Edna and Bjerkeset identified risk factors associated with infection in trauma patients, including the amount of blood transfused. This can help identify a patient who may require closer monitoring and more aggressive management. The authors are from Innherred Hospital in Levanger, Norway.
Parameters:
(1) Injury Severity Score (ISS)
(2) age of the patient in years
(3) surgery
(4) amount of blood transfused
