Area of Science:

  • Pharmacovigilance
  • Regulatory Science
  • Health Informatics

Background:

  • Adverse event surveillance is critical for monitoring marketed medical products.
  • Existing surveillance processes required modernization to leverage technological advancements.

Purpose of the Study:

  • To redesign the post-marketing adverse reaction surveillance process at the FDA's Center for Drug Evaluation and Research.
  • To implement a new strategy for reviewing and analyzing adverse event reports efficiently.

Main Methods:

  • Developed a five-tier signal detection strategy for adverse event reports.
  • Incorporated automated review, context matrices, graphical displays, and active query capabilities.
  • Migrated historical data and coded all data using the Medical Dictionary for Regulatory Activities (MedDRA) scheme.
