Nationwide Evolution of Pediatric Endoscopic Retrograde Cholangiopancreatography Indications, Utilization, and Readmissions over Time

To analyze outcome and utilization trends over time of pediatric endoscopic retrograde cholangiopancreatography (ERCP) in an all-capture US population-level study.Using the National Inpatient Sample (2005-2014) and National Readmission Database (2010-2014), we identified pediatric (age20 years) hospitalizations during which ERCP was performed and assessed ERCP-associated readmissions. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify hospitalization diagnoses, comorbidities, and patient/hospital characteristics. Multivariate logistic regression analyses were performed to determine significant predictors (P .05) of 30-day readmission.A total of 11 060 hospitalized pediatric patients underwent ERCP between 2005 and 2014. Most were female (n = 8859; 81%), aged 14-20 years (n = 9342; 84%), and white (n = 4230; 45%). Most (85%) of ERCPs were therapeutic, and leading indications were biliary (n = 5350; 48%) and pancreatitis (n = 3218; 29%). Thirteen pecent of patients were readmitted post-ERCP. Odds for 30-day readmission were highest for patients with a history of liver transplantation, age 0-4 years, male sex, and obesity (P .001 for each). Patients in both urban teaching and urban hospitals had much lower odds than those in rural hospitals for prolonged length of stay associated with ERCP.These data represent a comprehensive study of nationwide trends in age-specific volumes and outcomes following ERCP in the pediatric population and provide important insights into trends in pediatric pancreaticobiliary disease management, as well as practice setting, patient characteristics, and patient comorbidities associated with pediatric post-ERCP outcomes, including readmission and length of stay.
