Private-sector Access to Testing for Health Sustainability

New and innovative strategies are urgently needed to increase the uptake of HIV prevention and sexual and reproductive health services among adolescent girls and young women (AGYW) in sub-Saharan Africa. To ensure the real-world sustainability of free distribution of HIV self-test kits to AGYW by private drug shops and pharmacies, investigators will rigorously test supply-side subsidy structures for shopkeepers' provision of HIV-self test kits to AGYW combined with prosocial motivational supports. The combination of non-monetary and monetary support structures aims to emulate real-world health financing models for public-private partnerships and ultimately aims to improve equity in access to critical prevention services for AGYW at scale.

This is an implementation-effectiveness trial that tests program adoption, implementation, and maintenance of free HIV self-test kit (HIVST) distribution to adolescent girls and young women (AGYW) financed by profits from HIVST kit sales to non-AGYW customers. To initiate adoption, the study will offer pharmacy and drug shopkeepers the opportunity to procure subsidized HIVST to simultaneously distribute to AGYW for free (reimbursed by the study mimicking government-supported provision) and sell to non-AGYW customers for profit, gradually phasing out procurement subsidies over 36 months to test maintenance of the segmented pricing model for real-world sustainability (Aim 1). Investigators will implement non-monetary motivation boosters to sustain shopkeeper engagement over the study period and use mixed-methods to understand shopkeepers' experiences and necessary conditions for program maintenance and provider behavior change (Aim 2), which will inform the co-design of a progressive scale-up plan to achieve national coverage with Tanzanian AGYW, public, and private partnership stakeholders (Aim 3). At the study's conclusion, investigators will have a comprehensive understanding of the support structures shops need to sustain HIVST kit provision for AGYW. Importantly, the study will contribute to generalizable learning about the structures required for commercially sustainable public-private partnerships for high-impact public health interventions.
