“…This can be seen during the COVID crisis where an older demographic is more at risk, but still may need medications that need to be picked up from a pharmacy. Allowing a trusted third party to access their account would overcome this problem, while still maintaining confidentiality for the individual user ( 21 ).…”

Objective Healthcare systems suffer from a lack of interoperability that creates “data silos,” causing patient linkage and data sharing problems. Blockchain technology’s unique architecture provides individuals greater control over their information and may help address some of the problems related to health data. A multidisciplinary team designed and tested a blockchain application, MediLinker, as a patient-centric identity management system. Methods The study used simulated data of “avatars” representing different types of patients. Thirty study participants were enrolled to visit simulated clinics, and perform various activities using MediLinker. Evaluation was based on Bouras’ criteria for patient-centric identity management and on the number of errors in entry and sharing of data by participants. Results Twenty-nine of the 30 participants completed all study activities. MediLinker fulfilled all of Bouras’ criteria except for one which was not testable. A majority of data errors were due to user error, such as wrong formatting and misspellings. Generally, the number of errors decreased with time. Due to COVID-19, sprint 2 was completed using “virtual” clinic visits. The number of user errors were less in virtual visits than in personal visits. Discussion The evaluation of MediLinker provides some evidence of the potential of a patient-centric identity management system using blockchain technology. The results showed a working system where patients have greater control over their information and can also easily provide consent for use of their data. Conclusion Blockchain applications for identity management hold great promise for use in healthcare but further research is needed before real-world adoption.

“…Blockchain can modernise the electronic health record exchanges by delivering a secure approach for medical data exchange of medical data in the field of healthcare productiveness, by safeguarding it through a dispersed peer-to-peer linkage. The Blockchain approach is proposed to provide sustenance and comfort to the procedure for understanding the dispersed technology of ledger [23]. Advances in this innovative blockchain technology have steered to provide transactions in a better way, including insurance billing, health records, and smart contracts.…”

Electronic Health Record (EHR) is being used in most healthcare institutions to preserve and share health records instead of a paper-based method. Data records must be exchanged amongst various parties and users' privileges to manage access to their records should also be provided. In addition to the basic standards of secrecy, confidentiality and integrity of information, these facts further demonstrate the need for interoperability and consumer control to access their personal data. Electronic Health Record (EHR) system faces issues of protection of data, trust and management issues. In recent Covid-19 pandemic, various applications, tools and websites were launched that stores records. Also, many personal records related to health need to be shared among different parties for early detection, contact tracing, monitoring and the future prediction that requires accurate and reliable data. Simultaneously, the citizens will be hesitant in providing their personal details due to privacy concerns and social stigma. Blockchain technology has arisen as a powerful technology that can offer the immutability, confidentiality and user access properties of stored information and provided distributed storage. This paper analyses the blockchain suitability in EHR and its further applications in efficient Covid-19 pandemic management.

“…There are currently several approaches regarding EHR management and how blockchain technology can be utilized to improve it [20,21]. Yüksel et al [6] discussed the distinction of EHR storage between distributed and cloud design, and propose that a centralized model could be established by applying the relevant decentralized settings and techniques of the cloud architectures.…”

Electronic health record (EHR) management systems require the adoption of effective technologies when health information is being exchanged. Current management approaches often face risks that may expose medical record storage solutions to common security attack vectors. However, healthcare-oriented blockchain solutions can provide a decentralized, anonymous and secure EHR handling approach. This paper presents PREHEALTH, a privacy-preserving EHR management solution that uses distributed ledger technology and an Identity Mixer (Idemix). The paper describes a proof-of-concept implementation that uses the Hyperledger Fabric’s permissioned blockchain framework. The proposed solution is able to store patient records effectively whilst providing anonymity and unlinkability. Experimental performance evaluation results demonstrate the scheme’s efficiency and feasibility for real-world scale deployment.
