Delft Light and CAD4TB significantly enhanced TB detection in hard-to-reach areas across eight high TB burden states, showcasing efficient screening and diagnosis with a notable impact on identifying TB cases, especially among men. Discover how this technology is transforming TB care in underserved communities.

  • Delft Light and CAD4TB were distributed to eight high TB burden states with many hard-to-reach areas.
  • A parallel screening algorithm using the WHO four-symptom screen (W4SS) and CXR with CAD4TB (threshold score at 50) guided screening and identification of presumptive TB.
  • From December 2021 to June 2022, 57,732 people were screened.
  • Of these, 6,961 (17%) presumptive TB were identified and 1,472 were diagnosed with TB. Among those, 867 (59%) were clinically diagnosed with TB.
  • To diagnose a TB case, the Number Needed to Screen was 39 (Female: 50, Male: 34) and the Number Needed to Test was 5 (F: 6, M: 4), which is highly efficient.
  • The ultraportable digital X-ray with CAD has significantly improved to take high-quality TB care to hard-to-reach and vulnerable/underserved populations.
  • The interventions have been particularly effective in targeting and finding more men with TB in the community.
