Assessing a burn

Burns are assessed and classified according to:

  • the depth of the burn and tissue damage to underlying skin or body structures
  • the percentage of the total body surface area (TBSA) affected.

The larger the total body surface area of a burn and the deeper a burn, the greater the body’s physiological response to the burn injury. The Australian and New Zealand Burn Association (ANZBA) Referral Criteria outlines which burns require intervention through a specialist burns unit [5].
