Texas-CARES measures systems of care for effectively responding to cardiac arrests by using the Cardiac Arrest Registry to Enhance Survival (CARES).

The Cardiac Arrest Registry to Enhance Survival was established by the U.S. Centers for Disease Control and Prevention and Emory University to improve survival from cardiac arrest through out-of-hospital cardiac arrest (OHCA) data collection in the United States. Communities that join CARES commit to entering cardiac arrest data from EMS agencies and hospitals into a national database in order to track their performance confidentially over time and improve the quality of patient care—and ultimately prevent needless deaths.
