Intro: A person with stroke has improved outcomes with post-acute care in an inpatient rehabilitation facility (IRF) or at home compared to those who are discharged to a skilled nursing facility (SNF). However, this research was conducted in an era before acute stroke treatment was fully developed and implemented. In this analysis of a recently completed acute intervention trial, we hypothesize that subjects with similar severity of strokes will have better 90 day outcomes if they are discharged to a IRF or home compared to a SNF. Methods: Using the data from SENTIS, a prospective, multi-center single-blind, randomized trial of use of NeuroFlo technology compared to standard acute stroke therapy, patient demographics, day 4 National Institutes of Health Stroke Scores (NIHSS), and 90 day modified Rankin scores (mRS) was obtained. Severity of stroke was classfied in 3 groups based on NIHSS: less than 8, 8-13, 14+. Disposition following acute hospital care was classified as home, IRF and SNF. A favorable outcome was defined as 90 day mRS ≤ 2. For each stroke severity class, the effect of each disposition on a favorable outcome was calculated. Results: A total of 292 patients were analyzed with a mean age of 65±14 with presenting NIHSS of < 8 in 94/297(31.6%), NIHSS 8-13 in 118/297(39.7%) and 14+ in 85/297(28.6%) of patients. Regardless of day 4 NIHSS, only 2 out of 28 (7.1%) patients who were discharged to SNF achieved a 90 day mRS ≤2, compared to 60/153 (39.2%) in the IRF group (OR 8.02 95%CI[1.83-35.11], p=0.0057). Table 1 shows the distribution of outcomes by post-acute care disposition and day 4 NIHSS. Conclusions: The day 4 NIHSS had an inverse relationship with the likelihood of a favorable outome. Subjects who were discharged home or to an IRF were significantly more likely to have a favorable outcome compared to those who were discharged to a SNF. This analysis supports prior data stating that discharge disposition plays a role in determining outcomes.
