See Comparison with other national and international IGs for a comparison between AU Core profiles and profiles in other implementation guides.

Usage Scenarios

The following are supported usage scenarios for this profile:

• Query for a patient's allergies/adverse reactions
• Record or update a patient's allergies/adverse reactions

Profile Specific Implementation Guidance

• To represent that a patient does not have an allergy or category of allergies, an appropriate negation code (e.g. 716186003 |No known allergy| or 1003774007 |No known Hevea brasiliensis latex allergy|) is used in AllergyIntolerance.code
• The use of coding can vary significantly across systems, requesters need to understand that they may encounter codes they do not recognise and be prepared to handle those resources appropriately. Responders SHOULD populate AllergyIntolerance.code.text and/or AllergyIntolerance.code.coding.display so that requesters can at least display the condition even if the requester does not recognise the code supplied.
• Refutation is not expected to be handled except as above - an appropriate negation code in AllergyIntolerance.code and AllergyIntolerance.verificationStatus of "confirmed" or "unconfirmed"
• Where only substance is known (e.g. 111088007 |Latex|) and not a statement of allergy or intolerance (e.g. 1003755004 |Allergy to latex|), the substance is sent in AllergyIntolerance.code

Summary

Mandatory: 1 element
Must-Support: 9 elements

Structures

This structure refers to these other structures:

• AU Core Patient (http://hl7.org.au/fhir/core/StructureDefinition/au-core-patient)

Maturity: 2

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the AU Core CapabilityStatements for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described here and the syntax used to describe AU Core interactions is defined here.

Any search parameter defined in FHIR may be 'allowed' by the system unless explicitly marked as "SHALL NOT". A few items are marked as MAY in this implementation guide to highlight their potential relevance.

Mandatory Search Parameters

The following search parameters and search parameter combinations SHALL be supported:

1. SHALL support searching using the patient search parameter:
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

   GET [base]/AllergyIntolerance?patient={Type/}[id] or optionally GET [base]/AllergyIntolerance?patient.identifier=[system|][code]

   Example:

   1. GET [base]/AllergyIntolerance?patient=5678
   2. GET [base]/AllergyIntolerance?patient.identifier=http://ns.electronichealth.net.au/id/medicare-number|32788511952
   3. GET [base]/AllergyIntolerance?patient.identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608833357361

   Implementation Notes: Fetches a bundle of all AllergyIntolerance resources for the specified patient (how to search by reference and how to search by token)

Optional Search Parameters

The following search parameters and search parameter combinations SHOULD be supported:

1. SHOULD support searching using the combination of the patient and clinical-status search parameters:
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

   GET [base]/AllergyIntolerance?patient={Type/}[id]&clinical-status={system|}[code]{,{system|}[code],...}

   Example:

   1. GET [base]/AllergyIntolerance?patient=5678&clinical-status=http://terminology.hl7.org/CodeSystem/allergyintolerance-clinical|active

   Implementation Notes: Fetches a bundle of all AllergyIntolerance resources for the specified patient and status (how to search by reference and how to search by token)
