2025 CARES DATASET
Incidence and Demographics
This report presents CARES data from the most recent calendar year, January 1 to December 31, 2025. To 
be included in the annual National Report, EMS agencies must enter at least one complete calendar year 
of data and meet a patient lost-to-follow-up threshold of less than 1%. The CARES 2025 National Reports 
are available for viewing at: https://mycares.net/sitepages/reports2025.jsp. 
The 2025 dataset includes 2,694 EMS Agencies and 2,279 Hospitals, and represents a population of 
175.8 million, approximately 52% of the U.S. population. In 2025, 140,427 OHCA events were reported to 
CARES. The crude incidence of non-traumatic, worked arrests was 79.9 per 100,000, slightly higher than 
the incidence rate of 78.7 per 100,000 observed in 2024. Using census data to extrapolate to the U.S. 
population1, CARES estimates that there were approximately 271,641 EMS-treated, non-traumatic OHCA 
cases in the United States last year.
2025 Dataset and Incidence of OHCA Events
In 2025, the majority of CARES patients were male (62.7%). Of the reported OHCA events, 97.4% 
(n=136,766) were adults and 2.6% (n=3,625) were children, aged 18 years and younger. The median 
age of OHCA patients was 67.0 years (mean: 63.6; standard deviation: 18.8). The age distribution varied 
significantly between males and females (Figure 2), with females having a higher median age of arrest 
(68.0 vs 66.0 years, p<.0001).
