RESUMO
BACKGROUND AND AIMS: The aim of this study was to evaluate the diagnostic accuracy of sepsis markers and to develop a multiparametric score, using demographic and clinical variables as well as laboratory parameters to predict sepsis in patients admitted in the ED with suspected symptoms. MATERIALS AND METHODS: Patients with clinical presentation of suspected sepsis were enrolled in the ED of San Donato Hospital in Arezzo between September 2019 and May 2020. Anagraphic, anamnestic, clinical and laboratory data were collected for all subjects. PCT, MDW, WBC, MPV and BT were utilised to formulate FANS score. RESULTS: The AUC of the FANS score, PCT, MDW and CRP was 0.87, 0.80, 0.77 and 0.71, respectively, when used to predict sepsis in all 308 subjects. Instead, the AUC of the FANS (Fighting Action To Neutralize Sepsis) score, PCT, MDW and CRP was 0.93, 0.84, 0.83 and 0.77, respectively, when used to predict sepsis excluding subjects with infection (clinically classified as the Infections group). CONCLUSIONS: The results obtained with PCT, PCR and MDW confirm the results of these markers for the identification of sepsis obtained from other studies. The multiparametric approach, obtained from the statistical study of the parameters using binary logistic regression, identified those PCT, WBC, MPV, BT and MDW as the most significant and effective clinical classifiers for diagnosing sepsis.
