Prognostic value of procalcitonin and D-dimer combined with SOFA scores in sepsis

Objective: To evaluate the prognostic value of procalcitonin（PCT） and D-dimer（D-D） combined with sequential organ failure assessment（SOFA） scores in patients with sepsis. Methods: The clinical data of 100 patients with sepsis who were treated in the ICU during the period of October 2018 to May 2020 were retrospectively analyzed. The patients were divided into survival group and death group according to the prognosis of 28 d. The differences of PCT，D-D and SOFA scores between the two groups were compared，the independent risk factors affecting prognosis of patients with sepsis were confirmed by Logistic regression analysis，the combination of PCT，D-D and SOFA score was established，and the receiver operating characteristic（ROC） curve was drawn.The prognostic value of PCT，D-D combined with SOFA score in patients with sepsis was analyzed. Results:（1）The PCT（Z=-5.473，P<0.05），D-D（Z=-4.454，P<0.05） and SFOA scores（Z=-4.859，P<0.05） in death group were significantly higher than that in survival group，the difference was statistically significant. （2）Logistic regression analysis showed that PCT（OR=1.284，95%CI: 1.099-1.500），D-D（OR=1.552，95%CI:1.130-2.131） and SOFA scores （OR=1.458，95%CI:1.157-1.837） were independent risk factors for prognosis of patients with sepsis（all P<0.05）.（3）The area under the curve（AUC） of the 28 d prognosis of sepsis assessed by PCT，D-D combined with SOFA scores（0.957） was larger than that of AUC（0.883，0.811，0.838） using PCT，D-D and SOFA scores alone. The sensitivity and specificity of PCT，D-D combined with SOFA scores were 90.9% and 84.6% respectively，which were higher than those individual indicators. Conclusion: PCT，D-D and SOFA scores are independent risk factors for prognosis of patients with sepsis，and PCT，D-D combined SOFA scores is more effective than single index in evaluating prognosis of patients with sepsis.
