FACTORS ASSOCIATED WITH INITIATION OF PRIMARY MEDICAL-CARE FOR HIV-INFECTED PERSONS

PURPOSE: To examine the degree of immune dysfunction of human immunodeficiency virus (HIV)-infected patients at the time of presentation and to identify factors associated with early and late initial primary medical care for HIV infection as measured by CD4+ lymphocyte count. PATIENTS AND METHODS: Two hundred fifty-one consecutive outpatients without prior primary care for HIV infection were assessed at a municipal hospital HIV intake clinic (derivation group). Sociodemographic and clinical variables were examined for their association with CD4+ cell count on presentation in bivariate and stepwise linear regression analyses. Variables of interest were examined in 123 similar patients at a second site to assess the generalizability of our findings (validation group). RESULTS: In the derivation group, 30% of patients presented for initial primary care with CD4+ cell counts less than 200/mm(3), 51% had counts from 201/mm(3) to 500/mm(3), and only 19% had counts greater than 500/mm(3). Twenty-seven percent of patients had delayed seeking medical care for longer than 1 year and 12%, for more than 2 years after an initial positive HIV serologic evaluation. Three variables were significant and independent predictors of CD4+ cell count on presentation: Haitian ethnicity (P = 0.05) and HIV-related symptoms (P = 0.005) were associated with lower CD4+ cell counts; and female sex (P = 0.009) was associated with higher CD4+ cell counts. With HIV-related symptoms excluded from the model, a history of cocaine use was also a significant predictor for higher CD4+ cell count (P = 0.02). In the validation group, which included few Haitians, results for female sex and HIV-related symptoms showed a similar association. CONCLUSIONS: Most HIV-infected patients presented for primary care with advanced immune dysfunction. A substantial percentage of patients waited over a year to initiate medical care after testing positive for HIV. Haitian patients presented later for primary HIV care as measured by CD4+ cell count. Women presented with significantly higher CD4+ cell counts than did men. Since few characteristics examined could clearly identify the majority of late-presenting HIV-infected patients, improved general and targeted efforts are needed to link all HIV-infected people with primary medical care before the development of advanced disease.
