    Background/Aims: The prevalence of gastroesophageal reflux disease (GERD) has increased in Korea, and the economic burden of this chronic disease is substantial. We aim to investigate the treatment pattern and economic burden in Korea of refractory GERD requiring long-term use of proton pump inhibitors (PPIs). Methods: We conducted a cross-sectional analysis of nationally representative sample data obtained from 2012 to 2016 and provided by the Health Insurance Review and Assessment Service. The participants were 86 936 in the medication group and 40 in the surgery group. Age- and sex-standardized prevalence of refractory GERD requiring PPIs medication for more than 12 weeks were analyzed. Generalized linear models were used to estimate cost ratios for comparing the medical costs of the surgery and medication groups after adjustment for demographics and comorbidity. Results: The prevalence of refractory GERD increased from 1.2% in 2012 to 1.9% in 2016, and the estimated total number of GERD patients increased from 402 000 to 736 000 during this time period. The medical expenditures of the surgery group within 90 days of antireflux surgery (ARS) were 16.9-fold higher compared to those of the medication group; the significant difference in medical costs between the 2 groups disappeared after 90 days post-surgery. Conclusions: The prevalence of refractory GERD requiring long-term use of PPIs has been trending upwards recently. Nevertheless, ARS is very rarely performed. Considering the increasing medical costs of long-term PPI use, further cost-effectiveness analysis is needed to compare ARS and PPI therapy for the treatment of GERD in Korea.
