Background
While patient- and hospital-level factors affecting outcomes of patients undergoing pancreatoduodenectomy (PD) have been well described separately, the relative impact of these factors on in-hospital mortality has not been comprehensively assessed.
Methods
Retrospective review of the National Inpatient Sample database (January 2004–December 2014) was conducted to identify patients undergoing PD. Factors associated with in-hospital mortality after PD were analyzed after adjusting for previously defined patient- and hospital-level risk factors.
Results
A total of 9639 patients who underwent a PD at 2325 hospitals were identified. Median patient age was 57 years (IQR 66–73). Overall, mortality following PD was 3.2%. When patient- and hospital-level characteristics were analyzed in the same model, patient-level characteristic associated with increased odds of in-hospital mortality included increasing patient age (OR 1.05, 95% CI 1.03–1.06/per 5 years increase), male sex (OR 1.47, 95% CI 1.16–1.86), the presence of liver disease (OR 3.03, 95% CI 1.99–4.61), chronic kidney disease (OR 1.78, 95% CI 1.18–2.68), and congestive heart failure (OR 2.48, 95% CI 1.65–3.74). The only hospital characteristic associated with odds of mortality following PD included compliance with Leapfrog volume standards (OR 0.70, 95% CI 0.54–0.92).
Conclusion
Patient-level factors, such as advanced comorbidities, male sex, and increased age, contributed the most to increased risk of mortality after PD. Hospital volume was the only hospital-level factor contributing to risk of in-hospital mortality following PD.
