## Prespcription and Medication Models Overview

MyHealth@EU logical models for ePrescription and eDispensation refine the EHDS logical information models provided by the Xt-EHR project. These models use obligations on the logical models to highlight the elements identified by the MyHealth@EU Functional Requirements. Three types of obligations are defined based on the MyHealth@EU requirements:

- Mandatory: the data element must be provided
- Required: the data element must be provided, although exceptional justifications can be provided
- Optional: the data element can be completely omitted

These obligations are implemented using the following rule sets:

- `ObligationMandatory` - SHALL:handle for mandatory elements
- `ObligationRequired` - SHOULD:handle for required elements
- `ObligationOptional` - MAY:able-to-populate for optional elements

### Information Models

#### ePrescription

ePrescription information is communicated using the MyHealthEuMedicationPrescription model. This model extends the EHDS Medication Prescription model and is specifically designed for the MyHealth@EU ePrescription context.

The ePrescription model references supporting information models for the patient, prescriber, medication and dosage instructions.

#### eDispensation

eDispensation information is communicated using the MyHealthEuMedicationDispense model. This model extends the EHDS Medication Dispense model and is specifically designed for the MyHealth@EU eDispensation context.

The eDispensation model references supporting information models for the patient, dispenser, medication, dosage instructions and location.

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