The LACE index is a validated risk assessment tool, which is used to prospectively identify patients who might benefit from more intense post-discharge care. A composite risk score is generated, based upon 4 key inputs:
- L: Length of stay
- A: Acuity of admission
- C: Charlson comobidity index
- E: Number of Emergency Department Visions in the last 6 months (van Walraven et al., 2010).
web-based version of the LACE index tool has been developed by HSPRN
researchers at the University of Waterloo. Based on information input by
a clinician, the tool will generate a LACE index score for an individual
patient. It will also provide the expected risk of readmission for
an individual a recommendation as to the appropriateness of a care
transition intervention. Care transition interventions
provide integrated follow-up care in the community after an at-risk
patient has been discharged from hospital. Evidence suggests that care
transition interventions can be effective to reduce readmissions to hospital (Naylor
et al. 2011, Coleman et al. 2006).
