Reviewed minutes from 2008.10.15

       Ken - Avoid usage of PnP? e.g., MDPnP folks, over used - more confusing than helpful
       Jan - also there is ALWAYS some level of configuration / pre-coordination to make it ... PnP 
                IOW - may never be achievable
                e.g., -30300 A/P had pre-coordination IP addresses 
       Ken - Break it into the "self ID" part of the protocol ... reporting ... configuration ...
                OR Discovery & Association
                OR Data Reporting  (or Data Reporting Polled & Data Reporting Asynchronous)
                OR Bi-directional Information Exchange
                OR External Control 
WP - include description of PnP (clear definition) + need for pre-coordination
        "CLC" (closed loop control) may be similarly overloaded & misunderstood (a la real-time)


3 Wireless & Device/Patient Pairing
- Group
  • ...


       may have two radios (short & long range)
       may be manually entered
       Need to look at different layers of the problem ... technology dependent / independent
       ICE spec "nasty" is ... adding into an environment w/o disrupting other devices
       Must be secure, include contextual awareness, etc. ...

WP - Including section in white paper ... but may need to be addressed in subsequent phases

Thursday - Include wireless u/c & archicture discussion w/ Phil Raymond

Action(s): Enterprise Application vs. Deployment architectures

<used Ken's latest diagram to beg the question...>
       BCMA can be 
                Enterprise functions or 
                VeriScan is a stand-alone system
       What does "enterprise" mean?
       What does DPI mean? 
                DPI "PoC" 
                         Must be patient connected
                         DPI is focused on FIRST communication hop...
                "full blown hospital information system"
                Speciality systems (e.g., infusion pump management systems / gateways)
                         May have a single function BUT do so across all the enterprise

Action(s): DPI

       Multiple concurrent connections must be supported
                Device communication systems are not disconnected with each other 
       Portal vs. local "persistent" connections
      • Need to address multiple paths to the "enterprise" for the same device info (specialized servers vs. general gateway)
       Where would a lab system go? 

In the F2F, need to see if we can come up with a model that will clearly communicate the differences between these perspectives and the PCD TF (as well as other IHE TFs).

Action(s): DPI-PnP =>

        DPI-Discovery & Association
                Device connecting into a "PnP" network
                Discovery of other patient connected devices (incl. Schluter's nurse PDA discovering & commuicating with connected devices)
       DPI-Data Reporting
        DPI-Bi-directional Information Exchange
                Device Pairing / discovery of devices & information with same patient
                Wired - port oriented / pairing operation
                Wireless pairing
        DPI-External Control
                Open Loop
                Closed Loop 
                         Device reporting local settings for display on a monitor or central station for clinician review (a la PIV "closing the loop")
                         Changes to controls w/o clinician intervention (algorithmic)
                         Fully automated control communication 
                         Semi-automated control communication (human in the loop to complete the process)
                Safety Interlocks
                         ??? Never involves clinician activation???
                Alarm silence
                         Open loop control
                U/C Arith. algo on Central ... linked to bed ... comm is broken ... 
                         Must be "closed loop"
                TO DO:  Flesh out attributes associated with external control ... drudge out of use cases ...  
       DPI - Real-time Archival [and retrieval] Management    "flight recorder"
       DPI - Application Server Platform ???
                Ability of a device to request / receive / be notification re. download of an algo / code to be run on device 
                *** Drudge out use cases for this
                Put device in "standby" mode for communication purposes (e.g., to save battery)
                Poll for device asset management functions (a la MEM)
