Objective We determine the feasibility and yield of universal opt-out HIV screening among adolescents and adults in a southeastern emergency department (ED) serving a semiurban-semirural population. Methods Individuals aged 13 to 64 years who visited the ED during specified hours received the OraQuick rapid HIV test (administered by trained counselors) if they did not opt out. Western blot was used to confirm reactive results. Patients were excluded if they had a history of HIV, had been tested within the past year, were physically or mentally incapacitated, did not understand their right to opt out, or did not speak English or Spanish. Basic demographic information was analyzed by using standard descriptive statistics. Measures of diagnostic test performance were calculated for all valid tests. Results From March 2008 through August 2009, 91% (n=8,493) of eligible patients accepted testing, and results were valid. Of 41 reactive results, 35 were confirmed HIV positive, 2 were indeterminate by Western blot, and 4 were false positive. Blacks accounted for the largest percentage (0.65%) of newly detected infections, and the percentage among black men (1%) was more than twice the percentage among black women (0.42%). Rapid-test specificity was estimated at 99.95% (95% confidence interval 99.88% to 99.98%). Nearly 75% of patients confirmed as HIV positive kept their first HIV clinic appointment. Conclusion High rates of acceptance of testing in an ED and linkage to HIV care for adolescents and adults with newly detected infection can be achieved by using opt-out testing and trained HIV counselors.
