HIV self-testing for partners of postpartum women to facilitate HIV pre-exposure prophylaxis and antiretroviral therapy uptake: a protocol to adapt and pilot an intervention via a pilot randomised controlled trial in South Africa.

introductionSouth African women are vulnerable to HIV acquisition during the postpartum period which can result in perinatal transmission via breastfeeding; many male partners do not know their HIV status. Biomedical approaches to preventing HIV for postpartum women include pre-exposure prophylaxis (PrEP) and antiretroviral treatment for male partners with HIV. Gaps in implementation include low uptake of PrEP among postpartum women and infrequent testing of men who may be motivated to test for HIV to protect the health of their infant. METHODS AND ANALYSIS: We will conduct a randomised pilot trial in KwaZulu-Natal (KZN) Province, South Africa among postpartum women and their male partners. The study will pilot a combination intervention consisting of cognitive behavioural strategies (including communication skills training, motivational interviewing and problem-solving) to promote ETHICS AND DISSEMINATION: Ethics approval for this study was obtained from the Human Research Ethics Committee at The University of the Witwatersrand, Johannesburg, South Africa (Reference number: 250612) and the Institutional Review Boards at Massachusetts General Brigham (2025P002271, Boston, Massachusetts, USA) and the University of Alabama at Birmingham (300015167, Birmingham, Alabama, USA) in the USA. Site support and approvals were obtained from the health facility and the KwaZulu-Natal Provincial Department of Health. Results will be disseminated through peer-reviewed manuscripts, reports and both local and international presentations. TRIAL REGISTRATION NUMBER: NCT07194902.
