Putting youth at the centre: co-design of a community-based intervention to improve HIV outcomes among youth in Zimbabwe.

Background:  Youth have disproportionately poor HIV outcomes. We aimed to co-design a community-based intervention with youth to improve HIV outcomes among 16-24 year-olds, to be trialled in Zimbabwe. Methods:  We conducted 90 in-depth interviews with youth, family members, community gatekeepers and healthcare providers to understand the barriers to uptake of existing HIV services. The interviews informed an outline intervention, which was refined through two participatory workshops with youth, and subsequent pilot-testing. Results:  Participants considered existing services inaccessible and unappealing: health facilities were perceived to be for 'sick people', centred around HIV and served by judgemental providers. Proposed features of an intervention to overcome these barriers included: i) delivery in a youth-only community space; ii) integration of HIV services with broader health services; iii) non-judgemental skilled healthcare providers; iv) entertainment to encourage attendance; and v) tailored timings and outreach. The intervention framework stands on three core pillars, based on optimizing access (community-based youth-friendly settings); uptake and acceptability (service branding, confidentiality, and social activities); and content and quality (integrated HIV care cascade, high quality products, and trained providers). Conclusions:  Ongoing meaningful youth engagement is critical to designing HIV interventions if access, uptake, and coverage is to be achieved.
