Does Blockchain Tech Have a Future in Well being Care?

By Stephen P. Williams

Proponents of blockchain expertise say we’re on the cusp of a revolution in well being care. They envision a future the place medical doctors and establishments share medical data simply, and sufferers management their private information slightly than letting tech corporations harvest our information without spending a dime and promote it for revenue. If the idea of Web3 — a blockchain and cryptocurrency-based web that grows to naturally displace our present World Broad Net — proves out, it may make their visions actuality.

However others within the well being care trade, even when they see the necessity for a revolution, worry that blockchain at the moment has too many blindspots to be efficient. “In my view, though I feel the influence of blockchain expertise can be big within the well being care system sooner or later, a profitable and scaling resolution is prone to be years forward of us,” says Lukas S. Vogel, MD and blockchain skilled in Baden-Baden, Germany.

What Is a Blockchain?

Blockchain got here into the favored consciousness when it served as the inspiration for Bitcoin, the cryptocurrency that was invented in 2008. Ever since, the expertise has been misunderstood, each by the cult-like fanatics who consider it’s the cure-all for each drawback the world faces, and the narrow-minded cranks who say it serves solely to assist pyramid schemes, gangsters, and tyrants.

Let’s go away these fanatics and cranks to their Twitter wars, and strategy blockchain and well being care from the center floor. First, a blockchain primer:

Blockchain is software program, it’s so simple as that. This software program is a digital model of the previous inexperienced account books your grandparents may need used to trace cents spent and cents earned. Besides that as a substitute of simply two columns — debit and credit score — blockchains (there are numerous blockchains, with many extra to return) have three: debit, credit score, and verification. This triple entry accounting system requires no auditors, verifiers, or gatekeepers. As a result of each transaction is public and immutable, nobody can change the information with out triggering alarms all through the system. As soon as a transaction is registered on a blockchain, that truth stays there endlessly. It’s related to a particular blockchain handle, however these addresses can stay nameless.The precise information — corresponding to written paperwork, movies, or check outcomes — are saved “off chain,” in information banks, as a result of blockchains are designed to file possession, slightly than retailer information.

Nobody owns these public blockchains; one innovation is that they’re managed by members within the chain. Non-public, or enterprise, blockchains are owned by consortiums or corporations, corresponding to IBM, and they’re extra centralized.

To make use of private and non-private blockchains creatively, corporations construct apps (referred to as dApps in blockchain lingo). The dApps usually monitor possession of digital property, corresponding to cryptocurrency tokens or well being data.


Well being Care Corporations’ Curiosity in Blockchain

In the meanwhile, quite a lot of well being care corporations, together with IBM, SAP, Facilities for Illness Management and Prevention, Patientory, and Nebula Genomics are utilizing enterprise blockchains for centered duties corresponding to:

  • Verification of credentials
  • Sharing medical data
  • Monitoring prices and funds
  • Monitoring organs and transplants
  • Following the pharmaceutical provide chain

In line with some trade consultants, it’s potential (although not assured) that some very helpful purposes will turn into extensively used within the subsequent 5 years. There’s an enormous push to provide sufferers and medical doctors sovereign ID’s, in order that they’ll management their id, popularity, data, and different information. Proper now, we medical customers give our information away.

“Now, the data are owned by the hospital or different company, which might promote the information — you continue to need to ask for permission to entry your individual information,” says Jose Morey, the North Carolina-based chief medical officer for a medical expertise firm.

Giving sufferers management over their very own information received’t be a simple process. Even placing apart technical points, it will require an enormous quantity of cooperation between corporations that don’t have a lot of an incentive to cooperate. “It’s very arduous to resolve the well being care issues,” says John Bass, founder and CEO of Hash Well being, a Nashville-based enterprise studio that’s constructing new digital well being startups. “That takes enterprises which might be prepared to work collectively. It takes new administration methods. It takes methods change.”


The Challenges of Blockchain for Well being Care

Widespread adoption for this expertise received’t be simple, and it would even be dangerous. Listed here are a very powerful potential drawbacks:


A cryptocurrency is a digital coin, corresponding to Bitcoin, that’s tracked and licensed by a blockchain. There aren’t any precise bodily cash. Somewhat, the digital cash are saved, as traces of code, in digital wallets that may solely be unlocked in your pc or system with a non-public digital key. Bitcoin and ether are the 2 most used cryptocurrencies. The value of every is very risky, rising or dropping in worth by hundreds of % in a yr.

Many enterprise innovators, together with in well being care, consider that crypto cash could possibly be used to incentivize behaviors — in well being care, maybe, you’d obtain the hospital’s branded cryptocurrency in the event you confirmed that you just exercised thrice every week, as your physician instructed. This idea is just not far-fetched or technically tough, although no hospitals are but utilizing it.

“There are regulatory questions across the regular crypto stuff, exterior of well being care. The cash that might be utilized in well being care are much more complicated with out having to fret about that,” Bass says.

