Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed as a multicenter, prospective and retrospective and descriptive epidemiology study.

This study is planned to evaluate 2 years of exacerbation in COPD patients and to investigate correlation of COPD disease progress and its exacerbation.

This study is designed with 6 months of subject enrollments, 12 months of retrospective study, and 12 months of prospective study. Hence, each patient will be participating in the study for 12 months, while the actual data collections from the patients will take a total of 24 months.

The statistical analysis of this study will be done twice, at the completion of 1 year retrospective data collection and at the completion of next 1 year follow-up.

The 1st statistical analysis of retrospective study includes exacerbation rate, duration of hospitalization for exacerbation and lung function test for the past 1 year from the enrollment and comorbidities, COPD assessment (CAT) and COPD medication at the enrollment will be analyzed.

The 2nd statistical analysis of prospective 1-year follow-up includes changes in exacerbation rates, comparison of lung function test results, comorbidities, COPD assessments (CAT) and COPD medications of retrospective and prospective studies for the 2 years as well as mortality rate.
