[[i2b2 - UHL clinical informatics system integration|back]]

== Source

* The information is stored in the DWEPMA database on the data warehouse server.
* The formulary is based on the First Databank standard.
 * The version in use is not the latest version.
    * The latest version is in test, but there have been problems.
    * It contains the same drugs multiple times for different manufacturers.
* The prescription data does not always contain all the information (dosage, route, frequency, duration) as this may be added by the person who administers the drug.
* Once created, prescriptions are never altered.
    * Incorrect prescriptions are stopped and a new prescription is issued.

== Mapping

* Depending on how closely the formulary sticks to the First Databank standard, it may be possible to use the [http://www.nlm.nih.gov/research/umls/rxnorm/ RxNorm] standard as an ontology or as a way to map the codes to SNOMEDCT.
* Dosage, route, frequency, duration can be stored in i2b2 as modifiers.  This would require i2b2 to updated version 1.6.
