Psychiatric Morbidity After Critical Illness.

Critical illness survivors frequently have substantial psychiatric morbidity, including posttraumatic stress, depression, and anxiety symptoms. Prior psychiatric illness is a potent predictor of postcritical illness psychiatric morbidity. Early emotional distress and memories of frightening psychotic and nightmarish intensive care unit (ICU) experiences are risk factors for longer term psychiatric morbidity. ICU diaries may be effective in decreasing psychiatric morbidity after critical illness, though these and other interventions deserve further study.
