Abstract

Comparing estimates of the cost-effectiveness of human immunodeficiency virus (HIV) interventions can help communities select an HIV prevention portfolio to meet local needs efficiently. The authors developed a spreadsheet tool to estimate the relative cost-effectiveness of 26 HIV prevention interventions. HIV prevalence of the population at risk and the cost per person reached were the two most important factors determining cost-effectiveness. In low-prevalence populations, the most cost-effective interventions had a low per-person cost. Among the most cost-effective interventions overall were showing videos in sexually transmitted disease clinics and raising alcohol taxes.
