Although the overall prevalence of HAART has increased since the mid-1990s, demographic disparities in HAART receipt persist. Our results support attempts to increase access to care and frequency of outpatient visits for underutilizing groups as well as increased efforts to reduce persistent disparities in women, African Americans, and injection drug users (IDUs).

This study examines associations between HIV-positive individuals' receipt of ancillary services and their receipt of and retention in primary medical care. Ancillary care services examined include case management, mental health and substance abuse treatment/counseling, advocacy, respite and buddy/companion services, as well as food, housing, emergency financial assistance, and transportation. The selection criterion used was the receipt of care from January-June 1997 at selected facilities receiving funding under the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act, a federally funded safety net programme in the USA. The receipt of each ancillary service was associated with the receipt of any primary medical care from a safety net provider. All ancillary services were more strongly associated with primary care receipt than with retention in care or the mean number of primary care visits per year. Mental health and substance abuse treatment/counselling, client advocacy, respite care and buddy/companion services all had significant associations with all primary medical care measures. This is the first time in one study that the primary medical and ancillary services received by all clients at safety net-funded providers from multiple cities and states have been examined. All types of safety net providers, from the largest medical centre to the smallest community-based organization, are represented in this study. The patterns seen here are similar to the findings from the other, geographically more restricted, studies reported on in this volume.
