Work Item Proposals Discussed

MHD FHIR R5

Goal. Provide an MHD on FHIR R5 track in parallel to today’s normative MHD on FHIR R4 This will not deprecate R4. This is funded/sponsored by IHE-Europe.

Editorial/Packaging approach
  • Create a versioned branch of the MHD repo for the R5 work.
  • Publish as a new major line with a suffix (e.g., 5.0.0-R5) so it’s clearly not replacing the 4.x line; R4 remains the recommended publication. And the version tested at connectathons
  • IHE normally avoids multiple simultaneously-published versions; this plan intentionally carves out a method to keep both visible until a future convergence (likely at FHIR R6).
Technical notes
  • Many sections of MHD don’t change; the big changes are in DocumentReference.
  • AuditEvent: profile directly for R5 (not strictly via BALP), keeping consistent with a future BALP upgrade.
  • Dependencies: PDQm should be fine (normative resources); FormatCode is vocabulary (version-agnostic); IUA is version-agnostic; MHDS update is out of scope.

Timeline: Europe/EHDS would like a TI as early as Dec 2025; recognize this stresses normal governance. Aim to get as close as feasible.

Actors/options: Ensure both Source and Responder variants are supported where relevant; keep options tightly scoped and testable.

National/Regional use: Treat R5 line as suitable for national extensions and European projectathons (EHDS) while avoiding pressure on global sites to switch.

Maintenance risk: Running two live lines (R4 & R5) adds overhead; keep diffs minimal and document precise deltas.

Future: Expect broad convergence at FHIR R6; the R5 branching/packaging pattern will inform how to run dual lines for other profiles later.

Full-Text Search for Document Sharing

Goal. Add server-side cross-document full-text search to IHE Document Sharing so clinicians can find relevant unstructured documents (e.g., PDFs) without opening each one.

Key takeaways from discussion
  • Complements existing metadata and structured-data queries (XDS/MHD, mXDE, QEDm).
  • Scope is limited to MHD unstructured content search; leave structured extraction to existin

Consensus / Discussion

Promote MHD R5 and Full-Text Search to “In development”

  • Proceed with MHD-R5 as a parallel line; R4 remains recommended.
  • Keep MHD-R5 scope limited (no net-new functionality beyond R5 alignment).
  • Prefer MHD-R5 branch + suffixed versioning to avoid confusion with the R4 line.
  • MHD-R5 Does not conflict with Full-Text Search
  • Scope Full-Text Search to MHD R4

Action Items

  1. John Moehrke: Set up the MHD-R5 branch and seed with the initial change list (DocumentReference diffs, AuditEvent approach, examples, and a cross-reference table).
  2. gematik participants (Michael Onken, Raik Kuhlisch) and interested parties: Provide EU/EHDS projectathon expectations and testing scenarios to guide scope and timing.
  3. Full-Text Search proponents: Draft initial option text for MHD actors and propose conformance test cases.
  4. Planning/Tech co-chairs: Define publication placement/labels so R5 is findable without implying replacement of R4.
