Comment (by astoddard):
MCW has not implemented the PCORnet CDM build from i2b2 (i2p-transform).
We are not alone in this. Non i2p-transform sites will all likely have
higher costs for getting PCORnet/ SCILHS / ARCH modifiers properly aligned
in i2b2.
Going without modifiers we can expose the diagnosis ontology in SHRINE
trivially within a few days.
I estimate implementing the modifiers for diagnosis in our i2b2 is a week
of dedicated work for MCW. Scheduling that with existing priorities, the
need to bring new team members up to speed, and coordinating with internal
data release schedules means actual availability of PCORnet modified
diagnosis queries in MCW Shrine is likely to be early Jan 2018.
There remains some ambiguity to resolve on PCORnet /ARCH / SCILHS modifier
use - eg. the PDX axis which is "Principle Discharge Diagnosis" in CDM3.x
and defined to only be relevant to inpatient encounters but is called
"Primary Diagnosis Flag" in the ontology itself and could be expected to
apply more widely as a result.
Even i2b2 deployments that sit upstream of PCORnet CDM builds may not have
modifier use perfectly aligned, the CDM spec itself is vague at times, and
I would be unsurprised if some post-processing of CDMs will have happened
in order to pass data-checks.
MCW's preference is to make un-modified SHRINE ontology queries available
across procedure and diagnosis domains early and then improve on that.
