Topic: application/x-fhir-query in calculatedExpression?
Paul Lynch (Dec 10 2018 at 20:43):
Does it make any sense to support Expressions of type application/x-fhir-query in questionnaire-calculatedExpression? The comment for that extension says, "Calculated value is updated as other answers in the QuestionnaireResponse are filled in"-- which I would think would only need to be done if the Expression were of type FHIRPath (or I suppose CQL). If one wanted to run a FHIR query, I would think that would be via the questionnaire-initialExpression extension.

It could if the item was of type Reference - in that case the query could resolve to the resource(s) that would be the initial answers.

How would that differ from initialExpression?

Where are you seeing calculatedExpression? I don't think it exists...

It got moved to SDC in the most recent draft.
Paul Lynch (Dec 11 2018 at 16:11):
Perhaps moving it made it harder to find?

When we end up with a central registry...
