The Clinical Data Quality Hierarchy:
| Priority | Quality Gate | Question | Pass Criteria | Fail Action |
|---|---|---|---|---|
| 1 | Critical Data | Are safety and efficacy data accurate? | 100% verified source data, no critical queries open | STOP: Do not lock; investigate immediately |
| 2 | Protocol Compliance | Is data collection per protocol? | CRF completion ≥ 95%, visit windows met | STOP: Data review meeting; assess impact |
| 3 | Consistency | Are data internally consistent? | Cross-form checks pass, no logical discrepancies | STOP: Issue queries; resolve contradictions |
| 4 | Completeness | Is all required data present? | Missing data < 5% for required fields | STOP: Site follow-up for critical missing |
| 5 | Timeliness | Is data entered promptly? | Entry within 10 days of visit | STOP: Site compliance discussion |
| 6 | Traceability | Can data be reconstructed? | Complete audit trail, eCRF-sourced | STOP: Documentation review |
Query Priority Matrix:
| Priority | Query Type | Response Time | Escalation |
|---|---|---|---|
| Critical | Safety data, primary endpoint | 24 hours | Medical monitor, PI notification |
| High | Key secondary endpoints, eligibility | 5 business days | Site monitor, data coordinator |
| Medium | Demographics, medical history | 10 business days | Site coordinator |
| Low | Administrative, non-critical | Next visit | Routine follow-up |
Pattern 1: Prevention Over Detection
Build quality in from the start:
├── EDC design: Edit checks, branching logic, field validation
├── Training: Site staff on CRF completion
├── Central monitoring: Statistical triggers, anomaly detection
├── Real-time review: Query generation within days of entry
└── Risk-based monitoring: Focus on high-risk sites/data
Detecting errors is expensive; preventing them is efficient.
Pattern 2: Source Data Verification Strategy
Optimize SDV through risk assessment:
├── Critical data: 100% verification (safety, efficacy)
├── Important data: Targeted verification (random sampling)
├── Administrative data: Reduced verification (spot checks)
├── High-risk sites: Increased SDV frequency
└── Low-risk sites: Centralized monitoring approach
Align SDV intensity with patient risk and data criticality.
Pattern 3: Standardization for Efficiency
Reuse and harmonize across studies:
├── Global library: Standard CRFs, edit checks, dictionaries
├── CDISC standards: CDASH for collection, SDTM for submission
├── Controlled terminology: MedDRA, WHODrug, CDISC CT
├── Master protocols: Common designs, shared controls
└── Automated processes: SAS macros, validation scripts
Standards enable speed without sacrificing quality.
Pattern 4: Traceability and Audit Readiness
Every data point must be defensible:
├── Audit trail: Who changed what, when, why
├── Version control: Protocol amendments, CRF versions
├── Data lineage: Raw → Clean → Analysis → Reporting
├── Documentation: Specifications, decisions, rationales
└── Reconstruction: Ability to reproduce any result
Regulators will ask; be prepared to answer.
