Estimation of antiretroviral therapy coverage: methodology and trends

Mary Mahy et al. Curr Opin HIV AIDS. 2010 Jan.

Abstract

Purpose of review: To present the methodology used to calculate coverage of antiretroviral therapy (ART) and review global and regional trends in ART coverage.

Recent findings: There has been a steady increase in ART coverage over the last decade with a more rapid increase in recent years. Current estimates of ART coverage are 43% for adults and 38% for children (ages 0-14 years). Methods for calculating coverage rely on good-quality patient monitoring systems in countries, and well informed models are needed to estimate the number of people in need of treatment.

Summary: The estimated coverage rates show that ART programs have improved over the past 8 years; however, approximately 58% (53-60%) of those people in need of ART are still not on treatment. High quality data are needed to accurately measure changes in ART coverage.
