Will Blockchain Transform Healthcare?

“The Wall Street Journal recently noted that the United States “will soon spend close to 20% of its GDP” on healthcare. While it might not be possible to address the rising costs of healthcare in the immediate future, there are steps that can be taken to address issues of customer service and efficiency to improve the overall healthcare experience, while ensuring the protection of customer privacy. In recent months, there has been a flurry of excitement about the role that blockchain technology might play in the long-term transformation of U.S. healthcare.
I recently spoke with a few individuals who are deeply conversant in the challenges facing healthcare and how solutions like blockchain can be brought to bear. John Halamka is Chief Information Officer of Beth Israel Deaconess Medical Center in Boston, a Harvard University teaching hospital, a position that he has held since 1998. He also held the position of CIO for Harvard Medical School from 2001 through 2012. Halamka recently assumed responsibility as Editor-in-Chief of the new academic journal, Blockchain in Healthcare Today. In the inaugural issue, published in March of this year, Halamka proclaimed his manifesto, “As the Editor-in-Chief of Blockchain in Healthcare Today, my goal is to publish high-quality opinion pieces and research papers about use cases that really require blockchain”. Halamka continued, “Just using blockchain in healthcare because it’s cool does not make sense”.
Halamka knows of what he speaks. In his Journal call to action, Halamka goes on to note, “In 2017, I worked on several production blockchain applications, so I have a sense what works and what does not. Blockchain is not meant for storage of large data sets. Blockchain is not an analytics platform. Blockchain has very slow transactional performance. However, as a tamperproof public ledger, blockchain is ideal for proof of work. Blockchain is highly resilient”. I asked Halamka about what he sees as the greatest healthcare challenges where blockchain could make a difference. Noting that blockchain is ideal for ensuring data integrity where control is decentralized, Halamka cites three prominent opportunities:
- Medical Records. When a medical record is generated and signed, it can be written to the blockchain, which will provide absolute proof and confidence that a medical record cannot be changed. The integrity of the medical record is ensured. The same concept can be applied to clinical trials. This has impact in legal cases as well where the integrity of the medical record is pivotal.
- Consent management. In the current healthcare environment where every state has different privacy and consent regulations, blockchain could be used to record patient consent for purposes of data sharing. Any party seeking to exchange medical data about a patient could check the blockchain for permission to do so.
- Micropayments. The idea that patients might be incented is gaining traction. If a patient follows a care plan, keeps their appointments and stays healthy, there might be rewards offered through the blockchain. Similarly, patients might be rewarded for contributing their data to clinical trials and clinical research using the same approach.
