Demonstration of a U.S. nationwide reduction in transfusion in general surgery and a review of published transfusion reduction methodologies

Abstract

Background Red blood cell transfusions in surgical procedures can be lifesaving. However, recent studies show transfusions are associated with a dose‐dependent increase in postoperative morbidity and mortality; hospitals and physicians have attempted to reduce them. We sought to determine the success of these efforts and review and summarize published reduction methods employed. Study Design/Methods An analysis of transfusion data from ACS‐NSQIP public use files of general surgical procedures for 2012 and 2018; a retrospective review of the literature surrounding general surgical transfusion reduction from 2008 to 2018. Results The rate of general surgical transfusion in the NSQIP dataset decreased from 5.5% in 2012 to 4.0% in 2018, a 27% relative reduction in transfusion. After extensive multivariable adjustment for patient risk and operative complexity, this effect remained (Odds ratio 0.65, 95% CI 0.63–0.67, p < .001). Furthermore, there was a positive correlation between specific procedure decreases in transfusion and decreases in 30‐day morbidity (rho =0.41, p = .003) and mortality (rho = 0.37, p = .007). There were 866 published studies matching our search term “red blood cell transfusion reduction.” Forty‐four were relevant to general surgery. Seven dominant strategies for transfusion reduction by descending frequency of report included restrictive transfusion thresholds, management of preoperative anemia, perioperative interventions, educational programs, electronic clinical decision support, waste reduction, and audits of transfusion practices. Conclusion Our study demonstrates a 27% decrease in general surgery transfusion between 2012 and 2018 with associated reductions in morbidity and mortality, suggesting published employed strategies have been successful and safely implemented.

Implementation of a patient blood management in an Italian City Hospital: is it effective in reducing the use of red blood cells?

“…Even in pancreatic surgery, after PBM implementation, only 19% of resected patients required transfusion. Similar results have been reported in a recent large study using the US nationwide database; even after liver resection, 30% of patients received blood transfusion in the most recent period [17].…”

“…Patient blood management (PBM) has been introduced in the last decade to reduce the use of blood products and improve tolerance to anemia [10][11][12][13][14]. Most data regarding the relationship between the implementation of PBM and the reduction in the consumption of blood products come from North America [14][15][16][17].…”
