Orders/Results Technical Committee Meeting Minutes
May 20, 1993 - Boston

The Orders/Results Technical Committee Meeting was led by Dr. Clem McDonald
and Dr. Robert Sidelli.

The status of Chapters 4 & 8 - version 2.2 - were discussed by Dr.
McDonald.  In conjunction with this, the negative ballotting process was
discussed.  It was mentioned that there was one lengthy negative ballot and
that all those that had voted in the previous round would be receiving a
copy of it and have the opportunity to change their vote.

As there were a large number of new attendees to this session, Dr. McDonald
held a question and answer period.  Attendees mentioned that they would
like to be introduced to others who have interest in specific areas, such
as dietary and pharmacy, to discuss implementation problems.

The master file segments for laboratory procedures was discussed.  Dr.
Robert Sidelli was to fill in some holes on field lengths and optionality
for balloting.  The subcommittee voted all in favor with two absentions to
send this section our for balloting as an appendix to chapter 7, with
agreement that if it is negatively balloted the subcommittee would withdraw
it from use with 2.2 rather than hold up the core chapter.

Wayne Tracy proposed that the Orders/Results chapters adopt a trigger event
model like that in the ADT chapter.  There was discussion about the
cost/benefit of this approach.  Specifically, the trigger event model tends
to make the message more atomic and bundling of events (e.g., complex
orders with updates and deletions) becomes problematic.  The general
consensus was that the trigger event modifications would be appropriate for
the 2.x versions and Wayne will bring a formal proposal to the committee at
t he Dallas meeting. [{filename |NORMAL.DOT}]
