Evidence Capsules

An Evidence Capsule is a purpose-scoped, provenance-complete, consent-bound unit of clinical evidence. It is the fundamental data structure of the EvidenceOS platform:

{
  "capsule_id": "uuid",
  "patient_id": "[de-identified]",
  "capsule_type": "Acute_Assessment_Capsule",
  "clinical_data": { "gcs_total": 10, "mechanism": "M1_blunt_road", ... },
  "provenance": {
    "source_study_dois": ["10.xxxx/...", ...],
    "evidence_grade": "GRADE_2B",
    "synthesis_run_id": "uuid",
    "evoe_score": 0.08
  },
  "consent": { "consent_id": "uuid", "scope": ["clinical_care", "research_contribution"] },
  "recommendation": {
    "action": "admit_icu",
    "confidence_set": ["admit_icu", "admit_observation"],
    "conformal_coverage": 0.91
  }
}

Contributing

The Evidence Capsule schema is open for community extension. Health system implementers can contribute:

• Implementation experience reports
• FHIR R4 mapping extensions
• Country-specific consent vocabulary adaptations
