description: This profile defines a set of constraints to the FHIR AllergyIntolerance resource for use in Ontario Patient Summaries (PS-ON). It refines constraints applied to the AllergyIntollerance resource by the PS-CA project, which is informed by the constraints of the [AllergyIntolerance-UV-IPS profile](http://hl7.org/fhir/uv/ips/StructureDefinition-AllergyIntolerance-uv-ips.html) and the [Canadian Baseline Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-allergyintolerance.html) to allow for cross-border and cross-jurisdiction sharing of Allergies and Intolerances. It documents the relevant allergies or intolerances (conditions) for a patient, describing the kind of reaction (e.g. rash, anaphylaxis,..); preferably the agents that cause it; and optionally the criticality and the certainty of the allergy. package_name: ca.on.oh-setp derivation: constraint name: AllergyIntolerancePSON type: AllergyIntolerance elements: patient: type: Reference mustSupport: true refers: ['http://ontariohealth.ca/fhir/StructureDefinition/ca-on-ps-profile-patient'] index: 20 elements: reference: {mustSupport: true, index: 21} required: [reference] onset: mustSupport: true choices: [onsetDateTime, onsetAge, onsetPeriod, onsetRange, onsetString] index: 23 criticality: {mustSupport: false, index: 9} clinicalStatus: {mustSupport: true, index: 4} meta: mustSupport: true index: 0 elements: profile: {mustSupport: true, index: 1} required: [profile] onsetRange: {type: Range, mustSupport: true, choiceOf: onset, index: 27} onsetAge: {type: Age, mustSupport: true, choiceOf: onset, index: 25} onsetPeriod: {type: Period, mustSupport: true, choiceOf: onset, index: 26} type: {mustSupport: true, index: 8} extension: type: Extension short: Abatement datetime url: http://hl7.org/fhir/uv/ips/StructureDefinition/abatement-dateTime-uv-ips index: 2 slicing: slices: abatement-datetime: match: {} schema: type: Extension short: Abatement datetime url: http://hl7.org/fhir/uv/ips/StructureDefinition/abatement-dateTime-uv-ips index: 2 elements: url: pattern: {type: uri, value: 'http://hl7.org/fhir/uv/ips/StructureDefinition/abatement-dateTime-uv-ips'} type: uri index: 3 onsetString: {type: string, mustSupport: true, choiceOf: onset, index: 28} code: type: CodeableConcept short: Concept -
