Copyright © 2001 College of American Pathologists Concept Inter-relationships for Disorders SNOMED CT uses relationships between concepts to provide logical, computer readable definitions of medical concepts. These relationships, which can be hierarchical or non- hierarchical, enable health data to be re-used for decision support, outcomes analysis and clinical research.

Copyright © 2001 College of American Pathologists The “Is a” Relationship The “Is a” relationship is used to create a hierarchical relationships between concepts, relating specific concepts to a more general category. For example: “Pulmonary tularemia” “Is a” (kind of) “Tularemia”
Copyright © 2001 College of American Pathologists The “Finding site” Relationship The “Finding site” relationship identifies the part of the body affected by the specific disorder or finding. For example: “Pulmonary tularemia” (has) “Finding site” “Lung structure”
Copyright © 2001 College of American Pathologists The “Causative agent” Relationship The “Causative agent” relationship identifies the direct cause of the disorder or finding. The causative agent is the bacterium, virus, toxin or environmental agent that causes the disorder. For example: “Tularemia” (has) “Causative agent” “Francissella tularensis”
Copyright © 2001 College of American Pathologists The “Associated morphology” Relationship The “Associated morphology” relationship identifies the abnormal physical condition that is characteristic of a given disorder or finding. For example: “Pneumonia” (has) “Associated morphology” “Inflammation”
Copyright © 2001 College of American Pathologists The “Laterality” Relationship The laterality relationship specifies the side of the body that applies to an anatomy concept. Procedures, findings and disorders can have laterality by qualifying their site (procedure-site or finding-site). For example: “Left kidney” (has) “Laterality” “Left” “Cyst of left kidney” (has) “Finding site” “Left Kidney” “Biopsy of left kidney” (has) “Procedure site” “Left Kidney”
