A comparison between conventional BLS course and distributed CPR training

Content	BLS course (standardised 4 hours)	Workplace-based distributed CPR training with real-time feedback
Didactic teaching	50 min (standardised video)	60 min* (Online learning)
CPR practice	40 min	12×5=60 min
AED practice	10 min	0 min
Other logistics	85–90 min (waiting, observing, course break, questions and answers, etc)	5–10 min (orientation to the equipment)

*Didactic teaching for guidelines was covered by online training material for the intervention group. Instead of watching the videos in the classroom, participants watch this content using their spare time. Costs of didactic teaching is calculated as the costs of online material. In our local setting, time spent on online module was not compensated, therefore not calculated in the base case. However, the situation when online learning time is paid by the hospital is explored in the one-way sensitivity analyses.

AED, automatic external defibrillator; BLS, basic life support; CPR, cardiopulmonary resuscitation.
