LifeBand by Emberflow: Patient-Approved Medical Record Sharing Across Hospitals and Clinics
Built by Emberflow, LifeBand (currently a pre-commercial prototype) uses blockchain technology to record verified patient permission and access logs on-chain, while actual medical records stay privately stored off-chain at the patient's hospital or clinic.
Why Care Coordination Between Hospitals and Clinics Remains Fragmented
Every problem statement below is grounded in peer-reviewed medical studies and national healthcare data.
Incomplete Routine Exchange
Many hospitals still cannot routinely find and use outside patient records; in 2023, only 43% of U.S. hospitals routinely engaged in all four record-sharing steps (send, receive, find, and integrate), and 22% did not integrate outside records.
Repeat Scans and Lab Work
When prior imaging or lab results are unavailable across hospital boundaries during emergency visits, doctors often have to order repeat scans. Emergency department studies associate health record sharing with 44% to 67% lower relative rates of repeat imaging.
Computer & Paperwork Time
In a landmark clinical study, physicians spent nearly twice as much time on computer records and desk work (49.2%) as on direct face-to-face patient time (27.0%), while administrative spending accounts for 15% to 30% of U.S. health expenditure.
Scattered Patient Portals
Patients often have limited visibility into who views their medical records across separate clinic portals, and lack one simple place to grant or turn off clinic access with a clear permission log.
Reducing Care-Coordination Delays With LifeBand
A 2019 JAMA analysis estimated that failure of care coordination costs the U.S. $27.2B to $78.2B annually, alongside $265.6B in administrative complexity (Shrank et al., JAMA 2019). Separately, the 2024 CAQH Index identified a $20B annual industry savings opportunity from streamlining administrative workflows.

User-configured assumption (not a guarantee of savings)How Emberflow’s LifeBand Product Works
LifeBand records verified patient permission on-chain using blockchain while keeping all actual medical records privately stored off-chain at the patient's hospital or clinic.
Works Alongside Existing Clinic Software
LifeBand is designed to work alongside major hospital and clinic record systems (such as Epic, Oracle Health / Cerner, or athenahealth) without requiring clinics to replace their existing software or move their databases.
Medical Records Stay Off-Chain
In LifeBand, actual medical records, doctor notes, and lab results are never stored on the blockchain. They stay privately stored off-chain at the originating hospital or clinic and are shared only when patient permission is verified.
Verified On-Chain Permission Log
LifeBand uses blockchain technology to record a clear, permanent log of when a patient grants permission, turns off access, or when an emergency care team views their urgent summary.
LifeBand Prototype Highlights
Core capabilities demonstrated in Emberflow’s internal LifeBand test environment.
On-Chain Permission & Off-Chain Record Relay
In-house prototype demonstrating patient permission verification on-chain paired with direct record sharing between simulated clinic systems.
Sub-Second Permission Updates
In internal testing under controlled network conditions, simulated patient permission changes updated across connected clinic views in under 1 second.
Provider & Care Team Discovery
Ongoing clinical workflow conversations with healthcare providers and health-system specialists evaluating LifeBand for intake and referral handoffs.
