Abstract: Aims: This study aims to test the association between the place-provider-matrix (PPM) of bystander cardiopulmonary resuscitation (CPR) and outcomes of out-of-hospital cardiac arrest (OHCA). Methods: Adult patients with OHCA with a cardiac etiology from 2012 to 2017 in Korea were analyzed, excluding patients who had unknown information on place, type of bystander, or outcome. The PPM was categorized into six groups by two types of places (public versus home) and three types of providers (trained responder (TR), family bystander, and layperson bystander). Outcomes were survival to discharge and good cerebral performance category (CPC) of 1 or 2. Multivariable logistic regression analysis was performed to test the association between PPM group and outcomes with adjustment for potential confounders to calculate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) (reference = Public-TR). Results: A total of 73,057 patients were analyzed and were categorized into Public-TR (0.6%), Home-TR (0.3%), Public-Family (1.8%), Home-Family (79.8%), Public-Layperson (9.9%), and Home-Layperson (7.6%) groups. Compared with the Public-TR group, the AORs (95% CIs) for survival to discharge were 0.61 (0.35–1.05) in the Home-TR group, 0.85 (0.62–1.17) in the Public-Family group, 0.38 (0.29–0.50) in the Home-Family group, 1.12 (0.85–1.49) in the Public-Layperson group, and 0.42 (0.31–0.57) in the Home-Layperson group. The AORs (95% CIs) for good CPC were 0.58 (0.27–1.25) in the Home-TR group, 0.88 (0.61–1.27) in the Public-Family group, 0.38 (0.28–0.52) in the Home-Family group, 1.20 (0.87–1.65) in the Public-Layperson group, and 0.42 (0.30–0.59) in the Home-Layperson group. Conclusion: The OHCA outcomes of the Home-Family and Home-Layperson groups were worse than those of the Public-TR group. This finding suggests that OHCA occurring in private places with family or layperson bystanders requires a new strategy, such as dispatching trained responders to the scene to improve CPR outcomes.
