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

EHDSAllergyIntolerance to FHIR AllergyIntolerance Mapping

EHDSAllergyIntolerance → AllergyIntolerance
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.

EHDSAllergyIntolerance → AllergyIntolerance

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

Mapping Context

EHDSAllergyIntolerance → AllergyIntolerance
EHDSAllergyIntolerance (Logical Model) Relationship AllergyIntolerance
Element Description Relation Resource Element Description Notes
header Common header for all patient-related data. related-to AllergyIntolerance. General metadata. Dataset-level; not usually carried in AllergyIntolerance as-is.
header.subject Patient/subject this alert is about. equivalent AllergyIntolerancepatient Reference to the patient or subject of the allergy/intolerance.
header.identifier Business identifier for the object. equivalent AllergyIntoleranceidentifier Business identifier for this allergy. Copy over all identifiers if multiple.
header.author[x] Who created/issued the alert. equivalent AllergyIntolerancerecorder〔R4〕 Who recorded the sensitivity.
header.author[x] Who created/issued the alert. equivalent AllergyIntoleranceparticipant.actor〔R5〕 Who recorded the sensitivity. With participant.function = "http://terminology.hl7.org/CodeSystem/provenance-participant-type#author"
header.date Date and optionally time of authoring/issuing. equivalent AllergyIntolerancerecordedDate When the allergy/intolerance was recorded.
header.status Current status of the allergy or intolerance. equivalent AllergyIntoleranceclinicalStatus Clinical status of the allergy/intolerance. Map using the EHDS to HL7 allergy intolerance status value set alignment.
header.source Source of the information (e.g. patient, proxy). equivalent AllergyIntoleranceasserter〔R4〕 Source of the information about the allergy
header.source Source of the information (e.g. patient, proxy). equivalent AllergyIntoleranceparticipant.actor〔R5〕 Source of the information about the allergy With participant.function = "http://terminology.hl7.org/CodeSystem/provenance-participant-type#informant"
header.language Language of the resource (IETF tag). equivalent AllergyIntolerancelanguage Language used in the flag text.
agentOrAllergen A specific allergen or other agent/substance (drug, food, chemical agent, etc.) to which the patient has an adverse reaction propensity. equivalent AllergyIntolerancecode Concept that identifies the substance, product, or agent responsible. CodeableConcept. Bound in EHDS to eHDSI value sets; in FHIR usually VS: AllergyIntolerance Substance/Product.
note Additional information about the allergy or intolerance. source-is-broader-than-target AllergyIntolerancenote.text Additional narrative about the allergy/intolerance.
criticality Estimate of the potential clinical harm, or seriousness, of a reaction. equivalent AllergyIntolerancecriticality Estimate of potential clinical harm. ValueSets in EHDS reference eHDSICriticality; FHIR has its own required VS.
certainty Assertion about the certainty associated with the propensity (diagnostic/clinical evidence). equivalent AllergyIntoleranceverificationStatus Clinical verification status of the allergy/intolerance. EHDS name "certainty" ≈ FHIR "verificationStatus" (confirmed / refuted / unconfirmed).
onsetDate When the allergy or intolerance was identified. equivalent AllergyIntoleranceonset[x] When the allergy/intolerance was identified or first became relevant. FHIR supports multiple datatypes; here you have dateTime → map to onsetDateTime.
endDate Date of resolution of the allergy (when it was deemed no longer necessary to track). equivalent AllergyIntoleranceextension:abatement Date and/or time of the last known occurrence of a reaction.
reaction Adverse Reaction Events linked to exposure to substance. equivalent AllergyIntolerancereaction Details about each adverse reaction event. 0..* in both models.
reaction.agentOrAllergen Specific substance or pharmaceutical product considered to be responsible for the reaction event. equivalent AllergyIntolerancereaction.substance Specific substance or pharmaceutical product considered to be responsible for event. Maps the reaction-level causative agent where provided.
reaction.manifestation Description of the clinical manifestation of the allergic reaction (e.g. anaphylactic shock, angioedema). equivalent AllergyIntolerancereaction.manifestation Clinical symptoms and/or signs that are observed during the reaction. CodeableConcept; EHDS allows multiple; FHIR reaction.manifestation is 1..* CodeableConcept.
reaction.severity Severity of the clinical manifestation. equivalent AllergyIntolerancereaction.severity Mild / moderate / severe. FHIR has required VS; EHDS references eHDSISeverity.
reaction.onset Date of the observation of the reaction. equivalent AllergyIntolerancereaction.onset When the reaction occurred.
