Modern healthcare systems have two main sections: electronic health records (EHRs) and remote patient monitoring (RPM). With these sections, several issues have arisen related to comprehensiveness, which these sections lack in covering all the data information about the patient’s state, and other issues in privacy and security. Many types of research have been presented to solve these issues or mitigate their effects. One of these ideas is to use blockchain technology. However, some research may not utilize this technique properly, where data comprehensiveness problems remain and the preservation of individual nodes' data may be compromised. This paper introduces a new system called Patient Health Record (PHR), which will provide comprehensive patient health data and IoT device reading. PHR data is protected using a multi-peer, distributed, and decentralized system based on blockchain. A smart contract has been created for the system through which the PHR data will be cached in the blockchain. It is deployed on the Proof of Authority network to increase the speed of transaction processing, which is important in processing data for IoT devices. The proposed system is evaluated according to a range of metrics (cost, immutability, data storage, and estimated time) to validate the system.
