HL7 Europe Base and Core FHIR IG
2.0.0-recon - ci-build 150

HL7 Europe Base and Core FHIR IG, published by HL7 Europe. This guide is not an authorized publication; it is the continuous build for version 2.0.0-recon built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7-eu/base/ and changes regularly. See the Directory of published versions

EHDSCondition to FHIR Condition Mapping

EHDSCondition → Condition
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.

EHDSCondition → Condition

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

Mapping Context

EHDSCondition → Condition
EHDSCondition (Logical Model) Relationship Condition
Element Description Relation Resource Element Description Notes
header Common header for all patient-related data. related-to Condition . General metadata. Dataset-level; not usually carried in Condition as-is.
header.subject Patient/subject this condition is about. equivalent Condition subject Reference to the patient or subject of the condition. Reference to Patient (or other subject).
header.identifier Business identifier for the object. equivalent Condition identifier Business identifier for this condition. Copy over all identifiers if multiple.
header.author[x] Who created/issued the condition record. equivalent Condition recorder〔R4〕 Who recorded the condition. Condition has no generic "author"; use recorder in R4.
header.author[x] Who created/issued the condition record. equivalent Condition participant.actor〔R5〕 Who recorded the condition. Condition has no generic "author"; use participant.actor in R5.
header.date Date and optionally time of authoring/issuing. equivalent Condition recordedDate When the condition was recorded.
header.status Status of the condition/problem (e.g. active, resolved, inactive, etc). equivalent Condition clinicalStatus Current clinical status of the condition. FHIR has a required value set for clinicalStatus; EHDS references HL7 Condition Clinical Status Codes.
header.source Source of the information (e.g. patient, proxy). equivalent Condition asserter〔R4〕 Source of the information about the condition.
header.source Source of the information (e.g. patient, proxy). equivalent Condition participant.actor〔R5〕 Source of the information about the condition. With participant.function = "http://terminology.hl7.org/CodeSystem/provenance-participant-type#informant"
header.language Language of the resource (IETF tag). equivalent Condition language Language used in narrative/notes.
problem Code identifying the condition, problem or diagnosis. equivalent Condition code Identification of the condition, problem, or diagnosis. CodeableConcept. EHDS binds to ICD-10, SNOMED CT, ICD-O, Orphacode.
onsetDate Onset date of a problem/condition. equivalent Condition onsetDateTime Estimated or actual date/time the condition started. Map to onsetDateTime in FHIR.
endDate The date or estimated date that the condition resolved or went into remission. equivalent Condition abatementDateTime When the condition abated or went into remission. Use abatementDateTime; abatement may also be represented by clinicalStatus = resolved.
category Category or categories of the problem (e.g. POA, HAC, other categorisations). equivalent Condition category Problem category (e.g. problem-list-item, encounter-diagnosis). 0..* in both models; EHDS may use additional national/organisational codes.
resolutionCircumstances Reason for which the status changed from current to inactive (free text if not represented elsewhere). source-is-broader-than-target Condition note.text Additional text about the condition. FHIR Condition has no direct "resolution reason"; use Condition.note
severity Subjective assessment of the severity of the condition. equivalent Condition severity Clinical severity of the condition. CodeableConcept; HL7 / SNOMED CT value sets.
bodySite The anatomical location including laterality where this condition manifests itself. source-is-broader-than-target Condition bodySite Anatomical location(s) affected by the condition. EHDS uses EHDSBodyStructure; map to one or more Condition.bodySite. Use referenced BodyStructure if profiling for more detail.
bodySite The anatomical location including laterality where this condition manifests itself. equivalent Condition extension:bodySite Anatomical location(s) affected by the condition. EHDS uses EHDSBodyStructure; map to one or more Condition.bodySite. Use referenced BodyStructure if profiling for more detail.
stage Stage/grade usually assessed formally using a specific staging/grading system. Multiple assessment systems could be used. equivalent Condition stage Simple summary of condition stage. FHIR also has stage.assessment (Reference). For multiple staging systems, create multiple Condition.stage repetitions.
diagnosisAssertionStatus Assertion about the certainty associated with a diagnosis. equivalent Condition verificationStatus Whether the condition is unconfirmed, provisional, confirmed, refuted, etc. Both EHDS and FHIR refer to HL7 Condition Verification Status.
specialistContact Health Professional specifically related to the problem, as a preferred contact. source-is-narrower-than-target CareTeam note.text Who is involved FHIR Condition has no native participant element. Suggest to use Condition.note to record in a textual form who should be contacted. When used, this information can also be derived from the CareTeam involved for the care of this Condition (referred in CareTeam.reason).
externalResource External resource related to the problem (e.g. guidelines for a rare disease). source-is-narrower-than-target Condition extension:relatedArtifact Related artifacts such as additional documentation, justification, dependencies, bibliographic references, and predecessor and successor artifacts.
