Rapid Home HIV Testing: A Crucial Tool for Preventing HIV Exposure Among High-Risk MSM

This study evaluates the use of rapid HIV home testing (HT) among high-risk men who have sex with men (MSM) for screening sexual partners to prevent HIV exposure. Conducted among a diverse group of 27 participants, the research explores both hypothetical interest and actual utilization of HT before receptive anal intercourse. Results indicated high acceptability and effectiveness, with many partners disclosing their HIV status and 10 testing positive. The findings support HT as a critical harm reduction strategy that can enhance awareness, promote safer sexual practices, and identify undetected HIV infections.

  1. USE OF A RAPID HIV HOME TEST TO SCREEN POTENTIAL SEXUAL PARTNERS PREVENTS HIV EXPOSURE IN A HIGH RISK SAMPLE OF MSM Alex Carballo-Diéguez, Ivan Balan, Timothy Frasca, Curtis Dolezal, Juan Valladares HIV Center for Clinical and Behavioral Studies, NYS Psychiatric Institute and Columbia University, New York, NY, USA This research was supported by a NIMH grant (R01-MH079692; PI, Alex Carballo-Diéguez, Ph.D.) and a NIMH center grant (P30-MH43520; PI: Anke A. Ehrhardt, Ph.D.).

  2. Study Design

  3. Study Design • Prior work on high risk MSM (bareback sex) • Study Question • Would high-risk MSM be interested in testing their partners prior to receptive anal intercourse as a harm-reduction approach?

  4. Study Design • Stage 1: Hypothetical use

  5. Study Design • Stage 2: Actual use • Sample • 27 men (33% African American, 19% Latino, 41% White, 7% other; age range, 18 to 58) • Methods • CASI & unassisted HIV rapid self-test at baseline • 16 test kits given to participants for use over 3 months • 24-hour hotline run by 2 senior clinical psychologists • Weekly reports on use through phone reporting system • In-depth interview at 3 month follow-up visit

  6. Results • Home Test Use Over 3-month Period • 124 partners were asked to use HT • 101 agreed • 23 refused • Partner resistance to HT was seen as a sign not to have UAI • Proposing HT use led 2 partners to disclose seropositivity • Mutual testing often took place • 10 tested individuals had positive results • 7 were prospective partners, 3 acquaintances • 6 were unaware of positive status • No UAI occurred when a partner was HIV-infected • Partners were verbally aggressive on 7 occasions (of 124) but no violence ensued.

  7. Conclusions • Rapid HIV Home Testing … • is highly acceptable among high-risk MSM • can identify previously undetected cases of HIV infection • can prevent potential HIV transmission • allows users to modify their sexual behavior to decrease their own risk of HIV infection • can increase frequency of HIV testing in high-risk MSM • may become an important harm reduction technology • can reach network members who do not access the healthcare system

  8. Conclusions
