4 General Term Development Discussion
- Group 		Status/Discussion:
  • Paul reiterated that the group should focus on (in priority order): reported monitored parameters, reported settings ("read only configs"), Waves, ..., Alarms, Control parameters . In other words, in order to make the problem set more tractable, the universe of possible parameters should be organized by application data type.
  • The order/priority should be based on what clinicians want to see on their charts!
  • NOTE: In the case of an "index", the underlying arithmetic expression or at least some of the key properties should be identified (e.g., "...per BSA")
  • Steven reiterated the need to focus on the clinical purpose for which the data is being collected. For example,
1. For the HIS/Charting
2. Research purposes
3. Forensics ("black box")
  • Question: Is there a way of indicating the intended "purpose" of the parameter (e.g., by including "setting", or "monitor" etc.)?
                ??? Is there a way of indicating the intended "purpose" of the parameter, e.g., by including "setting" / "monitor"
                         at the start of the term so that the goal can be quickly determined?
                Re. index formulae - this can be specified / formalized in the vent OR in an external information system.  Should 
                         accommodate both.
       (Paul)
                Could combine Observation & Settings under the same set of yellow columns ... as a TYPE of data
                Could add discriminator re. the use of the parameter
                For indicies - maybe a reference to the liturature

        (Dain)  Airway pressure - where measured?
                (Paul) indicate measurement site information
                         (Dain) is this the role of the device or the CIS?  (sometimes in machine / sometimes by clinician /
                                  sometimes by clinician entered into device...)
                (Ken) measurement method also important (optional attribution ... but should be available)
                (Jan) adding a methodological column would be very helpful (transductive <Functional> statistical)

       Rosetta (Paul)
                Add another column "RefID 2" as a working space
                (Jan) take the key terms from the rosetta to identify what we should target as a first order priority

       Steve - What are clinicians actually recording on charts today?  We should factor in workflow as a key factor
                toward prioritization of what is supported.

        <thc> How to capture & factor in workflow w.r.t. terminology
                Jan:  Terminology vs. information model
                Todd:  Heuristics re. when this clinical context information is folded into the term vs. in the info model?

        ["stat" - ??? <don't have a clue what Jan meant> ]

       episodic / "spot" measurements vs. continuous trends - should also capture this class of numeric data (episodic & continuous)

       Why differentiate between episodic & continuous?  Paul:  the information is handled / communicated differently ... IOW 
                data handling / management

Decisions/Issues:

Action(s):

5 Planning Discussion
- Group 		Status/Discussion:
  • There was a general discussion regarding the group's strategy for going forward.

Decisions/Issues:

  • Complete core mindmap of semantic architecture
  • Focus on numeric parameters (esp. what is charted...) first
  • Update table:
- Add functional discriminator column (e.g., energy per breath, indexed per BSA, body weight)
- IOW 5th row discriminators ... next set of columns (min / max / ...)
- Observation & Setting same YELLOW color
- Support "measurement site" (pre/post coordination)
- Add a "clinical" column
  • Update RTM tables with "RefID 2" column + "measurement site" column

Action(s):
