Comment (by campbell):
Bret Gardner and I tested several rounds of i2b2 query development against
our database. I reviewed clinical records to refine the accuracy. Bret
has posted the i2b2 query print on Babel and I enclose a zipped copy (web
archive page format) with this ticket. I have edited in the coded
valuesets (ICD9CM, ICD10CM, ICD10PCS, RXNORM, SNOMED CT and LOINC) for all
relevant criteria.
This posted version of the i2b2 query yielded a false positive rate of
2/25 (8%) that was due to the fact that we do not have med reconciliation
data stored in i2b2 yet. Those sites that have such data should be able
to do better. I also found 2/25 cases where I think the clinician was
on shaky ground when they recorded that the patient had a heart attack,
but I chose not to second guess the healthcare provider for this
validation round.
