RESUMO
Rationale: Management of first episodes of primary spontaneous pneumothorax remains the subject of debate. Objectives: To determine whether first-line simple aspiration is noninferior to first-line chest tube drainage for lung expansion in patients with complete primary spontaneous pneumothorax. Methods: We conducted a prospective, open-label, randomized noninferiority trial. Adults aged 18-50 years with complete primary spontaneous pneumothorax (total separation of the lung from the chest wall), recruited at 31 French hospitals from 2009 to 2015, received simple aspiration (n = 200) or chest tube drainage (n = 202) as first-line treatment. The primary outcome was pulmonary expansion 24 hours after the procedure. Secondary outcomes were tolerance of treatment, occurrence of adverse events, and recurrence of pneumothorax within 1 year. Substantial discordance in the numerical inputs used for trial planning and the actual trial rates of the primary outcome resulted in a reevaluation of the trial analysis plan. Measurement and Main Results: Treatment failure occurred in 29% in the aspiration group and 18% in the chest tube drainage group (difference in failure rate, 0.113; 95% confidence interval [CI], 0.026-0.200). The aspiration group experienced less pain overall (mean difference, -1.4; 95% CI, -1.89, -0.91), less pain limiting breathing (frequency difference, -0.18; 95% CI, -0.27, -0.09), and less kinking of the device (frequency difference, -0.05; 95% CI, -0.09, -0.01). Recurrence of pneumothorax was 20% in this group versus 27% in the drainage group (frequency difference, -0.07; 95% CI, -0.16, +0.02). Conclusions: First-line management of complete primary spontaneous pneumothorax with simple aspiration had a higher failure rate than chest tube drainage but was better tolerated with fewer adverse events.

Research in prehospital and in-hospital emergency medicine is essential to the development of this discipline. By calling certain practices into question (thrombolysis for minor strokes, use of coagulation factors for patients with severe polytrauma), providing access to new technologies (video-laryngoscopy, POCT troponins in pre-hospital care) or questioning new practices (double defibrillation, pulmonary US in pneumonia), research enables emergency physicians to adapt their day-to-day practice.
La recherche en médecine d'urgence, tant sur le plan préhospitalier qu'hospitalier, est nécessaire et même indispensable à la fois au développement de cette discipline, mais également à la reconnaissance de ses spécificités. Par la remise en question de certaines pratiques (thrombolyse pour les AVC mineurs, utilisation de facteurs de la coagulation pour le polytraumatisé sévère), l'accès à de nouvelles technologies (vidéo-laryngoscopie, troponines POCT en préhospitalier) ou le questionnement sur de nouvelles pratiques (double défibrillation, US pulmonaire dans la pneumonie), la recherche permet aux urgentistes d'adapter leur pratique quotidienne à l'état de l'art.

BACKGROUND: Noise levels are monitored in call centres. A maximum of 52 to 55 dB(A) is recommended in order to prevent adverse events. We aimed at assessing the noise level and the impact of a visual noise indicator on the ambient noise level in a French Regional Emergency Medical Dispatch Centre (EMDC). METHODS: We conducted an observational study in the EMDC of the SAMU25 (University Hospital of Besancon). We measured the noise level using a SoundEarII® noise indicator (Dräger Medical SAS, France). The measurement took place in two phases on three consecutive days from 00:00 to 11:59 PM. At baseline, phase 1, the device recorded the average ambient noise for each minute without visual indication. Secondly, phase 2 included a sensor mounted with a light that would turn on green if noise was below 65 dB(A), orange if noise ever exceeded 65 and red if it exceeded 75 dB(A). RESULTS: In the presence of the visual noise indicator, the LAeq was significantly lower than in the absence of visual noise indicator (a mean difference of - 4.19 dB; P < 10-3). It was higher than 55 dB(A) in 84.9 and 43.9% of the time in phases 1 and 2, respectively. CONCLUSIONS: The noise levels were frequently higher than the standards, and sometimes close to recommended limits, requiring preventive measures. The noise indicator had a positive effect on the ambient noise level. This work will allow the implementation of effective prevention solutions and, based on future assessments, could improve operators' well-being and better care for patient.

