Topic: Example of Group for Patients with Condition
Geoff Low (May 26 2021 at 15:08):
Does anyone have an example of a Group where the inclusion is based on a patient condition - I found an example where CQL was used to gather Patients with the Condition, but I can't quite get the syntax right for adding that sort of statement into FSH

@Geoff Low -- if you can point us to the example you found, we might be able to help you formulate how to do it in FSH.

This is what I was looking at:

Thanks, @Geoff Low. I put that example on the right-hand-side of FSH Online and converted it to FSH and ended up with this:
Instance: example-group
InstanceOf: Group
Usage: #example
* type = #person
* actual = false
* characteristic.extension.url = "http://hl7.org/fhir/StructureDefinition/cqf-expression"
* characteristic.extension.valueExpression.language = #text/cql
* characteristic.extension.valueExpression.expression = "exists [Condition: Diabetes]"
* characteristic.exclude = false
You can also create extensions using a slightly different syntax like this:
Alias: CQFEXPRESSION = http://hl7.org/fhir/StructureDefinition/cqf-expression
Instance: example-group
InstanceOf: Group
Usage: #example
* type = #person
* actual = false
* characteristic.extension[CQFEXPRESSION].valueExpression.language = #text/cql
* characteristic.extension[CQFEXPRESSION].valueExpression.expression = "exists [Condition: Diabetes]"
* characteristic.exclude = false
