PCD Profile Device Point-of-Care Integration (DPI)

From IHE Wiki
Jump to: navigation, search


The Device Point-of-care Integration (DPI) profile proposal is concerned with use cases that involve the interoperability of equipment around the point-of-care, often patient connected. In previous PCD development Cycles, this profile was named "plug-and-play (PnP)"; however, after further consideration, this was seen as a bit too narrow and thus the DPI moniker more accurate and inclusive. The profile will focus primarily on technical interoperability (e.g., Volume 2 - Transactions) but will integrate with device specialization "semantic content" profiles to provide for interoperability from the physical connection to abstract device data and services.

It should be noted that the DPI profile is viewed as foundational (e.g., as the ITI XDS profile set), and additional profiles shall be added. For example, DPI-PNP vs. DPI-XC (external control). Therefore, some of the current discussion will look at the overall scope of DPI, and generate a roadmap of profiles, some of which are intended for the next PCD profile development cycle (e.g., basic Plug-and-Play), and some that will come in future cycles (e.g., closed-loop control).

NOTE: DPI-related wiki pages may be seen on the special DPI category page.

DPI Profile Discussions

NOTE: The following proposed links are pending approval by the IHE PCD in 2008.11. Proposal links can be found on the 2009/2010 brief profile proposal wiki page.

The following links are to specific profile proposal discussion pages that support the DPI work:

Design and prototyping activities of the DPI group in 2010 have been mainly concentrated on a use case from the ICE team: Rapid Device Configuration for ventilators in patient transfer scenarios:

Also, though separate from the DPI profiles, the following links are to related profiling activities: <(Note: TBD Discussions>

  • Device Specialization - Physiological Monitor Discussion
  • Device Specialization - Infusion Pump Discusison
  • Device Specialization - Ventilator Discussion

These white paper discussions are also relevant to the DPI work:

  • Medical Device Semantic Architecture White Paper Discussion (Detailed Proposal)
  • Regulatory Considerations White Paper Discussion

Discussion Participants

The DPI working group maintains a Google Group list for all communication during the development of the DPI white paper and subsequent technical framework supplements. The following organizations are currently included in this group:

Action Items

(add newest items to the top of the list)

No. Action Item Owner Participants Due Open/Closed Description/Update
16 Complete draft brief profile proposals Cooper Rhoads / Wittenber 2008.11.11 Open Complete an initial drafting pass at the DPI Brief Profile Proposals (DnA, DR & SYM)
15 External Control Use Cases Jan Wittenber Group TBD Open Flesh out attributes associated with external control ... drudge out of the use cases ...
14 Use Cases supporting Symmetric Communication Todd Cooper Jan Wittenber 2008.10.17 Open In order to evaluate the requirements & roadmap priority relating to a symmetric communication profile, use cases from previous work (e.g., 11073-20302) should be retrieved and added to the DPI use case set.
13 Determine Method for Handling "Transaction Packages" Todd Cooper 2008.10.17 Open DPI profiles such as PnP include dialogs that define a prescribed sequence of messages via a state model / phased conversation. Thus it isn't a single transaction / message but a set of messages. How should this be handled within the IHE framework? Poll IHE co-chairs and other experts to see (a) if this has already been handled, and (b) the best alternatives that we should consider.

Status: Analyzing query response from IHE Co-Chairs

5 2008.10.24 Meeting @ CIMIT 2008.10.02
  • The DPI WG confirmed that a joint meeting with the "ICE" team & MDPnP team should be held at CIMIT (Cambridge Landsdowne Street offices) on Friday, 2008.10.24 immediately after the scheduled IHE PCD F2F meetings in Boston. A key goal should be coordination with the ICE & MDPnP groups.
6 Target 11073-00000 F&0 Content 2008.10.02

8 White Paper Development Process 2008.10.13
  • The PCD shall use the following process for developing the DPI white paper: :::- Brief Profile Proposal (only for a White Paper)
- Detailed Profile Proposal
- Document Development
- Publication for Public Comment
- Publication (with revision history)
9 DPI PoC Definition 2008.10.15
  • For the purposes of IHE PCD & specifically DPI, PoC shall be defined as where the patient is located. Use cases with remote clinicians may also be considered; however, DPI will focus on a patient-centric PoC.
10 Roadmap Priority & Phasing 2008.10.15
  • Initial priority should be on critical care contexts.
  • Number of interface profiles / technologies should be minimized, as appropriate based on the supported use cases.
  • Development of the DPI roadmap should balance between technical feasibility, stakeholder business value propositions, and available resources, maximizing the net benefit.
11 White Paper - Business Value Propositions Section 2008.10.15
  • DPI White Paper should include a section on business propositions - What can DPI provide over other solutions / technologies currently in the marketplace?
  • This should include both vendor and end user value propositions.
12 DPI-PnP Prototyping Focus [[ 2008.10.15
  • DPI-PnP profiling & prototyping should focus initially on...
- Physiological Monitors, Infusion Pumps & Ventilators
- Should be connection oriented
- Should support a LAN architecture (though transport independent)
13 White Paper - non-DPI Transport Use 2008.10.15
  • White Paper should include a use case and discussion regarding the re-use of a DPI PnP transport for non-DPI vendor-specific applications such as configuration or PM servicing and test.
14 "PnP" Clarification 2008.10.17
  • White paper should clarify the description of PnP per the above discussion (esp. the need for pre-coordination).
15 Wireless Connectivity Phasing 2008.10.17
  • Wireless DPI connections will not be addressed in the first prototyping cycle.
16 External Portal Support 2008.10.17
