基于健康等级7的放射学信息系统与影像归档及传输系统集成方法

The radiology information system and picture archiving and communication system integration method based on HL7 standard

目的:对医院放射科信息系统、图像存储系统数据流以及临床工作流进行分析,提出一套系统集成的标准方法,并具体描述各个消息在集成中的作用。方法:遵循医疗企业集成(IHE)框架标准,并基于健康等级7(HL7)数据交换协议,以患者检查为核心,通过使用标准化的消息交互机制,实现了两个独立系统中的各种状态实时交互,满足了临床用户的各种需求。结果:根据多年的实际应用效果,该集成方法取得了满意的效果。结论:通过对标准的深入研究,在医院的临床领域中实现了多系统的无缝集成,既发挥了各系统的优势,也降低了医院采购系统时的成本。

Objective： To analyse the dataflow and clinical flow in Suzhou municipal hospital radiology information system and picture archiving system, presents a set of system integration messages, and describes the effect of each message for the communication. Methods： Follow the framework of IHE and HL7 protocol, the paper uses standard messages to integrate two different systems for patient and study status communication. The integration can meet clinical users＇ requirements. Results： Based on many years practice, the integration reached designed target. Conclusion： With further research on standard, the seamless system integration between different systems can help customer to make full use of each system and save more cost in system purchase.
