title: Access and use of medications in HIV disease.
abstract: OBJECTIVE
  To examine if measures of access to medical care are associated with outpatient use of antiretroviral and Pneumocystis carinii pneumonia (PCP) medications among a cohort of individuals with HIV disease.
  
  
  METHODS
  Adults who participated in a series of up to six interviews as part of the AIDS Costs and Services Utilization Survey (ACSUS). ACSUS, a panel survey of persons with HIV disease, was undertaken from 1991 through 1992.
  
  
  METHODS
  The Andersen Behavioral Model of Health Services Use provided the conceptual framework for the study. Logistic regression analyses with generalized estimating equations were conducted to determine the effects of predisposing, enabling, and need-for-care factors on the odds of antiretroviral or PCP medication use. The analytic sample consisted of 1,586 respondents whose 7,652 interviews provided the data.
  
  
  RESULTS
  The multivariate analysis showed that being female (OR = 0.76; 95% C.I. = 0.60-0.95), ages 15 to 24 years (OR = 0.64; 95% C.I. = 0.44-0.92), and having a hospitalization (OR = 0.73; 95% C.I. = 0.63-0.84) were associated with lower odds of using antiretrovirals. African American race (OR = 1.30; 95% C.I. = 1.04-1.62), having both public and private insurance (OR = 2.11; 95% C.I. = 1.47-3.03), attending counseling (OR = 1.17; 95% C.I. = 1.02-1.34), having a usual source of care (OR = 1.70; 95% C.I. = 1.38-2.11), and clinical trials participation (OR = 1.52; 95% C.I. = 1.23-1.87) were associated with a higher odds of use. Similar results were obtained for analyses of PCP medication use.
  
  
  CONCLUSIONS
  Sociodemographic differences exist in access and use of prescription drugs within the ACSUS cohort. The results suggest that women and those ages 15 to 24 years have poor access to some medications that improve survival in HIV disease.
