Need For Blockchain In Healthcare Industry 

Everyone was overwhelmed by healthcare headlines throughout 2020 and 2021, especially since COVID-19 claimed the lives of millions of people amidst the shady-looking statistics that every nation’s administration desired to represent. While medical infrastructure dominated healthcare news, the need of maintaining authentic information infrastructure in the healthcare ecosystem received less attention.

The current healthcare information architecture is highly fragmented, with crucial data dispersed across various systems and inaccessible to the majority of people. Falsifying reports and withholding essential information from patients are examples of medical fraud. Since the current database is stored in a physical system, anyone with access to it can modify the information as needed.

In addition, a healthcare provider’s ability to give optimal health results to patients in real-time is hampered by this inconsistent and false set of data.

Blockchain technology, serving as the foundation for a worldwide electronic health record, provides natural solutions to these issues. It provides a secure digital environment capable of storing and authenticating patient information as well as providing public access to all healthcare information.

Simply put, with the central authority removed, all users will have complete power over all transactions and information. In essence, Blockchain will provide the healthcare business with security, scalability, and data privacy.

Blockchain’s applicability in healthcare is extremely disruptive. This revolutionary journey would be implemented in a step-by-step manner, as it was in Estonia previously. To begin, Estonia successfully implemented blockchain technology in 2012 to secure health data. Subsequently, in 2021, over 95% of the country’s healthcare information is ledger-based.

If Estonia can, so can other countries and that brings us to an important question – 

What are the Possible Applications of Blockchain in Healthcare? 

  • Data Security 

The blockchain’s protected network provides an edge over the old approach in terms of securing health information. Data can’t be modified or erased after it’s been added to the blockchain. Even if the data needs to be updated, a new record is created that includes all prior entries.

Furthermore, each record is accessible through a unique private key that is controlled by the patient. Since each document is represented by a hash, verifying the modifications to the original hash ensures the highest level of transparency and verifiability.

  • Health Insurance Claims 

Another area where Blockchain is uniquely adapted is the sphere of health insurance claims. When its data is seamlessly connected with the Blockchain network, processing times will be accelerated, fraud risks will be reduced, and time and money will be saved. This further allows insurance claims to be processed in real-time. 

  • Supply Chain 

From real-time tracking of medical supplies from manufacturers to minimizing the danger of human mistakes in remitting transactions, Blockchain’s integration with an organization’s supply chain can lead to improved productivity and quality control. It can also be used to figure out how much labor costs and how much carbon emissions are generated by supply chain functions. Organ transplant is another use case of a Blockchain-based supply chain in healthcare that is becoming extremely popular.

  • Medical Research 

Aside from the obvious advantages, the usage of electronic health records might be expanded to industry research. Medical research can only be deemed to be successful if the data is of high quality and readily available.

The ownership rights granted to patients in Blockchain can be used for research purposes, but only if the information is subject to adequate consent. It would enable research institutions to compile a slew of open data in order to advance clinical research and public health reporting.

To sum up, blockchain qualities like decentralization, data provenance, reliability, and smart contract support are ideal for the advancement of modern healthcare systems. Hyperledger Fabric healthcare system takes it one step further by introducing modularity to the ecosystem. 

While the first generation of blockchain frameworks, such as Bitcoin, was designed primarily to facilitate cryptocurrency transactions, more recent blockchain-based applications have made themselves available for healthcare uses as well.

Different blockchain frameworks, as well as the technical requirements of the healthcare business, should be considered while developing Hyperledger healthcare applications.

The privacy of patients and their data, for example, is one of the most significant requirements in the creation of Hyperledger healthcare applications. While standard blockchain frameworks demand complete transparency, the European General Data Protection Regulation (GDPR) governs public access to such information.

Furthermore, the scalability of transactions is another crucial necessity of the healthcare industry that must be met by an ideal blockchain infrastructure. Transaction validations and consensus protocols are critical in determining transaction scalability in healthcare applications.

Various Blockchain platforms to Develop Healthcare Applications 

  • Bitcoin 

Working on a PoW consensus, Bitcoin is a permissionless blockchain network where there are no restrictions on anyone starting mining to create a block. Each user, also represented as nodes, holds a copy of the identified ledger. Therefore, making it possible for every user to oversee every transaction. 

This type of public blockchain network is not suitable for healthcare applications since it is vulnerable to privacy and security breaches. Furthermore, the time it takes to reach a consensus can have an effect on the platform’s ability to scale transactions.

Another key feature that Bitcoin lacks is the facility to execute smart contracts, without which, dreaming about healthcare application is near to impossible. 

Apart from that, how bitcoin comes into the picture for the healthcare system is by providing a seamless, transparent, and instant financial service.

  • Ethereum 

Although Ethereum solves the major problem of supporting the execution of smart contracts, this public blockchain network still lacks behind on a few important considerations required to develop efficient healthcare applications. 

Ethereum smart contracts are often written in Solidity Programming, an Ethereum-specific programming language that requires a developer to understand in order to construct the application. Furthermore, its consensus process has a high transaction cost, as well as a higher risk of security vulnerability and scalability.

Apart from these, platforms like Corda, Quorum, Hedera, and EOS are also being used in one way or the other for creating a Blockchain-powered healthcare system but Hyperledger fabric healthcare stands as the best option.