Importance: Clinical 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. Objective: To 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 Participants: Stepped-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. Interventions: A 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 Measures: The 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. Results: Among 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 Relevance: Among 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: NCT03683212.

Importance: The safety of the pulmonary embolism rule-out criteria (PERC), an 8-item block of clinical criteria aimed at ruling out pulmonary embolism (PE), has not been assessed in a randomized clinical trial. Objective: To prospectively validate the safety of a PERC-based strategy to rule out PE. Design, Setting, and Patients: A crossover cluster-randomized clinical noninferiority trial in 14 emergency departments in France. Patients with a low gestalt clinical probability of PE were included from August 2015 to September 2016, and followed up until December 2016. Interventions: Each center was randomized for the sequence of intervention periods. In the PERC period, the diagnosis of PE was excluded with no further testing if all 8 items of the PERC rule were negative. Main Outcomes and Measures: The primary end point was the occurrence of a thromboembolic event during the 3-month follow-up period that was not initially diagnosed. The noninferiority margin was set at 1.5%. Secondary end points included the rate of computed tomographic pulmonary angiography (CTPA), median length of stay in the emergency department, and rate of hospital admission. Results: Among 1916 patients who were cluster-randomized (mean age 44 years, 980 [51%] women), 962 were assigned to the PERC group and 954 were assigned to the control group. A total of 1749 patients completed the trial. A PE was diagnosed at initial presentation in 26 patients in the control group (2.7%) vs 14 (1.5%) in the PERC group (difference, 1.3% [95% CI, -0.1% to 2.7%]; P = .052). One PE (0.1%) was diagnosed during follow-up in the PERC group vs none in the control group (difference, 0.1% [95% CI, -∞ to 0.8%]). The proportion of patients undergoing CTPA in the PERC group vs control group was 13% vs 23% (difference, -10% [95% CI, -13% to -6%]; P < .001). In the PERC group, rates were significantly reduced for the median length of emergency department stay (mean reduction, 36 minutes [95% CI, 4 to 68]) and hospital admission (difference, 3.3% [95% CI, 0.1% to 6.6%]). Conclusions and Relevance: Among very low-risk patients with suspected PE, randomization to a PERC strategy vs conventional strategy did not result in an inferior rate of thromboembolic events over 3 months. These findings support the safety of PERC for very low-risk patients presenting to the emergency department. Trial Registration: clinicaltrials.gov Identifier: NCT02375919.

INTRODUCTION: Acute respiratory failure is a life-threatening condition frequently found in the emergency department. High-flow nasal oxygen (HFNO) is increasingly used in emergency departments for patients with hypoxaemic acute respiratory failure. However, despite the increasing number of studies, its potential advantages regarding the need for therapeutic escalation and mortality have not been precisely evaluated. Our objective is to compare conventional oxygen therapy to HFNO when they are initiated during the first hour following the patient's arrival at the emergency department, with the hypothesis that HFNO would reduce the need for ventilatory therapy escalation. METHODS AND ANALYSIS: This is a multicentric, prospective, open and randomised superiority study. 500 inpatients will be randomised (1:1) to receive conventional oxygen therapy or HNFO. The primary outcome is a failure in the oxygen therapy defined as the need for a therapeutic escalation within 4 hours after therapy initiation. ETHICS AND DISSEMINATION: The study has been submitted and approved by the Comité de Protection des Personnes Nord Ouest IV (20 October 2020). As required, a notification was sent to the Agence nationale de sécurité du médicament et des produits de santé (22 October 2020). The research results will be published in peer-reviewed publications and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT04607967.

