Secondary Distribution of HIV Self-tests: an Innovative Strategy for Promoting Partner Testing and Reducing HIV Risk

The study will recruit HIV-negative adult women who had two or more sexual partners within the past four weeks in the Nyanza region of Kenya. Beach communities and female sex worker hotspots will be randomized to an intervention group or a control group. In intervention clusters, participants will receive multiple oral fluid-based HIV test kits over a period of up to 24 months, training on how to use the tests, and encouragement to offer tests to current and potential sexual partners with whom sex without condoms is likely. In the comparison clusters, participants will be given referral vouchers for clinic-based HIV testing over a period of up to 24-months and encouraged to distribute these vouchers to sexual partners. Data will be collected from study participants at baseline on demographic and socio-economic characteristics, self-reported sexual behavior, HIV testing history, intimate partner violence history, and mental health outcomes. Follow-up data collection will occur every 6 months. Each month, participants will be sent an invitation to participate in short mobile phone based text message surveys. HIV testing of participants will occur at baseline and at 6 monthly intervals. Based on their reported use of the HIV self-tests, participants will be invited for qualitative interviews to learn more about their interactions with partners with regard to the distribution of self-tests and referral vouchers. Participants will also be given information to distribute to some of their male partners so that those partners can contact study staff to participate in qualitative interviews that will inquired about their perceptions of self-tests. The study has 3 specific aims. Aim 1 will determine the intervention's effect on uptake of HIV testing and identification of HIV infection among participants' sexual partners, self-reported sexual behavior of participants with partners whose HIV status was HIV-positive or not known, and HIV incidence among participants. Aim 2 will use a mixed methods approach to assessing safety and perceptions of the intervention by participants and their sexual partners. Aim 3 will assess the cost-effectiveness of the intervention and obtain information necessary to inform scale-up of the intervention in Kenya and other countries.
