- Abstract
- Short-acting 82-agonist (SABA) use is known to be lower in Korean patients with asthma than in those from other countries, while the rate of asthma exacerbations in Korea is higher than in other countries. Thus, an epidemiologic study on SABA use and the relationship between SABA overuse and treatment outcomes in asthma is needed in Korea. We performed a crosssectional study using the National Health Insurance Service-National Sample Cohort 2002-2012 database. We evaluated the trend of annual SABA use and overuse (prescription of 3 or more SABA canisters/year) and the impact of SABA overuse on mortality. During the study period, the proportion of asthmatic patients who used SABA was approximately 8%-11%, with no significant change in trend. The mean annual SABA use in asthmatic patients was 0.15-0.22 canisters/patient/year and 1.93-2.05 canisters/patient/year in those who used SABA in 12 months. SABA overuse was observed in about 2%-4% of asthmatic patients during the study period. SABA overuse generally tended to increase as the age of patients increased, with triple peaks in the late 20s (3.3%), late 40s (3.1%), and late 70s (3.6%). SABA overuse was associated with mortality (adjusted odds ratio, 1.72; 95% confidence interval, 1.61-1.84). The rate of SABA use was very low in Korean asthmatic patients between 2002-2012. SABA overuse was found in 2%-4% of patients in Korea. SABA overuse was associated with an increased risk of mortality.
