Is it valid to assess an individual’s performance in team training simulation when the supporting team are confederates?: A controlled and randomized clinical trial

International audienceBackground: During simulation training, the confederate is a member of the pedagogical team. Its role is to facilitate the interaction between participants and the environment, and is thought to increase realism and immersion. Its influence on participants' performance in full-scale simulation remains however unknown. The purpose of this study was to observe the effect of the presence of confederates on the participants' performance during full-scale simulation of crisis medical situations. Methods: This was a prospective, randomized study comparing 2 parallel groups. Participants were emergency medicine residents engaging in a simulation session, with or without confederates. Participants were then evaluated on their Crisis Resource Management performance (CRM). The overall performance score on the Ottawa Global Rating Scale was assessed as primary outcome and the 5 non-technical CRM skills as secondary outcomes. Results: A total of 63 simulation sessions, including 63 residents, were included for statistical analysis (n = 32 for Control group and 31 for Confederate group). The mean Overall Performance score was 3.9 ± 0.8 in the Control group and 4.0 ± 1.1 in the Confederate group, 95% confidence interval of the difference [-0.6; 0.4], p = 0.60. No significant differences between the two groups were observed on each CRM items (leadership, situational awareness, communication, problem solving, resource utilization) Conclusion: In this randomized and controlled study, the presence of confederates during full-scale simulated practice of crisis medical situations does not seem to influence the CRM skills performance of Emergency medicine residents. Trial registration: This study does not need to be registered on Clintrial as it does not report a health care intervention on human participants

Hydroxyzine for lowering patient's anxiety during prehospital morphine analgesia: A prospective randomized double blind study

International audienceStudy objective: Hydroxyzine is an antihistamine drug used for symptomatic relief of anxiety and tension. We hypothesized that managing the anxiety of patients with severe pain by adding hydroxyzine to a conventional intravenous morphine titration would relieve their pain more effectively.Methods: This was a randomized, double-blind, controlled group study of prehospital patients with acute pain scored greater than or equal to 6 on a 0-10 verbal numeric rating scale (NRS). Patients'anxiety was measured with the self-reported Face Anxiety Scale (FAS) ranking from 0 to 4. The percentage of patients with pain relief (NRS score ≤ 3) 15 min after the first injection was the primary outcome.Results: One hundred forty patients were enrolled. Fifty-one percent (95% CI 39% to 63%) of hydroxyzine patients versus 52% (95% CI 40% to 64%) of placebo patients reported a pain numeric rating scale score of 3 or lower at 15 min. Ninety-one percent (95% CI 83% to 98%) of patients receiving hydroxyzine reported no more severe anxiety versus 78% (95% CI 68% to 88%) of patients with placebo (p > 0.05). Adverse events were minor, with no difference between groups (6% in hydroxyzine patients and 14% in placebo patients).Conclusion: Addition of hydroxyzine to morphine in the prehospital setting did not reduce pain or anxiety in patients with acute severe pain and therefore is not indicated based on our results

EPICANCER—Cancer Patients Presenting to the Emergency Departments in France: A Prospective Nationwide Study

Background: We aimed to estimate the prevalence of cancer patients who presented to Emergency Departments (EDs), report their chief complaint and identify the predictors of 30-day all-cause mortality. Patients and methods: we undertook a prospective, cross-sectional study during three consecutive days in 138 EDs and performed a logistic regression to identify the predictors of 30-day mortality in hospitalized patients. Results: A total of 1380 cancer patients were included. The prevalence of cancer patients among ED patients was 2.8%. The most frequent reasons patients sought ED care were fatigue (16.6%), dyspnea (16.3%), gastro-intestinal disorders (15.1%), trauma (13.0%), fever (12.5%) and neurological disorders (12.5%). Patients were admitted to the hospital in 64.9% of cases, of which 13.4% died at day 30. Variables independently associated with a higher mortality at day 30 were male gender (Odds Ratio (OR), 1.63; 95% CI, 1.04–2.56), fatigue (OR, 1.65; 95% CI, 1.01–2.67), poor performance status (OR, 3.00; 95% CI, 1.87–4.80), solid malignancy (OR, 3.05; 95% CI, 1.26–7.40), uncontrolled malignancy (OR, 2.27; 95% CI, 1.36–3.80), ED attendance for a neurological disorder (OR, 2.38; 95% CI, 1.36–4.19), high shock-index (OR, 1.80; 95% CI, 1.03–3.13) and oxygen therapy (OR, 2.68; 95% CI, 1.68–4.29). Conclusion: Cancer patients showed heterogeneity among their reasons for ED attendance and a high need for hospitalization and case fatality. Malignancy and general health status played a major role in the patient outcomes. This study suggests that the emergency care of cancer patients may be complex. Thus, studies to assess the impact of a dedicated oncology curriculum for ED physicians are warranted

