3. Current State of Healthcare EMRs
Provider maintains your data
Today, patients have no control over their medical records and can wait up to 60 days to receive their records from providers
Lack of Interoperability between providers
The current lack of interoperability costs 150,000 lives and $18.6 billion per year2 2. 3.
Insecure medical records
Hospitals are facing increasing crypto-ransomware attacks3

4. What is MedRec? Prototype developed by MIT media lab
Decentralized record management system for EMRs
Uses blockchain technology to manage authentication, confidentiality, accountability, and data sharing
3 types of “smart contracts” on Ethereum blockchain
Registrar Contract (RC)
Summary Contract (SC)
Patient-Provider Relationship
Contract (PPR)

5. How does it work?
Patient’s medical record is not be stored on the blockchain, instead data is “kept securely in providers’ existing data storage infrastructure.”
Identity confirmation via public key cryptography
Allows the use of already existing form of ID (e.g., SSN)
Contracts contain metadata about the record ownership, permissions and data integrity

6. Business Model Paid in data, not currency
Miners incentivized by census-level data
Average Iron levels for year old males
Enables greater clarity in research
Not driven by data power
Large agencies (CDC, NIH) are incentivized as are small, individual researchers
Not for monetary profit

7. What are the benefits?
Decentralized, single interface to allow patients to choose when/whom they share their data
Fast access to data for patients
Interoperability between healthcare providers – integrates with existing medical data storage infrastructure
Integrates personal health/fitness data (Fitbit, 23andMe, Apple HealthKit)

8. Next Steps From big idea to practical application
Aside from all risks associated with blockchain technology…(ex: bad actors, education)
High implementation barriers
Medical records are invaluable assets to hospital institutions, payers, etc.
EMR is still ‘new’ technology
Evolving health care ecosystem
Alignment of incentives
The best case scenario: major health systems + payers + set of ready-to-engage patients all come together to collaborate
MEDREC Prototype
Additional research
User testings
Partner with local health care institution
