ABSTRACT
BACKGROUND: Burnout among emergency health care professionals is well-described, especially during the COVID-19 pandemic. Prevention interventions, such as mindfulness, focus on the management of stress. OBJECTIVE: To evaluate the effects of the FIRECARE program (a mindfulness intervention, supplemented by heart coherence training and positive psychology workshops) on burnout, secondary stress, compassion fatigue, and mindfulness among advanced life support ambulance staff of the Paris Fire Brigade. MATERIALS AND METHODS: We used a non-randomized, two-group quasi-experimental study design with a waitlist control and before-and-after measurements in each group. The intervention consisted of six, once-weekly, 2.5-h sessions that included individual daily meditation and cardiac coherence practice. The study compared intervention and waitlist control groups, and investigated baseline, post-program, and 3-month follow-up change on burnout (measuring using the ProQOL-5 scale) and mindfulness (measuring using the FMI scores). Baseline burnout (measured using the ProQOL-5) was evaluated and used in the analysis. RESULTS: Seventy-four 74 participants volunteered to participate; 66 were included in the final analysis. Of these, 60% were classified as suffering from moderate burnout, the 'burnout cluster'. A comparison of intervention and waitlist control groups found a decrease in the burnout score in the burnout cluster (p = 0.0003; partial eta squared = 0.18). However, while secondary stress fell among the burnout cluster, it was only for participants in the intervention group; scores increased for those in the waitlist group (p = 0.003; partial eta squared = 0.12). The pre-post-intervention analysis of both groups also showed that burnout fell in the burnout cluster (p = 0.006; partial eta squared = 0.11). At 3-month follow-up, the burnout score was significantly reduced in the intervention group (p = 0.02; partial eta squared = 0.07), and both the acceptance (p = 0.007) and mindfulness scores (p = 0.05; partial eta squared = 0.05) were increased in the baseline burnout cluster. CONCLUSION: FIRECARE may be a useful approach to preventing and reducing burnout among prehospital caregivers.

BACKGROUND: There exists a need for prognostic tools for the early identification of COVID-19 patients requiring intensive care unit (ICU) admission and mortality. Here we investigated the association between a clinical (initial prehospital shock index (SI)) and biological (initial prehospital lactatemia) tool and the ICU admission and 30-day mortality among COVID-19 patients cared for in the prehospital setting. METHODS: We retrospectively analysed COVID-19 patients initially cared for by a Paris Fire Brigade advanced (ALS) or basic life support (BLS) team in the prehospital setting between 2020, March 08th and 2020, May 30th. We assessed the association between prehospital SI and prehospital lactatemia and ICU admission and mortality using logistic regression model analysis after propensity score matching with Inverse Probability Treatment Weighting (IPTW) method. Covariates included in the IPTW propensity analysis were: age, sex, body mass index (BMI), initial respiratory rate (iRR), initial pulse oximetry without (SpO2i) and with oxygen supplementation (SpO2i.O2), initial Glasgow coma scale (GCSi) value, initial prehospital SI and initial prehospital lactatemia. RESULTS: We analysed 410 consecutive COVID-19 patients [254 males (62%); mean age, 64 ± 18 years]. Fifty-seven patients (14%) deceased on the scene, of whom 41 (72%) were male and were significantly older (71 ± 12 years vs. 64 ± 19 years; P ã10-3). Fifty-three patients (15%) were admitted in ICU and 39 patients (11%) were deceased on day-30. The mean prehospital SI value was 1.5 ± 0.4 and the mean prehospital lactatemia was 2.0 ± 1.7 mmol.l-1. Multivariate logistic regression analysis on matched population after IPTW propensity analysis reported a significant association between ICU admission and age (adjusted Odd-Ratio (aOR), 0.90; 95% confidence interval (95%CI): 0.93-0.98;p = 10-3), SpO2i.O2 (aOR, 1.10; 95%CI: 1.02-1.20;p = 0.002) and BMI (aOR, 1.09; 95% CI: 1.03-1.16;p = 0.02). 30-day mortality was significantly associated with SpO2i.O2 (aOR, 0.92; 95% CI: 0.87-0.98;p = 0.01 P < 10-3) and GCSi (aOR, 0.90; 95% CI: 0.82-0.99;p = 0.04). Neither prehospital SI nor prehospital lactatemia were associated with ICU admission and 30-day mortality. CONCLUSION: Neither prehospital initial SI nor lactatemia were associated with ICU admission and 30-day mortality among COVID-19 patients initially cared for by a Paris Fire Brigade BLS or ALS team. Further prospective studies are needed to confirm these preliminary results.

