We will evaluate the effect of red blood cell (RBC) transfusion on fatal and non fatal events
according to baseline risk of death in an international cohort of trauma patients (CRASH-2
trial). The following outcomes will be considered: death from all causes, death due to
bleeding, death due to multiorgan failure, death due to vascular occlusive events and non
vascular occlusive events. Non fatal outcomes include: myocardial infarction, stroke, deep
vein thrombosis and pulmonary embolism.
