Acceptability of unsupervised peer-based distribution of HIV oral self-testing for the hard-to-reach in rural KwaZulu Natal, South Africa: Results from a demonstration study.

Abstract

BackgroundInnovative models to distribute oral HIV self-tests (HIVST) provide an opportunity to increase access to HIV testing, especially for hard-to-reach populations. This study aimed to describe the acceptability of unsupervised peer-distribution of HIVST as a method to scale-up HIV testing.MethodsIn this study, lay counsellors or community health workers provided HIVST kits to primary recipients (PRs) for distribution to their sexual partners, anyone in their social network (termed secondary recipients) or for self-testing, from September 2018 to March 2020. The study was conducted in Eshowe and Mbongolwane areas in KwaZulu-Natal, South Africa. A structured questionnaire was administered during the recruitment and passive follow-up, when people came for confirmatory HIV testing. Electronic records were retrospectively examined to determine initiation of antiretroviral treatment (ART) for all HIVST users and non-users.ResultsAmong 36,708 people approached to be primary recipients, 9,891 (26.9%) accepted; 31,341 HIVST kits were distributed with a median of three (IQR: 2-4) per peer. PRs were predominately recruited at primary health clinics (PHCs). However, acceptability of HIVST was thrice as high at community-based testing sites compared to PHCs (64.5% vs. 21.0%; pConclusionUnsupervised peer-distribution of HIVST was feasible and acceptable, with more than 25% accepting to be peer-distributors. Acceptability of HIVST was thrice as high in community sites compared to clinics.
