Background: National data from the mid-1990s demonstrated that many eligible patients did not receive highly active antiretroviral therapy (HAART) and that racial and gender disparities existed in HAART receipt. We examined whether demographic disparities in the use of HAART persist in 2001 and if outpatient care is associated with HAART utilization. Methods: Demographic, clinical, and pharmacy utilization data were collected from 10 US HIV primary care sites in the HIV Research Network (HIVRN). Using multivariate logistic regression, we examined demographic and clinical differences associated with receipt of HAART and the association of outpatient utilization with HAART. Results: In our cohort in 2001, 84% of patients received HAART and 66% had 4 or more outpatient visits during calendar year (CY) 2001. Of those with 2 or more CD4 counts below 350 cells/mm3 in 2001, 91% received HAART; 82% of those with 1 CD4 test result below 350 cells/mm3 received HAART; and 77% of those with no CD4 counts below 350 cells/mm3 received HAART. Adjusting for care site in multivariate analyses, age >40 years (adjusted odds ratio [AOR] = 1.13), male gender (AOR = 1.23), Medicaid coverage (AOR = 1.16), Medicare coverage (AOR = 1.73), having 1 or more CD4 counts less than 350 cells/mm3 (AOR = 1.33), and having 4 or more outpatient visits in a year (OR = 1.34) were significantly associated with an increased likelihood of HAART. African Americans (odds ratio [OR] = 0.84) and those with an injection drug use risk factor (OR = 0.86) were less likely to receive HAART. Conclusions: 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).

Background:Rapid changes in HIV epidemiology and antiretroviral therapy may have resulted in recent changes in patterns of healthcare utilization. Objective:The objective of this study was to examine sociodemographic and clinical correlates of inpatient and outpatient HIV-related health service utilization in a multistate sample of patients with HIV. Design:Demographic, clinical, and resource utilization data were collected from medical records for 2000, 2001, and 2002. Setting:This study was conducted at 11 U.S. HIV primary and specialty care sites in different geographic regions. Patients:In each year, HIV-positive patients with at least one CD4 count and any use of inpatient, outpatient, or emergency room services. Sample sizes were 13,392 in 2000, 15,211 in 2001, and 14,403 in 2002. Main Outcome Measures:Main outcome measures were number of hospital admissions, total days in hospital, and number of outpatient clinic/office visits per year. Inpatient and outpatient costs were estimated by applying unit costs to numbers of inpatient days and outpatient visits. Results:Mean numbers of admissions per person per year decreased from 2000 (0.40) to 2002 (0.35), but this difference was not significant in multivariate analyses. Hospitalization rates were significantly higher among patients with greater immunosuppression, women, blacks, patients who acquired HIV through drug use, those 50 years of age and over, and those with Medicaid or Medicare. Mean annual outpatient visits decreased significantly between 2000 and 2002, from 6.06 to 5.66 visits per person per year. Whites, Hispanics, those 30 years of age and over, those on highly active antiretroviral therapy (HAART), and those with Medicaid or Medicare had significantly higher outpatient utilization. Inpatient costs per patient per month (PPPM) were estimated to be

101 in 2002. Conclusion:Changes in utilization over this 3-year period, although statistically significant in some cases, were not substantial. Hospitalization rates remain relatively high among minority or disadvantaged groups, suggesting persistent disparities in care. Combined inpatient and outpatient costs for patients on HAART were not significantly lower than for patients not on HAART.

Background:The delivery of HIV healthcare historically has been expensive. The most recent national data regarding HIV healthcare costs were from 1996–1998. We provide updated estimates of expenditures for HIV management. Methods:We performed a cross-sectional review of medical records at 10 sites in the HIV Research Network, a consortium of high-volume HIV care providers across the United States. We assessed inpatient days, outpatient visits, and prescribed antiretroviral and opportunistic illness prophylaxis medications for 14 691 adult HIV-infected patients in primary HIV care in 2006. We estimated total care expenditures, stratified by the median CD4 cell count obtained in 2006 (≤50, 51–200, 201–350, 351–500, >500 cells/μl). Per-unit costs of care were based on Healthcare Cost and Utilization Project (HCUP) data for inpatient care, discounted average wholesale prices for medications, and Medicare physician fees for outpatient care. Results:Averaging over all CD4 strata, the mean annual total expenditures per person for HIV care in 2006 in three sites was US
