A Prediction Model of Mortality in Patients Hospitalized with Diabetic Ketoacidosis in a Tertiary Referral Hospital in Surabaya, Indonesia
Keywords:prediction model, mortality, diabetic ketoacidosis
Background: The mortality rate of diabetic ketoacidosis (DKA) remains high in Indonesia. Different
patterns were contributing to DKA mortality from previous studies. We aim to identify clinical and laboratory
findings as mortality predictors of DKA.
Methods: This retrospective study was conducted in a tertiary referral hospital in Surabaya. Medical records
of DKA patients from January 2016 to December 2018 were analyzed. Clinical and laboratory data were
obtained from medical records for three years period. Clinical outcome was defined as either discharged
home or death.
Results: Fifty-six among 116 DKA patients did not survive during hospitalized. Age of 60 or older, the
depressed mental state with GCS below 13, potassium serum less than 3.5 mmol/L, and bicarbonate serum
less than 15 mmol/L are found to be significant as independent factors of mortality in DKA patients.
Conclusion: The mortality rate of DKA patients in this study is still high. It independently associated
with the age of 60 years or older, depressed mental state, hypokalemia, and low bicarbonate level. Early
stratification of these predictors would help to treat patients accordingly.