INTRODUCTION: We prospectively investigated whether home treatment of pulmonary embolism (PE), is as effective and safe as the recommended early discharge management in terms of outcomes at 3 months. METHODS: We performed a post hoc analysis of prospectively and consecutively recorded data in acute PE patients from a tertiary care facility between January 2012 and November 2021. Home treatment was defined as discharge to home directly from the emergency department (ED) after <24 h stay. Early discharge was defined as in-hospital stay of ≥24 h and ≤48 h. Primary efficacy and safety outcomes were a composite of PE-related death or recurrent venous thrombo-embolism, and major bleeding, respectively. Outcomes between groups were compared using penalized multivariable models. RESULTS: In total, 181 patients (30.6 %) were included in the home treatment group and 463 (69.4 %) patients in the early discharge group. Median duration of ED stay was 8.1 h (IQR, 3.6-10.2 h) in the home treatment group, and median length of hospital stay was 36.4 h (IQR, 28.7-40.2) in the early discharge group. The adjusted rate of the primary efficacy outcome was 1.90 % (95 % CI, 0.16-15.2) vs 2.05 % (95 % CI, 0.24-10.1) for home treatment vs early discharge (hazard ratio (HR) 0.86 (95 % CI, 0.27-2.74). The adjusted rates of the primary safety outcome did not differ between groups at 3 months. CONCLUSIONS: In a non-randomized cohort of selected acute PE patients, home treatment provided comparable rates of adverse VTE and bleeding events to the recommended early discharge management, and appears to have similar clinical outcomes at 3 months.

BACKGROUND AND IMPORTANCE: Diagnosing acute heart failure (AHF) is difficult in elderly patients presenting with acute dyspnea to the emergency department. OBJECTIVES: To assess the diagnostic accuracy of NT-proBNP, high-sensitivity cardiac troponin-I (Hs-cTnI), soluble ST2 (ST2), galectin-3 and CD146 alone and in combination for diagnosing AHF in elderly patients presenting with acute dyspnea to the emergency department. DESIGN, SETTINGS AND PARTICIPANTS: This was a prospective, multicenter study performed between September 2016 and January 2020, including elderly patients presenting with acute dyspnea to the emergency department of 6 French hospitals. INTERVENTION: Measurement of NT-proBNP, hs-cTnI, ST2, galectin-3 and CD146. OUTCOME MEASURE AND ANALYSIS: The reference standard, AHF, was adjudicated by two independent physicians based on ED and hospitalization clinical, biological (excluding biomarkers), radiological and echocardiography data (performed by a cardiologist in the cardiology department specifically for this study). Three exploratory methods (two using a cross-sectional approach with logistic regression and counting all biomarker combinations, and one using a sequential approach with gray zone optimizations) were applied to create comprehensive combinations of the 5 biomarkers for measuring diagnostic accuracy. MAIN RESULTS: Two hundred thirty-eight patients (median age of 85 years, IQRâ =â 8) were analyzed, and 110 (46%) were diagnosed with AHF. The accuracies of NT-proBNP, CD146, hs-cTnI, galectin-3, and ST2 were 0.72 [95% confidence interval (CI) 0.66-0.77], 0.63 (95% CI 0.57-0.69), 0.59 (95% CI 0.53-0.65), 0.55 (95% CI 0.49-0.61) and 0.51 (95% CI 0.45-0.57), respectively. Regardless of the approach used or how the 5 biomarkers were combined, the best accuracy for diagnosing AHF (0.73, 95% CI 0.67-0.78) did not differ from that of NT-proBNP alone. CONCLUSION: In this study, NT-proBNP alone exhibited the best diagnostic accuracy for diagnosing AHF in elderly patients presenting with acute dyspnea to the emergency departments. None of the other biomarkers alone or combined improved the accuracy compared to NT-proBNP, which is the only biomarker to use in this setting.

INTRODUCTION: Primary spontaneous pneumothorax (PSP) is the presence of air in the pleural space, occurring in the absence of trauma and known lung disease. Standardized expert guidelines on PSP are needed due to the variety of diagnostic methods, therapeutic strategies and medical and surgical disciplines involved in its management. METHODS: Literature review, analysis of the literature according to the GRADE (Grading of Recommendation, Assessment, Development and Evaluation) methodology; proposals for guidelines rated by experts, patients and organizers to reach a consensus. Only expert opinions with strong agreement were selected. RESULTS: A large PSP is defined as presence of a visible rim along the entire axillary line between the lung margin and the chest wall and ≥ 2 cm at the hilum level on frontal chest X-ray. The therapeutic strategy depends on the clinical presentation: emergency needle aspiration for tension PSP; in the absence of signs of severity: conservative management (small PSP), needle aspiration or chest tube drainage (large PSP). Outpatient treatment is possible if a dedicated outpatient care system is previously organized. Indications, surgical procedures and perioperative analgesia are detailed. Associated measures, including smoking cessation, are described. CONCLUSION: These guidelines are a step towards PSP treatment and follow-up strategy optimization in France.

