Construction of an Interface Terminology on SNOMED CT Generic Approach and Its Application in Intensive...
Objective: To provide a generic approach for
developing a domain-specific interface terminology on SNOMED CT and to apply this
approach to the domain of intensive care.
Methods:The process of developing an interface terminology on SNOMED CT can be regarded as six sequential phases: domain
analysis, mapping from the domain con -
cepts to SNOMED CT concepts, creating the
SNOMED CT subset guided by the mapping,
extending the subset with non-covered concepts, constraining the subset by removing
irrelevant content, and deploying the subset
in a terminology server.
Results:The APACHE IV classification, a standard in the intensive care with 445 diagnostic
categories, served as the starting point for designing the interface terminology. The majority (89.2%) of the diagnostic categories from
APACHE IV could be mapped to SNOMED CT
concepts and for the remaining concepts a
partial match was identified. The resulting initial set of mapped concepts consisted of 404
SNOMED CT concepts. This set could be extended to 83,125 concepts if all taxonomic
children of these concepts were included. Also
including all concepts that are referred to in
the definition of other concepts lead to a subset of 233,782 concepts. An evaluation of the
interface terminology should reveal what
level of detail in the subset is suitable for the
intensive care domain and whether parts
need further constraining. In the final phase,
the interface terminology is implemented in
the intensive care in a locally developed terminology server to collect the reasons for intensive care admission.
Conclusions: We provide a structure for the
process of identifying a domain-specific interface terminology on SNOMED CT. We use this
approach to design an interface terminology
on SNOMED CT for the intensive care domain.
This work is of value for other researchers who
intend to build a domain-specific interface
terminology on SNOMED CT
