Scope of the guideline update

The scope of the 2021 update of the DS-TB treatment guideline was to consolidate in one document all the previous evidence-based policy recommendations on treatment of DS-TB (previously presented in two separate guideline documents) and to add new recommendations. Thus the current module brings together all recommendations that are valid from previous guidelines without any modifications as no additional reviews have been performed. In addition to these previous valid recommendations, the 2021 update presents new recommendations on the 4-month regimens emerging from the Guideline Development Group (GDG) meetings in 2021. Now that the guidelines are consolidated, WHO will strive to review and update individual recommendations based on the emerging evidence.
