    INSTRUCTIONS

    Note: This calculator is not externally validated and should be used with caution. It is not intended to routinely disposition patients. The APACHE II Score may be a better mortality predictor. Use in patients with DKA.

    When to Use
    Why Use

    Patients with DKA. Study population included patients with  serum glucose >250 mg/dL (14.1 mmol/L), positive urine ketones, and metabolic acidosis (arterial blood pH <7.30 and HCO₃ <15 mEq/L (15 mmol/L).

    Provides information regarding mortality in patients presenting with DKA.
