  • Eric to coordinate time between OO, PC, and Pharm to discuss transfusion medicine (looking to see if can use PC time slot Thursday 5 Eastern)
  • Eric to schedule meeting with FMG to discuss the overlap with Media and Observation + ValueAttachment (Media still owned by FHIR-I decision to move to OO or Imaging delayed by the boundaries issues)

Rikis notes:

Eric, Dan discussion: order result pairs we use in v2 - when to use diagnostic order instead of obseervation - because we need to next observations and diagnostic orders - not sure how importannt the 
slide 3: orgnaism panel and susceptibilty panel are orders in lab perspective
both observation and diagnostic report can refernrece the order (basedOn)
Change word "panel" - since panel does not have results

all observation are referenced to the order that spwaned that - need to back up the chain of resources

add explantion to the diagram what each box means
and how each of these link back to the orders they come from

structure needs to be there s well as the data elements needed to represent that
orders would be separate boxes in this diagram

the diagnostic report should retain the structure of the panels that the lab performs
each of the arrows mean something - like what parent result this is related to, or what order it comes from - this is built on LRI model

Rob has some examples he can share those and add 

will add the legend to these slides 
motion is to put one example of each of these approaches into the specification 
against:1, abstain: 0, in favor: 4 

Eric, Rob, Dan R, Dan A, Andrea, Riki, Elliot on the call

idea to get this as argonaut project for 2017, but may be next time...
get input from Danielle

queries for results, but not really how the push works yet, so let v2 go as is

can always use QT datatype that can be used as integer and count datatype can do that - so do not like to have 2 ways of doing the same thing
