I agree with all, most of the terms are difficult to be translated to archetypes. What it is possible using snomed is to specify the valuesets of a given data element by using the snomed expression constraint syntax. We have been experimenting with it for a while, we have even put an execution engine online. http://snquery.veratech.es/
Another idea to achieve what you want (which is something that some countries are doing and HL7 also does but with Loinc) is to extend the terminology in order to provide new codes with a meaning of exactly the archetype element meaning (or CDA template/FHIR resource). These come in an extension, so not all that interoperable, but al least you could bind the archetype to something 2016-04-29 18:40 GMT+02:00 Bert Verhees <[email protected]>: > On 29-04-16 18:02, Ian McNicoll wrote: > > Hi Bert, > > "I think that every leaf-node in an Archetype can be encoded in SNOMED, > don't you think?" > > I'm afraid not even close, especially when you take into account the changes > in the meaning of datapoints that apply when used in differing contexts. > When doing modelling for histopathologym I was not even close to getting 50% > binding of SNOMED to archetype leaf-nodes, ands histopath is one of the > better covered parts. > > > Leaf-node datapoints should not have much context.
