Blockchain is a sort of distributed ledger technology (DLT) that enables decentralized data storage and sharing. As medical information must be both secure to maintain privacy and bidirectional to permit the interchange of data for authorized uses, which may improve health outcomes, issues with storage of data occur regularly in the healthcare field.

At their most basic level, they allow a user community to record interactions in a common database such that, as long as the blockchain network is functioning normally, no transaction can be modified once it has been recorded. These traits imply that blockchain could provide a solution for certain data storage and sharing issues in the healthcare industry, but comprehending its future possibilities and real use cases is essential for effective adoption.

Ehrs And Big Data In Healthcare   

EHR interoperability and the interchange of big data in healthcare are two of the most widely discussed blockchain uses in the industry.

The Office of the National Coordinator launched the Blockchain Challenge in 2016, offering thousands of dollars in cash rewards to writers of white papers examining how blockchain technology may be used to solve the privacy, security, and scalability issues associated with electronic health records. A secure setting for clinical decision-making was a major theme throughout the applications, which helped determine the selection of fifteen winners.

Secure Clinical Decision-Making 

The effectiveness of care coordination and the capacity to link data to patients throughout the care continuum strongly influence clinical decision-making. The authors in one paper suggested that EHRs do not support healthcare records for lifetime.

Instead, they suggested MedRec, a blockchain-based solution that enables patients to approve updates to their EHRs, provide access to new physicians, and control provider sharing. The technique also has the potential to improve clinical decision-making by boosting patient confidence in the data available at the point of treatment, which may be a big problem.

Health Information Security 

Immutable Ledgers:

Blockchain technology may have a significant impact on healthcare data security. All health systems and organizations place a high importance on protecting patient data, but for providers, the growing amount of data and management-related concerns provide substantial challenges. Blockchain technology, which employs immutable ledgers that are continuously updated concurrently on all participating network nodes, might be useful in this situation.

Data Integrity:

Although offering several insecure gateways could potentially be a concern, blockchain is intended to reduce this risk. The data “blocks” in blockchains are linked to all the blocks that came before and after by distinct signatures, or “chains.” Instead of changing the old block when data inside a block has to be modified, a new block is introduced to indicate the modification. Each addition or modification of data is noted, along with timestamps.

Decentralized Consensus:

Blockchains also function utilizing decentralized consensus, which calls for unanimous agreement among all participants in the consortium using the blockchain on the procedures for validating and recording data.

Security against Malicious Actors:

For a malicious actor to try to take advantage of this and manipulate the data, they would need to take over the majority of the network’s nodes at once and change the whole blockchain pertaining to the data they are aiming for. Although not impossible, this is quite challenging because of the extensive network of nodes in the healthcare industry.

The Internet of Things and fog computing

Importance of PGHD in Healthcare IoT:

Patient-generated health data (PGHD) is crucial for gathering, analyzing, and using in the healthcare Internet of Things (IoT). IoT tools include glucose monitors, tell health kits, urine kits, etc. Although this data may improve clinical treatment greatly, it can also be inconsistent and poorly defined.

Challenges with Data Processing:

PGHD must be unambiguous, succinct, and almost immediate in order to be effective.

Role of Real-Time Analytics:

Real-time analytics are made possible by these features, and they may be used in urgent circumstances to save serious patient injury or death. Real-time analytics, which enable data to be transferred from the device to the cloud, have become more important to many organizations thanks to cloud computing. The analytics engine is then supplied the pertinent data, which is then processed and presented to the physicians.

Fog Computing:

Unfortunately, this approach may take some time, and in an emergency, it might be too much time. This issue has been addressed via fog computing. By placing a layer of computation between the device and the cloud, fog computing enables IoT devices to do analytics on their own. As a result, clinical decisions can be made more quickly and the cloud pipeline may be used for extensive analytics.

Sharing Health Data Across Organizations:

The capacity of fog computing to transform IoT devices into small data centers might also be used to share health data across organizations. Patient health data may be transferred across devices using a common interface and a fog computing system with preset user and authorization policies. However, the original hospital or doctor’s office is the only place where any data changes or edits take place.

Blockchain for Data Integrity:

Hospitals, payers, pharmacies, doctors, and other healthcare stakeholders would be able to access portions of the same EHR depending on permissions, rather than having to send a brand-new record each time one organization needed to make a modification. Blockchains distribute and update ledgers on each network node in a manner similar to this. Therefore, the security and data integrity standards of blockchain technology might be advantageous to the fog computing environment.

Enhanced Privacy and Security:

Users would be able to see and alter specific datasets via blockchain, and all devices would have simultaneous access to the most recent data. Blockchain prohibits unauthorized data tampering and is very difficult to hack due to the way it is structured, allaying privacy and security concerns common to various data-sharing schemes. It would be necessary to create blockchain-specific security and privacy procedures, but doing so might have a big benefit.
