Abstract: 

A detailed electronic record of delivered clinical care is important for providing clinical decision support and for conducting research using existing clinical data. Knowing the type of document filed within an EHR (e.g., bronchoscopy report), helps to derive important procedural or phenotypic information that may not be obtainable from other sources. A comprehensive document ontology can also greatly facilitate review of clinical documents integrated from multiple sources within a health information exchange (HIE) platform. The Clinical LOINC (Logical Observation Identifiers Names and Codes) terminology includes a Document Ontology (DO) that is intended to provide a standardized set of document types. We analyzed the frequency of clinical document types from the National Institute of Health's (NIH) Clinical Center as mapped to LOINC DO. Our work complements prior work with results from a research-oriented healthcare institution, and has implications for LOINC developers as well as EHR system administrators.
