analysis.

OBJECTIVE: Hemorrhage is the leading cause of death after terrorist attack, and the immediacy of labile blood product (LBP) administration has a decisive impact on patients' outcome. The main objective of this study was to evaluate the transfusion patterns of the Paris terrorist attack victims, November 13, 2015. METHODS: We performed a retrospective analysis including all casualties admitted to hospital, aiming to describe the transfusion patterns from admission to the first week after the attack. RESULTS: Sixty-eight of 337 admitted patients were transfused. More than three quarters of blood products were consumed in the initial phase (until November 14, 11:59 PM), where 282 packed red blood cell (pRBC) units were transfused along with 201 plasma and 25 platelet units, to 55 patients (16% of casualties). Almost 40% of these LBPs (134 pRBC, 73 plasma, 8 platelet units) were transfused within the first 6 hours after the attack. These early transfusions were massive transfusion (MT) for 20 (6%) of 337 patients, and the average plasma/red blood cell ratio was 0.8 for MT patients who received 366 (72%) of 508 LBPs.The median time from admission to pRBC transfusion was 57 (25-108) minutes and 208 (52-430) minutes for MT and non-MT patients, respectively. These same time intervals were 119 (66-202) minutes and 222 (87-381) minutes for plasma and 225 (131-289) minutes and 198 (167-230) minutes for platelets. CONCLUSION: Our data suggest that improving transfusion procedures in mass casualty setting should rely more on shortening the time to bring LBP to the bedside than in increasing the stockpile. LEVEL OF EVIDENCE: Epidemiological study, Therapeutic IV.

Selection of intensive care unit admission criteria for patients aged 80 years and over and compliance of emergency and intensive care unit physicians with the selected criteria: An observational, multicenter, prospective study.

OBJECTIVE: To describe intensive care unit referral decisions by emergency room physicians in patients aged > or =80 yrs. DESIGN: Prospective, observational cohort study of patients aged > or =80 yrs who were triaged in the emergency room, using a list of intensive care unit admission criteria selected by emergency physicians among 76 preliminary criteria adapted from the 1999 Society of Critical Care Medicine guidelines. The Delphi method was used to select the criteria. SETTING: Fifteen French hospitals. PATIENTS: A total of 2646 patients aged > or =80 yrs with at least one criterion. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: In the Delphi process, level of agreement was assessed as follows: when all answers fell within a single interval (7-9 = definite admission criteria; 4-6 = equivocal admission criteria or 1-3 = inappropriate admission), agreement was strong; when answers spanned two intervals, agreement was fair; and when answers spanned all three intervals, agreement was poor. Of the 76 preliminary criteria, two were removed; 44 were selected as definite intensive care unit admission criteria; and 30 were selected as equivocal intensive care unit admission criteria. Of the 1426 patients meeting definite admission criteria, 441 (30.9%) were referred for intensive care unit admission and 231 of 441 (52.4%) were admitted to the intensive care unit. Of the 1041 patients with equivocal admission criteria, 181 (17.3%) were referred for intensive care unit admission; and, of these, 79 (43.6%) were admitted to the intensive care unit. Factors associated independently with no intensive care unit referral were age odds ratio [OR], 1.04; 95% confidence interval [CI], 1.04-1.07), active cancer (OR, 1.61; 95% CI, 1.09-1.38), unknown hospitalization status (OR, 1.53; 95% CI, 1.11-2.11), unknown living arrangements (OR, 1.69; 95% CI, 1.19-2.42), regular psychotropic medications (OR, 1.42; 95% CI, 1.10-1.81), low severity at referral (OR, 0.60; 95% CI, 0.53-0.68), low activity in daily living score (OR, 0.93; 95% CI, 0.88-0.99). CONCLUSIONS: Emergency and intensive care unit physicians were extremely reluctant to consider intensive care unit admission of patients aged > or =80 yrs, despite the presence of criteria indicating that intensive care unit admission was certainly or possibly appropriate.

A systematic review of retracted publications in emergency medicine.

