目的建立区域医疗信息数据共享平台,实现电子病历、医学影像等区域医疗数据共享,完善个人健康档案,提高医疗服务水平。方法借鉴国内外相关研究成果和经验,对现有医疗信息化资源进行虚拟化改造,并利用SOA、Web服务等技术建立基于云计算的区域医疗信息数据共享平台,连接医疗机构之间异构的信息系统。结果提出一种基于Web服务的数据交换云平台设计方案,使用加密和压缩的XML技术来进行数据交换及保证数据的安全和私有性,研制的原型系统在多家军队医院部署运行,实现了临床信息的共享。结论云计算平台具有便于动态扩展、分布式共享和泛在接入等特性,将其应用于区域医疗信息化有较高的可行性和实用性。
Objective To establish a regional medical information and data sharing platform to achieve regional medical data sharing such as electronic medical records and medical images, improve personal health records and improve the level of medical services. Methods Learning from the relevant research results and experiences at home and abroad, the existing medical informatization resources were virtualized and rebuilt. Based on technologies such as SOA and Web services, a cloud computing-based regional medical information and data sharing platform was established to connect heterogeneous Information system. Results A data exchange cloud platform design scheme based on Web Services was proposed, which used the XML technology of encryption and compression to exchange data and ensure the security and privacy of the data. The prototype system was deployed in a number of military hospitals to realize the clinical Information sharing. Conclusion Cloud computing platform has the characteristics of being easy to expand dynamically, distributing sharing and ubiquitous access. It has higher feasibility and practicability for regional medical informatization.
