Impact of an enhanced focused cardiac ultrasound on treatment changes in a population of internal medicine patients.

BACKGROUND: Hospitalized patients with acute shortness of breath (SOB) could benefit from an enhanced focused cardiac ultrasound (eFoCUS) with Doppler measurements to reassess treatment and diagnosis. METHODS: This was a retrospective observational study performed in a medical ward. Included patients were those hospitalized for acute SOB. The objectives were to assess therapeutic and diagnosis changes associated with eFoCUS. The primary endpoint of the analysis was a composite of introduction or discontinuation of diuretics, antibiotics or anticoagulation following eFoCUS. RESULTS: Between January 2018 and July 2021, 119 patients were included, 67 women and 52 men, mean age 84 ± 11 years old. The eFoCUS was performed within a median time of 55 h (1st-3rd IQ: 21-107) following hospital admission. Overall, eFoCUS was associated with a change in diagnostic in 40 patients (34% [CI 95%: 25%-43%], p < 10-4 ) and a change in treatment in 53 patients (45% [CI 95%: 35%-54%], p < 10-4 ). Diuretics were prescribed in 94 patients before eFoCUS and in 56 after (p = 10-4 ), antibiotics in 34 before and 27 after and anticoagulation in 30 before and 40 after. CONCLUSION: eFoCUS was associated with both therapeutic and diagnostic changes in patients with SOB. Such results should be confirmed in multicentric prospective studies.

Is a Positive Prehospital FAST Associated with Severe Bleeding? A Multicenter Retrospective Study.

INTRODUCTION: Severe hemorrhage is the leading cause of early preventable death in severe trauma patients. Delayed diagnosis is a poor prognostic factor, and severe hemorrhage prediction is essential. The aim of our study was to investigate if there was an association between the detection of peritoneal or pleural fluid on prehospital sonography for trauma and posttraumatic severe hemorrhage. METHODS: We retrospectively studied data from records of thoracic or abdominal trauma patients managed in mobile intensive care units from January 2017 to December 2021 in four centers in France. Severe hemorrhage was defined as a condition necessitating transfusion of at least four packed red blood cells or surgical intervention/radioembolization for hemostasis within the first 24 h. Using a multivariate analysis, we investigated the predictive performance of focused assessment with sonography for trauma (FAST) alone or in combination with the five Red Flags criteria validated by Hamada et al. RESULTS: Among the 527 patients analyzed, 371 (71%) were men, the mean age was 41 ± 19 years, and the Injury Severity Score was 11 (Interquartile range = [5; 22]). Seventy-three (14%) patients had severe hemorrhage - of whom 28 (38%) had a positive FAST, compared to 61 (13%) without severe hemorrhage (p < 0.01). For severe hemorrhage prediction, FAST had a sensitivity of 38% (95%CI = [27%; 50%]) and a specificity of 87% (95%CI = [83%; 90%]) (AUC = 0.62, 95%CI = [0.57; 0.68]). The comparison of the other outcomes between positive and negative FAST was: hemostatic procedure, 22 (25%) vs 28 (6%), p < 0.01; intensive care unit admission 71 (80%) vs 190 (43%), p < 0.01; mean length of hospital stay 11 [4; 27] vs 4 [0; 14] days, p = 0.02; 30-day mortality 13 (15%) vs 22 (5%), p < 0.01. CONCLUSION: A positive FAST performed in the prehospital setting is associated with severe hemorrhage and all prognostic criteria we studied.

[Reception of a patient suspected of having a psychiatric condition in an emergency department]. / Accueil d'un patient suspect d'une pathologie psychiatrique en structure des urgences.

Many emergency patients have pre-existing psychiatric conditions. They may also present a symptomatology likely to evoke this type of psychiatric pathology. The way in which these patients are received and managed is of prime importance, as it determines the subsequent treatment. It is therefore essential that the emergency services organise a specific pathway for these patients.

[The elderly with a psychiatric prognosis in the emergency room]. / Le sujet âgé à présentation psychiatrique aux urgences.

In the emergency department, the diagnosis of an acute psychiatric condition in an elderly patient should only be made after rigorous clinical and paraclinical examinations to rule out any somatic pathology. In addition, the management and treatment of acute agitation must be adapted.

Maximum Value of End-Tidal Carbon Dioxide Concentrations during Resuscitation as an Indicator of Return of Spontaneous Circulation in out-of-Hospital Cardiac Arrest.

