BACKGROUND: Although basic life support (BLS) has been taught in school by a variety
of professionals, it is still unclear that, whether the instructor’s previous cardiopulmonary
resuscitation (CPR) experience is an important factor. This study aimed to compare the effect of
BLS training, based on trainer experience in actual situations, on knowledge and skills of secondary
high school students.
MATERIALS AND METHODS: In this randomized controlled trial, 150 high school students were
selected based on the inclusion criteria and then assigned into two groups, (76 in Group A), and (74
in Group B) randomly. Both groups were trained according to adult BLS: 2020 American Heart
Association guidelines on mannequins in three 60 min in‑person training sessions. The knowledge
and skill scores were measured for both groups before, immediately, and 1 month after intervention
by a questionnaire. Data were analyzed by the SPSS software version 22, using Chi‑square,
Mann–Whitney U, repeated‑measure ANOVA tests, and statistically modeling at a significance
level of 0.05.
RESULTS: There were no significant differences between groups regarding demographic
characteristics. The knowledge and skill scores in both groups increased significantly compared
to baseline immediately and 1 month after the intervention (P = 0.001). However, there was no
significant difference in knowledge scores between groups (P = 0.076(. However, at the immediacy
and 1 month after the intervention, the skill score in “Group A” was significantly higher than the
“Group B” (P = 0.001).
CONCLUSIONS: The trainer’s experience of CPR in the actual setting in the transfer of BLS
knowledge is not important, but it improved Student’s BSL skill acquisition score.
