Discussion

Item Topic Discussion
1 Introductions & Agenda Review
- Chair
Status/Discussion:

Decisions/Issues: Agenda approved without modification. Action(s):

2 Approval of Minutes
- Chair
Status/Discussion:

Decisions/Issues: Previous minutes were not ready for review & approval. This will be added to the agenda for the next meeting.

Action(s):

3 Fall F2F Meeting
- Chair
Status/Discussion:
  • General planning discussion regarding a face-to-face meeting in the fall.

Decisions/Issues:

  • Respironics offered to host the meeting (north part of San Diego)
  • Tentative schedule would be during the first 2 weeks of November
  • Due to travel restrictions in some companies, there was a request to provide WebEx or TCon access to the meetings.

Action(s):

  • (Todd) Issue a poll to determine interest and availability.
  • (Todd) Start a meeting wiki page for drafting of the agenda & logistics.
4 Rosetta Profile Update
- Schluter
Status/Discussion:
  • Paul provided an update for the Rosetta Terminology Mapping (RTM) profile. The RTM group has completed a lengthy review of the Public Comments submitted for this profile and are about to publish the Trial Implementation version.
  • It was noted that the current focus was on the content of the profile document, organization of the tables, and the ability to automate table validation and report generation.
  • Though some work to integrate the actual term submissions to the Rosetta tables themselves has been completed, finalizing the next revision will require considerable analysis and resolution. That will be part of the group's work over the next couple of months.
  • The Rosetta Public Comments (including new term proposals) are available on the IHE Public Comment Forum site for the RTM profile. Note that this specific link may be transient...

Decisions/Issues:

Action(s):

  • (Paul) Publish a combined set of Rosetta tables reflecting the new organization and the submitted set of proposed term mappings, though there will be many issues that will need identification and resolution in coming weeks.
  • (Todd) Send out the MDCX_ conventions to the group so that they can better interpret the proposed terms.
5 Semantic Architecture
- Group
Status/Discussion:
  • There was a general discussion about the semantic architecture or concept tree / groupings. Paul noted the acute need for this in the vent/resp area due to the large number of new terms being proposed.
  • Note: That the vent operational mode discussion is currently on hold, but will be picked back up once proposals for the general semantic architecture have been reviewed.
  • Chip (with Paul and Jan) have been engaged in an analysis of ventilator terms to identify key differentiating criteria. In this effort, they have also looked at previous work done within the 11073 group (from the late 90's) that was captured in a database tool (supporting the MDCIG prototyping effort) and a draft of the 11073-10303 ventilator device specialization draft standard. Though helpful, Chip thought that this group would probably need to come up with a different paradigm to address current and future information requirements.
  • Todd noted that the 11073-10303 draft standard was no where near completion when work stopped (due to issues outside the control of the standards group). Therefore, though it provided some useful background information, it should not be considered to represent the thinking of that group.
  • Semantics can be broken down into various types such as Observations, Events, Waveforms, etc.; however, they often share a common semantic description, and that should be maintained whenever possible.
  • Location of the measurement (patient vs. machine) and direction (insp vs. exp) was also a very important distinction to capture for differentiation of semantic descriptors.
  • Jan noted that we first needed to establish an architectural model for these semantics and then organize the term concepts accordingly.
  • Clinical review of the resulting proposed semantics is also key for validation of the approach, and should be pursued (at least within this group) as soon as a draft approach has been selected.

Decisions/Issues:

  • The IHE Implantable Device - Cardiac (IDC) group is also addressing similar issues. We should coordinate between the two activities.
  • Some simple graphic tree representations (or MindMaps) should be developed to help understand and compare various architectural approaches.

Action(s):

  • (Chip) Complete his analysis tables and publish for consideration at the upcoming 2008.08.20 meeting.
  • (Todd) Develop a number of MindMap's reflecting the current semantic architecture, vent information model, and Chip's nomenclature model for consideration at the next meeting.
