Lui CT, et al. - The current existing predictive models for massive blood transfusion in major trauma patients demonstrate limitations for sequential evaluation of patients and lack of dynamic parameters. Researchers here aimed to establish a predictive model for predicting the need of massive blood transfusion major trauma patients, integrating dynamic parameters. Along the trauma care pathway, the dynamic MBT (DMBT) score allowed both snapshot and sequential activation. In addition, it demonstrated better performance than the PWH score and TASH score.
