Clinical Trial Adverse Event Analysis & Safety Reporting
Extract, classify, and report clinical trial adverse events with regulatory compliance
What You Can Do
You can systematically extract adverse events from unstructured clinical trial data, automatically classify them by severity and causality, and generate regulatory-compliant safety reports. The skill validates data quality, identifies safety signals, and maintains complete audit trails for FDA/EMA submissions. It accelerates the safety surveillance process while ensuring no critical events are missed.
Features
Identifies adverse events from narrative case reports, lab results, and clinical notes with high recall and precision using medical terminology recognition.
Applies standardized algorithms to classify events by severity (mild/moderate/severe/life-threatening), seriousness, and relatedness to study drug using regulatory guidelines.
Ensures all extracted data meets FDA, EMA, and ICH-GCP requirements with built-in checks for completeness, consistency, and reportability criteria.
Produces formatted safety reports compatible with regulatory submissions including narrative summaries, tables, and MedDRA coding recommendations.
Identifies emerging safety patterns, unusual event clusters, and temporal trends that may indicate new safety risks requiring escalation.
Flags missing data, inconsistencies, and incomplete case narratives that require follow-up, with severity prioritization for data managers.
Documents all extraction decisions, classifications, and modifications with timestamps and rationales for regulatory inspections and audits.

}
Example 2: Safety Report Summary
| MedDRA Preferred Term | N Events | Serious | Related | Grade 3-4 |
|---|---|---|---|---|
| Elevated Transaminases | 8 | 3 | 6 | 2 |
| Headache | 24 | 0 | 12 | 0 |
| Nausea | 19 | 0 | 14 | 1 |
| Rash | 5 | 0 | 4 | 0 |
Example 3: Signal Detection Alert
- ⚠️ Emerging Signal — Elevated liver enzymes + rash combination: 2 cases (1.3% incidence vs 0.2% background). Safety Committee notification required within 24 hours.
