Key result
A LACE index ≥ 10 was associated with a significantly higher risk of 30-day unplanned readmission compared to a score < 10 in medical patients (adjusted OR 4.88).

The LACE index is a valid tool for predicting 30-day unplanned readmissions and emergency department visits in medical patients in Singapore.
Tan et al. (2013) conducted a cohort in Medical inpatients at risk of readmission (n=127,550). LACE index ≥ 10 vs. LACE index < 10 was evaluated on First unplanned hospital readmission within 30 days after index discharge (OR 4.88, 95% CI 4.57-5.22, p=<0.001). A LACE index ≥ 10 was associated with a significantly higher risk of 30-day unplanned readmission compared to a score < 10 in medical patients (adjusted OR 4.88).
