Despite clinical benefits of long-acting muscarinic antagonist (LAMA)/long-acting beta2-agonist (LABA) double bronchodilator therapy, there has been limited evidence for treatment change from LAMA/LABA to inhaled corticosteroid (ICS)-containing therapy. This study aimed to assess the rate of ICS-containing therapy from LAMA/LABA and investigate the factors associated with ICS addition. Between October 2015 and March 2019, consecutive patients prescribed with a LAMA/LABA fixed-dose combinations (FDCs) therapy without ICS were retrospectively identified from a single-referral hospital. The primary outcome was addition of ICS. During LAMA/LABA FDCs therapy (median, 12.4 months), 47 (17.7%) out of 266 patients had ICS addition. Most patients maintained bronchodilators without addition of ICS at 12 (86.5%) or 24 (76.8%) months. Patients with dyspnea (mMRC ≥ 2) at baseline, previous ICS use, and exacerbation in the previous year were at a higher risk of ICS addition. Especially, exacerbation in the previous year and dyspnea were associated with the development of frequent exacerbations during LAMA/LABA FDCs therapy, which might have led to ICS addition. Double bronchodilator therapy could be well-maintained in stable COPD patients. However, patients with exacerbation in the previous year, dyspnea, and previous ICS use should be closely approached and monitored with initiation of LAMA/LABA FDCs therapy without ICS.
