Blockchain in healthcare: transformative cases and emerging use cases

Blockchain technology has become an agent of change in the healthcare sector, resolving longstanding problems with patient-centered care, interoperability, and data security. This chapter investigates the different uses of blockchain in healthcare, presenting compelling and emerging use cases that highlight the revolutionary power of this decentralized and tamper-resistant technology. Initially, the importance of blockchain in securing patient data is discussed, with a focus on its ability to construct a tamper-proof ledger of health records, ensuring data integrity and improving patient privacy. Several real-world examples demonstrate the successful use of blockchain to protect sensitive information, restrict unwanted access and streamline data sharing among healthcare providers. Blockchain's decentralized architecture addresses interoperability, a longstanding challenge in healthcare. Smart contracts enable frictionless data transmission between heterogeneous systems, increasing collaboration and decreasing inefficiencies. Case studies demonstrate how blockchain has enabled secure and standardized data sharing, resulting in enhanced care coordination and patient outcomes. As the healthcare business digitizes and faces new difficulties, blockchain technology is proving to be a driver of positive change. This chapter emphasizes blockchain's varied influence in healthcare by giving compelling case studies that demonstrate its ability to disrupt the industrial landscape and redefine stakeholder relationships.
