Beck S, Doehn C, Funk H, et al. - Researchers examined how training on shared mental models influence team performance in simulated in-hospital cardiac arrest. They performed a randomized controlled trial to compare two training methods [a conventional instructor-led training and an interventional training] on the background of an introduction of mandatory basic life support (BLS) training for clinical staff. Staff from clinical departments received either a conventional instructor-led training (control group) or an interventional training (intervention group). BLS training for clinical staff which creates shared mental models reduces hands-off time in a simulated cardiac arrest scenario. Training methods establishing shared mental models of team members can be considered for effective team trainings without adding additional training time. Comparing the performance of 75 teams of the interventional and 66 of the control group, they identified significantly lower hands-off time in the interventional group. They observed a significant negative correlation of hands-off time with all team assessment scale items. Findings support considering training methods establishing shared mental models of team members for effective team trainings without adding additional training time.
