Neuropsychiatric symptom patterns in hospice-eligible nursing home residents with advanced dementia

Neuropsychiatric Manifestations of Cognitively Advanced Idiopathic Normal Pressure Hydrocephalus

Background

Neuropsychiatric manifestations of patients with idiopathic normal pressure hydrocephalus (iNPH) have not been studied in a systematic way.

Aim

To study the spectrum of neuropsychiatric abnormalities in patients with iNPH.

Patient Selection and Evaluation

Patients attending 3 different tertiary care centers during three consecutive time periods spanning from 2010 to 2015 were analyzed for neuropsychiatric manifestations. Patients diagnosed as having probable or possible iNPH as per the consensus criteria were included in the study. Neuropsychiatric manifestations were captured by a comprehensive inventory (Cambridge Behavioral Inventory, CBI).

Results

The CBI score was available for 41 patients. The mean Mini-Mental State Examination score was 15.37 (SD 7.2) and the Addenbrooke's Cognitive Examination score was 34.95 (SD 19.67), thereby indicating cognitively advanced iNPH. All patients had impairment in one or more items on the CBI. The mean score was 55.46 (SD 27) out of 180, thereby indicating a mild degree of impairment. Among the subscores, impairment with motivation was the most observed abnormality followed by memory impairment. When the CBI total score and subscores were compared, all of them (except motivation) were higher for Alzheimer's disease; however, none was statistically significant. Even though the motivation score was higher for iNPH, the difference did not reach statistical significance.

Conclusions

It can be concluded that neurobehavioral abnormalities are common in patients with cognitively advanced normal pressure hydrocephalus. However, the intensity of involvement appeared less when compared to Alzheimer's disease. Apathy appears to be the most common impairment.

Multisensory Stimulation as an Intervention Strategy for Elderly Patients With Severe Dementia: A Pilot Randomized Controlled Trial

The objective of this study was to compare the effect of multisensory stimulation environment (MSSE) and one-to-one activity sessions in the symptomatology of elderly individuals with severe dementia. Thirty-two participants were randomly assigned to the following 3 groups: MSSE, activity, and control group. The MSSE and activity groups participated in two 30-minute weekly sessions over 16 weeks. Pre-, mid-, and posttrial; 8-week follow-up behavior; mood; cognitive status; and dementia severity were registered. Patients in the MSSE group demonstrated a significant improvement in the Neuropsychiatric Inventory and Bedford Alzheimer Nursing Severity Scale scores compared with the activity group. Both MSSE and activity groups showed an improvement during the intervention in the Cohen-Mansfield Agitation Inventory aggressive behavior factor and total score, with no significant differences between groups. The MSSE may have better effects on neuropsychiatric symptoms and dementia severity in comparison with one-to-one activity sessions in patients with severe dementia.

Severe Impairment Rating Scale: A Useful and Brief Cognitive Assessment Tool for Advanced Dementia for Nursing Home Residents

To investigate the utility of the Severe Impairment Rating Scale (SIRS) as a cognitive assessment tool among nursing home residents with advanced dementia, we conducted a cross-sectional study of 96 residents in 3 nursing homes with Functional Assessment Staging Test (FAST) stage 6a and above. We compared the discriminatory ability of SIRS with the Chinese version of Mini-Mental State Examination, Abbreviated Mental Test, and Clock Drawing Test. Among the cognitive tests, SIRS showed the least "floor" effect and had the best capacity to distinguish very severe (FAST stages 7d-f) dementia (area under the curve 0.80 vs 0.46-0.76 for the other tools). The SIRS had the best correlation with FAST staging (r = -.59, P < .01) and, unlike the other 3 tools, exhibited only minimal change in correlation when adjusted for education and ethnicity. Our results support the utility of SIRS as a brief cognitive assessment tool for advanced dementia in the nursing home setting.

Are there differences in the prevalence of palliative care-related problems in people living with advanced cancer and eight non-cancer conditions? A systematic review

CONTEXT

If access to effective palliative care is to extend beyond cancer patients, an understanding of the comparative prevalence of palliative care problems among cancer and non-cancer patients is necessary.

OBJECTIVES

This systematic review aimed to describe and compare the prevalence of seventeen palliative care-related problems across the four palliative care domains among adults with advanced cancer, acquired immune deficiency syndrome, chronic heart failure, end-stage renal disease (ESRD), chronic obstructive pulmonary disease, multiple sclerosis, motor neuron disease, Parkinson's disease, and dementia.

METHODS

Three databases were searched using three groups of keywords. The results of the extraction of the prevalence figures were summarized.

