WHO-recommended set of indicators to monitor HIV drug resistance prevention at antiretroviral treatment sites

This document describes one key element in the recommended HIV drug resistance (HIVDR) assessment strategy: antiretroviral treatment (ART) site-based HIVDR Early Warning Indicators (EWIs). These indicators are ART site factors that may be associated with preventable emergence of HIVDR, and can be acted on at the ART site or programme level. Results can inform national decision-making on ART programme planning and other HIVDR prevention measures.
