• Remember to record!

• Recording!!!

SNOMED CT - LOINC cooperation

• Presentation of LOINC alpha release phase 3*
• Expectations and use cases for the LOINC-Term SNOMED CT expressions*
• Discussion and resolution of issues(*)
• Discussion of LOINC panels as orderables and deployment in SNOMED CT

Farzaneh Ashrafi

See Farzaneh's slide set. Alpha release phase 3 feedback due by May 31st 2016.

Questions:

Jim Campbell. Are the terms there also?
Scott Campbell:Terms are integrated in the release.
JC> Numbers? FA About 14,000 terms representing about 70% of lab terms.

LOINC Mapping Issues Slides

Mapping X+Y concepts.
DK> Subsumption is affected whenever modeling multiple components.
DK> These are disjunctions not conjunctions.
JC> Is it true there are individual as well as panel for each of the components?
DV> Yes

JC> We can manage it better if we create an enumeration - a series of observations. e.g. in a separate ref set.
DV>  Not all of these are panels, some are tests that cannot distinguish between the components with a Positive/Negative result.

DK> This is the same problem as Total Amino acid and more specific amino acids issue, because we don't have disjunction in SNOMED. We could push the problem to substances.

FA> Electrolytes as substances e.g. Sodium is a cation, Chloride is an anion. Model to the electrolyte or to the parent substance?
MO / RD others>  It appears correct to model to the more specific substance i.e. the electrolyte.

Cancer check list*

• Identify any critical issues
• Inform IPaLM/Observables group on model deployment in anatomic pathology

James R. Campbell

Scott Campbell

Molecular pathology*

• Present current UNMC approach with specific, deployed examples
• Discuss the model as deployed and attempt to reach a consensus for the approach
