Clinical Data Mesh for a 28-Hospital Network
Unifying fragmented clinical, operational, and financial data across a regional hospital network into a federated data mesh — enabling AI-driven clinical decision support and population health management at scale.
The Challenge
The health system had accumulated 28 distinct EHR implementations across its network following a decade of acquisitions, with no data interoperability between facilities. Clinicians treating patients across sites had no access to complete medical histories, and population health programmes were running on export-and-email workflows.
HIPAA requirements and state privacy laws across three jurisdictions created a compliance landscape that ruled out centralising patient data — demanding a federated architecture that enabled analytics without data movement.
The Strategic Solution
FHIR-Based Data Fabric
Implemented a FHIR R4-compliant API layer across all 28 EHR instances, creating a unified clinical data fabric that enables real-time data access across the network without requiring centralisation.
Federated Analytics Platform
Deployed a federated query engine enabling population health analysts to run aggregate queries across the entire patient population without any patient data leaving its originating facility — satisfying HIPAA requirements across all jurisdictions.
AI Clinical Decision Support
Trained sepsis, readmission, and deterioration risk models on the federated data fabric, deploying real-time clinical alerts directly into clinician workflows across all hospital sites.
Measurable Outcomes
Reduction in 30-day readmissions via AI-driven discharge risk scoring.
Earlier average sepsis detection versus pre-deployment baseline.
HIPAA violations or data sovereignty breaches throughout the programme.
We had 28 data silos and no way to see our patients as whole people across the network. Agradiant gave us that. The clinical impact was measurable within the first quarter.
