Clinical takeaway

ABSI ≥ 6 warrants burn-center referral.

When to use

Prognosticate and guide burn-center referral after major burns.

How it works

ABSI = sex (female 1) + age band (1–5) + inhalation injury (1) + full-thickness burn (1) + %TBSA band (1–10). Higher = lower survival.

Key points

  • ABSI ≥ 6 warrants burn-center referral.
  • Survival figures are historical estimates.
  • %TBSA can be estimated with the rule of nines.

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.

  • Severity:8 → Severe (estimated survival ≈ 50–70%)
  • Referral:ABSI ≥ 6, high-voltage electrical burns, major associated injuries, or full-thickness burns of face/axilla/joints/hands/feet/perineum → consider a burn center
  • Note:%TBSA may be estimated with the rule of nines (second-degree and deeper only). Survival figures are historical estimates; modern critical and burn care improve outcomes

FAQ

Frequently asked questions

What are the limits and cautions when using Abbreviated Burn Severity Index (ABSI)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Abbreviated Burn Severity Index (ABSI) 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 Abbreviated Burn Severity Index (ABSI) calculated in practice? Can you show a worked example?
