The mortality of burned adults can be predicted based on a composite measurement scale which is simple to use.
Patient population: >= 15 years of age
score =
= (2 * (age value)) + (percentage of total BSA burned)
where:
• The percentage of total BSA burned is a number from 0 to 100.
• Often the percentage of BSA involved is the sum of second and third degree burn areas; here it appears to be the total area burned.
• The age value is determined as:
|
age in years |
age value |
|
<= 50 |
0 |
|
> 50 |
(age - 50) |
Interpretation:
• minimum score: 0
• maximum score: 200 (for all practical purposes, although higher scores possible in the very elderly)
