EHR + Narrative ADE Detection Engine for Signal Triage

Surfaces probable ADEs from unstructured records to prioritize pharmacovigilance review Evidence basis: Recent Drug Safety reviews report consistent progress in NLP and ML ADE detection from free-text narratives; evidence supports faster triage and broader coverage while transportability varies by dataset quality

The Problem

“Detect probable adverse drug events from EHR narratives to accelerate pharmacovigilance triage”

Organizations face these key challenges:

1

Critical ADE evidence is buried in long unstructured clinical narratives

2

Structured diagnosis and billing codes undercapture true adverse events

3

Manual review is slow, costly, and inconsistent across reviewers

4

Drug-event causality and temporal linkage are difficult to infer at scale

5

Dataset quality and note style variation reduce model transportability

6

Regulated workflows require explainability, auditability, and controlled updates

7

Safety teams need high recall without overwhelming reviewers with false positives

Impact When Solved

Improves recall of probable ADEs missed by ICD-code-only workflowsReduces manual chart review volume by prioritizing likely positive casesSurfaces evidence spans and source notes to support reviewer trustAccelerates retrospective safety studies and postmarket signal triageSupports oncology and immune-related adverse event detection from free textEnables governed model updates for AI-enabled postmarket monitoring workflows

The Shift

Before AI~85% Manual

Human Does

  • •Review unstructured records manually for possible adverse drug events
  • •Coordinate case findings and follow-up actions in spreadsheets
  • •Prioritize records for pharmacovigilance review based on manual judgment
  • •Perform retrospective quality checks on completed reviews

Automation

  • •No AI-supported triage or detection in the legacy workflow
  • •No automated prioritization of probable adverse drug events
  • •No continuous monitoring of narrative records for review signals
With AI~75% Automated

Human Does

  • •Review AI-prioritized records and confirm probable adverse drug events
  • •Decide escalation priority for pharmacovigilance follow-up
  • •Handle ambiguous, incomplete, or high-risk cases requiring expert judgment

AI Handles

  • •Scan unstructured records to identify probable adverse drug event mentions
  • •Prioritize and queue records for pharmacovigilance review based on likely signal relevance
  • •Flag patterns and higher-risk narratives for earlier human attention
  • •Support broader and more consistent triage coverage across incoming records

Real-World Use Cases

Predetermined postmarket update planning for AI-enabled devices

A device maker plans in advance how its AI product can be updated after launch, and how it will keep checking that updates do not make the device less safe or effective.

Continuous learning governance without uncontrolled autonomous changeemerging but concrete, supported by recently issued final fda guidance on predetermined change control plans and reinforced by the new draft guidance.
