Evaluation of the potential impact of the peri-operative transfusion trigger score algorithm on the optimization of blood components: A comparative study in a trauma hospital.

UNLABELLED: Red blood cell transfusion in trauma surgery continues to be guided primarily by isolated hemoglobin (Hb) values despite the risks associated with over-transfusion.

OBJECTIVE

This study aimed to evaluate whether the retrospective application of the peri-operative transfusion trigger score (POTTS) algorithm could reduce transfusion events in trauma patients. A one-year retrospective analysis was conducted comparing transfusions performed under standard clinical practice (liberal or restrictive management based on hemoglobin levels). The POTTS algorithm was applied, with suggestions to supplement it with the bleeding score and to further refine the algorithm for trauma patients (T-POTTS).

RESULTS

The POTTS algorithm, which incorporates specific patient physiological parameters to determine a transfusion threshold, identified a significant number of potentially avoidable events and suggested that decisions based solely on Hb may not optimize the actual need for red blood cell transfusion in trauma patients.

CONCLUSIONS

The use of POTTS in trauma patients could decrease unnecessary transfusion events, dismissing the importance of considering physiological parameters in transfusion decision-making.
