Technical basis of the endTB observational study

endTB Observational Study had sites in 17 countries. In each country, sites enrolled patients on treatment with bedaquiline and delamanid according to National TB Program guidelines, while collecting clinical and bacteriological data on efficacy and safety. Because many of the endTB Observational Study tools were found to be useful for clinicians and programs that were starting to use the new TB drugs and regimens, we made them freely available at the endTB website. This Technical Basis document provides the rationale for clinical decision-making, screening tools and data definitions that are used at the endTB Observational Study sites.
