Objectives: To assess the ability of gait speed alone and a three-item lower extremity performance battery to predict 12-month rates of hospitalization, decline in health, and decline in function in primary care settings serving older adults.
Design: Prospective cohort study.
Setting: Primary care programs of a Medicare health maintenance organization (HMO) and Veterans Affairs (VA) system.
Background And Purpose: This study evaluated assessments of physical functioning and social functioning using the Stroke Impact Scale (SIS) and Short Form-36 (SF-36) to characterize health-related quality of life for patients after stroke.
Methods: The SIS and SF-36 were administered to 278 stroke subjects approximately 90 days after stroke. The SIS-16 and SF-36 Physical Functioning (PF) domain characterize physical function, whereas the SIS Participation and SF-36 Social Functioning (SF) domains characterize social function.
Background And Purpose: The purposes of this study were to compare proxy-patient responses on each domain of the Stroke Impact Scale (SIS) and the SIS-16, estimate the bias, and evaluate the validity of proxy scores.
Methods: Two hundred eighty-seven patient and proxy pairs from the Kansas City Stroke Registry participated in the study. All patients were assessed in their home or nursing facility between 90 and 120 days after stroke with the use of the modified Rankin Scale Motricity Index (strength), Barthel Index (activities of daily living), Lawton assessment (instrumental activities of daily living), Folstein Mini-Mental State Examination (cognition), and the SIS.
Background And Purpose: The purpose of this study was to compare disability and quality of life as measured by the Stroke Impact Scale (SIS) of stroke patients deemed recovered (Barthel Index > or =95) with 2 stroke-free populations of community-dwelling elderly.
Methods: Eighty-one stroke patients who participated in the Kansas City Stroke Registry and achieved a Barthel Index of > or =95 at 3 months after stroke and 246 stroke-free subjects enrolled in the Community Elders Study were enrolled in this study. The Community Elders Study group was further divided into 2 groups, those recruited from the Department of Veterans Affairs Health System (VA) and a those from a local health maintenance organization (HMO).
