基于SOA的医院信息系统集成平台建设与思考

医院各信息系统间的信息共享与业务协同是目前医院信息化建设面临的主要问题。分析目前医院信息系统建设现状，提出面向服务架构（SOA）的医院服务总线（HSB）的集成方案，为医院信息系统实现松耦合的集成提供平台。基于HL7、IHE、CDA、DICOM等标准建立各个系统与平台之间交互的消息机制，将系统的各种功能以服务的形式提供给最终用户或者其他服务，以实现医院各信息系统间的信息共享与业务协同。

Construction and Study on the Hospital Information Systems Integration Platform Based on SOA

Information sharing and business collaboration among different hospital information systems have become the major challenges faced by the hospital informationization progress at present. Based on the analysis of the current construction status quo of hospital information systems, the hospital service bus （HSB） integration plan based on service oriented architecture （SOA） is proposed in this paper to provide the platform for realizing the loosely coupled integration of the hospital information systems. With information exchange system built between different systems and the platform in accordance with the integration plan and HL7, IHE, CDA, and DICOM standards, all the functions of the systems are materialized by means of providing services to the terminal users or other service systems. Therefore, the information sharing and business collaboration among different hospital information systems can be achieved.
