EHDS-aligned secondary use enablement

Governed FHIR and OMOP processing with manifest-backed traceability and controlled output pathways

Pontegra helps organizations implement EHDS-aligned secondary use workflows:

  • Secure analysis inside a SPE/TRE
  • Auditable access and processing with run manifests and lineage
  • Controlled outputs

All while enabling cohort building and dataset/feature extraction at scale and publishing dataset metadata to catalogs within EHDS networks.

Powered by: Studyfyr – The Governed Clinical Research Toolkit and Platform on FHIR and OMOP.

Case Study: This impact is proven at the University of Cologne, where we industrialized laboratory interoperability by scaling from a pilot to a production environment processing millions of laboratory records using Ignifyr. [Learn more]

Unifying Governed Processing and Publication

Secondary use programs are under pressure to deliver research value while maintaining governance, privacy, and auditability.

Common delivery gaps

  • Permit and policy requirements are not connected to day-to-day analytics execution
    • EHDS permits are documents, but execution needs operational controls
  • Secure processing controls and output controls are handled as separate systems
    • EHDS requires audit trails, but notebooks don’t generate manifests
  • Reproducibility and traceability are fragmented across tools and teams
    • EHDS requires airlock, but most TREs bolt this on late

This results in

12-18 month timelines, compliance incidents, researcher frustration.

Roles / Operating Model

Health Data Access Body (HDAB)

  • Evaluates secondary-use requests and issues permit/authorization decisions.
  • Defines approval conditions (purpose, allowed users, retention, policy constraints).

Health Data Holder

  • Provides access to approved data scope under organizational/legal controls.
  • Ensures provisioned study data matches authorized purpose and minimization rules.

Data User (Research Team)

  • Submits study request with purpose, population intent, and data requirements.
  • Executes approved analytics only within controlled workspace boundaries.

SPE/TRE Platform Operator (Studyfyr-enabled)

  • Binds request/approval metadata to executable controls in the runtime.
  • Enforces policy-aware pipelines, audit/manifest traceability, and controlled egress.
  • Promotes only approved outputs as immutable published artifacts.

Governance flow

Governance decisions are converted into machine-actionable study controls, so policy intent is preserved from request to execution to publication.

Permit-scoped analytics run in controlled workspaces, with reviewed outputs promoted as immutable published artifacts.
  • Onboarding: request and approval define purpose/scope.
  • Execution: processing stays in workspace with manifest/audit traceability.
  • Airlock: publish/export requires steward review and approval.
  • Promotion: approved outputs become immutable published artifacts.

From EHDS Documents to Executable, Auditable Study Operations

Studyfyr binds EHDS governance concepts to executable data operations on FHIR/OMOP, so approvals are not only documents but machine-actionable controls. Result:

  • Transparency: explicit request/approval-to-pipeline mapping.
  • Reproducibility: the same approved definitions execute deterministically.
  • Auditability: manifests and metadata audit events link decision, execution, and published outputs.
Narrative EHDS request/approval artifacts are bound to executable, policy-scoped FHIR/OMOP operations with traceable outputs.

Platform Capabilities

Secure Processing and Auditability

  • Governed study workspaces with explicit lifecycle boundaries.
  • Policy-driven minimization, anonymization, and pseudonymization controls.
  • SPE/TRE-ready Spark execution on study-scoped data under environment controls.
  • Manifest-backed run history and metadata audit events for traceability.

Controlled Outputs and Airlock Workflows

  • Workspace artifacts (for example, cohorts and datasets) remain inside controlled storage by default.
  • Publish/export actions require explicit review and approval (airlock-compatible flow).
  • Approved outputs are promoted as immutable snapshots with lineage and audit linkage.

FHIR- and OMOP-Based Analytics at Scale

  • Reproducible Spark processing foundations for secondary-use analytics.
  • Data access from FHIR APIs, OMOP databases, and FHIR/OMOP lakehouse storage
  • FHIR search/FHIRPath filtering and SQL-oriented extraction to analysis-ready tables.
  • Unified processing model across FHIR and OMOP sources.

Research Workflow: Cohorts -> Sampling -> Features

  • Repeatable cohort extraction with entry/exit/eligibility logic.
  • Sampling strategies for periodic and event-aligned timepoints.
  • Relational dataset preparation as reusable, well-defined tables/views.
  • Feature dataset generation for statistics and ML, including longitudinal/windowed features.
  • Deterministic run lifecycle supporting reproducibility and accountability.
