title: HIV prevalence in a midwestern emergency department.
abstract: OBJECTIVE
  To determine the prevalence of human immunodeficiency virus (HIV) seropositivity of patients 15 years of age and older in our emergency department.
  
  
  METHODS
  HIV status was determined anonymously, and the seroprevalence rate was calculated. The 95% confidence intervals also were calculated. Twenty demographic and predictor categorical variable were cross-tabulated with HIV status to determine associations. Only gender and male homosexual preference were significantly associated by Fisher's exact test.
  
  
  METHODS
  Excess serum samples from 454 randomly selected patients 15 years of age and older who required venipuncture for their ED evaluation were included in the study.
  
  
  RESULTS
  Of the 454 serum specimens, six (1.32%) were positive for HIV. The 95% confidence interval was from 0.27% to 2.37%. All six positive patients were men. The only statistically significant risk factors associated with HIV seropositivity were male sex (P = .00112) and male homosexual preference (P = .0000).
  
  
  CONCLUSIONS
  HIV seropositivity occurs in 1.32% of our ED population over the age of 15 years. The only factors that correlate with HIV seropositivity are male homosexual preference and male sex.
