Abstract

Study objective: To determine the prevalence of and risk factors associated with unrecognized HIV-1 infection among medical patients presenting to an inner-city emergency department. Methods: We conducted anonymous HIV-1 testing in subjects interviewed for risk behaviors and knowledge of HIV status at an inner-city ED in the Bronx, New York. Our subjects were consecutive adult medical patients in noncritical condition (N=1,744) who were evaluated by three physicians providing primary emergency care. Each patient was given a structured interview for demographic characteristics, risk behaviors, and knowledge of HIV status. Excess serum, drawn for clinical purposes, was linked without identifiers to responses and tested for antibodies to HIV-1. In subjects who denied HIV infection, we tested associations with seropositivity using univariate analyses and logistic-regression techniques (multivariate). Results: Of the 1,744 patients interviewed, 656 (37.6%) reported HIV risk behaviors. Of 970 tested for HIV-1 antibodies, 125 (12.9%) were seropositive. The prevalence of HIV- 1 infection among those who denied known infection was 4.0% (35 of 875). In the multivariate model, independent predictors of unrecognized HIV-1 infection were age 35 to 44 years, crack cocaine use, history of syphilis, and ED diagnosis of an infection not necessarily related to HIV infection. Unrecognized HIV-1 infection was more likely among patients admitted to the hospital, but 21 of the 35 with unrecognized infection (60%) were not admitted and in 9 (25.7%) no risk factors were identified. Conclusion: Mere than one third of patients who visited one inner-city ED acknowledged HIV risk behaviors. One quarter of patients with unrecognized HIV-1 infection reported no identifiable risk factors. Easily accessible HIV counseling and testing should be considered in EDs in areas serving persons at risk for HIV infection.
