## HDR Models Overview

MyHealth@EU logical models ([MyHealth@EU Hospital Discharge Report Content](https://webgate.ec.europa.eu/fpfis/wikis/x/uIe6ZQ)) 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

#### Hospital Discharge Report

The hospital discharge report is structured using the [MyHealthEuHdrDischargeReport model](StructureDefinition-MyHealthEuHdrDischargeReport.md) which is divided into a document header, a structured body with multiple clinical sections, and optional attachments.

The body of the report covers the following clinical sections:

* **Alerts** – allergies, intolerances and medical alerts relevant to the hospital stay
* **Encounter information** – details of the inpatient encounter including admission and discharge
* **Admission evaluation** – objective findings and functional status at admission (if relevant)
* **Patient history** – past problems, devices, and procedures relevant to the current episode
* **Course of encounter** – diagnostic summary, significant procedures, devices, pharmacotherapy, and test results during hospitalisation
* **Discharge details** – objective findings and functional status at discharge
* **Medication summary** – medication recommended after discharge
* **Care plan** – care plan and other recommendations after discharge

#### Encounter

The encounter is described using the [MyHealthEuHdrEncounter model](StructureDefinition-MyHealthEuHdrEncounter.md), capturing admission and discharge details, service provider, reason for admission, and locations visited during the stay.

#### Clinical Content Models

Clinical content within the report body is described by the following models:

* [MyHealthEuHdrCondition](StructureDefinition-MyHealthEuHdrCondition.md) – problems, diagnoses, and conditions
* [MyHealthEuHdrObservation](StructureDefinition-MyHealthEuHdrObservation.md) – clinical observations including vital signs and anthropometric measurements
* [MyHealthEuHdrProcedure](StructureDefinition-MyHealthEuHdrProcedure.md) – significant procedures performed during hospitalisation
* [MyHealthEuHdrDeviceUse](StructureDefinition-MyHealthEuHdrDeviceUse.md) – medical devices and implants
* [MyHealthEuHdrMedicationUse](StructureDefinition-MyHealthEuHdrMedicationUse.md) – medication use during and after hospitalisation
* [MyHealthEuHdrCarePlan](StructureDefinition-MyHealthEuHdrCarePlan.md) – care plan after discharge
* [MyHealthEuHdrAllergyIntolerance](StructureDefinition-MyHealthEuHdrAllergyIntolerance.md) – allergies and intolerances
* [MyHealthEuHdrAlert](StructureDefinition-MyHealthEuHdrAlert.md) – medical alerts