Background: The end-tidal carbon dioxide (ETCO2) concentration during resuscitation (CPR) of an out-of-hospital cardiac arrest (OHCA) has an increasingly well-known prognostic value. Nevertheless, few studies have investigated its maximum value in different etiologies. Methods: It was a retrospective, observational, multicentre study from the French OHCA Registry. All adult OHCA with a known maximum value of ETCO2 during CPR were included. The primary end-point was to determine the area under the receiver operating characteristic curve (AUROC) of the maximum value of ETCO2 during resuscitation for the return of spontaneous circulation (ROSC). Results: Of the 53,048 eligible subjects from 2011 to 2018, ETCO2 was known in 32,249 subjects (61%). Among them, there were 9.2% of traumatic OHCA, 37.7% of suspected cardiac etiology and 16.4% of suspected respiratory etiology. The AUROC of maximum value of ETCO2 during CPR to achieve ROSC was 0.887 95CI [0.875-0.898] in traumatic OHCA, 0.772 95CI [0.765-0.780] in suspected cardiac etiology and 0.802 95CI [0.791-0.812] in suspected respiratory etiology. The threshold with no survivors at d-30 was <10 mmHg for traumatic etiologies and <6 mmHg for suspected cardiac and respiratory causes. The probability of ROSC increased with the value of ETCO2 in the 3 etiologies studied. Conclusions: The maximum value of ETCO2 during OHCA resuscitation was strongly associated with ROSC, especially in the case of a traumatic cause. This suggests that a single elevated ETCO2 value, regardless of time, could help to predict the outcome.

Recognition and treatment of severe sepsis in the emergency department: retrospective study in two French teaching hospitals.

BACKGROUND: Sepsis management in the Emergency Department remains a daily challenge. The Surviving Sepsis Campaign (SSC) has released three-hour bundle. The implementation of these bundles in European Emergency Departments remains poorly described. The main objective was to assess the compliance with the Severe Sepsis Campaign 3-h bundle (blood culture, lactate dosage, first dose of antibiotics and 30 ml/kg fluid challenge). Secondary objectives were the analysis of the delay of severe sepsis recognition and description of the population. METHODS: In accordance with STROBE statement, we performed a retrospective study in two French University Hospital Emergency Departments from February to August 2015. Patients admitted during the study period were screened using the electronic files of the hospital databases. Patient's files were reviewed and included in the study if they met severe sepsis criteria. Demographics, comorbities, treatments were recorded. Delays from admission to severe sepsis diagnosis, fluid loading onset and antibiotics administration were calculated. RESULTS: One hundred thirty patients were included (76 men, mean age 71 ± 14 years). Blood culture, lactate dosage, antibiotics and 30 ml/kg fluid loading were performed within 3 hours in % [95% confidence interval] 100% [96-100%], 62% [54-70%], 49% [41-58%] and 19% [13-27%], respectively. 25 patients out of 130 (19% [13-27%]) fulfilled each criteria of the 3-h bundle. The mean fluid loading volume was 18 ± 11 ml/kg. Mean delay between presentation and severe sepsis diagnosis was 200 ± 263 min, from diagnosis to fluid challenge and first antibiotic dose, 10 ± 27 min and 20 ± 55 min, respectively. CONCLUSION: Compliance with SSC 3-h bundle and delay between admission and sepsis recognition have to be improved. If confirmed by other studies, an improvement program might be deployed.

Effects of the delivery of physiotherapy on the treatment course of elderly fallers presenting to the emergency department: Protocol for a randomized clinical trial.

The use of physiotherapy (PT) in the hospital emergency department (ED) has shown positive results including improvements in patient waiting time, treatment initiation, discharge type, patient outcomes, safety and acceptability of the intervention by medical staffs. These findings originate from studies that primarily focus on musculoskeletal and orthopaedic conditions. Despite a significant number of people visiting the ED, there is a shortage of literature evaluating PT in the ED for elderly populations. The objective of this study is the evaluate the effect of delivering PT in the ED (versus no delivery) in patients aged 75 and over with 'falls' complaints. The main objective is the evaluate the effect on the discharge disposition (discharge home, hospitalization). Secondarily, we will evaluate the effect delivering PT on patient-length of stay, the number of falls at 7 days after admission to the ED, changes between the initial and final medical decision regarding patient orientation, and medical staff satisfaction. This study will follow a prospective longitudinal design involving participants aged 75 years and over. We plan to recruit a total n = 336 patients admitted to the ED with a 'fall' chief complaint. After consent, participants will be randomized into either the 'PT-group' (receiving a prescription and execution of PT within the ED), or to the 'no-PT group' (no delivery of PT within the ED). The PT intervention will involve a standardized assessment of motor capacities using validated clinical examinations, and the delivery of rehabilitative exercises based on individual needs. Outcomes will be recorded from the patient's medical record, and a phone call at 7 days. A questionnaire will be sent to medical staff. The results of this study will help to determine whether PT might be beneficial for the management of this increasing proportion of individuals who come to the ED.

