MyHealth@EU refined model for allergy or intolerance

Basic metadata for this information

Patient/subject information

Business identifier for the object, unique within its system. Supporting disambiguation between different contexts (systems/countries).

The author of the allergy/intolerance information.

Date and optionally time of authoring/issuing

Current status of the allergy or intolerance, for example, whether it is active, in remission, resolved, etc.

HL7 allergy intolerance status

eHN PS Guideline, MyHealth@EU, ISO IPS

Source of information (e.g. patient, patient's proxy). Used in case the patient has authored the information or the author has submitted patient-stated information.

Language in which the resource is written. Language is expressed by the IETF language tag.

BCP 47

Code for an allergy or intolerance statement (either a positive or a negated/excluded statement). This may be a code for a substance or pharmaceutical product that is considered to be responsible for the adverse reaction risk (e.g., "Latex"), an allergy or intolerance condition (e.g., "Latex allergy"), or a negated/excluded code for a specific substance or class (e.g., "No latex allergy") It must be clinically safe to only process the 'code' and ignore the 'reaction.substance'.

ATC, EMA SPOR SMS, SNOMED CT

eHN PS Guideline, MyHealth@EU, ISO IPS

Additional information about the allergy or intolerance

eHN PS Guideline, ISO IPS

Estimate of the potential clinical harm, or seriousness, of a reaction to an identified substance.

HL7 allergy intolerance criticality

eHN PS Guideline, MyHealth@EU, ISO IPS

Assertion about the certainty associated with a propensity, or potential risk, of a reaction to the identified substance. Diagnostic and /or clinical evidence of condition

HL7 allergy intolerance verification

eHN PS Guideline, MyHealth@EU, ISO IPS

When allergy or intolerance was identified

MyHealth@EU, ISO IPS

Date of resolution of the allergy (e.g. when the clinician deemed there is no longer any need to track the underlying condition)

eHN PS Guideline, MyHealth@EU, ISO IPS

Adverse reaction events linked to exposure to substance.

ISO IPS (explicit), implicitly in eHN PS Guideline, MH@EU

Identification of the specific substance (or pharmaceutical product) considered to be responsible for the Adverse Reaction event. Note: the substance for a specific reaction may be different from the substance identified as the cause of the risk, but it must be consistent with it.
It must be clinically safe to only process the 'code' and ignore the 'reaction.substance'.

Description of the clinical manifestation of the allergic reaction. Example: anaphylactic shock, angioedema. (the clinical manifestation also gives information about the severity of the observed reaction).

ICD-10, SNOMED CT

The element is present in eHN PS GL, MyHealth@EU specifications and ISO IPS. Element name and description is taken from eHN PS GL. Cardinality in MyHealth@EU for this element, used here, is one manifestation per severity and onset, while the cardinality in FHIR IPS IG allows multiple manifestations per severity and onset.

Severity of the clinical manifestation of the allergic reaction.

SNOMED CT, HL7 reaction event severity

The element is present in eHN PS GL, MyHealth@EU specifications and ISO IPS. Element name and description is taken from eHN PS GL.

Date and time of the onset of the reaction

The element is present in eHN PS GL. Element name and description is taken from eHN PS GL.
