Peer-led HIV Self-testing Among Men in Two Ugandan Fishing Communities

Overview

The goal of this behavioral interventional study is to assess the feasibility and acceptability of a peer-led HIV self-testing intervention among men in two fishing communities along the shores of Lake Victoria in Uganda. The main objectives of the study are: a) to assess the feasibility of implementing a peer-led HIV self-testing intervention among men in a fishing community context; b) determine the uptake of HIV self-testing among men in the fishing communities, and c) determine linkage to and retention in HIV care among newly diagnosed HIV-positive men following peer-led HIV self-testing. Participants will: * Be administered a baseline questionnaire to assess prior HIV testing behaviors and willingness to self-test for HIV * Receive two HIV self-test kits, one for them and one for someone else that they prefer to give the kit, to determine HIV testing behaviors among men and their significant others * Be administered follow-up questionnaires at one (1), six (6) and 12 months post-baseline to determine linkage to and retention in HIV care among those testing HIV-positive, as well as linkage to appropriate HIV prevention services among those testing HIV-negative.

Background In this study, investigators propose to use a social network-based, peer-led HIV self-testing model to assess uptake of HIV testing, as well as linkage to appropriate HIV prevention, care and treatment services in two high HIV prevalence island districts with limited access to HIV and other health services. Primary aims 1. Compare approaches for peer-leader selection in two fishing communities in order to identify suitable peer-leader selection approaches for typical fishing communities. 2. Assess uptake of HIV testing services associated with peer-led HIV self-testing among men living in two high HIV prevalence fishing communities 3. Assess the effect of a peer-led HIV self-testing (HIVST) model in: (i) identifying previously undiagnosed HIV infections; (ii) improving linkage to HIV care among newly identified HIV-positive individuals; and (iii) improving retention in HIV care among linked HIV-positive individuals Study sites The intervention will be conducted in two different fishing communities (one in each district) located in two high HIV prevalence island districts of Buvuma and Kalangala, located in Lake Victoria, Uganda. Intervention Description The peer-led HIV self-testing intervention will include distribution of HIV self-test kits through trained male peer-leaders. Forty peer-leaders will be selected through community meetings held in each fishing community. The following sub-sections describe the key components of the intervention. 1. Training of selected peer-leaders and distribution of HIV self-test kits Selected peer-leaders will be trained in HIV self-testing processes and procedures for a period of three days after which they will be asked to nominate up to 20 male members (15+ years) from their social network. All the nominated social network members will be screened for eligibility and up to 400 eligible men will be enrolled into the study. Peer-leaders will receive the number of kits equal to the number of eligible members enrolled from their social network for up to 20 kits per peer-leader. Peer-leaders will receive a one-time facilitation allowance to facilitate their movement in the community during the process of distributing HIV self-test kits to members of their social network. As part of the distribution process, peer-leaders will be requested to demonstrate to their social network members how the HIV self-testing process is done, including how to obtain the oral swab, how to time the 20 minutes needed for the kit to show results, and how to read and interpret results. 2. Antiretroviral therapy initiation through health facility-coordinated mobile outreaches Given that fishing communities do not usually have health facilities within their proximity, many HIV-positive individuals tend to miss conventional HIV testing and linkage to HIV care services. To address this gap, investigators intend to work with mainland health facilities nearest to the targeted fishing communities to conduct health outreach sessions in which HIV testing and linkage to HIV will be provided as part of a multi-disease health promotional campaign. Study participants will be notified through their peer-leaders regarding when the health outreach sessions will be conducted and they will be requested to come and access free health services, including confirmatory HIV testing. Study participants who will be confirmed as HIV-positive will be provided with an initial dose of antiretroviral therapy (at the same outreach session) lasting until the next outreach session or until they are linked to an existing community client-led ART delivery (CCLAD) group, while those confirmed as HIV-negative will be linked to appropriate HIV prevention services including condom promotion and male circumcision services, as appropriate. 