Adolescents living with HIV (ALHIV) on antiretroviral therapy (ART) globally report lower rates of viral suppression because of challenges to remain adherent and engage in HIV treatment. Psychosocial support is critical to meet the unique needs of ALHIV. Peer navigation has been found to be effective in supporting adults in ART adherence, but the evidence for adolescents is scant. Given the large proportion of adolescents on ART in sub-Saharan Africa, peers hold promise to deliver psychosocial support. The aim of this qualitative evidence synthesis is to review qualitative and mixed-methods studies describing experiences of peer navigation and support interventions for ALHIV on ART in sub-Saharan Africa.

The population–concept–context configuration will be applied to identify suitable studies on ALHIV and on ART (population) and experiences of peer navigation and support (concept) and conducted in sub-Saharan African countries (context). The review will only include studies published in the English language. The following databases will be searched: PubMed, Wiley Library Online, EbscoHost (PsycArticles), MEDLINE, Scopus, CINAHL, WHO database and Google Scholar, for eligible qualitative studies published from January 2015 (to ensure relevance) to November 2025. Two-stage screening will be done by two reviewers independently. Extracted data will be thematically analysed with Atlas.Ti (v25) software. A narrative synthesis will be conducted to describe the reported outcomes, experiences and challenges with receiving and delivery of peer navigation and support interventions in sub-Saharan Africa. The review will adhere to Preferred Reporting Items for Systematic reviews and Meta-Analyses and Enhancing Transparency in Reporting the Synthesis of Qualitative Research reporting guidelines.

Ethics approval is not required for this qualitative evidence synthesis. The findings will be submitted to a peer-reviewed journal and disseminated to via conference proceedings.
