• Blockchain is potentially a way that medical records can be shared at the direction of patients. It has the advantage of not requiring the involvement of healthcare provider office staff every time a patient requests a release of records. How do you expect that patient consents to release records available through a blockchain will work?
  • Information to healthcare data can be stored directly on a blockchain. Alternatively, links to data stored elsewhere can be recorded on a blockchain. What healthcare information is best to store on the blockchain and what is best stored off the blockchain?
  • For a blockchain to be an effective way to share healthcare information, standardized data models will be needed. How to you see such models being adopted? Will metadata play a significant role in making shared data accessible?
  • Identifying patients by social security number is a common practice. Though rare, it sometimes happens that two people are issued the same social security number. The likelihood of two such people being patients of the same healthcare provider is extremely low. This allows manual interventions to keep the records of two such patients distinct. If medical records are stored on a blockchain in a fully automated way, then how would you propose to uniquely identify patients?
  • HIPAA requires personal health records to be confidential for 50 years after the patient’s death. Will this pose a problem for the confidentiality of records on a blockchain?
  • Occasionally, erroneous information is recorded in a medical record. If incorrect information gets into a blockchain-based medical record, what mechanism should be available to correct it and who should be able to provide corrections? How will this mechanism cope with medical identity theft?
