Abstract
Physiological composite scores are used to predict mortality in multiple trauma patients. Sepsis is the leading cause of late mortality in trauma victims brought about by immune suppression due to homeostasis dysregulation. To determine whether APACHE II, SOFA, ISS and RTS scores can predict the occurrence of sepsis in multiple trauma patients. APACHE II, SOFA, ISS, and RTS scores were calculated during the first twenty-four hours after the injury for sixty-four adult poly-traumatic patients. The occurrence of infectious complications was investigated over a fourteen-day period. The infection-free rates for the multiple trauma patients were considered as end-points in the Kaplan-Meier plot analysis. For SOFA, a cutoff score of 4 points was identified as a predictor of the occurrence of sepsis, with 89% of the patients with SOFA<4 being infection-free, while 37% of those with SOFA>4 were infection-free (p<0.01). None of the patients with APACHE II≤5 points developed infections. Eighty-four percent of patients with APACHE II scores of 5-10 did not develop sepsis, while 49% with APACHE II≥11 were infection-free (p<0.01). A cutoff of 7 points was found to be most discriminative for RTS. Eighty-eight percent of the patients with RTS≤7 and 43% of those with RTS<7 were infection-free (p<0.01). Eighty-eight percent of patients with ISS≥22 did not develop sepsis and 56% with ISS>22 did not develop sepsis (p<0.01). APACHE II, SOFA, ISS, and RTS functional severity scores can predict mortality as well as the occurrence of sepsis in multiple trauma patients.
