Each score identifies individuals in the high-risk group for hospital readmission after 30 days, for example, at 10, admissions with a score of ≥10 are identified as returning to hospital within 30 days by the LACE index. LACE: Length of stay, Acuity of admission, Comorbidities based on Charlson comorbidity score and number of emergency visits in the last 6 months.
