CARES stands for the Cardiac Arrest Registry to Enhance Survival. CARES is a collaborative effort of the Centers for Disease Control and Prevention (CDC) and Emory University, Woodruff Health Sciences. The ultimate goal of CARES is to improve survival from sudden cardiac death. The registry is designed to help local EMS administrators and medical directors identify who is affected, when and where cardiac arrest events occur, which elements of the system are functioning properly and which elements are not, and how changes can be made to improve cardiac arrest outcomes. CARES utilizes an internet database system that reduces time involved in registering out-of-hospital cardiac arrest (OHCA) events, tracking patient outcomes with hospitals prospectively, and response time intervals associated with First Responder and EMS agencies.
