Impact of a Multidisciplinary Simulation-Based Training Program on the Multiple Techniques of Intraosseous Access: A Prospective Multicentric Study.

OBJECTIVES
The aim of this study was to assess intraosseous (IO) access placement performance during a multidisciplinary simulation-based training (SBT) program according to the professional status, experience of caregivers, and the setting of the course.


METHOD
This prospective, multicentric study included emergency physicians, residents, certified registered nurse anesthetists, registered nurses, and students. It was carried out between April 6, 2020 and April 30, 2021 in emergency medical services, an emergency department, and a simulation center. Trainee performance was evaluated by 2 independent observers using a validated scale, before and after SBT. Self-assessment of satisfaction was carried out. Interobserver reproducibility was analyzed by intraclass correlation coefficient. The continuous variables were compared using a Student t test or a nonparametric Mann-Whitney U test. Comparative analysis between the different groups used analysis of variance. Correlation analysis was performed by a nonparametric Spearman test. A P value of 0.05 was considered significant.


RESULTS
Ninety-eight participants were included. Intraclass correlation coefficient between the 2 observers was 0.96. Performance significantly increased after training, regardless of the site or device used (for the semiautomatic device, P = 0.004 in tibia and P = 0.001 in humeral; for the manual device, P < 0.001). Simulation-based training significantly reduced time for IO access (P = 0.02). After SBT, no difference was found according to professional status and the setting of the course. Performance was not correlated with professional experience. All trainees were satisfied with the training.


CONCLUSIONS
Simulation-based training improved the IO access using a semiautomatic or a manual device, regardless of the experience or status of the trainees. Simulation-based training would work for many disciplines regardless of locations (simulation or clinical facilities).
