基于医院医疗区块链平台的EMR设计与实现

EMR Design and Implementation Based on Hospital Medical Block Chain Platform

针对电子病历(EMR)在安全策略和访问控制模型方面结构不一致的问题,提出了一种基于区块链的智能合约医疗平台来实现EMR的安全管理。该方法为患者提供了全面、不变的日志,并可以方便地跨医院内不同部门访问其医疗信息。经实际应用,建立了许可网络,并进行了一系列实验测试,验证了所设计平台的可用性和有效性。通过各种性能指标进行了基准研究,所设计的平台在各个方面都具有极大的潜力,可以加速分散式数字医疗生态系统的发展。

Advances in information and communication technology are driving major changes in electronic health research and industry.In the case of personal medical data sharing,data security and convenience are key requirements for electronic medical record (EMR) system interaction and collaboration.However,it is difficult for current systems to meet these requirements because of their inconsistent structure in terms of security policies and access control models.To solve the above problems,an intelligent contract medical platform based on block chain is proposed to realize EMR security management.This method provides a comprehensive and constant log for patients,and can easily access their medical information across different departments of the hospital.Taking a hospital as an example,a license network was established and a series of experimental tests were conducted to verify the usability and effectiveness of the designed platform.The benchmarking study through various performance indicators shows that the designed platform has great potential in all aspects and can accelerate the development of decentralized digital medical ecosystem.
