Precoordinated primitive terms•Whenever a pre-coordinated concept isavailable, that should be the first choice. Ifthe pre-coordinated concept is a primitiveconcept, an alternative is to create a postcoordinatedexpression to ensure thenecessary semantics are recorded. Thereason is that terms encoded with primitiveconcepts are more difficult to query andtest for equivalency (Lee, 2010).
Linkage concepts in Pathology• The concept “histological grade (attribute)” is a linkageconcept.• There are some special concepts, like attributes (e.g.246229000 | histological grade (attribute)), that can beused as “linkage concepts”:• Question: 371469007 | histologic grade (observableentity),246229000 | histological grade (attribute)• Answer (values):370114008 | histological grades (qualifier value):384812005 | moderately differentiated263843001 | poorly differentiated263918006 | undifferentiated263933003 | well differentiated
