Whole Blood in Trauma Resuscitation: What Is the Real Cost?

Whole blood (WB) has gained popularity in trauma resuscitation within the past 5 y. Previously, its civilian use was limited due to advances in blood component fractionation and fears of hemolysis and infectious disease transmission. Although there are studies and review articles on the efficacy of WB, the analysis of cost pertaining to the use of WB is limited.

We performed a retrospective 1:1 propensity-matched analysis of 280 subjects comparing trauma patients receiving resuscitation with blood component therapy (BCT) to those receiving WB plus BCT between January 2014 and July 2019. WB was used for patients who arrived in hemorrhagic shock with systolic blood pressure <90 mmHg due to either penetrating or blunt trauma. Endpoints included the number of units of WB, packed red blood cells (PRBCs), fresh frozen plasma (FFP), platelets, and cryoprecipitate each patient received. Institution costs for each component were compared in the form of price ratios. Comparisons were made using Wilcoxon rank-sum tests with a P value of ≤0.05 considered statistically significant.

The use of WB was associated with a statistically significant decrease in the number of PRBCs used when compared to BCT. This holds true with the cost of PRBCs being lower among the WB group when the price is controlled. Similarly, a trend was found where FFP, platelets, and cryoprecipitate use and cost showed an absolute decrease between WB and BCT groups. The use of WB is associated with decreased total cost as well (P = 0.1660), although not statistically significant.

Adding WB to BCT for trauma resuscitation was associated with lower red blood cell use and cost. A similar trend was found that absolute total cost and absolute cost of FFP, platelets, and cryoprecipitate use was lower when WB was added. WB wastage was minimized due to repurposing WB into PRBCs when WB lifespan ended.
