Ante- and postpartum substance abuse treatment and antiretroviral therapy among HIV-infected women on Medicaid.
OBJECTIVE
To examine temporal associations between obstetrics/gynecology (ob/gyn) care, substance abuse treatment (SAT), and antiretroviral therapy (ART) during and after pregnancy among HIV-infected women on Medicaid.


METHODS
We identified 345 women, representing 378 deliveries, from merged New Jersey AIDS/HIV surveillance data and paid Medicaid claims data between 1992 and 1998. T-tests were used to analyze person-level differences in service use before and after delivery. Data were converted to person-months to predict SAT and receipt of ART in multivariate regressions that corrected for correlations among repeated observations.


RESULTS
Compared to antepartum months there were significant reductions in ART and ob/gyn care in postpartum months and a significant increase in substance abuse. Multivariate analyses showed that compared to other months, women were more likely to obtain SAT during the postpartum period (odds ratio [OR] 1.51, 95% confidence interval [CI], 1.31-1.74); conversely, women were more likely to receive ART in the antepartum period (OR 1.77, 95% CI, 1.43-2.17). Ob/gyn care predicted ART and SAT, regardless of the timing of care relative to delivery. African American women were least likely to receive SAT and ART.


CONCLUSIONS
Our findings underscore that ob/gyn providers have a central position in pathways to care for a vulnerable population of women with multiple health care needs and that patterns of ART use and SAT shift markedly during the months before and after delivery. However, receipt of ob/gyn care during these months is not associated with the changes, suggesting that ob/gyn providers may have untapped opportunities during the ante- and postpartum months to educate women with HIV/AIDS about the importance of consistent use of ART and to provide SAT referrals as needed. These results may have implications for policy makers interested in promoting adherence to ART and decreasing substance abuse among women with HIV/AIDS.
