【摘要】 为了用信息技术支持卫生干预分类(Classification of Health Interventions,CHI)标准的实施,该文从构建CHI编码信息系统的目标出发,研究了CHI的信息模型。建模研究从最抽象的本体模型开始,经基于面向对象的UML(unique modeling language)模型,到最终面向数据管理的ER(entity-relationship)模型,完成了面向CHI的多层次信息建模。基于建模结果,建立了一个卫生干预分类数据库,将现行多个CHI标准导入并建立之间的关联,为最终形成支持基于CHI标准的服务与操作编码,及与之相关的医疗决策与管理的信息系统打下基础。更多还原

【Abstract】 Health Intervention Classifications(CHI)request efficient coding information systems,various information models have better developed for CHI,including a conceptual ontology model,an Object-Oriented UML(unique modeling language)model,and an ER(entity-relationship)model.This work describes a multi-level CHI information model used to create a database with a large amount of data from the various prevailing standards.A mapping mechanism among the standards within the database is also given.The results of this study can assist CHI coding procedures and provide a base for the final IT system implementation that focuses on supporting decision-making in medical management.更多还原
