Massive Transfusion Protocol Adherence: Relationship to Trauma Patient Outcomes.

Background: Ongoing evaluation of massive transfusion protocol adherence is critical to ensure better trauma patient outcomes.

Objective: This quality improvement initiative aimed to determine provider adherence to a recently revised massive transfusion protocol and its relationship to clinical outcomes among trauma patients requiring massive transfusion.

Methods: A retrospective, descriptive, correlational design was used to determine the association between provider adherence to a recently revised massive transfusion protocol and clinical outcomes in trauma patients with hemorrhage treated at a Level I trauma center from November 2018 to October 2020. Patient characteristics, provider massive transfusion protocol adherence, and patient outcomes were assessed. Patient characteristics and massive transfusion protocol adherence associations with 24-hr survival and survival to discharge were determined using bivariate statistical methods.

Results: A total of 95 trauma patients with massive transfusion protocol activation were evaluated. Of the 95, 71 (75%) survived the initial 24 hr following massive transfusion protocol activation and 65 (68%) survived to discharge. Based on protocol applicable items, the median massive transfusion protocol overall adherence rate per patient was 75% (IQR = 57.1-85.7) for the 65 survivors and 25% (IQR = 12.5-50.0) for the 21 nonsurvivors to discharge whose death occurred at least 1 hr after massive transfusion protocol activation (p < .001).

Conclusion: Findings indicate the importance of ongoing evaluations of adherence to massive transfusion protocols in hospital trauma settings to target areas for improvement.
