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. Follow this link to see the relationship types applicable to finding and disorders.
Relationship Types for Disorders Clinical Attributes • Finding Site • Causative Agent • Associated Morphology • Laterality Hierarchical • Is a
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”
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”
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”
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”
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”
