Bacground and Objective: The Intensive Care Unit (ICU) is one of the most stressful places in the hospital; Not only for patients but also for the closest family members of the patient who may experience an emotional crisis. Patients admitted to the intensive care unit experience emotional crises due to the conditions of this ward, the increase of such crises leads to various psychological disorders as well as depression or dementia. Depression and other psychological problems are associated with a variety of other chronic medical conditions and often goes undiagnosed due to the focus of physicians and patients on the underlying disease.
Results: The most common psychological diagnosis among ICU patients is delirium. Numerous factors such as severe depression, postoperative hypoxia, marital status, and the use of opioids and haloperidol have been reported as predictors of delirium. The incidence of delirium in the intensive care unit is not specific to patients with brain injuries or other severe injuries. In cardiovascular patients admitted to the intensive care unit, the prevalence of psychological disorders, including depression, is reported to be about 30%. In this regard, research has shown that depression is very common in patients undergoing treatment for acute coronary syndrome. In addition to the mental disorders caused by admission in the ICU, there are other mental conditions, including post-traumatic stress disorder and preexisting psychiatric disorders, which according to our studies are less prevalent compared to depression and delirium. Early detection and reduction of risk factors affecting delirium requires knowledge and awareness of physicians.
Conclusion: The present study was conducted with the aim of reviewing the prevalence of Psychological disorders in intensive care units
