Outcome of basic life support training among primary school students in Southeast Asia

This study aimed to evaluate how BLS courses affect primary school students' knowledge, attitudes, and life support skills; investigate how medical students' knowledge and competence in teaching BLS can improve by serving as instructors.

This experimental study was conducted in a rural primary school. First-year medical students conducted a BLS course for grade 4 and 5 primary school students with a 6-7:1 ratio of trainees-to-trainer. All trainers had completed a BLS course before the course. This 3.5-hour simulation-based course covered chest compressions and automated external defibrillator use. The pre- and post-course assessments included multiple choice questions toward BLS, practical skills test, and attitude test. For medical students, evaluation was conducted by attitude test, both pre- and post-teaching.

The mean pre- and post-test scores increased from 5.74±0.10 to 9.43±0.13 (P<0.01). The increase in the scores was the same for both the students and the teachers (3.05±0.60 vs. 3.68±0.16, P=0.33). After the course, more than 90% of the students could perform all the procedures involved in BLS and automated external defibrillation. Medical students showed an improved understanding of CPR and confidence in performing and teaching CPR (both, P<0.01).

Primary school students can learn how to perform BLS through simulation-based learning. Simulation-based training can improve their attitude and provide them with knowledge and crucial skill sets, improving their confidence in performing BLS. Furthermore, teachers' attitudes and confidence toward CPR improved after teaching CPR.
