Blockchain-Based Electronic Health Record System for Efficient Covid-19 Pandemic Management

Abstract

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.

Interoperability Requirements for Blockchain-Enabled Electronic Health Records in Healthcare: A Systematic Review and Open Research Challenges

“…e closely related nodes make a cluster. In the network, a node is allocated exactly to one cluster [21,22].…”

Analysis of Blockchain in the Healthcare Sector: Application and Issues

“…Literature affirms that the ever' as well as uncertainty related to today's-increasing complexity and uncertainty related to the increasing complexity and uncertainty related to today's clinical decision situations necessitates healthcare providers to apply the most sophisticated quantitative models that move beyond the general capabilities of the known traditional simple linear models. As the uncertainty and complexity of the data continue to increase, the model's general capability need also needs to equally increase so that the highly nonlinear relationships within the existing variables can also be captured [14]. This is where artificial neural networks and blockchain technologies fit into clinical decisionmaking.…”

Privacy Preservation and Access Control for Sharing Electronic Health Records Using Blockchain Technology

“…Therefore, various blockchain companies such as HealthNautica (HealthNautica, 2022), Factom (FACTOM, 2022, Capital One (Capitalone, 2022) and Gem (Gem, 2022) are collaborating to preserve medical data using blockchain technologies. Besides, many implementations of health data management systems, such as those reported by Qin et al (2021), Zhang and Lin (2018), Pournaghi et al (2020), Li et al (2018) and Alam et al (2021), are emerging. Each application provides various solutions for various conditions.…”
