초록

This study was conducted to investigate overall systemic antibiotic consumption levels and specific patterns using standardized Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) methodology. National Health Insurance claims data during 2008 and 2009 was used. Antibiotic prescription data was classified using the ATC system and converted into DDD. Consumption figures were presented as the number of DDD per 1,000 inhabitants per day (DID). Detailed information on indications and seasonal variations, age and institutional determinants on antibiotic consumption were also explored. Total consumption was slightly increased from 24.3 to 25.2 DID in 2009 compared to 2008. The most frequently prescribed antibiotic was amoxicillin/clavulanic acid (5.1 and 5.2 DID, in 2008 and 2009, respectively), followed by cefaclor (3.0 and 3.3 DID) and amoxicillin (3.3 and 3.2 DID). Respiratory system diseases were the main causes of antimicrobial prescription (47.3%) and acute forms of bronchitis, tonsillitis and sinusitis were the most common diseases. There were typical seasonal fluctuations with heightened winter peaks. Consumption figures under 5 years of age (41.6 and 43.3 DID) were even higher than figures in aged 65 - 80 (36.2 and 39.1 DID). Antibiotic consumption in South Korea remained high compared with other OECD countries. Efforts to increase prudent antibiotic use, especially for upper respiratory system infections and for younger children, should be made to decrease antibiotic use.
