A rationale for parsimonious laboratory term mapping by frequency
Mapping local observation codes to a standard vocabulary provides a bridge across the many islands of data that reside in isolated systems, but mapping is resource intensive. To help prioritize the mapping effort, we analyzed laboratory results reported over a thirteen month period from five institutions in the Indiana Network for Patient Care. Overall, more than 4,000 laboratory observation codes...
Toward the creation of an ontology for nursing document sections: mapping section names to the LOINC semantic model
Clinical documents consist of groups of information (e.g., sections, panels, batteries). In order for clinical information to be shared, consistent formal naming principles for document components are desired. The purposes of this study were 1) to identify the components of existing electronic nursing documents, and 2) to represent them with Logical Observation Identifiers, Names, and Codes (LOINC) semantic model to...
Document ontology: supporting narrative documents in electronic health records
Electronic health records (EHRs) are beginning to manage an increasing volume of narrative data, such as clinical notes pertaining to admission, patient progress, shift change, follow-up, consultation, procedures, etc. These documents fall into a wide variety of classes, based on who is writing them, for what purpose, and in which location, suggesting the need for a document ontology (DO) to...
The Creation of an Ontology of Clinical Document Names
The efficient use of documents from heterogeneous computer systems is hampered by differences in documentnaming practices across organizations. Using an openconsensus method, the Document Ontology Task Force’, with support from the Veterans Health Administration, addressed this pervasive problem by developing a clinical document ontology. Based on the analysis of over 2000 clinical document names, the ontology was used to formulate...
