Blockchain in Healthcare Benefits: What You Need to Know

Hospitals and clinics manage a huge amount of patient data every day, but the systems they use don’t always connect well. This can lead to delays in care, mistakes in records, and even data breaches. Patients also have little control over who sees their information, which can make them lose trust in the system.

One technology, blockchain, best known for powering cryptocurrencies, is now being tested in healthcare with the promise of fixing these issues. Early projects suggest it could make records more secure, easier to share, and more trustworthy—but how?

Well, you’re in the right place to know more. Read on as we cover:

At the end of this article, you’ll know how blockchain can make healthcare more secure, efficient, and trustworthy.

Understanding blockchain in healthcare

At its core, blockchain is a secure list of records that is shared across many computers. Every time new information is added, it's stored in a "block" that is linked to the previous one, creating a chain. Once a block is added, it can't be changed without the approval of everyone in the network. This makes the data more secure and harder to tamer with.

This technology has particular promise for healthcare, where data security and integrity are critical. In traditional healthcare IT systems, patient records are usually stored in a single database managed by one hospital, clinic, or company. If that system is hacked or data is accidentally changed, there's often no easy way to trace the problem. Blockchain addresses these vulnerabilities by spreading the data across a network, using encryption for protection, and creating a permanent, time-stamped history of every change.

Blockchain in healthcare is still new but growing fast. Valued at just over $1 billion in 2023, the market is expected to multiply by the mid‑2020s, with annual growth of 22% to nearly 40%. By 2025, up to 40% of healthcare providers could be using it for tasks like securing records, processing claims, and managing medical supply chains.

Key blockchain in healthcare benefits

Aside from stronger data security, blockchain brings a range of other advantages that can improve how healthcare systems work.

Better interoperability between systems

As mentioned earlier, one of the biggest challenges in healthcare is that different systems often can’t “talk” to each other. A hospital’s electronic medical records might not connect with a specialist’s clinic or a diagnostic lab, forcing staff to rely on slow, manual processes like fax or email. Blockchain can bridge these gaps by creating a shared, secure platform where authorized providers can access the same patient information in real time.

For example, a lab could upload test results to a blockchain, allowing a primary care doctor to review them instantly without waiting for a file transfer or risking errors from manual entry. This not only speeds up treatment but also ensures everyone is working with the most accurate, up‑to‑date information.

Enhanced patient control over data

Patients today have more ways to view their health records, but access is still not consistent for everyone. In the U.S., for instance, over 77% of people were offered online access in 2024, and nearly 65% used a portal or app at least once, yet many still face barriers like limited technology, complex systems, or low health literacy.

Blockchain gives patients direct ownership of their data, allowing them to decide who can see it, for how long, and for what purpose. For example, a patient could grant a specialist one‑time access to their medical history through a blockchain‑based portal, then revoke it instantly once the consultation ends. This level of control helps protect privacy, reduces the risk of misuse, and builds trust between patients and healthcare providers.

Fraud prevention and compliance

Healthcare fraud, from inflated billing to false insurance claims, costs the industry billions each year and can slow down legitimate claims. Compliance with strict regulations, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States and the General Data Protection Regulation (GDPR) in the European Union, also demands accurate record‑keeping and clear audit trails. Blockchain supports both goals by automatically recording every transaction in a time‑stamped, tamper‑proof ledger that can be reviewed at any time.

For example, a blockchain‑powered insurance claims system could flag unusual billing patterns or duplicate submissions before payments are made. This not only helps prevent fraud but also speeds up legitimate reimbursements and ensures providers stay compliant with regulatory standards.

Supply chain transparency in healthcare

Medical supply chains are complex, often involving multiple manufacturers, distributors, and healthcare providers. Without strong oversight, there’s a risk of counterfeit drugs, stolen medical devices, or delays that can impact patient safety. Blockchain creates an unchangeable record of each step in the supply chain, making it possible to track products from the point of manufacture all the way to the patient.

For example, in a vaccine distribution program, blockchain can log every handoff—from the factory to transport trucks, storage facilities, and finally to clinics—while verifying that proper storage temperatures were maintained. This level of traceability helps prevent counterfeit medications from entering the system, reduces waste, and builds trust in the quality and safety of medical products.

Challenges and considerations

While blockchain offers promising benefits, adopting it in healthcare is not easy. Here are some things to consider, as well as how to address them.

High implementation costs: Setting up blockchain systems requires investment in infrastructure, software, and staff training. Starting with small‑scale pilot projects in high‑impact areas, such as supply chain tracking or claims processing, can prove value and build the case for wider adoption.
Integration with legacy systems: Many healthcare organizations still rely on outdated IT platforms that don’t easily connect to blockchain networks. Middleware or application programming interfaces (APIs) can help bridge these systems in the short term, while phased upgrades ensure long‑term compatibility.
Balancing privacy with accessibility: Blockchain’s transparency must be balanced with strict patient confidentiality requirements. Middleware or application programming interfaces (APIs) can help bridge these systems in the short term, while phased upgrades ensure long‑term compatibility.

Conclusion

Blockchain in healthcare offers clear benefits: stronger data security, better system interoperability, greater patient control, fraud prevention, and improved supply chain transparency. Together, these advantages can make healthcare more secure, more efficient, and more trustworthy for both providers and patients.

As the technology matures, its role in healthcare will likely expand from niche projects to everyday operations. Providers who understand its potential today will be in a stronger position to deliver safer, faster, and more transparent care in the future.
