Meeting report of the WHO expert consultation on drug-resistant tuberculosis treatment outcome definitions, 17–19 November 2020

Book excerpt: Recent developments in TB treatment have prompted the need for revision of the TB treatment outcome definitions. An online expert consultation meeting organized by WHO’s Global TB Programme in November 2020 was to determine recent changes in TB treatment affecting treatment outcome definitions and discuss options for changing the definitions. The consultation led WHO to propose new treatment outcome definitions for drug-susceptible TB (DS-TB) and drug-resistant TB (DR-TB). The purpose of this publication is to summarise changes in the definitions of tuberculosis treatment outcomes, arising after the expert consultation. The publication is to inform a wide audience about the new definitions of TB treatment outcomes so that these definitions are readily adopted and used, globally.
