Co-management of tuberculosis and HIV treatment
Progress in detecting and treating TB and HIV among people with HIV-associated TB.
TB is a leading cause of morbidity and mortality among people living with HIV, including those receiving antiretroviral therapy. Prompt TB treatment and early antiretroviral therapy are critical for reducing the mortality due to HIV-associated TB and must be the highest-priority activity for both the AIDS Programme and National TB Programme. A measure of the percentage of HIV-positive TB patients that access appropriate treatment for their TB and HIV is therefore very important
Number of HIV-positive new and relapse TB patients started on TB treatment during the reporting period who were already on antiretroviral therapy or started on antiretroviral therapy during TB treatment within the reporting year
Estimated number of incident TB cases in people living with HIV
For the numerator: Facility antiretroviral therapy registers and reports; programme monitoring tools. Count the total number of HIV-positive new and relapse TB patients who were started on TB treatment (as recorded in the TB register) and antiretroviral therapy, or those already on antiretroviral therapy (as recorded in the antiretroviral therapy register). The information should be reconciled quarterly and annually with the TB registers in the relevant basic management units before consolidation and reporting.
For the denominator: Programme data and estimates of incident TB cases among people living with HIV. WHO calculates annual estimates of the number of incident TB cases in people living with HIV. The denominator estimates, provided by countries on notification and antiretroviral therapy coverage, become available only in August of the reporting year and do not need to be provided at the time of reporting. The estimates for 2019 are available at http://www.who.int/tb/country/data/download/en.
See Annex 5 for further understanding of the indicator (Annex 5 of the 2022 Global AIDS Monitoring (GAM) guidelines).
Data should be collected continuously at the facility level, reconciled with the TB registers and aggregated periodically, preferably monthly or quarterly, and reported annually. The most recent year for which data and estimates are available should be reported here.
- Age (<15 and 15+ years).
- Cities and other administrative areas of epidemiologic importance.
Please provide city-specific data for this indicator. Space has been created in the data entry sheet to provide information for the capital city and one or two other key cities of high epidemiological relevance, such as those with the highest HIV burden or those that have committed to ending AIDS by 2030.
Adequate detection and treatment of TB will prolong the lives of people living with HIV and reduce the community burden of TB. WHO provides annual estimates of the burden of TB among people living with HIV, based on the best available country estimates of HIV prevalence and TB incidence. All people living with HIV newly infected with TB should start TB treatment and antiretroviral therapy within eight weeks of starting TB treatment, regardless of CD4 count. The people with both HIV and TB with profound immunosuppression (such as CD4 counts less than 50 cells/mm3) should receive antiretroviral therapy within the first two weeks of initiating TB treatment. TB treatment should be started in accordance with national TB programme guidelines.
This indicator measures the extent to which collaboration between national TB and HIV programmes ensures that people living with HIV and TB are able to access appropriate treatment for both diseases. However, this indicator will be affected by low uptake of HIV testing, poor access to HIV care services and antiretroviral therapy and poor access to TB diagnosis and treatment. Separate indicators for each of these factors should be referred to when interpreting the results of this indicator.
It is important that those providing HIV care and antiretroviral therapy record TB diagnosis and treatment, since this information has implications for antiretroviral therapy eligibility and choice of antiretroviral regimen. It is therefore recommended that the date TB treatment starts be recorded in the antiretroviral register.
