Socioeconomic Burden of Disease Due to Asthma in South Korea

This study aimed to estimate the socioeconomic burden of asthma in South Korea. The data were obtained from the National Patient Sample of 2014. The direct costs included health care and non–health care costs, and the indirect costs included loss of productivity. To estimate the prevalence of asthma, this study used both primary diagnoses and treatment-based criteria. The prevalence of asthma was 3.7% using primary diagnosis-based criteria. The total costs of asthma were $645.8 million. The direct and indirect costs were $553.9 million and $92.0 million, respectively. When the treatment-based criteria were applied, the prevalence decreased to 1.8% and the total costs decreased to $465.1 million. The direct and indirect costs were $394.9 million and $70.2 million, respectively. In the future, the cost of asthma, derived from various perspectives, should be regularly estimated and used as a basis for lowering the burden of disease due to asthma.
