A knowledge management platform for documentation of case reports in pharmacovigilance

Area of Science:

• Pharmacovigilance
• Medical Informatics
• Drug Safety

Background:

• Existing drug adverse effect reporting systems lack standardized documentation guidance.
• Systematic reviews of adverse drug reactions require improved methodologies.

Purpose of the Study:

• To develop the VigiTermes platform for enhanced pharmacovigilance case report documentation.
• To improve the efficiency and transparency of safety signal investigations for pharmaceutical industry and regulatory authorities.

Main Methods:

• Developed a prototype platform integrating ITM, Luxid, and an academic web service.
• Implemented standardized search strategies and automated information extraction from Medline abstracts.
• Annotated retrieved literature for pharmacovigilance relevance.

Main Results:

• The system reduced the number of publications for review from 578 to 229.
• Achieved a 60% decrease in the time required for literature review.
• Demonstrated a recall rate of 70%, indicating a need for further development to improve exhaustivity.

Conclusions:

• The VigiTermes platform shows significant potential in improving the efficiency of systematic reviews for adverse drug reactions.
• Further development is necessary to enhance the comprehensiveness of the system's literature retrieval.
• The platform offers valuable tools for pharmacovigilance experts in assessing drug safety signals.