INTRODUCTION: Prothrombin Complex Concentrate (PCC) is a key treatment in the management of bleeding related to Vitamin K antagonists (VKA). This study aimed to evaluate prospectively PCC use in patients with VKA-related bleeding in view of the French guidelines published in 2008. METHODS: All consecutive patients with VKA-related bleeding treated with a 4-factor PCC (Octaplex®) were selected in 33 French hospitals. Collected data included demographics, site and severity of bleeding, modalities of PCC administration, International Normalized Ratio (INR) values before and after PCC administration, outcomes and survival rate 15 days after infusion. RESULTS: Of 825 patients who received PCC between August 2008 and December 2010, 646 had severe bleeding. The main haemorrhage sites were intracranial (43.7%) and abdominal (24.3%). Mean INR before PCC was 4.4 ± 1.9; INR was unavailable in 12.5% of patients. The proportions of patients who received a PCC dose according to guidelines were 15.8% in patients with initial INR 2-2.5, 41.5% in patients with INR 2.5-3, 40.8% in patients with INR 3-3.5, 26.9% in patients with INR > 3.5, and 63.5% of patients with unknown INR. Vitamin K was administered in 84.7% of patients. The infused dose of PCC did not vary with initial INR; the mean dose was 25.3 ± 9.8 IU/Kg. Rates of controlled bleeding and target INR achievement were similar, regardless of whether or not patients were receiving PCC doses as per the guidelines. No differences in INR after PCC treatment were observed, regardless of whether or not vitamin K was administered. INR was first monitored after a mean time frame of 4.5 ± 5.6 hours post PCC. The overall survival rate at 15 days after PCC infusion was 75.4% (65.1% in patients with intracranial haemorrhage). A better prognosis was observed in patients reaching the target INR. CONCLUSIONS: Severe bleeding related to VKA needs to be better managed, particularly regarding the PCC infused dose, INR monitoring and administration of vitamin K. A dose of 25 IU/kg PCC appears to be efficacious in achieving a target INR of 1.5. Further studies are required to assess whether adjusting PCC dose and/or better management of INR would improve outcomes.

INTRODUCTION: The benefits of transporting severely injured patients by helicopter remain controversial. This study aimed to analyze the impact on mortality of helicopter compared to ground transport directly from the scene to a University hospital trauma center. METHODS: The French Intensive Care Research for Severe Trauma cohort study enrolled 2,703 patients with severe blunt trauma requiring admission to University hospital intensive care units within 72 hours. Pre-hospital and hospital clinical data, including the mode of transport, (helicopter (HMICU) versus ground (GMICU), both with medical teams), were recorded. The analysis was restricted to patients admitted directly from the scene to a University hospital trauma center. The main endpoint was mortality until ICU discharge. RESULTS: Of the 1,958 patients analyzed, 74% were transported by GMICU, 26% by HMICU. Median injury severity score (ISS) was 26 (interquartile range (IQR) 19 to 34) for HMICU patients and 25 (IQR 18 to 34) for GMICU patients. Compared to GMICU, HMICU patients had a higher median time frame before hospital admission and were more intensively treated in the pre-hospital phase. Crude mortality until hospital discharge was the same regardless of pre-hospital mode of transport. After adjustment for initial status, the risk of death was significantly lower (odds ratio (OR): 0.68, 95% confidence interval (CI) 0.47 to 0.98, P = 0.035) for HMICU compared with GMICU. This result did not change after further adjustment for ISS and overall surgical procedures. CONCLUSIONS: This study suggests a beneficial impact of helicopter transport on mortality in severe blunt trauma. Whether this association could be due to better management in the pre-hospital phase needs to be more thoroughly assessed.

