Considering the paucity of data informing a diagnostic approach that leads to millions of antibiotic prescriptions globally, we went on to design and conduct a randomised controlled trial aiming to generate conclusive evidence on the following gaps:

  1. Does use of trial-of-antibiotics improve diagnosis of tuberculosis?
  2. Does trial-of-antibiotics contribute to antimicrobial resistance?
  3. Can trial-of-antibiotics be safely removed from guidelines without affecting patient clinical outcomes?

This study implementation map shares the key resources for the RCT:
