AI in Pharmacovigilance Case Intake: Not a Silver Bullet

by: Upendra Shukla

Introduction

While Artificial Intelligence (AI) promises transformative efficiency in various fields, its role in pharmacovigilance (PV) case intake—the process of collecting and processing adverse drug event reports—comes with significant limitations. Many pharmaceutical companies are now overcoming the initial hesitation and starting to rely on automation to streamline PV case management.
With the advent of so many AI models and products mushrooming around these models begs this analysis – are AI-based solutions really the silver bullet to case intake automation? AI/ML models present a very interesting proposition for use in various use cases, such as extracting ADRs, skimming through literature documents, and early signal detection. The use of AI allows large volumes of data to be processed in much less time, and it provides humans with insights and time to focus on more important aspects of the PV lifecycle. However, purely AI-based solutions often introduce challenges such as inconsistent outputs, data gaps, and poor scalability.

Why AI Alone Falls Short for Case Intake Automation

Generative AI and Large Language Models (LLMs) represent two highly dynamic and captivating domains within the field of artificial intelligence. They have left the traditional AI models far behind in terms of capabilities and accuracy in performing generic tasks. Generative AI is a comprehensive field encompassing a wide array of AI systems dedicated to producing fresh and innovative content, spanning text, images, music, and code. In contrast, LLMs constitute a specific category of generative AI models, which are trained on vast amounts of text-based data to generate human-like textual output. From a suitability perspective, LLM would be more suitable for feeding an abstract or unstructured text for it to identify and generate ADRs, and other AE data
AI-based solutions for pharmacovigilance struggle with certain inherent limitations:
1. Inconsistent Outputs: Even when the same model is fed identical inputs, AI solutions can generate varied results. This happens due to model dependencies on probabilistic algorithms, context interpretation, or slight changes in how text is parsed.
2. Data Completeness Issues: AI models are often trained on historical data, making them vulnerable to missing or misinterpreting critical information in new contexts, such as non-standardized adverse event reports or abbreviations used in clinical data.
3. Handling Complex Inputs: Adverse event data comes from a variety of sources, including free text in emails, structured forms, and scanned documents. AI models often struggle to extract reliable information from such diverse input formats with precision.
4. Lack of Control and Transparency: AI solutions can behave like a "black box," where it’s unclear how decisions are made. Regulatory standards in the pharmaceutical industry require transparency for auditing and compliance, a need AI-only tools can fail to meet.
These challenges collectively hinder the ability of pharmaceutical companies to consistently meet compliance targets and ensure reliable drug safety reporting. Thus leading to the reluctance of several other companies to adopt automation solutions altogether. Modern-day AI models are much like young children who need to be closely watched, guided at every step of the way, and their outputs constantly reviewed before being used for regulatory reporting purposes.
However, what if there was a way to overcome the limitation of AI and instead use it effectively to augment the abilities of an already robust solution? This is where the NOESIS platform comes into play. Drogevate’s NOESIS Platform addresses these pitfalls by combining AI with proprietary algorithms, delivering consistent and accurate case intake that far outperforms typical AI-only approaches. NOESIS adopts a Human-in-command approach where all the data flowing out of the system is duly controlled by humans on top of the system.

NOESIS Platform: A Hybrid Approach by Drogevate

The NOESIS platform by Drogevate bridges the gap by integrating AI models with definitive proprietary algorithms. This blend ensures that data extraction is not only automated but accurate and reproducible, mitigating the inconsistencies typical of AI-only solutions.
Key Features of the NOESIS Platform
  • Proprietary Rules-Based Processing: NOESIS applies pre-defined business rules to extract data, ensuring a consistent structure regardless of input variations. This proprietary logic is tailored for pharmacovigilance needs, including handling E2B reports and clinical safety documents.
  • AI-Augmented with Validation Layers: AI models support but do not solely determine the final output. NOESIS applies multiple additional layers to cross-check results, ensuring accurate and complete extraction of case data.
  • Adaptability to Different Input Formats: NOESIS can handle inputs from PDF forms, scanned images, Excel & Word documents and emails while maintaining high extraction accuracy. This adaptability ensures that adverse event reports from varied sources are captured correctly.
  • Consistent Outputs: The system ensures that the same input always yields the same output, in contrast to fluctuating AI-only solutions. This consistency is very important for business teams and decision-makers in adopting a solution for automation.
  • Human Control: The configurability of the NOESIS platform puts the humans manging the system in the driver’s seat and in full control of the PV data. This is very important from a regulatory perspective.
  • Scalable: NOESIS offers reliable performance even with high-volume workloads, making it suitable for global pharmacovigilance operations. NOESIS is carved out of a true cloud architecture which ensures automated rule-based scalability as per varying workloads.
  • Cost Effective: The costs with NOESIS platform do not spiral out of control with increasing volumes, rather they diminish due to economies of scale coming into play. Even though cost may not be the primary consideration for many of the pharma companies looking for automation solutions, but it is an important one.

Overcoming the Challenges: Real-World Applications

The NOESIS Platform has already been successfully deployed across multiple customers (pharmaceutical organisations and contract research organisations) for pharmacovigilance process automation. The platform’s adaptability allows companies to quickly adjust business rules for new regulatory changes without overhauling the AI models, a critical advantage over AI-only tools.
According to industry reports, companies that rely solely on AI for adverse event intake often face IT-related challenges, including system validation and infrastructure limitations. Drogevate’s hybrid solution not only addresses these barriers but also provides a faster return on investment by reducing manual effort and ensuring compliance with minimal human intervention.

Conclusion

AI in pharmacovigilance is not a silver bullet. While AI provides valuable automation benefits, relying solely on AI models for case intake introduces risks such as inconsistent outputs and incomplete data extraction. Drogevate’s NOESIS Platform offers a hybrid approach that blends AI with proprietary rules-based logic, ensuring accurate, consistent, and reliable data intake every time. This solution enables pharmaceutical companies to scale operations efficiently while maintaining the highest levels of compliance and transparency.
