Welcome to the homepage for the RxNorm VISTA/RPMS Support. I am Sam Habiel, and I am the developer for these packages. I can be reached at sam dot habiel at gmail dot com.
NB: Documentation for the older version of RxNorm can be found at RxNormForVista0.02.
What is RxNorm?
RxNorm is a standardized vocabulary set for Drugs in the United States. The goal of RxNorm is drug nomenclature standardization and systems interoperability. More information on RxNorm can be found at http://www.nlm.nih.gov/research/umls/rxnorm/.
Why do I want this?
RxNorm is necessary for interoperability with other systems. If you use VISTA alone without having to talk to any other system, then you don't need RxNorm. However, if you perform external drug interactions, send CCDA documents, or archive patient records for CCR, you are going to need RxNorm. For Meaningful Use, you are required to have RxNorm for various purposes.
What does this release contain?
This release contains Fileman files corresponding to most of public domain RxNorm (archived data is not loaded into VISTA). It also contains utilities for querying RxNorm for specific information and a utility to add drugs to the drug files automatically based on an RxNorm number.
It's important to note that the public domain RxNorm files here differ from the NLM prescribable subset of RxNorm. While both are public domain, the prescribable subset does not contain the VA datasets that enable translation between VISTA and RxNorm. These are available in the full RxNorm package from the NLM. Public domain corresponds to UMLS Restriction Level 0. Read further below to see how to get proprietary codes into your data file like First Databank GCNs and SNOMED codes.
How much does this cost?
This release is licensed under AGPL v3.0 and is free as in free beer. A commercial license for commercial entities running VISTA can be obtained for $2000 per VISTA instance; the commercial license can be found here: RxNormForVista/CommercialLicense. Support costs for monthly updates are $100/month per VISTA instance both for AGPL and commercial users.
How can I install RxNorm on VISTA/RPMS?
Before you install
YOU MUST READ THIS BEFORE INSTALLING
The RxNorm globals file is about 2.5 GB, and when loaded it takes up about 2.5GB. You therefore need to have at least 10 GB available on your drive.
It is very highly recommended that you load and maintain RxNorm in the ^C0CRXN global in an UNJOURNALED portion of your Mumps Database. The data is reproducible and does not need to be journaled; and journaling it is very expensive in terms of journal size. In addition, once loaded, it will not change until the next load. Maintaining back-ups of your database will be easier this way.
RxNorm contains very long text values. You must ensure that your Mumps database can do at least 16,000 characters in a single global node.
On GT.M V6.0, create the following Global File Definition, and run it with GDE:
add -segment C0CRXN -file="/path/to/your/globals/c0crxn.dat" -allocation=200000
-block_size=4096 -lock_space=100 -extension_count=1000 -global_buffer_count=8192
add -region C0CRXN -record_size=16384 -key_size=255 -dyn=C0CRXN
add -name C0CRXN -region=C0CRXN
If you use GT.M less than V6.0, you must make sure that your block size and record size synchronize since GT.M couldn't span blocks then.
On Cache, create a new database, and map ^C0CRXN to it. By default Cache databases allow 32K of global node length.
Installation
As of version 0.02 (the current version is 2.2), the installation method has changed. You now install the dictionary file (which you need to only install once unless it changes) and then install the data file, which changes month to month. The data installation now takes 30 minutes to 60 minutes since it is transported as globals.
Installation Order:
- DD and routines: source:ccr/trunk/rxnorm/tags/2.2/RXNORM_FOR_VISTA_2P2.KID
- Public Domain Data (unzip with 7z first): source:ccr/trunk/rxnorm/tags/2.2/RXNORM_FOR_VISTA_PD_DATA_11P2013.GKID.7z
Installation is a normal KIDS file installation. There is nothing special about it.

What can I do with RxNorm
User Mode use
All files are shipped with no file access code security for reading, and as such they can be read by all users if they are granted access to Fileman and don't have Kernel Part III security turned on. If Kernel Part III security is turned on, you will need to grant users access to files 176.001 through 176.006. If you don't know what Part III security is, then you don't have it.
Concepts
Users can query the Concepts file by typing the concept name (usually a drug generic name or brand name) or a drug code (such as a VUID). Here are a couple of examples:
Search for all entries that have the word PROZAC in them:
Select RXNORM CONCEPT NAMES AND SOURCES RXCUI: PROZAC
1 PROZAC 58827 MSH PEN D005473 Prozac
2 PROZAC 58827 RXNORM TMSY 58827 PROzac

According to this, RxNorm was last updated with VA sources on September 27th 2013. An SRL of 0 means that the source is public domain.
Relationships
RxNorm relationships are not easy to query in this version due to Fileman not behaving well with compound B indexes. But they are doable if you know what you are searching for.
Let's find out the generic drug concept that corresponds to the RxNorm code we obtained via the NDC for Prozac 20mg:

The Semantic Clinical Drug entry (SCD) for RxNorm means that we hit the jackpot: That is indeed the canonical generic entry for the branded Prozac 20mg capsule.
Programmer APIs
Update API
To update RxNorm to a newer monthly version from the NLM, run the following:
D IMPORT^C0CRXNRD("/path/to/rrf/folder/",optional include restricted/copyrighted sources (1 -> yes). Default is no.)
If you need FDB or SNOMED-CT codes, you need to pass in the second parameter.
Look-up APIs
This is a list of APIs available for programmers for converting one terminology to another. Some APIs return multiple results. If so, they will be delimited by "^".

