Description

Utilizing a participatory approach, an open call for submissions was published to engage young people in partnerships with certified community-based organizations in Nigeria. This initiative encouraged them to share their ideas, experiences, and perspectives on how community-based organizations can sustain or enhance HIV self-testing (HIVST) and youth-friendly preventive services for at-risk adolescents and young adults. During the open call, 123 submissions were received from 178 young adults and adolescents aged 14-24, offering a variety of capacity-building and adaptable ideas, such as peer health education and community engagement activities. In the designathon phase, where youth refined their ideas, 10 teams comprising 40 participants were involved, with 24 teams focusing on mobile health outreach, 8 adapting health messaging to sports, and 8 creating safe spaces for marginalized communities.

Five teams (n=20) were invited to a 4-week hybrid innovative Bootcamp to further refine their sustainment strategy, which involved training the trainers (1 team), tailoring services (1 team), creating safe spaces (1 team), modifying vans (1 team), and adapting health messaging for sporting events (1 team). All teams were awarded prizes. Strategies from all teams were combined to form the enhanced sustainability strategy for this clinical trial. In this hybrid type 2 implementation-effectiveness trial, cluster randomization will occur in a parallel group approach, with phased enrollment to standard 4YBY for all study arms, followed by an enhanced condition for CBOs randomized to the intervention condition. This study protocol will involve undertaking a prospective three-year assessment of the sustained intervention focused on the sustainment of the 4YBY core elements and uptake of HIV prevention services (HIV testing/ retesting, STI testing/treatment, PrEP adherence), sustained capacity to implement the 4YBY program, youth engagement, and reach

Step 1: Participant enrollment and baseline data collection. This will involve recruiting youth to participate in the randomized controlled trial. Participant recruitment strategies will include social media, online, event- and venue-based, participant referral, and community and school-based referrals. Participant enrollment will be completed by the study team.

Step 2: Intervention implementation. Following participant recruitment and enrollment in the study. All 40 sites will receive standard 4YBY implementation (4YBY-S), with 20 sites with matched CBOs randomized to receive standard with enhanced sustainability strategy (4YBY-E). 4YBY-S includes the continuation of standard 4YBY activities, benefits, and capacities at all participating CBOs. The Enhanced Sustainability Strategy package includes developing formal commitments and sustainability blueprint (herein referred to as PLAN) for 4YBY at randomized CBOs that includes all goals and strategies, timeframes, and milestones as well as; 1) people (i.e. identify and prepare champions known as sustainability teams); 2) learning (create a bi-weekly collaborative to improve learning, sustainability, and network weaving that promote information sharing, collaborative problem solving and shared vision/goal with sustaining 4YBY); 3) adaptation monitoring (promote and monitor adaptation to meet local needs); and 4) access to nurturing coaches (provide supportive climate and technical assistance with sustainability as well as audit and feedback)

Step 3: The investigators will conduct follow-up surveys across all 4YBY communities and CBOs and among AYA in the cohort at baseline and every six months for 24 months. Participants will use their mobile phone numbers to access the survey in person or online. Reminders will be sent via text message. The completion of the surveys will be tracked in an online database. Follow-up surveys will also be conducted to assess intervention sustainment every six months for 24 months. Additionally, every implementation encounter (i.e., initial or ongoing training, implementation of the 4YBY program, and use of sustainment strategies by the trained CHWs) will be documented in an electronic implementation dashboard maintained by the NIMR study team that will include encounter length time, time spent on 4YBY program implementation, and a checklist of implementation and sustainment strategies used.
