Core Data Elements For IIS Functional Standards v4.0

The CDC endorsed data elements represent the data elements that are needed by an IIS to record patient demographics and vaccination events to meet the IIS Functional Standards v4.0. An IIS should store the CDC endorsed data elements listed below if the elements are sent from an external information system and meet the IIS’s data quality criteria. This list does not include all data elements external information systems such as EHRs, vital records, practice management or billing systems are expected to send to an IIS. The list may not include all data elements an IIS produces, stores or sends. Data elements may be derived and architectural solution may differ among IIS.

Definitions of the CDC endorsed data elements below can be found at:
