Drug Safety Signal Evaluation & Causality Assessment
Evaluate drug safety signals using structured causality assessment
What You Can Do
You systematically evaluate drug safety signals using structured causality assessment frameworks—applying WHO-Naranjo-Kramer methodologies, synthesizing real-world evidence from claims and EHR data, and generating regulatory-ready analyses. This skill transforms raw adverse event data into publication-quality evidence and compliant regulatory submissions with quantified confidence intervals and bias assessments.

Causality Assessment Summary
| Category | Score | Interpretation |
|---|---|---|
| WHO-UMC | Probable (8/13) | Temporal relationship strong; alternative explanations less likely |
| Naranjo | 8/13 | Probable adverse drug reaction |
| Strength of Association | OR 2.8 (95% CI: 1.9–4.1) | Statistically significant 2.8× increased risk |
Regulatory Finding: Signal meets EMA pharmacovigilance criteria for expedited review. Recommend risk minimization strategy targeting high-risk subgroups (age >65: OR 4.2; concurrent NSAIDs: OR 3.1).
Publication Statement: "Propensity-score adjusted analysis identified dose-dependent signal (p=0.003), unconfounded by renal function and drug interactions, supporting strengthened product labeling."
