Table 4. Comparison of savings achieved and readmissions prevented for post-discharge programs with different costs and efficacies.

Three policies are compared: patient specific analysis using the classifier, patient-specific analysis using LACE, best uniform policy. For comparison of savings an additional column demonstrates the policy that applies intervention to every patient may lead to loss (or savings).
