Revised PRE-DELIRIC Model for Early Prediction of Delirium in an ICU Patient (E-PRE-DELIRIC)

Description

Wassenaar et al reported the E-PRE-DELIRIC (Early PREdiction of DELIRium in ICu patients) model for predicting delirium in an intensive care unit (ICU) patient. This can help to identify a patient who may develop delirium soon after admission to the ICU. The authors are from multiple institutions in Europe.

Patient selection: ICU patient >= 18 years of age

Parameters:

(1) age in years

(2) history of cognitive impairment

(3) history of alcohol abuse

(4) hospital service

(5) urgent admission

(6) mean arterial pressure (MAP) on admission to the ICU

(7) use of corticosteroids

(8) respiratory failure

(9) serum BUN at the time of ICU admission

Parameter	Finding	Points
age in years		0.025 * (age)
history of cognitive impairment	no	0

use of corticosteroids	no	0

X =

= SUM(points for all of the parameters) - 3.907

probability of delirium =

= 1 / (1 + EXP((-1) * X))

Performance:

• The area under the ROC curve is 0.70 for days 0-1.
