There is growing concern about access to HIV/AIDS care among injection drug users (IDUs). We examined rates of CD4 cell count monitoring and correlates among HIV-infected IDUs.
This prospective observational cohort study of 460 community-recruited HIV-infected IDUs was situated in a Canadian city where all medical care is provided free of charge. Over a median follow-up period of 76 months, we evaluated factors associated with CD4 cell count monitoring through a linkage with a centralized CD4 registry.
