# EHDSPregnancyHistory -> Pregnancy Outcome Observation

**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.

### EHDSPregnancyHistory -> Pregnancy Outcome Observation

 This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR pregnancy outcome Observation profile used by this Implementation Guide. 

**Mapping Context**
*  **Source logical model:** [ EHDSPregnancyHistory ](https://www.xt-ehr.eu/fhir/models/StructureDefinition-EHDSPregnancyHistory.html) 
*  **Target FHIR profile:** [ ObservationPregnancyOutcomeEuEps ](StructureDefinition-observation-pregnancy-outcome-eu-eps.md)

| header.subject | Patient/subject this pregnancy data is about. | equivalent | Observation | subject | Reference to the patient or subject of the observation. |  |
| header.identifier | Business identifier for the object. | equivalent | Observation | identifier | Business identifier for this observation. |  |
| header.author[x] | Author of this observation. | related-to | Observation | performer | Who is responsible for the observation. |  |
| header.date | Date and time of authoring/issuing. | equivalent | Observation | issued | When the observation result was issued. |  |
| header.status | Status of this observation. | equivalent | Observation | status | Registered | preliminary | final | amended | ... |  |
| header.source | Source of information (e.g. patient, patient's proxy). | related-to | Observation | note | Additional context about information provenance. | Observation has no direct informationSource element. Here proposed to use note element to carry source information. |
