Once the work of the Cooperative Agreement is completed, users o=
f each terminology will receive added benefits.
LOINC Benefits to SNOMED CT Users
- LOINC codes will provide to SNOMED CT terminology extensive coverage of=
clinical laboratory tests and some types of clinical measurements. Likewis=
e, the addition of SNOMED CT concepts from LOINC Parts will expand coverage=
in areas like substances, cell types, kinds of property, etc.
- LOINC provides greater granularity and specificity for coding of labora=
tory tests.
- Links between the terminologies will promote the usage of SNOMED CT by =
LOINC large global community.
- The Observables model related to clinical lab tests in SNOMED CT was ba=
sed on the LOINC semantic model.
Additional benefits of linking SNOMED CT and LOINC are described in refere=
nced papers written by Adamusiak and Bodenreider referenced at the end of t=
his Chapter. [
SNOMED CT Benefits in Laboratory Area for LOINC =
Users
Linking LOINC terms to the SNOMED CT subtype hierarchy and description l=
ogic definitions provides an inferred hierarchy for LOINC terms. Some of th=
ese benefits were described by Adamusiak and Bodenreider (referenced at the=
end of this Chapter), including:
- SNOMED CT is currently being used in the laboratory area for reporting =
Microbiology results. Linkage to related LOINC codes provides a more integr=
ated pattern of usage in this domain.
- The richness of SNOMED CT relations can provide novel insights into the=
original resource
- The hierarchy of parts used by LOINC terms can be informed by the SNOME=
D CT hierarchy, thus reducing duplicative work
- Hierarchical organization of LOINC terms can be inferred automatically<=
/li>
- SNOMED CT relationships can also provide enhanced subsumption for LOINC=
terms. New paths are not limited to abstract observations that group LOINC=
codes, but also LOINC codes themselves can be in direct relationships. Thi=
s limits the need for creating abstract observations to group them.
- The SNOMED CT DL representation can enhance navigation among LOINC term=
s by providing access to more paths between the codes in the SNOMED CT hier=
archy. Such navigation can make it easier to find an appropriate code.
- SNOMED CT DL can also enhance curation of LOINC content by enabling det=
ection of duplicates and missing hierarchical relations.
