The Immunization Calculation Engine (ICE) project team is interested in ensuring that as the ICE software evolves it can continue to serve diverse technical environments with as much ease as possible for the adopter. The ICE service is currently either being used in Public Health and Provider settings and/or being integrated within EHRs and Immunization Information Systems (IISs). 

The ICE rules and request-response messages are both currently based on the Virtual Medical Record (vMR) and support a version of the HL7 Decision Support Service (DSS) specification. 

One goal of this pilot was to ensure that ICE is based on the latest viable CDS standards and, at minimum, can support requests from ICE clients to the ICE service based on FHIR messages that are compatible with QUICK. By doing so, the pilot demonstrated that the dataset used by a typical immunization forecaster can be properly supported by the CQF standards and that the CQF standards could be leveraged by other immunization forecasters. 

In short, this pilot intended to examine existing FHIR resources available for immunization forecasting, analyze how well an end-to-end FHIR request and response based on those resources align with QUICK, and demonstrate via a live system - using existing immunization forecasting rules implemented in ICE - that immunization histories can be properly evaluated and forecasted.
