Please note: This guidance has been superseded by the Implementation guide for digitial medicines, which contains up-to-date information.
Element: dosageInstruction
It is recommended this element is required for an MVP implementation.
An example instance where this could be used is if a substitution has taken place where the dosage instruction differs to the one in the MedicationRequest.
If the dosageInstruction element is used then it should be represented as a structured dose where possible in the event that the receiving system is required to interpret the content.
In this instance, population of just the dosageInstruction.text element would be unacceptable for a successful implementation.
Refer to FHIR Dose Syntax Implementation Guidance (or any subsequent version) for guidance.
