Historically Comprehensive Medications Metadata for i2b2 Data Warehouses

In the U.S., the Office of the National Coordinator guidelines recommend using the RxNorm controlled medical vocabulary for clinical drug orders and National Drug Codes (NDC) for dispense and administration events within electronic health records (EHRs) (1, 2). Use of RxNorm to index and track medication events supports clinical research data needs for medications. The terminology is updated frequently to include new medications and remove discontinued drugs. To maintain current and historically accurate medication data, methods are necessary to manage RxNorm updates within research data warehouses.
