A Simple Intervention to Increase Persistence on PrEP in MSM to Improve Decision Making

Description

Oral HIV pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention modality that requires individuals to take a daily tablet to prevent themselves acquiring HIV. In South Africa while this is freely available in the public sector, persistence (that is continuation after initiation) is low amongst vulnerable populations, including men who have sex with men (MSM). This study is a feasibility and acceptability study of a behavioral economics informed intervention to improve persistence amongst MSM newly initiating PrEP in South Africa. The goal of this study is to show that this approach is possible in a routine setting and gather the necessary data for a fully powered effectiveness trial. Study participants will complete a baseline questionnaire and then be randomized to either receive standard of care (control) or to receive the intervention. The intervention package consists of evidence informed reminders, commitment pledges and planning prompts. The intervention package aims to address present bias, optimism bias and salience. The intervention is delivered and the enrollment visit and then through mobile phone reminders / text messages. There is no further in person interaction after the initial interaction. Participants may be contacted for a telephonic enplane questionnaire. Outcome data is obtained from passive followup through routine medical record review with the primary end point being persistence at 3 months.
