8.2. Outbound

HL7 messages

• General Clinical Order Message (OMG^O19) (implemented for Eye Care Transactions - Procedure Status Update [EYECARE-22])

• Imaging Order Message (OMI^O23) (implemented for AI Workflow for Imaging (AIW-I) - Procedure Update [RAD-13])

are sent to other HL7 applications/receivers if HL7 receivers are to be notified about procedure status updates or on receive of studies with(-out) any MWL items associated to it. This notification can be triggered for :

1. Updates to MWL items in archive, on :

• Receive of MPPS : Study referenced in MPPS is also associated with an existing MWL item in archive

• Receive of studies : Study is associated with an existing MWL item in archive

2. Receive of studies either by :

• DICOM Studies stored conforming to Storage AE Specification

• DICOM Studies / Bulkdata stored using STOW-RS Services

• Reports stored by HL7 ORU

If the Procedure Status Update is triggered by MPPS, and the MPPS was received with status DISCONTINUED or IN_PROGRESS, then the value set is DC or IP respectively. If the Procedure Status Update is triggered by MPPS, and the MPPS was received with status COMPLETED or if the Procedure Status Update is triggered by a Study then the value set is CM.

[2]

If the Procedure Status Update is triggered by MPPS, this value is populated from the Performed Procedure Step Start Date and Time of MPPS attributes. Alternatively, if the Procedure Status Update is triggered when a Study (which has MWL entries referencing it) is completely received, then this value is populated from the created time of the task. (The task here refers to a task created in database for sending out the HL7 notification.) Refer Synchronize external HL7 receivers on updates of Requested Procedures

[3] (1,2,3,4,5,6)

Route of Admissions (0038, 0016) DICOM attribute, if present, shall be mapped to PV1:2. If this DICOM attribute is absent, default “U” (denoting Patient Class as Unknown) shall be used.

Each Other Patient IDs Sequence (0010,1002) item is populated in patient identifiers list in the specified segment field separated using Repetition Separator ~

[5] (1,2,3)

If outgoing notification message is OMG^O19, Study Instance UID is sent in OBX segment field 5, else for OMI^O23 notification, IPC segment field 3 is used.

[6] (1,2,3,4)

Set to current date time when notification is sent out.
