How CSL Behring Uses Natural Language Processing To Improve MedDRA Coding

Pages 3 Pages

Case study of CSL Behring’s effort to reduce manual coding of adverse events into MedDRA. Historically, only 30% of verbatim reports were autocoded; 70% required manual effort, particularly in rare disease cases. Partnering with IQVIA’s Linguamatics NLP platform, autocoding rose to 60% with minimal mismatches. In some cases, NLP-generated codes were more accurate than manual entries. The success prompted plans for a beta version with machine learning to further enhance pharmacovigilance.
