This page is not the terminology that we use on this web site, but rather, the list of clinical terminologies used with our software. Other pages contain our SHARPn Term Glossary.


SNOMED is a systematically organized computer processable collection of medical terminology covering most areas of clinical information such as diseases, findings, procedures, microorganisms, pharmaceuticals etc. It allows a consistent way to index, store, retrieve, and aggregate clinical data across specialties and sites of care.
ICD The ICD is the international standard diagnostic classification for all general epidemiological, many health management purposes and clinical use.
RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, MediSpan, Gold Standard Alchemy, and Multum. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.
NDF-RT, or the National Drug File Reference Terminology organizes drug lists into a formal representation. NDF-RT is used for modeling drug characteristics including ingredients, chemical structure, dose form, physiologic effect, mechanism of action, pharmacokinetics, and related diseases. NDF-RT is part of the Federal Medication Terminologies (FMT).

Common Terminology Services

The second revision of the Common Terminology Services standard (CTS2) is an important artifact in building the software to meet the goals of the SHARPn collaboration. For a closer inspection of this important specification, including value set handling, please see the CTS2 web site.