Impact of Different Training Methods on Daily Use of Point-of-Care Ultrasound: Survey on 515 Physicians.

ABSTRACT: Point-of-care ultrasound (POCUS) curriculum varies among countries. However, the length of training required for physicians is still under debate. We investigated the impact of different training methods: short hands-on courses (STS), long academic training sessions (LTS), or both (mixed training [MTS]), for POCUS daily use and self-reported confidence overall and specific to specific clinical situations. This was a descriptive study conducted over a 3-month period through a Web-based survey designed to assess the influence of different methods of POCUS training among physicians and residents on their daily practice. The survey was sent to 1212 emergency physicians with prior POCUS training; 515 answers (42%) could be analyzed. Participants in the STS group performed POCUS less frequently than physicians in the LTS or MTS group. Daily use in the STS group was 51% versus 82% in the LTS group and 83% in the MTS group ( P < 0.01). The overall self-reported confidence in POCUS was lower in the STS group ( P < 0.01) in all studied clinical situations. There was no significant difference between LTS and MTS groups ( P > 0.05). Method of POCUS training significantly influenced POCUS daily use. Physicians who underwent long training sessions used POCUS more frequently in their routine practice and were significantly more confident in their ability to perform and interpret a POCUS examination.

Impact of emergency physician performed ultrasound in the evaluation of adult patients with acute abdominal pain: a prospective randomized bicentric trial.

BACKGROUND: Abdominal pain is common in patients visiting the emergency department (ED). The aim of this study was to assess the diagnostic contribution of point-of-care ultrasound (POCUS) in patients presenting to the ED with acute abdominal pain. METHODS: We designed an interventional randomized, controlled, open label, parallel-group, trial in two French EDs. We included adult patients presenting to the ED with acute abdominal pain. Exclusion criteria were a documented end-of-life, an immediate need of life-support therapy and pregnant or breast-feeding women. Patients were randomized in the experimental group (i.e., workup including POCUS) or control group (usual care). The primary objective of the study was to assess the added value of POCUS on diagnostic pathway in the ED, according to the diagnostic established a posteriori by an adjudication committee. The primary endpoint was the proportion of exact preliminary diagnosis between the 2 groups. The preliminary diagnosis made after clinical examination and biological results with POCUS (intervention arm) or without POCUS (usual care) was considered exact if it was similar to the adjudication committee diagnosis. RESULTS: Between June 2021 11th and June 2022 23th, 256 patients were randomized, but five were not included in the primary analysis, leaving 125 patients in the POCUS group and 126 patients in the usual care group (130 women and 121 men, median [Q1-Q3] age: 42 [30;57]). There was no difference for exact diagnosis between the two groups (POCUS 70/125, 56% versus control 78/126 (62%), RD 1.23 [95% CI 0.74-2.04]). There was no difference in the accuracy for the diagnosis of non-specific abdominal pain nor number of biological or radiological exams. Diagnostic delays and length of stay in the ED were also similar. CONCLUSIONS: In this trial, systematic POCUS did not improve the rate of diagnostic accuracy in unselected patients presenting to the ED with acute abdominal pain. However, as it was a safe procedure, further research should focus on patients with suspected etiologies where POCUS is particularly useful. TRIAL REGISTRATION:  This trial was registered on ClinicalTrials.gov on 2022/07/20 ( https://clinicaltrials.gov/study/NCT04912206?id=NCT04912206&rank=1 ) (NCT04912206).

Results of an outpatient transient ischemic attack evaluation: a 90-day follow-up study.

