3 Action Items Review
- Chair
Status/Discussion:
  • Reviewed previous action items & decisions, including:
- DPI will involve multiple layered profiles (e.g., PnP vs. external control)
- White papers will be developed to provide a more wholistic perspective on DPI.

Decisions/Issues:

Action(s):

4 DPI Focus
- Todd
Status/Discussion:
  • There was a general discussion about the key objectives of the DPI profiles. It was reiterated that ultimately they should address work flow around device usage & integration and should directly support improved patient safety.
  • This is in reference to the traditional IHE focus on improved work flow at the enterprise integration (i.e., to the "right" of the point-of-care gateway - addressed in part by the DEC profile).

Decisions/Issues:

Action(s):

5 DPI White Paper
- Todd
Status/Discussion:

In the previous meeting, it was determined that a white paper should be developed to provide the overall perspective on DPI. This discussion addressed content that should be covered by this paper:

  • Must clearly map semantics (e.g., Rosetta) across the universe of devices covered by the DPI profiles. (Hotchkiss - this is a "show stopper"!)
  • Must provide for basic plug-and-play (PnP) connectivity
  • Should support safety interlocks (see ICE discussions)
  • Should provide a road map for potential profiles (a.k.a. "framework") and the set of use cases driving the profiles.
  • Should present a clear vision for the DPI profiles (e.g., optimizing 3 key PCD value propositions)
  • Provide an architecture that integrates the various DPI and other IHE & PCD profiles.
  • Must contain all DPI use cases. In other words, though these may also be repeated in various profiles (i.e., Volume 1 section), in that the same use case might drive multiple profiles, the general scenarios should be contained in the white paper.
NOTE: There is a close relationship between this white paper and the ISO/IEEE 11073-00000 Framework & Overview document. This should be anticipated during the planning and development phases.

Decisions/Issues:

Action(s):

6 Semantic Architecture Overview
- todd
Status/Discussion:
There was a general discusson that previewed the medical device semantic architecture discussion that was scheduled for the subsequent Vancouver standards meetings:
  • Medical Device Semantic Architecture (subject of a white paper) - this discussion reviewed the various components of medical device semantics, including formal terminology (incl. metamodel), subject-area terminology constraints (e.g., UoM vs. parameters vs. events), and semantic groups including physiologic context (a la Rosetta organization), device context (MDS, VMD, Channel, etc.), and clinical "clusters" context, which includes information from both devices and other sources - including clinicians.
Reviewed how this + DPI would relate to the 3 PCD TF volumes (Use Cases, Transactions & Semantic Content)

Decisions/Issues:

Action(s):

7 DPI Profile Content
- todd
Status/Discussion:
Key sections to the DPI white paper / profile(s) include:
  • Semantic Content Profiles - how they get leveraged
  • Service Architectures
  • Transport Technologies, including:
- QoS Guidance
- Wireless Guidance
- ...

Decisions/Issues:

Action(s):

8 DPI Issues
- Group
Status/Discussion:
Key issues to be surmounted by DPI include (in no particular order):
  • Relationship to CEN/ISO/IEEE/HL7 standards (incl. document vs. messaging vs. service orientation)
  • Are there regulatory considerations related to PnP networks?
Do potential regulatory issues affect participation in DPI profile development?
  • How to migrate from legacy device / proprietary technology solutions?
How will existing technology deployment affect manufacturers' interest in DPI.
Currently, interfaces tend to fall into
simple serial (e.g., -30200, pulse-ox, old pumps, vents, ...)
Ethernet (physio monitors)
802.11 xyz (esp. infusion pumps)
In Continua, it is BT & USB ... but this is a nascent market for the DPI profile(s),
  • Does the profile need to support multiple OPTIONAL transport elements, that can be leveraged based on the deployment requirements ... ???
Is this similar to XDS ... where there are 2-3 different "transport" mechanisms supported?
NOTE: This should be addressed in the DPI White paper or F&O...

Decisions/Issues:

Action(s):

9 Roadmap Focus
- Group
Status/Discussion:
There was a general discussion regarding the "big picture" for the DPI roadmap:
  • Start with existing transport(s)
  • Start with existing standardized application service models
  • Start with Semantic Architecture white paper
