HL7 Europe Base and Core FHIR IG, published by HL7 Europe. This guide is not an authorized publication; it is the continuous build for version 0.2.0-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7-eu/base-r5/ and changes regularly. See the Directory of published versions

EHDSMedication → Medication

This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR MedicationEuCore and OrganizationEuCore profiles used by this Implementation Guide.

Mapping Context

Source logical model: EHDSMedication
Target FHIR profiles: MedicationEuCore , OrganizationEuCore

The model supports prescribed/dispensed medication and can represent both generic (virtual) products and branded (real) products.

identifyingCodeCodeableConcept	Identifier or code for the product (virtual/branded/package).	equivalent	Medication	code	Code that identifies this medication.
identifyingCodeIdentifier	Identifier for the product (virtual/branded/package).	equivalent	Medication	identifier	Business identifiers for the medication entry.	Use multiple identifiers if needed; avoid conflicting meanings.
classification	Classification (e.g. ATC; narcotic/psychotropic; orphan drug).	equivalent	Medication	extension:classification	Classifications of the product, e.g ATC, narcotic/psychotropic, orphan drug, etc

packSize	Overall amount of product in one package.	related-to	Medication	amount〔R4〕	Amount of the medication in the package.	R4 `amount` is a Ratio; in R5 `totalVolume`.
packSize	Overall amount of product in one package.	related-to	Medication	totalVolume 〔R5〕	When the specified product code does not infer a package size, this is the specific amount of drug in the product.	R4 `amount` is a Ratio; in R5 `totalVolume`
item	A medication item (components in a combination pack).	equivalent	Medication	ingredient.item	A particular constituent of interest in the product.	An item - included in a product - is represented by a Medication resource referenced by the `ingredient.item` (see the example at https://hl7.eu/fhir/mpd-r5/Medication-02A-ClotrimazoleCanifugCremolum.html).

item.ingredient.strengthInfo.strength	Strength of the substance.	equivalent	Medication	ingredient.strengthRatio	Quantity of ingredient present.	Replicate per-item ingredients into`ingredient`. See note above about item
item.ingredient.strengthInfo.basisOfStrengthSubstance	Substance the strength refers to (if different).	equivalent	Medication	ingredient.strength[x].extension:basisOfStrengthSubstance	Substance the strength refers to (if different).	Replicate per-item ingredients into`ingredient`. See note above about item
item.unitOfPresentation	Unit of presentation for the manufactured item.	equivalent	Medication	extension:unitOfPresentation	Unit of presentation	See note above about item
item.containedQuantity	Quantity for liquids (e.g., 3ml / 1 vial).	equivalent	Medication	extension:sizeOfItem	Size of one item (for example, in a pack of 5 vials, this would represent the size of 1 vial).	See note above about item
