The healthcare industry is on the cusp of a revolution, driven by the potential of blockchain technology to transform the way medical data is stored, shared, and used. This is not a new concept; the Estonian government has already implemented blockchain to secure over 1 million citizen health records. However, the true value of blockchain in healthcare lies in its ability to systematically link the entire value chain, including the payment and transaction system, to health data.

This is achieved through a four-party ledger among consumer, provider, payer/insurer, and government, governed by smart contracts. The model has significant cost savings implications, supporting the development of a future expanded Healthcare Consortium. Portability, interoperability, and security concerns are also addressed, with Medicare and specific areas of utilization management serving as clear first use cases for using blockchain and related technology to transform healthcare.

The Four-Party Ledger: A Foundation for Healthcare's Future

The basic four-party ledger addresses the critical players in the current health data and transaction ecosystem, plus the inclusion of critical data for population health research. Each health service transaction contains interconnected data points, including receiver of care, giver of care, reason for service, service performed, date of service, place of service, cost of service, and associated health metrics and notes. The first party, the consumer, and the second party, the provider, in the ledger are part of that data. Connected to the receiver and giver of care are existing relationships that address the cost of service—managed through a third party payer/insurer and/or government programs.

The fourth party is a government entity that can use the transactions themselves, devoid of Protected Health Information (PHI), to analyze health data, or when permission is granted, enrich the data with other patient variables not found in a health service or by allowing a combination of health service transactions related to a single patient. This concept is illustrated in Figure 1, representing a block in the Health Services Ledger chain.

Blockchain's Role in Healthcare: Simplifying Data Analysis

Fundamentally, blockchain is a transaction ledger. The intelligence needed in analyzing data and finding meaning in health information to impact program development and improve outcomes would be processed through a different system, an AI/analytics engine. Blockchain merely provides the secure, unique, and uniform transactions that can simplify data analysis. This simplification could take Big Data to its next level of development, as the uniform, structured data it contains adds more accuracy to Big Data's current mix of structured and unstructured data.

The opportunity is to fast forward to an era beyond analytics into predictive analytics. For healthcare and medicine, the implications of more advanced predictive analytics could help realize the promise of precision medicine—knowing the likelihood of disease, injury, treatment success, and positive outcomes.

A Future Healthcare Consortium: Expanding Beyond the Major Players

Microsoft's Bletchley Project posits the existence of future consortiums that transact across several blockchain networks; that framework applied to healthcare links the entire supply chain of healthcare transactions. The creation of such a consortium would expand past the major players in the ecosystem, potentially including drug manufacturers and pharmacy/prescription tracking, medical equipment suppliers for consumers and providers, clinic appointment setting and optimization, and more.

These chains could be governed by a series of Smart Health Contracts. The Four-Party Ledger is also the foundation for exploring use of Melanie Swan's Health Coin concept for healthcare transactions, where services are "paid" for using a new cryptocurrency that could add needed price transparency, even normalizing pricing across healthcare.

Implementing Blockchain in Healthcare: Timing Considerations and Entry/Exit Strategies

The adoption of blockchain in healthcare is not a straightforward process. It requires careful consideration of timing, entry, and exit strategies. The initial result is a four-party ledger among consumer, provider, payer/insurer, and government governed by smart contracts. This model has significant cost savings implications, supporting the development of a future expanded Healthcare Consortium.

To implement blockchain effectively in healthcare, it is essential to consider the following factors: the type of data being stored, the level of security required, and the scalability of the system. It is also crucial to address common implementation challenges, such as the lack of standardization in healthcare data and the need for interoperability between different systems.

A New Era for Healthcare: Predictive Analytics and Precision Medicine

The potential of blockchain in healthcare is vast, and its impact will be felt across the entire industry. By providing a secure, transparent, and efficient way to store and share medical data, blockchain has the potential to revolutionize the way healthcare is delivered. With the ability to predict disease, injury, treatment success, and positive outcomes, healthcare professionals will be able to provide more effective care, and patients will be able to make more informed decisions about their health.

This is not a distant future; the momentum is growing, with the FDA actively working with IBM on a proof of concept for blockchain use in clinical trials. The future of healthcare is bright, and blockchain is at the forefront of this revolution.