BACKGROUND: Emergency physicians can use a manual or an automated defibrillator to provide defibrillation of patients who had out-of-hospital cardiac arrest (OHCA). Performance of emergency physicians in identifying shockable rhythm with a manual defibrillator has been poorly explored whereas that of automated defibrillators is well known (sensitivity 0.91-1.00, specificity 0.96-0.99). We conducted this study to estimate the sensitivity/specificity and speed of shock/no-shock decision-making by prehospital emergency physicians for shockable or non-shockable rhythm, and their preference for manual versus automated defibrillation. METHODS: We developed a web application that simulates a manual defibrillator (https://simul-shock.firebaseapp.com/). In 2019, all (262) emergency physicians of six French emergency medical services were invited to participate in a study in which 60 ECG rhythms from real OHCA recordings were successively presented to the physicians for determination of whether they would or would not administer a shock. Time to decision was recorded. Answers were compared with a gold standard (concordant answers of three experts). We report sensitivity for shockable rhythms (decision to shock) and specificity for non-shockable rhythms (decision not to shock). Physicians were also asked whether they preferred manual or automated defibrillation. RESULTS: Among 215 respondents, we were able to analyse results for 190 physicians. 57% of emergency physicians preferred manual defibrillation. Median (IQR) sensitivity for a shock delivery for shockable rhythm was 0.91 (0.81-1.00); median specificity for no-shock delivery for non-shockable rhythms was 0.91 (0.80-0.96). More precisely, sensitivities for shock delivery for ventricular tachycardia (VT) and coarse ventricular fibrillation (VF) were both 1.0 (1.0-1.0); sensitivity for fine VF was 0.6 (0.2-1). Specificity for not shocking a pulseless electrical activity (PEA) was 0.83 (0.72-0.86), and for asystole, specificity was 0.93 (0.86-1). Median speed of decision-making (in seconds) were: VT 2.0 (1.6-2.7), coarse VF 2.1 (1.7-2.9), asystole 2.4 (1.8-3.5), PEA 2.8 (2.0-4.2) and fine VF 2.8 (2.1-4.3). CONCLUSIONS: Global sensitivity and specificity were comparable with published automated external defibrillator studies. Shockable rhythms with the best clinical prognoses (VT and coarse VF) were very rapidly recognised with very good sensitivity. The decision-making for fine VF or asystole and PEA was less accurate.

BACKGROUND: In December 2019, coronavirus disease (COVID-19) emerged in China and became a world-wide pandemic in March 2020. Emergency services and intensive care units (ICUs) were faced with a novel disease with unknown clinical characteristics and presentations. Acute respiratory distress (ARD) was often the chief complaint for an EMS call. This retrospective study evaluated prehospital ARD management and identified factors associated with the need of prehospital mechanical ventilation (PMV) for suspected COVID-19 patients. METHODS: We included 256 consecutive patients with suspected COVID-19-related ARD that received prehospital care from a Paris Fire Brigade BLS or ALS team, from March 08 to April 18, 2020. We performed multivariate regression to identify factors predisposing to PMV. RESULTS: Of 256 patients (mean age 60 ± 18 years; 82 (32%) males), 77 (30%) had previous hypertension, 31 (12%) were obese, and 49 (19%) had diabetes mellitus. Nineteen patients (7%) required PMV. Logistic regression observed that a low initial pulse oximetry was associated with prehospital PMV (ORa = 0.86, 95%CI: 0.73-0.92; p = 0.004). CONCLUSIONS: This study showed that pulse oximetry might be a valuable marker for rapidly determining suspected COVID-19-patients requiring prehospital mechanical ventilation. Nevertheless, the impact of prehospital mechanical ventilation on COVID-19 patients outcome require further investigations.

