Treatment of post-electroconvulsive therapy delirium and agitation with donepezil

Delirium and agitation are commonly encountered after administration of electroconvulsive therapy (ECT). Management is generally fairly straightforward, although some patients may have a severe, prolonged, or refractory course. We recently cared for a 65-year-old man who consistently developed severe and very prolonged post-ECT delirium that did not respond to typical pharmacological agents; the duration of delirium was dramatically shortened by the addition of donepezil. Cholinesterase inhibitors may have a place in mitigating severe and prolonged post-ECT delirium.

[Delirium]

Delirium is very common in the elderly. It complicates both psychiatric and somatic disorders and is associated with reduced survival, poor functional results, increased duration of hospital stay, and institutionalization. Diagnosis remains difficult in spite of the improvement of the diagnostic criteria, due to the polymorphism of the clinical signs and fluctuation of vigilance and cognition. Age over 70 and previous cognitive impairment are the main risk factors. Precipitating factors are medical and surgical pathologies, intoxications, especially by therapeutic drugs. Delirium can reveal or complicate a previous dementia. Prevention of delirium and care of the delirious patient require the participation of both the medical and nursing staff.

Life's Final Journey: The Oncology Nurse's Role

Despite advances in technology and science, many people diagnosed with cancer are likely to die from the disease. Because of the long-term relationships that oncology nurses develop with patients and their families during lengthy treatment periods, they are the most appropriate clinicians to provide care across the continuum and through the final journey. Care of patients in the final days of life requires a comprehensive knowledge of common syndromes, skillful assessment, and adept clinical management. Nurses cannot focus solely on the needs of patients; family members often are unaware of the dying process. Oncology nurses are uniquely qualified to provide education and support to families at the bedside witnessing the final days and hours of their loved ones. Finally, oncology nurses involved in the care of dying patients are at risk for burnout and need to provide care for their own needs to find balance between their professional and personal lives.

Acute confusion in patients with systemic cancer

OBJECTIVE

To determine the incidence, the causes and the prognostic value for survival of acute confusion (delirium) in patients admitted to a general cancer hospital.

PATIENTS

Hundred consecutive patients with confusion were examined; 78 had a metastatic disease, 11 had local tumor and 11 had no sign of tumor recurrence at admission. Patients with confusion represented 11.8% (95%CI: 9.7-14.2%) of admissions. Follow-up period lasted 18 months from the inclusion of the last patient.

RESULTS

Structural brain lesions (SBL) were mostly metastatic and caused confusion in 36 patients. 57 patients had a toxic or metabolic encephalopathy (TME). The cause remained unexplained in 6 cases, and in one patient the final diagnosis was psychotic state. Most patients with TME had more than one abnormality which could cause confusion. Confusion was reversible in 34 patients, and the odds for its regression was 3-fold higher in patients with TME (P = 0.02). Survival was significantly shorter (P = 0.02) in patients with SBL (median: 3 weeks) than in patients with TME (median: 8 weeks). However, the survival was significantly longer (P = 0.007) in patients with only one toxic or metabolic disorder (median: 20.5 weeks) than in patients with multiple changes (median: 5 weeks).

CONCLUSION

Confusion is common in general cancer population. TME is the leading etiology and it is due to multiple causes in most patients. SBL causes confusion in one third of the patients. Patients with TME have a greater chance to recover, and survive longer especially if they have only one toxic or metabolic change.

Assessing neurocognitive outcomes after critical illness: are delirium and long-term cognitive impairments related?

PURPOSE OF REVIEW

Critically ill patients have a high risk of developing neurologic dysfunction including delirium and long-term cognitive impairment. In this paper we examine possible relationships between delirium and long-term cognitive impairments and explore this in the context of critical illness.

RECENT FINDINGS

Critical illness and its treatment can lead to neurologic morbidity including neuropathological abnormalities, delirium, and cognitive impairments. The association between delirium and long-term cognitive impairments has been shown in a number of populations. Among intensive care unit cohorts, delirium appears to be one of many possible causes of cognitive impairments and may be a leading modifiable cause. The mechanisms of both delirium and intensive care unit related cognitive impairment remain unclear, although a variety of common mechanisms have been proposed.

