RESUMO
OBJECTIVE: To determine Inpatient Rehabilitation Facility (IRF) treatment effect on modified Rankin Scale (mRS) scores at 90 days in acute ischemic stroke (AIS) patients. MATERIALS AND METHODS: This prospective cross-sectional study included 738 AIS patients admitted 1/1/2018-12/31/2020 to a Comprehensive Stroke Center with a Stroke Rehabilitation program. We compared outcomes for patients who went directly home versus went to IRF at hospital discharge: (1) acute care length of stay (LOS), (2) National Institutes of Health Stroke Scale (NIHSS) score, (3) mRS score at hospital discharge and 90 days, (4) the proportion of mRS scores ≤ 2 from hospital discharge to 90 days. RESULTS: Among 738 patients, 499 went home, and 239 went to IRF. IRF patients were more likely to have increased acute LOS (10.7 vs 3.9 days; t-test, P<0.0001), increased mean NIHSS score (7.8 vs 4.8; t-test, P<0.0001) and higher median mRS score (3 vs 1, t-test, P<0.0001) compared to patients who went home. At 90 days, ischemic stroke patients who received IRF care were more likely to progress to a mRS ≤ 2 (18.7% increase) compared to patients discharged home from acute care (16.3% decrease). Home patients experienced a one-point decrease in mRS at 90 days compared to those who received IRF treatment (median mRS of 3 vs. 2, t-test, P<0.05). CONCLUSIONS: In ischemic stroke patients, IRF treatment increased the likelihood of achieving mRS ≤ 2 at 90 days indicating the ability to live independently, and decreased the likelihood of mRS decrease, compared with patients discharged directly home after acute stroke care.
