Ticket #1246 (closed problem: fixed)
Approximately 2% of Medication Facts are Not Covered by our VA Med Hierarchy

Around 12% of all medication facts from Clarity don't map to a medication concept in the new VA hierarchy. This means that the end-user cannot see these medications in the ontology and therefore cannot perform any queries to access 12% of the medication facts.
The ideal goal would be to match 100% of the medications found in Clarity to a location in the VA hierarchy. That way, all medications (and subsequently all medication-related facts) would be available to the end-user. 100% coverage is likely unrealistic, but we believe there are ways to improve coverage such as:
- Medex - natural language processing to match medications by name http://knowledgemap.mc.vanderbilt.edu/research/content/medex-tool-finding-medication-information
- Normalization of NDC codes found in Clarity as per example code from NLM.
As per #1048, we have implemented a medication ontology based on VA Drug Class (NDF-RT) and the RxNorm Semantic Clinical Dose Form. This approach is based on this 2010 paper on mashing up RxNorm and NDF-RT hierarchy.
- Some of the SCDFs have very long text strings (see ticket:1048#comment:41). Right now we truncate, but there may be a better way to abbreviate).