SUMMARY

Potential neurologic consequences of critical illness include delirium and long-term cognitive impairments. Defining the extent of their association in intensive care unit cohorts is an important research priority due to the high prevalence of delirium and persistent cognitive impairments in critically ill patients. Future research should focus on strategies for the early identification of delirium and cognitive impairments, elucidating mechanisms of brain injury, and the development and implementation of therapeutic modalities designed to prevent or decrease delirium and cognitive morbidity.

Delirium in Older Adults With Cancer: Implications for Practice and Research

PURPOSE/OBJECTIVES

To provide a comprehensive review of the literature and existing evidence-based findings on delirium in older adults with cancer.

DATA SOURCES

Published articles, guidelines, and textbooks.

DATA SYNTHESIS

Although delirium generally is recognized as a common geriatric syndrome, a paucity of empirical evidence exists to guide early recognition and treatment of this sequelae of cancer and its treatment in older adults. Delirium probably is more prevalent than citations note because the phenomenon is under-recognized in clinical practice across varied settings of cancer care.

CONCLUSIONS

Extensive research is needed to formulate clinical guidelines to manage delirium. A focus on delirium in acute care and at the end of life precludes identification of this symptom in ambulatory care, where most cancer therapies are used. Particular emphasis should address the early recognition of prodromal signs of delirium to reduce symptom severity.

IMPLICATIONS FOR NURSING

Ongoing assessment opportunities and close proximity to patients' treatment experiences foster oncology nurses' mastery of this common exemplar of altered cognition in older adults with cancer. Increasing awareness of and knowledge delineating characteristics of delirium in older patients with cancer can promote early recognition, optimum treatment, and minimization of untoward consequences associated with the historically ignored example of symptom distress.

[Differential diagnosis of the Ganser syndrome. A case study]

According to the classical definition, someone with the Ganser syndrome gives 'approximate' answers, i.e. answers that are beside the point, has lowered consciousness, displays somatic conversion symptoms and suffers from pseudo-hallucinations. On the basis of the case of an 80-year-old female patient who gave approximate answers and by means of a systematic review of the literature, we give the differential diagnosis of the Ganser syndrome. The causes seem to be largely organic.

Current concepts in the management of delirum

Delirium is a serious complication of physical illness that is commonly seen in the elderly individuals admitted to the hospital. It is associated with increased mortality, increased length of stay in the hospital, institutionalization and other complications. Multiple predisposing factors in the elderly them to make vulnerable delirium. The developing diagnosis of delirium is often missed and the condition is often poorly managed. There is increasing evidence suggesting that primary prevention of delirium is the most effective treatment strategy. This article presents current management for prevention and management of delirium.

Evaluating and managing delirium, dementia, and depression in older adults hospitalized with otorhinolaryngic conditions

Nurses caring for patients who have otorhinolaryngic conditions undergoing medical and surgical treatments find that their patient populations are becoming older and sicker. These patients are more likely to develop delirium, often superimposed on depression or dementia. Sorting out the medical, surgical, and psychosocial changes in geriatric patients presents unique challenges to otorhinolaryngology (ORL) nurses. This paper reviews the evaluation and management of delirium, dementia, and depression in hospitalized elders, focusing on a new resource, the evidence-based Mental Health Toolkit, developed by the National Conference of Gerontological Nurse Practitioners (NCGNP). The paper further provides material for a structured journal club activity, including a common ORL clinical scenario and learning objectives, as well as discussion questions and answers.

[Delirium in patients with cancer]

Delirium is a frequent complication of cancer. It is the cause of patients' suffering and due to worsening of communication, the impediment to clinical assessment. It lowers the quality of life of family caregivers as well. Instant diagnosis and therapy of delirium are essential in clinical practice. In this review etiology, prevalence, clinical features and management of delirium in cancer patients are described.

