Table 2.
Calculation of the Severity-of-Illness Score for Toxic Epidermal Necrolysis (SCORTEN) in our patient
| Risk factor | Score | Patient score | |
|---|---|---|---|
| 0 | 1 | ||
| Age | < 40 years | > 40 years | 1 |
| Associated malignancy* | No | Yes | 0 |
| Heart rate (beats/min) | < 120 | ≥ 120 | 1 |
| Serum urea (mg/dL) [mmol/L] | ≤ 28 [10] | > 28 [10] | 1 |
| Detached or compromised body surface | < 10% | ≥ 10% | 1 |
| Serum bicarbonate (mEq/L) | ≥ 20 | < 20 | 0 |
| Serum glucose (mg/dL) [mmol/L] | ≤ 250 [14] | > 250 [14] | 0 |
| Total | 4 | ||
More risk factors result in a higher score and a higher mortality rate (%) as follows:
0–1 = 3.2% (CI: 0.1-16.7)
2 = 12.1% (CI: 5.4-22.5)
3 = 35.5% (CI: 19.8-53.5)
4 = 58.3% (CI: 36.6-77.9)
≥5 = 90% (CI: 55.5-99.8)
CI: Confidence Interval [42, 43]
