Abstract WP138: Effect of Duration Between Stroke Onset and Admission to Inpatient Rehabilitation Facilities on Improvement in Activities of Daily Living During Hospitalization

Abstract

Objective: This study aimed to determine whether early admission of stroke patients to inpatient rehabilitation facilities (IRFs) resulted in improvement in motor function during hospitalization. Methods: Data were extracted from the Japan association of rehabilitation database for 2,177 patients admitted to IRFs at 32 centers. Items surveyed were age; sex; stroke type; length of stay; period from onset to IRF admission (≤7, 8–14, or 15–60 days); motor functional independence measure (mFIM) and cognitive FIM (cFIM) at admission and discharge; and modified Rankin Scale (mRS) score before onset, at admission, and at discharge. In addition, the difference between mFIM at admission and at discharge (mFIM gain) were calculated. For comparative analysis, we stratified patients into mildly, moderately, and severely impaired groups if their mRS scores at admission were 0–2, 3, and 4–5, respectively. We used multiple regression analysis to examine the factors affecting ADL at discharge. Results: Mildly impaired patients admitted within 7 days of onset had a higher mFIM score and mFIM gain (estimate=4.75, p=0.032) than those admitted 15–60 days after onset. Meanwhile in moderately impaired patients, no correlation was found between the length of time from onset to admission, and mFIM and mFIM gain. Severely impaired patients admitted within 7 days of onset had a higher mFIM score and mFIM gain (estimate=9.07, p=0.032) than those admitted 15–60 days after onset. Conclusion: Mildly and severely impaired stroke patients experience greater improvement in ADL, if admitted to an IRF within 7 days after stroke onset.
