From conventional to disruptive: upturning the HIV testing status quo among men who have sex with men in Vietnam.

Abstract

Introduction HIV prevalence among men who have sex with men (MSM) in Vietnam is increasing, while annual HIV testing uptake has remained consistently low, posing a significant challenge to reaching the 90‐90‐90 goals. Barriers to MSM seeking HIV testing include concerns regarding confidentiality and lack of convenient testing options. Two new HIV testing strategies—HIV lay provider and HIV self‐testing (HIVST)—were piloted alongside intensive social media outreach to increase access to and uptake of HIV testing among MSM not actively engaged in services.MethodsWe measured the proportion of first‐time MSM HIV testers opting for HIV lay or self‐testing, and factors that were associated with first‐time testing, as part of a larger HIV lay and self‐testing study among key populations in Vietnam. We also assessed MSM satisfaction with HIV lay or self‐testing, and testing location and provider preferences. Finally, we calculated linkage to care cascade among MSM that were diagnosed and enrolled in anti‐retroviral therapy (ART) services.ResultsAmong MSM that sought HIV lay and self‐testing, 57.9% (n = 320) and 51.3% (n = 412) were first‐time testers respectively. In the final adjusted models, the odds of being a first‐time tester and opting for HIV lay testing were higher among MSM who were young, had lower levels of income and had never exchanged sex for money; for HIVST, the odds of being a first‐time HIV tester were higher among MSM that had attained lower levels of education. HIV lay and self‐testing resulted in higher detection of new HIV cases (6.8%) compared to conventional HIV testing among key populations (estimated at 1.6% in 2016), while MSM linked to testing through social media interventions presented with even higher HIV‐positivity (11%). Combined, 1655 HIV cases were diagnosed and more than 90% were registered for ART services.ConclusionsOur findings suggest that MSM‐delivered HIV testing and self‐testing, promoted through online or face‐to‐face interactions, offer important additions to MSM HIV testing services in Vietnam, and could significantly contribute to epidemic control by increasing HIV testing among harder‐to‐reach and higher‐risk MSM, effectively enrolling them in ART, and reducing onward transmission.
