Pharmacoepidemiology Signal Detection & Safety Analysis
Detect and characterize drug safety signals with pharmacoepi rigor
What You Can Do
You leverage pharmacoepidemiology methodology to automatically detect potential safety signals from adverse event data, perform statistical significance testing, and generate evidence-based safety characterizations. Claude analyzes disproportionality metrics, temporal trends, and risk stratification to support regulatory decision-making and clinical trial monitoring with peer-reviewed methodology.
Features
Calculate ROR (Reporting Odds Ratio), PRR (Proportional Reporting Ratio), and IC (Information Component) with confidence intervals to identify adverse events reported more frequently than expected
Apply frequentist and Bayesian methods to determine whether detected signals meet statistical thresholds for further investigation and regulatory escalation
Identify acceleration or deceleration of adverse event reporting over time, with seasonal adjustment and anomaly detection for emerging safety concerns
Segment signals by patient subgroups (age, comorbidities, concomitant medications, dose) to identify at-risk populations and refine safety characterization
Flag incomplete narratives, duplicate reports, data entry errors, and missing covariates that could bias signal detection or confound causality assessment
Organize narratives for manual causality scoring using WHO-UMC or Naranjo criteria, with automated highlighting of key temporal, dechallenge/rechallenge, and alternative cause evidence
Produce formatted safety narratives, risk-benefit summaries, and expedited reporting templates (IND safety reports, MedWatch, EudraVigilance) ready for submission
Synthesize signals across clinical trials, EHR data, insurance claims, and public adverse event databases with source-specific weighting and conflict resolution
Example Output
Signal Detection Summary (Hypothetical):
- Adverse Event: Hepatotoxicity (Standardized MedDRA Query)
- ROR (95% CI): 2.8 (2.1–3.7), statistically significant
- Number of Cases: 42 observed vs. 15 expected
- Temporal Trend: Steady reporting over 18 months; no acceleration
- High-Risk Subgroup: Patients ≥65 years old (ROR 4.2) and those on concomitant statins (ROR 3.5)
- Data Quality: 95% complete narratives; 1 duplicate flagged for deduplication
- Recommendation: Signal confirmed. Escalate to pharmacovigilance committee; consider REMS restriction for high-risk populations
Causality Assessment Narrative (Excerpt):
Case #AR-2026-0847: 68-year-old female, AST/ALT elevated 5× ULN on study day 43, improved post-dechallenge (day 58), re-elevated on rechallenge (day 71). Alternative causes ruled out (no viral serology, no acetaminophen exposure). WHO-UMC assessment: Probable.
Regulatory Report Excerpt (FDA IND Safety Report):
In this interim analysis of Trial XYZ, 42 cases of drug-induced liver injury (DILI) were identified across 5,000 patient-exposures (incidence 0.84%). Disproportionality analysis shows statistically significant signal (ROR 2.8, 95% CI 2.1–3.7). Risk is substantially elevated in patients ≥65 years co-prescribed statins. We recommend amending the protocol to exclude or intensify monitoring in this subgroup.
