This structure is derived from AUCoreAllergyIntolerance

Summary

Mandatory: 1 element
Must-Support: 4 elements

Structures

This structure refers to these other structures:

• AU Core Patient (http://hl7.org.au/fhir/core/StructureDefinition/au-core-patient)
• AU Core Encounter (http://hl7.org.au/fhir/core/StructureDefinition/au-core-encounter)
• AU Base Related Person (http://hl7.org.au/fhir/StructureDefinition/au-relatedperson)
• AU Core PractitionerRole (http://hl7.org.au/fhir/core/StructureDefinition/au-core-practitionerrole)

Below is an overview of the mandatory and optional search parameters. FHIR search operations and the syntax used to describe the interactions is described here.

Mandatory Search Parameters

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

1. SHALL support searching for all allergies for a patient using the patient:identifier search parameter:

   GET [base]/AllergyIntolerance?patient:identifier={system|}[code]

   Example:

    GET [base]/AllergyIntolerance?patient:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437
   

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

2. SHALL support searching using the combination patient:identifier and category search parameter:

   GET [base]/AllergyIntolerance?patient:identifier={system|}[code]&category[code]

   Example:

    GET [base]/AllergyIntolerance?patient:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437&category=medication
   

   Implementation Notes: Fetches a bundle of all AllergyIntolerance resources with the category of "medication" for the specified patient (how to search by :identifier)

3. SHALL support searching using the combination patient:identifier and code search parameter:

   GET [base]/AllergyIntolerance?patient:identifier={system|}[code]&code={system|}[code]

   Example:

    GET [base]/AllergyIntolerance?patient:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437&code=http://snomed.info/sct|293619005
   

   Implementation Notes: Fetches a bundle of all AllergyIntolerance resources with the code of an 293619005 (Ibuprofen allergy) for the specified patient (how to search by :identifier and how to search by token)

4. SHALL support searching using the combination patient:identifier and clinical-status search parameter:

   GET [base]/AllergyIntolerance?patient:identifier={system|}[code]&clinical-status={system|}[code]

   Example:

    GET [base]/AllergyIntolerance?patient:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437&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 code. This will not return any "entered in error" resources because of the conditional presence of the clinicalStatus element. (how to search by :identifier and how to search by token)
