The Animal Names Terminology Subset of SNOMED CT® Suzanne L. Santamaria, DVM, MS Candidate
Identification Integration Importance increases
Identification of animals is vital • Animal name foundation of medical record • Mixture of Linnaean and common: • Linnaean terminology for scientific names • Class Aves, Bos taurus • Common animal names used by caretakers • Bird, cattle, psittacine bird • Ambiguity in animal names remains • Cattle = Bos taurus? Cattle = Beefalo? Cow? • Cattle = any animal of subfamily Bovinae that is commonly domesticated, varies by country of origin and regulatory authority staring over the fence.
Identification of animals is vital • Electronic recording & transmission increasing • Free text entries problematic • Incompatible standard lists problematic • Need common terminology • between systems and users • integrates both Linnaean and common name • SNOMED-CT determined suitable
Extending SNOMED for veterinary use Veterinary content in SNOMED core is NOT sufficient for clinical or regulatory use SNOMED core updates slowly (q. 6 mo) Veterinary content is low priority Our Solution? – Extension Our lab maintains a veterinary extension Currently used by USDA, AAHA, & AAEP
Implementation in veterinary medicine:Subset mechanism • ALL of SNOMED too large for any given use • Different groups prefer different phrases • Our Solution? – Subset • Update subset as often as desired • Our lab maintains numerous subsets • USDA: Breeds, species, specimens, lab tests, etc. • AAHA, AAEP: Diagnostic terms
Animal names terminology is a starting point Cattle, sheep, goats, pigs, dogs, cats, horses, birds, aquatic animals, zoo animals, wildlife Classified by Linnaean ranking, common name, production use, sex, etc. Integrates with SNOMED core Advantages of SNOMED Subsets allow tailoring for groups Concepts will be added and removed as needs change
Example: Laying chicken Concept Formal definitions Polyhierarchy Descriptions Text definition: Female chicken which produces egg for human food consumption
Each concept has a set of relationships that “define” it • ‘Is A’ relationships form a polyhierarchy • Laying chicken • is a subtype of Gallus gallus AND • is a subtype of Food animal • Other relationships give details • Laying chicken • quality of femaleAND • role of producing eggs for human food
Animal hierarchy adaptable Subfamily Bovinae SNOMED core/extension relationship Optional subset relationship Cattle Bison bison x Bostaurus hybrid Cattle as human food Lactating cattle Genus Bos Bostaurus Bosjavanicus Limousin cattle breed
Example: Dairy bull Formal definitions Subset Preferred Description SNOMED Preferred Description

SNOMED’s power is in its data structure Concept Synonym handling (descriptions) Polyhierarchy Relational/defining mechanism Text definitions, translations History mechanism Extension Subsets
SNOMED is a concept based terminology Concept = an idea which conveys a single, unambiguous, reproducible meaning. Concepts must have a definable meaning (non-vagueness) Concepts cannot have more than one meaning (non-ambiguity) Meanings correspond to no more than one concept (non-redundancy)
SNOMED contains unique and permanent concept identifiers • Meaningless numeric identifier • Guaranteed unique within SNOMED and never reused • Once created, the meaning of a concept does not change • Concepts can be retired but are never deleted/removed! These things maintain the integrity of YOUR information
Introducing Animal Names subset Animal names: Linnaean and common SNOMED’s structure facilitates information organization SNOMED adopted by others Animal names subset specialized for CVM Starting point for an animal names terminology for CVM
Features of Animal Names subset • FDA CVM chooses: • preferred names/phrases • what’s allowed • how terms are defined • what to distribute • Subset grows gracefully over time • Subset will align with other ontologies used in biomedical and clinical research • Subset can be divided: • Approved animal in SPL • MUMS “species” • Adverse event reporting
