SCORTEN SCALE. This scale is an illness "severity scale" which determines mortality rates. It is specific to the mortality scoring of Toxic Epidermal Necrolysis. The scale is used to predict mortality rates of these and other similar patients on an admission evaluation. The SCORTEN scale uses 7 independent factors including: an age geater than 40 years old; a heart rate greater than 120 beats/min; the presence of cancer or hemopathy; any detached-comprimised body surface area greater than 10% (same ratings used to assess "burned body mass"; a serum BUN level greater than 27 mg/dL; a serum bicarbonate level of less than 20 mEq/L; and a serum glucose level greater than 252 mg/dL. The absence of these risk factors, or presence of 1 risk factor is associated with a 3% mortality rate which increases to 21.1% mortality with 2 of these risk factors. Three of these risk factors increast the mortality rate to 35%. Four of the risk factors increase mortality rates to 58% and 90% with 5 or more of these risk factors. The SCORTEN scale is most often used for conditions involving the integrity of the skin and mucous membranes of the body. It can be used with burn victims, sufferers of Stevens-Johnson Syndrome, cutaneous drug reactions, or exfoliative wounds. A SCORTEN rating is almost always used in determining the mortality rates of patients having Toxic Epidermal Necrolysis. The SCORTEN was developed in 2000, the validation research was completed in Europe by Sylvie Bastuji-Garin.
