Usage scenarios

The following are supported usage scenarios for this profile:

• Query for a patient’s problems, diagnoses, and health concerns
• Record or update a patient’s problem, diagnosis, or health concern

Comparison with other national and international specifications

A resource conforming to this profile is conformant to:

• IPA-Condition
• and MAY be conformant to
  • IPA-problem-list-item if one Condition.category problem-list-item is supplied
  • Condition (IPS) if patient is supported as Condition.subject.reference
  • US Core Condition Problems and Health Concerns if one Condition.category is supplied with a value from the US Core Problem or Health Concern value set
  • US Core Condition Encounter Diagnosis if one Condition.category encounter-diagnosis is supplied

Conformance in reverse is not guaranteed, i.e. a resource conforming to International Patient Access, International Patient Summary, or US Core MAY NOT conform to AU Core.

Profile specific implementation guidance

• Condition.category provides an efficient way of supporting system interactions, e.g. restricting searches. Implementers need to understand that data categorisation is somewhat subjective. The categorisation applied by the source may not align with a receiver’s expectations.
• The use of coding can vary significantly across systems, client applications need to understand that they may encounter codes they do not recognise and be prepared to handle those resources appropriately. Servers SHOULD populate Condition.code.text and/or Condition.code.coding.display so that client applications can at least display the condition even if the client application does not recognise the code supplied.
• An active condition is represented using “active” in Condition.clinicalStatus
• To represent that a patient does not have a condition or history of condition, an appropriate negation code is used in Condition.code
• Refutation is not expected to be handled except as above - an appropriate negation code in Condition.code and Condition.verificationStatus of “confirmed” or “unconfirmed”

Summary

Mandatory: 2 elements
Must-Support: 13 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 Core Practitioner (http://hl7.org.au/fhir/core/StructureDefinition/au-core-practitioner)
• AU Core PractitionerRole (http://hl7.org.au/fhir/core/StructureDefinition/au-core-practitionerrole)
• AU Core RelatedPerson (http://hl7.org.au/fhir/core/StructureDefinition/au-core-relatedperson)

Maturity: 0

Below is an overview of the mandatory and optional search parameters and combined search parameters. FHIR search operations and the syntax used to describe the interactions is described 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:
   • SHALL support these _revinclude parameters: Provenance:target
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

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

   Example:

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

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

2. SHALL support searching using the combination of the patient and category search parameters:
   • SHALL support these _revinclude parameters: Provenance:target
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

   GET [base]/Condition?patient={Type/}[id]&category={system|}[code]

   Example:

   1. GET [base]/Condition?patient=5678&category=http://terminology.hl7.org/CodeSystem/condition-category|encounter-diagnosis

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and category code = encounter-diagnosis (how to search by reference and how to search by token)

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

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

   Example:

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

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and a clinical status (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 category and clinical-status search parameters:
   • SHALL support these _revinclude parameters: Provenance:target
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

   GET [base]/Condition?patient={Type/}[id]&category={system|}[code]&clinical-status={system|}[code]

   Example:

   1. GET [base]/Condition?patient=5678&category=http://terminology.hl7.org/CodeSystem/observation-category|encounter-diagnosis&clinical-status=http://terminology.hl7.org/CodeSystem/condition-clinical

      active

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

2. SHOULD support searching using the combination of the patient and code search parameters:
   • SHALL support these _revinclude parameters: Provenance:target
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])
   • SHOULD support multipleOr search on code (e.g.code={system|}[code],{system|}[code],...)

   GET [base]/Condition?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}

   Example:

   1. GET [base]/Condition?patient=5678&code=http://snomed.info/sct|68566005,http://snomed.info/sct|394659003

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and condition code(s). SHOULD support search by multiple codes. The Condition code parameter searches Condition.code only. (how to search by reference and how to search by token)

   1. SHOULD support searching using the combination of the patient and onset-date search parameters:
      • SHALL support these _revinclude parameters: Provenance:target
      • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code]
      • SHALL support these onset-date comparators: gt,lt,ge,le
      • SHOULD support multipleAnd search on onset-date (e.g.onset-date=[date]&date=[date]]&...)

   GET [base]/Condition?patient={Type/}[id]&onset-date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

   Example:

   1. GET [base]/Condition?patient=5678&onset-date=ge2020-01-01T00:00:00Z
   2. GET [base]/Condition?patient.identifier=http://example.org/fhir/mrn|12345&onset-date=ge2020-01-01T00:00:00Z
