Efficacy of 8-week Supervision in Home Based Pulmonary Rehabilitation

Study Overview
=================
Brief Summary
-----------------
In korea, it is not easy to practice standard pulmonary rehabilitation (PR). in this study, we'll educate PR to patients and make reservation for re-visiting outpatients clinics with PR diary. we want to confirm whether patients, who perform home based PR during more than 30 minutes in 3 days per week, present improved dyspnea score or quality of life compared with non-compliance group.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Behavioral: Pulmonary rehabilitation|In this study, we'll educate pulmonary rehabilitation to patients and make reservation for re-visiting outpatients clinics with PR diary after 8 weeks. we want to confirm whether patients, who perform home based PR during more than 30 minutes in 3 days per week, present improved dyspnea score or quality of life compared with non-compliance group.|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from basline Chronic obstructive pulmonary disease (COPD) assessment Test (CAT) at 8 weeks | Self reported Patient-completed questionnaire assessing globally the impact of COPD (cough, sputum, dyspnea, chest tightness) on health status. Each item is scored 0-5, yielding a total between 0 and 40 | 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| change from 6 minutes walk test at 8 weeks | This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes (the 6MWD). | 8 weeks | 
| Change from the Short Form 36 Health survey (SF-36), version 2.0 at 8 weeks | a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability. | 8 weeks | 
| Change from BODE index at 8 weeks | BODE index include forced expiratory volume-one second, 6 minutes walk distance, modified Medical Research Council dyspnea scale, body mass index. The BODE Index is used to predict mortality. | 8 weeks |
