What is PHIA?

The PHIA Project, led by ICAP at Columbia University in partnership with the US Centers for Disease Control and Prevention (CDC), measures the reach and impact of HIV programs in PEPFAR-supported countries through national surveys. Each population-based HIV impact assessment (PHIA) survey offers participants household-based HIV counseling and testing conducted by trained survey staff, with return of results. The surveys also asks questions about access to preventive care and treatment services for adults and children. The results will measure national and regional progress toward UNAIDS’ 90-90-90 goals and guide HIV policy and funding priorities.

ICAP also provides technical assistance at the national level to strengthen data collection systems, enhance laboratory infrastructure, and build capacity to design, conduct, and analyze PHIAs in survey countries.

The PHIA Project team includes: the University of California, San Francisco (UCSF), Global Health Sciences (GHS)ICF International; Westat; and the Statistical Center for HIV/AIDS Research and Prevention (SCHARP). Surveys are conducted in close partnership with ministries of health and local partners in each country.

The PHIA Project builds on ICAP’s expertise in data collection and management and lab-based measurement of HIV, as well as previous experience conducting SHIMS, a large-scale population survey of 13,000 households in Swaziland.
