About

The KOrea COpd Subgroup Study team (KOCOSS) cohort is an ongoing, longitudinal, prospective, non-interventional and observational study within the Korean COPD patients. The prevalence of early COPD (mild to moderate COPD based by 2011 GOLD(the Global Initiative for Chronic Obstructive Lung Disease) guideline) is high in Korea. However, the patients with early COPD are not underdiagnosed due to mild symptom. The purpose of this study is to investigate early COPD characteristics and disease course and to form a guideline for early detection of COPD patients and prevention of progression to severe COPD.

Full description

This study is a multicentered, observational study of the patients with COPD who were enrolled in 45 tertiary and university-affiliated hospitals from December 2012 to now.

The initial evaluation for all patients includes pulmonary function tests (PFT), 6-min walk distance (6MWD), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C), exacerbations in the previous 12 months, smoking status, patient-reported education level, medications and comorbidities.

Pulmonary function tests (PFTs) are performed every 6 months and CAT, mMRC and SGRQ-C are evaluated every 6 months and 6 min walt test is performed every years during the whole period of study.

All of the data were reported using case-report forms (CRFs) which are completed by physicians or trained nurses, and the patients are to be evaluated at regular 6-month intervals after the initial examination.
