Originally developed for cryptocurrency transactions, blockchain’s unique features—decentralization, immutability, transparency, and security—make it ideally suited to address some of healthcare’s most pressing challenges.
But what exactly is blockchain? It is a digital ledger that records transactions across multiple computers simultaneously. Once information is added to this ledger, it cannot be altered without changing all subsequent records, making it virtually tamper-proof. This feature alone has massive implications for an industry that handles sensitive patient data and complex supply chains.
Let’s look into the most promising applications of blockchain in healthcare that are revolutionizing the industry today!
1. Electronic Health Records (EHRs) Management
Perhaps the most impactful application of blockchain in healthcare is managing electronic health records. Currently, patient data is often scattered across multiple providers, making it difficult to access complete medical histories.
This fragmentation can lead to misdiagnosis, duplicate testing, and even medical errors—which Johns Hopkins University research identified as the third leading cause of death in the US!
Blockchain solutions like MedRec and Patientory are changing this landscape by:
- Creating a single, comprehensive source of patient medical records
- Enabling patients to control who can access their information
- Ensuring data integrity and security through encryption
- Allowing immediate, validated access to healthcare records
For example, BurstIQ’s platform helps healthcare companies manage massive patient data securely. It enables the safekeeping, sharing, or licensing of data while strictly complying with HIPAA rules. Because the platform includes complete information about patients’ health and healthcare activity, it could even help identify potential prescription drug abuse.
2. Pharmaceutical Supply Chain Management
Counterfeit drugs are a massive global health crisis. The blockchain’s ability to track items from manufacturing through the entire supply chain creates unprecedented transparency and security.
“The United States is expected to spend almost 20 percent of its GDP on healthcare by 2032 as high hospital costs, inefficient practices, and constant data breaches continue to plague the industry,” notes Sam Daley, highlighting the urgency for innovation in this space.
Companies like MediLedger and IBM Blockchain Transparent Supply are implementing blockchain to:
- Track pharmaceuticals from manufacturer to patient
- Verify drug authenticity and proper handling
- Create immutable records of temperature controls during transport
- Enable rapid responses to quality issues or recalls
For instance, Chronicled’s MediLedger network helps pharmaceutical companies ensure their medicines arrive efficiently while enabling authorities to review suspicious activity, such as drug trafficking. The system was so successful that in June 2023, the National Association of Boards of Pharmacy acquired the MediLedger Product Verification System to facilitate compliance with the Drug Supply Chain Security Act.

When implemented in clinical trials, blockchain technology can:
- Collect, store, and track clinical trial consent securely
- Make consent processes transparent and publicly verifiable
- Time-stamp consent forms, ensuring their authenticity
- Create a chronological audit trail of the entire consent process
5. Medical Insurance Claims Processing
Disputes, delays, and fraud often plague the health insurance claims process. In fact, according to Curisium, about 10% of claims are disputed, requiring lengthy manual resolution processes.
Blockchain technology offers a solution by:
- Creating immutable records of healthcare services
- Automating claims verification and processing through smart contracts
- Reducing administrative overhead and accelerating reimbursements
- Providing real-time tracking of claim status
For example, a study developed a blockchain-based medical insurance storage system that was displayed using Ethereum. In this system, medical insurance data can be encrypted and immutably stored, enhancing credibility and eliminating the need for third parties in managing patients’ health insurance.
