QI-Core Implementation Guide, published by HL7 International / Clinical Quality Information. This guide is not an authorized publication; it is the continuous build for version 8.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-qi-core/ and changes regularly. See the Directory of published versions
The QI key elements tag is applied to data elements that are currently used in quality measures. This list is intended to offer implementors a baseline reference point for data elements commonly used in measures.
The key QI elements were originally derived from an analysis of the 2023 QDM measures. They have since been updated based on a review of the draft FHIR measures for Measurement Period 2026, which use QI-Core STU 6. Implementors and other users should verify that the list includes all necessary data elements for the specific measures they are working with.
This table provides a quick reference across all QI-Core profiles.
