b'DATA & INNOVATIONThe Impact of CARES DataA series of impactful publications has highlighted the diverse ways in which national CARES data has been used to explore critical issues such as geographic variations in survival outcomes, the effects of public health crises, long-term patient outcomes, and the financial burden of OHCA.One notable study, Outcomes for OHCA in the53.9%U.S. During COVID-19 (Chan, 2020), analyzed the impact of the early COVID-19 pandemic on OHCA outcomes across the U.S. Comparing39.9%data from March 16 to April 30 in both 2019 and 2020, they found that rates of sustained29.8%return of spontaneous circulation (ROSC) were23.0%significantly lower during the pandemic (23.0% in 2020 vs. 29.8% in 2019). This decline was observed nationwide, even in areas with low COVID-199.8% 6.6%mortality rates. Additionally, survival to hospital discharge decreased from 9.8% in 2019 to 6.6% in 2020, primarily in regions with moderate to highSustained ROSC Termination of Resuscitation Survival to DischargeCOVID-19 mortality.Figure 3. Rates of Sustained ROSC, Termination of Resuscitation, Survival to Discharge During the 2020 Pandemic vs 2019.Figure 3 highlights these key metrics. The study also noted an increase in OHCA incidence,12particularly in communities with high COVID-19 mortality. These findings suggest that the10pandemic adversely affected OHCA outcomes across the country, not solely in areas heavily8$ Billion USDimpacted by COVID-19, and documented how emergency response disruptions contributed6to increased mortality and delays in care. This publication emphasized the need for4preparedness and resilience in public health systems to better respond to such global2crises. 1Following this, Annual and Lifetime Economic0 2013 2014 2015 2016 2017 2018Productivity Loss Due to OHCA (Coute, 2021)CARES Population US Populationexamined the economic burden of OHCA inFigure 4.

Findings showed that OHCA results in substantial productivity losses, amounting to billions of dollars annually, emphasizing the economic justification for increased investment in prevention, early intervention, and public access defibrillation programs. For the U.S. population, the total annual economic productivity loss increased from $7.4B in 2013 to $11.3B in 2018 (fig. 4). 54'
