Agenda

• Discuss proposed solutions on issues #64 and #65 as sent out on Jan 14

Minutes

• Up-to-date list of issues can be consulted here
• Issue 64 : proposed solution:
• José discussed with other colleagues and here’s the proposed solution:

https://chat.fhir.org/#narrow/stream/179256-Orders-and.20Observation.20WG/topic/Observation.20comments

• We can have a data type CodedAnnotation which is an extension from the Annotation. From then on, we can add “tags” to any of these annotations, wherever we use them. I made the commit to show the solution – here’s the drill-down:

• The Observation.note is no longer an Annotation but the new data type called BeCodedAnnotation

https://build.fhir.org/ig/hl7-be/hl7-be-fhir-laboratory-report/branches/issue-64/StructureDefinition-be-observation-laboratory.html#tabs-diff

• This BeCodedAnnotation is the same as Annotation but appended an extension called annotation-code

https://build.fhir.org/ig/hl7-be/hl7-be-fhir-laboratory-report/branches/issue-64/StructureDefinition-coded-annotation.html#tabs-diff

• The annotation-code is an extension defined as having a CodeableConcept

https://build.fhir.org/ig/hl7-be/hl7-be-fhir-laboratory-report/branches/issue-64/StructureDefinition-annotation-code.html#tabs-diff

• This is bound by a valueset - we need to define the values for those tags. We can do it anytime soon (or leave as is, because the binding is not required).

https://build.fhir.org/ig/hl7-be/hl7-be-fhir-laboratory-report/branches/issue-64/ValueSet-be-vs-coded-annotation-types.html

• Issue 65 : proposed solution:
• The solution is simple after we have issue 64 resolved: We simply use the CodedAnnotation in the ReferenceRange (as an extension).

So we extend the element Observation.referenceRange to include an extension named BeReferenceRangeComment, which simply adds an element of type codedAnnotation to referenceRange
