ResearchStudy resource (study metadata)
ResearchSubject resources (participants)
QuestionnaireResponse resources (CRF data)
Observation resources (findings)
PlanDefinition resources (pathways, workflows)
Questionnaire resources (form definitions)
Audit events

Use Cases

Complete data backup
Regulatory submission
Data migration
FHIR-compatible analysis tools
Long-term archival

Format

{
  "resourceType": "Bundle",
  "type": "collection",
  "entry": [
    {
      "resource": {
        "resourceType": "ResearchStudy",
        ...
      }
    },
    ...
  ]
}

FHIR JSON preserves complete data structure and relationships. Use this format when you need full fidelity.

Column Headers Across CRF Versions

CSV column headers are built from the field’s stable identifier and name, not from the underlying FHIR resource id. As a result, an unchanged field is reported in the same column for participants on different CRF versions of the same study.

A field that exists in two CRF versions and was not renamed appears in one column for all participants, regardless of which version they are on.
A field that was renamed in a new CRF version appears under two separate column headers — one per name — because renaming a field is treated as a structural change.

Updating the data for an existing report changes the CSV header layout to match this behavior. Any saved filters, scripts, or downstream pipelines that reference the old per-version column names will need to be updated.
