The Quality Data Implementation (QDI) User Group is a group of volunteer members who use the QDM and Fast Healthcare Interoperability Resource (FHIR)-related standards. The group seeks to understand data capture and use with respect to workflow in health IT implementations such that measure requests for data are feasible and provide accurate, comprehensive, and reliable data for evaluation. The data model efforts support the Electronic Clinical Quality Improvement (eCQI) landscape and the evolving transition from the Quality Data Model (QDM) to the FHIR model (Quality Improvement Core – QI-Core) for authoring Electronic Clinical Quality Measures (eCQMs) and Digital Quality Measures (dQMs).
