Connectathon planning – deadline is next week

No changes to resources affecting testing (like renaming the Order / OrderResponse resource, but will not be applied by then)

WIKI PAGE LINK Asked Rene Spronk if interested in adding messaging track to this. reviewed actors and test scenario and script

  • Step 1: Create order and then store in order management on EHR-S
  • Step 2: Send the order out to the lab (Rob H is building the lab server to receive the order)
    • Can be a RESTFUL create on the lab server, or could be a message creation
    • Only difference is the endpoint of where the order ends up
    • The LIS then can accept the order or not – that is a second resource = the Order that groups multiple requests for different places – that is the requisition = Order Resource
    • 1 order with 3 things, one 1 can do, 1 for lab B and 1 to lab C – create 2 separate orders, one for each lab
      • Test 1:
        • Order for one test to one source
      • Test 2:
        • Order for one test to one source PLUS the order resource
      • Test 3:
        • Order for more than one test to more than one source

FHIR server is so that it can be shared

  • Server is used as internally storage system – use the client like a browser or between organizations as public entities
  • 1 server for order status = submitted, = completed, = canceled?
  • Accept the order, and then send the result back – match for patient, order number etc.
  • Order to fulfillment system
  • Aim for single server test right now

So far no one signed up for specimen collection – the test case currently ignores the specimen collection

It only becomes a workflow for specimen collection to gather multiple orders to collect the right amount of specimen

Should we still add the requisition (Order/OrderResponse) to the single element order?

  • Not that different when doing the simplest use case

Step 1A – what if the order is not saved somewhere UNTIL it goes out (because the resource is not created until the order is complete?
