Prediction of Massive Transfusion in Trauma Patients

"Our Study is an observational non-interventional study based on a multicentric anonymized registry. It's an external validation of pre-existing prognostic scores of traumatic haemorrhages at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion and haemorrhagic death.~The statistic intervention will be a comparison of score performances (Overall performance, discrimination and calibration)."
