## EHDS Travel History Map

EHDSTravelHistory -> ObservationTravelEuEps
Ongoing alignment: The Xt-EHR logical models are under active revision and continuous refinement. Updates from Xt-EHR will be progressively incorporated into this Implementation Guide to maintain alignment with the evolving EHDS specifications.
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.

### EHDSTravelHistory -> ObservationTravelEuEps

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

Mapping Context

- Source logical model: EHDSTravelHistory
- ​ Target FHIR profile: ObservationTravelEuEps

EHDSTravelHistory -> ObservationTravelEuEps
EHDSTravelHistory (Logical Model) | Relationship | ObservationTravelEuEps
--- | --- | ---
Element | Description | Relation | Resource | Element | Description | Notes
header | Common header for all patient-related data. | related-to | Observation | . | General metadata. | Dataset-level; not usually carried in Observation as-is.
header.subject | Patient/subject this travel history is about. | equivalent | Observation | subject | Reference to the patient or subject of the observation. | Reference to PatientEuEps.
header.identifier | Business identifier for the object. | equivalent | Observation | identifier | Business identifier for this observation. | Copy over all identifiers if multiple.
header.authorship | Resource authoring details. | no-map | Observation | . | Observation lacks a dedicated recorder. Only when the observation result was issued can be represented. |
header.authorship.author[x] | Author(s) who issued the resource. | no-map | Observation |  | Observation lacks a dedicated recorder. |
header.authorship.datetime | Date and time of authoring/issuing. | equivalent | Observation | issued | When the observation result was issued. | 1.. in the model 0.. in the profile.
header.lastUpdate | Last technical correction/update. | source-is-broader-than-target | Observation | meta.lastUpdated | When the resource version last changed. | Use only when the timestamp reflects resource update (instant).
header.status | Status of the resource. | equivalent | Observation | status | Registered | preliminary | final | amended | ... | EHDS uses CodeableConcept; Observation.status is a required code. Align to HL7 ObservationStatus.
header.statusReason[x] | Reason for the current status. | no-map | Observation | - |  | No core element; use an extension if the status rationale is required.
header.language | Language of the resource (IETF tag). | equivalent | Observation | language | Language used in the observation. |
country | Country visited. | equivalent | Observation | valueCodeableConcept | Country visited. | Preferred binding: ISO 3166-1-2.
period | Date of entry and departure. | equivalent | Observation | effectivePeriod | Period of visit. |
