Abstract: Taking a hospital in Sichuan Province as an example, in allusion to the problems existing in medical record management, this paper studies the innovative design and effect evaluation of medical record management system based on block-chain technology. The methods of questionnaire survey, interview and experiment are adopted. Through the data comparison between the old and new systems and the hospitals at the same level, the new system based on block-chain technology can greatly meet the functional and non-functional requirements of hospital medical record management. It is proposed to further improve the informatization construction; improve the comprehensive quality of medical record management personnel; establish perfect medical record management regulations to protect the legitimate rights and interests of patients, doctors and other system related personnel; establish suggestion on performance evaluation system.
Keywords: Block-chain technology; record management system; electronic medical record
0 引 言
目前我国医院面临着业务量持续增长和属性复杂化,由此医院病案管理系统的升级换代也已成必有之势[1]。虽然大部分医院已完成了病案管理系统的初级建设,但仍存在诸多不足,比如病案管理系统安全性存在重大隐患、病案数据收集整理功能不全、检索病案管理困难、数据分享无有效的身份识别机制、医疗记录无法追踪溯源等,而区块链技术恰好能解决这一系列问题。
1 基于区块链技术的医院病案管理系统的特点及应用优势
区块链是一种具有去中心化、不可篡改、可追溯等特点的分布式账本[2]。区块链技术基于密码学原理,利用哈希函数、分布式共识算法等,保证了系统的安全性。Hyperledger Fabric是区块链中联盟链的一种实现,由成员服务、区块链服务和链码服务三个部分构成,其特点是支持可插拔的共识机制且实现了完备的权限管理,最适用于医院病案管理。……
