## EHDSMedicationUse to FHIR MedicationStatement Mapping

EHDSMedicationUse → MedicationStatementEuCore

### EHDSMedicationUse → MedicationStatementEuCore

This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR MedicationStatement profile used by this Implementation Guide.

Mapping Context

- Source logical model: EHDSMedicationUse
- Target FHIR profile: MedicationStatementEuCore

EHDSMedicationUse → MedicationStatementEuCore
EHDSMedicationUse (Logical Model) | Relationship | MedicationStatementEuCore
--- | --- | ---
Element | Relation | Resource | Element | Notes
header | related-to | MedicationStatement | . | Dataset-level; not usually carried in MedicationStatement as-is.
header.subject | equivalent | MedicationStatement | subject |
header.identifier | equivalent | MedicationStatement | identifier | Copy over all identifiers if multiple.
header.author[x] | no-map | MedicationStatement |  | If with author is intended the source of information, use the `informationSource` element.
header.date | equivalent | MedicationStatement | dateAsserted |
header.status | equivalent | MedicationStatement | status |
header.source | equivalent | MedicationStatement | informationSource |
header.language | equivalent | MedicationStatement | language |
treatmentStatus | equivalent | MedicationStatement | extension:adherence.code〔R4〕 adherence.code〔R5〕 |
medication | equivalent | MedicationStatement | medication[x] 〔R4〕 medication〔R5〕 | In the model only the Reference to `Medication`.
changeType | no-map | MedicationStatement |  | No native element in MedicationStatement to record the change type ('added', 'removed', 'altered') within a medication summary; consider an extension if needed.
reason[x] | equivalent | MedicationStatement | reasonCode 〔R4〕 reason.concept〔R5〕 |
dosageInstructions | equivalent | MedicationStatement | dosage | Map each EHDSDosaging row to a `dosage` element.
periodOfUse | equivalent | MedicationStatement | effectivePeriod |
derivedFrom[x] | equivalent | MedicationStatement | derivedFrom |
note | source-is-broader-than-target | MedicationStatement | note.text |
