Observational Study of Adherence to LABA / LAMA in Chronic Obstructive Pulmonary Disease (COPD)

Study Overview
=================
Brief Summary
-----------------
The objective of the study is to observe the effect of adherence to once-daily administered long-acting bronchodilators (long-acting ß2-agonists [LABAs] / long-acting muscarinic antagonists [LAMAs]) on patients health related quality of life (HR-QoL) and to assess the relation between symptoms improvement and adherence to Chronic Obstructive Pulmonary Disease (COPD) maintenance therapy

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical COPD Questionnaire (CCQ) Total Score Change From Baseline at Month 13 | The Clinical COPD (Chronic Obstructive Pulmonary Disease) Questionnaire (CCQ) is a standardized, validated and reliable questionnaire (in local language) to assess the impact of treatment on health status in COPD patients. CCQ total score is calculated as the arithmetic average of 10 individual scores on a 7-point scale. CCQ total score varies from 0 (very good control) to 6 (extremely poor control). Mean change in CCQ total score from baseline at month 13 is presented along with its standard error. Change in CCQ total score is calculated for each subject as: CCQ total score at month 13 - CCQ total score at baseline. Baseline is defined as the first assessment after enrolment (at Month 1). | Baseline and 13 Month | 
| CCQ Total Score at Month 13 (Visit 4) | Mean and standard deviation of CCQ total score is presented at month 13. | 13 months | 
| Number of COPD Exacerbations Leading to Hospitalization, Per Patient | Percentage of subjects hospitalized due to COPD exacerbations exactly n number of times during the study period is presented. Here, n represents the number of times each subject is hospitalized due to COPD exacerbations. | 13 months | 
| Number of COPD Exacerbations, Per Patient | Percentage of subjects experienced COPD exacerbations exactly n number of times during the study period is presented. Here, n represents the number of times each subject experienced COPD exacerbations. | 13 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reasons of Non-adherence to Once-daily Long-acting Bronchodilators in COPD Patients | Percentage of subjects corresponding to each reason of non-adherence to once-daily long-acting bronchodilators in COPD patients are presented. | 13 months |
