Table 4

Sensitivity and specificity for the regression model and LACE indices greater than 10 and 6.

Model	Readmitted ( = 572)	Not readmitted ( = 5290)	Sensitivity	Specificity
LACE index with cut-off of 10
Lower risk	519	5068	9.3%	95.8%
Higher risk	53	222
LACE index with optimal cut-off of 6
Lower risk	193	2820	66.3%	53.3%
Higher risk	379	2470
Regression model using variables available early in the admission with optimal cut-off
Lower risk	221	3190	61.4%	60.3%
Higher risk	351	2100
