Whether schools should require CPR/AED training is decided at the state level, and there are variations in legislative mandates across the nation. As of December 31, 2020, 39 out of 50 states and the District of Columbia mandated CPR and AED training for high school students. Associations between law status and OHCA intervention rates were therefore studied using the CARES data. All nontraumatic OHCAs from states with at least 50% population catchment during the study period were eligible for inclusion. Using the deterministic method of linkage, information on state-level CPR/AED training mandates was linked to the CARES dataset, de-identified in-house prior to analysis. More than one-half of OHCAs occurred in states with laws enacted (56.6%). Findings highlight that patients with an OHCA were more likely to receive bystander CPR (bCPR) over all age ranges (except for 13-17 years) in states with a law enacted compared to states without a law enacted. Furthermore, in states with CPR/AED training laws compared to those without laws, a greater percentage of patients who experienced OHCAs received bCPR regardless of gender, race, ethnicity (except Hispanic/other), arrest witness status (witnessed/unwitnessed), location of arrest (public/residential), or initial presenting cardiac rhythm (shockable/nonshockable). Additionally, the use of AEDs for public OHCA was also higher in states with CPR/AED training laws. These findings indicate that the association between law status and bCPR is at least partially explained by legislative mandates.Without data linkage, healthcare initiatives fail to utilize the significant potential of rapidly growing data resources to enhance the well-being of the public. As a result, incomplete data will continue to be the basis for clinical or policy decisions. Linking different datasets together facilitates the identification of patterns and allows for validation across datasets as well as the exploration of various influences on out-of-hospital cardiac arrest survival, enabling more informed decision-making.
