About 25% of HIV infected people do not know that they are infected. These people lack medical care that could prolong their lives and access to counseling services that could prevent further spread of HIV. With so many people unaware of their HIV status, there is a clear need for more readily available HIV counseling, testing, and referral services throughout the United States. The Centers for Disease Control and Prevention (CDC) recommends routine HIV testing in U.S. hospitals in which HIV infected patients make up at least 1% of the total patient population for that hospital. However, routine HIV testing in such hospitals is rarely carried out, which might be because the CDC has not specified who should perform routine HIV testing. The purpose of this study is to compare the effectiveness of two different approaches to providing routine HIV counseling, testing, and referral services in an urban hospital emergency department setting. One approach will be led by an HIV counselor, and the other approach will be led by an emergency department staff member. For both approaches, the study will evaluate to what extent patients accept HIV testing, how well follow-up care is established, and the cost-effectiveness of the approach.

Participants in this study will include adults who visit Brigham and Women's Hospital emergency department in Boston, Massachusetts. Participants will be randomly assigned to oral vs. fingerstick HIV testing by a designated HIV counselor and to fill out a questionnaire while waiting in the emergency room. The questionnaire will be anonymous. Participants will then be offered a rapid HIV test. Test results will be available in about 20 minutes and will be provided to participants by either their assigned HIV counselor. Participants who test positive for HIV will be offered a more definitive blood test to confirm HIV infection. The blood test results will be available 2 weeks from testing, and participants must return to the hospital to get their test results. Participants who test positive for HIV will be offered counseling support and referral services by either their assigned HIV counselor or emergency department staff member. Follow-up care appointments will also be initiated at this time. For participants who test positive for HIV, the study will last about 6 months. There will be no follow-up visits for participants who do not test positive for HIV during their emergency room visit.