BACKGROUND: Transient ischemic attack (TIA) is common and precedes 15% of strokes. TIA should be managed as a time-sensitive illness to prevent a subsequent stroke. However, management of TIA is heterogeneous, with little consensus about its optimal assessment. OBJECTIVE: The objective of this study was to determine the outcome of patients with TIA evaluated in the Emergency Department (ED) and managed as outpatients within a 90-day period after discharge. METHODS: All patients with symptoms of TIA admitted to the ED were eligible for inclusion. Patients were evaluated by an Emergency Physician who followed a decision algorithm used in the selection of patients for discharge. The main outcome variable was the occurrence of stroke during the 90 days after discharge from the ED. RESULTS: During a 1-year period, a total of 118 patients were evaluated for TIA in the ED, representing 1.4% of ED medical admissions: 56 (47.5%) were hospitalized and 62 (52.5%) were discharged and enrolled in the outpatient TIA management. Two (3.2%) of the discharged patients could not be contacted for follow-up. Among the patients managed as outpatients, one (1.7%) presented with an ischemic stroke and 3 (5%) experienced a subsequent TIA within a period of 90 days after discharge from the ED. The rate of stroke predicted from the ABCD2 score was 9.7% at 90 days. CONCLUSION: The results of our study suggest that outpatient management of TIA, as described in our institution's guidelines, may be a safe and effective strategy, but further confirmatory studies should be performed.

Predictive factors of successful telephone-assisted cardiopulmonary resuscitation.

BACKGROUND: Our emergency medical service developed a telephone (phone)-assisted cardiopulmonary resuscitation (PACPR) procedure. OBJECTIVES: To describe this procedure and study the factors modulating its implementation. METHODS: We conducted a single-center prospective study of telephone calls to our emergency medical communication center for cardiac arrest, for which PACPR was initiated. RESULTS: Thirty-eight patients were included in the study. In six cases, cardiopulmonary resuscitation (CPR) had been started before the call. When PACPR was initiated, CPR was performed until the rescue team arrived in 27 cases. One-third (n = 9) of the bystanders in these cases knew first-aid interventions, and all of these bystanders continued CPR until the rescue team arrived. The absence of a familial relationship between bystander and patient facilitated the continuation of CPR (100% vs. 37% with family ties, p = 0.01). CPR was continued more often if the bystander immediately agreed to PACPR than when he or she did not agree at first (88% vs. 45%, respectively, p = 0.01). When an obstacle to performing CPR was encountered, CPR was then performed in 57% of cases vs. 100% of cases with no obstacle (p = 0.003). These obstacles were associated with either the bystander (panic, apprehension, feelings of inadequacy, physical inability, indirect witness, tiredness) or the victim (morphotype, physical position). The presence of an obstacle, compared to no obstacle, associated with the bystander lowered the CPR performance rate (58% vs. 94%, respectively, p = 0.01). The presence of an obstacle, compared to no obstacle, associated with the victim also lowered CPR performance rate (50% vs. 85%, respectively, p = 0.04). CONCLUSION: Our study demonstrates the feasibility of PACPR. The results may lead to a better understanding of facilitating factors and obstacles to telephone-assisted CPR, with the goal of improving its implementation. Good command of communication tools, identification of an appropriate bystander, and appropriate victim positioning are three fundamental factors of success.

Noninvasive ventilation use in French out-of-hospital settings: a preliminary national survey.

OBJECTIVE: The objective of our study was to describe noninvasive ventilation (NIV) practices (pressure support ventilation and continuous positive airway pressure) in French out-of-hospital mobile intensive care units (SMUR) and their compliance with national consensus guidelines. METHOD: Online inquiry into practices of NIV among managers of French SMUR. Analyzed data include types of NIV devices and use of NIV. RESULTS: Upon 218 SMUR referenced within the SAMU de France database, 118 questionnaires (54%) were processed. Noninvasive ventilation equipment: 91% of the SMUR with at least one type of NIV device (continuous positive airway pressure only=82%; pressure support ventilation only=59%; both=50%) but frequently not with recommended devices. Use of NIV: for acute cardiogenic pulmonary edema, practices were compliant with recommendations in 80% of cases, although there was still room for improvement. For other pathologies, practices were very heterogeneous, not always properly assessed, and frequently not compliant with recommendations. CONCLUSION: To conclude, NIV use in the out-of-hospital setting in France seems to meet current recommendations for acute cardiogenic pulmonary edema but not for other pathologies. This could be improved by the use of written procedures, conduction of further studies, and promotion of compliance through education.

Base excess is an accurate predictor of elevated lactate in ED septic patients.

