The Acceptability, Feasibility, and Preliminary Effectiveness of a Courier HIV-Treatment Delivery and SMS Support Intervention for Young People Living With HIV in South Africa.

Abstract

Young people living with HIV (YPLWH) experience poorer rates of virological suppression compared with adults. Differentiated service delivery models for YPLWH are urgently needed to address this disparity. Participants were recruited from an HIV treatment clinic near Cape Town, South Africa. We conducted a longitudinal pilot study to examine the acceptability, feasibility, and preliminary effectiveness of a courier ART delivery and SMS support intervention to retain YPLWH (13-24 years) in care during COVID-19. YPLWH had the option to enroll in the courier service and were randomized 1:1 to receive adherence support via a weekly SMS. Modified Poisson regression was used to estimate the preliminary effectiveness of the courier intervention on viral suppression (HIV-1 RNA <200 copies/mL) at months 3 and 6. Among 215 participants, 82% elected to enroll in the courier ART service at baseline, 41% reported receiving a delivery in the past 3 months at month 3, and 49% reported receiving a delivery in the past 3 months at month 6. Among those who received a delivery, most (91%-100%) rated the intervention as acceptable. Participants who reported receiving a delivery in the past 3 months at month 3 were 1.26 (95% CI: 1.05, 1.54) times as likely to have a suppressed viral load at month 3 and 1.21 (0.99, 1.48) times as likely at month 6, controlling for potential confounders. Findings reveal high uptake and acceptability of a courier ART delivery intervention among YPLWH and promising evidence for its effectiveness in increasing the probability of viral suppression. A fully powered trial is warranted.