OBJECTIVES: Emergency departments (EDs) were on the front line for the diagnostic workup of patients with COVID-19-like symptoms during the first wave. Chest imaging was the key to rapidly identifying COVID-19 before administering RT-PCR, which was time-consuming. The objective of our study was to compare the costs and organizational benefits of triage strategies in ED during the first wave of the COVID-19 pandemic. METHODS: We conducted a retrospective study in five EDs in France, involving 3712 consecutive patients consulting with COVID-like symptoms between 9 March 2020 and 8 April 2020, to assess the cost effectiveness of imaging strategies (chest radiography, chest computed tomography (CT) scan in the presence of respiratory symptoms, systematic ultra-low-dose (ULD) chest CT, and no systematic imaging) on ED length of stay (LOS) in the ED and on hospital costs. The incremental cost-effectiveness ratio was calculated as the difference in costs divided by the difference in LOS. RESULTS: Compared with chest radiography, workup with systematic ULD chest CT was the more cost-effective strategy (average LOS of 6.89 hours; average cost of 3646), allowing for an almost 4-hour decrease in LOS in the ED at a cost increase of 98 per patient. Chest radiography (extendedly dominated) and RT-PCR with no systematic imaging were the least effective strategies, with an average LOS of 10.8 hours. The strategy of chest CT in the presence of respiratory symptoms was more effective than the systematic ULD chest CT strategy, with the former providing a gain of 37 minutes at an extra cost of 718. DISCUSSION: Systematic ULD chest CT for patients with COVID-like symptoms in the ED is a cost-effective strategy and should be considered to improve the management of patients in the ED during the pandemic, given the need to triage patients.

A relationship between the occurrence of spontaneous pneumothorax (SP) and meteorological factors has been observed but with contradictory results. The objectives of this systematic review was to synthesis the current body of evidence to the relationships between the occurrence of SP and environmental determinants such as meteorological factors and air pollutants. We conducted a systematic search of MEDLINE, Scopus, Cochrane Library and gray literature from inception up to 31st December 2020, to find published scientific research articles based on the following eligibility criteria: original studies and population-based articles describing the relationship between meteorological factors or air pollutants and the occurrence of SP. For the meta-analysis, studies involving a quantitative analysis of the exposure variable (atmospheric pressure, temperature, humidity and wind speed) and the impact of the occurrence of SP with comparable methodology were selected. General characteristics and methodological information for each study were assessed. The quality was evaluated according to the Newcastle-Ottawa Scale. Fourty four and 13 studies were respectively included in the qualitative and quantitative analyses. The variability of the study design with moderate quality and the different measurements of the exposure variables highlight the contrasting results. The results of the meta-analyses are in favor of a higher temperature observed in the day with SP than in the days without SP (maximum: MD 0.25 (-0.08, 0.58) p = 0.14; I2 = 26%, p = 0.21; mean: MD 0.22 (-0.15, 0.59) p = 0.24; I2 = 45%, p = 0.07). The small number of studies focused on air pollution did not allow us to conclude to determine the potential impact of exposure to air pollutants on the occurrence of SP. Meteorological conditions seem to be related to SP occurrence, especially increased temperature.

OBJECTIVES: To determine the efficacy of emergency medical center physicians' use of a protocol to guide their management of telephone consultations for fever and gastroenteritis. MATERIAL AND METHODS: Cluster randomized controlled trial. Participating centers were randomized to use the telephone protocol or provide usual telephone assistance. Six emergency centers in France included calls from patients needing advice on fever or gastroenteritis. Centers assigned to the protocol followed specific guidelines on managing the call and giving advice on treatment. Primary endpoints were the number of in-person visits and hospital admissions required within 15 days of the call. Secondary endpoints were patient satisfaction and costs. RESULTS: A total of 2498 calls were included. Use of the assigned protocol while attending 1234 calls was associated with a relative risk for hospitalization or an unscheduled in-person visit for care of 0.70 (95% CI, 0.58-0.85) versus usual practice. Ambulance use, admission to an intensive care unit, mortality, morbidity, and symptom improvement did not differ significantly between centers using the protocol and those following usual practice. Ninety percent of the patients were satisfied. The cost of care was 91 in centers applying the protocol and 150 in the other centers (P .01). CONCLUSION: Use of the protocol was associated with fewer unscheduled in-person visits for care and fewer hospital admissions. The protocol is safe and less costly than the centers' usual approaches to giving telephone advice.
OBJETIVO: Determinar la eficacia de un protocolo de asesoramiento médico telefónico formalizado (AMTF), realizado por un médico para consultas, para fiebre o gastroenteritis en centros de comunicación médica de emergencia.

