b"DATA & INNOVATIONFigure 1. Map of 2024 CARES ParticipantsThe program has proven to be a powerful tool for improving survival outcomes from OHCA across various regions as well. Alaska and Chicago are prime examples of how leveraging the CARES Quality Improvement Program has emphasized the critical role of data in driving targeted interventions that enhance survival outcomes across diverse communities. In Alaska, participation in CARES has significantly impacted how OHCA cases are managed. The Municipality of Anchorage began contributing data to CARES, allowing local EMS, hospitals, and community stakeholders to track performance across the chain of survival. This access to standardized data provided critical insights into local OHCA trends, which were previously difficult to assess due to the state's geographic challenges. CARES data revealed areas where interventions could improve survival rates, highlighting opportunities to increase bystander CPR rates and public access to AEDs. In response, Anchorage implemented community-focused CPR training initiatives, expanded AED placement, and enhanced dispatcher-assisted CPR (DACPR) protocols. CARES data also helped EMS agencies refine response strategies, ensuring rapid defibrillation and high-quality CPR were prioritized. Hospitals standardized post-resuscitation care, including therapeutic hypothermia and cardiac catheterization procedures. As a result, Anchorage achieved higher survival rates than the national average, particularly for witnessed arrests with shockable rhythms. The programs benchmarking capabilities allowed Alaska's emergency response system to share successes and refine protocols, demonstrating how data-driven approaches can overcome logistical challenges. 56"
