Not certain to get your point here. "Geometrically", a classification is a pavement of a domain (for ICD10, the diseases), each sector being delimited by inclusion and exclusion rules (in the same way frontiers are defined for countries). "Rag bags" (of the kind "other X") are used to fill existing interstices. Hence, every code is by construction exclusive from any other code... and using a classification to "describe" can only come from confusing a point of the domain (say "type 2 diabetes") with the delimited sector that comes with the same name (say, depending on inclusion and exclusion criteria, all hyperglycemia that cannot be qualified as type 1 diabetes). Of course, is it possible to forget all this and use a classification as a lexicon... but that would be plainly evil ;-) Philippe _______________________________________________ openEHR-technical mailing list [email protected] http://lists.openehr.org/mailman/listinfo/openehr-technical_lists.openehr.org
