New types of patient health records aim to help physicians shift from a medical practice, often based on their personal experience, towards one of evidence based medicine, thus improving the communication among patients and care providers and increasing the availability of personal medical information. These new records, allowing patients and care providers to share medical data and clinical information, and access them whenever they need, can be considered enabling Ambient Assisted Living technologies. Furthermore, new personal disease monitoring tools support specialists in their tasks, as an example allowing acquisition, transmission and analysis of medical images. The growing interest around these new technologies poses serious questions regarding data integrity and transaction security. The huge amount of sensitive data stored in these new records surely attracts the interest of malicious hackers, therefore it is necessary to guarantee the integrity and the maximum security of servers and transactions. Blockchain technology can be an important turning point in the development of personal health records. This paper discusses some issues regarding the management and protection of health data exchanged through new medical or diagnostic devices.

提高医疗保健效率：EHR，IoMT和区块链的可能作用

新型的患者健康记录旨在帮助医生从通常基于其个人经验的医学实践转向循证医学之一，从而改善患者与护理提供者之间的沟通并增加个人医学信息的可用性。这些新记录允许患者和护理提供者共享医疗数据和临床信息，并在需要时随时访问它们，可以被视为启用环境辅助生活技术。此外，新的个人疾病监控工具可支持专家完成其任务，例如允许采集，传输和分析医学图像。对这些新技术的兴趣日益浓厚，对数据完整性和事务安全性提出了严峻的问题。这些新记录中存储的大量敏感数据肯定会吸引恶意黑客的兴趣，因此有必要保证服务器和事务的完整性和最大安全性。区块链技术可能是个人健康记录开发中的重要转折点。本文讨论了有关通过新的医疗或诊断设备交换的健康数据的管理和保护的一些问题。
