StructureDefinition: ADHA Core Encounter [Active]

The purpose of this profile is to provide a core representation of an encounter 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 Encounter that are supported.

This profile is designed to set a core Encounter standard for:

  • Query for a patient’s encounters
  • Query for records associated with a specific patient encounter
  • Record or update an encounter and records associated with an encounter

Profile specific guidance

  • Encounter.type supports categorisation and 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.
  • In an exchange with the My Health Record system Encounter.status is “finished”.
  • The Encounter resource can represent a reason using either a code with Encounter.reasonCode, or a reference with Encounter.reasonReference to a Condition or other resource.
    • Although both are marked as must support, sending systems are not required to support both a code and a reference, but they SHALL support at least one of these elements.
    • A receiving or persisting system SHALL support both elements.

Boundaries and relationships

This profile is referenced by ADHA Core Condition, ADHA Core DocumentReference, ADHA Australian Immunisation Register Notice, ADHA Core Flag, ADHA Record of Immunisation from Australian Immunisation Register, ADHA Core Immunization, ADHA Core MedicationRequest, ADHA Core Observation, and ADHA Core Procedure.
