description: OBJECTIVES:: To assess the effect of two health systems approaches to distribute HIV self-tests on the number of female sex workers’ client and non-client sexual partners in a randomized controlled trial of HIV self-testing among female sex workers (FSW) in Zambia. DESIGN:: Cluster randomized controlled trial. METHODS:: Peer educators recruited 965 participants. Peer educator-participant groups were randomized 1:1:1 to one of three arms: 1) delivery of HIV self-tests directly from a peer educator, 2) free facility-based delivery of HIV-self tests in exchange for coupons, or 3) referral to standard HIV testing (standard of care). Participants in all three arms completed four peer educator intervention sessions, which included counseling and condom distribution. Participants were asked the average number of client partners they had per night at baseline, one and four months, and the number of non-client partners they had in the past 12 months (at baseline) and in the past month (at one month and four months). RESULTS:: At four months, participants reported significantly fewer clients per night in the delivery arm (mean difference -0.78 clients, 95% CI -1.28 to -0.28, P = 0.002) and the coupon arm (-0.71, 95% CI -1.21 to -0.21, P = 0.005) compared to standard-of-care. Similarly, they reported fewer non-client partners in the delivery (-3.19, 95% CI -5.18 to -1.21, P = 0.002) and in the coupon arm (-1.84, 95% CI -3.81 to 0.14, P = 0.07) arm compared to standard-of-care. CONCLUSIONS:: Expansion of HIV self-testing may have positive spillover effects on HIV prevention efforts among FSW in Zambia. TRIAL REGISTRATION:: ClinicalTrials.gov NCT02827240
