AI for ADR Detection
AI's role in detecting adverse drug reactions has evolved significantly, moving from statistical methods to NLP and deep learning. This enhances efficiency and accuracy in identifying safety signals from diverse data sources.
Early AI applications, like BCPNN and MGPS, improved signal detection in SRS but faced challenges with rare events and false positives. Modern approaches leverage NLP for unstructured data (social media, EHRs) and knowledge graphs to integrate diverse sources, achieving higher AUCs (e.g., 0.92 for knowledge graphs, 0.96 for multi-task deep learning). Multi-modal deep learning integrates visual cues and text, improving ADR detection accuracy and lead-time. However, interpretability and data quality remain key challenges.
Signal Detection & Active Surveillance
AI and ML methodologies enhance signal detection beyond traditional disproportionality analysis, enabling more proactive and real-time monitoring of drug safety.
AI models, like Gradient Boosting Machines, significantly outperform traditional disproportionality methods (AUC 0.95 vs 0.55 or lower). They streamline regulatory intelligence and extract information from various sources to identify safety signals faster. Systems like FDA's Sentinel use ML for post-market surveillance, achieving unprecedented speed and efficiency. Real-time EHR monitoring and integration into active surveillance systems (e.g., CDC's VSD) improve efficiency and accuracy. Challenges include ensuring interpretability, managing false alarms, and adapting to evolving drug safety profiles.
Explainable AI & Regulatory Compliance
Explainable AI (XAI) is crucial for trust and transparency in PV, addressing regulatory demands for clear justifications and bias mitigation.
XAI methods like LIME and SHAP identify important features in PV models, improving transparency and stakeholder understanding. These methods predict adverse outcomes with up to 72% accuracy while explaining feature contributions. However, challenges include feature collinearity and the complexity of deep learning models. Regulatory bodies (FDA, EMA) are developing frameworks for AI in PV, emphasizing transparency, reproducibility, and human oversight. Organizations like UMC use ML (vigiMatch, vigiRank) for routine PV tasks, demonstrating targeted AI applications while maintaining interpretability and addressing economic sustainability.

UMC's VigiMatch & VigiRank
The Uppsala Monitoring Centre (UMC), which manages the WHO global database of ICSRs (VigiBase), has implemented notable machine learning tools to enhance PV processes. Their vigiMatch algorithm represents one of the earliest applications of machine learning in routine PV, efficiently detecting duplicate case reports by processing approximately 50 million report pairs per second. In use since 2014, vigiMatch employs probabilistic methods to identify potential duplicate reports, addressing a significant challenge where even a small number of duplicates can trigger false safety signals. UMC has also developed vigiRank, which enhances signal detection by incorporating multiple evidence aspects beyond traditional disproportionality analysis, demonstrating how targeted AI applications can improve core PV functions while maintaining transparency and interpretability.
Key Takeaway: AI-powered tools can significantly enhance the efficiency and accuracy of core PV functions like duplicate detection and signal assessment, improving overall patient safety.
