Crowdsourced partner services among men who have sex with men living with HIV: A pilot randomized controlled trial in China.

BACKGROUND:This study aimed to assess the acceptability, feasibility, and preliminary effectiveness of a crowdsourced HIV partner services (PS) intervention among men who have sex with men living with HIV (MLWH) in China. METHODS:A pilot two-arm randomized controlled trial (RCT) was conducted in three HIV testing clinics in China. The control arm received conventional HIV PS while the intervention arm received a crowdsourced intervention, including HIV self-testing kits for secondary distribution (HIVST-SD), digital education materials, and assisted PS. The intervention was developed through two-phase crowdsourcing events including an open call and a Designathon. The primary outcomes were measured by the 3-month follow-up rate (i.e., the proportion of participants who completed the follow-up survey to report HIV PS outcomes three months after enrollment) and the frequency of using intervention components (feasibility), index evaluation of intervention components (acceptability), and the proportion of partners getting HIV testing (preliminary effectiveness). RESULTS:The study enrolled 121 newly diagnosed MLWH between July 2021 and May 2022. The 3-month follow-up rates were 93% (75/81) and 83% (33/40) in the intervention and control arms, respectively. Crowdsourced intervention components demonstrated feasibility, with all indexes utilizing digital educational materials, 23 successfully using HIVST-SD, and six employing provider-referral to notify nine sexual partners. Acceptability was high, with HIVST-SD and digital educational materials rated 4·4 and 4.1 out of 5. The proportion of partners receiving HIV testing was 11% higher in the intervention arm than in the control arm (marginal significance with 95% CI = [-2%, 24%], 38% vs. 27%). CONCLUSION:The crowdsourced HIV PS intervention was acceptable and feasible, suggesting the potential to facilitate partner HIV testing among Chinese MLWH. Further implementation research is recommended to expand HIV PS among key populations in low- and middle-income countries.Clinical trial registration ID: NCT04971967 (Protocol ID: 19-0496).
