🏥 LACE Index (Readmission Risk)
UseWhen to use: discharge planning and transitional-care targeting.
Strata≥10 flags higher 30-day readmission or death risk in the original cohort.
LimitsWhen not to use: as sole denial of admission or rehab. · Pitfall: incomplete Charlson coding. · Local calibration may differ.

How it works
LOS points + emergent admit (+3) + Charlson band + 6-mo ED visits.
Key points
- L+A+C+E.
- ≥10 high risk.
- Next: TOC interventions.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Length of stay (days) | 3 days (+3) |
|---|---|
| Acute / emergent admission | No (0) |
| Charlson comorbidity points | 2 (+2) |
| ED visits in past 6 months | 2 (+2) |
→LACE7/19
- Cue：5–9 — intermediate risk band
| Length of stay (days) | <1 day (0) |

FAQ
Frequently asked questions
- Does LACE Index (Readmission Risk) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is LACE Index (Readmission Risk) calculated in practice? Can you show a worked example?
- Inputs: Length of stay (days) 3 days (+3), Acute / emergent admission No (0), Charlson comorbidity points 2 (+2), ED visits in past 6 months 2 (+2) → Result: LACE 7 /19（Cue: 5–9 — intermediate risk band） Inputs: Length of stay (days) <1 day (0), Acute / emergent admission No (0), Charlson comorbidity points 0 (0), ED visits in past 6 months 0 (0) → Result: LACE 0 /19（Cue: 0–4 — lower risk band）
