Table 1 Variables included in the different models of the AKIpredictor [19]

From: Machine learning versus physicians’ prediction of acute kidney injury in critically ill adults: a prospective evaluation of the AKIpredictor

Admission

Blood glucose upon ICU admission

Suspected sepsis upon ICU admission (yes/no)

Hemodynamic support upon ICU admission (none/mechanical/pharmacological/both)

Day1

Serum creatinine

APACHE II score

Maximum lactate

Bilirubin

Hours of ICU stay

Day1+

Total amount of urine

Urine slope1

Time the mean arterial blood pressure is above its average value

Time the mean arterial blood pressure is below 60 mmHg

Pharmacologic hemodynamic support (cumulative dose of inotropes and vasopressors)

  1. The day1 model also uses the predictors of the admission model; the day1+ model also uses the predictors of the day1 and admission models
  2. Abbreviations: APACHE Acute Physiology and Chronic Health Evaluation, ICU intensive care unit
  3. 1The urine slope refers to the slope of a linear model fitted to the hourly urine values
