Hi-
Just as we capture String or other valueTypes outputs in PlanDefinition>action>dynamicValue>expression on CQL execution, can we capture FHIR resource(s) also if CQL returns a FHIR resource? I couldn't find a location or supporting valueType for PlanDefinition>action>dynamicValue. Please suggest.

@Bryn Rhodes (Also - not clear how this question relates to CDS Hooks?)

@Lloyd McKenzie : We, in turn, looking for a possibility to capture and send this response to CDSResonse via RequestGroup, when the request to trigger PlanDefinition/Related CQL came via CDSHooks request.

Hi Pankaj, yes, you can return any value from a CQL expression, and so you can have the expression in a dynamicValue return a FHIR resource. For a dynamicValue, it just has to be a value of the type (or implicitly convertible to the type) of the element identified by the path in the dynamicValue.

Thanks, @Bryn Rhodes for your inputs and suggestions. Can you give me an example of dynamic value/ action having dynamic values, where dynamic value(s) path(s) expect value from an expression of valuetype other than primitive(or implicitly convertible type(s))? Neither I could find any not have it running based on the valueType(s) or path(s) that I'm providing currrently. I would be really helpful to understand how API helps to capture different valueType(s) and a variety of valuetype(s) a CQL expression can return.
