See Spreadsheet attached to: SNOMED on FHIR Meeting (TB) - Tuesday 21 August 2018

Neither of these exist in the FHIR 3.0.1 Spec. @Rob Hausam

Questions:

• What determines which FHIR resource to use: the location of the data item in the sending system’s information model, or the semantics of the particular code regardless of where it was found? Some hybrid of both?

• If the resource to be used is determined at least partly by the location in the sending information model, how does a requesting system cope with the fact that different implementations (or different users of the same implementation) both can and do secrete essentially the same clinical info in very different parts of the host information model?

Next meeting
