"But through the blockchain private key mechanism, patients could own their medical records and share information with health care organizations much more seamlessly and securely. Blockchain is not a panacea, but it could present a paradigm shift for the way the health care ecosystem treats medical records today."
"HHS is right to track this rapidly evolving field to identify trends and areas where government support may be needed for the technology to realize its full potential in health care," said Dan Housman, managing director, Deloitte Consulting LLP, and chief technology officer of ConvergeHEALTH by Deloitte. "A blockchain-enabled, trusted exchange of health information can provide longitudinal views of patients' health, generate new insights about population health and support the move toward value-based care."
In its response, Deloitte addresses six current Health Information Exchange (HIE) pain points, and opportunities for blockchain to address them:
Six HIE pain points and the potential of blockchain technology:
- Difficulty in establishing a trust network: Participants' access to the distributed ledger would maintain a secure exchange without complex brokered trust
- Cost per transaction: Blockchain's disintermediation and near real-time processing could reduce costs
- Lack of a Master Patient Index: Blockchain's distributed, secured patient digital identities would bring together separate systems that all store different parts of patients' health records
- Varying data standards: Blockchain can improve interoperability between systems as it can enable data sharing in near real-time across the network to all parties
- Limited access to population health data: Distributed, secure access to patient health data across the distributed ledger
- Inconsistent rules and permissions: Smart contracts create a consistent, rule-based method for accessing patient data that can be permissioned to selected health organizations
Additionally, Deloitte lays out a four-step framework for health care leaders to evaluate opportunities to adopt blockchain technology:
- Initiate: Identify the right pre-conditions for using the technology
- Design: Determine which of the two primary use cases to consider: verify and authenticate information; or transfer value
- Strengthen: Consider smart contracts that automatically execute when conditions are met
- Implement: Choose a permission-less or a permissioned blockchain and select a blockchain protocol that guides the structure of the blockchain and development of applications
To help advance HHS' future use of blockchain technology, Deloitte describes how HHS could map and convene the blockchain ecosystem that could coordinate early adopters and support a consortium for dialogue and discovery.
In the U.S. and around the globe, Deloitte has been a leading voice on the transformative potential of blockchain technology. Earlier this year, Deloitte announced alliances with five blockchain startups and built 20 blockchain prototypes to service industries including insurance, employee management and cross-border payments. Deloitte's new blockchain offering guides clients through innovation and ideation, strategy development, prototyping and product development.
