Dispatcher-assisted cardiopulmonary resuscitation for out-of-hospital cardiac arrest patients: a site-level analysis of the PAROS trial.

ABSTRACT:

Objectives

The study aimed to examine the influence of contextual settings on the complex OHCA intervention outcomes thereby providing evidence to guide managers and policymakers in optimizing implementation strategies. Our secondary analysis of an international multi-site trial examined site-level effectiveness of comprehensive versus basic Dispatcher-Assisted CPR (DACPR) interventions on bystander CPR rates, hypothesizing site-specific variation and declining variability as an early sign.

Methods

Using 2009-2018 data from the Pan-Asian Resuscitation Outcomes Study (PAROS), we compared monthly and quarterly trends in BCPR rates at selected PAROS sites before and after the intervention. Interrupted time series analysis was performed using regression of monthly BCPR rates for
