HL7 Engine

The HL7 Engine is a powerful component of the Centaur Data Platform, designed to efficiently process and manage HL7 messages. It serves as a crucial intermediary for routing, validating, and transforming HL7 v2.x and 3.x messages between various healthcare systems.

Seamless Message Routing​

  • Intelligent Queue Subscription: The HL7 Engine subscribes to designated queues, ensuring efficient handling of incoming HL7 messages
  • Event-Driven Processing: Leverages Container Apps to pick up and process messages as events occur, facilitating real-time data integration
  • Multi-System Routing: Routes HL7 messages between various provider systems, enhancing interoperability across your healthcare ecosystem.

Comprehensive ADT Message Support​

Processes a wide range of ADT (Admission, Discharge, Transfer) message types, including:

  • Admit/visit notifications (A01)
  • Patient transfers (A02)
  • Discharges/end visits (A03)
  • Patient registrations (A04)
  • Pre-admissions (A05)
  • Outpatient to inpatient conversions (A06)
  • Patient information updates (A08)
  • And many more

Advanced HL7 Validation​

  • Custom Validation Rules: Automatically executes defined custom validation rules, ensuring message integrity and compliance with your specific requirements
  • Event Type Verification: Extracts and validates ADT event types against supported types, ensuring only relevant messages are processed
  • Comprehensive Syntax Checking: Verifies correct HL7 syntax, including segment delimiters, field separators, and message length
  • Structure Validation: Ensures message structure aligns with the specific HL7 version in use (e.g., HL7 v2.5)
  • Data Type Validation: Checks that fields and components comply with HL7 data type specifications
  • Contextual Validation: Performs contextual checks to ensure message content makes sense within healthcare operations
  • HL7 OID Validation: Examines and translates numerical OIDs to human-readable source details using the HL7 OID registry

Intelligent Error Handling and Retry Logic​

  • Initial Retry Mechanism: Automatically attempts to retry failed messages after a 2-second delay, excluding valid rejects (ACK returns as AE or AR)
  • Structured Retry Storage: Failed messages are stored in a retry folder with a specific naming convention for easy tracking and management
  • Tiered Retry Scheduling: Implements a sophisticated retry mechanism with increasing intervals:
    • Every 1 minute (5 attempts)
    • Every 5 minutes (3 attempts)
    • Every 1 hour (24 attempts)
    • Every 15 minutes (2 attempts)
  • Efficient Cleanup: Successfully retried messages are automatically deleted from the retry folder
Organized Error and Retry Management
  • Structured Error Storage: Stores error messages in a hierarchical folder structure for easy access and analysis
  • Retry Folder Organization: Maintains retry messages in a structured format

Benefits of the HL7 Engine​

  • Enhanced Interoperability: Facilitates seamless communication between different healthcare systems by efficiently routing and processing HL7 messages.
  • Data Integrity: Rigorous validation ensures that only accurate and compliant HL7 messages are processed, maintaining high data quality.
  • Operational Efficiency: Automated routing, validation, and retry mechanisms reduce manual intervention and streamline healthcare data workflows.
  • Scalability: Designed to handle large volumes of HL7 messages, making it suitable for healthcare organizations of all sizes.
  • Flexibility: Supports custom validation rules, allowing adaptation to specific organizational needs and compliance requirements.
