Malcolm Clarke

Stefan Schlichting

Reinhold / Rosner
Rhoads / Karl

Issue relating to 10101R submission of XML files of all the tables (Malcolm Clarke)

  • It would be valuable for the tables in the standard to be made available in machine-readable (XML) form, but due to near term deadline (Friday, September 20, 2019) for IEEE document process and submission, and the rule that supplementary material must be available at publication time and not added later, made this impractical.
  • Therefore, a motion was proposed to "strike footnote from IEEE submission document which indicates submission of XML files of all the 10101R tables"
    • Motion made by Michael Faughn, second by Todd Cooper
    • Motion passed 11-0-0 by IEEE voting members

Devices on FHIR Discussion: Device Alerts, Events and Alarms

  • [John R. ] noted: Agenda item is to give a viewing and awareness to the HL7 FHIR Management group; further discussion would occur on DoF weekly call.... Todd 
  • Todd Cooper: Action Item for Todd Cooper to follow up w/ DaVinci folks that device alert is a different 'alert' than the to date understanding by DaVinci group Action items
  • Note: no formal document/presentation submitted to HCD WG, JSON resource definition example shown and discussed at meeting
  • Discussion to call "device" item "alertSource" from "2019-06-17AlertResourceDiscussionNotes.docx" (Action Item: John Rhoads to post to documents page of Confluence

  • John Rhoads asked if anyone had anything further to discuss on Alerting?
    • Paul Schluter noted regarding Event Phase ("start" and "End" and "Continue" captured in effective time...  Stefan Schlichting noted that when one changes the 'status of the resource'... perhaps change to "Alert Phase"

PHD IG Ballot Comment Resolution

  • Brian Reinhold noted that a discussion occurred with Clem (who has some outstanding negative items, and that Brian has responded and is waiting on Clem's review.  Clem indicated he agreed to review outstanding issues (persuasive) to be resolved (i.e., accepted by Clem).
  • Status update provided by Martin Rosner:
    • Comments and status changes to be made in GForge (and indicated updates will be added in the very near term
    • Assuming Clem's responses (are favorable), wrap up of PHD Implementation Guide (IG) items should be resolved over the next few DoF weekly calls (Wednesday, 9 am EST calls).

Abhyankar / McDonald
John Rhoads

Paul Schluter

LOINC mapping updates and Review Panel Plan

  • Dr. Abhyankar indicated that few new terms were added since the last WG meetings  into the LOINC database and due to staffing issues, she will dedicate more of her time to the database end and thus for the short term not have the resources to dedicate attention to more mappings.
  • Action Item: John Rhoads noted HCD will attempt to establish volunteer effort (perhaps through IHE) to help with the terminology review and mappings.

Terminology (Schluter)

  • Please see posted presentations here entitled "IEEE_11073_2019-09-18.Atlanta.5d.2019-09-18T10" and

Terminology report/summary (cont' from Q3)

  •  Hoping for provisional numeric codes for events and alerts by end of Oct 2109

FHIR Tooling Discussion (in preparation for Q1 Thursday joint meeting)

  • John R. will build a slide from some items in past weekend's "Connectathon"...related to alerts
  • Other topics
    • Device Alerting
    • Performance challenges at server side (e.g., can output 200 per second per device w/o or including waveforms)
    • Localization
    • Large Data issues - Experience from FHIR Connectathon like event - 
      • SDC Patient monitor - 50 - 60 devices for example (which is not realistically much from a hospital setting) - would have to write ~7K observations per second. 
      • Writing into the repository was buffered and couldn't handle them...
      • So next the observations were bundled (which optimized) - led to 160-180 observations per second...
      • Then optimized the server and memory... 
      • Next write only every 10 or so seconds (i.e., 10 second blocking)... which worked better - achieved nearly 7K observations per second...  also don't get timestamps.  Note to display on a mobile phone would likely need to do every ~2 seconds.
      • Bottleneck was really at FHIR server... throughput of the network was not the problem...
      • So from Stephan S' perspective this will really not scale up.
      • Brian R. mentioned the large amount processing that has to occur at the FHIR server side, lots of overhead as well to set up.
    • Save two-dimensional data that is where one dimension is something other than a periodic time series
      • real time sample is able to display (value versus time)
      • power spectral density or probability distribution, for example, not supported
      • suggested remedy: allowing other units like Hz (1/sec), cumulative probability
    • DoF Road map - process for the next iteration of the IG + release 5
    • ACTION: a brief but complete proposal for changes to the data type allowing for these and other useful 2-dimensional data presentations

Todd also mentioned to WG about planning for Australia WG meetings and suggested thinking about perhaps having some introductory sessions throughout the week to help the newer folks in Australia to get more engaged with the HCD group.

