Comparative evaluation of video-based on-line course versus serious game for training medical students in cardiopulmonary resuscitation: A randomised trial

PURPOSE: To estimate the effect size of a serious game for cardiopulmonary resuscitation (CPR) training in comparison with a video-based on-line course in terms of learning outcomes among medical students before simulation-based CPR using a manikin. METHODS: Participants were 45 first-year medical students randomly assigned to CPR self-training using either a video-based Apple Keynote presentation (n = 22) or a serious game developed in a 3D learning environment (n = 23) for up to 20 min. Each participant was evaluated on a written, multiple-choice test (theoretical test) and then on a scenario of cardiac arrest (practical test) before and after exposure to the self-learning methods. The primary endpoint was change in theoretical and practical baseline scores during simulated CPR. This study was conducted in 2017. RESULTS: Both groups improved scores after exposure. The video group had superior performance in both the theoretical test (7.56±0.21 vs 6.51±0.21 for the game group; p = 0.001) and the practical test (9.67±0.21 vs 8.40±0.21 for the game group; p < 0.001). However, students showed a preference for using games, as suggested by the longer time they remained interested in the method (18.57±0.66 min for the game group vs 7.41±0.43 for the video group; p < 0.001). CONCLUSIONS: The self-training modality using a serious game, after a short period of exposure, resulted in inferior students’ performance in both theoretical and practical CPR tests compared to the video-based self-training modality. However, students showed a clear preference for using games rather than videos as a form of self-training.
