Background: Worldwide, bystander CPR rates are low; one effective way to increase these rates is to train schoolchildren; however, the most effective way to train them is currently unknown.
Methods: This systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies, evaluated whether CPR training for schoolchildren, using innovative teaching modalities (nonpractical, self, or peer-training) versus standard instructor-led training, resulted in higher quality CPR, self-confidence and short-term (≤3 months post-training) or long-term (>3 months post-training) retention of CPR skills.
Results: From 9793 citations, 96 studies published between 1975 and 2022 (44 RCTs and 52 before/after studies) were included.
