Comparison of the accuracy of two methods on detection of the prognosis of mortality in patients with trauma admitted to the intensive care units of Alzahra hospital, Isfahan, Iran, in 2015

Abstract

Background: Recently, there are many scoring systems to determine the mortality rate among the patients with trauma. The aim of this study was to compare the Simplified Acute Physiology Score (SAPS) III and Sequential Organ Failure Assessment (SOFA) tests in determining the degree of mortality in patients with trauma admitted to the intensive care units (ICU). Methods: In this retrospective cross-sectional study, mortality rate was assessed using of SOFA and SAPS III scorings on 100 patients with trauma who admitted to the intensive care units of Alzahra hospital, Isfahan, Iran, in 2015, according to the inclusion and exclusion criteria. The patients were also divided into two groups of survive and non-survive based on mortality. Findings: The mean SOFA scores in survive and non-survive groups were 6.20 ± 2.97 and 14.16 ± 2.69, and mean SAPS III scores were 35.02 ± 12.67 and 60.96 ± 13.54, respectively. The SOFA and SAPS III scores in the nonsurvive group were significantly higher than survive group (P < 0.001 for both tests). Sensitivity and specificity rates of the SOFA test were 69.26 and 29.92, and for SAPS III test, 68.22 and 32.25, respectively. Conclusion: Both SOFA and SAPS III scorings are good criteria for predicting mortality in patients with trauma admitted to the intensive care units. So, the sensitivity and specificity of the two tests were roughly similar, but the convenience and simplicity of the SOFA test were more in determining of mortality rate. © 2018, Isfahan University of Medical Sciences(IUMS).
