Baker et al identified 4 risk factors associated with the need for blood transfusion in a trauma patient. The authors are from the University of Southern California in Los Angeles.
Parameters:
(1) systolic blood pressure
(2) pulse
(3) Glasgow coma score (GCS)
(4) high risk injury
High risk injuries:
(1) trauma to the chest between the midclavicular lines
(2) abdominal trauma with diffuse tenderness
(3) involvement in a vehicular accident in which one or more people have died
(4) ejection from a vehicle
(5) stab or gunshot wound to the trunk

Interpretation:
• minimum score: 0
• maximum score: 4
• The need for transfusion increases with the number of risk factors present.
