1. Proposed Workitem: Reporting & Processing Workflow Update

  • Proposal Editor: Kevin O'Donnell
  • Editor: Kevin O'Donnell?
  • Domain: Radiology (& Cardiology?)

2. The Problem

Radiology workflows are getting more distributed; data collection, processing & reporting are more commonly spread across multiple locations, even multiple organizations.

Radiology workflows are getting more complex; more steps such as clinical processing, 3D reconstruction, and more combinations and permutations.

Radiology workflow logic is getting more sophisticated; there are examples of push, pull, centralized, distributed, data-driven, event-driven, etc.

This makes it harder for people to know who is supposed to do what next or find out what has been done. Worklists and performed procedure steps would help, but GP Worklist has proven to be difficult to implement and does not address some of the logic patterns.

Costs from manual workflow likely include slower turnaround (a key metric for radiology), extra manpower for the manual tasks, lost/dropped actions, poor resource balancing, missing data, poor coordination, poor collection of performance metrics, poor tracability, etc.

Proprietary workflows sometimes address some of the above, but at a cost in flexibility and limiting choice/ability to use preferred systems.

3. Key Use Case

<Describe a short use case scenario from the user perspective. The use case should demonstrate the integration/workflow problem.>

<Feel free to add a second use case scenario demonstrating how it “should” work. Try to indicate the people/systems, the tasks they are doing, the information they need, and hopefully where the information should come from.>

4. Standards & Systems

DICOM Unified Procedure Step (Sup 96)

5. Discussion

This is basically about updating the existing Reporting and PostProcessing Profiles (which seem to have had very limited traction), to be easier to implement and use, in part through using UPS.

If we agree that the need/business case does exist for these profiles, this would be about taking a second crack at it.

UPS Status

  • Radiotherapy implemented Sup 74 based on Sup 96 and successfully tested at two Connectathons
  • currently in the process of moving from Frozen Draft to Final Text
  • due to changes/improvements during review will be re-balloted in October

UPS Benefits

  • retains many of the attributes used in GP-WL for easier transition
  • much simpler object management logic
  • supports push workflow, pull workflow, self-scheduling, etc.
  • provides a subscription model for monitoring procedure steps
  • improves referencing of input/output data, handling local network, media or XDS retrieval


  • SIIM is working on mapping/modeling radiology workflow steps and patterns (first draft completed)
  • good potential for collaboration

<Include additional discussion or consider a few details which might be useful for the detailed proposal>

<Why IHE would be a good venue to solve the problem and what you think IHE should do to solve it.>
<What might the IHE technical approach be? Existing Actors? New Transactions? Additional Profiles?>
<What are some of the risks or open issues to be addressed?>

<This is the brief proposal. Try to keep it to 1 or at most 2 pages>
