  • Harnessing Male Peer Networks to Enhance Engagement With HIV Prevention

    The study will use a cluster-randomised trial design with clusters based on existing village boundaries, which have been utilised as part of an ongoing population-based HIV surveillance. In some cases, neighbouring villages will be aggregated to give approximately equal numbers of adult men in each cluster. The study cohort from which participants will be recruited is located in Manicaland province, east Zimbabwe. The intervention will proceed with the following steps: i. Potential primary distributors will be identified by the research team following engagement with local key informants, these individuals will be contacted and screened for study enrolment. The desired characteristics of these individuals would be that they are members of their community with strong local networks of peers. If they choose to participate an informed consent procedure will be completed by the fieldworkers. ii. If enrolled, the distributor will be given a pack containing four HIVST kits, one for their own use and three for distribution within the cluster. The study team will collect basic demographic data (name/age / cell number) for the distributor and the intended recipients. They will also record the unique ID of the pack of kits. Advice will be provided on the correct use and interpretation of the HIVST, the need for post-test confirmatory testing in a health facility and the availability of HIV prevention methods including PrEP. iii. The distributor will be asked to give the test kits to the intended recipients within a seven-day period. iv. After seven days the helpdesk will contact the distributor and the intended recipients to ascertain whether kits have been received and used, to collect behavioural HIV risk data for the recipients and encourage attendance at a healthcare facility for a confirmatory test. If they have not yet distributed the test kits, the helpline will follow-up at regular intervals to see if distribution has happened. HIVST recipients will be invited to complete the informed consent over the telephone and be enrolled in the study. Follow-up calls will be made to these individuals if necessary. Recipients will be encouraged to consider becoming distributors and advised on the location of community facilities (shops, pharmacies, hairdressers etc.) from where they can obtain the HIVST packs for distribution. This method of HIVST distribution through community-based hubs has been proven to be successful in studies in other Sub-Saharan African settings. [48] A small incentive of USD1:00 will be transferred electronically to the initial distributor for each kit successfully distributed. Successful distribution to peers is defined as the peer having received the HIVST and has been successfully contacted by the helpline to confirm receipt of the HIVST but does not have to use the HIVST or agree to enrol in the study as a distributor. Names and cell numbers will be collected for intended recipients by the study team and stored confidentially. v. If the recipient chooses to become a distributor, they will go to the community facility and the owner will check using a real-time database that they are eligible. If they pass this screening, they will be given a pack of three HIVST kits for within cluster distribution. If distributors successfully distribute all three HIVST kits within their clusters, they will have the option to collect a further three HIVST kits (up to a total maximum of six HIVST kits) from the community facility. A small remuneration of USD1:00 will be paid to the facility owner for each pack of kits distributed. vi. After seven days the helpdesk will contact the second level recipients and steps iv) and v) will be repeated until all kits allocated to a particular community have been distributed. vii. When participants attend a clinic for confirmatory testing, they will return the referral form which was enclosed with the HIVST kit which has a unique barcode and based on their self-reported HIVST result (unreactive/reactive) be screened for PrEP or ART. The outcome of the screening will be recorded in a tick-box on the label and the packaging deposited in a secure box at the clinic from where it will be collected by the study team. viii. Referral forms, HIVST kits and HIVST packaging will be returned to the central data processing facility for data entry and an additional USD1:00 remuneration will be paid to each individual attending the clinic and participating in a confirmatory HIV test. ix. All individuals initiating PrEP or ART will be contacted monthly for six months to provide support and to ascertain whether they are still adhering to/continuing with PrEP/ART. x. Additionally, we will contact all men who report they are still taking PrEP/ART at the end of the follow-up period in order to obtain a dry blood spot to verify the self-report of adherence. This will be sent for analysis in order to assess the intracellular levels of tenofovir diphosphate (TFV-DP) in red blood cells.
