Uganda – TB screening among people living with HIV using Delft Light and CAD4TB
People living with HIV are at increased risk of TB and often require intensified screening. TB screening was implemented at selected health facilities in Uganda to improve case detection among this priority population.
Facility-based screening for PLHIV
Five health facilities conducted TB screening among people living with HIV.
Using ultra-PDX with CAD4TB
Screening was performed using digital chest X-ray supported by CAD4TB.
Identify presumptive TB cases
Individuals with CAD4TB scores above 60 were identified as presumptive TB cases.
Confirmatory testing
Presumptive TB cases were tested using Xpert MTB/RIF, and confirmed cases initiated TB treatment.
From July 2020 to November 2021,
- Among those screened, 22.7% were PLHIV, 165 (16.3%) had abnormal CXR, and 20 PLHIV (21.5%) were confirmed with TB.
- TB screening with CXR improved TB case detection with higher yield among PLHIV and contacts compared to other groups.
- Using digital X-rays and CAD for routine screening of TB among PLHIV in care should be prioritised for early TB diagnosis, treatment initiation and improved outcomes.
