title: PTXT Finder - an application for finding appropriate EHR data elements for data analysis using cross referencing information sources.
abstract: PTXT Finder was developed to reduce the manual efforts necessary to map from clinical variables in a decision support system to data elements in an EHR. The descriptions in a data dictionary may be inadequate for pinpointing data elements that represent a clinical variable. Semantics implied in taxonomy and real usage of the element are two important supporting information sources. PTXT Finder provides description, hierarchy, and statistics displays so users can cross-reference among these views.
