## Resource Profile: AU Core Condition

Official URL: http://hl7.org.au/fhir/core/StructureDefinition/au-core-condition | Version: 2.0.0-ballot
Standards status: Trial-use | Maturity Level: 2 | Computable Name: AUCoreCondition

This profile sets minimum expectations for a Condition resource to record, search, and fetch problems, diagnoses, and health concerns associated with a patient. It is based on the AU Base Condition profile and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Condition resource when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.

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 problems, diagnoses, and health concerns
- Record or update a patient's problem, diagnosis, or health concern

### 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, requesters need to understand that they may encounter codes they do not recognise and be prepared to handle those resources appropriately. Responders SHOULD populate `Condition.code.text` and/or `Condition.code.coding.display` so that requesters can display the condition even if the requester does not recognise the code supplied.
- See the Representing Body Site, Which May Include Laterality section for guidance on representing a relevant body site and associated laterality.
- 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`:
  - For indicating no known conditions or problems of any type `Condition.code` SHOULD use the code SNOMED CT 160245001 |No current problems or disability (situation)|
- Refutation is not expected to be handled except as above - an appropriate negation code in `Condition.code` and `Condition.verificationStatus` of "confirmed" or "unconfirmed"

The additional obligation for `Condition.onsetDateTime` for AU Core Responder is SHOULD:populate. There is no additional obligation for AU Core Requester, the obligation of SHALL:no-error applies.

This obligation is present in the underlying structure but due to a tooling limitation is not currently rendered in the profile view. See Zulip discussion for more information.

Usages:

- Refer to this Profile: AU Core Encounter, AU Core MedicationRequest, AU Core MedicationStatement and AU Core Procedure
- Examples for this Profile: Condition/ckd, Condition/condition-masked, Condition/noknown and Condition/uti
- CapabilityStatements using this Profile: AU Core Requester CapabilityStatement and AU Core Responder CapabilityStatement

### Notes:

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.

Parameter(s) | Conformance | Type(s) | Requirements (when used alone or in combination)
--- | --- | --- | ---
patient | SHALL | `reference` | The requester SHALL provide at least an id value and MAY provide both the Type and id values. The responder SHALL support both. The requester SHOULD support chained search patient.identifier using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile. The responder SHOULD support chained search patient.identifier using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile.
patient+category | SHALL | `reference`+`token` |
patient+clinical-status | SHALL | `reference`+`token` |
patient+category+clinical-status | SHOULD | `reference`+`token`+`token` |
patient+code | SHOULD | `reference`+`token` |
patient+onset-date | SHOULD | `reference`+`date` |
category | MAY | `token` | The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both.
clinical-status | MAY | `token` | The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both.
code | MAY | `token` | The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both. The requester SHOULD support `multipleOr`. The responder SHOULD support `multipleOr`.
onset-date | MAY | `date` | A requester SHALL provide a value precise to the second + time offset. A responder SHALL support a value precise to the second + time offset. The requester SHALL support these search comparators `gt`, `lt`, `ge`, `le`. The responder SHALL support these search comparators `gt`, `lt`, `ge`, `le`. The requester SHOULD support `multipleAnd`, and if `multipleAnd` is supported, SHALL support the search comparators `gt`, `lt`, `ge`, `le`. The responder SHOULD support `multipleAnd`, and if `multipleAnd` is supported, SHALL support the search comparators `gt`, `lt`, `ge`, `le`.

#### 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]/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:
   - 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:
   - 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:
   - 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:
   - 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)

3. SHOULD support searching using the combination of the `patient` and `onset-date` search parameters:
   - 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]]&...`), and if multipleAnd is supported, SHALL support the search comparators `gt,lt,ge,le`

   `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

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