When to use

  • Estimating mortality risk in adults admitted with diabetic ketoacidosis.

Formula

Points: severe co-existing disease at presentation (6); pH <7.0 at presentation (4); insulin >50 U over first 12 h (4); glucose >16.7 mmol/L at 12 h (4); depressed mental state at 24 h (4); fever at 24 h (3). Range 0-25.

Pearls and pitfalls

  • Some inputs are recorded at 12 and 24 hours, so the final score is not available at presentation.
