Blockchain technology enables healthcare data management and accessibility

Blockchain can be described as an immutable ledger, logging data entries in a decentralized manner. It has been argued that this emerging technology disrupts a wide variety of data-driven domains, including the health domain. In terms of data integrity, immutability, audit, data provenance, flexible access, confidence, privacy, and security, today's healthcare data management systems face critical challenges. A significant proportion of current healthcare networks leveraged for data management are often clustered, raising possible risks of single point collapse in the event of natural disasters. Blockchain is a decentralized, evolving, and revolutionary platform that has the ability to radically revolutionize, reshape and change the way of data accessibility in the healthcare sector. This chapter explores how the use of blockchain for data processing systems and accessibility in healthcare will stimulate advances and deliver substantial changes. This chapter presents a case study to show the practicality of blockchain technology for various healthcare applications.
