Integration

Integration patterns focus on legacy modernization and capability management, enabling gradual transition from legacy systems to modern FHIR-based architectures.

Integration patterns address the challenges of healthcare system modernization:

  • Legacy system integration while preserving clinical semantics
  • Incremental modernization strategies that minimize disruption
  • Capability abstraction for simplified system interaction
  • Semantic preservation during data transformation

The Integration provide essential capabilities:

Legacy Adapter

Transform legacy data formats (HL7v2, CDA, DICOM SR) to FHIR while preserving clinical semantics and enabling incremental modernization of healthcare systems.

Key Benefits: - Semantic Preservation: Maintains clinical meaning during transformation - Incremental Migration: Enables gradual modernization without disruption - Standards Compliance: Produces valid FHIR resources with proper profiles - Terminology Mapping: Handles code system translations automatically

Capability Facade

Provide a simplified interface for querying and managing FHIR server capabilities and configuration, abstracting the complexity of CapabilityStatement parsing.

Key Benefits: - Simplified Queries: Easy to check capabilities without parsing CapabilityStatement - Caching: Capability information cached for performance - Aggregation: Combine capabilities from multiple servers - Abstraction: Hide complexity of capability discovery
