Medical Coding Dictionaries and MedDRA

Medical coding dictionaries and MedDRA (Medical Dictionary for Regulatory Activities) are important tools used in Clinical Data Management Systems (CDMS) to standardize medical terminology and improve data quality.

Medical coding dictionaries are collections of standardized codes that are used to describe medical conditions, treatments, and procedures. The codes are used to accurately capture and classify medical information in a consistent and standardized manner. Medical coding dictionaries are widely used in the healthcare industry, including clinical trials, and provide a common language for healthcare providers and researchers.

MedDRA, specifically, is a widely-used medical coding dictionary developed by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH). MedDRA is used for standardizing the coding of medical terms and adverse events in clinical trials, and it is widely accepted by regulatory authorities worldwide. MedDRA helps to ensure that adverse event data is captured accurately, consistently, and in a standardized manner, which is essential for the evaluation and approval of new drugs.

The use of medical coding dictionaries and MedDRA in CDMS helps to improve data quality by ensuring that medical information is captured consistently and accurately, and it enables more meaningful analysis of the data.

MedDRA coding allows for categorisation of a term into multiple levels that include System Organ Class (SOC), Hight Level Group Terms (HLGT), High Level Terms (HLT), Preferred Term (PT) and Low Level Term (LLT).
