The ratio of cross-matched blood to transfusion in trauma patients receiving blood in the emergency department of Besat hospital in Hamadan in 2020

Abstract Background and Objectives Trauma is one of the most common causes of emergency room visits. In the present study, the ratio of cross-matched blood to transfusion (C/T) and blood transfusion index (TI) in trauma patients receiving blood was determind to inform hospitals about the coordination between actual need and blood demand.   Materials and Methods This retrospective cross-sectional study was performed on the records of 384 patients in the emergency department of Besat Hospital in Hamadan in 1399. A checklist was used to record demographic data and the blood request form of eligible patients. Finally, the data were analyzed by independent t-test and one-way analysis of variance by SPSS software version 22.   Results Out of 813 cross-matched units, 576 blood units were injected into 384 trauma patients. C/T and TI were 1.41 and 1.51, respectively. The number of requested blood units, the number of blood transfused units, and the C/T ratio in patients with penetrating trauma (1.63±1.79) were significantly higher than non-penetrating trauma (1.26±1.09)(p< 0.0001). There was a significant relationship between the indication of blood request and the number of units of blood requested by cross-match, the number of units of blood injected and the C/T ratio (p <0.0001).   Conclusions  The present study showed that the C/T ratio and TI in trauma patients receiving blood in the emergency department of Besat Hospital in Hamadan in 1399 was favorable.
