13:00-15:00: New Participants Welcoming discussion

• Committee held a broad discussion of strategic issues including

• Connectathon Testing

• Current testing process has inherent limitations that are being stressed by growing number of profiles for testing and limited number of actors in key roles (eg, Order Filler/RIS). Finding sufficient partners to fulfill "three partners rule" is increasingly difficult for some profiles.
• One possible strategy to target marketing of Connectathon participation to "hub" actors. We may need to provide incentives such as special recognition.
• SWF.b is among the profiles whose testing has so far been limited. There is recognition in the industry of the need for the profile and interest in implementing it. However, there are currently very limited testing tools to make testing attractive.

• Need for new tooling and testing processes.

• Recruit companies who have internal development tooling and encourage them to participate in an open source tool development and maintenance project.

• Review current content base and consider consolidating by actor/product groupings.

ISO Clinical Imaging Reference Standard Portfolio (RSP)

• Kevin O'Donnell is preparing this document for potential publication by ISO. It provides a catalogue of the standards used in medical imaging, their respective areas of use, and their current maturity and implementation status.

• The document is currently complete in its general outline, but requires review, confirmation of some of the evaluations of standards and input on the implementation status of other standards.
• Committee agreed to review the document and provide input as follows:

• Chris Carr: General review of structure and coherence
• Wim: General introduction and review for what can be removed

15:00-16:00: Closing evaluation

IDEP

• • Did we line-by-line the entire document
    • 1475 of 1515 lines reviewed (75 of 85 pages)
  • How ready is it to go out for TI
    • Soonish to almost
  • How did the work fit in the allocated bandwidth?
    • A few review items left undone this week but no development undone
  • Review the evaluation. Which complexity/uncertainty/effort points missed the mark?
    • Evaluation expected more transactions could be reused. In the end, three new transactions were created instead of one and a further transaction (RAD-128) requires a CP
    • These transactions did not represent new functionality
    • Missed some uncertainty points around technical appropriateness of current transactions
    • Some approaches were changed based on committee feedback
  • What significant debates in TI-prep were not anticipated in the Kickoff or PC-Prep
    • Amount of detail to put in actor section
  • What residual risks are worth noting
    • Testing will be complex, which may hinder formal adoption
  • Does it feel we've met all the use cases
    • Yes
  • Did the promised resources manifest
    • No input from HCA, some from InfoWay
  • What vendors are engaged (for each actor):
    • Vital Images (Canon), GE (XDS / XCA), Change, Visage, HDIRS, RSNA Image Share, Canada Health Infoway
  • Who should specifically be targeted for TI notification (implementors & advocates)
    • Canada Health Infoway, RSNA Image Share, ACR ("Ditch the disk")
  • When will we have sample data/objects
    • N/A
  • Do you need any tcons between now and TI Publication
    • Yes: <= 2 x 2 hours needed
  • Did public comments result in a design change?
    • PC proposed several new transactions. These were sketched out before TI meeting but it wasn't feasible to complete them entirely without direction
  • Was the profile where it needed to be at the end of the TI meeting, if not what was the gap
    • One section needs updating based on pending decision by committee
    • One and a half sections need review but no major revisions expected

16:00-17:00: Technical Framework Maintenance (7)

EBIW

• • Did we line-by-line the entire document

Yes

• • How ready is it to go out for TI: Completely, Almost, Soonish, Hmmm

Almost, just minor mechanical (FHIR Query is a separated task)

• • How did the work fit in the allocated bandwidth? (Time to spare? Just right? Things were left undone?)

(Check the numbers - without FHIR mostly right, maybe a bit over. With FHIR, definitely over)

• • Review the evaluation. Which complexity/uncertainty/effort points missed the mark?

FHIR Complexity was higher than estimated, uncertainty was "right" (because we didn't make a real decision) Committee made the choice to expand the scope to two mechanisms so that effort is over and above.

• • Or alternatively, estimate how many points you went over and assign the overage effort/complexity/uncertainty to the appropriate points.
  • What significant debates in TI-prep were not anticipated in the Kickoff or PC-Prep

None

• • What residual risks are worth noting

Resolving FHIR/UPS-RS

• • Does it feel we've met all the use cases

Yes

• • Did the promised resources manifest

Got some of the interested people which was adequate, more would have been nice but not really a problem.

• • What vendors are engaged (for each actor)

Copy from PC

• • Who should specifically be targeted for TI notification (implementors & advocates)

HIMSS-SIIM Enterprise Group, SIIM Podcast, EBIW Mtg at SIIM, Need to reach out to PoCUS modalities/EMRs/Cameras, maybe AHA, AHRA? ACEP (emerg phys)

• • Did this domain/committee have the right scope/expertise for the profile

Mostly yes

• • How/When will testing happen (e.g. sample data/objects, which connectathon)

Cleveland (with recruiting for cameras and EMRs),

• • Do you need any tcons between now and TI Publication

One just in case for basic TI, definitely a few for FHIRQuery prep for PC

• • Was the profile where it needed to be at the start of the TI meeting, if not what was the gap

Except for the FHIR Extension, yes.

• • Was the profile where it needed to be at the end of the TI meeting, if not what was the gap

Except for the FHIR Extension, yes.

• • What is needed for the profile to deliver on the benefit statement in the approved proposal

Closing evaluation: Profile_Development_Process_for_First_Timers#Annex:_Kickoff_Closing_Assessment

Total Hours for week:

• Import and Display of External Priors ()
• Encounter-based Imaging Workflow for Lightweight Devices ()
• Technical Framework Maintenance ()

DICOM Update of SNOMED Codes

• DICOM is updating from old RT codes to current CT codes
• Both old and new codes will need to be accommodated for the foreseeable future
• Wim will Open CP (#426: SNOMED Code Migration). Committee to do group effort to identify scope of profiles and codes affected.
• Need to add notes in TF to describe the implications of migration to new codes
• Current test objects all use old codes. Tests and samples will have to migrate over time to incorporate new codes. Possible to test mixed old/new code sets to test the impact of implementation.

Scope for Maintenance

• CP tracking Spreadsheet: https://docs.google.com/spreadsheets/d/1TmSwnn4AIiXqFLc_AtzP0dNd9LUWnA-ZcCjBMKpLzp4/edit#gid=0
• Review incoming CPs ftp://ftp.ihe.net/Radiology/TF_Maintenance/0.Submitted_CPs/
• Identify CPs that should be focused on this cycle and assign owners
• Review ballot comments
• Review CPs that have been worked on
• Review how to maintain the public comment solution wiki page (http://wiki.ihe.net/index.php/Radiology_-_Public_Comment_Resolutions)