Background Although commonly used inside hospitals, no previous case report has been published on high-flow nasal oxygen (HFNO) therapy in an adult in the prehospital setting. Case Report A 46-year-old nonsmoking man presented with a cough and fever. He deteriorated suddenly 5 days later. When the basic life support team arrived, his peripheral oxygen saturation (SpO2) in ambient air was 56% and respiratory rate was 46 breaths/min. The man was weak with thoracoabdominal asynchrony. An emergency medical team with a physician was dispatched. As France was still under lockdown for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic, COVID-19 (coronavirus disease 2019) was suspected. In spite of 15 L/min of oxygen delivered with a nonrebreathing mask, the patient's SpO2 tended to drop below 90% at the slightest effort and during transport from home to the ambulance. It was therefore decided to start HFNO therapy. The patient was transferred to an intensive care unit, where HFNO was continued. Why Should an Emergency Physician Be Aware of This? As the trend in emergency medical services may move toward prehospital HFNO, this case report is an opportunity to question the feasibility of HFNO therapy in the prehospital setting.

BACKGROUND: Western countries report a significant increase in the proportion of patients who experience out-of-hospital cardiac arrests (OHCAs) and benefit from a public automated external defibrillator (pAED) before the arrival of rescue teams. However, recordings of devices recovered after resuscitation are of variable quality. Analysis of these data may inform decisions of whether to implement an internal defibrillator for survivors, and provide useful information about the performance of pAED algorithms and the actions of bystanders. OBJECTIVE: To investigate the quality of the information recorded by pAEDs during OHCAs in the Paris area. METHODS: pAED files used for some of the 8629 OHCAs that occurred in the greater Paris area between 1 January 2017 and 31 April 2019 on the day of the arrest were collected. The presence and accuracy of 23 factors required to interpret the recording was noted, including readability of the ECG, the presence of an impedance curve and the accuracy of the date and time. The recordings were analysed to assess the diagnostic and therapeutic performance of the pAEDs used. RESULTS: A total of 258 patients with an OHCA received assistance from a pAED, and 182 recordings were recovered. The pAEDs were made by 12 different manufacturers. Data extraction required eight different transmission modes and 16 software programmes; recordings were of highly heterogeneous quality. Two per cent of the recordings were of such poor quality that they were not interpretable. Among the 98% remaining, only 43% included a thoracic impedance curve, 34% the intensity of the shocks delivered and 8% the patient name. The date and time were accurate in 68% and 48% of recordings, respectively. The pAEDs had 87.6% (95% CI 83.7% to 91.0%) sensitivity and 99.5% (99.5% to 99.5%) specificity for defibrillating shockable rhythms (positive predictive value 98.2% (96.4% to 99.0%), negative predictive value 96.4% (95.3% to 96.8%)). The absence of important variables prevented the analysis of approximately half of the inappropriate decisions made by pAEDs. CONCLUSION: Collection of pAED recordings is a major challenge. Their analysis is compromised by heterogeneity and poor quality (incomplete maintenance records, patient details and logs). AED recordings are currently the most relevant resource to track pAED performance and bystander practices. The quality of these recordings needs to improve.

Pre-hospital management of a severe burn begins with an early assessment of the burn (burned skin surface, depth, location) and the concerned patient (age, comorbidities, injury associations). The immediate vital prognosis is more often due to associated injuries (trauma or poisoning) rather than burns. The patient must be referred by medical regulation to a burn treatment centre.

