Incremental costs of integrated PrEP provision and effective use counselling in community-based platforms for adolescent girls and young women in South Africa: an observational study.

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.
