New Research Tool: Using the RxNorm System

Tools for ResearchA new research tool available on the Living Textbook provides an overview of RxNorm and explores the application of some of its associated tools in the research setting. RxNorm is a free, publicly available resource from the National Library of Medicine that provides “normalized” names and unique identifiers that make it possible to clearly identify a given drug. This allows information about medications to be exchanged across electronic health records (EHRs). In fact, the Office of the National Coordinator designated use of RxNorm as a criterion for EHR certification of interoperability and Stage 2 Meaningful Use.

The explanatory resource was developed by Michelle Smerek of the NIH Collaboratory’s Phenotypes, Data Standards, and Data Quality Core. Feedback is encouraged to help expand this tool.
