  • Title: Looking for Anemia (and Other Disorders) in SNOMED CT: Comparison of Three Approaches and Practical Implications.
    Author: Mougin F, Bodenreider O, Burgun A.
    Journal: AMIA Annu Symp Proc; 2010 Nov 13; 2010():527-31. PubMed ID: 21347034.
    Abstract:
    Health professionals are faced with challenges when they have to exploit the semantics of concepts present in clinical terminologies in support of research activities. The difficulty lies in the fact that this semantics is represented not only through the labels of concepts, but also their position in the hierarchy, and, when available, their logical and textual definitions. We investigate and contrast the lexical, hierarchical, and logical representations of concepts in SNOMED CT through the example of Anemia and three other disorders. The four use cases we developed suggest that the lexical, hierarchical, and logical representations of concepts have a limited degree of overlap, but are complementary. Finally, we draw practical implications from our findings for SNOMED CT users and developers.