BACKGROUND: Prior studies showed that lactate is a useful marker in sepsis. However, lactate is often not routinely drawn or rapidly available in the emergency department (ED). OBJECTIVE: The study aimed to determine if base excess (BE), widely and rapidly available in the ED, could be used as a surrogate marker for elevated lactate in ED septic patients. METHODS: This was a prospective and observational cohort study. From March 2009 to March 2010, consecutive patients 18 years or older who presented to the ED with a suspected severe sepsis were enrolled in the study. Lactate and BE measurements were performed. We defined, a priori, a clinically significant lactate to be greater than 3 mmol/L and BE less than -4 mmol/L. RESULTS: A total of 224 patients were enrolled in the study. The average BE was -4.5 mmol/L (SD, 4.9) and the average lactate was 3.5 mmol/L (SD, 2.9). The sensitivity of a BE less than -4 mmol/L in predicting elevated lactate greater than 3 mmol/L was 91.1% (95% confidence interval, 85.5%-96.6%) and the specificity was 88.6% (95% confidence interval, 83.0%-94.2%). The area under the curve was 0.95. CONCLUSION: Base excess is an accurate marker for the prediction of elevated lactate in the ED. The measurement of BE, obtained in a few minutes in the ED, provides a secure and quick method, similar to the electrocardiogram at triage for patients with chest pain, to determine the patients with sepsis who need an early aggressive resuscitation.

Identification of potential organ donors of advanced age in EDs.

OBJECTIVE: In France and in Belgium, as in many countries, there is a shortage of organs for transplantation, which has led to strategies to recruit older potential donors who may die of stroke. METHODS: We conducted a post hoc analysis to identify potential organ donors with cardiac function among a population of dying patients in emergency departments. This population had been selected for a separate multicenter prospective observational study. We identified patients who died of a neurologic cause but had no clinical findings affecting their donor status. RESULTS: Of 2420 patients in the study, 407 died of a neurologic cause; and 233 of these were excluded because of clinical factors that made them ineligible as organ donors. The remaining 174 patients (7.2% of dying patients) could be considered potential organ donors. Their mean age was 75.2 ± 11 years. Sixty-eight (39%) were intubated, and 60 of these (34.5%) were mechanically ventilated. In addition, 94 patients (54%) died within 12 hours (median, 9.3 hours) after admission; and 13 (7%) died while receiving a maximum level of care. No diagnostic procedures were performed to assess brain death. CONCLUSION: A significant number of patients who die in emergency departments could be organ donors, including approximately 7% between 60 and 85 years of age with life-threatening neurologic diseases. However, this percentage may be reduced by family opposition. Emergency physicians should collaborate with intensive care units and local organ donation teams to optimize end-of-life care and maximize the number of potential donors.

Outcome of chest pain patients discharged from a French emergency department: a 60-day prospective study.

BACKGROUND: Chest pain (CP) is a common complaint among patients presenting to the emergency department (ED). Previous studies suggest that between 2% and 5% of ED patients who present with CP and are sent home develop an acute coronary syndrome within 30 days. In France, no prospective data are available concerning the outcome of CP patients discharged from the ED. OBJECTIVE: The objective of our study was to determine the rate of adverse cardiac events (ACE) within a period of 60 days after discharge from the ED. METHODS: From October 2007 to February 2008, consecutive patients aged 25 years or more who presented to the ED with CP were prospectively included. Patients discharged from the ED were contacted by phone at 60 days to determine their clinical course and the occurrence of an ACE. RESULTS: There were 322 CP patients enrolled, representing 3.9% of all medical admissions to the ED; 40.4% of these patients were hospitalized and 59.6% were discharged. Three patients (1.6%) could not be contacted for follow-up, leaving 189 patients eligible for the study. The rate of ACE was 3.7%: one ST-segment elevation myocardial infarction and six non-ST-segment elevation myocardial infarctions. Follow-up revealed that 39.1% of patients saw a cardiologist and that 14.2% were readmitted for CP. CONCLUSION: We found that CP is a frequent complaint in patients who present to our ED, and that a small proportion (3.7%) is mistakenly discharged and presents with an ACE during the 60-day follow-up period.

Palliative care for patients who died in emergency departments: analysis of a multicentre cross-sectional survey.

