Does basic life support training increase OHCA victims’ chances of survival?. Lafrance, M. June, 2022. abstract bibtex Introduction: ERC encourages massive training in basic life support (BLS) for laypeople. Our study aim was to assess impact of bystander’s BLS training level on survival after an out-of-hospital cardiac arrest (OHCA). Materials and Methods: Data was gathered through the French national OHCA registry (RéAC) between 07/2011 and 09/2021. We compared patients when bystander was BLS-trained vs untrained. In a sub-group analysis, same comparisons were performed only when bystander initiated a CPR. Results: We included 2,944 patients, bystander was BLS-trained in 80.9% of cases (2,381 patients) and untrained in 19.1% (563 patients). In the BLS-trained group, OHCA etiology was less often medical (83.5% vs 88.8%, p=0.002). Bystanders were less often family members (37.3% vs. 59.9%, p\textless10-3) and more likely to initiate BLS (55.9% vs. 49.9%, p\textless10-3). CPR was less performed by EMS (77.8% vs 82.2%, p=0.025), no- and low-flow were lower (3min vs 6min, p=0.025 and 30min vs 33min, p\textless10-3 respectively), the first recorded cardiac rhythm at EMS arrival was less often an asystole (69.5% vs. 73.2%, p=0.011) and adrenaline was less often injected (67% vs. 72.1%, p=0.024). ROSC and D0 survival rates were higher when bystander was BLS-trained (33.1% vs 27.4%, p=0.011 and 29.9% vs 23.8%, p=0.005 respectively). Survival rates at D30 were not different. In the subgroup analysis, when CPR was performed by a BLS-trained bystander, ROCS and D0 survival rates were higher (39.4% vs. 32.2%, p=0.011 and 36.1% vs. 28.3%, p=0.004 respectively). D30 survival rates were not different. Conclusion: When bystander is BLS-trained, BLS is more often initiated and no- and low-flow durations are reduced, then, asystoles’ frequency is also reduced. When bystander initiated BLS, his training increases patient’s survival chances. The development of these massive trainings is necessary to optimize OHCA victims’ survival chances. Furthermore, studies focuses on skills retention in trainings would be necessary.
