Blockchain in Healthcare Industry: A Game Changer

Get ready for a transparent healthcare industry.

Blockchain in healthcare

Blockchain has become a buzzword in the tech business and of course, for good reasons. Other than giving the basic establishment for creating a cryptocurrency area, it additionally has the ability to change how organizations work. It can be decentralized plans of action, make more productive procedures, and give a secure and dependable approach to trade information. 

While Blockchain has the potential to transform numerous ventures, it indicates extensive revolution inside the healthcare industry. Blockchain lessens the liability and efficiency concerns associated with the trading of medicinal information. The technology gives built-in levels of cryptographic security to conserve patient identity. 

Ultimately, patients may even access their own "information wallet," giving them control over their own healthcare information. This is indeed a controversial topic. On one hand, a few people in the healthcare business believe, just doctors should control that data to guarantee appropriate care. On the other, there's a developing number of individuals who need control of their own information. 

Due to its incredible features and enthusiasm, most of the organizations are ready to dive into the bandwagon. For example, Patientory is a self-depicted healthcare services cybersecurity startup. It was established in the aftermath of the WannaCry ransomware attack. This attack influenced approximately 300,000 machines in 150 nations. 

IBM Watson Health is additionally collaborating with the Food and Drug Administration. The objective is to utilize Blockchain to trade health-related information in a safe and productive way. Inevitably, IBM and the FDA intend to expand that into trading information between devices linked to the Internet of Things, cell phones, and wearables. Before, directly jumping to benefits of Blockchain in the healthcare industry. Let’s understand the working of Blockchain. 

How Blockchain Technology Works?

The Blockchain is a technology-based on a peer-to-peer distributed ledger. It has three key components as mentioned:

  • Distributed Network: The decentralized P2P structure has nodes comprising network participants. Here each member saves an indistinguishable copy of the Blockchain. This copy is approved to validate and confirm digital transactions for the network. 
  • Shared Ledger: The individuals in the system record continuous transactions into a common record. They run algorithms and confirm the proposed transaction. As soon as a majority of individuals approved the transaction,  it gets reflected in the shared ledger. 
  • Digital Transaction: Any data or a digital resource that could be saved in a Blockchain is a digital transaction. Every transaction is organized into a 'block,' and each block consists of a cryptographic hash. It helps to include the transactions in a straight and sequential request.

Why Do We Need Blockchain Technology in Healthcare?

There are multiple trends in the Blockchain technology that can be implemented in the healthcare industry. However, according to me, one of the biggest factors that make the utilization of Blockchain radical is the lack of a central administrator. Do you know why?

The database, even now, is a tangible thing. It consists of bits and bytes. In case the contents of the database are saved in the physical memory of a specific device, anyone who has access could easily corrupt or tampered with the data. In Blockchain, there is no requirement for a central administrator. It is eliminated or replaced by cryptography. 

Moreover, all the users have control over their entire information and transactions. As a matter of fact, healthcare handles confidential patient data and needs quick access to the information, Blockchain can streamline everything. It keeps medical records and enables their exchange in a secure manner. 

In short, Blockchain offers access to scalability, data privacy, and security. Its concept in healthcare is completely disruptive. However, it won’t be a remedy for data issues management. Instead, it would be a transformative journey where Blockchain technology is implemented step-by-step.

Use of Blockchain in Healthcare Sector 

Now, when you have a complete understanding of Blockchain and its core competencies, you might be curious in knowing its use in the healthcare industry. There are numerous uses of technology, but these are the key benefits of Blockchain in healthcare:

1. Longitudinal Patient Records 

Longitudinal patient records such as compiling episodes, lab results, disease registries, treatments, etc. can be accomplished via Blockchain. Therefore, whenever required, any record can be checked effortlessly without devoting much time to it.

2. Master Patient Index 

Frequently, while managing medicinal services information, records get mismatched or copied. Likewise, different EHRs have a unique schema for each field. With Blockchain, the whole informational collection is hashed to a ledger rather than only the primary key.

The client would search for the address. There can be several addresses and various keys, yet they will all yield to individual patient identification.

4. Claims Adjudication  

As Blockchain technology works on a  validation-based trade, the cases can be checked in an automatic manner where the network admits the way an agreement is executed. Additionally, since the network decentralized, there would be fewer blunders or cheats.

5. Supply Chain Management

The Blockchain-based contract can help healthcare organizations in regulating supply-demand cycles via their complete lifecycle. This technology can verify how the transaction taking place, whether there are any delays if the contracts are successful or not, etc.

6. Mobility

There is frequent pressure on the healthcare industry, in order to deliver quality. However, it should be cost-effective. With many Americans traveling across the world for medical care, some organizations want to leverage medical tourism to offset domestic healthcare costs.

Blockchain can help to enhance the interoperability in such cases. It takes the help of decentralized and standardized global health management records. No matter, what your geographic location is, Blockchain has the potential to facilitate mobility in the health sector around the world. It keeps the patient strongly in control of his/her medical data.


Inevitably, Blockchain is new to the industry. However, it has become a major point of discussion among numerous entrepreneurs. While there are different purposes of carefully gathering the healthcare data, it is considerably more critical to extricate the best advantages out of this healthcare data without confounding the procedures. 

For that reason the mobility of information and uniform similarity while working crosswise over various frameworks, is essential. Because of its sharp spotlight on streamlined flow, multi-faceted protection, and uniform portability, BlockChain innovation superbly handles differing present difficulties as said above. It helps in removing the most extreme yield from the information gathered on various levels.
