Antibiotic Consumption and Expenditures for Acute Upper Respiratory Tract Infections in Outpatients

This study aimed to quantify antibiotic consumption and expenditures for acute upper respiratory tract infec- tions (URIs) (J00-J06) in outpatients from 2009 to 2011. We used WHO ATC classification and DDDs in measuring antibiotic consumption. National Health Insurance and Medical Aid claims data were analyzed. Antibiotic consumption has decreased from 4.44 DDD/1,000inhabitants/day in 2009, to 4.43 in 2010 and 3.74 in 2011. The estimated expenditures were 8,206 won/ 1,000inhabitants/day in 2009, 8,379 in 2010, and 7,004 in 2011. Clinics accounted for 89.8% and 86.0% of antibiotic con- sumption and expenditures respectively for the acute URIs in 2011. We need to monitor antibiotic consumption consistently, and promote judicious antibiotic use.
