Association of health insurance with post-resuscitation care and neurological outcomes after return of spontaneous circulation in out-of-hospital cardiac arrest patients in Korea.

Abstract

We investigated the association of health insurance status with post-resuscitation care and neurological recovery in out-of-hospital cardiac arrest (OHCA) and whether the effects changed with age or gender. Adult OHCAs with presumed cardiac etiology who had sustained ROSC from 2013 to 2016 were enrolled from the nationwide OHCA registry of Korea. Insurance status was categorized into 2 groups: National Health Insurance (NHI) and Medical Aid (MA). The endpoints were post-resuscitation coronary reperfusion therapy (CRT), targeted temperature management (TTM), and good neurological recovery (cerebral performance category of 1 or 2). Multivariable logistic regression models and interaction analyses (insurance × age and insurance × gender) were conducted for adjusted odds ratios (aORs) and 95% confidence intervals (CI). Of a total of 19,865 eligible OHCA patients, 18,119 (91.2%) were covered by NHI and 1746 (8.8%) by MA. The MA group was less likely to receive post-resuscitation CRT and TTM (aOR (95% CI): 0.75 (0.59-0.96) for CRT; 0.71 (0.57-0.89) for TTM) and had worse neurological outcomes (0.71 (0.57-0.89)) compared with the NHI group. In the interaction analyses, MA was associated with less CRT and good neurological recovery in the 45-64 year old group (0.54 (0.37-0.77) for CRT; 0.70 (0.51-0.95) for neurological outcome) and in the male group (0.69 (0.52-0.91) for CRT; 0.77 (0.61-0.97) for TTM; 0.70 (0.53-0.92)) for neurological outcome). There were disparities in post-resuscitation care and substantial neurological recovery by health insurance status, and the disparities were prominent in middle-aged adults and males. Increasing health insurance coverage for post-resuscitation care should be considered.
