The association between inhaled long-acting bronchodilators and less in-hospital care in newly-diagnosed COPD patients.

Background: Although the efficacy of inhaled long-acting bronchodilators has been well documented in randomised controlled studies, whether similar effects are obtained in real-life clinical practice is not clear. In this study, we analysed the effect of inhaled long-acting bronchodilators in newly-diagnosed COPD patients.

Methods: The Korean Health Insurance Review and Assessment Service databases were used.
