Korean Stroke Cohort for Functioning and Rehabilitation

Study Overview
=================
Brief Summary
-----------------
Korean Stroke Cohort for functioning and rehabilitation (KOSCO) 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. The main objectives of this study are to identify the factors that influence residual disability and long-term quality of life. The secondary objectives of this study are to determine the risk of mortality and recurrent vascular events in patients with acute first-ever stroke. 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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Korean modified Barthel Index | measurement for activities of daily living | 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Euro Quality of Life-5 Dimensions | measurement for quality of life | 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Functional Independence Measurement | measurement for activities of daily living | 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Korean Mini-Mental State Examination | measurement for cognitive function | 7 days, 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Korean Version of Frenchay Aphasia Screening Test | measurement for language function | 7 days, 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in modified Rankin Scale | Measurement for disability. Range of total score 0 to 6. 0 is no disability at all and 6 is death. Therefore, greater value means worse functional status | 7 days, 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in American Speech-Language-Hearing Association National Outcome Measurement System Swallowing Scale | Measurement for swallowing function. Range of scale is 0 to 7, and greater value means better function. For example, 7 means no swallowing difficulty at all. | 7 days, 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Geriatric depression scale-short form | measurement for depression. The scale is 0 to 15. 0 is normal whereas 15 indicates severe depression. | 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Fugl-Meyer Assessment | measurement for motor function | 7 days, 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset | 
| Change in Functional Ambulatory Category | measurement for gait function | 7 days, 3 months, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months, 72 months, 84 months, 96 months, 108 months after stroke onset |
