# EHDSDeviceUse -> DeviceUseStatementEuEps

**Ongoing alignment:**The models are expected to continue evolving, with updates incorporated into this Implementation Guide to maintain alignment with the EHDS Implementing Acts.

**Yellow row/cells:**In this ballot publication, some row/cells of the mapping table have been left in yellow to indicate areas requiring further review or refinement; including feedback from the Xt-EHR joint action (see note above). These highlights will be addressed in subsequent updates to ensure accuracy and completeness of the mappings.

### EHDSDeviceUse -> DeviceUseStatementEuEps

 This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR DeviceUseStatementEuEps profile or type used by this Implementation Guide. 

**Mapping Context**
*  **Source logical model:** [ EHDSDeviceUse ](https://www.xt-ehr.eu/fhir/models/StructureDefinition-EHDSDeviceUse.html) 
*  **Target FHIR profile:** [ DeviceUseStatementEuEps ](StructureDefinition-deviceUseStatement-eu-eps.md)

| Element | Relation | Resource | Element | Notes |
| header | related-to | DeviceUseStatement | . | Dataset-level; not usually carried in DeviceUseStatement as-is. |
| header.subject | equivalent | DeviceUseStatement | subject | Reference to Patient (or other subject). |
| header.identifier | equivalent | DeviceUseStatement | identifier | Copy over all identifiers if multiple. |
| header.author[x] | no-map | DeviceUseStatement |  |  |
| header.date | equivalent | DeviceUseStatement | recordedOn |  |
| header.status | equivalent | DeviceUseStatement | status | Preferred binding: HL7 Device Use Statement Status or HL7 Device Usage Status. |
| header.source | related-to | DeviceUseStatement | source | When both header.author[x] and header.source are populated, additional profiling may be needed to preserve both semantics. |
| header.language | equivalent | DeviceUseStatement | language |  |
| periodOfUse | equivalent | DeviceUseStatement | timingPeriod |  |
| device[x] | source-is-broader-than-target | DeviceUseStatement | device | FHIR uses Reference(Device); CodeableConcept may require a Device instance. |
| bodySite | related-to | DeviceUseStatement | bodySite | EHDSBodyStructure may need to be summarized as CodeableConcept. |
| reason[x] | source-is-broader-than-target | DeviceUseStatement | reasonCode | FHIR uses CodeableConcept; references may need to be represented as codes or extensions. |
| note | equivalent | DeviceUseStatement | note |  |
