Improving Temporal Trends in Survival and Neurological Outcomes After Out-of-Hospital Cardiac Arrest

Abstract

Survival after OHCA has improved over time. This trend was associated with improved rates of bystander CPR, automated external defibrillator use, high-quality CPR metrics, and in-hospital targeted temperature management. The results suggest that multiple factors, each improving over time, may have contributed to the observed increase in survival.
