title: Ambient Findability: Developing a Flowsheet Ontology for i2B2.
abstract: The process of moving from the locally defined flowsheet ontology containing redundancy and jargon to one understandable by researchers is described. Over 250 million nursing flowsheet observations were imported into a data repository that uses the i2b2 framework. Focus groups were used to derive a new ontology model--18 templates were identified. One hundred measures, 50% of all patient observations over 36 months, were encoded in SNOMED CT(©). 78% of the concepts were mapped.
