电子病历(EMR,Electronic Medical Record)是医疗卫生信息化的重要研究领域,然而目前国内大部分医疗机构正在使用的电子病历系统在很大程度上限制了EMR支持广泛的信息共享等功能的实现,同时,由于EMR中包含患者的一些隐私信息,在实现信息共享中将面临不正当访问获取和隐私信息泄露等问题。本文针对上述EMR应用中存在的问题,提出了基于云存储平台的电子病历系统,实现了数据的共享及可扩展性。 Electronic Medical Record (EMR) is an important research field of medical and health informatization. However, the electronic medical record system currently used by most medical institutions in China largely limits the realization of EMR supporting a wide range of information sharing and other functions. At the same time, due to the fact that EMR contains some privacy information of patients, it will face such issues as improper access and disclosure of private information. In view of the above problems in EMR application, this paper proposes an electronic medical record system based on cloud storage platform, which achieves data sharing and scalability.
