## Artefacts Summary

Page standards status: Informative

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

### Requirements: Actor Definitions

The following artifacts define the types of individuals and/or systems that will interact as part of the use cases covered by this implementation guide.

AU eRequesting Filler | The AU eRequesting Filler is a system that is responsible for finding and retrieving diagnostic request fulfilments so that service providers can fulfil them.
AU eRequesting Patient | A system that allows patients or their representatives to view diagnostic requests and fulfilment of diagnostic requests.
AU eRequesting Placer | The AU eRequesting Placer is a system that is responsible for creating diagnostic requests.
AU eRequesting Server | The eRequesting Server is a system that accepts diagnostic service requests and makes diagnostic service requests accessible.

### Behavior: Capability Statements

The following artifacts define the specific capabilities that different types of systems are expected to have in order to comply with this implementation guide. Systems conforming to this implementation guide are expected to declare conformance to one or more of the following capability statements.

AU eRequesting Filler CapabilityStatement | This CapabilityStatement describes the basic rules for the AU eRequesting Filler actor that is responsible for finding and retrieving diagnostic request fulfilments so that service providers can fulfil them. The complete list of FHIR profiles, RESTful operations, and search parameters supported by AU eRequesting fillers are defined in this CapabilityStatement.
AU eRequesting Patient CapabilityStatement | This CapabilityStatement describes the basic rules for the AU eRequesting Patient actor that is the digital interface that allows patients or their representatives to view diagnostic requests and fulfilment of diagnostic requests. The complete list of FHIR profiles, RESTful operations, and search parameters supported by AU eRequesting patient clients are defined in this CapabilityStatement.
AU eRequesting Placer CapabilityStatement | This CapabilityStatement describes the basic rules for the AU eRequesting Placer actor that is responsible for creating diagnostic requests. The complete list of FHIR profiles, RESTful operations, and search parameters supported by AU eRequesting placers are defined in this CapabilityStatement.
AU eRequesting Server CapabilityStatement | This CapabilityStatement describes the basic rules for the AU eRequesting Server actor that is is a system that accepts diagnostic service requests and makes diagnostic service requests accessible. The complete list of FHIR profiles, RESTful operations, and search parameters supported by AU eRequesting servers are defined in this CapabilityStatement.

### Structures: Abstract Profiles

These are profiles on resources or data types that describe patterns used by other profiles, but cannot be instantiated directly. I.e. instances can conform to profiles based on these abstract profiles, but do not declare conformance to the abstract profiles themselves.

AU eRequesting Diagnostic Request | This profile sets minimum expectations for a ServiceRequest resource that is used to record, search, and fetch information about diagnostic requests for a patient. It is based on the AU Base Diagnostic Request and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the ServiceRequest when conforming to this profile.
AU eRequesting Task | This profile sets minimum expectations for a Task resource that is used to record, search, and fetch information about a task to be performed. It is based on the Task and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the Task when conforming to this profile.

### Structures: Resource Profiles

These define constraints on FHIR resources for systems conforming to this implementation guide.

AU eRequesting Communication Request CopyTo | This profile sets minimum expectations for a CommunicationRequest resource that is used to define a copy-to clinician or copy-to patient as a report recipient. This is differentiated from an urgent practitioner communication as priority may not be urgent and the requester will not be the recipient. It is based on the CommunicationRequest and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the CommunicationRequest when conforming to this profile.
AU eRequesting Coverage | This profile sets minimum expectations for a Coverage resource that is used to record, search, and fetch information about insurance or medical plan or a payment agreement for a patient. It is based on the AU Base Coverage and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the Coverage when conforming to this profile.
AU eRequesting Imaging Request | This profile sets minimum expectations for a ServiceRequest resource that is used to record, search, and fetch information about diagnostic imaging requests for a patient. It is based on the AU eRequesting Diagnostic Request and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the ServiceRequest when conforming to this profile.
AU eRequesting MHR Consent Withdrawal | This profile sets minimum expectations for a Consent resource to record, search, and fetch a My Health Record (MHR) consent withdrawal. It is based on the Consent and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Consent when conforming to this profile.
AU eRequesting Pathology Request | This profile sets minimum expectations for a ServiceRequest resource that is used to record, search, and fetch information about pathology requests for a patient. It is based on the AU eRequesting Diagnostic Request and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the ServiceRequest when conforming to this profile.
AU eRequesting Task Diagnostic Request | This profile sets minimum expectations for a Task resource that is used to record, search, and fetch information about a diagnostic request task to be fulfilled. It is based on the AU eRequesting Task and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present when conforming to this profile.
AU eRequesting Task Group | This profile sets minimum expectations for a Task resource that is used to record, search, and fetch information about a group of tasks that are part of the same fulfilment group. It is based on the AU eRequesting Task and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present when conforming to this profile.

### Structures: Extension Definitions

These define constraints on FHIR data types for systems conforming to this implementation guide.

AU eRequesting Display Sequence | This extension applies to the AU eRequesting Diagnostic Request profile and any derived ServiceRequest profiles. The display sequence is an integer assigned to an individual test or service in a ServiceRequest that matches the sequence as seen on a paper request form. The ability to sort on sequenceNumber more easily allows for reconciliation of paper and digital requesting data by the filler, especially for collection centre staff within a pathology collection centre.
AU eRequesting Fasting Precondition | This extension applies to the AU eRequesting Diagnostic Request profile and any derived ServiceRequest profiles. The fasting precondition is a code that indicates the recommendation related to the fasting status of the patient as a precondition to the diagnostic procedure or test being requested.

### Terminology: Value Sets

These define sets of codes used by systems conforming to this implementation guide.

AU eRequesting Coverage Type and Self-Pay Codes | Coverage type and self-pay codes typically used in the Australian eRequesting context.
AU eRequesting Fulfilment Task Tags | Task tag values for labelling and differentiating fulfilment of tasks used in an Australian eRequesting context.
AU eRequesting RequestStatus | ServiceRequest status values used in the Australian eRequesting context.
AU eRequesting Task Status | Task status values used in the Australian eRequesting context.
RANZCR Radiology Referral | Standard codes for use in requesting radiology tests in Australia, derived from the RANZCR Radiology Referral Set (RRS).

### Terminology: Code Systems

These define new code systems used by systems conforming to this implementation guide.

AU eRequesting Communication Request Reason | Reason codes for a communication request used in the Australian eRequesting context.
AU eRequesting Task Tag | The AU eRequesting Task Tag code system provides concepts that represent tag values for labelling tasks in an Australian eRequesting context.
