ObjectiveTo investigate the effects of facility-level factors on 30-day unplanned risk-adjusted hospital readmission after discharge from inpatient rehabilitation facilities (IRFs).DesignStudy using 100% Medicare claims data, covering 269,306 discharges from 1094 IRFs between October 2010 and September 2011.SettingIRFs with at least 30 discharges.ParticipantsA total number of 1094 IRFs (N=269,306) serving Medicare fee-for-service beneficiaries.InterventionsNot applicable.Main Outcome MeasuresRisk-standardized readmission rate (RSRR) for 30-day hospital readmission.ResultsProfit status was the only provider-level IRF characteristic significantly associated with unplanned readmissions. For-profit IRFs had a significantly higher RSRR (13.26±0.51) than did nonprofit IRFs (13.15±0.47) (P<.001). After controlling for all other facility characteristics (except for accreditation status because of its collinearity with facility type), for-profit IRFs had a 0.1% point higher RSRR than did nonprofit IRFs, and census region was the only significant region-level characteristic, with the South showing the highest RSRR of all regions (type III test, P=.005 for both).ConclusionsOur findings support the inclusion of profit status on the IRF Compare website (a platform including IRF comparators to indicate quality of services). For-profit IRFs had a higher RSRR than did nonprofit IRFs for Medicare beneficiaries. The South had a higher RSRR than did other regions. The RSRR difference between for-profit and nonprofit IRFs could be due to the combined effects of organizational and regional factors.
