Case Study: Aggregation for C2000
• Labs have multiple codes for the same tests
• C2000 displays tests in spreadsheets (“buttons”)
• One code per column per button
• Unrecognized codes go into “Miscellaneous”
• Labs are always adding new tests and not telling
• How do we keep the C2000 buttons current?

Operationalizing C2000 Aggregation
• Translation from lab code to MED code is done by interface engine
• Aggregation from MED code to C2000 button column (“Intravascular …”) is done by interface engine
• New lab tests that fall into existing columns are automatically aggregated
• New lab tests that don’t fall into existing columns can be identified before ending up in “Miscellaneous”

The MED and Eclipsys
• Capturing data from ancillary systems
• Aggregation for summary reporting
• Keeping terminologies up to date (e.g., for order entry)
• Class-based decision rules
• Multiple hierarchies allowed
• Linking to on-line resources
