This profile was generated from HL7 StructureDefinition on 2019-03-28 and constrained during a review of US Core against Canadian sources. RxNorm is not used in Canada and the list of medicinal products available differs from the US, therefore PrescribeIT Medication Profile was used as a basis for this profile - with some significant differences due to structural differences between versions of FHIR.

Key differences from USCoreR4 Medication:

• RxNorm is not used in Canada, replaced with a Canadian list of MedicationForm

Key differences from PrescribeIT Medication Profile:

• Medication.id left with FHIR defaults
• Medication.product element has been deleted from FHIR, used Medication.form, Medication.ingredient, Medication.amount instead of equiv. elements in Medication.product

Note:

• medicationStrength, isRepresentative, and isActive extensions socialized in this profile and come from the PrescribeIT 2.0 specification
• Medication.ingredient.item[x] is currently restricted in a manner consistent with the PrescribeIT Medication profile. « Question for Implementors: Is this preferable to providing references to other Medication (and potentially Substance) resources?
• ON DHDR and HL7 v3 AdministerableMedicine appear to approach similar things differently than below.

• Differential Table
• Key Elements Table
• Snapshot Table
