Detected Issue Severity - 3 concepts, mapped 2 Oct 2018

HL7 ValueSuggested SNOMED TermDiscussion
High24484000 |Severe (severity modifier) (qualifier value)|

These values are inherited from V3. "High" does exist but in a different hierarchy - 75540009 |High (qualifier value)|

Severe does have a synonym of "High Grade"

Should we flag up this apparent inconsistency?

Moderate6736007 |Moderate (severity modifier) (qualifier value)|
Low255604002 |Mild (qualifier value)|

Allergy Clinical Status - 3 values

HL7 ValueSuggested SNOMED TermDiscussion
Active

JR suggests new sub-hierarchy for SCT containing disease activity to align with 370996005 |Patient condition resolved (finding)|

LB suggested use of << 394731006 |Problem statuses (qualifier value)| would need to add "Resolved". YG Notes that these are not in use and their use is not dictated by the MRCM.

DK suggested use of << 36692007 |Known (qualifier value)| again "Resolved" would be required.

Inactive

Resolved

Allergy Verification Status

<< 106230009 |Qualifier for certainty of diagnosis (qualifier value)| doesn't have refuted

Better << 410514004 |Finding context value (qualifier value)|

HL7 ValueSuggested SNOMED TermDiscussion
Unconfirmed410590009 |Known possible (qualifier value)|
Confirmed410605003 |Confirmed present (qualifier value)|
Refuted410594000 |Definitely NOT present (qualifier value)|Also considered 2667000 |Absent (qualifier value)| ? Doesn't really put over that a test was done and the absence of the allergy was proven.
Entered in ErrorNot Found723510000 |Entered in error (qualifier value)| is a 106232001 |Adjectival modifier (qualifier value)| ?

Allergy Intolerance Type

HL7 ValueSuggested SNOMED TermDiscussion
Allergy609328004 |Allergic disposition (finding)|
IntoleranceNot Found - expected for 20190131420134006 |Propensity to adverse reaction (finding)| ?

Outstanding questions

Which descriptions will the free set include - None, FSN, PT (in what languages?)

What if SNOMED Concepts split into more expressive versions ie HL7 code would then map to multiple SNOMED CT codes.
