Patient Monitoring System using Blockchain and IoT Technology

Abstract

Background: Recently, the construction of a smart city has accelerated due to developing technologies such as 5G and the Internet of things (IoT). The IoT is gaining access day by day in the area of the remote monitoring system. Along with smart city concepts, intelligent patient monitoring systems and intelligent health are being developed. Combining the two, here, patients have a nurse navigation system and a doctor emergency call system. IoT improves the effectiveness of medical equipment by providing real-time monitoring of patient health, in which sensors collect data from patients with less human errors. In IoT, the patient's parameters get transmitted through medical devices via a gateway to the centralized system, where it is stored and analyzed. Objective: In this paper, we have proposed an intelligent patient monitoring system for monitoring the patients' health condition automatically through sensors-based connected links. The system is more intelligent that it can be able to detect the critical condition of a patient by processing sensor data and instantly provides a notification to doctors/nurses as well as hospital in-charge personnel. The doctors and nurses get benefited from this system by observing their corresponding patients remotely without visiting to the particular seat of the patient. Methods: An idea has been proposed to use the centralized processing of IoT devices along with the rigid security and privacy of the classical blockchain to overcome the computation expense challenge with blockchain and the security and privacy threat of the IoT systems. We are developing a system in the field of medical care to enhance the functioning of Medicare systems and provide patients with more ease and hassle-free procedures of the Medicare system, i.e., hospitals, laboratories, dispensaries, chemists, druggists, etc. Results: This model helps in getting rid of this issue faced by all of us. There is a separate blockchain of different verified medical stores linked within the networks, which will be managed by the central hub based on their ratings, reviews, and stock availability. Conclusion: The exponential expansion of blockchain technology in healthcare is also astonishing and has a tremendous impact on the industry. By assessing prior activities, the idea is proposed to use a centralized database system with more privacy and security to gap between the healthcare industry and blockchain technologies has been addressed in this paper.
