Conditions

COPD

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

Interventions

BEHAVIORALEducation about particulate matter practice score

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.

Design outcomes

Primary

MeasureTime frameDescription
Chage from life quality scale at 1 yearUp to 1 yearVia 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))

Secondary

MeasureTime frameDescription
Change from pulmonary function test at 1 yearUp to 1 yearForced Expiratory Volume at 1 second level
