Impact of Particulate Matter in Chronic Obstructive Pulmonary Disease Patients

Study Overview
=================
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

Official Title
-----------------
Evaluation of Quality of Life in Patients With Chronic Pulmonary Obstructive Disease According to Particular Matter Exposure

Conditions
-----------------
COPD

Intervention / Treatment
-----------------
* Behavioral: Education about particulate matter practice score

Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Observational arm<br>General counselling to particulate matter practice score. | |
| Other: Interventional arm<br>Active education and feedback on the particulate matter practice score that affects real life. | Behavioral: Education about particulate matter practice score<br>* For the intervention group, specific guidance is given to the patient who might be exposure in environment with higher particulate matter concentration. 1) Start air purifier 2) Do not go out and make it to the minimum when absolutely necessary 3) It is recommended to wear a mask when going out. 4) The investigators recommend a lot of water, fresh fruit and vegetables. 5) Prepare an inhaler and use it when symptoms get worse.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Chage from life quality scale at 1 year | Via average of total chronic obstructive pulmonary disease assessment test (CAT) score (total range 0-40, higher score means bad outcome, CAT score consisted of summed score about cough (0-5), phlegm (0-5), chest tightness (0-5), breathlessness (0-5), activites (0-5), confidence (0-5), sleep (0-5), energy (0-5)) | Up to 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from pulmonary function test at 1 year | Forced Expiratory Volume at 1 second level | Up to 1 year |
