Brief risk-reduction counseling at the time of a rapid human immunodeficiency virus (HIV) testing was not effective in reducing new sexually transmitted infections (STIs) during the subsequent six months among persons at risk for HIV. Dr. Lisa R. Metsch, researcher at Columbia University Mailman School of Public Health, and colleagues conducted the trial to assess the effectiveness of counseling in reducing STI incidence. Participants were from nine STI clinics affiliated with the NIDA Drug Abuse Treatment Clinical Trials Network in Columbia, SC, Jacksonville, FL, Los Angeles, CA, Miami, FL, San Francisco, CA, Pittsburgh, PA, Portland, OR, Seattle, WA, and Washington, DC. Findings are online in the October 23rd issue of JAMA.
