Use of highly active antiretroviral therapy in HIV-infected women: impact of HIV specialist care.

OBJECTIVES

To evaluate factors associated with use of HIV specialist care by women, and to determine whether medical indications for therapy validate lower rates of antiretroviral use in women not using HIV specialty care.

DESIGN

Cross-sectional analysis of the 1998 interview from the HIV Epidemiology Research Study (HERS) cohort.

METHODS

Data from 273 HIV-infected women in the HERS were analyzed by multiple logistic regression to calculate predictors of the use of HIV specialist care providers. Variables included study site, age, education, insurance status, income, substance abuse, depression, AIDS diagnosis, CD4 + lymphocyte count, and HIV-1 viral load. In addition, medical indications for therapy and medical advice to begin antiretroviral therapy were assessed.

RESULTS

Of 273 women, 222 (81%) used HIV specialists and 51 (19%) did not. Having health insurance, not being an injection drug user, and being depressed were predictive of using HIV specialist care (all p < or = .05). Although medical indications for therapy in the two groups were comparable, the rate of highly active antiretroviral therapy (HAART) use was significantly higher in women using HIV specialist care (27%) compared with those not using HIV specialists (7.8%). Women using HIV specialists received significantly more advice to begin antiretroviral therapy (ART) in the 6 months prior to the interview compared with those not using specialists (relative risk, 2.4; 95% CI = 1.3-4.6).

CONCLUSIONS

Having insurance, not being an injection drug user, and being depressed all increased the likelihood of women receiving HIV specialty care, which, in turn, increased the likelihood of receiving recommended therapies. The level of HAART use (23%) and any ART use (47%) in these HIV-infected women was disturbingly low. Despite comparable medical indications, fewer women obtaining care from other than HIV specialists received HAART. These data indicate substantial gaps in access to HIV specialist care and thereby to currently recommended antiretroviral treatment.
