Pipeline

Pipeline patterns focus on data processing and transformation workflows that handle the movement, transformation, and governance of healthcare data.

Pipeline patterns address the complex requirements of healthcare data workflows:

  • Audit and provenance tracking for regulatory compliance and data lineage
  • Population-scale data export for research and analytics
  • De-identification and privacy preservation for secondary use scenarios
  • Asynchronous processing for long-running operations

The Pipeline provide essential capabilities:

Audit & Provenance Chain

Implement end-to-end audit logging and provenance tracking through a chain of responsibility pattern, enabling comprehensive traceability for regulatory compliance.

Key Benefits: - Comprehensive Tracking: Complete audit trail from request to response - Standards Compliance: Implements IHE ATNA/BALP requirements - Data Lineage: Provenance resources track data origins and transformations - Regulatory Support: Supports HIPAA, GDPR audit requirements

Population Export Pipeline

Orchestrate large-scale data extraction using FHIR Bulk Data APIs with proper authentication and transformation, enabling research and analytics use cases.

Key Benefits: - Scalable Extraction: Handle population-level data volumes - Standards-Based: Built on FHIR Bulk Data specification - Secure: Uses SMART Backend Services authentication - Flexible: Support for filtering, transformation, and multiple destinations

De-Identification Adapter

Apply consistent de-identification transformations across FHIR and DICOM data for secondary use scenarios, enabling research while preserving privacy.

Key Benefits: - Consistent Processing: Same rules applied to FHIR and DICOM - Policy-Driven: Flexible rules for different use cases - Pseudonymization: Maintain linkage while protecting identity - Standards-Based: Follows HIPAA Safe Harbor and Expert Determination

Asynchronous Invocation

Handle long-running FHIR operations through asynchronous job management and polling, enabling non-blocking execution of time-consuming processes.

Key Benefits: - Non-blocking Operations: Clients don't wait for long-running processes - Resource Management: Server resources allocated efficiently for long tasks - Progress Visibility: Real-time status and progress information - Fault Tolerance: Retry logic and error handling for unreliable operations
