title: Correlates of health care utilization among HIV-seropositive injection drug users.
abstract: This study sought to identify correlates of poor health care utilization among HIV-positive injection drug users (IDUs) using Andersen's behavioural health model. We used baseline data from INSPIRE, a study of HIV-positive IDUs (n=1161) to identify predisposing, enabling, and need factors related to poor utilization (defined as fewer than two outpatient visits in the past six months, or identification of emergency room (ER) as the usual place for care). Using bivariate and multivariate models, we found a number of enabling factors that could facilitate the use of health care services such as having health insurance, having seen a case manager, and better engagement with health care providers. These enabling factors could be modified through interventions targeting HIV-positive IDUs. In addition, health insurance and case management appear to be important factors to address because they contributed in making other factors (e.g. lower education, lack of stable housing) non-significant barriers to outpatient care utilization. In the future, these findings may be used to inform the development of interventions that maximize use of scarce HIV resources and improve health care utilization among HIV-positive IDUs.
