Screening for High-risk Chronic Obstructive Pulmonary Disease

Screening Study at High-risk Chronic Obstructive Pulmonary Disease

This study is a multicenter cross-sectional study design aimed at screening risk factors for the combination of disease and syndrome in high-risk individuals with chronic obstructive pulmonary disease (COPD).

Targeting high-risk populations for chronic obstructive pulmonary disease (COPD), targeted at key issues such as unclear risk factors and lack of prevention and treatment plans, high-risk population screening was conducted to identify risk factors. This study is expected to detect at least 3600 high-risk individuals with early-stage chronic obstructive pulmonary disease. The incidence rate of high-risk individuals in the early stage of chronic obstructive pulmonary disease is 30%, which means the total screening population is 12000 cases.

Inclusion Criteria:

• According to the Diagnosis and Treatment Guidelines for Chronic Obstructive Pulmonary Disease (Revised in 2021), a multi-stage cluster random sampling method was used to select individuals from representative administrative villages with a history of chronic cough or sputum production, breathing difficulties, recurrent lower respiratory tract infections, and/or exposure to potential risk factors for chronic obstructive pulmonary disease.
• The investigators agreed to participate in this clinical study by voluntarily signing an informed consent form.

Exclusion Criteria:

• Patients who are delirious, have impaired consciousness, dementia, various psychiatric disorders, etc., and cannot be accurately informed of their basic physical condition.
• Patients who, in the opinion of the investigator, are not suitable for participation in this study.
