The Cardiac Arrest Registry to Enhance Survival (CARES) is a program to link out-of-hospital cardiac arrest cases with their EMS care to hospital outcomes through a secured, web-based database. As one of the largest EMS registries in the world, participation in CARES has helped to improve patient outcomes, increase community health education efforts, and equip first responders with life-saving tools. In late 2021, New York joined 29 other states and 50 communities in 16 additional states as a statewide program, based in Buffalo through UBMD Emergency Medicine.

Participation is free for all New York State EMS agencies, hospitals, and 911 dispatch centers.
