Trends in Acute Care and Rehabilitation for First-Ever Stroke Patients: A 12-Year Perspective, the KOSCO Study

Updated data on stroke care trends are crucial for advancing stroke treatment. This study aimed to assess trends in inpatient care for first-ever stroke patients in South Korea over a 12-year period, focusing on demographic shifts and acute treatments including rehabilitation.

This multicenter cohort study analyzed first-ever stroke patients admitted to three representative hospitals in South Korea during 2008 (n = 911), 2014 (n = 1,489), and 2020 (n = 1,434). The 2008 data were collected retrospectively, while 2014 and 2020 data were obtained from a prospective cohort study. Data included demographics, risk factors, stroke characteristics, hospital course, and rehabilitation treatments.

From 2008 to 2020, the mean age of stroke patients increased from 62.0 to 66.2 years. The proportion of ischemic stroke cases increased markedly from 47.3% to 74.5% while risk factors such as diabetes mellitus and hyperlipidemia showed increasing prevalence. Mechanical thrombectomy increased from 0% to 3.3%. Mean hospital stay decreased from 25.2 to 14.9 days, while in-hospital mortality declined from 5.9% to 3.7%. Rehabilitation consultations increased from 27.8% to 80.6%, occurring earlier during hospitalization. Rehabilitation therapy during hospitalization increased from 23.7% to 55.8%, and transfers to rehabilitation medicine rose from 12.8% to 19.1%. Home discharge increased from 34.8% to 60.0%.

Management of first-ever stroke patients in Korea improved substantially over 12 years, reflecting positive impacts of national quality initiatives and advancing stroke care.
