Comprehensive Guide to Healthcare Integration Platform by Orion Health
Rhapsody is a healthcare integration platform (interface engine) that serves as the central nervous system for healthcare data exchange. It connects disparate healthcare systems, transforms data formats, and ensures seamless communication across the entire healthcare IT ecosystem.
Rhapsody eliminates the complexity of healthcare system integration by providing a centralized platform that handles all data exchange requirements, from simple message routing to complex data transformations and business process orchestration.
High-performance message routing engine capable of processing millions of healthcare messages daily with guaranteed delivery and error handling.
Visual mapping tools for converting between different data formats, including HL7 versions, DICOM, CDA, FHIR, and proprietary formats.
Comprehensive support for healthcare communication protocols including MLLP, HTTP/HTTPS, FTP/SFTP, file-based, and web services.
Advanced monitoring dashboard with real-time message tracking, performance metrics, and comprehensive alerting capabilities.
Without Rhapsody: N*(N-1)/2 integration points for N systems (exponential complexity)
With Rhapsody: N integration points for N systems (linear complexity)
For 10 systems: 45 point-to-point connections vs. 10 hub connections
