Objective: We explored the effect of patient and provider factors on the type of antiretroviral regimen among women receiving therapy. Patients: Five hundred ninety-five New York State nonpregnant HIV+ women with full Medicaid eligibility and at least 1 month of a prescribed antiretroviral regimen in federal fiscal years (FFY) 1997-1998 and intervals in FFY 1997-1998, who had delivered a liveborn baby within 5 years. Measurements: From pharmacy claims in 4 6-month intervals in FFY 1997-1998, data were extracted on (1) an acceptable ≥2 antiretroviral combination regimen per expert guidelines; and (2) a highly active regimen, including a protease inhibitor or nonnucleoside analog (highly active antiretroviral therapy [HAART]). Results: Of 1514 woman-6-month intervals with filled antiretroviral prescriptions, 82% had an acceptable regimen, and of 1246 woman-6-month intervals on acceptable antiretroviral therapy, half demonstrated the use of HAART. Adjusted odds ratios (AORs) of acceptable antiretroviral therapy were higher (p < .05) for HIV specialty care (AOR = 1.71 for one or two visits; AOR = 2.10 for 3+ visits) or HIV clinical trials site care (AOR = 1.43; 95% confidence interval [CI]: 1.01, 2.04). Among women on acceptable antiretroviral regimens, those aged older than 25 years (AOR = 1.69; CI: 1.13, 2.53) or who were high school graduates (AOR = 1.50; CI: 1.09, 2.06) had higher odds of HAART. Mcthadone-treated women had twofold and nearly threefold higher AORs of acceptable antiretroviral regimens and HAART, respectively, than current drug users. Conclusion: Provider HIV expertise is associated with receipt of an acceptable antiretroviral regimen in women, although receipt of HAART is affected more by age, education, and current drug abuse. Methadone treatment seems to improve access to acceptable antiretroviral regimens as well as to HAART.
