Behaviourally-informed two-way text messaging to improve return to HIV care in South Africa: evidence from a randomised controlled trial.

Introduction: One-way text messaging to re-engage people in HIV care has shown promise, but little is known about two-way messaging where the recipient is asked to respond. We evaluated a two-way text messaging intervention, informed by behavioural science, to increase re-engagement in care following missed antiretroviral therapy (ART) visits.

Methods: We conducted an individual-level randomised controlled trial between February and March 2023 in Capricorn District, South Africa.

A randomized trial of 'fresh start' text messaging to improve return to care in people with HIV who missed appointments in South Africa.

Objective: Treatment interruptions are a barrier to successful antiretroviral therapy (ART). 'Fresh start messages', which leverage significant days on the calendar (e.g.

Indicator-focussed technical assistance in South Africa's HIV programme: A stepped-wedge evaluation.

Background: There is a lack of research on technical assistance (TA) interventions in low- and middle-income countries. Variation in local contexts requires tailor-made approaches to TA that are structured and replicable across intervention sites whilst retaining the flexibility to adapt to local contexts. We developed a systematic process of TA using multidisciplinary roving teams to provide support across the various elements comprising local HIV services.
