Change Log

This page summarizes the main changes applied to this version of the guide.

From 0.1.0-ballot to current version

🔧 Model Alignment and Refactoring

• Aligned with the Xt-EHR model v0.3.0 (FHIR-51927).
• Updated references to the latest EU Core profiles and extensions.
• Replaced usage of ConditionEuHdr and ProcedureEuHdr with ConditionEuCore and ProcedureEuCore.
• Refactored immunization and allergy profiles, including updated parent references.
• Updated modelmap.xml to reflect revised Flag references.
• Removed the eHN model and associated ConceptMaps.
• Enabled body site laterality without pre-coordination (FHIR-53428):
  • DeviceUseStatementEuHdr.bodySite now carries the R5 backport extension for DeviceUsage.bodySite, constrained to Reference(BodyStructureEuCore). The generic bodySite extension is not used, as its context of use does not cover DeviceUseStatement.bodySite.
  • BundleEuHdr gained a bodyStructure entry slice, so the referenced BodyStructure resources travel inside the document.
  • ConditionEuCore and ProcedureEuCore already provide the bodySite extension, so they needed no change.
• Added invariant dus-hdr-1 on DeviceUseStatementEuHdr.bodySite (FHIR-58916), mirroring eu-bodysite-1 from the EU core profiles: either a body site code or a reference to a BodyStructure, but not both.

🧹 Scope Reduction and Cleanup

• Removed sections no longer referenced in the specification (FHIR-51923), including:

  • Infectious Contacts, Travel History, Family History, Social History
  • Substance Use (Alcohol, Tobacco, Drugs)
  • Advance Directives, Care Team, Payers
  • Past Illness History, Medical Devices, Procedures History
• Removed obsolete profiles and rulesets
• Cleaned up unused include statements and obsolete dependency references.
• Refactored terminologies by removing unused value sets, including:
  • Encounter status, admission status, allergens, allergy substances
  • EHDSI condition POA and treatment class
  • Exposure agents and selected SDOH-related value sets

🧪 Examples and Documentation

• Updated section titles and descriptions in HDR example FSH files for clarity.
• Improved example references and corrected documentation issues.
• Added examples for post-coordinated body site laterality (FHIR-53428): a BodyStructure carrying a laterality-free structure code plus a separate laterality, referenced from a Condition, a Procedure and a DeviceUseStatement.
