Previous studies on patients with mild COPD have focused on symptomatic patients. Therefore, in this study, we evaluated the treatment status of patients with early COPD in Korea.Materials and methods: We compared hospital visits, medical costs per person, and COPD medication use by patients with COPD screened from the general population and COPD cohort patients. Patients with COPD aged ≥40 years with the value of forced expiratory volume in 1 s (FEV1) ≥60% were selected from the 2007 to 2012 Korea National Health and Nutrition Examination Survey (KNHANES) data. Data including the number of outpatient clinic visits, admission to hospitals, COPD-related medications, and medical costs were obtained from the Health Insurance Review and Assessment Service and were compared with the data of patients with COPD with FEV1 ≥60% from the Korean COPD Subtype Study (KOCOSS) cohort.Results: Based on EuroQol 5-dimension questionnaire index scores of 0.9±0.14, we found that patients with COPD from the KNHANES group showed few symptoms compared to those from the KOCOSS cohort. In 2007, among the patients with COPD with an FEV1 value of ≥60%, only 3.6% from the KNHANES group and 30% from the KOCOSS cohort visited medical facilities. Total medical cost per person per year increased from 264.37±663.41 US Dollars (USD) in 2007 to 797.00±2,724.21 USD in 2012 for the KNHANES group. In 2012, only 20.7% of the patients from KNHANES database received long-acting muscarinic agonists (LAMA), whereas 78.7% of the patients from KOCOSS database received LAMA.Conclusion: Medical resource utilization and medical costs per person for patients with early COPD in Korea increased. However, asymptomatic patients with COPD represented by the KNHANES group do not receive adequate long-term treatment compared to relatively symptomatic patients, and require more clinical attention from physicians.
