Karsten, I agree that the medical concepts shhould be carefully modeled first... then extract the necessary terminologies... then build the necessary code lists. I have not wanted to pay the $500 licence fee to look at SNOMED CT, as it will be free for all in 3 months... so I apologize for my ignorance there... but my understanding was the the SNOMED people had already modeled complaints, signs/symproms, diagnosis, treatment plans, prognosis, outcomes... the whole 9 yards. If that is true (seems too good to be true!) then it may only require a (simple??) mapping of SNOMED CT to a collection of EHR Archetypes.
My presumption, given the magnitude of the task of producing such a granular model... not to mention, the massive physician input and necessary vetting, for which there is no efficient mechanism...I am assuming that the SNOMED modeling effort is still at a very high level.of abstraction. Can anyone fill ne in on the present state of this work? SNOMED CT claims to already have "350,000 coded medical concepts", but since it was constructed by a group of pathologists, I am assuming that other care domains are not represented in great detail.
