## ePrescription

### Information Models

#### Conceptual view

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

- Prescription: EHDSMedicationPrescription
- Patient: EHDSPatient
- Prescriber: EHDSHealthProfessional
- Medication: EHDSMedication
- Usage instructions: EHDSDosage

### 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.

### IHE Profile

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