Overview
A regional hospital chain had grown through acquisitions, inheriting 8 different EHR systems that couldn't communicate with each other. Physicians treating patients who had visited multiple facilities couldn't access complete medical histories, leading to duplicate tests, medication errors, and fragmented care.
Koyal Tech Solutions designed and implemented an integration platform that created a unified view of patient data across all facilities while preserving investments in existing systems.
The Challenge
- System Heterogeneity
Eight different EHR platforms (Epic, Cerner, Meditech, etc.) with incompatible data formats and APIs.
- Patient Matching
Same patients existed with different identifiers across systems, making it difficult to consolidate records accurately.
- Real-Time Requirements
Clinical workflows required sub-second response times for patient lookups in emergency situations.
- Compliance Obligations
HIPAA, HITECH, and state regulations required careful handling of protected health information.
Our Solution
Healthcare Integration Engine
Built a FHIR-compliant integration platform using MuleSoft that connects all EHR systems through standardized APIs, transforming data formats in real-time.
Master Patient Index
Implemented an advanced patient matching algorithm using probabilistic matching techniques to accurately link patient records across systems with 99.7% accuracy.
Unified Clinical Portal
Created a web-based clinical portal that provides physicians with a consolidated view of patient data from all source systems, accessible from any workstation.
Clinical Alerts System
Built a rules engine that monitors data across systems to generate alerts for drug interactions, duplicate orders, and care gaps.
Results & Impact
30% Faster Decisions
Physicians access complete patient history in seconds rather than making calls between facilities.
45% Fewer Duplicate Tests
Visibility into prior tests across facilities eliminated unnecessary repeat diagnostics.
22% Reduction in Adverse Events
Real-time drug interaction alerts and complete medication histories improved patient safety.
95% Physician Satisfaction
Clinical staff overwhelmingly positive about improved access to patient information.
"For the first time, I can see a patient's complete history regardless of which of our hospitals they've visited. This integration has fundamentally improved how we deliver care."
