Targeted prophylactic anticoagulation based on the TRiP(cast) score in patients with lower limb immobilisation: a multicentre, stepped wedge, randomised implementation trial.

Background: Prophylactic anticoagulation in emergency department patients with lower limb trauma requiring immobilisation is controversial. The Thrombosis Risk Prediction for Patients with Cast Immobilisation-TRiP(cast)-score could identify a large subgroup of patients at low risk of venous thromboembolism for whom prophylactic anticoagulation can be safely withheld. We aimed to prospectively assess the safety of withholding anticoagulation for patients with lower limb trauma at low risk of venous thromboembolism, defined by a TRiP(cast) score of less than 7.

Effectiveness of a multimodal intervention to improve blood culture collection in an adult emergency department.

We investigated the impact of a multimodal intervention to improve the compliance of BC collections as a composite outcome, taking into account both blood volume collected and absence of solitary BC. We performed a quasi-experimental study using a before-after design (5 months for pre- and post-intervention evaluation) in an adult emergency department at a tertiary care hospital that showed that a multimodal intervention was associated with a dramatic increase in the proportion of blood cultures that were collected as recommended per national guidelines, from 17.3% (328/1896) to 68.

Out-of-Hospital Cardiac Arrest Detection by Machine Learning Based on the Phonetic Characteristics of the Caller's Voice.

Introduction: Out-of-hospital cardiac arrest (OHCA) is a major public health issue. The prognosis is closely related to the time from collapse to return of spontaneous circulation. Resuscitation efforts are frequently initiated at the request of emergency call center professionals who are specifically trained to identify critical conditions over the phone.

Ground-level falls among nonagenarians: the impact of pre-injury antithrombotic therapy.

Among nonagenarians admitted to our emergency department (ED) for ground-level falls, we assessed the impact of pre-injury antithrombotic (AT) treatment on the post-traumatic consequences, and identified risk factors for 1-month mortality. All eligible patients were consecutively included over an 18-month period. Head trauma was attested by reliable medical history, witnesses or recent external signs.

Evaluation of HEAR score to rule-out major adverse cardiac events without troponin test in patients presenting to the emergency department with chest pain.

Background And Importance: Current guidelines for patients presenting to the emergency department with chest pain without ST-segment elevation myocardial infarction (non-STEMI) on electrocardiogram are based on troponin measurement. The HEART score is reportedly a reliable work-up strategy that combines clinical evaluation with troponin value. A clinical rule that could select very low-risk patients without the need for a blood test (HEAR score, being the HEART score without the troponin item) would be of great interest.

Analysis of the Feasibility of a Vaccination Campaign against Influenza Epidemic and COVID-19 Pandemic in French Emergency Departments: A National Survey.

Background: Vaccination is one of the most effective ways to fight the influenza epidemic and the coronavirus disease 2019 (COVID-19) pandemic, which represent a major public issue. The objective was to investigate the adherence of heads of French emergency departments (ED) and nursing departments on a potential vaccination campaign of healthcare workers (HCW) and patients in ED.

Method: In February 2021, ED and nursing department heads were asked to answer a national survey.

Inter-hospital transport of critically ill patients to manage the intensive care unit surge during the COVID-19 pandemic in France.

Background: The COVID-19 pandemic led authorities to evacuate via various travel modalities critically ill ventilated patients into less crowded units. However, it is not known if interhospital transport impacts COVID-19 patient's mortality in intensive care units (ICUs). A cohort from three French University Hospitals was analysed in ICUs between 15th of March and the 15th of April 2020.

Machine learning is the key to diagnose COVID-19: a proof-of-concept study.

The reverse transcription-polymerase chain reaction (RT-PCR) assay is the accepted standard for coronavirus disease 2019 (COVID-19) diagnosis. As any test, RT-PCR provides false negative results that can be rectified by clinicians by confronting clinical, biological and imaging data. The combination of RT-PCR and chest-CT could improve diagnosis performance, but this would requires considerable resources for its rapid use in all patients with suspected COVID-19.

Prevention of hypothermia in trauma victims - the HYPOTRAUM 2 study.

Introduction: Hypothermia is common in trauma patients. It contributes to increasing mortality rate. Hypothermia is multifactorial, favoured by exposure to cold, severity of the patient's state and interventions such as infusion of fluids at room temperature.

Nitrous oxide/oxygen plus acetaminophen versus morphine in ST elevation myocardial infarction: open-label, cluster-randomized, non-inferiority study.

Background: Studies have shown disparate results on the consequences of morphine use in ST-segment elevation myocardial infarction (STEMI). No study has evaluated alternative treatments that could be at least non-inferior to morphine without its potentially damaging consequences for myocardial function and platelet reactivity. The aim of this study was to evaluate whether nitrous oxide/oxygen plus intravenous acetaminophen (NOO-A) is non-inferior to morphine to control chest pain in STEMI patients.

Patient care pathways in acute heart failure and their impact on in-hospital mortality, a French national prospective survey.

Background: Our purpose was to describe the care pathway of patients hospitalized for acute heart failure (AHF) and investigate whether a management involving a cardiology department had an impact on in-hospital mortality.

Methods: Between June 2014 and October 2018, we included patients hospitalized for AHF in 24 French hospitals. Characteristics of the episode, patient's care pathway and outcomes were recorded on a specific assessment tool.

Assessment of procedural pain in French emergency departments: a multi-site, non-interventional, transverse study in patients with minor trauma injury.

: To determine the mean number of procedural painful episodes per patient, and to retrieve information regarding diagnosis, therapeutic procedures and analgesic management, in patients visiting Emergency Departments (EDs) for minor trauma. : This observational, non-interventional, multicenter study in adult patients was performed in 35 French EDs. All patients entering the EDs for minor trauma on a specified day between noon and 10 pm were registered; consenting patients were included in the study.

