We tested the Basic-SiM train-the-trainer simulation-based resuscitation training module among airline instructors to train the cabin crew in Malaysia. Selected airline instructors were asked to attend a Train-The-Trainer course and then use the knowledge to test their airline cabin crews who were divided into 2 different groups (n=65) using different debriefing methods (customary vs DIAMOND) at both the baseline and at 6 weeks post-intervention on resuscitation knowledge and technical and non-technical skills through a MCQ test, TSTC, and CETAM. There were no significant differences in terms of the different debriefing methods on the improvement of all variables except for technical skills in both groups, F(3,123) =0.540, P=0.656, and partial eta squared=0.013 despite retention for all variables. This module is an effective approach to develop trainers for simulated resuscitation training and was proven to be effective in improving the knowledge and skills of cabin crew in Malaysia.
