HL7/FHIR Interoperability
Legacy EHRs use proprietary data formats. Modernizing requires FHIR (Fast Healthcare Interoperability Resources) implementation for multi-system data exchange.
AWS Application Modernization
Electronic Health Record (EHR) Modernization on AWS
Healthcare organizations run legacy EHR systems on expensive infrastructure. We modernize EHRs to cloud-native, interoperable platforms that improve clinical workflow and reduce operational costs.
- The current estate is inventoried.
- Assessment models post-migration TCO and a 7R path per workload.
- Rehost moves what should move as-is, with MGN or DMS where they fit.
- Refactor lands what should land on managed services or containers.
- Cutover waits for the agreed window.
- The workload is live on AWS with the roster still attached.
Key Challenges We Solve
Zero-Downtime EHR Migration
EHRs run 24/7. Healthcare cannot afford downtime. Migrating active patient data while maintaining service availability is extremely complex.
HIPAA Compliance During Migration
Migrating PHI to AWS requires BAA signing, encryption at every step, and audit trails of all data movements. One misconfiguration exposes patient data.
Our Approach
FHIR-First EHR Architecture
Cloud-native EHR using FHIR standards, HL7 protocol support, and AWS API Gateway for interoperability with other healthcare systems.
Staged Migration (Departments → Cloud)
Migrate one department/ward at a time while others remain on legacy EHR. Phased approach reduces risk and allows workflow adjustments.
HIPAA-Compliant Data Pipeline
Encrypted HL7 messages from legacy EHR → AWS Lambda → transformed to FHIR → RDS/DynamoDB. All steps encrypted and audited.
Frequently Asked Questions
What is FHIR and why does EHR modernization need it?
FHIR (Fast Healthcare Interoperability Resources) is the modern standard for healthcare data exchange. Legacy EHRs use proprietary formats; FHIR enables interoperability with other healthcare systems (labs, imaging, pharmacies). Modernized EHRs must support FHIR.
Can we migrate an EHR system without downtime?
Yes. Dual-run architecture (legacy EHR + new cloud EHR in parallel), with data synchronization between systems. Gradually migrate departments/wards, keeping legacy EHR as fallback until cloud EHR proves stable.
How does cloud EHR improve clinical workflow?
Cloud-native EHRs reduce system downtime, enable faster access to patient records (lower latency), support mobile/remote clinician access, and integrate with modern analytics and AI tools.
