Acute Pancreatitis Admission Trends: A National Estimate through the Kids' Inpatient Database.

OBJECTIVES: To evaluate national health care use and costs for pediatric acute pancreatitis.

STUDY DESIGN: The Kids' Inpatient Database for 2006, 2009, and 2012 was queried for patients with a principal diagnosis of acute pancreatitis. Cases were grouped by age: preschool (<5 years of age), school age (5-14 years of age), and adolescents (>14 years of age).

RESULTS: A total of 27 983 discharges for acute pancreatitis were found. The number of admissions increased with age: young n = 1279, middle n = 8012, and older n = 18 692. Duration of stay was highest in preschool children (median, 3.47 days; IQR, 2.01-7.35), compared with school age (median, 3.22 days; IQR, 1.81-5.63) and adolescents (median, 2.87 days; IQR, 1.61-4.81; P < .001). The median cost of hospitalization varied with age: $6726 for preschoolers, $5400 for school-aged children, and $5889 for adolescents (P < .001). Acute pancreatitis-associated diagnoses varied by age. The presence of gallstone pancreatitis, alcohol, and hypertriglyceridemia was more common among older children compared with younger children (P < .001). There was an increasing trend in acute pancreatitis, chronic pancreatitis, and obesity for the 2 older age groups (P < .001).

CONCLUSION: Admission of children for acute pancreatitis constitutes a significant healthcare burden, with a rising number of admissions with age. However, the cost and duration of stay per admission are highest in young children.
