만성 폐쇄성 폐질환 COPD

상세 설명

This is a multi-centre, prospective, observational study. This study aims to observe the general situation in clinical practice, and the evolution and outcome of current usual care of COPD in China.This is an observational study. It will be carried out under routine clinical practice and the treatment will be determined by patients' treating physicians. Information about exposure to treatments as part of routine care will be collected (dose, frequency and duration).

A multi-stage, stratified and cluster sampling method will be used to select a nationally representative sample from the tertiary and secondary hospitals with respiratory department in six geographic regions around China as the study sites. Approximately 5000 patients with COPD will be enrolled from 50 selected study sites in order to recruit a nationally representative study population and followed up for one year.

The distribution of different severity of COPD exacerbations 기간: within one year	The distribution will be measured by percentage of patient on each level of severity of COPD exacerbations (mild: requiring an increase in rescue medication≥ 3 puffs / day for at least 2 consecutive days; moderate: requiring systemic glucocorticosteroids and/or antibiotics; severe: hospitalization, emergency room visit or leading to death), the calculation will be based on non-missing data.	within one year
The mean reduction value of available FEV1 기간: within one year	The mean reduction value of available FEV1 after one year from baseline	within one year
The mean change in CAT 기간: within one year	The mean change in CAT total scores after one year from baseline; COPD assessment test (CAT) total score will be derived by summing up the score of all items. Total Scores range 0-40.The COPD influence on patients: 1 stage (mild): 0-10 points; 2 stage (moderate): 11-20 points; 3 stage (severe):21-30 points; 4 stage (very severe):31-40 points.	within one year
