Brief Summary:
The objective of the study is to assess patient's perception with stable state COPD on symptom variability and to describe how symptom variability impacts daily quality of life in Chinese COPD patient with moderate, severe or very severe airflow limitation from tier 3 hospitals in China where most of COPD patients are diagnosed and treated.

Condition or disease
Chronic Obstructive Pulmonary Disease

Study Type : Observational
Actual Enrollment : 1058 participants
Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: Perception of Symptom Variability in Chinese COPD Patients
Study Start Date : December 2012
Primary Completion Date : November 2013
Study Completion Date : November 2013

Primary Outcome Measures :
  1. The variability of symptoms due to COPD throughout the day [ Time Frame: Day 1 ]
    • To ask subject, which symptoms(breathlessness, chest tightness, coughing, wheezing, phlegm)is COPD symptoms and exist throughout the day
    • To ask subject , whether COPD symptoms variability throughout the day exists or not ;
    • To ask subject , which (on waking, later in the morning, in the afternoon, in the evening, at night) is the most likely occurring time of these symptoms;
    • To ask subject , Which (on waking, later in the morning, in the afternoon, in the evening, at night) is the most troublesome time of these symptoms.

Secondary Outcome Measures :
  1. The impact of COPD symptoms on patient's daily living activities and sleep quality [ Time Frame: Day 1 ]
    • To ask subject, Whether essential daily activities affected by COPD symptoms and the type of following: going up and downstairs, Going out of shopping, doing sport/exercise, doing housework, or all of these
    • To ask subject, Whether sleep quality affected by COPD symptoms and the type of following: difficulty falling sleep, frequent waking during night, early waking in the morning, or all of these

  2. The impact of COPD symptoms on morning activities [ Time Frame: Day 1 ]
    • To ask subject, When [getting out of bed, dressing, washing, eating breakfast, morning activity after breakfast (indoor activity, including housework) , morning exercise (outdoor activity, such as walking, sport, etc)] the essential morning activities affected by COPD symptoms:
    • To ask subject, The extent of these morning activities affected: not at all, a little, moderate, severe, extremely severe resulting to feel difficult to complete independently, extremely severe resulting to complete under others help or cannot complete at all

  3. Total CAT score [ Time Frame: Day 1 ]
    CAT (COPD assessment test) has a broader coverage of the impact of COPD on the patient's daily life and well-being.

  4. Total MMRC score [ Time Frame: Day 1 ]
    MMRC (Modified Medical Research Council Questionnaire for Assessing the Severity of Breathlessness) assesses disability due to breathlessness.

  5. Patient's perception on COPD and COPD treatments [ Time Frame: Day 1 ]
    • To ask subject, Seek for treatment only when symptoms occur/worsening or regularly visit physician and take medicine(s)
    • To ask subject, Whether Knowing about how and when to use their medications
    • To ask subject, Usually taking their medication(s) required by physician to be used in the morning at what time: before getting out of bed, within 30 minutes after getting out of bed, within 30 minutes to 1 hour after getting out of bed, over 1 hour after getting out of bed, no regular time
