Allergy / Intolerance information model

The person that has the allergy

The substance - from a lst of substances - that the person is allergic to. It is possible to use free text but for the products indicated, a code must be used

The category of the risk (food, medication, environment, biological,...). This information will not be encoded by the Recorder but can automatically be added using the SNOMED-CT code from causative agent

the type of risk (allergy, intolerance...). When it is not possible to distinguish between a real allergy, a non-allergic hypersensitivity or an intolerance you can use the 'Intolerance' type, but code the VerificationStatus as 'Unconfirmed'

The status of the allergy

The status of the allergy - if it is active or resolved

The verification status of the allergy - if it is confirmed or suspected or refuted

when the allergy/intolerance was recorded

Who recorded the allergy

Is the person at the source of the information (eg the patient, the general practitioner, a family member, the healthcare professional who registers the information himself, ...). He is represented as much as possible by a unique identification number, namely the national register number (INSZ) or the BIS number. However, when it comes to a parent or family member, only the role (e.g. father, mother, neighbor, caregiver, friend, etc.) is coded to meet the requirements of the GDPR.

Additional text note about the allergy or intolerance

known past reactions to the allergen

How the reaction manifested itself, e.g. rash, breathing difficulty...

For each manifestation it is possible to specify an actual date or approximate date (age, period, interval, ...) of each suspected manifestation of the risk

The status of the allergy

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