Effect of an Emergency Department Care Bundle on 30-Day Hospital Discharge and Survival Among Elderly Patients With Acute Heart Failure: The ELISABETH Randomized Clinical Trial

International audienceKey PointsQuestionDoes an intervention aimed at improving guideline adherence for the management of acute heart failure, including intensive intravenous nitrate therapy and management of precipitating factors, improve hospital discharge and survival at 30 days?FindingsIn this stepped-wedge cluster randomized trial that included 503 patients 75 years and older who presented to the emergency department with acute heart failure, implementation of an early and comprehensive care bundle compared with usual care improved guideline adherence, but had no significant effect on number of days alive and out of hospital at 30 days (median of 19 d in both groups).MeaningsThis emergency department care bundle did not improve 30-day outcomes among older patients with acute heart failure. AbstractImportanceClinical guidelines for the early management of acute heart failure in the emergency department (ED) setting are based on only moderate levels of evidence, with subsequent low adherence to these guidelines.ObjectiveTo test the effect of an early guideline-recommended care bundle on short-term prognosis in older patients with acute heart failure in the ED.Design, Setting, and ParticipantsStepped-wedge cluster randomized trial in 15 EDs in France of 503 patients 75 years and older with a diagnosis of acute heart failure in the ED from December 2018 to September 2019 and followed up for 30 days until October 2019.InterventionsA care bundle that included early intravenous nitrate boluses; management of precipitating factors, such as acute coronary syndrome, infection, or atrial fibrillation; and moderate dose of intravenous diuretics (n = 200). In the control group, patient care was left to the discretion of the treating emergency physician (n = 303). Each center was randomized to the order in which they switched to the “intervention period.” After the initial 4-week control period for all centers, 1 center entered in the intervention period every 2 weeks.Main Outcomes and MeasuresThe primary end point was the number of days alive and out of hospital at 30 days. Secondary outcomes included 30-day all-cause mortality, 30-day cardiovascular mortality, unscheduled readmission, length of hospital stay, and kidney impairment.ResultsAmong 503 patients who were randomized (median age, 87 years; 298 [59%] women), 502 were analyzed. In the intervention group, patients received a median (interquartile range) of 27.0 (9-54) mg of intravenous nitrates in the first 4 hours vs 4.0 (2.0-6.0) mg in the control group (adjusted difference, 23.8 [95% CI, 13.5-34.1]). There was a significantly higher percentage of patients in the intervention group treated for their precipitating factors than in the control group (58.8% vs 31.9%; adjusted difference, 31.1% [95% CI, 14.3%-47.9%]). There was no statistically significant difference in the primary end point of the number of days alive and out of hospital at 30 days (median [interquartile range], 19 [0- 24] d in both groups; adjusted difference, −1.9 [95% CI, −6.6 to 2.8]; adjusted ratio, 0.88 [95% CI, 0.64-1.21]). At 30 days, there was no significant difference between the intervention and control groups in mortality (8.0% vs 9.7%; adjusted difference, 4.1% [95% CI, −17.2% to 25.3%]), cardiovascular mortality (5.0% vs 7.4%; adjusted difference, 2.1% [95% CI, −15.5% to 19.8%]), unscheduled readmission (14.3% vs 15.7%; adjusted difference, −1.3% [95% CI, −26.3% to 23.7%]), median length of hospital stay (8 d in both groups; adjusted difference, 2.5 [95% CI, −0.9 to 5.8]), and kidney impairment (1% in both groups).Conclusions and RelevanceAmong older patients with acute heart failure, use of a guideline-based comprehensive care bundle in the ED compared with usual care did not result in a statistically significant difference in the number of days alive and out of the hospital at 30 days. Further research is needed to identify effective treatments for acute heart failure in older patients.Trial Registration ClinicalTrials.gov Identifier: NCT0368321

Prise en charge des intoxications médicamenteuses et par drogues récréatives

Les intoxications représentent très probablement l’une des premières causes d’admission dans les services d’urgences et de réanimation. Un nombre important de bouleversements épidémiologiques est survenu au cours des dix dernières années, avec notamment la crise américaine des overdoses aux opioïdes et la diffusion exponentielle des nouvelles drogues festives de synthèse appelées nouvelles substances psychoactives (NPS). Les méthodes analytiques de screening et de dosage ont aussi connu des progrès techniques majeurs, donnant désormais la possibilité au médecin en charge du patient intoxiqué d’obtenir un diagnostic de certitude dans un délai de plus en plus court.

Management of pharmaceutical and recreational drug poisoning.

