Current Primary Outcome Measures (submitted: May 18, 2021)

• Percentage of Sputum Samples Positive for Bacterial Pathogens as Identified by Bacteriological Methods, in Any Stable COPD Patients and During AECOPDs [ Time Frame: Over the course of one year from the study start (Month 0 to Month 12) ]
  The proportion of sputum samples obtained at each visit (confirmed stable or AECOPD visits) and positive for specific bacterial pathogens by bacteriological methods (overall and by bacterial species). Numerator is the number of sputum samples positive for a given pathogen and denominator is the number of visits with a sputum sample tested for a given pathogen. Proportion is computed with 95% confidence intervals. A confirmed stable visit is defined as a scheduled study visit for which the investigator confirms that the subject is stable/ has recovered from a previous exacerbation. Bacterial pathogens include Haemophilus influenzae (Hi), Non-typeable Haemophilus influenzae (NTHi), non-Haemophilus influenzae (Non-Hi), Moraxella catarrhalis (M. catarrhalis), Streptococcus pneumoniae (S. pneumoniae), Staphylococcus aureus (S. aureus), Pseudomonas aeruginosa (P. aeruginosa), Klebsiella pneumoniae (K. pseumoniae), Acinetobacter baumannii (A. baumannii).
• Percentage of Sputum Samples Positive for Viral Pathogens as Identified by Polymerase Chain Reaction (PCR) in Stable COPD Patients and During AECOPDs [ Time Frame: Over the course of one year from the study start (Month 0 to Month 12) ]
  The proportion of sputum samples obtained at each visit (confirmed stable visits and AECOPD visits) and positive for specific viral pathogens by PCR (overall and by viral species). The numerator is the number of sputum samples positive for a given pathogen and the denominator is the number of visits with a sputum sample tested for a given pathogen. The proportion is calculated with 95% confidence intervals. Viral pathogens, as identified by PCR, include respiratory syncytial virus (RSV), parainfluenza virus, enterovirus, human rhinovirus (HRV), metapneumovirus, influenza virus, adenovirus, bocavirus and coronavirus.

Descriptive statistics (mean, standard deviation) on the CAT scores are tabulated at each stable visit. The CAT index is derived as the sum of the ratings recorded for each of the eight individual items.

Descriptive Information

• Brief Title: Occurrence of Potential Bacterial and Viral Pathogens in Stable Chronic Obstructive Pulmonary Disease and During Acute Exacerbations of the Disease, in Asia Pacific
• Official Title: Occurrence of Potential Bacterial and Viral Pathogens in Stable Chronic Obstructive Pulmonary Disease (COPD) and During Acute Exacerbations of COPD (AECOPD), in Asia Pacific
• Brief Summary: Since the infectious aetiology of AECOPD has been suggested to vary according to geographical region, the primary purpose of this study (which will be conducted in several countries in Asia Pacific) is to evaluate the occurrence of bacterial and viral pathogens in the sputum of stable COPD patients and at the time of AECOPD. Given the increasing and projected burden of COPD in the Asia Pacific region, this study will also evaluate the frequency, severity and duration of AECOPD, as well as the impact of AECOPD on health-related quality of life (HRQOL), healthcare utilisation and lung function.
