Abstract
INTRODUCTION: Adolescent girls and young women (AGYW) are a priority population for pre-exposure prophylaxis (PrEP), a highly effective HIV prevention method. However, effective PrEP use among AGYW has been low. Interventions to support PrEP effective use may improve pill-taking. Affordability of PrEP programs depends on their cost. We, therefore, evaluated the cost of community-based PrEP with effective use counselling. METHODS: Cost data from a randomized controlled trial were used to evaluate the cost of PrEP provision with effective use counselling offered to AGYW through community-based HIV testing platforms between November 2018 and November 2019. AGYW were randomized to receive (1) group-based community health club effective use counselling, (2) individualized effective use counselling or (3) community-based PrEP dispensary. Task shifting of effective use counselling from nurses to trained lay counsellors was implemented in groups 1 and 2. Personnel costs were estimated from time-and-motion observations and staff interviews. Expenditure and ingredients-based approaches were used to estimate costs for medical and non-medical supplies. RESULTS: In total, 603 AGYW initiated PrEP and accrued a total of 1280 months on PrEP. Average cost per person-month on PrEP with group-based community health club, individualized effective use counselling and community-based PrEP dispensary under the Department of Health scenario were similar and high (USD $55.32, $55.65 and $55.46, respectively) due to low PrEP client volume observed in the clinical trial. Increasing client volume (scaled Department of Health scenario) reduced cost per-person month estimates to USD $15.48, $26.40 and $13.99, respectively. CONCLUSIONS: As designed, individualized effective use counselling increased the cost of standard-of-care PrEP delivery by 89%, group-based community health effective use counselling increased the cost of standard-of-care PrEP delivery by 11%. These estimates can inform cost-effectiveness and budget impact analysis for PrEP provision with effective use counselling services.
