目标
信息管理的任务之一是对医院信息系统（HIS）进行系统规划。然而，对HIS的当前状态的描述和分析通常产生高成本并且没有得到很好的支持。因此，本文的目的是报告有关规范的参考模型的域层的医院信息系统。
方法
基于医院信息处理的需求指标描述企业功能，基于HL 7-RIM中的对象类型描述实体类型，建立了医院信息系统领域层的参考模型。
结果
所开发的参考模型是医院信息系统企业功能的综合层次模型。例如，中央企业功能“患者治疗”在三级层次结构上用35个企业功能和38个实体类型来描述。
讨论
参考模型提供了一种建模模式，可以很容易地使用和适应各自的信息系统。因此，参考模型的可用性应该提供一个非常有价值的贡献，以保持成本低的医院信息系统建模。我们将开始评估的参考模型，使用它在描述的信息系统的大学诊所的Tiroler Landeskrankenanstalten有限公司（TILAK），奥地利。如果这项预先测试的结果是肯定的，则计划将参考模型的使用扩展到TILAK的整个医院信息系统。
OBJECTIVES
One of the tasks of information management is systematic planning of a Hospital Information System (HIS). However, the description and the analysis of the current state of a HIS typically create high costs and are not well supported. The aim of this paper is therefore to report about the specification of a reference model for the domain layer of a Hospital Information System.
METHODS
We developed a reference model for the domain layer of a Hospital Information System based on the requirements index for information processing in hospitals for describing the enterprise functions, and based on the object types from the Health Level 7 Reference Information Model (HL7-RIM) for describing the entity types.
RESULT
The developed reference model is a comprehensive hierarchic model of the enterprise functions of hospital information systems. The central enterprise function "patient treatment" for example is described with 35 enterprise functions and 38 entity types on a three-level hierarchy.
DISCUSSION
Reference models provide a kind of modelling patterns that can easily be used and adapted to a respective Information System. The availability of reference models should therefore provide a highly valuable contribution to keep the costs for modelling Hospital Information Systems low. We will start to evaluate the reference model by using it in the description of the information systems of a University Clinic of the Tiroler Landeskrankenanstalten GmbH (TILAK), Austria. If this pre-test is positive, it is planned to extend the use of the reference model to the overall Hospital Information System of the TILAK.
