Original method The original<unk>  was the addition of two factors, the first being the total body surface area affected by burning (usually estimated using the Wallace rule of nines, or calculated using a Lund and Browder chart) and the second being the age of the patient. The score is expressed as: : The score is a comparative indicator of burn severity, with a score over 140 considered as being unsurvivable, depending on the available treatment resources. Modified method Research demonstrated that with improvements in medical care rendered the original method too pessimistic in its outcome prediction. This resulted in the publication of a modified methodology which took into account the effect of inhalation injury. It was found that inhalation injury resulted in an increase of around 17 on the<unk> , and this addition means that a patient with inhalation injury would have their score calculated by body area affected + age of patient + 17. Recent analysis of mortality in burn units worldwide has shown that for well performing units the LD50 (the point at which 50% of patients would be expected to die) for major burns has significantly improved and the best units have a modified<unk>  of 130-140. This means that all burns in children (except 100% TBSA full-thickness burns) should be considered survivable injuries and actively treated.
