Triassic Solution
Blockchain is a global technological progress in the field of data storage and distribution, especially in the financial field. The huge success in various industries also brings questions to the medical industry. People say that blockchain is the answer to interoperability. However, if chaos occurs, the blockchain will take twice as long to change medical services.
Start with the interpretation of blockchain, ask one question at a time, and then see what it means for medical services.
How does blockchain work?
Blockchain is a peer-to-peer decentralized accounting technology, which has three main components.
-
Distributed network: The distributed peer-to-peer architecture includes nodes representing network participants. Each node stores a copy of the blockchain and authorizes the authentication and authentication of digital transactions on the network.
-
Shared Account Book: Network digital transactions are recorded in the shared account book by members. Members run the algorithm and validate the transaction proposal, then add it to the shared ledger account after most members approve the proposal.
-
Transparent transaction: All digital assets or information stored in the blockchain can be used as transparent transactions. Each transaction is displayed as an encrypted hash, adding transactions in linear and chronological order.
Imagine the application of blockchain in the medical field
Important medical information is distributed in multiple systems and is sometimes unavailable when needed. The current medical infrastructure is labeled as insufficient to handle information exchange and needs to be adjusted. Gartner Hype Cycle’s latest data shows that the blockchain has exceeded the “trigger point of innovation” and reached the “highest inflation expectation” related to medical care and data integration.
Why does the blockchain need to be integrated into medical services?
The use of blockchain in the medical field is one of the main revolutionary factors, which is the lack of central managers. Why? The database is still tangible and therefore consists of bits and bytes. If the contents of the database are stored in the physical memory of a specific computer, it may be corrupted.
With blockchain, all data and transactions are protected by intelligent encryption technology without the need for a central administrator. The medical service handles confidential patient information and needs quick access to records, so the blockchain can safely share these medical records. Blockchain provides access security, scalability and data privacy.
Blockchain implementation in medical treatment will be a gradual process, rather than a panacea to solve all data management problems.
Five methods for blockchain to improve medical care:
- Patient records are continuously updated
Blockchain can help suppliers collect longitudinal patient records, including seizures, disease registration, laboratory results, and treatment, and promote the discovery of better nursing methods.
- Main patient index
The data managed by the healthcare organization may be inconsistent or duplicate. In addition, each EHR has a different field mode. Even the most basic data sets have different input and operation methods. The blockchain stores the entire database in a hash format, not just the primary key itself. User search address. You can have multiple addresses and thousands of keys, but you will return one patient.
- Confirm claim
The blockchain is operated by verifying the basic exchange, so the network can automatically verify the claim after agreeing to the contract execution method. In addition, since there is no central authority, there will be fewer errors and fraud.
- Logistics and Supply Chain Management
Blockchain based contracts can help healthcare organizations monitor the supply cycle throughout its life cycle. How the contract is executed, whether the contract is successful, and whether the contract delivery is delayed.
5) Interoperability
Reliable EHR interoperability and data storage procedures can be implemented through complex APIs. Combining with the blockchain network shared by authorized suppliers in a secure and standardized way will help eliminate the cost and burden of data account books.
In addition, the blockchain can also change revenue cycle management, drug supply management, clinical trials and fraud prevention.
Develop Internet products
Conclusion:
In the medical field, the potential of blockchain mainly depends on the willingness of medical organizations to develop the required technical infrastructure. Blockchain is an expensive technology. People worry that it will integrate with existing technologies. They will definitely guess their cultural adoption. But it is certain that blockchain has swept the medical industry in the past year, and has made a lot of investment in blockchain. Its broad potential is not surprising. Blockchain is expected to change the digital world in the future. One day you will do the same for big data.
