Hospitalized HIV-Infected Patients in the HAART Era: A View from the Inner City

Abstract

To evaluate hospitalizations of HIV-infected patients in the highly active antiretroviral therapy (HAART) era, we analyzed 2736 admissions of 1562 HIV-infected patients to Cook County Hospital from September 20, 1999 to July 10, 2002. Patients were predominantly African American (81%), male (72%), and active substance abusers (74%). Only 48% of patients with a prior HIV diagnosis were taking HAART and 37% of them had a viral load less than 1000 copies per milliliter. Patients on protease inhibitor (PI)-sparing regimens more frequently achieved a viral load less than 1000 copies per milliliter than those on a PI-containing regimens (41% vs. 34% p = 0.036). For patients with CD4 cell counts less than 200 cells per milliliter, those not taking HAART were more likely African American (83% vs. 76%, p< 0.031), homeless (13% vs. 5%, p < 0.001), active substance abusers (79% vs. 65%, p < 0.001), female (28% vs. 22%, p = 0.001), new to the hospital system (19% vs. 6%, p< 0.001), or not recently seen in the outpatient clinic (42% vs. 17%, p < 0.001). In our population, active substance abuse was prevalent and only a minority of patients was taking HAART. Women were receiving HAART less often, independent of race and substance abuse. Aggressive programs are needed in high-risk populations to address substance abuse issues and to improve patient use of HAART.
