Outcome Measures

Primary Outcomes (4)

  • the frequency of severe AECOPD

    To estimate the frequency of severe AECOPD, in a COPD population

    10-year

  • time trends in the frequency of severe exacerbations

    To describe any time trends in the frequency of severe exacerbations throughout the study period (over a 2-year period)

    2-year

  • lung function decline over time

    To describe lung function decline over time (FEV1)

    3-year

  • health care resource utilization

    To quantify health care resource utilization by number of severe AECOPD over a 2-year period

    2-year

Interventions

A severe exacerbation will be primarily defined as a hospitalization (with or without ICU) or an emergency department visit as a result of worsening of COPD symptoms.

Sampling MethodNon-Probability Sample
Study Population

This study was based on the Korea COPD Subgroup Study (KOCOSS) database, constructed from a nationwide prospective cohort study-initiated in April 2012-that involved 54 medical centers in South Korea. It was designed to evaluate characteristics of COPD patients in South Korea.

You may qualify if:

  • Over 40 years old South Korean COPD patients(Bronchodilator test results FEV1/FVC \<0.7)
  • COPD patients who complain of cough, sputum, dyspnea
  • Unrelated smoking history

You may not qualify if:

  • other disease like asthma patients which is similar to COPD symptoms.
  • patients who is not suitable for pulmonary function test and communication
  • myocardial infarction or cerebrovascular event within the previous 3 months
  • pregnants
  • patients who disagree with registration
  • rheumatoid patients
  • cancer patients(including metastatic cancer, leukemia, lymphoma)
  • irritable bowel syndrome
  • patients who use systemic steroids over 8 weeks due to other diseases except COPD
