Common questions
What does Abbreviated Burn Severity Index (ABSI) do?
Prognosticate and guide burn-center referral after major burns.
How is the result calculated?
ABSI = sex (female 1) + age band (1–5) + inhalation injury (1) + full-thickness burn (1) + %TBSA band (1–10). Higher = lower survival.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
