An Observational Registry of Chinese COPD Study

Study Overview
=================
Brief Summary
-----------------
This is a multi-center, observational registry study involving secondary and tertiary hospitals across China. The objective is to study the disease burden, disease progression, comorbidities, treatment pattern and real-world cost, effectiveness and safety of different therapy options for COPD patients in Chinese clinical practice in China.

Detailed Description
-----------------
COPD is the most common chronic respiratory disease in China and has caused significant economic and humanistic burden. Patient reported outcomes (PRO) have been widely used to assess disease activity and quality of life for COPD patients. Wearable devices enable recording activity data of patients continuously and automatically. The objective of the study is to study the disease burden, disease progression, comorbidities, treatment pattern and real-world cost, effectiveness and safety of different therapy options for COPD patients in Chinese clinical practice in China. This is a multi-center, observational registry study involving secondary and tertiary hospitals across China. 3000-5000 participants are planned to be recruited. Each participant will be followed-up at baseline and every 3 months. Clinical assessment data, laboratory examination data and cost data are captured from electronic medical records (EMR). Patient-reported outcome (PRO) data are collected via smartphone app. Part of patients will receive wearable devices to record digital health technology (DHT) data. As the first ever observational registry focused on COPD stable-period management, this study can provide more information on these following issues. (1) Annual changes in COPD prevalence, treatment pattern and economic burden in China. (2) Assessing the real-world effectiveness and safety of different treatment patterns of COPD via EMR, PRO and DHT. (3) Cost-effectiveness and budget impact to the public healthcare funds of different treatment patterns of COPD.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Characterize COPD Disease Severity in Clinical Practice | Pulmonary Function Test measured by protable spirometer can represent the severity stages of COPD | 2 years | 
| Characterize COPD Disease Activity in Clinical Practice | Acute exacerbation of symptoms can reflect the disease activity and disease control of COPD. | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluate Medical Expenditure in Clinical Practice | Medical expenditure for patients include inpatient cost, outpatient cost and emergency room cost. | 2 years | 
| Evaluate Patient Reported Outcome | COPD Assessment Test (CAT) is an 8-item, self-reported scale which can represent symptom and health status for COPD patients. | 2 years | 
| Evaluate Health Related Quality of Life | Euroqol-5 Dimension Questionnaire (EQ-5D) is an 5-item, self-reported scale which can measure health related quality of life. | 2 years | 
| Evaluate Digital Health Technology Outcome | Real-time monitoring of oxygen saturation (SpO2) is an objective manifestation of dyspnea. | 2 years |
