Abstract TMP47: Impact of Medicare Reform on Inpatient Rehabilitation Facility Access for Hemorrhagic Stroke Patients

Abstract

Introduction: There is growing evidence that ICH patients make larger & faster recovery gains compared to ischemic stroke patients. Inpatient rehabilitation facility (IRF) care can significantly facilitate improvement. In 2010, changes to IRF admission criteria potentially restricted access. We hypothesize the Centers for Medicare and Medicaid Services (CMS) 2010 IRF Prospective Payment System Rule decreased IRF access & increased skilled nursing facility (SNF) utilization in ICH patients. Methods: The proportion of ICH survivors discharged to IRF, SNF or home was estimated using GWTG-Stroke data between 1/1/2008 & 12/31/2015 (n=265,444). Two binary hierarchical models determined the association between the 1/1/2010 CMS admission criteria change for IRFs and discharge setting, adjusting for patient & hospital characteristics. Subgroup analyses evaluated the effects of age, region & hospital type. Sensitivity analyses used complete NIHSS data (≈49%). Results: The prevalence of the 3 discharge destinations changed significantly over time (CMH row-mean-score P<0.0001; Figure 1). IRF rehab odds decreased and SNF rehab odds increased for ICH patients compared to home after the CMS 2010 IRF PPS Rule (Figure 2a & 2b). Decreased IRF rehab odds were found in patients age<65, Western US location or at non-teaching hospitals (Figure 2a). Increased SNF rehab odds were found in patients age≥65, Midwest location or at teaching hospitals (Figure 2b). Conclusions: IRF Rehab odds decreased and SNF rehab odds increased during the time period after CMS 2010 IRF PPS Rule implementation in ICH patients. The impact of such legislative changes on patient outcomes warrants further study.
