ObjectiveThe aim of this study was to assess the association between whole blood (WB) and mortality among injured children who received immediate blood transfusion.BackgroundThe use of WB for transfusion therapy in trauma has been revisited, and recent studies have reported an association between WB and improved survival among adults. However, evidence of a similar association lacks in children.MethodsWe performed a retrospective cohort study from the American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) between 2020 and 2021. Patients were aged less than or equal to 16 years and had immediate blood transfusion within 4 hours of hospital arrival. Survival at 24 hours and 30 days were compared after creating 1:1 propensity score-matched cohorts, matching for demographics, injury type, vital signs on admission, trauma severity scores, hemorrhage control procedures, hospital characteristics, and the need for massive transfusion.ResultsA total of 2729 patients were eligible for analysis. The median age was 14 years (interquartile range: 8-16 years); 1862 (68.2%) patients were male; and 1207 (44.2%) patients were White. A total of 319 (11.7%) patients received WB. After a 1:1 ratio propensity score matching, 318 matched pairs were compared. WB transfusion was associated with improved survival at 24 hours, demonstrating a 42% lower risk of mortality (hazard ratio, 0.58; 95% CI, 0.34-0.98; P =0.042) Similarly, the survival benefit associated with WB transfusion remained consistent at 30 days (hazard ratio, 0.65; 95% CI, 0.46-0.90; P =0.011).ConclusionThe use of WB was associated with improved survival among injured pediatric patients requiring immediate transfusion.Copyright © 2023 Wolters Kluwer Health, Inc.
