Adapt IHE profiles for the Trace Context support

[qligier]

For us to support the Tracecontext header value in audit events, we need to adapt two IHE profiles:

BALP

We need to add the Tracecontext code to CodeSystem/BasicAuditEntityType and ValueSet/BasicAuditEntityTypesVS, and adapt the profiles. It is reported in IHE/ITI.BasicAudit#94 and done in IHE/ITI.BasicAudit#100.

MHD

In StructureDefinition/IHE.MHD.ProvideBundle.Audit.Recipient and StructureDefinition/IHE.MHD.ProvideBundle.Audit.Source, the AuditEvent.entity slice is closed and does not contain entity:transaction. This is reported in IHE/ITI.MHD#220.

In other profiles, the AuditEvent.entity slice is open, but the entity:transaction (when present) is restricted to XRequestId. We may want to ensure the slice is present everywhere, and that it allows the Tracecontext code.

Two known errors time of publication

This element does not match any known slice defined in the profile https://profiles.ihe.net/ITI/MHD/StructureDefinition/IHE.MHD.ProvideBundle.Audit.Source|4.2.1 and slicing is CLOSED: AuditEvent.entity[2]: Does not match slice 'patient' (discriminator: type.where((system = 'http://terminology.hl7.org/CodeSystem/audit-entity-type') and (code = '1') and (display = 'Person')).exists()), AuditEvent.entity[2]: Does not match slice 'submissionSet' (discriminator: type.where((system = 'http://terminology.hl7.org/CodeSystem/audit-entity-type') and (code = '2') and (display = 'System Object')).exists())
AuditEvent.entity: max allowed = 2, but found 3 (from https://profiles.ihe.net/ITI/MHD/StructureDefinition/IHE.MHD.ProvideBundle.Audit.Source|4.2.1)

This will be resolved as soon as an updated BALP, MHD are published

• check that it is tracked on the next cp call: Add support for Trace-Context IHE/ITI.BasicAudit#100
• check state of BALP for issue: Specify tracing identifiers in AuditEvents IHE/ITI.BasicAudit#94

[oliveregger]

7.5: corrected in IHE MHD, will be fixed with the next publication of MHD which is targeted in a few weeks.

AG Steuerung Weiterentwicklung rejected the extension of the W3C Trace Context in the EPR on October 24, 2024.
That means, the elaborated solution for the ordinance and the ATC and EPR FHIR IG cannot be integrated in release 2025.
