Global healthcare data sharing suffers from lack of security, clear possession, interoperability and accessibility. Can blockchain provide solutions?
Healthcare data sharing and the worldwide info infrastructure are long overdue for an overhaul. There is a lot to be stated about rising healthcare costs, inefficiencies and events such as the Covid-19 pandemic response, but there is little to be stated about the techniques underpinning this massive US$10 trillion industry. Even more important than our rising drug prices is medical malpractice.
Medical errors have become the third leading cause of death in America. Many of those errors will be traced again to gaps within the affected person file that lead to improper treatment.
Three main points plague the industry on the health data side. First, focusing on this data is very worthwhile for hackers. Ransomware and cloud storage exploits are among the rising number of strategies used, and though funding for cybersecurity is rising among institutions around the world, hackers have managed to maintain up the tempo. Thousands and thousands of affected person records have been exposed over the years and a few cyberattacks are placing lives at risk.
Present healthcare data systems are impartial of one another. The quantity of data created every day continues to increase exponentially, but it’s created inside isolated techniques.
As a patient attempting to access your personal healthcare data for personal use or via a healthcare skilled, it may be unattainable to trace down your private historical past. In case your knowledge is created in a pharmacy, a lab or even an app, it’s inaccessible from different platforms. This is inefficient and will be bad for the patient’s health.
Healthcare suppliers are unable to access a detailed set of information with which to diagnose and treat the patient.
To add here, sufferers haven’t any control over their own data. The techniques and establishments that created their data additionally personal that knowledge or at the very least deal with it as their own.
Not only does this leave it susceptible to the cyber assaults talked about earlier than, but it surely makes it troublesome for sufferers to search out it when wanted. Their health data turn into dependent on those establishments, therefore their management over their own well-being turns into linked to large, for-profit, centralized entities.
Nationwide, government initiatives
The Workplace of the Nationwide Coordinator for Health Info Expertise Nationwide Interoperability Roadmap describes the steps wanted to be taken for health knowledge sharing to grow to be extra moral and environment friendly.
- Step One: Establish data sharing standards and analysis strategies for implementation.
- Step Two: Construct and increase these strategies to start creating an interoperable system nationwide with the intent to reduce costs and enhance constructive health outcomes.
- Step Three: After achieving nationwide interoperability and quick/efficient entry to data, place the person sufferers within the heart of the health data sharing course and assist them to learn how to interact with it.
Congress said that it was “a nationwide goal to achieve widespread trade of health info via interoperable licensed EHR know-how nationwide by December 31, 2018.”
This comes from the Medicare Entry and CHIP Reauthorization Act of 2015. As a result of America spends practically 20% of its GDP on healthcare, the government realizes the essential want for cohesion and cooperation between institutions. The electronic health record (EHR) techniques mentioned within the quote above have seen widespread adoption, however nothing close to what is important for a smoothly functioning system.
Many hospitals are starting to make use of third-party data-sharing providers that conform to EHR standards, but a lot of that data switch is one-sided. Information is shipped or obtained as needed, and information should not be properly up to date. And naturally, organizations outdoors of those networks don’t profit from this admittedly limited ecosystem.
How blockchain technology may help
The blockchain excels at fixing each of the three principal issues in health data sharing: security, interoperability and accessibility.
Interoperability
Info will be accessed via the blockchain by anybody on the earth without permission. This gives the chance to provide people ownership of their very own health records. Every patient can manage and preserve their own patient file, the place amendments can only be made by verified healthcare suppliers.
When presenting these records to their healthcare supplier, the supplier can confirm previous entries and modifications with the blockchain to make sure that the affected person is telling the reality about their situation.
By interacting with only one supply of data, medical doctors and sufferers can preserve an up-to-date file that may be accessed and up to date by anybody else at any time as long as they have the patient’s approval. No small detail will go unrecorded or unnoticed so long as the healthcare skilled makes use of the provided system.
Every change to the file is recorded on the blockchain as a new transaction. These transactions will be traced and verified for long-term integrity.
Accessibility
Ancillary institutions such as pharmacies and insurance companies also can access the verified, secure medical records immediately, saving time and energy spent finding and waiting for permission from whoever might have the wanted information on the time. Entry is as simple as offering consent.
This also creates a possibility for analysis services to have easy access to a large, comprehensive database of data where consent from the patient can be given at the click of a button. Sufferers may even be incentivized to make use of the blockchain-based platform and share their info with these sorts of services with small financial payouts enabled via sensible contracts.
Smart contracts are bits of code that can be interacted with to execute predefined features reminiscent of releasing quite a lot of funds when certain conditions are met.
Security
Coming back around to security, it is very important to note that not all the patient’s information can be saved immediately on the blockchain.
The blockchain stores a really small quantity of transaction info. The majority of the knowledge would nonetheless be saved on centralized servers until decentralized storage was implemented. Whereas this doesn’t pose a menace to the previously talked about utilities, it does need to be expanded on.
The good thing about the blockchain as security is that it’s virtually impossible to hack. Information stored on the blockchain is very secure. Transaction details and authenticity verification is immutable.
The info stored on the centralized servers wouldn’t have this same immutability. However, as long as the data saved on these servers may only be accessed via the blockchain’s cryptographic algorithms, the data can be far safer than easy access through admin passwords and human error.
The government and the healthcare industry as a whole perceive the need for a complete data-sharing ecosystem with built-in interoperability and security. Blockchain technology, when utilized accurately and optimized over the course of years, is the perfect answer available for each institution and people.
