Incontinence, falls, failure to maintain adequate hydration, a prolonged hospital stay, and death are more likely to occur in the patient with delirium. 4 - 10, technique dysfunctional cognition in the delirious patient hinders communication between patient and family and between patient and health care personnel. As a result, reliable symptom assessment, counseling, and active patient participation in the therapeutic decision-making process are all compromised. 11, psychomotor agitation and emotional lability in the delirious patient may be misinterpreted as a presentation of increased pain expression.

12, consequently, conflict over the needed level of analgesia can arise among the patient, family, and staff. A potentially destructive triangle can develop when the patients family misinterprets agitation as increased pain and advocates for inappropriate escalation of opioid dosing. 13, a psychosocial intervention for family caregivers of patients with advanced cancer may be beneficial in providing knowledge of delirium and detection rates and in increasing family caregiver self-confidence in decision making. 14 references Breitbart w, gibson c, tremblay a: The delirium experience: delirium recall and delirium-related distress in hospitalized patients with cancer, their spouses/caregivers, and their nurses.

Definition, go to patient Version, delirium is a neuropsychiatric complication that can occur in patients with cancer, particularly in those with advanced disease. The prevention of delirium in the patient with cancer has not been systematically examined, but studies in hospitalized elderly patients suggest that early identification of risk factors reduces the occurrence rate of delirium and the duration of episodes. 1, delirium has been defined as a disorder of global cerebral dysfunction characterized by disordered awareness, attention, and cognition. In addition, delirium is associated with behavioral schematisch manifestations. The text revision of the fourth edition of the diagnostic and Statistical Manual for Mental Disorders (dsm-iv-tr) cites the core clinical criteria for diagnosis as follows: 3, a disturbance of consciousness with reduced clarity of awareness and attention deficit. Other cognitive or perceptual disturbances. Acuity of onset (hours to days) and fluctuation over the course of the day.

in part because there is a great deal of symptom overlap, as outlined. Key differentiating factors are the time course of development of the mental status change (especially if the patient did not have a prior dementia) and the presence of a likely precipitant for the mental status change. Individuals with delirium may also display periods of complete lucidity interspersed with periods of confusion, whereas in dementia, the deficits are generally more stable. In both conditions, there may be nocturnal worsening of symptoms with increased agitation and confusion (sundpwning). The diagnosis of delirium is complicated by the fact that there are no definitive tests for delirium. The workup for delirium includes a thorough history and mental status examination, a physical examination, and laboratory tests targeted at identifying general medical and substance-related causes. These should include urinalysis, complete chemistry panel, complete blood count, and oxygen saturation.

Infectious illnesses, especially urinary tract infections, pneumonia, and meningitis, are often implicated. The common substance-induced causes of delirium are alcohol or benzodiazepine withdrawal and benzodiazepine and anticholinergic drug toxicity, although a mber of commonly used medications, prescribed and over the counter, can produce delirium. Other conditions predisposing to delirium include old age, fractures, and preexisting dementia. Epidemiology, the exact prevalence in the general population is unknown. Delirium occurs in 10 to 15 of general medical patients older than age 65 and is frequently seen postsurgically and in intensive care units. Delirium is equally common in males and females. Clinical Manifestations, history and Mental Status Examination, history is critical in the diagnosis of delirium, particularly in regard to the time course of development of the delirium and to the prior existence of dementia or other psychiatric illness.

Delirium : MedlinePlus Medical Encyclopedia

Delirium is a reversible state of global cortical dysfunction characterized by alterations in attention and cognition and produced by a definable precipitant. Delirium is categorized by its etiology (see. Table 8-1 ) as due to general medical conditions, substance-related, or multifactorial in origin. Etiology, delirium is a syndrome with many causes. Most frequently, delirium is the result of a general medical condition; substance intoxication and withdrawal also are common causes. Structural central nervous system lesions can also lead to delirium. Table 8-2 lists common general medical and substance-related causes of delirium. Delirium is often multifactorial and may be produced by a combination bij of minor illnesses and minor metabolic derangements (e.g., mild anemia, mild hyponatremia, mild hypoxia, and urinary tract infection, especially in an elderly person). Common medical causes of delirium include metabolic abnormalities such as hyponatremia, hypoxia, hypercapnia, hypoglycemia, and hypercalcemia.