INTRODUCTION: Although aneurysmal subarachnoid hemorrhage (SAH) is often complicated by myocardial injury, whether this neurogenic cardiomyopathy is associated with the modification of cardiac metabolism is unknown. This study sought to explore, by positron emission tomography/computed tomography, the presence of altered cardiac glucose metabolism after SAH. METHODS: During a 16-month period, 30 SAH acute phase patients underwent myocardial (18)F- fluorodesoxyglucose positron emission tomography ((18)F-FDGPET), (99m)Tc-tetrofosmin and (123)I-meta-iodobenzylguanidine ((123)I-mIBG) scintigraphy, respectively, assessing glucose metabolism, cardiac perfusion, and sympathetic innervation. Patients with initial abnormalities were followed monthly for two months for (18)F-FDG, and six months later for (123)I-mIBG. RESULTS: In this SAH population, acute cardiac metabolic disturbance was observed in 83% of patients (n = 25), and sympathetic innervation disturbance affected 90% (n = 27). Myocardial perfusion was normal for all patients. The topography and extent of metabolic defects and innervation abnormalities largely overlapped. Follow-up showed rapid improvement of glucose metabolism in one or two months. Normalization of sympathetic innervation was slower; only 27% of patients (n = 8) exhibited normal (123)I-mIBG scintigraphy after six months. Presence of initial altered cardiac metabolism was not associated with more unfavorable cardiac or neurological outcomes. CONCLUSIONS: These findings support the hypothesis of neurogenic myocardial stunning after SAH. In hemodynamically stable acute phase SAH patients, cardiomyopathy is characterized by diffuse and heterogeneous (18)F-FDG and (123)I-mIBG uptake defect. TRIAL REGISTRATION: Clinicaltrials.gov NCT01218191. Registered 6 October 2010.

INTRODUCTION: Face and/or neck burn (FNB) exposes patients to the double respiratory risk of obstruction and hypoxia, and these risks may require a tracheal intubation. This study aims to describe the incidence and the characteristics of difficult intubation in FNB patients. METHODS: We conducted a 5-year retrospective, single-center study including all patients meeting the following criteria: 18 years of age or older, an FNB at least 1% of burned surface area with a severity equal to or greater than the superficial second degree, and intubation and a burn center admission within the first 24 hours after the burn. Patients were compared according to the difficulty of their intubation. RESULTS: Between January 2007 and December 2011, we included 134 patients. The incidence of difficult intubation was 11.2% but was greater in the burn center than in the pre-burn center: 16.9% vs 3.5% (P = .02). The most important difference between patients with or without difficult intubation was the time between the burn injury and the intubation: 210 (105-290) vs 120 (60-180) minutes (P = .047). After multivariate analysis, an intubation performed at a burn center was independently associated with difficult intubation: odds ratio = 3.2; 95% confidence interval, 1.1-528. CONCLUSIONS: This study underlines the high incidence of difficult intubation in FNB patients, greater than 11.2%, and demonstrates that intubation is more difficult when realized at a burn center, probably because it is performed later, allowing for development of cervical and laryngeal edema.

BACKGROUND: The resuscitative endovascular balloon occlusion of the aorta (REBOA) technique controls abdominal, pelvic, junctional, and postpartum hemorrhage via aortic endoclamping. There are no protocols or clear indications guiding REBOA use in a two-tiered prehospital emergency medical system, as found in France. We conducted a Delphi study to clarify the indications and contraindications for REBOA application in such a system. METHODS: We performed a Delphi study in three rounds with an international group of doctors with REBOA expertise and clinical experience (members of the EndoVascular and Trauma Management Society). Based on the consensus answers, complemented by existing data in the literature, we developed a protocol for REBOA use in a medicalized prehospital setting. RESULTS: We identified 10 questions that were not answered in the literature and submitted them to 21 experts. Over three rounds, consensus was reached on these 10 questions. The most important ones were "In your opinion, in a hemorrhagic patient, vascularly well-filled and whose hemodynamics remain unstable with 3mg/h of norepinephrine, should we inflate a REBOA to prevent the patient's death and get them to the operating room alive?" and "In the case of REBOA placement (zone I) in the prehospital setting, would you agree that the maximum occlusion duration is approximately 30 minutes, with a partial or intermittent occlusion when possible?" CONCLUSION: We propose a protocol for REBOA use in a medicalized prehospital setting. This protocol clarifies that hemorrhagic shock, despite a noradrenaline (also known as norepinephrine) dose of 0.6µg/kg/min, is considered too serious for the patient to be transported to the trauma center without REBOA. Moreover, it clarifies that a zone 1 REBOA should be inflated for maximum 30 minutes and with a partial occlusion strategy, if possible. This protocol should be updated based on feedback following the establishment of prehospital REBOA and large randomized studies.
