The purpose of this profile is to provide a core representation of a generic observation for the electronic exchange of health information between individuals, healthcare providers, and the My Health Record system infrastructure in Australia.
This profile identifies the additional constraints, extensions, and value sets that build on and extend Observation that are supported.
Where a more specific Observation profile is applicable, e.g. diagnostic result or vital signs, an implementation SHALL ensure the resource conforms to that specific profile.
This profile is designed to set a core Observation standard for:
This profile may be referred to by APIs, which will be listed here when available.
Observation.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.Observation.subject and the fetus as Observation.focus.Usage:
Description of Profiles, Differentials, Snapshots and how the different presentations work.

This structure is derived from Observation
Summary
Mandatory: 4 elements
Must-Support: 19 elements
Structures
This structure refers to these other structures:
Other representations of profile: CSV, Excel, Schematron
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.
| Name | Type | Conformance | Description | Path |
|---|---|---|---|---|
| category | token | SHALL | The classification of the type of observation | Observation.category |
| subject:identifier | token | SHALL | The subject that the observation is about | Observation.subject.identifier |
| code | token | SHALL | The code of the observation type | Observation.code |
| date | date | SHALL | Obtained date/time. If the obtained element is a period, a date that falls in the period | Observation.effective |
| status | date | SHOULD | The status of the observation | Observation.status |
The following search parameters and search parameter combinations SHALL be supported:
SHALL support searching for all observations for a patient using the subject:identifier search parameter:
GET [base]/Observation?subject:identifier={system|}[code]
Example:
GET [base]/Observation?subject:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437
Implementation Notes: Fetches a bundle of all Observation resources for the specified patient (how to search by :identifier)
SHALL support searching using the combination subject:identifier and category search parameter:
GET [base]/Observation?subject:identifier={system|}[code]&category[code]
Example:
GET [base]/Observation?subject:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs
Implementation Notes: Fetches a bundle of all Observation resources with the category of "vital-signs" for the specified patient (how to search by :identifier and how to search by token)
SHALL support searching using the combination subject:identifier and code search parameter:
GET [base]/Observation?subject:identifier={system|}[code]&code={system|}[code]
Example:
GET [base]/Observation?subject:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437&code=http://snomed.info/sct|75367002
Implementation Notes: Fetches a bundle of all Observation resources with the code of an 75367002 (Blood pressure) for the specified patient (how to search by :identifier and how to search by token)
SHALL support searching using the combination of the subject:identifier and date search parameters:
GET [base]/Observation?subject:identifier={system|}[code]&date=[date]
Example:
GET [base]/Observation?subject:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608000228437&date=ge2013-03-14
Implementation Notes: Fetches a bundle of all Observation resources for the specified patient that have a date greater than or equal to 14 March 2013. (how to search by :identifier and how to search by date)
