Coding: The Mortar in the Bricks of Data Analysis

Abstract

This discussion gives a broad overview of CODING, as it pertains to the storage and analysis of adverse events in clinical or spontaneous databases. It also offers a brief look at the larger perspective of the uses of medical terminology, and taxonomies in general. Although similarities in purpose exist across many different coding systems in use in the pharmaceutical industry, many problems are encountered when cross-comparisons are attempted. Some of these problems are also addressed. Finally, the discussion focuses on some of the technical, financial, and organizational issues faced by persons involved with the development and upkeep of their respective coding systems. Coding is usually a very low-visibility process, but its accuracy and quality are absolutely essential if we are to evaluate medical data in meaningful aggregates.
