Randomized Controlled Trial Clinical Trial
Predictors of medical service utilization among individuals with co-occurring HIV infection and substance abuse disorders.
This study examined factors affecting medical service use among HIV-infected persons with a substance abuse disorder. The sample comprised 190 participants enrolled in a randomized trial of a case management intervention. Participants were interviewed about their backgrounds, housing status, income, alcohol and drug use problems, health status and depressive symptoms at study entry. ⋯ Homelessness was associated with higher utilization of emergency department and inpatient services; drug use severity was associated with higher inpatient and ambulatory care service use; and alcohol use severity was associated with greater use of emergency medical services. Homelessness and substance abuse exacerbate the health care needs of HIV-infected persons and result in increased use of emergency department and inpatient services. Interventions are needed that target HIV-infected persons with substance abuse disorders, particularly those that increase entry and retention in outpatient health care and thus decrease reliance on acute hospital-based services.
