循证医学数据库信息模型的语义结构构建

Construction of semantic structure for information model of evidence-based medicine database

通过分析医务人员需求、调研循证医学相关标准和数据库,建立了循证医学数据库信息模型的文献特征、诊疗过程和证据强度三维顶层结构模块,并在顶层模块下表达了更加细化概念的数据组和数据元,规范了数据元表达的概念属性等等级语义结构。结果证明,采用模块化的方法构建循证医学数据库信息模型语义结构,能更好地管理和组织临床文献,使医务人员能更好地检索和利用循证医学信息。

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 semantic 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.
