Validation of a Simple Score for Mortality Prediction in a Cohort of Unselected Emergency Patients

Table 4

Comparison of the AUROC of SPS and ESI. Comparison of the area under the curve of the receiving operating characteristics of the Simple Prognostic Score and Emergency Severity Index.

	AUC SPS (CI 95%)	AUC ESI (CI 95%)	-value
7-day mortality	0.897 (0.863–0.931)	0.715 (0.646–0.784)	0.011
30-day mortality	0.865 (0.833–0.898)	0.688 (0.642–0.734)	<0.001
1-year mortality	0.848 (0.831–0.865)	0.632 (0.608–0.656)	<0.001

SPS, simple prognostic score; ESI, emergency severity index; AUROC, area under the curve of the receiving operating characteristics; AUC, area under the curve.
