How do I create Modality Worklist for a patient in DCM4CHE using HL7 message?

I have managed to create Patients in DCM4CHEE using HL7 messages. I have also created Studies, Series and Observation Reports for respective Patients using only HL7 messages. But I am stuck at Modality Worklist. I cannot find sample HL7 messages to create MWLs. Help will be greatly appreciated.

Figured it out.

I basically used this ER7 sample message to create a patient along with a Modality Worklist in my DCM4CHEE:

MSH|^~\&|HMIS|DUHS|PACS||20181016115248||OMI^O23^OMI_O23|20181016115248|P|2.5.1||||||UNICODE UTF-8

The key was to use OMI^O23^OMI_O23 as the trigger event and providing Modality at OBR-24, and (for some reason) not leaving OBR-19 and OBR-20 empty.

I am not sure about your exact workflow and I do not know DCM4CHEE. I am answering in terms of HL7 only.

ORM (Order Entry) message is generally good candidate to process Orders. The Order is then converted to Modality Worklist Item. I do not know if this works with DCM4CHEE though.

Following is general template of ORM message O01 event:

MSH|^~\&|HIS_APP|HIS_FACILITY|PACS_APP|PACS_FACILITY|20130614131415||ORM^O01|MsgCtrlId_ORM|P|2.3
PID|1||PatientID||Patient Name||20000514|F||||||||||AdmID
PV1|1|OP||||||^Ref Phy||||||||||||50
ORC|NW|||||||||||^Req Phy|||||^Institution Name
OBR|1|ACC.NO.01||SPSID^SPSDesc|ROUTINE||||||||||RPDesc|||SSName|RPID|SPSLocation|SSAETitle|||CT|||||||Reason For Proc|||SchPerPhyName||20130614132030
ZDS|StudyIUID

This is from 2.3 version; you are using 2.5.1. All 2.x versions are backward compatible; so I hope that should not be an issue.

Note the ZDS segment which also accepts Study Instance UID.
