Delirium in The Intensive Care Units

Health complications among elderly inpatients are an increasing problem worldwide, resulting in a growing need for the implementation of effective preventive strategies .One of the most common in-hospital complications is delirium,which according to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) is defined as “an acute and fluctuating alteration of attention and awareness that is accompanied by a change in cognition that cannot be better accounted for by a preexisting or evolving dementia, and is a direct consequence of some medical condition” .The consequences of delirium place a considerable burden on both patients and medical staff because of increased morbidity, higher mortality rates, incomplete functional cognitive recovery, prolonged hospitalization, and increased costs of long-term treatment. So, the aim of this article is to review researches on delirium and suggest future directions in research and clinical practice.In conclusion; more delirium guideline evaluation studies are needed to determine their effect on clinical practice.
