Incidence and Predictors of 30-Day Readmission among Patients Hospitalized for Chronic Pancreatitis

Chronic pancreatitis (CP) hospitalizations along with associated morbidity and costs are increasing. The goal of this study was to use the National Readmission Database to identify the incidence and risk factors for 30-day readmissions among patients with CP. Methods We performed a retrospective analysis of National Readmission Database from January 2013 to December 2013 to determine patient demographic and clinical characteristics predictive of 30-day hospital readmission for adult patients (aged >18 years) discharged with a principle diagnosis of CP. A survey logistic regression model was used to determine the predictive value of selected variables for 30-day readmission. Results In 2013, 12,545 admissions with primary diagnosis of CP were noted, and 30.4% were readmitted within 30 days. Cholecystectomy (odds ratio [OR], 0.53; P = 0.0024) or endoscopic retrograde cholangiopancreatography (OR, 0.70; P = 0.01) during index admission was associated with decreased all-cause readmissions. Pancreatectomy during index admission was associated with reduced (OR, 0.2; P = 0.0005) pancreatitis-related readmissions. Conclusions Hospital readmissions for CP are frequent and pose a significant healthcare burden. Performing cholecystectomy, endoscopic retrograde cholangiopancreatography, or pancreatectomy during index admission was associated with reduced odds of readmission.
