Blockchain is an emerging technology, and it will take time and research to fully determine how it could be applied to healthcare and what benefits it might offer. In this overview, you will learn about some of the general uses and applications of blockchain technology in healthcare. You’ll also get to know how blockchain works as a whole.
What is Blockchain Technology?
Blockchain is a digital distributed ledger. In simple words, it is a database shared across a computer network. This network is typically managed by a peer-to-peer network, meaning that there is no central authority that controls the database. Instead, each computer in the network that stores a copy of the database is known as a node.
Once a new transaction is added to the database, it is broadcast to all the network nodes. Each node then verifies the transaction and adds it to its own copy of the database. Once all nodes have verified the transaction, it is considered part of the blockchain.
The main benefit of blockchain technology is that it allows for trustless transactions. This means that two parties can transact without needing to trust or have a third party act as an intermediary.
For example, when you purchase with your credit card, you trust that the merchant will not charge you more than what you agreed to pay. With blockchain technology, however, the transaction would be recorded on the blockchain and could be verified by anyone who has access to it. This would eliminate the need for trust between parties and potentially reduce fraudulent activity.
Another benefit of blockchain technology is that it is decentralized, meaning there is no single point of failure. The rest of the network can operate without issue if one node goes offline. This makes blockchain networks much more resilient than traditional centralized information models.
Uses of Blockchain Technology in Healthcare
The potential of blockchain technology to transform healthcare is vast. Blockchain applications in healthcare are numerous, from streamlining clinical trials to improving data security. Below, we outline some of the most promising uses of blockchain technology in healthcare.
1. Clinical Trials:
Clinical trials are often marred by inefficiency and a lack of transparency. Blockchain for healthcare could address these issues by creating a decentralized database of trial participants. This would allow researchers to identify eligible patients and track their outcomes easily. In addition, a blockchain-based clinical trial platform would be tamper-proof, ensuring greater transparency and trustworthiness.
2. Data Security:
With the digitization of health information, patient data is at risk of theft or fraud. Blockchain in healthcare solves this problem through distributed ledger technology (DLT). Storing data on a decentralized network, DLT makes it much harder for hackers to access or tamper with sensitive information. In addition, each transaction on the blockchain is verified and recorded, making it easier to track down any unauthorized activities.
3. Drug Safety:
The supply chain for pharmaceutical drugs is long and complex, involving multiple parties across the globe. As a result, it can be challenging to ensure the safety and quality of drugs as they make their way from manufacturers to patients. Blockchain for healthcare could solve this problem by creating a transparent and tamper-proof record of each drug’s journey. This would allow stakeholders to track the progress of drugs through the supply chain and identify any potential problems. In addition, blockchain could verify the authenticity of drugs, ensuring that patients receive safe and effective medications.
4. Medical Records:
Presently, medical records are often stored in siloed systems, making it difficult for different healthcare providers to access and share information. Blockchain in healthcare could address this issue by creating a decentralized database of patient information. This would allow different providers to easily access and share data while ensuring its security and privacy. In addition, blockchain-based medical records can easily track patients’ progress over time, providing valuable insights into their health.
5. Telemedicine:
Telemedicine is a rapidly growing field that uses technology to deliver healthcare services remotely. Blockchain implementation in healthcare will improve the security and privacy of patient data in telemedicine. By storing data on a decentralized network, blockchain would make it much harder for hackers to access sensitive information.
In addition, each transaction on the blockchain would be verified and recorded, making it easier to track down any unauthorized activities. As a result, blockchain-based Telemedicine solutions for healthcare would be more secure and trustworthy, providing patients with greater peace of mind.
6. Wearables:
Many wearables collect sensitive health data, often stored on centralized servers. This creates a risk of data theft or fraud, as hackers could target these servers to gain access to this information. Blockchain healthcare provides a solution to this problem.
By storing data on a decentralized network, blockchain secures it from hackers or tampering. In addition, each transaction on the blockchain is verified and recorded, making it easier to track down any unauthorized activities. As a result, blockchain-based wearables would be more secure and trustworthy, providing patients with greater peace of mind.
7. Health Insurance:
Health insurance is another area where blockchain could have a significant impact. Health insurance claims are often processed manually, leading to errors and delays. Blockchain could address this issue by automating the claims process.
Virtual Healthcare Software and Blockchain
Healthcare is an industry that is ripe for disruption. Inefficiencies in the system are well-documented, and there is a growing consensus that something needs to be done to fix the problems. One area where healthcare could benefit from some innovation is Virtual Healthcare Software such as telehealth and telemedicine.
By creating a decentralized system for storing and sharing data, blockchain can help solve many challenges in virtual healthcare, such as patient data security, errors, and fraud.
In addition, blockchain could be used to create a virtual healthcare marketplace. This would allow patients to compare prices and services from different telehealth and telemedicine providers. It also allows providers to share information and resources, which helps to improve care quality overall.
Final Words
Blockchain is still in its infancy but shows much promise for healthcare applications. The main benefits of blockchain are its security, transparency, and immutability, which can help to improve patient care and data management.
While some challenges need to be addressed before blockchain can be widely adopted in healthcare, such as scalability and privacy concerns, the potential benefits make it worth exploring further.
Blockchain technology in healthcare can be both transformative and positively disruptive. We can only hope that healthcare leaders will embrace and implement it soon.
