TB testing among symptom-screened positive
This indicator measures the percentage of people living with HIV newly initiated on ART and screened positive for TB symptoms who then had clinical evaluation and/or appropriate TB diagnostic testing.
- Appropriate TB diagnostic testing is essential for people living with HIV who symptom-screen positive for TB.
- It is important to understand the cascade from ART enrolment to treatment of active TB disease (see Fig. 3.2); this indicator will shed light on any obstacles between positive screening for TB symptoms and proper diagnostic testing, based on national clinical guidelines.
- This is the third of five "screening cascade" indicators considered priority for high burden TB/HIV settings.
Number of people living with HIV newly initiated on ART who are investigated for active TB disease with appropriate diagnostic testing
Number of people living with HIV newly initiated on ART and screened positive for TB symptoms during the reporting period
For the numerator. Programme records (for example, ART registers, EMRs). "Appropriate" diagnostic testing refers to WHO-recommended testing modalities (1).
For the denominator. Programme records (for example, ART registers, EMRs)
(1) Policy statements on TB diagnostics and laboratory strengthening. Geneva: WHO, 2019 (https://www.who.int/tb/areas-of-work/laboratory/policy_statements/en/).
- Gender (male, female, transgender)
- Age (<15, 15+).
Consider disaggregating the type of diagnostic testing, for example, GeneXpert testing, LF-LAM, sputum acid-fast bacili (AFB) examination (alone) or other diagnostic testing.
