In large clinical trials to date, bronchodilators have significantly improved respiratory function in patients with COPD, but patient-reported measures such as dyspnea and quality of life often fail to reach MCID (minimum clinically meaningful change), even though they are statistically significant. We feel that there is a discrepancy with the beneficial effects we experience in clinical practice. We hypothesized that this discrepancy may be due to the response shift phenomenon. We hypothesized that the standard axis for judging subjective indices such as dyspnea and QOL before and after bronchodilator treatment has changed, and that the difference is underestimated in a mere before/after comparison. We thought that this would allow us to evaluate the effect more accurately. We decided to reevaluate the pre-treatment status of COPD patients after treatment and compare it with the status originally assessed before treatment. In this study, we will evaluate respiratory function tests and the Japanese version of CAT (COPD Assessment Test), the Japanese version of SGRQ-C (COPD-specific St. George's Respiratory Questionnaire), and the Japanese version of SGRQ-C (COPD-specific Quality of Life Questionnaire) in COPD patients before and after treatment intervention.
