However, the association between GORD and the disease burden of bronchiectasis has not been well evaluated. Our study aimed to evaluate whether GORD is associated with increased healthcare use and medical costs in patients with bronchiectasis. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p> We analyzed the data from 44,119 patients with bronchiectasis using a large representative Korean population-based claim database between 2009 and 2017. We compared the healthcare use [outpatient department (OPD) visits and emergency room (ER) visits\/hospitalizations] and medical costs in patients with bronchiectasis according to the presence or absence of GORD. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> The prevalence of GORD in patients with bronchiectasis tended to increase during the study period, especially in the 50s and older population. GORD was associated with increased use of all investigated healthcare resources in patients with bronchiectasis. Healthcare use including OPD visits (mean 47.6\/person\/year versus 30.0\/person\/year), ER visits\/hospitalizations (mean 1.7\/person\/year versus 1.1\/person\/year), and medical costs (mean 3564.5 Euro\/person\/year versus 2198.7 Euro\/person\/year) were significantly higher in bronchiectasis patients with GORD than in those without GORD ( p &lt; 0.001 for all). In multivariable analysis, bronchiectasis patients with GORD showed 1.44-fold (95% confidence interval = 1.37\u20131.50) and 1.26-fold (95% confidence interval = 1.19\u20131.33) increased all-cause and respiratory-related ER visits\/hospitalizations relative to those without GORD, respectively. After adjusting for potential confounders, the estimated total medical costs (mean 4337.3 versus 3397.4 Euro\/person\/year) and respiratory disease-related medical costs (mean 920.7 versus 720.2 Euro\/person\/year) were significantly higher in bronchiectasis patients with GORD than in those without GORD ( p &lt; 0.001 for both). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> In patients with bronchiectasis, GORD was associated with increased healthcare use and medical costs.
