In intensive care unit (ICU) patients, the ability to predict delirium may help reduce its incidence, duration, and severity. The PREdiction of DELIRium in ICU (PRE-DELIRIC) model was recently developed for this purpose. Our aim was to test the PRE-DELIRIC model in the medical ICU.

Delirium, a disturbance of consciousness with an acute onset and a variable course of impaired cognitive functioning, is common in patients admitted to the ICU. Several tools are available for assessing delirium in ICU patients, of which the confusion assessment method-intensive care unit (CAM-ICU) has the highest sensitivity and specificity.

Although several predictive models for non-intensive care patients exist, as well as one for older medical intensive care patients, no evidence based prediction model for general intensive care patients is available. Also the tools are not involved the metabolic parameters which cause delirium. Because of that the tool need to have biochemical parameters.

In the light of these information our aim is to validate the PRE-DELIRIC model in medical ICU in Turkish people.
