Abstract: Abstract Background Few studies have addressed recent trends in hospitalization costs for inflammatory bowel disease (IBD). Objective We explored trends and described patient and hospital factors associated with hospitalization costs for IBD. Methods Using data from the 2003–2014 National Inpatient Sample for adults aged ≥ 18 years, we estimated costs using multivariable linear models and assessed linear trends by time periods using piecewise linear regressions. Results In 2014, there were an estimated 56,290 hospitalizations for Crohn’s disease (CD), with a mean cost of US$11,345 and median cost of US$7592; and 33,585 hospitalizations for ulcerative colitis (UC), with a mean cost of US$13,412 and median cost of US$8873. Higher costs were observed among Hispanic [adjusted cost ratio (ACR) = 1.07; 95% confidence interval (CI) = 1.00–1.14; p = 0.04] or other non-Hispanic (ACR = 1.09; 95% CI = 1.02–1.17; p = 0.01) CD patients than for non-Hispanic White CD patients. For UC patients, higher costs were observed among men (ACR = 1.09; 95% CI = 1.05–1.13; p
