From: Using the LACE index to predict hospital readmissions in congestive heart failure patients
Showed ROC of the LACE index score to predict post discharge ED revisits at 30, 60, and 90 days. The C-statistic of the logistic regression for the LACE index to predict post discharge 30 days ED revisits is 0.6637 (95% CI: 0.5750-0.7523), 60 days post discharge ED revisits is 0.6307 (95% CI: 0.5485-0.7128), and that of the post discharge 90 days ED revisits is 0.6029 (95% CI: 0.5248-0.6809) which was more accurate than predicting hospital readmissions at the same time period in the study population though still not overwhelming (C-statistic <0.7).
