MedicationRequest. For that reason, this mapping is based on the prescription model
realised by the HL7 Europe Medication Prescription and Dispense (MPD) FHIR Implementation
Guide (https://hl7.eu/fhir/mpd). This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR MedicationRequest profile used by this Implementation Guide.
| EHDSMedicationPrescription (Logical Model) | Relationship | MedicationRequest | ||
|---|---|---|---|---|
| Element | Relation | Resource | Element | Notes |
| header | related-to | MedicationRequest | . | Dataset-level information; not directly represented on the MedicationRequest instance. |
| header.subject | equivalent | MedicationRequest | subject | |
| header.identifier | source-is-narrower-than-target | MedicationRequest | identifier | |
| header.identifier | source-is-narrower-than-target | MedicationRequest | groupIdentifier | |
| header.author[x] | equivalent | MedicationRequest | requester | Reference to Practitioner / PractitionerRole / Organization depending on profile rules. |
| header.date | equivalent | MedicationRequest | authoredOn | |
| header.status | equivalent | MedicationRequest | status | Use statusReason when additional context is required. |
| header.language | equivalent | MedicationRequest | language | |
| header.statusReason[x] | equivalent | MedicationRequest | statusReason | The model allows for CodeableConcept and string. The target only CodeableConcept. |
| presentedForm | no-map | MedicationRequest | Reference a DocumentReference containing the rendered prescription. | |
| prescriptionItem | equivalent | MedicationRequest | . | Create one MedicationRequest per prescription item. |
| prescriptionItem.identifier | equivalent | MedicationRequest | identifier | |
| prescriptionItem.medication | equivalent | MedicationRequest | medication[x]〔R4〕 medication〔R5〕 |
|
| prescriptionItem.indication[x] | equivalent | MedicationRequest | reasonCode〔R4〕 reason.concept〔R5〕 |
|
| prescriptionItem.indication[x] | equivalent | MedicationRequest | reasonReference〔R4〕 reason.reference〔R5〕 |
Reference to Condition or other resource. |
| prescriptionItem.indication[x] | related-to | MedicationRequest | reasonCode.text | Alternatively capture as note if preferred. |
| prescriptionItem.intendedUseType | source-is-narrower-than-target | MedicationRequest | category | Use dedicated category code or custom extension if additional granularity is required. |
| prescriptionItem.periodOfUse | related-to | MedicationRequest | extension:effectiveDosePeriod〔R4〕 effectiveDosePeriod〔R5〕 |
|
| prescriptionItem.quantityPrescribed | equivalent | MedicationRequest | dispenseRequest.extension:prescribedQuantity | |
| prescriptionItem.validityPeriod | equivalent | MedicationRequest | dispenseRequest.validityPeriod | |
| prescriptionItem.dosageInstructions | equivalent | MedicationRequest | dosageInstruction | Map each EHDSDosaging entry to a dosageInstruction. |
| prescriptionItem.substitution | equivalent | MedicationRequest | substitution | |
| prescriptionItem.substitution.allowed[x] | equivalent | MedicationRequest | substitution.allowed[x]] | |
| prescriptionItem.substitution.reason[x] | equivalent | MedicationRequest | substitution.reason | FHIR accepts CodeableConcept; textual reasons may need an additional note. |
| prescriptionItem.status | equivalent | MedicationRequest | status | For single-item prescriptions, same meaning as header.status. |
| prescriptionItem.statusReason[x] | equivalent | MedicationRequest | statusReason | As above, textual-only reasons may require notes. |
| prescriptionItem.numberOfRepeats | equivalent | MedicationRequest | dispenseRequest.numberOfRepeatsAllowed | |
| prescriptionItem.minimumDispenseInterval | equivalent | MedicationRequest | dispenseRequest.dispenseInterval | |
| prescriptionItem.offLabel | related-to | MedicationRequest | extension:offLabelUse | |
| prescriptionItem.offLabel.isOffLabelUse | related-to | MedicationRequest | extension:offLabelUse | Implementer-specific extension required. |
| prescriptionItem.offLabel.reason[x] | related-to | MedicationRequest | extension:offLabelUse.reason | Same extension as above; allow CodeableConcept or string. |
| prescriptionItem.note | equivalent | MedicationRequest | note.text | Use note.author / note.time if available. |
