Two-way Texting for VMMC Follow-up in Republic of South Africa

Voluntary medical male circumcision (alternatively abbreviated in the literature as VMMC or MC) is a critical HIV prevention intervention with global support for expansion across sub-Saharan Africa (SSA). MC is safe: routine programs in SSA report adverse event (AE) rates well under 2%. Nevertheless, global MC guidelines require one or more follow-up visits within 14 days for AE detection. Our prior research in Zimbabwe employed two-way texting (2wT) between patients and providers to focus follow-up on men with potential AEs, allowing men healing without complication to opt-out of routine post-operative visits. 2wT safely reduced client visits by 85%, suggesting that 2wT can make MC services dramatically more efficient while maintaining safety. In the Republic of South Africa (RSA), high-volume urban clinics, remote service delivery, and low AE identification threaten quality at scale. Across more than 500,000 annual MCs performed, up to 1 million multi-stage, unnecessary MC reviews are likely conducted. RSA pressure for MC expansion and severe health system constraints, combined with good cell coverage, suggest 2wT's impact would be significant for MC care quality and efficiency, especially in rural areas. A randomized control trial (RCT) will rigorously evaluate how 2wT improves AE ascertainment and follow-up efficiency in urban and rural clinics. We aim to conduct an RCT to determine how 2wT increases AE ascertainment while reducing workload in the RSA implementation context. While the overall protocol covers multiple components over a 5-year study, this registration is specific to the RCT, aim 1.
