**6.2 SCORTEN scale (SCORe of toxic epidermal necrosis) for predicting mortality risk in SJS/TEN**

SCORTEN scale is the severity-of-illness scale that measures the severity of certain bullous conditions and can be helpful in systematically determining the disease/reaction prognosis. The table below (**Table 3**) provides details of seven independent risk factors that need to be evaluated within the first 24 hours of admission or within the first 5 days of reaction that will add to accuracy in predicting mortality. The presence of prognostic factors is given a score of 1 and if not present then assign the score of 0. SCORTEN score is the summation of these individual scores allotted to each of the seven prognostic factors based on their presence or absence that gives the overall prognosis in terms of percentage mortality. More risk factors present, the higher the SCORTEN score, and the higher the mortality rate [29].
