Status/Discussion:

3. Profile and Work Item Update

  • TF: John Rhoads is making editorial changes to Vol. 2. He provided a Wiki page to track changes to the FT. John Garguilo asked which version applies to the Connectathon. John Rhoads responded that the changes can be used as necessary to resolve problems, but otherwise it is not the version tested.
  • MEM Security: Will go to PC for ballot to release for public comment.

4. New Work Items

  • John Rhoads referred to the IHE Profile Proposal Process. The TC now performs a technical evaluation. One of the profiles under consideration has a Detailed Profile Proposal. He asked whether the other two need these or if the Brief Profile Proposals are sufficiently complete. When these have been assessed, the PC will determine which are pursued.
Asynchronous Data Query: John Rhoads led discussion and noted the overlap and relationship to SPD and that existing actors or profiles may be affected. Paul suggested there be reference to SPD in the document. John Garguilo agreed that existing profiles and actors may not be clear at this time, but may be affected. There was a consensus that the document, with possible modification by Ken (author) is ready for the PC’s consideration. A ballot is not required.
Really Consistent Time (WP): John Rhoads summarized the proposal and the reasons it is needed. Paul indicated that he suggests the paper provide detail on how consistent time can be employed/administered and provide higher precision on the network. John summarized that this includes guidelines for testing standards, achieving consistency. Paul added that the goal is that accurate time be provided for an event. John added that another device may provide accurate time. Requirements to be met are that the time of reporting of events will be rigorously provided and the errors known and documented. Christof asked if this is related to a testing standard or an NTP standard. Paul responded that it would be both – guidance to vendors and to network administrators. For legal purposes 5 ms is required, but it is desirable to be much shorter and would permit alignment of data from multiple devices and manufacturers. As an example, it may include a requirement for no more than one router to avoid unacceptable misalignment in a situation such as ECG from telemetry and wired data for another waveform parameter. Christof asked how this fits IHE model which is built upon standards. The response is NTP fills that role. John Garguilo asked how this relates to plug and play when the device may or may not have a clock and the accuracy of that clock may be insufficient. This even extends to FDA’s interest in where does a device start/stop. John Rhoads suggested that there is enough information and sufficiently bounded to recommend this proposal to the PC for consideration. Paul recommended that once launched others will be needed to flesh this out, including discussion with DICOM and perhaps others.
The remaining profile proposals were deferred.

6. Tooling Update: RTM:

  • Paul led discussion of adding LOINC codes to RTM for hearing tests. He communicated this to Khalil and Nitin with a request for entries into a short Excel sheet and then will schedule a meeting to take it to the next step. He will add LOINC observation identifiers as an additional column. This will permit comparison with MDC codes when they are also available. Enumerations such as body sites will be included within the OBX. John Rhoads asked if the process for submitting new terms require submitters provide a proposal in the Excel format to Paul. John Garguilo added that additions to the table be vetted to avoid vendors adding directly to the table.

Other items deferred.
