Siregar et al reported a model for predicting short-term mortality for a patient with diabetic ketoacidosis (DKA). This can help to identify a patient who may benefit from more aggressive management. The authors are from University of Indonesia and Cipto Mangunkusumo General Hospital.
Patient selection: adult >= 18 years of age (mdian age 55 years)
Parameters:
(1) history of diabetic ketoacidosis (DKA)
(2) Glasgow coma scale (GCS)
(3) serum lactate in mmol/L
(4) Charlson Comorbidity Index (CCI)

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 6
• The higher the score the greater the 72-hour mortality.
