Timing of initiation of rehabilitation after stroke.

UNLABELLED: Maulden SA, Gassaway J, Horn SD, Smout RJ, DeJong G. Timing of initiation of rehabilitation after stroke.
OBJECTIVE: To study associations between days from stroke symptom onset to rehabilitation admission and rehabilitation outcomes, controlling for a variety of confounding variables.
DESIGN: Observational cohort study of 200 consecutive post-stroke rehabilitation patients in each of 6 inpatient rehabilitation facilities.
SETTING: Six U.S. inpatient rehabilitation hospitals. PARTICIPANTS: Patients (N=969) with moderate or severe strokes who had days from stroke symptom onset to rehabilitation admission recorded in their medical records.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Discharge total FIM, discharge motor FIM, discharge activities of daily living (ADL) FIM, and discharge mobility FIM scores, as well as rehabilitation length of stay (LOS).
RESULTS: Fewer days from stroke symptom onset to rehabilitation admission was associated significantly with better functional outcomes: higher total, motor, mobility, and ADL discharge FIM scores, controlling for confounding variables. For severely impaired patients with stroke in case-mix groups (CMGs) 108-114, the relation was strongest, with F statistics greater than 24.1 for each functional outcome. For patients with moderately severe stroke in CMGs 104-107, fewer days from stroke symptom onset to rehabilitation admission was associated significantly with shorter rehabilitation LOS.
CONCLUSIONS: Fewer days from stroke symptom onset to rehabilitation admission is associated with better functional outcomes at discharge and shorter LOS.
