4 Vancouver Meetings Review
- Todd
Status/Discussion:

There was a general review of the standards meetings held in Vancouver 2008.09.14 - 19 (IEEE 11073 / ISO TC215 WG7 / HL7 DEV WG):

  • JIC ("WG9") Update: Sunday was a meeting of the CEN/HL7/ISO Joint Initiative Council ("JIC") that is convened (for administrative purposes only) as ISO TC215 WG9. A new "subcommittee" is being formed to address semantic harmonization / development coordination between the various groups. This will provide an additional opportunity for the 11073 semantics to be recognized within the health informatics standards community.
  • UCUM: Gunther Schadow agreed to submit UCUM to ISO TC215 for standardization. At this point, it is a specification that he maintains at the Regenstrief Institute.
  • "ICE" Review: A joint tcon was held between the Vancouver meeting participants and the ASTM F29 "ICE" (Integrated Clinical Environment) project team, which was meeting simultaneously in Cambridge MA @ CIMIT.
- An updated draft of the top-level ICE standard was reviewed - this was the first time many members of the Vancouver group had had a chance to see this version of the document.
- The group had an extended discussion of the ICE conceptual model, with some of the following observations:
  • Box #2 - Could be a combination of a:
Device Semantic Specialization Profile (not DPI specific)
and
DPI PnP profile
  • Box #5 - Would map to a PnP Device manager
Question:Can multiple DeviceManager actors be supported in a single ICE network?
  • Box #7=>#9 -
Question:Is presentation to (9) within the ICE scope? [Note: Hotchkiss response - "Absolutely!"]
  • Box #11 - This could be an IHE DEC Gateway
- There was also a discussion regarding the various topologies to which the ICE conceptual model could be applied, such as surgery, ICU, sub-acute ... home ...
- General opinion coming out of the Vancouver meetings was that the ICE document needed to provide a broader range of use cases, that it should address the requirements that arise from various topological deployments (or at least a framework for how those requirements may be organized and addressed), and a stronger foundation for the "-ilities" that are transitive across the conceptual model components and potential ICE deployment environments.

Decisions/Issues:

  • As appropriate & agreed upon, the DPI White Paper should include / reference use cases identified in the ICE document. It is the intent that PCD DPI profiles will directly support ICE compliant networks.

Action(s):

5 Transport Technologies
- Group
Status/Discussion:

The DPI WG had a general discussion regarding the transport technologies & topologies that should be considered for DPI. These were also considered with respect to the ICE conceptual model.

  • ISO/IEEE 11073-30200: Cable connected (RS-232 & Ethernet) could be used for the ICE #4/#5 links.
  • ISO/IEEE 11073-30400 (Ethernet): Would support the #5/#7 link
  • Wireless & Infusion Pumps: Most infusion pumps today are focused on wireless connectivity, and wired links are typically only supported when absolutely necessary (at least that's the direction the industry is heading in). As a result, any DPI transport discussion must include PnP wireless connectivity.
- #8 might be a centralized infusion management system
- #4 could be a Wi-Fi connection
- Pump must be able to communicate at all times with a centralized #8 Mother Ship
- #7 is an infusion management system
- #11 could be an ADT / Pharmacy etc. interface
additionally
- #8 could be a physio monitor
- #2 would be an infusion pump
  • Based on this, an infusion pump would need to have two physical interfaces OR it would have a single radio that would:
- Establish a PoC PnP connection (e.g., to a physio monitor or local device manager)
- Support access to a remote eMAR
NOTE: A physio monitor (for example) could also provide a portal to the remote infusion management system. It would be good to draft up some use cases for this:
- Local "safety interlocks" + medication changes that require remote system validation
- PCA (see use case in ICE 3/25 document)
  • Portal "window" to remote application (wired / wireless)

<Jan will provide wording for this use case>

  • Key Wireless Issues:
- Local (10 - 15') or Wi-Fi or cloud?
- Device-patient correlation / pairing (state model)
- Segmenting data fgrom other wireless network users & applications
  • DPI, including wireless transports, must be viewed from a logical layering perspective.

Decisions/Issues:

  • DPI WP shall provide a layered perspective on the various required components.
