Critically ill patients can develop a host of cognitive and psychiatric complaints during their intensive care unit (ICU) stay, many of which persist for weeks or months following discharge from the ICU and can seriously affect their quality of life, including their ability to return to work. This article describes some common psychiatric problems encountered by clinicians in the ICU, including their assessment and management. A comprehensive approach is needed to decrease patient suffering, improve morbidity and mortality, and ensure that critically ill patients can return to the highest quality of life after an ICU stay.