OBJECTIVES: A growing number of patients die each year in hospital emergency departments (EDs). Decisions to withhold or to withdraw life-support therapies occur in 80% of patients as described in a multicentre cross-sectional survey including 2420 patients. Palliative care has not been explored in patients dying in this setting. The aim of this study was to assess the incidence of palliative care and to describe this population. METHODS: The authors conducted a post-hoc analysis on a cohort of 2420 patients who died in 174 French and Belgian EDs. The authors identified patients who benefited from palliative care and described this population and the palliative care. RESULTS: Palliative therapies were administered to 1373 patients (56.7%). These therapies included administration of analgesics, sedation, mouth care, repositioning for comfort (as appropriate) and provision of emotional support to the patient and his/her relatives. These palliative measures were provided more frequently in the observation unit of the ED (n=908, 66.2%) than in an examination room (n=465, 33.8%). Median time interval between ED admission and death was longer in patients who received palliative care (n=1373) (median, 15 h; first quartile, 6 h; third quartile, 34 h) than in those who did not (n=1047) (median, 4 h; first quartile, 1 h; third quartile, 10 h) (p<10(-4)). CONCLUSIONS: Palliative care is administered to about half of the patients who die in EDs. This is insufficient as the majority of the patients who died in EDs actually died after a decision to withhold or withdraw life-support therapies. End-of-life management must be improved in EDs.

Impact of emergency physician-performed ultrasound for the evaluation of patients with acute abdominal pain, prospective randomized dual Centre study: study protocol for a diagnostic trial.

BACKGROUND: Abdominal pain is frequent in patients consulting in emergency departments. The aim of this study is to determine the diagnosis efficacy of point-of-care ultrasound (POCUS) in patients consulting in the ED for acute abdominal pain by comparing the rate of exact diagnostic between the two arms (with or without POCUS), according to the index diagnostic established by an adjudication committee. METHODS: It is a randomized, controlled, open and interventional study in two emergency departments. The included patients will be adults admitted for acute abdominal pain. Exclusion criteria will be a documented end-of-life, an immediate need of life-support therapy and pregnant or breast-feeding women. Patients will be randomized in intervention (POCUS) or control groups. POCUS will only be performed by trained physicians and will be added to the diagnosis procedure in the intervention group. In the control group, the diagnosis will be established after clinical examination and reception of biological analysis results. In the interventional group, the diagnosis will be established after a clinical exam, biological analysis reception and POCUS. An adjudication committee will review all data from case report forms and will determine the index diagnosis which will be used for the analysis. The primary endpoint will be the comparison of the rate of exact diagnostic between the two arms according to the adjudication committee diagnostic. Secondary endpoints will be the comparison between the two groups for diagnostic delay, duration of ED stay, diagnostic performances for non-specific abdominal pain and hospitalization rate. The primary endpoint will be compared between the two groups using a mixed model taking into account the recruiting centre. Delays will be compared by a mixed linear generalized model. Diagnostic performances will be estimated with their 95% confidence intervals. For a correct diagnostic rate of 57% in the control group and 74% in the intervention group with a 0.05 alpha risk and a 80% power, 244 patients will be required. DISCUSSION: POCUS diagnostic abilities have been mainly demonstrated in monocentric studies but the level of evidence of its diagnostic efficacy remains controversial in particular in Europe. The aim of this study is to address this question with a rigorous methodology. TRIAL REGISTRATION: ClinicalTrials.gov NCT04912206. Registered on June 3, 2021.

Guidelines for the choice of intravenous fluids for vascular filling in critically ill patients, 2021.

PURPOSE: To provide recommendations for the appropriate choice of fluid therapy for resuscitation of critically ill patients. DESIGN: A consensus committee of 24 experts from the French Society of Anaesthesia and Intensive Care Medicine (Société française d'anesthésie et de réanimation, SFAR) and the French Society of Emergency Medicine (Société française de médecine d'urgence, SFMU) was convened. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. The entire guideline elaboration process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide their assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasised. Some recommendations were left ungraded. METHODS: Four fields were defined: patients with sepsis or septic shock, patients with haemorrhagic shock, patients with acute brain failure, and patients during the peripartum period. For each field, the panel focused on two questions: (1) Does the use of colloids, as compared to crystalloids, reduce morbidity and mortality, and (2) Does the use of some specific crystalloids effectively reduce morbidity and mortality. Population, intervention, comparison, and outcomes (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. The analysis of the literature and the recommendations were then conducted according to the GRADE methodology. RESULTS: The SFAR/SFMU guideline panel provided nine statements on the appropriate choice of fluid therapy for resuscitation of critically ill patients. After two rounds of rating and various amendments, strong agreement was reached for 100% of the recommendations. Out of these recommendations, two have a high level of evidence (Grade 1 +/-), six have a moderate level of evidence (Grade 2 +/-), and one is based on expert opinion. Finally, no recommendation was formulated for two questions. CONCLUSIONS: Substantial agreement among experts has been obtained to provide a sizable number of recommendations aimed at optimising the choice of fluid therapy for resuscitation of critically ill patients.

