Clinical Outcome of Corticosteroids in the Treatment of Chronic Obstructive Pulmonary Disease(COPD) Exacerbations in China (CONTAIN Study): Post-hoc Analysis of the Database of Acute Exacerbation of COPD Non-interventional Study

This is a Post-hoc analysis based on the database of "A non-interventional, retrospective study on AECOPD treatment status in China". A large nation-wide retrospective non-interventional study has carried out from January to September 2014 in China. The study aimed to observe clinical practice including glucocorticoids treatment in AECOPD in China. The data for 5067 cases were collected. These cases met the following inclusion criteria: more than 40 years old, diagnosed by GOLD 2013 (GOLD: The Global Initiative for Chronic Obstructive Lung Disease) as COPD at least 3 months before AECOPD based on treating physician's judgment; the patients received hospitalization due to AECOPD since Sep 2013. Demographic information, administration of corticosteroids, medical and surgical history, comorbidities, clinical outcome, laboratory tests and lung function tests were recorded in database. There were 43 sites in the main study. These sites located in 22 provinces in China. A majority of sites (40 sites) were tier 3 hospitals in major cities. The data in study was provided by each site via medical records. In 5091 screening cases, 5067 cases were recruited and included in full analysis set (FAS). All cases in FAS will be included into this post-hoc analysis.

Through data mining and analysis, it is to explore the relationship between corticosteroids based treatment regimen and clinical outcome and the optimal treatment regimen for corticosteroids used in inpatients with COPD exacerbations based on our database.
