Using rxNorm with FHIR
Introduction
On this page, all the rules & semantics for using RxNorm with FHIR are defined.
All of these are defined in terms of the default RxNorm database created (after fixes!) by the scripts provided with RxNorm
Basics
- Namespace is http://www.nlm.nih.gov/research/umls/rxnorm
- both CUI and AUI are valid in this namespace
- The display name is
select Str from rxnconso where RXAUI = :code or (RXCUI = :code and SAB = 'RXNORM')
Filter properties
| Description | Property Name | Property Operators | Value | Comments |
|---|---|---|---|---|
| Type | = | AUI | restrict to only one type -- or should all filters only return CUIs? | |
| STY | in/= | [COL:]Value | default column is TUI | |
| SAB | in/= | Value | value comes from (select RSAB from rxnsab) (e.g. source = RXNORM) | |
| TTY | in/= | Value | value of TTY column in rxnconso |
