Cohort study finds higher basic life support training rates correlate with improved 30-day cardiac arrest survival, suggesting benefits extend beyond increased bystander CPR rates alone.
In this cohort study of Danish BLS course participation and survival, a positive association was found between annual rate of mass education in BLS and 30-day survival from OHCA. The association of BLS course participation rate on 30-day survival was mediated by the bystander CPR rate; approximately 60% of the association of BLS course participation rate on 30-day survival was based on factors other than increased CPR rates.
