Understanding the population-based HIV impact assessment

Conducting population-based, HIV-focused household surveys is a priority for the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) as a means of monitoring HIV incidence, prevalence and program impact. The goal of the Population-based HIV Impact Assessments (PHIA) is to provide a better understanding of national and sub-national epidemic trends and population-level program achievements. PHIA surveys will be used to collect data on the uptake of HIV care and treatment services, provide real time home-based HIV counseling and testing, and estimate HIV incidence, ; CD4 T-cell counts, and viral load. For this reason, PHIA will be able to effectively serve as the HIV outcome and impact assessments needed by all stakeholders, including national HIV programs, PEPFAR, the Global Fund, and other donors and multilateral organizations, such as World Health Organization (WHO) and UNAIDS. PHIA follow the standard methods for conducting national household surveys as described by UNAIDS. PHIA are planned for Zimbabwe, Malawi, Zambia, Lesotho, Tanzania, Uganda, Swaziland, Namibia, Ethiopia, Cote d’Ivoire, Cameroon, Kenya, and Haiti. ; phia.pdf
