Chiesi - AI Pharmacovigilance Literature Analysis System

Project Overview

An intelligent literature analysis system designed for Pharmacovigilance (PV). It automates the screening of medical literature to identify company products and assess safety information, ensuring compliance and patient safety while significantly reducing manual workload.

Industry Pain Points

High Volume of Literature

Pharmacovigilance teams must monitor a vast amount of global medical literature daily. Manual screening is labor-intensive and inefficient.

Risk of Missed Safety Signals

Identifying adverse drug reactions (ADRs) and special situations (e.g., overdose, pregnancy use) requires high precision. Manual review runs the risk of missing critical safety signals.

Standardization & Traceability

The regulatory requirement for PV is strict. Manual processes often lack consistent scoring standards and traceable audit trails for decision-making.

Innovative Solution

Core Methodology

The system employs a multi-stage AI pipeline to process literature:

1. Automated Retrieval & Matching: Automatically retrieves literature meta-data via APIs and matches them against the company's product catalog.
2. AI Relevance Scoring: The system downloads PDFs and uses NLP to analyze content, learning from historical data to calculate a relevance score (0-100%) for each article regarding company products.
3. Safety Signal Detection: Automatically identifies "Safety Information" (e.g., side effects).

Identified: Auto-tag as "Contains Safety Info". Clean: Auto-tag as "No Safety Info".

* Uncertain: Triggers a "Human-in-the-loop" workflow, sending email alerts with the document ID and reasoning to experts for manual review.

Technical Implementation

• AI-Driven Analysis: Utilizing Large Language Models (LLMs) to perform semantic analysis on full-text PDFs.
• Active Learning: The scoring engine iteratively improves by learning from 100% relevant historical cases, capturing context patterns and keywords.
• Intelligent Assistant: Integrated AI Agent + MCP (Model Context Protocol) to enable natural language semantic search and Q&A across the literature database.

Value Delivered

• Efficiency: Automates the initial screening of thousands of documents, allowing experts to focus only on high-risk or uncertain cases.
• Compliance: Ensures no potential safety signal is overlooked through rigorous AI scanning and automated alerting.
• Agility: The semantic search capability allows teams to quickly retrieve specific safety data or historical cases using natural language.
