Introduction: We aimed to determine in-hospital outcomes, length of hospital stay (LOS) and resource utilization in a contemporary cohort of patients with inflammatory bowel disease (IBD) and atrial fibrillation (AFIB).

Material and methods: The National Inpatient Sample database October 2015 to December 2017 was utilized for data analysis using the International Classification of Diseases, Tenth Revision codes to identify the patients with the principal diagnosis of IBD.

Results: Of 714,863 IBD patients, 64,599 had a diagnosis of both IBD and AFIB. We found that IBD patients with AFIB had a greater incidence of in-hospital mortality (OR = 1.3; 95% CI: 1.1-1.4), sepsis (OR = 1.2; 95% CI: 1.1-1.3), mechanical ventilation (OR = 1.2; 95% CI: 1.1-1.5), shock requiring vasopressor (OR = 1.4; 95% CI: 1.1-1.9), lower gastrointestinal bleeding (LGIB) (OR = 1.09, 95% CI: 1.04-1.1), and hemorrhage requiring blood transfusion (OR = 1.2, 95% CI: 1.17-1.37). Mean LOS ± SD, mean total charges and total costs were higher in patients with IBD and AFIB.

Conclusions: In this study, IBD with AFIB was associated with increased in-hospital mortality and morbidity, mean LOS and resource utilization.
