The collection of all info in one place is one part of the problem.

The other is that existing EMRs are receipts for insurance reimbursements, not true health documents. There's not going to be a standard way to code a previous abusive relationship.

A distributed ledger doesn't help with that, unfortunately the tail is wagging the dog and the centralized control lies with the insurance carriers rather than the providers. So the records fulfill their needs first and the patient's last.
