ABSTRACT

A 3-dimensional top level structure module of literature characteristics, diagnosis and treatment process, and evidence level was established respectively for the information model of evidence-based medicine ( EBM) database by analyzing the demands of medical staff and investigating EBM-related standards and databases. The data sets and elements with their concepts subclassified were expressed under the top level module, and the se-mantic structure of data elements-expressed concept attributes was standardized, which showed that the semantic structure of information model for EBM database that was constructed with modularized method can help medical staff to manage and organize the clinical literature, retrieve and use the EBM information more effectively.
