The S-S.M.A.R.T: A New Prognostic Tool for Patients with Suspected Sepsis in the Emergency Department

Table 3

Comparison between S-S.M.A.R.T and qSOFA for predicting the prognosis of patients with sepsis in the emergency department.

	AUC (95% CI)	value	ROC cut-off	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)

30-day mortality	0.786 (0.742–0.825)	<0.001	≥2	84.9	61.5	25.1	96.4
ICU admission	0.758 (0.713–0.8)	<0.001	≥2	77.6	68.8	50.3	88.3

Abbreviations: S-S.M.A.R.T (sepsis evaluation with shock index, mental status, age, and ROX index on triage), qSOFA (quick sequential organ failure assessment), AUC (area under the curve), ROC (receiver operator characteristic), PPV (positive predictive value), and NPV (negative predictive value).
