This study aimed to evaluate the association between ESRD and outcomes and resource utilization of AP.Materials and methodsThe 2014 National Inpatient Sample database was used to identify all hospitalized patients with a principal diagnosis of AP. Propensity score matching was performed to create a matched cohort of ESRD and non-ESRD patients. The in-hospital mortality, morbidity, resource utilization and expenditures of AP in ESRD patients were compared to non-ESRD patients. Multivariate analysis was performed for further adjustment for potential confounders.ResultsOf 382 595 AP patients, 7380 ESRD patients and 8050 non-ESRD patients were created after propensity score matching. ESRD patients had more tendency to have hypercalcemia-related or AP-related to other/unspecified causes, whereas non-ESRD patients had more tendency to have alcohol-related, gallstone-related, and hypertriglyceridemia-related AP. In multivariate analysis, ESRD was associated with increased in-hospital mortality, increased length of hospital stay, and increased hospitalization costs and charges. No differences were observed in inpatient morbidity, imaging study use, and procedures performed during hospitalization.ConclusionIn this large nationwide study using inpatient USA database, we demonstrate higher AP-related mortality, and resource utilization among ESRD patients when compared with non-ESRD patients.
