Interoperability in healthcare industry has been traditionally focused around data exchange between business entities, for instance like various hospital systems. However, there has been a recent rush towards patient-driven interoperability, in which healthcare data exchange is patient-mediated as well as patient-driven. Patient centered interoperability, it brings new challenges around security, privacy, technology, and governance that must be addressed for these types of data sharing to succeed at scale. This paper looks at how block chain technology might facilitate the transition through five mechanisms which are: (1) digital access rules, (2) data aggregation, (3) data liquidity, (4) patient identity, and (5) data immutability.  blockchain-based solution that facilitates a scalable and secured inter-healthcare Electronic Health Records exchange. These healthcare providers maintain their records on separate blockchain networks and are independent of each other. We then look at other obstacle to blockchain-enabled patient-driven interoperability, specifically clinical data transaction volume, privacy, patient engagement, security, and incentives. It concludes by noticing that while patient driving interoperability is an growing trend in current healthcare, given these challenges, it remains to be whether blockchain can able to make the transition easy from institution-centric to patient-centric data sharing. Privacy and confidentiality of the medical data are in high concerned to the patients and authorized persons to use this data. On the other hand, scalability and interoperability also play an role of importance in problems that are considered.
