Patient Data Sovereignty & Clinical Continuity

NorthHealth — Healthcare Provider Network

Executive Summary

We implemented a local‑first EHR and imaging architecture with sovereign identity and segmented LAN. The network recorded zero PHI incidents over 12 months and uninterrupted clinic operations during a regional WAN outage.

Challenge

Protect PHI with auditability across multi‑site clinics and specialties.
Minimize ransomware blast radius; enable fast restores without cloud dependency.
Keep clinician workflow simple with minimal login friction.

Sovereign Architecture Solution

Local‑first EHR/PACS; encryption in transit/at rest; MFA tokens for sovereign IAM.
Immutable backups and offline restore drills; append‑only audit trails.
ToT hygiene checks nurses can run in under 90 seconds.

Results

Zero PHI incidents in 12 months (third‑party audit verified).
45% reduction in IT overhead via simpler local workflows and fewer SaaS systems.
Regional WAN outage did not interrupt chart access or scheduling.
