INTRODUCTION: Recent studies have suggested the female hypercoaguable state may have a protective effect in trauma. However, whether this hypercoagulable profile confers a survival benefit in massively transfused trauma patients has yet to be determined. We hypothesized that females would have better outcomes than males after traumatic injury that required massive transfusion protocol (MTP). PATIENTS AND METHODS: All trauma patients who underwent MTP at an urban, level 1, academic trauma center were reviewed from November 2007 to October 2018. Female MTP patients were compared to their male counterparts. RESULTS: There were a total of 643 trauma patients undergoing MTP. Of these, 90 (13.8%) were female and 563 (86.2%) were male. Presenting blood pressure, heart rate, shock index, and injury severity score (ISS) were not significantly different. Overall mortality and incidence of venous thromboembolism were similar. Complication profile and hospital stay were similar. On logistic regression, female sex was not associated with survival (HR: 1.04, 95% CI: 0.56-1.92, P = 0.91). Variables associated with mortality included age (HR: 1.02, 95% CI: 1.05-1.09, P = 0.03) and ISS (HR: 1.07, 95% CI: 1.05-1.09, P < 0.001). Increasing Glascow Coma Scale was associated with survival (HR: 0.85, 95% CI: 0.82-0.89, P < 0.001). On subset analysis, premenopausal women (age < 50) did not have a survival advantage in comparison with similar aged males (HR: 0.68, 95% CI: 0.36-1.28, P = 0.24). DISCUSSION: Sex differences in coagulation profile do not result in a survival advantage for females when MTP is required.
