Introduction: This study evaluated the impact of an emergency department (ED) closure on out-of-hospital cardiac arrest survival outcomes and the emergency medical service system in Ulsan, South Korea. Methods: We conducted a retrospective observational cohort study from March 2017 to February 2021 and compared survival to hospital discharge and favorable neurological outcomes. We investigated transport time intervals (TTIs) in the total study population and subgroup covered by the closed ED. The analysis methods included propensity score matching (PSM), inverse propensity weighting (IPW), and logistic regression analysis. Results: The study included 692 and 920 patients before and after ED closure groups, respectively. After adjusting for covariates, the adjusted odds ratios and 95 % confidence interval for survival discharge and favorable neurological outcomes were 1.040 (0.749–1.444, p = 0.814) and 2.845 (1.563–5.177, p = 0.001), respectively. PSM showed values of 1.015 (0.727–1.416, p = 0.932) for discharge survival and 1.777 (1.074–2.941, p = 0.025) for neurological outcomes. IPW showed values of 0.980 (0.762–1.261, p = 0.875) for discharge survival and 1.782 (1.196–2.656, p = 0.005) for neurological outcomes. The TTI increased from 5.8 ± 5.0 to 6.7 ± 5.5 min (p |
