Abstract
BACKGROUND: Inflammatory bowel disease (IBD) - Crohn's disease (CD) and ulcerative colitis (UC) - are chronic inflammatory disorders of the intestine. Patients with IBD are at risk of hospitalization for disease exacerbation or IBD-associated complications. In the pediatric population, however, there are limited data on IBD hospitalizations. We therefore investigated the descriptive epidemiology of hospitalizations relevant to pediatric IBD. METHODS: The national inpatient claims database in Japan was searched for children (≤ 18 years old) with a diagnosis of IBD. The study period was 2007-2010. Data on demographic characteristics and descriptive statistics of the hospital course were extracted and analyzed. RESULTS: A total of 3559 admissions of 2175 patients met the definition of pediatric IBD: there were 1999 admissions for CD and 1560 admissions for UC. Internists were responsible for patient care in 56.6% of admissions, followed by pediatricians (27.5%). Of 3559 admissions, unscheduled hospitalizations accounted for 79.7%, and 7.6% of hospitalizations were attributable to complications of IBD, including intestinal, extraintestinal and other manifestations. The median age at first admission was 16 years (IQR, 13-17 years), in both the CD and UC groups. Compared with UC patients, CD patients had a higher number of hospitalizations (P < 0.001), but hospital stay was shorter (median: 6 vs 16 days, P < 0.001). There were seven fatal cases of IBD, accounting for 0.32% in the present series, and sepsis was the cause in five. CONCLUSIONS: This study provides a description of pediatric inpatients with IBD and their hospital course in Japan.
