Topic: Validation error - MedicationStatement.medication[x] slice

Rob Eastwood (Jun 03 2019 at 01:45):

The HL7 Australia profile for MedicationStatement has a slice on the medication[x] element to define a slice for the 2 choice types - ie if supplying as a CodeableConcept then do it this way, or if supplying a reference, do it this other way.
As the medication[x] element is 1..1 in the base resource, when the IG publisher builds the profile, both of the slices get a corresponding 1..1 - which is not the design intent. The intent is to have either of the choices, not both.

When examples are created to comply with this profile (using a meta.profile value) with the intent to supply just one of the medication[x] choices , the following errors are generated in the QA report:

Profile http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/medicationstatement-summary-1, Element 'MedicationStatement.medicationCodeableConcept[medicationCoded]': minimum required = 1, but only found 0
Profile http://ns.electronichealth.net.au/ci/fhir/3.0/StructureDefinition/medicationstatement-summary-1, Element 'MedicationStatement.medicationReference[medicationReference]': minimum required = 1, but only found 0

Note that we are using a profile derived from the above HL7 AU profile that only adds a must support on this element.
The MedicationStatement example supplies this content (among other bits left out for brevity):

<medicationCodeableConcept>
        <coding>
            <system value="http://snomed.info/sct"/>
            <code value="23358011000036102"/>
            <display value="metformin hydrochloride 500 mg tablet"/>
        </coding>
        <text value="Metformin 500mg"/>
</medicationCodeableConcept>

Q: is this a problem with the profile somewhere or something in the validation process?

sounds like a problem in the snapshot generation in the ig pbulisher - this is in au base?

@Grahame Grieve - yes that is correct; AU Base MedicationStatement here http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-medicationstatement.html
thank you

well, this is another case of slicing a non-repeating element. We have a methodology failure here - sharp disagreement in the team, which we are discussing at DevDays next week

Thanks @Grahame Grieve