Guidelines for the management of urgent obstetric situations in emergency medicine, 2022.

OBJECTIVE: To provide recommendations on the management of urgent obstetrical emergencies outside the maternity ward. DESIGN: A group of 24 experts from the French Society of Emergency Medicine (SFMU), the French Society of Anaesthesia and Intensive Care Medicine (SFAR) and the French College of Gynaecologists and Obstetricians (CNGOF) was convened. Potential conflicts of interest were formally declared at the outset of the guideline development process, which was conducted independently of industry funding. The authors followed the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method to assess the level of evidence in the literature. The potential drawbacks of strong recommendations in the presence of low-level evidence were highlighted. Some recommendations with an insufficient level of evidence were not graded. METHODS: Eight areas were defined: imminent delivery, postpartum haemorrhage (prevention and management), threat of premature delivery, hypertensive disorders in pregnancy, trauma, imaging, cardiopulmonary arrest, and emergency obstetric training. For each field, the expert panel formulated questions according to the PICO model (population, intervention, comparison, outcomes) and an extensive literature search was conducted. Analysis of the literature and formulation of recommendations were conducted according to the GRADE method. RESULTS: Fifteen recommendations on the management of obstetrical emergencies were issued by the SFMU/SFAR/CNGOF panel of experts, and 4 recommendations from formalised expert recommendations (RFE) established by the same societies were taken up to answer 4 PICO questions dealing with the pre-hospital context. After two rounds of voting and several amendments, strong agreement was reached for all the recommendations. For two questions (cardiopulmonary arrest and inter-hospital transfer), no recommendation could be made. CONCLUSIONS: There was significant agreement among the experts on strong recommendations to improve practice in the management of urgent obstetric complications in emergency medicine.

Contribution of lung ultrasound in diagnosis of community-acquired pneumonia in the emergency department: a prospective multicentre study.

Lung ultrasound (LUS) can help clinicians make a timely diagnosis of community-acquired pneumonia (CAP). OBJECTIVES: To assess if LUS can improve diagnosis and antibiotic initiation in emergency department (ED) patients with suspected CAP. DESIGN: A prospective observational study. SETTINGS: Four EDs. PARTICIPANTS: The study included 150 patients older than 18 years with a clinical suspicion of CAP, of which 2 were subsequently excluded (incorrect identification), leaving 148 patients (70 women and 78 men, average age 72±18 years). Exclusion criteria included a life-threatening condition with do-not-resuscitate-order or patient requiring immediate intensive care. INTERVENTIONS: After routine diagnostic procedure (clinical, radiological and laboratory tests), the attending emergency physician established a clinical CAP probability according to a four-level Likert scale (definite, probable, possible and excluded). An LUS was then performed, and another CAP probability was established based on the ultrasound result. An adjudication committee composed of three independent experts established the final CAP probability at hospital discharge. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary objective was to assess concordance rate of CAP diagnostic probabilities between routine diagnosis procedure or LUS and the final probability of the adjudication committee. Secondary objectives were to assess changes in CAP probability induced by LUS, and changes in antibiotic treatment initiation. RESULTS: Overall, 27% (95% CI 20 to 35) of the routine procedure CAP classifications and 77% (95% CI 71 to 84) of the LUS CAP classifications were concordant with the adjudication committee classifications. Cohen's kappa coefficients between routine diagnosis procedure and LUS, according to adjudication committee, were 0.07 (95% CI 0.04 to 0.11) and 0.61 (95% CI 0.55 to 0.66), respectively. The modified probabilities for the diagnosis of CAP after LUS resulted in changes in antibiotic prescriptions in 32% (95% CI 25 to 40) of the cases. CONCLUSION: In our study, LUS was a powerful tool to improve CAP diagnosis in the ED, reducing diagnostic uncertainty from 73% to 14%. TRIAL REGISTRATION NUMBER: NCT03411824.
