Blockchain-based electronic health record system with patient-centred data access control.

This study examines the application of blockchain technology in addressing the increasing prevalence of mental health issues among young adults in the UK. Despite the recognition of the potential of digital health solutions and mental health apps by healthcare organizations and professionals, many individuals are hesitant to share sensitive information due to security concerns. To address this, the study proposes utilizing blockchain technology to create a patient-centred, transparent system for data access control that adheres to the General Data Protection Regulation (GDPR) and established security protocols. The research includes the development of a proof-of-concept decentralized web application, which incorporates a modified scrum methodology, test-driven development, clearly defined security requirements, and design patterns for security and gas optimization. The study concludes with an evaluation of the application, insights from automated security analytics, and recommendations for future research.
