Recording + Notes.

Christmas Break: 25 Dec + 1 January

Rob's Birthday.

Next meeting on 15 January will collide with HL7 Meeting in San Antonio.

Potential for face to face meeting at the April Conference

@Jane Millar

@Peter Williams

Sunday is the only option.

What is the enthusiasm for a Sunday slot - afternoon slot so US attendance vial dial in feasible.

Daniel in person, Peter + Rob dial in.

Free SNOMED CT Set for FHIR

Jane update re meetings with Keith (VA) and Wayne (HL7)

Free SNOMED CT set for FHIR

• Are the mappings suggested complete and ready as a recommendation?

Exemplar Profile

@Daniel Karlsson

Publishing Profiles

• Wrapped by implementation guide - in this case https://github.com/IHTSDO/snomed-ig

• Value set publish to a live SI hosted Snowstorm instance. Alternatively @michael lawley has offered to host.

• Additional hosting on Simplifier (STU3, not yet R4 - January?)

• Suggestion to review work already done to ensure R4 compatibility

• Would value sets also be published as reference sets? Maintain via Refset tool and published in MLDS. Note: UK experienced substantial 'getting off the ground' effort in this area. Sweden have worked through ~10 (will request promotion of content to International Edition where appropriate).

• Option to have multiple profiles available at the same time using slicing.

• Chance to do some technical work at HL7 San Antonio

Allergies

@Daniel Karlsson

Revisit any outstanding questions on Allergies.

Vital Signs

X

@Daniel Karlsson

Vital Signs Resource

Jeremy's work to compare Vital signs profile and SNOMED Subhierarchy - issues with eg blood pressure. Complex expression constraints available which cover the use of observables by the NHS(UK). Mapping to LOINC codes.

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

Issues / Discussion :

• Normative vs. descriptive purpose - 1, 2, or 3 profiles?

• Unresolved modeling issues
  
  

v3.0.1

ProcedureRequest

ReferralRequest

v3.4.0 (publication Aug 19?)

ServiceRequest

@Daniel Karlsson

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

http://build.fhir.org/servicerequest.html → ServiceRequest

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?
