Slide 02: The out-of-box i2b2 data model does not appear to match the actual
out-of-box i2b2 data model
https://www.i2b2.org/software/files/PDF/current/CRC_Design.pdf (version
1.6 documentation)
The slide has
* OBSERVER_DIMENSION instead of PROVIDER_DIMENSION
* AGE_NUM instead of AGE_IN_YEARS_NUM
* GENDER_CD instead of SEX_CD
* ETHNICITY_CD does not exist in the out-of-box model
* Missing the MODIFIER_DIMENSION
This also leads into the question of which version of i2b2 will we be
using (1.6, 1.7, or another)?
Slide 03: Why are we deviating from the standard model?
* What is the plan for support for upgrades to i2b2 software?
* Are these variations localized to the GPC or are the consistent across
PCORI?
* Why are we not leveraging modifiers (instead of adding attributes) when
appropriate?
Slide 04: Are the OMB codes the same as the HL7 codes for this information?
* Where can we find the raw data sets for these codes?
Slide 06: What is the plan for when the thing which is making the observation
does not have an NPI?
Slide 07: Are we ignoring professionally coded (billing) diagnosis?
Slide 10: CONCEPT_PATH and CONCEPT_CD do not align as depicted in this slide.
* Multiple CONCEPT_PATHS to one CONCEPT_CD should look something like
this. Only the SNOMED term should have multiple CONCEPT_PATHS because of
poly-hierarchy

* Because of how i2b2 queries its data, we cannot say that each of the
following concepts have the same path unless each concepts ancestors and
dependents also have a 1-to-1 mapping.
Slide 12: How are we calculating the value(s) for INSTANCE_NUM?
