Intensive Care Unit Delirium and Intensive Care Unit–Related Posttraumatic Stress Disorder

Abstract

<p id="P3">Delirium is one of the most common behavioral manifestations of acute brain dysfunction in Intensive Care Unit (ICU) and is a strong predictor of worse outcome. Routine monitoring for delirium is recommended for all ICU patients using validated tools (e.g., CAM-ICU, ICDSC). In delirious patients, a search for all reversible precipitants is the first line of action and pharmacological treatment should be considered when all causes have been ruled out, and not contraindicated. </p><p id="P4">Long-term morbidity, in the forms of cognitive, physical and psychological impairments, has significant consequences for survivors of critical illness and for their caregivers. ICU patients may develop PTSD anchored to their critical illness experience, with ICU-related PTSD incidence rates of 10%. Using ICU diaries during a critical illness may minimize the occurrence of future ICU-related PTSD. </p>
