The blockchain is an idea centered around the concept of a secure, digital ledger system that provides a system for efficient, auditable transactions of almost any type between entities. All information related to blockchain transactions is at once both independently verifiable by all (even outside) parties as correct and also inscrutable to entities without explicit permission. The first and probably most well-known implementation of blockchain technology is Bitcoin [1].

Potential Use Cases in Healthcare

Though there has yet to be a breakthrough report or use-case for blockchain technology in healthcare, there are many potential ways that the blockchain could be implemented within the current healthcare structure. Any list will likely be incomplete, but these examples represent some of the published and available literature on blockchain implementations in health.

  • Health Information Exchange (HIE) - One major area that blockchains may be able to facilitate is the secure access to and communication of patient health records between individuals and institutions. There have been multiple white papers published on the topic, including groups from the Mayo Clinic [2] and MIT [3] who described a system for patient information exchange based on blockchain technology that would allow patient-controlled access to records across institutions using HL7 Fast Healthcare Interoperability Resources (FHIR), JSON, or other encoding system. In these models the actual health care data are not encoded in the blockchain, but are merely references pointing to where the data reside, such as at institutions or in a "data lake" [4]. Similarly, a group out of China described an app called Healthcare Data Gateway (HGD) that allows patients to view and directly control rule-based access to their health records with a smart phone interface and authentication provided by a blockchain network. [5] These ideas support the concept of patient-owned medical data, and would have the effect of decentralization of medical records in ways that are as yet undetermined.
  • Health Research Integrity - [6]
  • Personal Health Records - This concept dovetails with the idea of HIE using the blockchain, but focuses more on the secure maintenance of a personal health record (PHR) by patients. No production PHR has been released based on this technology, but concepts such as MedVault [7] use alternative blockchains such as Colu to store patient data directly on the blockchain. Patients could then share or authorize doctors and other health entities to access and modify their data.

Other Blockchain Use Cases

Cryptocurrency

Bitcoin (BTC) was the first cryptocurrency based on the blockchain, and was developed by someone calling himself Satoshi Nakamoto. The protocol was introduced in 2008 after the publication of a white paper describing the algorithm and the mechanisms for generation and distribution of BTC.

Smart Contracts

Securities Exchanges
