I'm trying to get a valueset to work in CQL. How can I troubleshoot, is there someway to see what valueset codes are available through a CQL statement? @Bryn Rhodes

You can issue an $expand against that valueset on the server.

Aslan Brooke (Oct 30 2018 at 01:54):

@Bryn Rhodes So $expand works fine: http://hapi.fhir.org/baseDstu3/ValueSet/368154/$expand
Here is the valueset: http://hapi.fhir.org/baseDstu3/ValueSet/368154
But when I try to use in CQL, I can't make sense of the write valueset statement:

valueset "Heart Failure" : 'https://ontoserver.csiro.au/stu3-latest/ValueSet/HeartFailure'
valueset "Heart Failure" : 'http://hapi.fhir.org/baseDstu3/ValueSet/368154'
valueset "Heart Failure" : 'http://hapi.fhir.org/baseDstu3/ValueSet/368154'
valueset "Heart Failure" : 'HeartFailure'

None of them seem to allow me filter the patient id=367771 by condition.
Using:

define "test" : [Condition : "Heart Failure"] C

Bryn Rhodes (Oct 30 2018 at 01:56):

So the first declaration is the right one because it's using the canonical URL for the value set.

Bryn Rhodes (Oct 30 2018 at 01:56):

Is that value set loaded on the same server that has the patient data?

Aslan Brooke (Oct 30 2018 at 01:57):

Yes.

Aslan Brooke (Oct 30 2018 at 01:57):

I copied the valueset over from the ontoserver tool: http://clinfhir.com/valuesetCreator.html

Aslan Brooke (Oct 30 2018 at 02:00):

The Patient/367771 on the hapi.fhir.org/baseDstu3 has a condition with:

  "code": {
    "coding": [
      {
        "system": "http://hl7.org/fhir/sid/icd-10",
        "code": "I50221",
        "display": "Systolic heart failure, chronic"
      }
    ]
  }

This code is in the valueset as seen in the expansion: http://hapi.fhir.org/baseDstu3/ValueSet/368154/$expand
