EQUIP: Economic evaluations of differentiated models of service delivery
Countries around the world have adopted the UNAIDS global “90-90-90” targets for HIV management: 90% of those infected know their status; 90% of those who know that they are infected are on antiretroviral therapy (ART); and 90% of those on ART are virally suppressed. EQUIP is a global cooperative agreement between USAID and a consortium of African organizations to provide support and technical assistance to USAID countries to foster achievement of 90-90-90. BUSPH is a supporting partner in the EQUIP consortium, with a focus on economic evaluation and other data analysis. Projects including measuring and modeling the cost-effectiveness of different approaches to ART service delivery; national-level modeling of the impact and budgetary requirements of meeting the targets; and research on viral load testing scaleup, integrated treatment of HIV and HCV, and other related topics.
Under EQUIP, we conducted several evaluations of the costs of differentiated models of service delivery (DSD) for HIV treatment. In Zambia and Uganda, these evaluations required obtaining primary, patient-level data from a wide range of implementing partners, which are nongovernmental organizations that help national ministries of health to implement their policies, often with funding from PEPFAR or the Global Fund. We estimated patient outcomes, cost per patient treated and per patient successfully treated, and cost-effectiveness of alternative models for managing stable ART patients in these two countries.
In Lesotho and Zimbabwe, where the evaluations were carried out by another EQUIP partner, we generated the cost estimates using data provided to us. Finally, in Malawi and Zambia, we served as co-investigators for the INTERVAL trial, which assessed the effectiveness and cost of six-month dispensing of antiretroviral medications.
