I. INTRODUCTION A. History of the ATC/DDD system The field of drug utilization research has attracted increasing interest since its infancy in the 1960s. The pioneering work was done by two consultants at the WHO Regional Office for Europe, Engel and Siderius (The consumption of drugs: report of a study 1966-1967. WHO regional Office for Europe, 1968). Their study of drug consumption in six European countries during the period 1966-1967 showed great differences in drug utilization between population groups. This study was followed by a symposium in Oslo in 1969 entitled The Consumption of Drugs, organised by the WHO Regional Office for Europe. It was agreed at this symposium that an internationally accepted classification system for drug consumption studies was needed. It was also at this symposium that the Drug Utilization Research Group (DURG) was established and tasked with the development of internationally applicable methods for drug utilization research. By modifying and extending the European Pharmaceutical Market Research Association (EphMRA) classification system, Norwegian researchers developed a system known as the Anatomical Therapeutic Chemical (ATC) classification. In order to measure drug use, it is important to have both a classification system and a unit of measurement. To deal with the objections against traditional units of measurement, a technical unit of measurement called the Defined Daily Dose (DDD) to be used in drug utilization studies was developed. The ATC/DDD system has been used in Norway since the early seventies for presenting drug consumption data. The Nordic Council on Medicines (NLN) established in 1975, collaborated with Norwegian researchers to further develop the ATC/DDD system. The NLN published the Nordic Statistics on Medicines using the ATC/DDD methodology for the first time in 1976. Since that time the ATC/DDD system has expanded to include most drugs on the Nordic market. At the same time, international interest in the ATC/DDD system for drug utilization research expanded beyond the Nordic countries largely through the activities of the DURG who recommended the ATC/DDD methodology for international drug utilization studies. 10
