Comparison of PRE-DELIRIC and Acute Brain Dysfunction-Prediction Models

Model Characteristic	PRE-DELIRIC and E-PRE-DELIRIC (Logistic Model)	Acute Brain Dysfunction-Prediction Model (Multinomial Logistic Regression)
Time-varying predictors (daily)	No	Yes
Outcome	Delirium	Next day status: normal, delirium, coma, ICU discharge, ICU death
Outcome frequency	One per patient	One per patient-day
Competing risk	Does not account	Accounts for competing risks
Excludes patients with delirium at admission	Yes	No

E-PRE-DELIRIC = Early Prediction of Delirium in ICU Patients; PRE-DELIRIC = Prediction of Delirium in ICU Patients.
