TB diagnosis among those tested for TB
This indicator measures the percentage of people living with HIV newly initiated on ART and, having screened positive for active TB disease, were evaluated and/or had appropriate TB diagnostic testing who then were confirmed to have active TB disease.
- Appropriate TB diagnostic testing based on national clinical/WHO guidelines is essential for people living with HIV who 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 highlight any obstacles between diagnostic testing and TB diagnosis.
- This is the fourth of five "screening cascade" indicators considered priority for high burden TB/HIV settings.
Number of people living with HIV newly initiated on ART who were diagnosed as having active TB disease
Number of people living with HIV who newly initiated ART and screened positive for TB symptoms who had appropriate diagnostic testing during the reporting period
For the numerator. Programme records (for example, ART registers, EMRs)
For the denominator. Programme records (for example, ART registers, EMRs). "Appropriate" diagnostic testing refers to WHO-recommended testing modalities (1).
