mHealth interventions to increase HIV non-occupational post-exposure prophylaxis uptake, adherence and linkage to pre-exposure prophylaxis services in Sub-Saharan Africa: a scoping review protocol

Introduction Non-occupational post-exposure prophylaxis (nPEP) and pre-exposure prophylaxis (PrEP) are effective HIV prevention methods, but their use is low in Sub-Saharan Africa (SSA). Mobile applications (apps) could increase uptake and adherence to these interventions, yet research on their use in communities is limited. Furthermore, there is limited information on the design and development of these apps, impacting their implementation. This scoping review aims to identify, analyse and evaluate mobile apps designed to improve nPEP uptake, adherence and linkage to PrEP services focusing on key features, barriers and facilitators. It also seeks to address gaps in studies assessing the feasibility, usability and acceptability of these apps, with the goal of informing future research, healthcare policies and public health strategies to reduce the HIV burden in Sub-Saharan Africa. Methods and analysis This review will follow the Arksey and O'Malley framework and search databases such as PubMed, Scopus and Web of Science for relevant studies. Two independent reviewers will screen and assess full-text studies. Primarily, the review will include studies on digital interventions for nPEP and PrEP, excluding opinion papers, narrative reviews and sub-studies. Grey literature from sources like Google Scholar will also be considered. Data will be captured using a charting form, and results will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews framework. Completion is expected in December 2025. Ethics and dissemination No ethical approval is required as publicly available materials will be used. Results will be shared through peer-reviewed journals, conferences and with policymakers to inform HIV prevention strategies.
