Integrated PrEP and STI Services for Transgender Women in Uganda: Qualitative Findings from a Randomized Trial

Tenofovir alafenamide fumarate (F/TAF) pre-exposure prophylaxis (PrEP) is understudied in sub-Saharan Africa. The Tandika PrEP study was a randomized trial that evaluated same-day F/TAF initiation, the impact of drug-level feedback on PrEP adherence, and integrated PrEP and sexually transmitted infection (STI) services for HIV-negative transgender women (TGW) in Uganda (NCT04491422). From April 2022-February 2023, a qualitative sub-study of 30 in-depth interviews explored (1) perspectives on same-day initiation of F/TAF PrEP, (2) experiences of urine tenofovir testing and drug-level feedback, and (3) descriptions of self-collection of samples for STI testing. Qualitative data were analyzed using an inductive content analytic approach. Integrated PrEP/STI services were valued by TGW because the convenience of urine testing motivated adherence and allowed for tenofovir and STI detection. (1) Preferred characteristics: F/TAF-based PrEP was easy to take and not readily identifiable as an HIV-related medication, resulting in less stigma than the better-known tenofovir disoproxil fumarate (F/TDF). Weight gain associated with F/TAF use was viewed positively by TGW as a symbol of health and prosperity in African settings. (2) Adherence motivation: PrEP adherence was motivated by a desire not to disappoint healthcare workers; TGW reciprocated adherence support and drug-level feedback by taking PrEP. (3) Facilitating adherence and STI care: Urine testing enhanced STI detection and treatment. Utilization of urine for tenofovir and STI testing motivated the uptake of HIV/STI care, emphasizing the importance of integrated PrEP and STI services. Integrating PrEP/STI services into differentiated delivery models could increase prevention uptake in this vulnerable population.
