Introduction:
Several AHA Guidelines recommend inpatient rehabilitation facility (IRF) care to enhance post-stroke recovery. We evaluated the IRF treatment effect on modified Rankin scale (mRS) score change at 90 days in ischemic stroke (IS) patients.
Methods:
Using prospectively collected data from Get With the Guidelines-Stroke, the Uniformed Data System for Medical Rehabilitation registry and the electronic medical record, we identified IS patients with discharge disposition of home or IRF between 1/1/2018-12/31/2020. Sociodemographics, clinical variables and IS treatment rates were summarized. IRF outcomes, including length of stay (LOS), improvement in mobility and self-care scores and discharge disposition were compared in thrombectomy vs no thrombectomy groups. mRS at IRF discharge was calculated with a Cronbach interrater score of 0.88; shift analyses of mRS at hospital discharge and 90 days were completed for IS patients in the Home and IRF care groups.
Results:
Among 738 patients, 499 went home, 239 went to IRF. IRF patients were more likely to have Medicare insurance (49.2 vs 28.9%), undergo thrombectomy (16.3 vs 4.6%) have increased LOS (12.7 vs 4.8 days) and stroke severity (mean NIHSS 7.8 vs 4.8; mean mRS 3.1 vs 1.7) compared to Home (Table 1). At IRF, 39 patients previously underwent thrombectomy, 200 did not. Both groups had a IRF LOS >14 days and considerable recovery in the self-care and mobility domains (Table 2). Shift analysis of mRS at hospital discharge compared to 90 days yielded significant improvements in mRS of 0-2 and lower mortality in the IRF group compared to home group (Figure).
Conclusion:
In ischemic stroke patients with higher disease severity, IRF treatment is a catalyst for improved functional recovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
