FIRECARE: An Evidence-Based Prevention Program to Reduce Burnout among Prehospital Caregivers: Benefits of a Combined Mindfulness, Heart Coherence Training, and Positive Psychology Intervention.

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.

Hands-off Time during Automated Chest Compression Device Application in Out-of-Hospital Cardiac Arrest: A Case Series Report.

INTRODUCTION: During out-of-hospital cardiac arrest (OHCA), chest compression interruptions or hands-off time (HOT) affect the prognosis. Our aim was to measure HOT due to the application of an automated chest compression device (ACD) by an advanced life support team. MATERIALS AND METHODS: This was a prospective observational case series report since the introduction of a new method of installing the ACD. Inclusion criteria were patients over 18 years old with OHCA who were treated with an ACD (Lucas 2(TM), Physio-Control). The ACD application was indicated only for OHCA patients transported to a hospital for Extra Corporeal Life Support (ECLS). We recorded the HOT related to switching from manual to mechanical chest compressions. An ACD consists of dorsal and ventral components, which can be installed either in one or in two steps, separated from a chest compression sequence. HOT was expressed as a median number of seconds [interquartile range]. RESULTS: From January 1, 2012 to January 15, 2013, 30 patients were included. In the case of ACD application in one phase (n = 16), the median HOT was 25.3 s [19.8-30.5]. With regard to patients with an ACD application in two phases (n = 14), the median HOT was, respectively, 9.8 s [7.8-17] and 12.4 s [9.5-16.2], that is, a median global HOT of 23.6 s [19-27.6]. HOT was not different between ACD applications in one or two phases (p = 0.52). For a two phase application, the median chest compression time between the two manipulations was 14.2 s [6.4-18]. CONCLUSION: There was no significant difference between techniques in the application of the Lucas 2(TM) device in terms of HOT. The short time needed to apply the device lends itself well to use as a primary chest compression modality during cardiac arrest as well as a bridge to novel resuscitation strategies (ECLS). A further study is currently underway with a larger number of ECLS patients.

Maxillofacial gunshot wounds.

The majority of maxillofacial gunshot wounds are caused by suicide attempts. Young men are affected most often. When the lower one-third of the face is involved, airway patency (1.6% of the cases) and hemorrhage control (1.9% of the cases) are the two most urgent complications to monitor and prevent. Spinal fractures are observed with 10% of maxillary injuries and in 20% of orbital injuries. Actions to treat the facial gunshot victim need to be performed, keeping in mind spine immobilization until radiographic imaging is complete and any required spinal stabilization accomplished. Patients should be transported to a trauma center equipped to deal with maxillofacial and neurosurgery because 40% require emergency surgery. The mortality rate of maxillofacial injuries shortly after arrival at a hospital varies from 2.8% to 11.0%. Complications such as hemiparesis or cranial nerve paralysis occur in 20% of survivors. This case has been reported on a victim of four gunshot injuries. One of the gunshots was to the left mandibular ramus and became lodged in the C4 vertebral bone.

Analysis during chest compressions in out-of-hospital cardiac arrest patients, a cross/sectional study: The DEFI 2022 study.

AIMS: During out-of-hospital cardiac arrest (OHCA), an automatic external defibrillator (AED) analyzes the cardiac rhythm every two minutes; however, 80% of refibrillations occur within the first minute post-shock. We have implemented an algorithm for Analyzing cardiac rhythm While performing chest Compression (AWC). When AWC detects a shockable rhythm, it shortens the time between analyses to one minute. We investigated the effect of AWC on cardiopulmonary resuscitation quality. METHOD: In this cross-sectional study, we compared patients treated in 2022 with AWC, to a historical cohort from 2017. Inclusion criteria were OHCA patients with a shockable rhythm at the first analysis. Primary endpoint was the chest compression fraction (CCF). Secondary endpoints were cardiac rhythm evolution and survival, including survival analysis of non-prespecified subgroups. RESULTS: In 2017 and 2022, 355 and 377 OHCAs met the inclusion criteria, from which we analyzed the 285 first consecutive cases in each cohort. CCF increased in 2022 compared to 2017 (77% [72-80] vs 72% [67-76]; P < 0.001) and VF recurrences were shocked more promptly (53 s [32-69] vs 117 s [90-132]). Survival did not differ between 2017 and 2022 (adjusted hazard-ratio 0.96 [95% CI, 0.78-1.18]), but was higher in 2022 within the sub-group of OHCAs that occurred in a public place and within a short time from call to AED switch-on (adjusted hazard ratio 0.85[0.76-0.96]). CONCLUSIONS: OHCA patients treated with AWC had higher CCF, shorter time spent in ventricular fibrillation, but no survival difference, except for OHCA that occurred in public places with short intervention time.

Exposure to fire smoke in fire training structures: A prospective observational study.

The aim of this study was to assess the level of exposure to and contamination by smoke within a population of firefighter instructors. We performed a prospective observational study from September 17 to September 26, 2018, using environmental samples and urinary biomarker analysis. Occupational exposure limits (OELs) were never exceeded, except for carbon monoxide for the fire attack training chamber and formaldehyde and carbon monoxide for the fire box. As regards to urinary biomarkers, we observed that 1OHP and 1-naphtol did accumulate. The pre-post analysis showed an acute exposure exceeding the BRVs of benzene, 1-hydroxypyrene and naphtol, except for 3-benzo[a]pyrene which was undetectable in half of the cases. Even if values were reassuring, an effort could be made to improve the working conditions and reduce contamination by rethinking the respiratory protection and improving PPE quality.
