This study aimed to investigate accessibility for rehabilitation therapy according to socioeconomic status (SES) after stroke using nationwide population-based cohort data. We selected patients with a diagnosis with stroke (International Classification of Diseases, 10th Revision code: I60-64) and SES including residential area, income level, and insurance type were also assessed. Receiving continuous rehabilitation therapy was defined as accumulation of "Rehabilitative developmental therapy for disorder of central nervous system (claim code: MM105)" more than 41 times. Logistic regression analyses were performed to investigate the association between SES and rehabilitation therapy using odds ratios (ORs) and 95% confidence intervals (CIs). A total of 18,842 patients with stroke were enrolled. Rural area (OR, 0.745; 95% CI, 0.664-0.836) and medical aid (OR, 0.605; 95% CI, 0.494-0.741) were associated with lower rate of receiving rehabilitation therapy. As for income level, when lowest income group was used as a reference group, low-middle group showed an increased rate of receiving rehabilitation therapy (OR, 1.206; 95% CI, 1.020-1.426). Although rehabilitation therapy after stroke is covered with national health insurance program in Korea, there still existed disparities of accessibility for rehabilitation therapy according to SES. Our results would suggest helpful information for health policy in patients with stroke.
