Abstract
To assess whether better access to community-based outpatient medical services was associated with fewer HIV-related hospitalizations, we studied 217 patients hospitalized at seven southern California hospitals. During hospital admission, patients completed an interview that included one item about the reported difficulty or ease of access to community-based medical services prior to their first hospitalization for HIV-related illness. After discharge, medical records were abstracted for data on prior hospitalizations. CD4 counts, and illness severity. About one-half of patients reported that medical services were readily accessible. Medical records revealed that since the time of HIV infection 49% had two or more total hospitalizations (mean = 2. SD = 2). In multiple logistic regression analysis, better reported access to services was significantly associated with not having been hospitalized (vs. having been hospitalized) over the same time period (OR = 0.73, 95% CI = 0.55-0.97), controlling for CD4 count, illness severity, duration of diagnosed HIV infection, having a regular source of care, type of hospital care, insurance coverage, and other patient characteristics. Improving access to community-based medical services for ambulatory HIV-infected patients may help to avert costly hospital care. Prospective studies are needed to assess whether a causal relationship between greater community-based access and reduced hospitalizations exists and, if so, whether community-based services may be cost-effective substitutes for hospital HIV care.
