This domino effect allows all users within the blockchain to know if a previous block's data has been tampered with, making it difficult to alter or destroy without proper protocols. In addition, everyone with access to the blockchain can see when and who had triggered this change, making it nearly impossible to modify or destroy these records. Continuously evolving technology, just like change, is a constant in healthcare.
Health data is one of the most sought after in the information economy today. In fact, big data is considered the "gold rush" of the 21st century. Blockchain allows for patient information to be accessed in real-time through hubs that connect all stakeholders to the evolvement of a patient encounter. The data is shared across various parties, including providers, payers, and patients. In addition, each party can add to the ledger, which enables real-time access and the exchange of information.
Currently, hospitals are like islands without bridges connecting them to each other or other entities within their own care continuum, such as labs and private practices. Instead, each island maintains its own database - a siloed system whose structure makes it difficult for one hospital to communicate with another, even though they may be part of the same network.