BACKGROUND: Poisoning is one of the leading causes of admission to the emergency department and intensive care unit. A large number of epidemiological changes have occurred over the last years such as the exponential growth of new synthetic psychoactive substances. Major progress has also been made in analytical screening and assays, enabling the clinicians to rapidly obtain a definite diagnosis. METHODS: A committee composed of 30 experts from five scientific societies, the Société de Réanimation de Langue Française (SRLF), the Société Française de Médecine d'Urgence (SFMU), the Société de Toxicologie Clinique (STC), the Société Française de Toxicologie Analytique (SFTA) and the Groupe Francophone de Réanimation et d'Urgences Pédiatriques (GFRUP) evaluated eight fields: (1) severity assessment and initial triage; (2) diagnostic approach and role of toxicological analyses; (3) supportive care; (4) decontamination; (5) elimination enhancement; (6) place of antidotes; (7) specificities related to recreational drug poisoning; and (8) characteristics of cardiotoxicant poisoning. Population, Intervention, Comparison, and Outcome (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. Analysis of the literature and formulation of recommendations were then conducted according to the GRADE® methodology. RESULTS: The SRLF-SFMU guideline panel provided 41 statements concerning the management of pharmaceutical and recreational drug poisoning. Ethanol and chemical poisoning were excluded from the scope of these recommendations. After two rounds of discussion and various amendments, a strong consensus was reached for all recommendations. Six of these recommendations had a high level of evidence (GRADE 1±) and six had a low level of evidence (GRADE 2±). Twenty-nine recommendations were in the form of expert opinion recommendations due to the low evidences in the literature. CONCLUSIONS: The experts reached a substantial consensus for several strong recommendations for optimal management of pharmaceutical and recreational drug poisoning, mainly regarding the conditions and effectiveness of naloxone and N-acetylcystein as antidotes to treat opioid and acetaminophen poisoning, respectively

Study protocol for investigating the performance of an automated blood test measuring GFAP and UCH-L1 in a prospective observational cohort of patients with mild traumatic brain injury: European BRAINI study

Introduction Mild traumatic brain injury (mTBI) is a common cause of clinical consultation in the emergency department. Patients with mTBI may undergo brain CT scans based on clinical criteria. However, the proportion of patients with brain lesions on CT is very low. Two serum biomarkers, glial fibrillar acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), have been shown to discriminate patients regarding the presence or absence of brain lesions on initial CT scan when assessed within the first 12 hours after TBI. However, the current technique for measuring serum concentrations of GFAP and UCH-L1 is manual and time consuming, which may hinder its use in routine clinical practice. This study assesses the diagnostic accuracy of an automated assay for the measurement of serum GFAP and UCH-L1 in a cohort of patients with mTBI who received a CT scan as the standard of care.Methods and analysis This is a prospective multicentre observational study of 1760 patients with mTBI recruited in France and Spain across 16 participating sites. Adult patients with an initial Glasgow Coma Scale score of 13–15 and a brain CT scan underwent blood sampling within 12 hours after TBI. The primary outcome measure is the diagnostic performance of an automated assay measuring serum concentrations of GFAP and UCH-L1 for discriminating between patients with positive and negative findings on brain CT-scans. Secondary outcome measures include the performance of these two biomarkers in predicting the neurological status and quality of life at 1 week and 3 months after the trauma.Ethics and dissemination Ethics approval was obtained by the Institutional Review Board of Sud-Ouest Outre Mer III in France (Re#2019-A01525-52) and Hospital 12 de Octubre in Spain (Re#19/322). The results will be presented at scientific meetings and published in peer-reviewed publications.Trial registration number ClinicalTrials.gov: NCT04032509

Variability in the indication of brain CT scan after mild traumatic brain injury. A transnational survey

Purpose: Clinical guidelines have been developed to standardize the management of mild traumatic brain injury (mTBI) in the emergency room, in particular the indication of brain CT scan and the use of blood biomarkers. The objective of this study was to determine the degree of adherence to guidelines in the management of these patients across four countries of Southern Europe. Methods: An electronic survey including structural and general management of mTBI patients and six clinical vignettes was conducted. In-charge physicians from France, Spain, Greece and Portugal were contacted by telephone and email. Diferences among countries were searched using an unconditional approach test on contingency tables. Results: One hundred and eighty eight physicians from 131 Hospitals (78 Spain, 36 France, 12 Greece and 5 Portugal) completed the questionnaire. There were diferences regarding the in-charge specialist across these countries. There was variability in the use of guidelines and their adherence. Spain was the country with the least guideline adherence. There was a global agreement in ordering a brain CT for patients receiving anticoagulation or platelet inhibitors, and for patients with seizures, altered consciousness, neurological defcit, clinical signs of skull fracture or signs of facial fracture. Aging was not an indication for CT in French centres. Loss of consciousness and posttraumatic amnesia were considered as indications for CT more frequently in Spain than in France. These fndings were in line with the data from the 6 clinical vignettes. The estimated use of CT reached around 50% of mTBI cases. The use of S100B is restricted to fve French centres. Conclusions: There were large variations in the guideline adherence, especially in the situations considered to order brain CT after mTBI
