In BriefThe Centers for Disease Control and Prevention (CDC) is investigating how they might use the blockchain to share medical data between organizations across the United States. This could have a profound effect on the CDC's ability to respond to epidemics.
Blockchain technology is already revolutionizing the world of finance, and it’s set to do the same for various other industries, too. One of those industries is healthcare, and now, the Centers for Disease Control and Prevention (CDC) is looking into ways to utilize the technology.
The CDC helps maintain public health in the U.S. by sharing information about infectious diseases with state and local health departments. However, carrying out that task in a timely and efficient manner is rather difficult.
The sensitivity of health information plays a huge factor in this difficulty. The CDC needs to make sure only medical professionals with the proper credentials have access to the data. Even tighter constraints are in place with regards to editing it.
To ensure these privacy standards are met, various processes must be carried out, and some of these processes have to be performed manually. This takes time, which might be at a premium when an epidemic takes hold. The blockchain has the potential to make this process much more efficient.
The CDC currently provides medical professionals with an app they can use to log information pertaining to their patients. However, personally identifiable information can’t be stored in the cloud for security reasons, and the alternative storage solution slows down the whole process.
Jim Nasr, chief software architect at the CDC’s Center for Surveillance, Epidemiology, and Laboratory Services, told the MIT Technology Review that this wouldn’t be the case with the blockchain. The tech would allow the same data to be stored and shared far more rapidly, while still complying with laws pertaining to user privacy and security. “Public health and blockchain really do belong together,” said Nasr.
This concept is still in its early stages, and many big questions have yet to be answered. Should local, state, or national bodies be in charge of the data? Who should be able to access it? How should patients and public health organizations be identified in the database?
Once these issues are sorted out, the CDC can move forward with blockchain implementation. Nasr and his team are currently working on several different prototypes, and they hope to start building actual applications for the technology in 2018.
