Utility description: Clinical Report Consistency

Clinical Report Consistency Checker — Internal Report Consistency Validation

ℹ️ Utility performs automatic verification of molecular genetic report internal consistency according to CAP Molecular Pathology Checklist and CLIA:
• Numerical Consistency: Reconciliation of variant counts across table, summary, and narrative text.
• Logical Coherence: Verification that every actionable variant has corresponding therapeutic recommendation.
• Data Uniformity: Control of VAF, CNV, and gene nomenclature (HGNC) identity across all report sections.
• Structural Completeness: Presence of mandatory sections (disclaimer, methodology, test limitations).
• Navigation Integrity: Cross-reference validity and template version compliance.

⚠️ IMPORTANT:
• Contradictory data within a single report undermines physician trust in the entire laboratory.
• Missed therapy for actionable variant may cost patient's life.

Usage:
ClinicalReportConsistencyChecker.exe → demo mode (console output)
ClinicalReportConsistencyChecker.exe input.csv output.json → evaluate your data

Input format:
ReportID,PatientID,VariantsInTable,VariantsInSummary,ActionableVariantsInTable,TherapiesInRecommendations,AllActionableHaveTherapy,VAF_Consistent,GeneNomenclature_Consistent,HasRequiredDisclaimer,HasMethodologySection,HasLimitationsSection,CrossReferencesValid,ReportVersion,TemplateVersion

Example:
RPT-001,PAT-01,5,5,2,2,true,true,true,true,true,true,true,v4.1,v4.1

📍 Scope of Application (Usage Where):
• Molecular Laboratories: Final QC before pathologist signature.
• CDSS Systems: Automatic verification of generated reports.
• Quality Audit: Retrospective analysis of issued reports.
• CAP/CLIA Accreditation: Demonstration of reporting quality control system.

— WHY IS THIS NEEDED?
Molecular reports contain dozens of intersecting data points in different formats.
During manual preparation or complex templating, desynchronization is inevitable.
Automated verification eliminates "blind spots" and guarantees physician sees unified, non-contradictory picture.
This is the last line of defense against interpretation errors.

⚠️ CRITICAL:
• Variant Count Mismatch: Different variant counts in table vs summary = gross error.
• Missing Therapy: Actionable variant without recommendation = incomplete report.
• VAF Discrepancy: Different VAFs in table vs text question data reliability.
• Missing Disclaimer: Report without medical disclaimer is legally defective.

Key features:
• Seven-parameter consistency check
• Separation into critical errors and warnings
• Logical coherence verification (variant ↔ therapy)
• Report template version control
• Compliance with CAP Molecular Pathology Checklist

Critical parameters:
• Variant Count: Table == Summary
• Actionable-Therapy Link: 100% coverage
• VAF Consistency: Identical across sections
• Mandatory Sections: All present
• Template Version: Match

💡 Usage tips:
1. LIMS Integration: Automatically extract report metadata for verification.
2. Pre-signature Gate: Configure signature blocking upon INCONSISTENT status.
3. Templates: Use parameterized templates to minimize manual entry.
4. Trends: Monitor frequency of inconsistency types for process improvement.
5. Training: Pathologists must understand importance of consistency checks.

⚠️ Note: This utility verifies internal consistency, not clinical correctness. It does not replace molecular pathologist expertise but guarantees structural integrity of the report.

OQ-006	Verify batch/sample traceability.	Input and result identifiers match.
PQ-001	Verify 3–5 real user batches/samples.	Result is confirmed by QC/QA review.
PQ-002	Verify deviation workflow and manual QA decision.	Utility supports review but does not replace approved decision.

QA/QC and change control

Do not rename columns without updating validator, documentation and test set.
Retain input.csv, output.json, executable version and checksum.
Before production use, perform IQ/OQ/PQ or equivalent CSV/CSA verification.
Critical limits shall be verified against the approved specification, registration dossier and local SOPs.
The utility provides structured QC decision support; final release decision remains with QA/QP and approved procedures.
