LACE index
The LACE index uses 4 variables to predict the risk of death or urgent readmission within 30 days after hospital discharge among medical and surgical patients: length of hospital stay (L), acuity of admission (A), comorbidity (C) and emergency department utilization in the 6 months before admission (E).

Clinical indication
The LACE index is intended for patients about to be discharged from the medical or surgery wards into the community. 

The LACE index is not intended for use outside of the medical and surgery wards, or for patients not being discharged to the community.
