Yumoto et al reported a screening method to identify a trauma patient who is likely to receive massive transfusions. The authors are from Okayama University in Japan.
Patient selection: trauma
Parameters:
(1) shock index
(2) base excess in mmol/L
(3) focused assessment of sonography for trauma (FAST)
shock index =
= (heart rate) / (systolic blood pressure)

Interpretation:
• minimum score: 0
• maximum score: 3
• A score >= 1 is associated with a need for massive transfusion.
Performance:
• The area under the ROC curve is 0.93.
