Abstract

Background: Little is known about the rates of Mycobacterium avium complex (MAC) and Pneumocystis carinii (PCP) prophylaxis adherence to guidelines and how they have changed after introduction of effective antiretroviral therapy. Objective: To determine rates of primary prophylaxis for MAC and PCP and to evaluate the influence of sociodemographic characteristics, region, and provider experience. Design: National probability sample cohort of HIV patients in care. Setting: One hundred sixty HIV health care providers. Patients: A total of 2864 patients interviewed in 1996 to 1997 (68% response) and 2267 follow-up interviews, representing 65% of surviving sampled patients (median follow-up, 15.1 months). Measurements: Use of prophylactic drugs, most recent CD4 count, sociodemographics, and regional and total HIV patients/providers. Results: Of patients eligible for primary MAC prophylaxis (most recent CD4 count <50/mm3), 41% at baseline and 40% at follow-up patients were treated. Of patients eligible for primary PCP prophylaxis (i.e., those with CD4 counts <200/mm3), 64% and 72% were treated, respectively. MAC prophylaxis at baseline was less likely in African American (adjusted odds ratio [OR], 35; 95% confidence interval ICI], 0.20-0.59), Hispanic (OR, 27; 95% CI, 0.08-0.94) and less-educated (OR, 0.61; 95% CI, 0.36-1.0) patients and more likely in U. S. geographic regions in the Pacific West (OR, 4.9; 95% CI, 1.0-23) and Midwest (OR, 6.4; 95% CI, 1.2-33) and in practices with more HIV patients. Conclusions: Most eligible patients did not receive MAC prophylaxis; PCP prophylaxis rates were better but still suboptimal. Our results support outreach efforts to African Americans, Hispanics, the less educated, and those in the northeastern United States and in practices with fewer HIV patients.
