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.

Outcome Measures

Primary Outcomes (10)

• 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
