Study summary

Korean Stroke Cohort for functioning and rehabilitation (KOSCO)-II is a large, multi-centre prospective cohort study for all acute first-ever stroke patients admitted to participating hospitals in nine distinct areas of Korea. This study is designed as a 10-year, longitudinal follow-up investigating the residual disabilities, activity limitations, and quality of life issues arising in patients suffering from first-ever stroke as previous similar stroke cohort with KOSCO. The main objectives of this study are to identify and compare the factors that influence residual disability and long-term quality of life in first-ever acute stroke patients with KOSCO. The secondary objectives of this study are to determine and compare the risk of mortality and recurrent vascular events in first-ever acute stroke patients with KOSCO. Investigators will investigate longitudinal health behaviors and patterns of healthcare utilization, including stroke rehabilitation care. Investigators will also investigate the long-term health status, mood, and quality of life in stroke patient caregivers. In addition, investigators will identify baseline and ongoing characteristics that are associated with secondary outcomes.