3. Peer-facilitated retention in HIV care Retention in HIV care is an ongoing challenge in HIV care and treatment programs. At the time of linkage to HIV care, the investigators will ask HIV-positive individuals if they have anyone within their close network that can act as their treatment buddy (including their peer-leader); someone who could help to pick their drugs at the planned outreach sessions in the event that they cannot do so, or provide them with psycho-social support as needed in order to help them continue to take their HIV treatment as recommended. If they agree, social network members will be asked if they have ever disclosed their HIV positive status to that person, and if not, they will be asked if they would like to disclose to them on their own or whether they would need to be assisted to accomplish the HIV status disclosure process. The investigators will explore if disclosure to a peer-leader (as opposed to someone else within the network) facilitates retention in HIV care. Data collection procedures and methods Data will be collected through two inter-related phases: In phase 1, the investigators will collect qualitative data (through focus group discussions) on men's perception of HIV self-testing as an HIV testing strategy as well as their perceptions on receiving HIV self-test kits from trained male peer-leaders who are members of their community. Focus group discussions (FGDs) will be composed of between 8 and 12 men. Investigators will conduct six FGDs to explore people's perceptions on oral HIVST, strategies that can be used to distribute HIVST kits to men in a fishing community; and qualities of men that can be selected as peer-leaders, among other aspects. Because investigators intend to ask peer-leaders to facilitate linkage to HIV care among men who test HIV-positive, investigators will also seek people's perceptions about the acceptability of peer-leaders knowing people's status and helping with linkage to care. FGDs will be conducted by trained interviewers with experience in the conduct of qualitative interviews. All FGDs will be audio-recorded (with permission from the participants) and transcribed verbatim by the same interviewers that will have collected the data. In phase 2, investigators will collect baseline and follow-up data necessary to assess the acceptability of a peer-led HIVST intervention as well as linkage to appropriate HIV prevention, care and treatment services, and retention in HIV care among HIV-positive social network members. This phase will be implemented through four inter-related steps: Step 1 (Screening for eligibility): All social network members recommended to the study will be screened for eligibility to participate in the study using a screening tool. Only individuals recommended by peer-leaders (who will also appear on a peer-leader's pre-generated list) will be screened for eligibility, and those found to be eligible will be enrolled into the study. Step 2 (Baseline interview): All eligible social network members will be administered a baseline interview to collect socio-demographic and behavioural data, as well as data on participants' willingness to receive HIVST kits from peer-leaders, and their willingness to disclose their HIV status to a peer-leader on their own volition. Data will be collected by trained interviewers with experience in the conduct of quantitative interviews. Participants will receive a travel refund and compensation for time after participating in the baseline interviews. The baseline findings will provide the study team with information needed to measure the success or failure of the intervention. Step 3 (Follow-up visits): Follow-up interviews will be conducted at 1, 6 and 12 months post-baseline, using a follow-up questionnaire uploaded on open-data kit-enabled phones. During follow-up, individuals who received HIVST kits will be asked whether or not they used them to test for HIV. Those that will have failed to use the kits will be asked in open-ended questions to state reasons for their failure while those that will have used the kits will be asked about HIVST experiences (both positive and negative). Investigators will assess if individuals who self-tested for HIV sought confirmatory HIV testing, and if they did, whether or not they received their HIV test results. Individuals who will link to HIV care will be followed up to determine if they are still in HIV care at 6 and 12 months post-baseline. Individuals who will report that they tested HIV-positive but were yet to link to HIV care will be asked about the reasons for the delay and whether they plan to link to care in the future. Step 4 (Post-intervention qualitative interviews): At the end of the study (i.e. after month-12 follow-up visit), qualitative data will be collected from all the peer-leaders to document process issues around the distribution of HIVST kits and suggestions on how best the HIVST distribution process can be improved in the future. Investigators will conduct in-depth interviews with 30 men. Qualitative data will be collected using key informant and in-depth interview guides after obtaining written, informed consent from the participants.
