Blockchain technology helps medical institutions to gain insights and increase the evaluation of medical documents. In this article we examined Blockchain technology as well as its major benefits for healthcare.
Definition
Blockchains are "an open-source database which keeps an ever-growing number of ordered records, also known as blocks." The blocks "are connected using cryptography. Each block has cryptographic hash of the block before it along with a timestamp as well as transaction information. Blockchains are a distributed, decentralized and open digital ledger utilized to record transactions across multiple computers, so that the records can't be modified retroactively, without altering the subsequent blocks, and without the consent of the network."
The Blockchain system operates on the internet using the basis of a P2P network of computers that all run the protocol and are running an identical replica of the ledger for transactions, permitting P2P value transactions that do not require an intermediary, based on machine consensus. There are many types of Blockchain technologies, such as hybrid, private, public or consortium. Each Blockchain network comes with its own advantages and disadvantages that fundamentally affect its use.
Blockchain in Healthcare Industry?
Blockchain is a distributed ledger that tracks transactions in a database that is made of blocks. Blocks are linked together using the hash number to create an intricate chain-like structure. Blockchain is a system with many advantages which make them an excellent option for healthcare facilities:
- Secure: Blockchain can be described as a safe block-based network. When a block is placed on the blockchain it requires consent from the majority of the other nodes of the network to modify the information within the block.
- Decentralized: Blockchain can be described as a distributed network in which nobody has to be dependable or be aware of anyone else on the network. Each member is able to access the exact same information as the other nodes of the network. If the ledger of a member has been altered, it will be rejected by the majority of member nodes within the network.
- Self-correction: When it is discovered that the information in one block within the network changes, other nodes of the network review their blocks and cross-reference them to determine the cause of the error.
- Distributed: Blockchain is a ledger distributed in which computers independently keep track, share and synchronize transactions in their own electronic ledgers.
Benefits of Blockchain in the Health Industry
- Securing Patient data: In the field of healthcare and protecting patient information is the most important aspect. In the event of a breach, patient records are compromised and can result in problems when trying to determine the problem or disease of the patient. This can be a problem for doctors and hospitals. Between 2009 and 2017, 176+ million records of patients were compromised. The hackers accessed the bank and credit card information and used it to commit crimes. Blockchain is tamperproof, distributed, and unbreakable technology that aids to access patient information more easily and secure manner.
- Medical Drugs Supply Chain Management: Medicines or drugs aren't produced in hospitals. They are produced in laboratories and pharmaceutical companies across the globe. The drugs are then distributed throughout the world depending on the needs of each country. What happens if someone alters the drug while transporting it across the nation? Therefore, the medical supply chain needs to be secure and transparent for both exporters and importers. Blockchain can solve this issue because it has characteristics like transparency, decentralization, as well as the ability to tamper-proof. Once a distributed ledger has been developed for the drug each transportation point will be logged into the blockchain from the point of origin until the point of destination, thus making it transparent throughout the entire transportation.
- Tracking of Drugs: Blockchain can be the most trustworthy, reliable, and secure method to trace every drug back to its origins. Every block of data that includes details about drugs will have a hash value that is linked to a different block of data. This is to ensure that the information hasn't been altered. The transactions that are made in the blockchain are available to all parties authorized. The purchasers of medicines can verify the authenticity of bought products through scanning the QR codes and then looking for all the relevant information such as the details of the manufacturer as well as other details.
- Enhances healthcare records: Using electronic technology electronic health record systems store health information in digital format, which is generated and stored by a variety of healthcare institutions. Blockchain solves issues like accessibility, interoperability and authenticating health information by linking health records with physical ones and sharing the ownership of these records with all parties.
- Optimization of the supply chain: Primary challenge in the health sector is to guarantee that the authenticity of the source of medical products to guarantee the authenticity of the medicines. Through blockchain technology, with the help the blockchain tech, food items can be tracked from the point of manufacture through each step in the chain of supply. This allows for complete visibility and complete transparency of items to buy. This could help companies apply AI and anticipate demand better and improve the supply in line with demand while at the same time it will increase the trust of customers.
- Cryptocurrency Payments: Blockchain lets you receive medical assistance and to pay for the services you receive in cryptocurrency. For instance, Aveon Health and Micropayment are the two technologies built on Blockchain and makes use of the benefits from Blockchain technology.
- Decentralized storage of medical records: An interplanetary system of file storage (IPFS) allows the storage of files with a version number in storage environments that are decentralized. The filesystem creates a unique hash known as the base configuration IED description that ensures every version of the files are the same. The hash generated by IPFS lets users browse websites for data however, blockchain files cannot be changed, websites change frequently, DNS must be updated after every update. Therefore, IPFS resolves this issue by mapping website addresses to DNS. Health makes use of the benefits that come with Bitcoin cryptocurrency. The micropayment system will document each detail of the patient's activity that relate to the examination for treatment.
Detriment of Blockchain in Health Industry
- Blockchain development cost: The cost of creating, maintaining, and updating the healthcare Blockchain is not known There are many US web development firms and US customized software firms who charge their own fees. It isn't yet clear what the current industry standard is. Cost is the main element in the choice to adopt blockchain technology within the health sector.
- Blockchain cannot go backward Data is unchangeable: The immutability of data has always been among Blockchain's major disadvantages. It is obvious that many applications benefit from this, such as the supply chain and financial systems, among others. If you take examine how networks function it is essential to recognize that this immutability will only be realized only if the nodes within the network are equally distributed. This means that the Blockchain network is managed by an entity that is the owner of more than 50% of all the devices, making it vulnerable.
- Expertise: The process of implementing and managing the implementation and management of a Blockchain project is a challenge and, as such requires a thorough understanding of the company to successfully complete the process. There is a requirement to recruit many experts in the area of Blockchain which can be a hassle that is considered to be one of the major disadvantages of Blockchain. In Addition, it is necessary to educate existing professionals on how to utilize Blockchain and ensure that the team managing the business can comprehend the complexity and outcomes of a blockchain-powered company.
- Data Breach: As it is possible to access patient records from a trusted source, there could be a major breach of data privacy. Healthcare is a sensitive field with a code of conduct enforced by strict laws related to the confidentiality of data, this may create a risk for regulatory compliance and outweigh the drawbacks of having access to data in the event of an emergency.
- Absence of Governance: Managing the entire data record isn't an easy job, since healthcare is a prevalent issue all over the world and no one has the power to exercise control over it due to its non-centralized nature. Therefore, companies face opposition when they try to convince individuals to handle a particular responsibility in blockchain technology to their benefit. So, concerns over the use of blockchain technology in healthcare are unsolved.
- Self-centered Players: Many organizations are reluctant to divulge their ownership of information because they fear that their profits will be diminished. Healthcare insurance companies and hospitals are a few examples. The inability to disperse data at their ends gives them an advantage in competition and, consequently an impression of unity is not present. This can lead to the detriment of some useful inventions.
