Electronic medical records (EMRs) are critical, highly sensitive private information in healthcare, and need to be frequently shared among peers. Blockchain provides a shared, immutable and transparent history of all the transactions to build applications with trust, accountability and transparency. This provides a unique opportunity to develop a secure and trustable EMR data management and sharing system using blockchain. In this paper, we present our perspectives on blockchain based healthcare data management, in particular, for EMR data sharing between healthcare providers and for research studies. We propose a framework on managing and sharing EMR data for cancer patient care. In collaboration with Stony Brook University Hospital, we implemented our framework in a prototype that ensures privacy, security, availability, and fine-grained access control over EMR data. The proposed work can significantly reduce the turnaround time for EMR sharing, improve decision making for medical care, and reduce the overall cost.
电子病历（EMR）是医疗保健领域至关重要且高度敏感的私人信息，需要在同行之间频繁共享。区块链提供了所有交易的共享、不可变且透明的历史记录，以构建具有信任、问责制和透明度的应用程序。这为使用区块链开发安全且可信的电子病历数据管理与共享系统提供了独特的机会。在本文中，我们阐述了对基于区块链的医疗保健数据管理的观点，特别是关于医疗保健提供者之间的电子病历数据共享以及研究方面。我们提出了一个用于癌症患者护理的电子病历数据管理与共享框架。与石溪大学医院合作，我们在一个原型中实现了我们的框架，该原型确保了电子病历数据的隐私性、安全性、可用性以及细粒度访问控制。所提出的工作可以显著减少电子病历共享的周转时间，改善医疗护理的决策制定，并降低总体成本。
