Perioperative blood transfusion is associated with an increased risk for post-surgical infection following pancreaticoduodenectomy

Abstract

Background/PurposePerioperative blood transfusion is common after pancreaticoduodenectomy (PD) and may predispose patients to infectious complications. The purpose of this study is to examine the association between perioperative blood transfusion and the development of post-surgical infection after PD. MethodsPatients who underwent PD from 2014 to 2015 were identified in the NSQIP pancreas-specific database. Logistic regression analysis was used to compute adjusted odds ratios (aOR) to identify an independent association between perioperative red blood cell transfusion (within 72 h of surgery) and the development of post-operative infection after 72 h. ResultsA total of 6869 patients underwent PD during this time period. Of these, 1372 (20.0%) patients received a perioperative blood transfusion. Patients receiving transfusion had a higher rate of post-operative infection (34.7% vs 26.5%, p < 0.001). After adjusting for significant covariates, perioperative transfusion was independently associated the subsequent development of any post-operative infection (aOR 1.41 [1.23–1.62], p < 0.001), including pneumonia (aOR 2.01 [1.48–2.74], p < 0.001), sepsis (aOR 1.62 [1.29–2.04], p < 0.001), and septic shock (aOR 1.92 [1.38–2.68], p < 0.001). ConclusionThere is a strong independent association between perioperative blood transfusion and the development of subsequent post-operative infection following PD.
