National analysis of whole blood and component versus component transfusions in civilian trauma patients who underwent a thoracotomy or laparotomy: Toward improving patient outcomes and quality of care

Abstract

BackgroundThis study aimed to investigate the associations of whole blood and component versus component transfusions with in-hospital mortality, complication rates, intensive care unit length of stay, and packed red blood cells transfusion volumes in adult civilian trauma patients. MethodsWe performed a retrospective cohort study of the American College of Surgeons Trauma Quality Program Participant Use File 2016 to 2019 dataset. Adult civilian trauma patients (aged >18 years) sustaining injuries of at least moderate severity who received whole blood and component or component within 4 hours of arrival and underwent thoracotomy or laparotomy were included. Multivariable regression analysis was used to compare outcomes between whole blood and component and component groups. ResultsA total of 37,384 patients met eligibility criteria, of which 218 received whole blood and component and 37,166 received component. There was no significant difference in in-hospital mortality between whole blood and component and component groups for those who underwent thoracotomy (adjusted odds ratio = 0.408, P = .413) or laparotomy (adjusted odds ratio = 1.046, P = .857). Thoracotomy patients who received whole blood and component had no difference in 4-hour or 24-hour pack red blood cell volumes (3336 mL vs 3106 mL, P = .754; 3 658mL vs 3,636mL, P = .982), intensive care unit length of stay (10.68 days vs 8.63 days, P = .542), or complications rates compared to those who received component. Laparotomy patients who received whole blood and component had no difference in 4 hour or 24-hour packed red blood cell volumes (2,758 mL vs 2,721mL, P = .927; 3,538 mL vs 3,385 mL, P = .754), intensive care unit length of stay (11.78 days vs 9.90 days, P = .177), or complications rates compared to those who received component. ConclusionStudy findings have indicated that a combined resuscitation with whole blood and component transfusion in adult civilian trauma patients is a viable alternative to component transfusion alone.
