ENCORE: Monitoring and evaluating treatment in South Africa with National Health Laboratory Service Data
South Africa has the largest population of HIV infected people in the world and the largest population of people on antiretroviral therapy (ART). Both the South African Government (SAG) and international donors have invested billions of ZAR annually in the country’s HIV care and treatment program. The implementation of a comprehensive monitoring and evaluation (M&E) program lagged behind the implementation of intervention rollout. As a consequence, we lack important strategic information concerning the overall effectiveness of the treatment management programme that could be used to refine treatment strategies and direct scarce resources where they are most needed. We constructed a National HIV Cohort from the complete laboratory records of South Africa’s HIV treatment program, covering over 4000 facilities. Integrating this cohort with treatment monitoring data, we are working with HE2RO to evaluate the national impact of Universal Testing and Treatment and identifying where in the UTT care cascade patients are lost to follow-up, in order to guide the next phase of South Africa’s HIV response.
