This survey was conducted as part of the Gavi Full Country Evaluation (FCE) project in Zambia. Gavi FCEs are prospective studies covering the period 2013-2016 that aim to assess the barriers to and drivers of immunization program performance. The Zambia FCE Health Facility Survey was conducted in 22 districts purposely selected to overlap with those where a baseline facility survey for the Access, Bottlenecks, Costs, and Equity (ABCE) Project in Zambia was performed. The districts provide a geographically and demographically representative sample of Zambia’s health system. For this survey, data on financing, staffing, facility procedures and guidelines, vaccine stocks, and supply delivery (including cold chain temperature measurements) were collected from a representative sample of 171 health facilities. Data were collected through interviews of health providers, direct observation of facility areas, and assisted observation of immunization sessions.
