Factors associated with use of HIV primary care among persons recently diagnosed with HIV: examination of variables from the behavioural model of health-care utilization.

The delay between testing positive for human immunodeficiency virus (HIV) and entering medical care can be better understood by identifying variables associated with use of HIV primary care among persons recently diagnosed with the virus. We report findings from 270 HIV-positive persons enrolled in the Antiretroviral Treatment Access Study (ARTAS). 74% had not seen an HIV care provider before enrollment; 26% had one prior visit only. Based on Andersen's behavioural model of health care utilization, several variables reflecting demographic, healthcare, illness, behavioural, and psychosocial dimensions were assessed and used to predict the likelihood that participants had seen an HIV care provider six months after enrollment. Overall, 69% had seen an HIV care provider by six months. In multivariate analysis, the likelihood of seeing a provider was significantly (p<.05) higher among men, Hispanics (vs. non-Hispanic Blacks), those with higher education, those who did not use injection drugs, those with three or more HIV-related symptoms, those with public health insurance (vs. no insurance), and those who received short-term case management (vs. passive referral). The findings support several conceptual categories of Andersen's behavioural model of health services utilization as applied to the use of HIV medical care among persons recently diagnosed with HIV.
