2. EPIC2 - Pooled and Adjusted EPIC Data

Pooled EPIC2 data with original country-specific codes maintained. Files can be downloaded in .csv format.

The main dataset (facility_dataset) contains all core variables used for the pooled analysis of EPIC studies which include general facility information, immunization related facility information, inputs (labor, vehicles, building), outputs (doses, FIC, DTP and Measles), total cost and cost by input and activity.

Accompanying datasets contains detailed information on labor (labor_dataset) , vaccines (coming soon), and cold chain by facility (coming soon). Contextualization variables generated from DHS survey datasets are available on the second section of the dataverse (2. DHS Contextual Data - Regional). These accompanying datasets are linked to the main dataset with facility ID

“Adjustments for the EPIC-2 data is conducted with advice and input from data collection team (EPIC-1). The magnitude of these adjustments are documented in the table attached. These documented adjustments explained the lion’s share of the discrepancies, leaving only minor unaccounted differences in the data (Δ range 0% - 1.1%).”

“In addition to using the sampling weights, any extrapolation to achieve nationwide cost estimates for Benin, Ghana, Zambia, and Honduras uses scale-up factor to take into account facilities that are outside of the sampling frame. For example, after taking into account the sampling weights, the total facility-level delivery cost in Benin sampling frame (343 facilities) is $2,094,031. To estimate the total facility-level delivery cost in the entire country of Benin (695 facilities), the sample-frame cost estimate is multiplied by 695/343.

“Additional adjustments for the EPIC-2 analysis include the series of decisions for weighting, methods, and data sources. For EPIC-2 analyses, average costs per dose and DTP3 were calculated as total costs divided by total outputs, representing a funder’s perspective. We also report results as a simple average of the site-level cost per output. All estimates were adjusted for survey weighting. In particular, the analyses in EPIC-2 relied exclusively on information from the sample, whereas in some instance EPIC-1 teams were able to strategically leverage other available data sources.”
