The Burden of Hospital Readmissions among Pediatric Patients with Inflammatory Bowel Disease.

OBJECTIVE: To evaluate the burden and predictors of hospital readmissions among pediatric patients with inflammatory bowel disease using the Nationwide Readmissions Database.

STUDY DESIGN: We performed a retrospective cohort study using 2013 Nationwide Readmissions Database. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify patients <18 years with diagnoses of ulcerative colitis (UC) or Crohn's disease (CD). Demographic factors and details of hospitalizations were evaluated using survey procedures in SAS v 9.4 (SAS Institute, Cary, North Carolina). Multivariable logistic regression was used to estimate ORs and 95% CIs of readmission.

RESULTS: Among 2733 hospitalizations (63% CD, 37% UC), 611 (22%) patients were readmitted within 90 days of the index hospitalization. Readmission resulted in weighted estimates of 11 440 excess days of hospitalization and total charges of over $107 million. For CD, male sex (aOR 1.36, 95% CI 1.03-1.81) and co-existing anxiety or depression (aOR 1.89, 95% CI 1.06-3.40) were associated with increased readmissions, while patients who underwent surgery had decreased readmissions (aOR 0.40, 95% CI 0.24-0.65). In patients with UC, an index admission of >7 days was associated with increased readmissions (aOR 1.69, 95% CI 1.09-2.62).

CONCLUSIONS: Readmission occurs frequently in children with inflammatory bowel disease and is associated with significant cost and resource burdens. Among patients with CD, psychiatric comorbidities such as anxiety and depression are apparent drivers of readmission.