[Delirium and intensive care unit syndrome]

Delirium and intensive care unit (ICU) syndrome are frequently seen postoperatively, especially in intensive care. Hospital mortality and complication rates are higher in patients with these disorders. Delirium is characterized by disturbance of consciousness and cognition and short development time. Drugs, drug withdrawal, and manifold metabolic syndromes may be causative. Knowledge of differential diagnosis and causality is essential for curative therapy. Drug therapy is recommended for the treatment of psychotic symptoms and vegetative disorders.

[Parkinson's disease: psychological and behavioral disorders]

Many patients with Parkinson's disease (PD) have clinically significant anxiety, depression, apathy, fatigue and sleep disturbances. These non motor symptoms of Parkinson's disease are still not well recognized in clinical practice, either in primary or in secondary care, and are frequently missed during routine examination, but often contribute to impair the functional abilities in PD patients. Awareness of behavioral and psychological symptoms in PD should generate new approaches to improve their diagnosis accuracy and facilitate timely therapeutic interventions.

Preoperative risk assessment for delirium after noncardiac surgery: a systematic review

Delirium is a common postoperative complication in older adults associated with adverse events including functional decline, longer lengths of stay, and risk of institutionalization. The purpose of this article is to systematically review preoperative risk factors associated with delirium following noncardiac surgery. A medical literature search was conducted using several bibliographic databases (PubMed, CINAHL, Cochrane, PsychInfo), supplemented by a manual search of the references of retrieved articles. Studies were retained for review after meeting strict inclusion criteria that included only operative patients with incident postoperative delirium diagnosed prospectively using criteria derived from the Diagnostic and Statistical Manual of Mental Disorders Third or Fourth Edition. Quantitative analyses included significance testing, homogeneity testing, and effect-size pooling. Twenty-five articles were included for review. The incidence of delirium ranged from 5.1% to 52.2%, with greater rates after hip fracture and aortic surgeries. This review found two scales, a clinical prediction rule, and a delirium risk classification system that were validated in other operative settings. Individual risk factor analysis suggested that cognitive impairment, older age, functional impairment, sensory impairment, depression, preoperative psychotropic drug use, psychopathological symptoms, institutional residence, and greater comorbidity were associated with postoperative delirium. Of the risk factors examined, evidence was most robust for an association between delirium and cognitive impairment or psychotropic drug use, with moderate effect sizes for both. Missing data and measurement differences did not allow for inferences to be made about other risk factors. Effect-size pooling supports the concept that delirium is a heterogeneous disorder with multiple risk factors. More research is needed to better identify patients at risk for postoperative delirium and to develop preventive strategies.

Unmasking delirium

The authors use a case study to illustrate the risks of delirium in older adult patients and discuss ways to prevent, identify and manage its occurrence. An estimated 60 to 80 per cent of hospitalized frail older adults experience at least one preventable episode of delirium, often leading to prolonged hospitalization, functional decline, increased morbidity and eventual nursing home placement or death. Delirium is a medical emergency, characterized by acute onset and a fluctuating course that is demonstrated by abrupt changes in mental status and function. It has three categories: hyperactive, hypoactive and mixed. Although delirium is amenable to expert nursing care, it is unrecognized or misdiagnosed in up to 70 per cent of older patients. Delirium results from the interplay of multiple forces associated with illness in the older adult, including drugs, substance abuse, metabolic disturbances, nutritional deficiencies, fluid disturbances, acute trauma or illness, infection and impaired physical or functional ability A proactive strategy for delirium prevention and treatment targets defined risk factors and the management of physiologic factors that precipitate delirium. It includes assessment, therapeutic environmental modification, standardized protocols for physiological interventions and staff education.

