This fascinating book delves into the transformative role that blockchain technology could play in the security and integrity of patient data within the healthcare sector. In an era where data breaches and privacy concerns loom large, blockchain has emerged as a potential solution to these challenges, offering a route to streamline healthcare processes, manage data and improve patient outcomes. The book begins by providing a comprehensive overview of its underlying principles, including decentralization, immutability and consensus mechanisms, before exploring, through a range of international cases studies, how blockchain has been applied so far within the healthcare sector, from the management of electronic health records (EHRs) and clinical trials to medical billing and supply chain management. The authors also explore the barriers to the wider adoption of blockchain, including financial investment and regulatory issues. The first book to focus solely on the potential of blockchain within the healthcare sector, it will appeal to international scholars, students and healthcare professionals interested in issues around patient confidentiality, data security and IT management.
