OBJECTIVES: Hospital care accounts for up to one-third of the cost of inflammatory bowel disease (IBD) management. A select group of patients with IBD is responsible for a large proportion of this utilization, demonstrating the burden of frequent hospitalizations. We aim to better understand the burden of 30-day readmissions among patients with IBD using a national hospital database. STUDY DESIGN: Retrospective cohort study of state-specific inpatient databases. METHODS: The State Inpatient Databases for New York and Florida were used to identify patients with IBD hospitalized between 2009 and 2013. The prevalence of 30-day IBD-specific readmission was determined. The association between 30-day readmission and visit outcomes, specifically length of stay and a composite of comorbid conditions (venous thromboembolism, pneumonia, sepsis, Clostridium difficile infection, enteral and parenteral nutrition, and blood transfusion), was analyzed using multivariable logistic regression. RESULTS: Patients with IBD accounted for 35,514 and 39,506 inpatient stays in New York and Florida, respectively. Of these stays, 13.7% to 16.2% resulted in a 30-day readmission. On multivariable analysis, 30-day readmissions were associated with a longer length of stay than index hospitalizations by 1.00 day (adjusted regression coefficient, 1.00; 95% CI, 0.73-1.26) and a higher likelihood of having a comorbid condition (adjusted odds ratio, 1.83; 95% CI, 1.68-1.99) in New York. Similar associations were confirmed in Florida. CONCLUSIONS: Nearly 1 in 7 hospitalizations of patients with IBD lead to a 30-day readmission. These IBD-specific readmissions are associated with increased utilization and comorbidity. Patients at risk for readmission need to be targeted to improve outcomes and IBD care quality.
