Impact of Particulate Matter in Chronic Obstructive Pulmonary Disease Patients

Not Applicable

• Conditions: COPD
• Interventions: Behavioral: Education about particulate matter practice score

• Registration Number: NCT04020237
• Lead Sponsor: Sei Won Lee

Brief Summary

A prospective study will be conducted in patients with COPD. The investigators will suggest about intervention for preventing in recurrence and aggravation of adult chronic respiratory disease due to exposure to particulate matter.

Detailed Description

Study trends and intervention plans related to particulate matter exposure and adult chronic respiratory disease in literature Measurement of particulate matter exposure by individual activities and collection of clinical information Linkage between individual particulate matter exposure and clinical information Investigation about effectiveness of intervention to avoid particulate matter
