Using rxNorm with FHIR
Revision as of 16:44, 6 July 2014 by GrahameGrieve (talk | contribs)
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
- CUIs are valid in this namespace
- should AUIs be valid too?
- The display name is
select Str from rxnconso where (RXCUI = :code and SAB = 'RXNORM')
- or maybe select Str from rxnconso where RXAUI = :code or (RXCUI = :code and SAB = 'RXNORM')
Filter properties
| Description | Property Name | Property Operators | Value | Comments |
|---|---|---|---|---|
| Identifier Type | Type | = | AUI | restrict to only one type -- or should all filters only return CUIs? |
| Semantic Type | STY | in/= | [COL:]Value | default column is TUI |
| Source | SAB | in/= | Value | value comes from (select RSAB from rxnsab) (e.g. source = RXNORM) |
| Term Type | TTY | in/= | Value | value of TTY column in rxnconso |