Web3 believers wish to incentivize sufferers to be wholesome, share their data, and do different issues by paying them with cryptocurrency. However there’s a great likelihood that speculators would enter that ecosystem and probably manipulate the worth of the cash. Plus, the IRS and the SEC haven’t but settled on particular guidelines about cash, tokens, and NFTs. There’s a actual threat that new rules will severely hamper corporations’ capability to make use of these incentives.


Nonfungible tokens, or NFTs, are just like crypto cash, besides that every NFT is certainly one of a sort. To date, NFTs have been used as artwork objects: you purchase a token that claims you personal an image, and the funding can admire identical to an precise image (Besides you possibly can’t dangle it in your own home).

However the tokens can serve nicely to register everlasting data of your id, medical data, and different well being care information. The data is sharable, as you would like. You might personal the NFT that has your whole train information, as an example, and use it to share related info together with your bodily therapist, or promote your information to a analysis firm. The largest drawback now could be that buying and storing NFTs requires some technical expertise, and the consumer expertise proper now could be too cumbersome to onboard lots of people.


Blockchains are practically unattainable to hack. The Bitcoin blockchain has by no means been hacked, and the Ethereum chain was solely hacked as soon as, quickly after its inception. Given its present dimension, it is extraordinarily unlikely that it may occur once more. Nonetheless, the dApps constructed on high of blockchains to handle information, IP, ID, and different capabilities are generally weak to stylish hacking. And when, if ever, quantum computing turns into widespread, that expertise can be highly effective sufficient to crack the cryptologic codes on blockchains.

Till that point, customers are fairly prone to hackers operating phishing schemes. Whereas blockchains themselves can’t be hacked, individuals will be tricked into surrendering the key phrase that provides them entry to their non-public wallets. Sharing these phrases is like sharing the code to your safe vault. As soon as somebody has that, they’ll steal any cash or NFTs in your digital pockets, and in addition steal your well being data and different information. Given the character of the expertise, the thefts can be registered immutably on the blockchain. However since blockchains are amoral, the blockchain would not do something about it.

Distributed Autonomous Organizations (DAOs)

DAOs are teams of individuals organized on the blockchain who use cryptocurrency as a funding mechanism, and make most massive selections by voting. They don’t have any central chief or authority. These organizations with minimal hierarchy have solely been round for a decade or so, however not too long ago DAO’s have exploded in reputation amongst startups in all sectors. Some well being care innovators now are focused on funding their ventures with DAOs, or organizing sufferers with uncommon ailments to boost funds to analysis medicines for his or her illness. That is essential as a result of many much less widespread therapies and diseases usually are not of curiosity to enterprise capitalists and others who need big returns from big merchandise. But most everyone seems to be ready till DAOs are much less dangerous, and simpler to clarify to stakeholders. Nobody has actually nailed the consumer expertise of DAO’s but. They’re like Nineteen Seventies communes, however with numerous cash and a deal with enterprise. They impart by means of chat rooms in an internet platform referred to as Discord.

“The Discord servers are pure chaos,” Bass says. “Asking a well being care supplier to hitch Discord can be form of a joke.”

Cross Chain Portability

Whereas there are dApps that assist transmit information from one chain to a different, the extent of interoperability between chains that might be crucial for remodeling the American well being system merely doesn’t but exist. For instance, it’s essential {that a} hospital that makes use of one chain have the ability to share information with a health care provider who makes use of one other. In the meanwhile, that’s generally tough. The well being care system is not going to be unified till that is extra potential.


Blockchain appears to supply the proper resolution to a credentialing, which is a standard well being care drawback. Each doctor has a relationship with 4 or 5 well being methods and payers. Every of these companies should certify that the doctor is who she says she is. This course of now could be largely analog and may take months, and needs to be reconfirmed each 2 years. No hospital shares this information, so every hospital has to do it for themselves. This can be a good use case for the efficiencies of blockchain, and a few corporations are engaged on it. Within the meantime, corporations pay tens of millions of {dollars} for extra conventional certification companies yearly.

A great way to retailer a health care provider’s credentials can be on NFTs saved in digital wallets. However that is likely to be too technologically difficult for at the moment’s medical doctors due to the technical savvy required.

“When you created a self sovereign pockets for a doctor proper now they would not know what to do with it,” Bass says.

The Surroundings

Many educated individuals are involved concerning the quantity of vitality the computer systems of two of the biggest chains, Bitcoin and Ethereum, use to confirm and safe “blocks” of information on the chain. That is at the moment a really actual difficulty. Nonetheless, Bitcoin members are more and more switching to utilizing renewable vitality, as a result of it is cheaper and sustainable. And Ethereum is anticipated to start out utilizing a distinct blockchain expertise, referred to as proof of stake, this yr, which can scale back its electrical energy utilization by greater than 90%. There are a selection of different chains, each private and non-private, that already use this low vitality methodology of certifying information.

It appears sure that blockchain goes to have an effect on well being care. The expertise may even result in a revolution in well being care, the place information is non-public and expenses are billed transparently. The place organ transplants run easily and equitably, and fee friction is lowered. It’s all potential, however the expertise positively has to leap some hurdles earlier than it might occur for actual.
