### C.30.2 Unified Procedure Step Scheduled Procedure Information Module

Table C.30.2-1 specifies the Attributes that describe the Unified Procedure Step (UPS) to be performed. The UPS may or may not be scheduled for a specific time or device, or may simply represent a piece of work that is intended to be performed.

Table C.30.2-1. Unified Procedure Step Scheduled Procedure Information Module Attributes

Attribute Name | Tag | Attribute Description
--- | --- | ---
Scheduled Procedure Step Priority | (0074,1200) | Priority of the scheduled Procedure Step Enumerated Values: HIGH used to indicate an urgent or emergent work item, equivalent to a STAT request. MEDIUM used to indicate a work item that has a priority less than HIGH and higher than LOW. It can be used to further stratify work items. LOW used to indicate a routine or non-urgent work item.
Scheduled Procedure Step Modification Date and Time | (0040,4010) | Date and time when the Scheduled Procedure Information was last modified or first created (whichever is most recent). ### Note This Attribute should be automatically updated by the worklist management system whenever any modification is made to Unified Procedure Step Scheduled Procedure Information Module Attributes of a Unified Procedure Step.
Worklist Label | (0074,1202) | A label identifying the worklist to which the Procedure Step instance belongs.
Procedure Step Label | (0074,1204) | A label describing the task of the Procedure Step in text appropriate for displaying in the user selection interface.
Comments on the Scheduled Procedure Step | (0040,0400) | User-defined comments on the scheduled Procedure Step.
Scheduled Station Name Code Sequence | (0040,4025) | Identifying names within the enterprise of the equipment for which the Procedure Step is scheduled. The names conveyed in Code Value (0008,0100) may be the same as the AE Titles, but do not have to be. Zero or more Items shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
Scheduled Station Class Code Sequence | (0040,4026) | Classes of the equipment for which the Procedure Step is scheduled. Zero or more Items shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
Scheduled Station Geographic Location Code Sequence | (0040,4027) | Geographic locations of the equipment for which the Procedure Step is scheduled. Zero or more Items shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
Scheduled Human Performers Sequence | (0040,4034) | Human performers that are scheduled to be involved or responsible for performing the Procedure Step. Zero or more Items shall be included in this Sequence.
>Human Performer Code Sequence | (0040,4009) | Human performer that is involved or responsible for performing the Procedure Step. Only a single Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
>Human Performer's Name | (0040,4037) | Name of the human performer.
>Human Performer's Organization | (0040,4036) | Organization to which the human performer is accountable for the activities in the Procedure Step.
Scheduled Procedure Step Start DateTime | (0040,4005) | Date and time at which the Procedure Step is scheduled to start.
Expected Completion DateTime | (0040,4011) | Date and time at which the Procedure Step is expected to be completed.
Scheduled Procedure Step Expiration Date Time | (0040,4008) | Date and time after which the Procedure Step is meaningless or undesirable.
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” | Baseline CID is CID 9231 “Workitem Definition”. ### 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 Description” |
>Content Item Modifier Sequence | (0040,0441) | Sequence that specifies modifiers for a Scheduled Processing Parameter Content Item. One or more Items are permitted in this Sequence.
>>Include Table 10-2 “Content Item Macro Attributes Description” |
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 If the Procedure Step does not require input information, the Input Readiness State may be READY when the Input Information Sequence is empty. There is no guarantee that the referenced instances will still be available at the referenced location when retrieval is attempted. 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” |
Study Instance UID | (0020,000D) | Unique Study identification that shall be used for the created Composite SOP Instances resulting from this Unified Procedure Step.
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.
>Include Table 10-3c “Storage Macro Attributes” |
