Assessment of Home-Time After Acute Ischemic Stroke in Medicare Beneficiaries.

Journal Article (Journal Article)

BACKGROUND AND PURPOSE: Stroke survivors have identified home-time as a meaningful outcome. We evaluated home-time as a patient-centered outcome in Medicare beneficiaries with ischemic stroke in comparison with modified Rankin Scale (mRS) score at 90 days and at 1 year post event. METHODS: Patients enrolled in Get With The Guidelines-Stroke (GWTG-Stroke) and Adherence Evaluation After Ischemic Stroke-Longitudinal (AVAIL) registries were linked to Medicare claims to ascertain home-time, defined as time spent alive and out of a hospital, inpatient rehabilitation, or skilled nursing facilities, at 90 days and at 1 year after admission. The correlation of home-time with mRS at 90 days and at 1 year was evaluated by Pearson correlation coefficients, and the ability of home-time to discriminate mRS (0-2) was assessed by c-index. RESULTS: There were 815 patients with ischemic stroke (age median, 76 years [interquartile range {IQR}, 70-82]; 46% women; National Institutes of Health Stroke Scale median, 4 [IQR, 2-7]) from 88 hospitals. The 90-day and 1-year median home-times were 79 (IQR, 52-86) days and 349 (IQR, 303-360) days and median mRS were 2 (IQR, 1-4) and 2 (IQR, 1-4). Greater home-time within 90 days was significantly correlated with lower 90-day mRS (Pearson correlation coefficient, -0.731; P<0.0001) and showed strong ability to discriminate functional independence with mRS 0 to 2 (c-index, 0.837). Similar findings were observed at 1 year. CONCLUSIONS: In a population of older patients with ischemic stroke, home-time was readily available from administrative data and associated with mRS at 90 days and 1 year. Home-time represents a novel, easily measured, patient-centered, outcome measure for an episode of stroke care.
