1. Proposed Workitem: Maintenance of Radiology Profiles Published in 2017 and earlier

  • Proposal Editor: Lynn Felhofer (felhofer.lynn@gmail.com), IHE Radiology Technical Project Manager
  • Editor: current members of the RAD Technical Committee, and hopefully additional recruits
  • Date: N/A (Wiki keeps history)
  • Version: N/A (Wiki keeps history)
  • Domain: Radiology

2. The Problem

A dedicated but finite number of Radiology Technical Committee members is responsible for both creating new work items and maintaining the growing list of existing Technical Framework documents. The Radiology Domain applies some Technical Committee resources to processing Change Proposals, primarily during face-to-face meetings. Progress in reducing the backlog has slowed. The RAD Domain is publishing more new TI supplements every year than we move to Final Text, and some TI Supplements are kept from moving to Final Text due to unresolved CPs.

PUBLISHED DOCUMENTS: In Summer 2017, the Radiology Domain has:

  • 19 Final Text Profiles in the Radiology Technical Framework
  • 22 Trial Implementation (TI) Profiles
  • 3 of these are new for 2018 Connectathons (SOLE, MAP, RD) (Note: At the time of this proposal, RD is in Public Comment prior to TI publication)
  • Approximately 6 Trial Implementation Profiles are still TI because of open CPs or are pending update because they’re out-of-date (BIR, CDS-OAT, XDR-I, MRRT, MHD-I, SWF.b)
  • 6 of these have never been tested at a Connectathon (CXCAD, XRR-WD, MHD-I, PAWF, RRR-WF, SMI)
  • 5 additional Trial Implementation Supplements that modify existing profiles (extensions for DBT, IOCM, MAWF, SWF (MIMA), and NMI)
  • (white papers are not accounted for in this proposal)

CHANGE PROPOSALS: Entering the 2017-18 publication cycle, as of July 1, 2017, there are:

  • 12 Submitted CPs (awaiting assessment)
  • 75 Assigned CPs (awaiting completion, committee review, and balloting)
  • 24 CPs are currently assigned to someone who is no longer active on the Radiology Technical Committee.
  • Assigned CPs broken into rough categories look like this:
Category Num of CPs
XDS-I / XDR-I / Metadata 21
HL7v2 13
HL7 <-> DICOM 6
DICOM 6
MRRT 3
MHDI 1 (large)
REM 4
Other (TCE, IID, PGP) 5
Editorial 12
Assess for possible cancellation 5


Recent CP Ballot / Technical Framework history:

  • 2013-14: 2 CP ballots, 8 Final Text CPs, 1 Profile (IOCM) moved to Final Text Rev 13.0
  • 2014-15: 3 CP ballots, 28 Final Text CPs, 0 Profiles moved to Final Text Rev 14.0
  • 2015-16: 0 CP ballots, 1 Profile (DBT) moved to Final Text Rev 15.0
  • 2016-17: 1 CP ballot, 13 Final Text CPs, 0 Profiles moved to Final Text Rev 16.0

Some recent barriers to CP progress:

  • Some profiles have taken more Technical Committee time than anticipated (XRR-WD, RRR-WF)
  • MHD-I is being treated as a “large CP”
  • Too few active Technical Committee members with deep HL7v2 expertise
  • Active Technical Committee members have been editors of new work items (and wear lots of other standards development hats)
  • Failure to recruit enough new, active Technical Committee members
  • Others??

The audience for this proposal already knows the value of Radiology Technical Framework documentation. The Radiology domain should set aside Technical Committee resources to improve quality in existing documentation.

4. Discussion

I am proposing that the RAD Planning and Technical Committees explicitly identify maintenance as a work item to evaluate against other work item proposals for new profiles. While maintenance is always given a nod and factored in during work item selection, during the year when the Technical Committee faces a choice between spending efforts on new items vs maintenance, new items win. In recent years, we under-estimated the effort for several items, so there was scant time for CPs. Technical Committee members are asked to be one or more of: supplement editor, or a key contributor, or a reviewer to one or more work items, leaving less time for them to spend on CPs.

I am asking:

  • that the Planning Committee take the backlog of maintenance into account when making work item selections this year. When selecting work items, consider who the editors are, what existing document they maintain, and what CP work they will defer in order to work on something new. If the Planning Committee de-prioritizes maintenance, OK, but at least it will be an explicit choice.
  • that Technical Committee members be polled at the beginning of the 2017-18 cycle to identify whether they are both willing and available to contribute to CP work in Radiology. If this “RAD TF Maintenance” work item is selected by the Planning Committee, it won’t help much if RAD TC members are not available in the coming year to work on CPs. This assessment could be made as part of the ‘Detailed Work Item Proposal’ if the Planning Committee selects this as a work item.

During committee discussion of the 'detailed proposal', we can refine this deliberately-aggressive 'trial balloon' plan for addressing open RAD CPs to come up with a reasonable approach. We will need to:

  • First identify time constraints during the year that will interfere with maintenance work. I have added some, but things like DICOM meetings are missing.
  • The current plan is probably too heavily weighted in the near-term. We will need to adjust.
  • The current plan makes assumptions about which areas we should focus on first, and which are thus deferred. We will need to adjust.
  • I fully expect committee members to poke holes in this trial balloon.

6. Support & Resources

Need to determine the willingness and availability of existing RAD TC members with assigned CPs to work on them during the publication cycle.

7. Risks

New work items take priority.

Lack of HL7v2 expertise.

Availability, availability, availability.
