A severity-of-illness score that estimates the risk of death in TEN (SCORTEN) has been developed and validated. [31] Each of the following independent prognostic factors is given a score of 1:

  • Age >40 years

  • Heart rate >120 beats per minute

  • Cancer or hematologic malignancy

  • Involved body surface area >10%

  • Blood urea nitrogen level >10 mmol/L (28 mg/dL)

  • Serum bicarbonate level < 20 mmol/L (20 mEq/L)

  • Blood glucose level >14 mmol/L (252 mg/dL)
