基于IHE的移动医疗信息集成研究

Research on Mobile Medical Information Integration Based on IHE

移动医疗服务是基于移动计算的模式,在网络和医疗信息系统基础上产生的一种新型医疗服务模式。移动医生工作站是移动医疗服务平台的一个重要系统,需要与HIS、LIS、PACS等其他医疗信息系统进行数据交换与共享,但是这些系统可能基于异构的数据库平台、操作系统平台,也可能用不同的语言开发,所以在这些系统之间存在"信息孤岛"。现有的医疗信息集成标准不能适应这些系统之间的信息集成。本文首先分析了移动医生工作站与LIS、PACS的数据交换过程;其次,介绍了IHE技术框架,分析了基于IHE PIX的病人身份识别过程;最后,分析了基于IHE PIX和XDS临床文档信息共享的过程。基于IHE PIX和XDS集成框架的移动医疗信息集成方法不仅可以跨不同的临床信息域,而且可以跨不同的医疗机构解决异构的医疗系统集成问题,对提高医疗服务效率和质量都有重要意义。

The mobile medical service is a new model of medical service based on mobile computing model, network and medical information systems. The mobile medical workstation is an important system of mobile medical service platform. The system requires data exchanging and sharing with HIS, LIS, PACS. But these systems may be based on heterogeneous database platforms and operating system platforms, and may also be programmed in different languages. So there are ＂information isolated island＂ between these systems. The existing medical information integration standard can not be applied to the information integration between these systems. This paper firstly introduces the concept and the function of the mobile medical workstation, and analyzes the data exchange process of mobile medical workstation with LIS, PACS. Secondly, the paper introduces the technology framework of IHE, and analyzes the process of patient identification based on IHE PIX. Finally, the paper analyzes the process of clinical documentation information sharing based on IHE PIX and XDS. The method can not only help share clinical documentation information between different clinical information domains, but can also help solve the integration problem of heterogeneous medical information systems between different medica institutions. It is very significant for improving efficiency and quality of medical services.
