Pakistan – Active case finding using OneStopTB Clinic with CAD4TB
Community-based active case finding using the OneStopTB Clinic and CAD4TB enabled large-scale screening and early TB detection. The intervention identified a substantial number of bacteriologically and clinically diagnosed TB cases, demonstrating its effectiveness in hard-to-reach areas.
Mobile TB screening clinics
The OneStopTB Clinic equipped with digital X-ray and CAD4TB was deployed at outreach camps.
AI-supported presumptive identification
Individuals with CAD4TB scores of ≥70 were identified as presumptive TB cases and tested.
Clinical evaluation of intermediate scores
Individuals with CAD4TB scores between 50 and 70 were clinically evaluated by a doctor.
Molecular confirmation
Presumptive TB cases were tested using Xpert for bacteriological confirmation.
78,885 individuals visited camps. Of these,
- Those having a CAD4TB score between 50 and 70 were clinically evaluated by a doctor.
- 1,187 were bacteriologically positive, 1,627 were clinically diagnosed, 62 were EP and 37 were detected as having RR-TB.
- ACF intervention is an effective strategy to find missing TB cases in hard-to-reach areas and enables early TB diagnosis.
