BACKGROUND Drug-induced acute pancreatitis (DIAP) linked to several medications is a diagnosis of exclusion and is associated with significant morbidity and mortality, contributing to the US healthcare cost burden. Existing studies on DIAP focus on the drug classes that can cause acute pancreatitis. Hence, our retrospective study aims to determine the rates and predictors for 30-day readmissions (30-DR) in patients with index hospitalization for DIAP. PATIENTS AND METHODS From the Nationwide Readmissions Database, we followed adults admitted for DIAP who were discharged alive for 30 days. During 30-DR, we evaluated the rates, predictors, and outcomes of DIAP. RESULTS Of the 4457 DIAP patients surviving at discharge, 12.5% were readmitted at 30- -days. During readmissions, the predictors of 30-DR for DIAP are advancing age, the Charlson-Deyo Comorbidity Index of 2 and 3, protein-energy malnutrition, and dyslipidemia. During 30-DR, DIAP had a higher risk of mortality rate (2.4%. vs. 0.7%; p<0.02), extended hospital stays (5.6 -days vs. 4-days, <0.0001), and higher hospital charges ($12,983.6 vs. $8,255.6; P<0.0001). CONCLUSIONS Drug-induced acute pancreatitis has high 30-DR rates and poorer outcomes.
