A Guide to Blockchain Applications in Healthcare

With the ability to reduce costs, protect patient data, and improve patient and health workers’ overall experience, blockchain is a powerful solution to various persistent pain points in the healthcare industry.

Blockchain technology has a wide range of applications and uses in this sector, from facilitating the secure transfer of patient medical records and managing the medicine supply chain to the outbreak of diseases and helping healthcare researchers unlock genetic code.1

Many healthcare organizations within a region, community, or system mobilize healthcare information electronically. This is known as a health information exchange, or an HIE. Let’s explore the essential facts around enhancing and improving your HIE with blockchain technology.

The basics of blockchain

Blockchain is a distributed, decentralized, public ledger that stretches across a computer network. There are six general, but well-defined steps in any blockchain: 2

How blockchain can optimize healthcare

Blockchain technology can be transformative in healthcare. It can help achieve:3

  • Security
  • Privacy
  • The integration of health data

Capitalizing on this technology can connect fragmented systems to generate insights and assess the value of care more effectively. In the long term, a nationwide blockchain network for electronic medical records may improve efficiencies and support better health outcomes for patients.

Blockchain offers the opportunity for a new technological model in an HIE that makes electronic medical records more efficient and secure. It can also reduce or eliminate the friction and costs of current intermediaries.

Types of HIE health data

HIE data is used to improve the quality of healthcare, prevent errors, and increase the efficiency of administration. It includes:4

  • Patient health information
  • Electronic health records
  • Data collected from Internet of Things (IoT) devices or monitoring systems
  • Medical insurance claims
  • E-prescribing
  • Electronic dental records
  • Secure messaging

Data breaches hit the healthcare industry hardest

According to the 2021 data breach report, the healthcare segment continues to be targeted by cyber criminals, having experienced more breaches than any other industry sector in 2021.5

In the first six months of 2021, 238 healthcare data breaches were reported.

In a forecast of healthcare and blockchain trends up until 2025, it was found that blockchain can reduce $100 billion in annual costs for data breaches, IT, operations, support functions, personnel, fraud, and insurance.6

Blockchain offers a solution to cyberattacks by decentralizing the domain name system (DNS) entries. By applying decentralized solutions, blockchain removes the vulnerable single points exploited by hackers.

Eight benefits of blockchain in healthcare

Before you invest in blockchain, it’s critical to assess the risks versus the rewards of introducing the technology into a healthcare system. Let’s start with the benefits:7

Six barriers to blockchain in healthcare

Introducing blockchain innovations into this industry isn’t without its challenges. Be aware of these commonly encountered limitations: 8

Seven healthcare companies leading the way in HIE and blockchain

Take a look at these seven companies, which are pioneering diverse blockchain applications in healthcare today.

Look beyond blockchain technology in healthcare

To appreciate blockchain’s various applications in healthcare, it’s important to understand how this type of distributed ledger technology works, and how it can be applied practically to the broader healthcare ecosystem, whether improving processes or enabling employees to realize their professional goals.

While blockchain currently helps healthcare professionals to conveniently maintain extensive patient records, the advantages must be considered within the scope of pervasive challenges.

It’s clear that blockchain has started to disrupt, innovate, and reimagine healthcare and the world of work, and will continue to do so in the future. With any technology – and particularly blockchain – it’s critical to keep up to date with the latest developments.