Impact of acute infarct-related artery patency before percutaneous coronary intervention on 30-day outcomes in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention in the EUROMAX trial.

Aims: Early infarct-related artery patency has been associated with improved outcomes in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention. However, it is unknown whether this relationship persists in contemporary practice with pre-hospital initiation of treatment, use of novel P2Y inhibitors and frequent use of drug-eluting stents. The purpose of the study was to determine the impact of early infarct-related artery patency on outcomes in the contemporary EUROMAX trial.

One-Year Mortality for Bivalirudin vs Heparins Plus Optional Glycoprotein IIb/IIIa Inhibitor Treatment Started in the Ambulance for ST-Segment Elevation Myocardial Infarction: A Secondary Analysis of the EUROMAX Randomized Clinical Trial.

Importance: Uncertainty exists regarding potential survival benefits of bivalirudin compared with heparin with routine or optional use of glycoprotein IIb/IIIa inhibitors (GPIs) in patients with ST-segment elevation myocardial infarction (STEMI). Few data are available regarding long-term mortality in the context of contemporary practice with frequent use of radial access and novel platelet adenosine diphosphate P2Y12 receptor inhibitors.

Objective: To assess the effect of bivalirudin monotherapy compared with unfractionated or low-molecular-weight heparin plus optional GPIs on 1-year mortality.

Frequency and prognostic significance of access site and non-access site bleeding and impact of choice of antithrombin therapy in patients undergoing primary percutaneous coronary intervention. The EUROMAX trial.

Background: The overall impact of post percutaneous coronary intervention (PCI) bleeding on long term prognosis after acute coronary syndromes (ACS) has been established, but it may differ between access and non-access related bleeding events. The impact of antithrombin choice on bleeding may also differ according to the origin of the bleed. We sought to determine the origin of bleeding relative to the access site, its prognostic significance and the respective impact of antithrombin therapy in the EUROMAX trial.

Early invasive strategy in high-risk acute coronary syndrome without ST-segment elevation. The Sisca randomized trial.

Background: The optimal therapeutic strategy for patients with high-risk acute coronary syndrome without ST-segment elevation (NSTE-ACS) remains unclear.

Objective: Our aim was to compare the effectiveness of an early invasive strategy and a delayed invasive strategy in the management of high-risk NSTE-ACS patients.

Methods: This randomized clinical trial in a primarily pre-hospital setting enrolled patients with chest pain, electrocardiographic criteria for an NSTE-ACS, and at least one criterion of severity (ESC criterion or TIMI score >5).

ST-segment-elevation myocardial infarction patients randomized to a pharmaco-invasive strategy or primary percutaneous coronary intervention: Strategic Reperfusion Early After Myocardial Infarction (STREAM) 1-year mortality follow-up.

Background: In the Strategic Reperfusion Early After Myocardial Infarction (STREAM) trial, a pharmaco-invasive (PI) strategy was compared with primary percutaneous coronary intervention (pPCI) in ST-segment-elevation myocardial infarction patients presenting within 3 hours after symptom onset but unable to undergo pPCI within 1 hour. At 30 days, the PI approach was associated with a nominally but nonstatistically significant lower incidence of the composite primary end point of death, shock, congestive heart failure, and reinfarction when compared with pPCI. The aim of the present study was to determine the effect of these strategies on 1-year mortality.

Bivalirudin started during emergency transport for primary PCI.

Background: Bivalirudin, as compared with heparin and glycoprotein IIb/IIIa inhibitors, has been shown to reduce rates of bleeding and death in patients undergoing primary percutaneous coronary intervention (PCI). Whether these benefits persist in contemporary practice characterized by prehospital initiation of treatment, optional use of glycoprotein IIb/IIIa inhibitors and novel P2Y12 inhibitors, and radial-artery PCI access use is unknown.

Methods: We randomly assigned 2218 patients with ST-segment elevation myocardial infarction (STEMI) who were being transported for primary PCI to receive either bivalirudin or unfractionated or low-molecular-weight heparin with optional glycoprotein IIb/IIIa inhibitors (control group).

Comparison of two doses of ketoprofen to treat pain: a double-blind, randomized, noninferiority trial.

The aim of our study was to compare the efficacy and safety of two doses of ketoprofen (200 mg vs. 300 mg/day) in ambulatory emergency patients with pain related to traumatic and nontraumatic bone and joint diseases. We tested the hypothesis that the efficacy of the lower dose was not lower than that of the higher dose in a double-blind, randomized, noninferiority trial.

A simple nomogram for early prediction of myocardial reperfusion after pre-hospital thrombolysis.

Aims: To discriminate early ST-segment elevation myocardial infarction (STEMI) presenters at a high probability of successful pre-hospital thrombolysis (PHT) using a simple nomogram based on independent predictors of complete ST resolution.

Methods And Results: OPTIMAL was an observational, prospective study undertaken at 79 medical centres in France in patients with STEMI undergoing pre-hospital thrombolysis (PHT) within six hours of symptom onset and coronary angiography within six hours of thrombolysis. The baseline and pre-coronary angiography ECGs of 800 patients were analysed.

Prehospital fibrinolysis with dual antiplatelet therapy in ST-elevation acute myocardial infarction: a substudy of the randomized double blind CLARITY-TIMI 28 trial.

Background: Fibrinolytic therapy for acute ST-elevation myocardial infarction (STEMI) is frequently limited by delays in administration and by incomplete reperfusion or reocclusion of the infarct-related artery. Intensified prehospital management of STEMI may shorten time to treatment and improve outcomes.

Methods: We carried out a prospective substudy in 11 ambulance systems in 216 of the 3,491 patients with STEMI who were enrolled in the CLARITY-TIMI 28 trial.
