Peter G. Williams

SNOMED Expo Oct 31 - Nov 1 Kuala Lumpur

Thursday half hour session. Title of session: "SNOMED on FHIR" Content: Profiles (eg Allergy Intolerance), Free Set, Implementation Guide, discussing and sharing.

Terms that are returned when requesting implicit valuesets. Snowstorm returns FSN, Ontoserver returns Preferred Terms.

ML: Intention is that this list would be used to populate a resource and so the PT is appropriate "The best display is the preferred". DisplayLanguage parameter should be used for the client to specify what they want - how would we use that for FSN vs PT vs Other (eg Patient Friendly Terms)?

Designation parameter should be used to recover the FSN (pulls from Designation Use ValueSet)

• Rob Hausam add to agenda for discussion (Designation Use ValueSet) in Atlanta (Sept)
• Peter G. Williams rework Snowstorm to return PT by default and FSN as additional designation when designation parameter is present

Group's current interpretations is that includeDesignations=true (with no other designations specified) would return all designations whereas specifying the specific designations is a request to return those specific designations.

Note for Vocab group that although 900000000000548007 |Preferred (foundation metadata concept)| exists, we do not ( ?) have a concept to represent patient friendly terms.

Note issue with licence restrictions in ValueSet. Tracker needed to remove text -

• Reuben Daniels to raise tracker.
• Jane Millar to note that additions to this ValueSet would require adding << 900000000000511003 |Acceptability (foundation metadata concept)|
  
• Peter G. Williams add to agenda for KL

****************

• ALL Pitch in to Implementation Guide for using SNOMED CT with FHIR

*******************

Rob Hausam Please add documentation on running updated tooling.

Progressing the SNOMED Implementation Guide and specific guidance of "Best Practice" of using SNOMED with FHIR. Can we include tests for 'correctness' - using existing FHIR Testing platforms?

https://github.com/IHTSDO/snomed-ig with the built view hosted by GitHub at https://ihtsdo.github.io/snomed-ig/

Tooling: Current tooling appears to be solely command line based. See also Snapper for value set editing (currently STU3).

• Peter G. Williams reference hosted build in Readme.

What is the scope of content for the guide? Targeting "Best Practice" for FHIR Implementers using SNOMED CT. Possible layered approach and potentially strict (for internal record keeping and communication) vs permissive profiles when . General guidance for bindings or specific details on each resource.

Audiences - Developer vs User of implemented services. ML Suggests single entry point document with multiple paths through the documentation.

8 January 2019 Update:

Tooling: Forge (doesn't support R4)

• Peter G. Williams install Simplifier
  
• Rob Hausam suggest road map for where our focus should be. Pull in CodeSystem Resource page?
  

What do we want to say about how SNOMED should be used in FHIR? Eg On the Terminology Services side, start with a narrative and head towards a test script where a particular query is expected (formally) to return a given set of results. Then on the resource side, talking about what particular value sets should be used for specific resources - condition code being a high value. Will we insist that these are SNOMED code or could they be proxy codes eg where a medication is given on a problem list and - in it's presence - indicates the underlying condition but without specifying that explicitly.

Start with a Confluence page for collaborative work and once that's reached some stage of maturity it can be moved into the GitHub repository in a more structured form.

Are we looking at one implementation guide or two? Terminology Server vs Terminology Binding and Profiles.

• Peter G. Williams Rob Hausam to bring SI's IG into line with current tooling expectations.

Mechanisms for working with Languages

Michael Lawley has raised ticket about the "use" field being limited to FSN/Synonym. Elsewhere in FHIR there is a "display" code that can be used to indicate other languages See 22490. Also 19960 - additional term for "Consumer Terms" ready for implementation R5 (Q4 2020 at the earliest).

18 June PWI gave some notes from pop-up session at FHIR Dev Days - more about locale than language. ML: "Translation" extension doesn't allow for a particular piece of text being in a different language from that of the resource.

Next meeting 13 August
