Blockchain in Healthcare – What You Need To Know


Blockchain technology has been used to store data and transact using cryptocurrency, but it can be used in healthcare as well to manage access to data and sensitive patient information in ways that both increase security and reduce the risk of fraud. In this article, we’ll discuss how blockchain works and how it can be applied to healthcare data management systems to improve efficiency, eliminate redundancies, and streamline communications between partners in care. By the end of this article, you’ll have all the information you need to know about blockchain in healthcare so you can make smart business decisions moving forward. Let’s get started!

The technology behind blockchain

In its most basic form, a blockchain is a digital ledger of transactions. These transactions can be anything of value—money, goods, property, or even votes. Once a transaction is recorded on the ledger, it cannot be altered or removed. This makes blockchain an incredibly secure way to store data. Blockchain’s decentralized design means that no single entity controls the information. Every party who participates in a blockchain has access to an up-to-date copy of the database and gets a say in what gets added to it. The use of this technology for health records could make them safer from tampering and theft, which often happens with current paper-based systems. For example, Harvard Medical School research showed that 1/3rd of all medical records are either falsified or stolen each year as they pass through multiple hands (including doctors, nurses, technicians, lab workers).

How blockchain can be used in healthcare

Blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as completed blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. The main verification process for a given bitcoin transaction is called mining. Miners group every valid transaction they receive into one or more blocks and then broadcast those blocks to other miners. They also start working on solving a difficult mathematical problem which can only be solved by guessing until you find the answer. For each guess, you get closer to solving this problem (called the proof of work). When you guess correctly (called a hash), you announce it to the rest of the network, who will then check your solution for correctness (called validating or mining). The network agrees that your proof was correct and assigns an area of newly mined bitcoins which had just been created as well as any associated fees and rewards.

Challenges and opportunities with blockchain

  1. As the healthcare industry continues to digitize, there is a growing need for improved data security and interoperability.
  2. Blockchain has the potential to address these challenges by creating a decentralized and tamper-proof record of data.
  3. However, blockchain technology is still in its early stages and there are several challenges that need to be addressed before it can be widely adopted in healthcare.
  4. These challenges include scalability, privacy, and regulatory compliance.
  5. Despite these challenges, blockchain holds great promise for the healthcare industry and there are already several pilot projects underway that are exploring its potential use cases.
  6. Some of these use cases include claims processing, patient data management, and clinical trials management.
  7. For example, using blockchain could potentially eliminate fraud from billing practices, as every transaction would have a timestamp and audit trail showing where the information came from and where it went.
  8. Another example is using distributed ledgers to enable greater coordination between different providers when exchanging health records so patients don’t have to request multiple copies of their own medical records from different providers.

Where is blockchain likely to take healthcare?

The potential for blockchain technology in healthcare is huge. From streamlining medical records to improving patient care, there are many ways that blockchain could revolutionize the healthcare industry. However, before blockchain can be fully integrated into healthcare, there are a few challenges that need to be addressed. In this blog post, we’ll take a look at what blockchain is, how it could be used in healthcare, and some of the challenges that need to be overcome before we see widespread adoption. What is Blockchain? Blockchain is a decentralized digital ledger that contains an immutable record of transactions across all computers linked to the network. It relies on cryptography to secure these transactions and prevent them from being altered or hacked. These blocks create chains – hence blockchain – which contain information about who sent or received each transaction as well as when they happened, making them publically available so anyone with access can see them. Once a block has been completed, another one cannot be added unless all members have agreed on it – keeping information accurate and transparent for everyone involved. Why Is Blockchain Important? Blockchain helps facilitate financial transactions without the need for a third party. Due to its transparency and decentralization, blockchain prevents fraud by making sure that no single person controls all of the data.

The future of blockchain in healthcare

The potential for blockchain technology in healthcare is huge. From improving patient care to reducing costs, there are many ways that blockchain could make a positive impact on the healthcare industry. However, before blockchain can be fully integrated into healthcare, there are a few things that need to happen. First, standards need to be developed so that all parties can agree on how data will be stored and accessed. Second, more research needs to be done to identify the best use cases for blockchain in healthcare. And finally, pilot programs need to be implemented to test out the feasibility of using blockchain in various aspects of healthcare. Once these steps have been taken, we’ll be able to see the true potential of blockchain in healthcare. It’s predicted that by 2022, 10% of healthcare organizations will be storing clinical information on blockchains. With this increased adoption, patients will have better access to their medical records and it’ll save hospitals time and money spent dealing with insurance companies.
