Annually in the United States, roughly 350,000 people suffer Out of Hospital Cardiac Arrest (OHCA) events. Survival rates, as well as patient outcomes, are incredibly poor following these events with only 10.4% of patients able to be discharged after OHCA occurs ( Due to this fact, cities across the United States have implemented the Cardiac Arrest Registry to Enhance Survival (CARES), a program striving to reduce deaths from OHCA. CARES has had a substantial impact on the survival rates of OHCA due to their improvements to emergency cardiac care. To demonstrate this, we will present case studies that show CARES effectiveness and provide evidence in favor of mandatory adoption of the CARES system nationally. Currently the CARES system operates by helping coordinate information between EMS organizations, 911 dispatchers, and onboarding hospitals. An annual report on the OHCA patient outcomes is then compiled using the data collected. The report “automatically calculates local 911 response intervals, delivery rates for critical interventions (e.g., bystander CPR and public access defibrillation [PAD]), and community rates of survival and functional status at discharge” ( Our research conducted on these reports will show the benefits that the CARES system has had on the cites and states that have adopted the system. We will provide evidence for the expansion of the CARES system across the United States despite the monetary costs of the system in order to help prevent sudden cardiac arrest deaths.