  • Motion made to close the IEEE portion of WG meetings
    • Motion made by John Garguilo, second by Todd Cooper 
    • Motion approved 11-0-0

Stefan Karl


Joint with FHIR @ HCD (FHIR Infrastructure Work Group Rep: Rick Geimer, room M103)

“Devices on FHIR” IG Roadmaps, R5, Resource Maturity, ...

  • Resource Maturity Level (ML): Rick noted when developing and working on IGs for trial use, FMG will be requiring attending/testing at a FHIR Connectathon Event or similar type of event.
    • Noted that IG of this group are ML STU
    • The requirement above (attending FHIR Connectathon/Test Event) applies to ML 0 or 1
  • O&O status for device
    • Device status is conflated depending on if device is implanted (vs. if for example if a device is implanted with a dead battery)
    • Looking at status of device and status of record of device...
  • Any resources planned on bringing normative (Level 4 or 5).  
    • HCD would likely bring forward DeviceMetric forward
    • Presently at maturity level 1, next is to fill out spreadsheet, do a testing event at FHIR Connectathon (or similar event if not at HL7 WG meetings)
  • Timing of R5 will likely be May 2021, and still targeting end of year 2021 (this may require an out of cycle ballot
  • ACTION ITEM : Device Metric needs to have maturity level spreadsheet completed (John Rhoads)

DoF:  Alerting Strategies (incl. DeviceAlert)

  • Todd Cooper provided a back drop for Alert
  • Rick noted that other folks are doing work on Alert resource (more FHIR Server)
    • Rick mentioned his mention is tied to subscription approach (e.g., DiVinici)
    • Todd noted alerting from/to devices are different and HCD intends to make this very clear (and in a way that is consistent and synergistic) 
    • Rick noted previously Subscription resource now split into 'Subscription' + 'Topic'
      • This was done so those using subscription would publish topic
  • DeviceAlert resource definition Review (John )
    • John showed spreadsheet providing Path, Type, Binding, Multiplicity, Definition, Comment, etc... providing informational and current state representation of alert.
    • Noted that IEEE has many alerts - embedded in the nomenclature
    • IEEE is a recognized, have an OID, and a FHIR page - tooling can expand 
    • John Garguilo mentioned to Rick about the RTMMS and nomenclature source
    • Todd mentioned the IG has two parts in which getting the solid "stuff" concrete and further cook
    • Topic is a new resource spun off from Subscription resource providing the topics allowed to subscribe to... (various channels to establish) EHR will predefine topic in which one can choose topic to "listen for"...
    • Rick mentioned and encourage folks in HCD to create a Device Alert Topic and test out in next FHIR Connectathon track...

DoF:  Server Performance re. Scaling for Patient Monitored data (e.g., SDC)

  • (Stefan Schlichting) provided background for Rick
    • High volume of data from many devices...
    • When testing with FHIR Server, the date was written but buffer was overloaded... 
  • Rick mentioned maybe trying bulk data, but no easy answer at this point...
    • May need some other folks from FHIR team who are on server side to hear about...
    • Todd asked if this could be a good topic at DevDays - and that we should give notification in the IGs
    • Rick mentioned some discussion in FIREi how to "page" the reading... also mentioned "Patch" feature
    • Rick suggested running this issue by and contacting James Agnew lead developer on HAPI 
  • ACTION ITEM: Rick suggested doing a write up and creating a GForge tracker item so the item would get a time to talk about it with FHIR team...  assign it FIREi team.  Stefan Schlichting Stefan Schlichting agreed to do the write-up against the HTTP.html page (description of FHIR use of REST)

FHIR "Localization" (issue brought forth by Paul Schluter)

  • Todd Cooper introduced topic for Rick
  • Localization: a display provides the overall 
    • How does one do the Localization in FHIR
    • There is a "text field" which could be used, but if you need to note a localization such as what language is used (e.g., Japanese, German, etc)... Rick was thinking this may have to be a unique resource for each language...
    • This might fall into an extension...
    • As a general construct, localization would include things like language, geographical info - but doesn't appear to be a place to do this...
  • Rick mentioned this seems like a common issue, but not aware of answer - so he will look into it and get back to HCD (will bring it up in Q2 today)

FHIR support for non-time-based sample arrays

  • Bjorn Andersen provided background...
  • Rick suggested getting a tracker issue in before R5 - to relax cardinality and propose the additional fields needed such as "basic science"

Done. Ticket can be found at #25034

Device Static vs. Dynamic Data in FHIR

  • This does appear to be a good use case for PATCH - perhaps HCD could participate in a Connectathon ; HAPI and ZONK both support PATCH but might not support the item 
  • ACTION ITEM: To do in parallel with Performance item above. (Stefan Karl)

HCD / FHIR Planning

  • End of Oct moving to JIRA (system will be down on a Friday and come back up on a Sunday) Lloyd will notifiy when NOT to file a new tracker...
