we need to capture a Patient’s healthcare literacy for a specific use case. While we capture this in an App via Questionnaire and QuestionnaireResponse, the post processing in the backend should turn the QuestionnaireResponse into a FHIR conformant structure.

I have been looking fort and back through all resources to see if there is something we could use, but resources like Observation seem to be ill-suited. Thus am torn between:

• an extension to the Patient
• using a custom tag on Patient
• the use of Basic with an appropriate extension
• potentially use Flag and our own internal CodeSystem

I am leaning towards Basic or Flag, even the tag sounds not too bad, but has any of you encountered a similar situation, and can share some ideas how you have solved it within the conformance boundaries?
