How can Blockchain be Used in Healthcare?

Healthcare is one of the fastest-growing and innovative industries where investment is mounting. The biggest challenge, however, is to cut down on organizational costs and eliminate inaccurate records as well as inefficient data management practices. This is where Blockchain technology seems to promise a comprehensive solution. Blockchain as a data encryption technology could be an effective solution to the digital transformation of everyday battles involved in healthcare today. Let’s first understand blockchain before learning how it can be used in healthcare.

What is Blockchain?

Basically, blockchain is a technology that comprises blocks and a chain. It is a data encryption system where a shared record of transactions is seen as a chain with each transaction appearing as one block. Here blocks of record are kept together by means of cryptographic keys or signatures which are stored in shared digital ledgers.

Here are a few known applications and use cases of blockchain in the healthcare industry:


High-quality and Affordable Patient Care

As blockchain enables a single decentralized system for storing health records, it becomes feasible to deliver good quality patient care with affordable standards. Also, each record of the transaction remains in its most updated form and is constantly synchronized which further ensures uncompromised security. Using safe authentication technique, blockchain application for healthcare makes way for secure and faster retrieval of data only by those who are authorized to access it.


Flawless Communication

The presence of blockchain technology for data encryption also equally means avoiding any chance of miscommunication that might happen among working professionals or between doctors and patients involved in the common healthcare system. Patient health and insurance data are shared and stored via blocks of transactions, which means it offers a single common layer of transactions where only authorized people can send and share data securely. Due to smart authorization protocols and controlled data sharing, any communication errors can be prevented and seamless connectivity can be established.


Electronic Health Records for Fruitful Research

The present healthcare system has electronic health records that make sure the medical information of a given patient is automatically updated and shared with a specific organization or a network of organizations. However, this system of medical information sharing can be further extended so that the chosen set of information present at the top layer of the chain can be conveniently accessed for the purpose of future medical research and innovations. This is possible if the information under process is not classified as the most personally identifiable.

This allows healthcare professionals and clinics to utilize a broad spectrum of medical data left by thousands of patients. It results in efficient research, worst-case identification, and public health improvement.


Collaborative and Interoperable Patient Care

Efficient and accurate Patient care is central to any healthcare solution. Blockchain does it well by allowing individual patients to share the available health information on the chain with other health providers. This is seamlessly performed through a shareable private key. The approach helps different users make the patient care process collaborative and interoperable.


Reliable Standard of Data Security

Data breaches are a soaring concern in the healthcare industry where healthcare record security is crucial. Blockchain enables a single layer of transactions in terms of blocks, the kind of data security that helps shield health information from getting breached. Its private key feature provided to each individual across the shared system can be unlocked strictly by an authorized individual, and that too, for a limited period.
Due to unbreakable information security, hackers need more efforts to breach well-synchronized transactions and fetch the health information of people involved.


Faster and Better Diagnosis

In blockchain technology, one secure system stores specific standardized data on the chain with private keys. Authorized professionals and patients share private links to previously stored health information. The process in turn enables organizations to make precise diagnoses and interventions. Since blockchain service is available to each individual using the technology, it becomes possible to deliver personalized care to each patient.


Health Insurance Claims

The blockchain enables honest claims and a transparent system of presenting the medical events as they happened. It gives rest to frauds and hackers by ensuring immutable encrypted data at any stage of transactions. With its secure non-traditional data environment, insurance providers and claimers in the healthcare sector can leverage fully automated or digitally smart contracts, providing a faster and improved health insurance system.



Well-implemented, improved blockchain systems promote perfectly synchronized transactions, & the technology best suits the requirements of the healthcare industry. It can be leveraged to enhance the flawless management of shared healthcare data through a digital transformation while ensuring the best security standards are in place. While it is still seen as an early-stage solution, it is worth considering Blockchain as a tool that is poised to offer smart authorization protocols, efficient diagnosis, and controlled medical data sharing.