The objective of this study was to characterize retracted publications in emergency medicine. We searched MEDLINE, Web of Science and Cochrane Central Register of Controlled Trials to identify all retracted publications in the field of emergency medicine. We also searched an independent website that reports and archives retracted scientific publications. Two researchers independently screened titles, abstracts and full text of search results. Data from all included studies were then independently extracted. We identified 28 retraction notes. Eleven (39%) articles were published by authors from Europe. The oldest retracted article was published in 2001. The 28 retracted papers were published by 22 different journals. Two authors were named on multiples retractions. The median impact factor of journals was 1.03 (0.6-1.9). Almost all studies were available online [26/28 (93%)], but only 40% had watermarking on the article. The retraction notification was available for all articles. Three (11%) retraction notices did not clearly report the retraction reasons, and most retraction notices were issued by the editors [14 (56%)]. The most frequent retraction reasons were plagiarism [eight (29%)], duplicate publication [three (11%)] and overlap [two (2%)]. Retracted articles were cited on average 14 times. In most cases, the retraction cause did not invalidate the study's results [17 (60%)]. The most common reason for retraction was related to a misconduct by the authors. These results can question the necessity to normalize retraction procedures among the large number of biomedical editors and to educate future researchers on research integrity.

Analysis of the medical response to November 2015 Paris terrorist attacks: resource utilization according to the cause of injury.

PURPOSE: The majority of terrorist acts are carried out by explosion or shooting. The objective of this study was first, to describe the management implemented to treat a large number of casualties and their flow together with the injuries observed, and second, to compare these resources according to the mechanism of trauma. METHODS: This retrospective cohort study collected medical data from all casualties of the attacks on November 13th 2015 in Paris, France, with physical injuries, who arrived alive at any hospital within the first 24 h after the events. Casualties were divided into two groups: explosion injuries and gunshot wounds. RESULTS: 337 casualties were admitted to hospital, 286 (85%) from gunshot wounds and 51 (15%) from explosions. Gunshot casualties had more severe injuries and required more in-hospital resources than explosion casualties. Emergency surgery was required in 181 (54%) casualties and was more frequent for gunshot wounds than explosion injuries (57% vs. 35%, p < 0·01). The types of main surgery needed and their delay following hospital admission were as follows: orthopedic [n = 107 (57%); median 744 min]; general [n = 27 (15%); 90 min]; vascular [n = 19 (10%); median 53 min]; thoracic [n = 19 (10%); 646 min]; and neurosurgery [n = 4 (2%); 198 min]. CONCLUSION: The resources required to deal with a terrorist attack vary according to the mechanism of trauma. Our study provides a template to estimate the proportion of various types of surgical resources needed overall, as well as their time frame in a terrorist multisite and multitype attack.

Glucocorticoids for acute urticaria: study protocol for a double-blind non-inferiority randomised controlled trial.

INTRODUCTION: This study protocol describes a trial designed to investigate whether antihistamine alone in patients with acute urticaria does not increase the 7-day Urticaria Activity Score (UAS7) in comparison with an association of antihistamine and glucocorticoids and reduces short-term relapses and chronic-induced urticaria. METHODS AND ANALYSIS: This is a prospective, double-blind, parallel-group, multicentre non-inferiority randomised controlled trial. Two-hundred and forty patients with acute urticaria admitted to emergency department will be randomised in a 1:1 ratio to receive levocetirizine or an association of levocetirizine and prednisone. Randomisation will be stratified by centre. The primary outcome will be the UAS7 at day 7. The secondary outcomes will encompass recurrence of hives and/or itch at day 7; occurrence of spontaneous hives or itch for >6 weeks; patients with angioedema at day 7, and 2, 6, 12 and 24 weeks; new emergency visits for acute urticaria recurrences at days 7 and 14, and 3 months; Dermatology Life Quality Index at days 7 and 14, and 3 and 6 months; and Chronic Urticaria Quality of Life Questionnaire at 6 weeks. ETHICS AND DISSEMINATION: The protocol has been approved by the Comité de Protection des PersonnesSud-Méditerranée II and will be carried out in accordance with the Declaration of Helsinki and Good Clinical Practice guidelines. A steering committee will oversee the progress of the study. Findings will be disseminated through national and international scientific conferences and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03545464.
