Scheduled Workitem Code Sequence

(0040,4018)

Coded description of the Procedure Step.

Only a single Item shall be included in this Sequence.

>Include Table 8.8-1 “Code Sequence Macro Attributes”

Note

This CID has generic workitems. An implementation may choose to define more specific, detailed workitems.

Scheduled Processing Parameters Sequence

(0074,1210)

Processing parameters to be used by the performing system when carrying out the Procedure Step.

Zero or more Items shall be included in this Sequence.

>Include Table 10-2 “Content Item Macro Attributes”

>Content Item Modifier Sequence

(0040,0441)

Input Readiness State

(0040,4041)

Readiness state of the Input Information Sequence (0040,4021) and the referenced Instances.

Enumerated Values:

INCOMPLETE

The Input Information Sequence is not yet complete and additional Instance references might be added.

UNAVAILABLE

The Input Information Sequence is complete but one or more of the referenced Instances might not yet be available from the referenced source(s).

READY

The Input Information Sequence is complete and the referenced Instances are available from the referenced sources.

Note

  1. If the Procedure Step does not require input information, the Input Readiness State may be READY when the Input Information Sequence is empty.

  2. There is no guarantee that the referenced Instances will still be available at the referenced location when retrieval is attempted.

  3. There is no requirement to confirm the presence of referenced media prior to setting the Input Readiness State to READY.

Input Information Sequence

(0040,4021)

References to Information Objects needed to perform the scheduled Procedure Step.

Referencing unencapsulated HL7 documents is described further in Section C.12.1.1.6. See also Input Readiness State (0040,4041).

Zero or more Items shall be included in this Sequence.

>Include Table 10-3b “Referenced Instances and Access Macro Attributes”

Output Destination Sequence

(0040,4070)

The destination to which the performer is requested to store the output objects generated

Zero or more Items shall be included in this Sequence.

Each Item constitutes a separate storage request.

The performing system might not support the requested storage protocol or not be configured for the desired destination. The performing system may, additionally or as a fallback, be configured to store output objects to a default destination or retain them locally.

The actual location(s) to which Instances are successfully stored is recorded in the Output Information Sequence (0040,4033).

Whether to report failure of one or more of the storage requests as a failure of the work item is at the discretion of the performing system.
