Interpretive Summary: Abdominal Pain Disorders such as irritable bowel syndrome affect approximately 10% of children and adults worldwide. In this study we evaluated changes in the rate of hospitalizations for these disorders in children. We found that hospitalizations for these disorders decreased coincident with the implementation of the Affordable Care Act.

Technical Abstract: The healthcare burden of pediatric functional gastrointestinal pain disorders (FGIDs) is unclear. Our study aimed to characterize the burden of these hospitalizations in the United States (US). We utilized the US National Inpatient Sample from 2002 to 2018 to capture pediatric hospitalizations (ages 4 to 18 years old) with a primary discharge diagnosis of abdominal pain, constipation, irritable bowel syndrome, dyspepsia, abdominal migraine, cyclic vomiting syndrome, or fecal incontinence. We calculated the FGID hospitalization prevalence rate, length of stay (LOS), and inflation-adjusted costs annually and assessed for statistically significant trend changes using joinpoint analyses. 22.3 million pediatric hospitalizations were captured, and 1 in 64 pediatric hospitalizations were attributed to a primary FGID hospitalization. The overall FGID hospitalization prevalence rate initially remained stable but decreased significantly from 2013 to 2018. Constipation and abdominal pain hospitalization rates, respectively, increased and decreased significantly over time. Constipation hospitalizations were more prevalent for younger non-Hispanic Blacks and Hispanics. FGID hospitalization rates stratified by sex were similar. Mean LOS was 2.3 days; average LOS increased significantly from 2002 to 2013 and then stabilized. FGID hospitalization costs averaged $6,216 per admission and increased significantly for all FGIDs except dyspepsia. Endoscopic procedures were the most common interventions. FGID hospitalization prevalence rates decreased recently, possibly due to national healthcare policy implementation. Nonetheless, constipation admissions increased. LOS was stable in recent years but associated costs-per-hospitalization were increasing over time, probably due to endoscopic procedures. More studies are needed to explain these prevalence and cost trends.
