RE: Follow up: Clinical Observations Interoperability Telcon @ Tue Oct 30


Thanks for your response. After reading your message carefully, I realized that
you are heading into the heart of the issue related to the interrelationship
between an information model and a terminology.

At some level, the approach taken by the SDTM is similar to the approach
taken by the DCM folks. The commonality is that a structure/class is modeled to
represent a Vital Sign and then a code from a controlled terminology is inserted
to give meaning to that data structure. The difference is that SDTM
models an abstract class called VSTEST and DCM models each of these vital signs,
such as BloodPressure as different classes. This actually will lead
to changing the spreadsheet. Will send it to you after I update it. Some other
comments are inserted inline.

> Slide 1-3 visualise the concept structure in NCIt for Diastolic Blood
Pressure, Pregnancy Test and Postpartum Hypertensions  
> - Slide 1: the concept with the preferred term Diastolic Blood Pressure as a
sub-concept of Personal Attribute.
> - Slide 2: the concept with the synonym Pregnancy Test as a sub-concept of
Laboratory Procedure.
> - Slide 3: the concept with the preferred term Postpartum Hypertensions as a
sub-concept of Finding.

VK> This is interesting as each of the concepts and relationships in the NCI
terminology have to be aligned with each of the classes in the DCM model and the
concepts in Snomed as well. This alignment has to be at the global rather than
the local level.
