SCORTEN scale

The SCORTEN scale (SCORe of Toxic Epidermal Necrosis) is a severity-of-illness scale with which the severity of certain bullous conditions can be systematically determined. It was originally developed for toxic epidermal necrolysis,[1] but can be used with burn victims, sufferers of Stevens–Johnson syndrome, cutaneous drug reactions, or exfoliative wounds.[citation needed] These conditions have in common that they compromise the integrity of the skin and/or mucous membranes.

In the SCORTEN Scale 7 independent risk factors for high mortality are systematically scored, so as to determine the mortality rate for that particular patient.

Risk factor 0 1
Age < 40 years > 40 years
Associated malignancy no yes
Heart rate (beats/min) <120 >120
Serum BUN (mg/dL) <28 >28
Detached or compromised body surface <10% >10%
Serum bicarbonate (mEq/L) >20 <20
Serum glucose (mg/dL) <252 >252

The more risk factors present, the higher the SCORTEN score, and the higher the mortality rate, as shown in the following table.

No of risk factors Mortality rate
0-1 3.2%
2 12.1%
3 35.3%
4 58.3%
5 or more >90%
