Abbreviated Name:
Antiretroviral therapy (ART) coverage
Indicator Name:
Adults and children currently receiving ART among all adults and children living with HIV
Domain:
Health System Response/ Service coverage
Related Terms:
Antiretroviral therapy (ARV), Human Immunodeficiency Virus (HIV)
Definition:
The percentage of adults and children with HIV infection currently receiving antiretroviral combination therapy in accordance with the nationally approved treatment protocols (or WHO/UNAIDS standards) among the estimated number of adults and children with HIV infection.
Measurment Method:
Numerator: The numerator can be generated by counting the number of adults and children who received antiretroviral combination therapy at the
end of the reporting period. Data can be collected from facility-based ART registers or drug supply management systems. These are then tallied and
transferred to cross-sectional monthly or quarterly reports which can then be aggregated for national totals. Patients receiving ART in the private
sector and public sector should be included in the numerator where data are available.
Denominator: The denominator is generated by estimating the number of people with advanced HIV infection requiring (in need of/eligible for) ART.
This estimation must take into consideration a variety of factors, including, but not limited to, the current number of people with HIV, the current
number of patients on ART and the natural history of HIV from infection to enrolment on ART. A standard modelling HIV estimation method, such as
in the Spectrum model, is recommended.

Estimation method:
WHO, UNAIDS and UNICEF are responsible for reporting data for this indicator at the international level, and have been compiling country specific data since 2003.Predominant type of statistics: predicted Numerator: The data on people receiving antiretroviral therapy are collected through a joint international monitoring and reporting process with WHO, UNICEF and the UNAIDS Secretariat. For this purpose a joint data tool has been developed that contains Global AIDS monitoring (GAM) indicators. Data are also compiled from the most recent reports received by WHO and/or UNAIDS from health ministries or from other reliable sources in the countries, such as bilateral partners, foundations and nongovernmental organizations that are major providers of treatment services. In order to facilitate collaboration at country level, the country offices of WHO, UNICEF and the UNAIDS Secretariat, work jointly with national counterparts and partner agencies to collate and validate data in a single collaborative consultation process. In addition, at least once a year, international data reconciliation meetings are organized to review and validate data reported to WHO, UNICEF, the UNAIDS Secretariat, the Global Fund to Fight AIDS, Tuberculosis and Malaria; and the United States President’s Emergency Plan for AIDS Relief. Where discrepancies are identified between data reported to the different organizations, follow-up letters are sent to UNAIDS, UNICEF and WHO country offices to liaise with national authorities to seek clarification and resolve discrepancies. The estimates of antiretroviral therapy coverage presented here are calculated by dividing the estimated number of people receiving antiretroviral therapy as of December by the estimated number of people living with HIV in the same year (based on UNAIDS/WHO methods).
