Abstract

Objectives: The incidence rates of acute pancreatitis (AP) and the prevalence of class III obesity, and metabolic syndrome (MetS) are increasing in the US. Since class III obesity was associated with adverse clinical outcomes of AP, we sought to understand if the presence of metabolic comorbidities collectively recognized, as MetS were associated with worse clinical outcomes and increased health-care utilization.

Methods: The Nationwide Readmissions Database (NRD) (2010-2014) was reviewed to identify all adult subjects with a principal discharge diagnosis of AP. Inpatient mortality, severe AP (SAP), and 30-day readmissions were the primary outcomes analyzed. Propensity score weighted analyses were used to compare AP subjects with and without MetS and were further stratified by class III obesity status.

Results: MetS was associated with 12.91% (139,165/1,078,183) of all admissions with AP. Propensity score weighted analyses showed that MetS was associated with an increased proportion of SAP (OR 1.21, 95% CI 1.17, 1.25), but decreased mortality (OR 0.62, 95% CI 0.54, 0.70) and 30-day readmissions (OR 0.86, 95% CI 0.83, 0.89). Propensity score weighted analyses also revealed that class III obesity was independently associated with increased mortality in AP subjects with (OR 1.92, 95% CI 1.41, 2.61) and without MetS (OR 1.55, 95% CI 1.26, 1.92), and increased SAP in subjects with and without MetS.

Conclusions: Class III obesity appears to be the primary factor associated with adverse clinical outcomes in subjects with MetS admitted with AP. This has significant implications for patient management and future research targeting AP.

Study schema to assess the impact of metabolic syndrome and class III obesity on acute pancreatitis outcomes. * The numbers for the no class III obesity and class III obesity in the no metabolic syndrome groups do not add up to exactly 939,018 because of the rounding that occurred after we applied the weights to produce national estimates. At this point the results are no longer whole numbers but have several decimal places which were then rounded by the statistical software utilized.

Trend Analyses using the Nationwide Readmission Database (2010 – 2014). There was a significant increase (p < 0.001) in hospitalizations with (A) acute pancreatitis (B) metabolic syndrome, (C) acute pancreatitis with metabolic syndrome, and (D) the individual components of the metabolic syndrome.