C0CRXNLK comes with Unit Tests. To run them, make sure M-Unit is installed and run ^C0CRXNLK from the top.
Automatic Drug Addition API using RxNorm
To add a drug to the drug file using the RxNorm CUI, call the following entry point:
W $$ADDDRUG^C0CRXNLK(RXNCUI for Drug, optional NDC to file, optional barcode to put for BCMA)
Please note that this routine does not check to see if the drug is already there; it will add it again.
This routine can be enhanced to use the barcode to figure out which drug it is that is being added from RxNorm. As such, it will enable you to add drugs to the drug file by just bar-code scanning them.

Security
This software implements no security of its own beyond Fileman access codes on the fields which can be seen below in the File Structure section. None of the data contained is sensitive in any way.
File Structure
All files have only a zero node for each entry and correspond as much as possible to the RxNorm file format, except that the '|' has been substitued with a "^". The exception to that rule is when a file's first field cannot be the .01 because it's missing for some entries. In this case, the first field and a key field are switched so that the key field can be the .01.

A crucial part of speed in the RxNorm operations is the extensive indexing on the files. What follows are the defined new-style indexes:
NEW-STYLE INDEX LIST -- FILE #176.001 11/21/13 PAGE 1
-----------------------------------------------------------------------------------------------------------------------------------
File #176.001
New-Style Indexes:
B (#983) FIELD REGULAR IR LOOKUP & SORTING
Short Descr: Regular B Index
Set Logic: S ^C0CRXN(176.001,"B",X,DA)=""
Kill Logic: K ^C0CRXN(176.001,"B",X,DA)
Whole Kill: K ^C0CRXN(176.001,"B")

Short Descr: Code Index
Set Logic: S ^C0CRXN(176.001,"CODE",X,DA)=""
Kill Logic: K ^C0CRXN(176.001,"CODE",X,DA)
Whole Kill: K ^C0CRXN(176.001,"CODE")
X(1): CODE (176.001,.14) (Subscr 1) (forwards)
STC (#1021) RECORD MUMPS IR LOOKUP & SORTING
Short Descr: Source Term Type Code Index
Description: Use this index to do compound searches on RxNorm Concepts.
Examples: SAB="NDDF", TTY="CDC", CODE={GCN} will give you the entry a clinical drug in First Database with GCN
Code {GCN}.
SAB="RXNORM", TTY="SCD", CODE={RXNORM} will give you the entry that is the Semantic Clinical Drug for the
RxNorm code.
SAB="VANDF", TTY="CD", CODE={VUID} will give you a drug that has that VUID.
Set Logic: S ^C0CRXN(176.001,"STC",X(1),X(2),X(3),DA)=X(4)
Kill Logic: K ^C0CRXN(176.001,"STC",X(1),X(2),X(3),DA)
Whole Kill: K ^C0CRXN(176.001,"STC")
X(1): SAB (176.001,.12) (Subscr 1) (forwards)
X(2): TTY (176.001,.13) (Subscr 2) (forwards)
X(3): CODE (176.001,.14) (Subscr 3) (forwards)
X(4): RXCUI (176.001,.01) (forwards)
STR (#1022) FIELD REGULAR IR LOOKUP & SORTING
Short Descr: String Lookup Index
Set Logic: S ^C0CRXN(176.001,"STR",$E(X,1,30),DA)=""
Kill Logic: K ^C0CRXN(176.001,"STR",$E(X,1,30),DA)
Whole Kill: K ^C0CRXN(176.001,"STR")
X(1): STR (176.001,.15) (Subscr 1) (Len 30) (forwards)
Transform (Storage): S X=$$UP^XLFSTR(X)
Transform (Lookup): S X=$$UP^XLFSTR(X)
STX (#1023) RECORD MUMPS IR LOOKUP & SORTING
Short Descr: Source Term Type RxCUI Code Index
Description: Use this index as a reverse of the STC index.
The STC index will give you an entry if you know the source, the type and the code. This index will give you
the codes if you know the source, the type, but not the code, but rather the RxNorm code.
Set Logic: S ^C0CRXN(176.001,"STX",X(1),X(2),X(3),DA)=X(4)
Kill Logic: K ^C0CRXN(176.001,"STX",X(1),X(2),X(3),DA)
Whole Kill: K ^C0CRXN(176.001,"STX")
X(1): SAB (176.001,.12) (Subscr 1) (forwards)
X(2): TTY (176.001,.13) (Subscr 2) (forwards)
