Following Russ' question on the call today, while it may be that cancer 
chemotherapy would be some of the highest cost admixtures, reviewing stats from 
our database shows that of the 1500 custom admixtures prepared by UNMC 
pharmacy, frequent cases reflect antibiotics, hormones and fluid/electrolyte 
preps.  Thinking about retrieval use cases we have discussed with GPC 
bariatrics, the antibiotics as individual ingredients stand out as one item we 
were struggling to manage recently

Subject: Mapping Medication Mixtures

We found that some of our ordered medications are not mapped by GCN to rxnorm 
using the shared mapping script.  It turns out that these medications are 
actually mixtures of medications that use a mixture template to order them.  
The data for what is actually in the med order ends up in the order_medmixinfo 
table.  For example:
"XXX Chemo Infusion" from the medication order turns out to be "XXX Chemo 
Solution" + "Overfill Volume for IV Infusions" + "Sodium Chloride 0.9% IV".

We have a simple generic code associated with the primary medication but I'm 
not seeing how to convert get that to an RXNorm Code. The "XXX Chemo Solution" 
does map to RXNorm.  But the ingredients in the template associated with the 
medicine id also can change over time.  In the case above, the template went 
from 2 to 3 ingredients at some point. I believe the filler was added to the 
mix.  But that indicates that they are not static templates which further 
complicates the mappings process.

I'm considering using the simple generic code to find another similar 
medication and then taking it's ingredients for my mapping.  Another 
alternative would be to use the medmixinfo to create 3 new observations in i2b2 
which represent the 3 components of the mixture.

Has anyone else looked at this?

Phillip
