ePrescription & eDispensation

Information Models

EHDS information models for ePrescription:

Components of a prescription and their representation as EHDS information models:

• Prescription: EHDSMedicationPrescription
• Patient: EHDSPatient
• Prescriber: EHDSHealthProfessional
• Medication: EHDSMedication
• Usage instructions: EHDSDosaging

EHDS information models for eDispensation:

• Dispense: EHDSMedicationDispense
• Patient: EHDSPatient
• Dispenser: EHDSHealthProfessional
• Medication: EHDSMedication
• Usage instructions: EHDSDosaging
• Location: EHDSLocation

Please note that dispense can only include one medication - therefore, in case of multi-line prescriptions, the dispense should reference the prescription item rather than just the full prescription.

Components of declining a dispense and their representation as EHDS information models:

• DispenseDecline: EHDSDispenseDecline
• Patient: EHDSPatient
• Dispenser: EHDSHealthProfessional

Dispense can be declined for the whole prescription or just for a prescription item.

FHIR Implementation Guide

FHIR Implementation Guide is being developed in a cross-project working group lead by HL7 Europe and IHE (see working group information). Business and data requirements defined in Xt-EHR Task 6.2 are discussed further in the working group in order to gather feedback from the implementers. Approved requirements are adopted by HL7 Europe MPD FHIR IG.

Ongoing work:

• R4 FHIR IG
• R5 FHIR IG

IHE Profile

FHIR-based IHE profile for this use case is in draft status, please see IHE Medication Prescription and Delivery profile for more information.

IHE Profile has a global scope and is not part of Xt-EHR deliverable. However, the HL7 Europe / IHE joint working group (see above) allows mutually beneficial cooperation and early alignment.
