    Description

      US Core Medication request literally says: 

      MedicationRequest.dosageInstruction.text = (USCDI) Free text dosage instructions e.g. SIG

      So the free-text sig entryRelationship should map here.

       

      Meanwhile, the patientInstructions should come from the Instruction Activity. Currently this is mapped to .dosageInstruction.additionalInstruction - which, if the activity is coded, does seem to make sense. However, if the activity is just in text (via act.text; or act.code.originalText when code does not have any value), then .dosageInstruction.patientInstruction feels like a more appropriate place for this. In any case, again - this was not demonstrated by any vendors at connectathons, is not required by C-CDA, and is not mentioned in USCDI / US Core (unlike free-text sig), so perhaps this mapping should just be omitted for now.
