The incidence of out-of-hospital cardiac arrest in Korea increased from 48.2 to 66.7 per 100,000 between 2008 and 2017, while age- and sex-adjusted mortality decreased (p for trend <0.0001).

What are the 10-year epidemiologic trends and outcomes of non-traumatic out-of-hospital cardiac arrest in Korea?
Over a 10-year period in Korea, the incidence of out-of-hospital cardiac arrest increased, but the 1-year mortality rate gradually improved.
Hazard Ratio: 0.9629
p-value: p=<0.0001
BACKGROUND AND OBJECTIVES: It is crucial to understand the exact public health burden of out-of-hospital cardiac arrest (OHCA) cases; this is presently unknown since sufficient episodes are not reported in registry studies. We aimed to evaluate the epidemiologic features and outcomes of non-traumatic OHCA. METHODS: During January 2008 to December 2017, we enrolled 387,665 patients who had been assigned a code for sudden cardiac arrest or had undergone cardiopulmonary resuscitation in the emergency room using the Korean National Health Insurance Service database. Those whose arrest was of non-cardiac origin were excluded. RESULTS: The incidence of OHCA per 100,000 patients increased steadily from 48.2 in 2008 to, 53.8 in 2011, 60.1 in 2014, and 66.7 in 2017, with a 1-year survival rate of 8.2%. Age and sex-adjusted mortality rates showed a decreasing trend. The hazard ratio was 1.0015 in 2009, 0.9865 in 2012, 0.9769 in 2015, and 0.9629 in 2017 (p for trend <0.0001), with coronary artery disease-related OHCA accounting for 59.8% of the total. Subgroups with coronary artery disease-related OHCA were more likely to be older and have a higher prevalence of all related comorbidities, excluding malignancy, than those with non-coronary artery disease-related OHCA. CONCLUSIONS: This nationwide population-based study showed that the incidence of OHCA in Korea had increased during the last decade. The post OHCA 1-year mortality rate showed a poor outcome but improved gradually.
Roh et al. (Fri,) conducted a cohort in Non-traumatic out-of-hospital cardiac arrest (n=387,665). Year of arrest (2008-2017) vs. Earlier years (trend over time) was evaluated on Age and sex-adjusted mortality rate (HR 0.9629, p=<0.0001). The incidence of out-of-hospital cardiac arrest in Korea increased from 48.2 to 66.7 per 100,000 between 2008 and 2017, while age- and sex-adjusted mortality decreased (p for trend <0.0001).
