Nathan The scope of ICD* includes items such as "injury from motor vehicle accident" (E codes), "past history of diabetes"(V codes), "family history of rheumatic fever"(V codes) which are not diagnostic events in the SNOMED concept model. For all "Diagnoses" retrieved from out Clarity problem lists and billing diagnoses, these items will have a slightly different access path in the SNOMED concept dimension. We should probably discuss with the group what would provide most pragmatic access for our research community.
We agreed at Hackathon to prioritize SNOMED work to a later step and so there is no hurry to come to a conclusion on this issue Jim ________________________________ From: Wilson Nathan [[email protected]] Sent: Friday, March 14, 2014 10:19 AM To: Campbell, James R Subject: RE: Top level ontyology for i2b2 Hi Jim, Thanks for sharing, some comments below.. ICD9CM: OK SNOMED-CT Clinical Findings: OK SNOMED-CT Events: This has not been discussed or mentioned until now (to the best of my recollection), how are you thinking that the GPC sites would implement this information? From UW-Madison’s perspective we would need to create a mapping of our EPIC diagnosis IDs to SNOMED Event IDs and I do not believe that we can undertake such an effort at this time. SNOMED-CT Past History: The group had talked about using a modifier on the diagnosis codes to indicate Past Medical History. SNOMED-CT Family History: This has not been discussed or mentioned until now (to the best of my recollection), how are you thinking that the GPC sites would implement this information? My concern is again for similar reasons as SNOMED-CT Events, although the set of information is small so it would be more possible. Lab Tests look fine Clinical Measurements are fine Procedures, Orders, and Medications: I known that we haven’t talked discussed this much as a group, but it may also be possible to use Modifiers to distinguish amongst the ordered and performed procedure as well as the ordered and administered medication. When we talk about medications we may also want to include dispensed medications as well (again possibly as a modifier to medications).
