🔥 Abbreviated Burn Severity Index (ABSI)
Estimate burn severity and survival with the Abbreviated Burn Severity Index.
Abbreviated Burn Severity Index (ABSI)
Sex
Age
Inhalation injury
Full-thickness (3rd degree) burn
Burn area %TBSA
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.