El grupo ATMF realizó recomendaciones protocolizadas sobre el manejo terapéutico. Se valoró el número de consultas presenciales o ingreso hospitalario durante los 15 días siguientes a la consulta. También se evaluó la satisfacción del paciente y el coste económico. RESULTADOS: Se incluyeron 2.498 llamadas. El grupo ATMF (n = 1.234) tuvo un riesgo relativo de 0,70 (CI 95% 0,58 a 0,85) de requerir un ingreso hospitalario o de realizar una consulta no programada durante el seguimiento. No hubo diferencias entre los dos grupos en cuanto al uso de ambulancia, el ingreso en cuidados intensivos, la mortalidad o morbilidad y la mejoría de los síntomas. La satisfacción de los pacientes fue del 90%. El coste total fue de 91 euros en el grupo de la ATMF y de 150 euros en el grupo de atención habitual (p 0,01). CONCLUSIONES: El grupo ATMF se asoció con una disminución de las consultas presenciales no programadas o del ingreso en el hospital. Este procedimiento es seguro y comporta un menor coste que la atención que se realiza habitualmente en la actualidad.

INTRODUCTION: Mechanical thrombectomy (MT) increases functional independence in patients with acute ischaemic stroke with anterior circulation large vessel occlusion (LVO), and the probability to achieve functional independence decreases by 20% for each 1-hour delay to reperfusion. Therefore, we aim to investigate whether direct angiosuite transfer (DAT) is superior to standard imaging/emergency department-based management in achieving 90-day functional independence in patients presenting with an acute severe neurological deficit likely due to LVO and requiring emergent treatment with MT. METHODS AND ANALYSIS: DIRECT ANGIO (Effect of DIRECT transfer to ANGIOsuite on functional outcome in patient with severe acute stroke treated with thrombectomy: the randomised DIRECT ANGIO Trial) trial is an investigator-initiated, multicentre, prospective, randomised, open-label, blinded endpoint (PROBE) study. Eligibility requires a patient ≤75 years, pre-stroke modified Rankin Scale (mRS) 0-2, presenting an acute severe neurological deficit and admitted within 5 hours of symptoms onset in an endovascular-capable centre. A total of 208 patients are randomly allocated in a 1:1 ratio to DAT or standard management. The primary outcome is the rate of patients achieving a functional independence, assessed as mRS 0-2 at 90 days. Secondary endpoints include patients presenting confirmed LVO, patients eligible to intravenous thrombolysis alone, patients with intracerebral haemorrhage and stroke-mimics, intrahospital time metrics, early neurological improvement (reduction in National Institutes of Health Stroke Scale by ≥8 points or reaching 0-1 at 24 hours) and mRS overall distribution at 90 days and 12 months. Safety outcomes are death and intracerebral haemorrhage transformation. Medico-economics analyses include health-related quality of life and cost utility assessment. ETHICS AND DISSEMINATION: The DIRECT ANGIO trial was approved by the ethics committee of Ile de France 1. Study began in April 2020. Results will be published in an international peer-reviewed medical journal. TRIAL REGISTRATION NUMBER: NCT03969511.

INTRODUCTION: This study was conducted to provide Intensive Care Units and Emergency Departments with a set of practical procedures (check-lists) for managing critically-ill adult patients in order to avoid complications during intra-hospital transport (IHT). METHODS: Digital research was carried out via the MEDLINE, EMBASE, CINAHL and HEALTHSTAR databases using the following key words: transferring, transport, intrahospital or intra-hospital, and critically ill patient. The reference bibliographies of each of the selected articles between 1998 and 2009 were also studied. RESULTS: This review focuses on the analysis and overcoming of IHT-related risks, the associated adverse events, and their nature and incidence. The suggested preventive measures are also reviewed. A check-list for quick execution of IHT is then put forward and justified. CONCLUSIONS: Despite improvements in IHT practices, significant risks are still involved. Basic training, good clinical sense and a risk-benefit analysis are currently the only deciding factors. A critically ill patient, prepared and accompanied by an inexperienced team, is a risky combination. The development of adapted equipment and the widespread use of check-lists and proper training programmes would increase the safety of IHT and reduce the risks in the long-term. Further investigation is required in order to evaluate the protective role of such preventive measures.
