Many clinical decision-support applications are created in a centralized manner, but distributed widely for local use. When such applications include queries to electronic patient databases, the queries must be translated to conform to local database specifications. Because no well-defined standard model of clinical data exists, the translation process is ad hoc, costly, and error-prone. In this paper, we propose an abstract formalism, called the Standard Query Model Framework, for specifying a standard clinical data model and for supporting the automated and reliable translation of queries that appear in shared decision-support applications. We present the components of this framework, discuss their desirable features, and describe a prototype that we have developed for relational patient databases. We also highlight the outstanding research issues relevant to our approach.
许多临床决策支持应用程序是以集中方式创建的，但广泛分布以供本地使用。当此类应用程序包括对电子患者数据库的查询时，查询必须进行转换以符合本地数据库规范。由于不存在定义明确的临床数据标准模型，转换过程是临时的、成本高昂且容易出错的。在本文中，我们提出了一种抽象形式主义，称为标准查询模型框架，用于指定标准临床数据模型，并支持共享决策支持应用程序中出现的查询的自动可靠转换。我们介绍了该框架的组件，讨论了它们的理想特性，并描述了我们为关系型患者数据库开发的一个原型。我们还强调了与我们的方法相关的突出研究问题。