The spectrum of encephalopathy in critical illness

Beyond the cerebral impact of cardiac arrest, recent research indicates a high prevalence of neurological disturbances such as delirium and coma among patients admitted to the intensive care unit (ICU). These disturbances, grouped here under the term "encephalopathy," may be overlooked while attention is devoted to reversing life-threatening imbalances in cardiac and pulmonary function. Nevertheless, there is ample evidence that encephalopathy is an independent predictor of mortality. Factors associated with encephalopathy include primary cerebral disorders such as stroke, trauma, and meningitis, or systemic derangements including sepsis, organ failure, and exposure to pharmacological agents and toxins. Although encephalopathy may resolve with treatment of the underlying disorder, there is mounting evidence that cerebral dysfunction persists beyond the acute phase of critical illness. ICU survivors often suffer chronic impairments in cognitive ability, suggesting occult brain injury. The pathogenesis and natural history of encephalopathy, still poorly understood, need further clarification to spur the development of effective preventive and therapeutic interventions.

Is Anaemia a Risk Factor for Delirium in an Acute Geriatric Population?

BACKGROUND/OBJECTIVE

Delirium is a common clinical problem in elderly patients. We aim to investigate whether anaemia is a risk factor for delirium in a hospitalized geriatric population.

METHODS

During a 5-month prospective study, we investigated 190 elderly patients aged 70 years and older with a baseline Mini-Mental State Examination (short version), Confusion Assessment Method, demographic, clinical and laboratory data.

RESULTS

Thirty-four patients were identified as delirious and 95 as anaemic according to the WHO criteria. Stepwise logistic regression revealed that anaemia (haemoglobin level <12 g/l in women and <13 g/l in men), male sex and a diagnosis of dementia were independent risk factors for delirium in the total study group. After adjustment for sex, age, diagnosis of dementia and dehydration, the odds ratio (OR) for anaemia (2.4; 95 CI = 1.02-5.54) remained significantly associated with delirium. When the study population was classified in groups according to sex, anaemia remained a significant risk factor for delirium in men (OR = 3.7; 95% CI = 1.03-15.6) after adjustment for the multiple variables but not in women (OR = 1.54; 95% CI = 0.48-4.9). When the haemoglobin levels were stratified into sex-specific quartiles, the adjusted OR for delirium for men with a haemoglobin level less than 11.1 g/dl was 13.1 (95% CI = 1.17-146).

CONCLUSION

Anaemia is an independent risk factor for delirium and adds valuable information to previously validated predictive models in men but not in women and lower haemoglobin levels were associated with higher risk levels.

Traumatic injury in the older adult from head to toe

This review demonstrates essential issues to consider when caring for older trauma patients, including baseline physical status, mental health, comorbidities, and risk factors for sequelae and future injuries. The impact of a traumatic injury on older adults is complex. Issues of normal aging, functional status, chronic health conditions, and response to treatment affect health care and related decisions. Studies that have examined outcomes for older trauma patients to date have been mainly descriptive or confined to a single institution, limiting our ability to generalize. Other studies, using large data sets, have provided some information regarding possible primary prevention strategies, yet have limitations in the individual level detail collected. Nevertheless, this review also demonstrates the dearth of available evidence-based recommendations that provides support to treatment protocols in this complex and diverse patient population. The lack of an evidence base to use in the management of older trauma patients demonstrates the critical need for research in this rapidly growing population. An example of one such area includes the use of pulmonary artery catheters in older trauma patients. Although evidence to date suggests that pulmonary artery catheters are of benefit in the management of patients with physiologic compromise, it is unclear whether using these published cardiac output management recommendations leads to improved outcomes. In light of newly published data suggesting equivocal benefit from use of pulmonary artery catheters, with increased side effects, this controversy is an important area for future research. Critical care nurses, with their emphasis on multidisciplinary, holistic practice, can expand their influence as essential members of the interdisciplinary team caring for older trauma patients by cultivating geriatric specialty knowledge. Older trauma patients would benefit greatly from this type of specialty nursing care during all phases of the recovery trajectory, particularly in terms of adequate symptom management and prevention of sequelae, as well as with timely and appropriate initiation of consultative services. Using the intersection of primary and secondary prevention as the overall guide for practice, critical care nurses and other health care providers who possess an understanding of aging processes and comorbid conditions can significantly improve outcomes for older adults with traumatic injuries.
