Characterization of inpatient rehabilitation outcomes among HIV/AIDS patients: a retrospective cohort study

ABSTRACT Survival time in HIV/AIDS patients has increased as a result of improved treatments, but many acquire functional impairments that may necessitate multidisciplinary medical rehabilitation. In the United States, inpatient rehabilitation facilities (IRF) provide this care, but outcomes are not well described in this population. We used the Uniform Data System for Medical Rehabilitation (UDSMR) database to describe 11,051 HIV/AIDS IRF patients; HIV/AIDS patients were grouped according to the following admission criteria: (1) HIV/AIDS as primary reason for admission (n = 225); (2) HIV/AIDS symptomatic comorbidity (n = 6569); and (3) HIV/AIDS asymptomatic comorbidity (n = 4257). We used standard descriptive statistics to summarize demographic, medical, rehabilitation, and discharge setting characteristics by group. When compared to patients with HIV/AIDS as a comorbidity, primary HIV/AIDS patients had worse outcomes. They made less functional change (25.1 versus 29.8 and 28.9, p < .001), went home less (73.8% versus 74.5% and 77.8%, p < .001) and to an acute care hospital more frequently (18.2% versus 13.9% and 10.1%, p < .001). These findings help to characterize the HIV/AIDS patient population who receive inpatient medical rehabilitation, which helps inform clinical care, and highlight the positive impact IRF care can make to minimize functional disability among chronic HIV/AIDS patients and possibly decrease costs of home health care.
