Objective: To examine the blood product orders and usage rates made by emergency physicians to determine whether the requests for blood products are excessive. Material and Method: This prospective, observational, and single-center study analyzed demographic data, indications for blood transfusion, and transfusion rates of patients aged 18 years and older admitted to a tertiary adult emergency department in five months. Results: One thousand four hundred seventy-five blood product orders (with a mean of 6.92 units per patient) were examined. Of 63.1%, these orders were not used. The transfusion rates were 40.89 % for erythrocyte suspension (ES), 25.61% for thrombocyte suspension (TS), and 44.34% for fresh frozen plasma (FFP). The main indications for requesting blood products were gastrointestinal bleeding and anemia. Specifically, 30.04% of ES, 31.9% of TS, and 60.56% of FFP were used for patients with gastrointestinal bleeding. In trauma patients, 12.75% of requested ES, 0.083% of TS, and 13.89% of FFP were utilized. Conclusion: Excessive requests for blood products in the emergency department result in a significant waste of resources. The transfusion committee should develop specialized strategies and increase physician awareness to reduce unnecessary requests and optimize resource utilization.
