Simple Lab Order Flow

Simple Lab Order Workflow with a single Glucose (LOINC 2345-7) Test

Important Information

• This is a minimal viable definition of a possible laboratory workflow
• This is not implementable for now but tries to show the flow of the order and the minimal needed information

Assumptions

• Physician knows which Sample to draw (i.e. via an Order Catalog)
• Specimen is drawn at the Physician office
• It is clear which Order Filler will execute the Order
• ServiceRequest is owned by the Order Placer; changes are allowed only to be done by Placer
• Task is a shared resource of Placer and Filler and updated by both
• Order Result is reported via DiagnosticReport
• DiagnosticReport is owned by the Order Filler
• Order will be accepted and fulfilled
• Lab internal flow is out of scope
• All needed data is accessible
• All needed data around the Sample is in the Specimen like collection related information (Procedure, collection date/time, body Site, …)

  Not defined

• Ownership of Specimen Resource (Ownership should/could/might change with the physical location - this should be defined in a more detailed Lab IG build on the COW principles)
• Transport of the Sample
