China Chronic Obstructive Pulmonary Disease Registration Research

Henan University of Traditional Chinese Medicine3,012 enrolled

Overview

With the comparative effectiveness research methods and hospital registration study approach, the purpose of this study is to objectively record the methods, efficacy and its influencing factors of COPD commonly used treatment methods/programs (Western medicine, Traditional Chinese Medicine and Integrative Medicine) in the actual medical environment, analysis of application characteristics for the different programs, and provide the basis for its revision and promotion. It is a first registration study for COPD in China.

Chronic obstructive pulmonary disease (COPD) is a major disease of harm public health seriously. Although different treatment methods / programs (Western medicine, Traditional Chinese Medicine and Integrative Medicine) exist and are being developed to relieve symptoms and reduce mortality in COPD, most have only been studied in randomized controlled trials (RCT). Most RCT study patients usually require a single disease, the use of standard treatment and a single intervention to evaluate interventions in an ideal state can achieve maximum effect,that is theoretical effect, it is difficult to provide the evidence of practical clinical efficacy or effectiveness. Secondly, RCT often require strict inclusion and exclusion criteria, resulting in inadequate representation of the study, thus limiting its conclusions spread to overall. There are some challenges for different treatment methods on the actual effect of the patients in the evaluation of conventional medical practice with RCT. Real World Research based on clinical practice pay close attention highly in response to these problems, and the registry study had been applied widely in clinical practice. With the comparative effectiveness research methods and hospital registration study approach, based on the classes of medications recommended by 2014 GOLD and Chinese Treatment Guidelines for COPD, the purpose of this study is to objectively record the methods, efficacy and its influencing factors of COPD commonly used treatment methods/programs (Western medicine, Traditional Chinese Medicine and Integrative Medicine) in the actual medical environment, analysis of application characteristics for the different programs, and provide the basis for its revision and promotion. This is a first registration study for COPD in China.

Outcomes

Primary Outcomes

The frequency of exacerbation

Time frame: Change from Baseline in the frequency of exacerbation at the months 3, 6, 9, 12, 15, 18, 21 and 24.

Secondary Outcomes

all cause mortality

Time frame: through study completion, an average of 1 year

Forced expiratory volume in one second,FEV1

Time frame: Change from Baseline in the FEV1 at the months 6, 12, 18 and 24.

Dyspnea

Using modified british medical research council (mMRC) to assess the degree of dyspnea in patients with COPD, and how this changes over time.

Time frame: Change from Baseline in the mMRC at the months 3, 6, 9, 12, 15, 18, 21 and 24.

Symptoms

Using the COPD Assessment Test (CAT) as a comprehensive measure of symptoms.

Time frame: Change from Baseline in the CAT at the months 6, 12, 18 and 24.

Quality of life

Using the Chinese version of the 36-item Short Form Health Survey (SF-36) to measure quality of life.

Time frame: Change from Baseline in the SF-36 at the months 6, 12, 18 and 24.
