Stroger, Jr. Hosp, Chicago, IL; Terry L Vanden Hoek, UNIVERSITY ILLINOIS CHICAGO, Chicago, IL Background: Nearly 1000 cardiac arrest cases are reported in the US every day, and 70-90% of the cases die before reaching the hospital. In this study, we aimed to describe trends in mean age of cardiac arrest in Chicago. Method: We analyzed adult out-of-hospital cardiac arrest (OHCA) cases reported to Cardiac Arrest Registry to Enhance Survival (CARES) database and served by Chicago Emergency Medical Services from 2014-2021. We excluded pediatric cases, and cases with missing age. The annual data were combined to create two-year cycles. The trends in the mean age of cardiac arrest cases were calculated using linear regression models. Results: 21,532 OHCA cases occurred during 2014-2021, and 61% were males, 57% Black, 26% White, 12% Hispanic/Latino and 5% Others. The mean age of OHCA was 62.9 years. The mean age decreased from 64.7 (in 2014-2015) to 61.5 (in 2020-2021) with a biennial change of -1.1 (p<0.01). The median age followed the same pattern with a decrease from 65 (in 2014-2015) to 62 years (in 2020-2021). Similar trends were noticed by gender. The mean age decreased in males (biennial change of -1.2; p<0.01) and in females (biennial change=-0.6; p<0.01) but was less pronounced in females. The mean age decreased significantly in White, Black, and Hispanic/Latino cases. However, in Asian cases, even though a decrease was noticed, it was not statistically significant. The largest decrease in mean age was in Black cases (biennial change of -1.2; p<0.01), followed by Hispanic/Latino cases (-0.7; p=0.03). When examined by race/ethnicity and gender, Black male cases had the largest decrease in mean age at cardiac arrest (-1.4; p<0.01). Conclusion: This analysis presents a concerning trend and speaks to the need for additional research and surveillance mechanisms to identify people at risk for OHCA. Early age at cardiac arrest could mean more years of potential life lost (YPLL). Changes in YPLL and disability-adjusted life years should also be explored in future studies.