RESULTS

The electronic searches yielded 4697 hits after the removal of 1784 duplicates. Of these hits, 143 met the review criteria. The greatest number of studies were found for advanced cancer (n=57) and ESRD patients (n=47), and 75 of the 143 studies used validated scales. Few data were available for people living with multiple sclerosis (n=2) and motor neuron disease (n=3). The problems with a prevalence of 50% or more found across most of the nine studied diagnostic groups were: pain, fatigue, anorexia, dyspnea, and worry.

CONCLUSION

There are commonalities in the prevalence of problems across cancer and non-cancer patients, highlighting the need for palliative care to be provided irrespective of diagnosis. The methodological heterogeneity across the studies and the lack of non-cancer studies need to be addressed in future research.

The club concept: targeting behavioral issues in a residential setting for cognitively impaired adults

Behavior and psychological symptoms of dementia are common in residential care facilities. These symptoms not only detract from the quality of life of the resident with dementia, but they can be disruptive to the unit and result in harm to staff and other residents. With the trend away from pharmacological management, other creative psychosocial-environmental strategies are being explored. One innovative approach involves the use of the club concept, where selected agitated residents spend a portion of the day in a separate structured environment. This program combines trained staff and tailored activities that optimize mental stimulation, functional independence, and self-esteem. Benefits include reduced incidents of aggressive behaviors and use of psychoactive medications, as well as enhanced quality of life. Not only do the participants benefit from time spent in this specialized setting, but the therapeutic milieu of the facility is also enhanced. Further evaluation of such strategies is needed to quantify the benefits of targeted behavioral interventions for those with cognitive impairment.

Managing dementia agitation in residential aged care

Agitation is a widespread and challenging problem among aged care residents with dementia. This article draws on empirical and theoretical literature to propose a model for preventing and treating agitation non-pharmacologically. A literature review finds agreed, coherent definition and measurement of agitation to be absent despite numerous agitation remedies having been suggested, yet sufficient material to support evidence-based care planning. Agitation is revealed as resulting from a resident’s interactions with the environment or their internal state, giving rise to unmet needs that attentive care can treat. Agitation treatments are reviewed to find no single effective remedy and a lack of quality evaluation. A higher-order, problem-solving approach is proposed. The described system consists of sequential diagnosis, decision making and treatment options, commencing with individualized and institutional preventative measures removing environmental triggers, followed by individual remediation, with residents’ unmet needs receiving priority consistent with patient-centred care.

The clinical course of advanced dementia

BACKGROUND

Dementia is a leading cause of death in the United States but is underrecognized as a terminal illness. The clinical course of nursing home residents with advanced dementia has not been well described.

METHODS

We followed 323 nursing home residents with advanced dementia and their health care proxies for 18 months in 22 nursing homes. Data were collected to characterize the residents' survival, clinical complications, symptoms, and treatments and to determine the proxies' understanding of the residents' prognosis and the clinical complications expected in patients with advanced dementia.

RESULTS

Over a period of 18 months, 54.8% of the residents died. The probability of pneumonia was 41.1%; a febrile episode, 52.6%; and an eating problem, 85.8%. After adjustment for age, sex, and disease duration, the 6-month mortality rate for residents who had pneumonia was 46.7%; a febrile episode, 44.5%; and an eating problem, 38.6%. Distressing symptoms, including dyspnea (46.0%) and pain (39.1%), were common. In the last 3 months of life, 40.7% of residents underwent at least one burdensome intervention (hospitalization, emergency room visit, parenteral therapy, or tube feeding). Residents whose proxies had an understanding of the poor prognosis and clinical complications expected in advanced dementia were much less likely to have burdensome interventions in the last 3 months of life than were residents whose proxies did not have this understanding (adjusted odds ratio, 0.12; 95% confidence interval, 0.04 to 0.37).

CONCLUSIONS

Pneumonia, febrile episodes, and eating problems are frequent complications in patients with advanced dementia, and these complications are associated with high 6-month mortality rates. Distressing symptoms and burdensome interventions are also common among such patients. Patients with health care proxies who have an understanding of the prognosis and clinical course are likely to receive less aggressive care near the end of life.

Research on treating neuropsychiatric symptoms of advanced dementia with non-pharmacological strategies, 1998-2008: a systematic literature review

BACKGROUND

Advanced dementia is characterized by severe cognitive and functional impairments that lead to almost total dependency in self-care. Neuropsychiatric symptoms (NPS) are common in advanced dementia, diminishing quality of life and increasing the care burden. The challenge for health care providers is to find safe and effective treatments. Non-pharmacological interventions offer the potential for safer alternatives to pharmacotherapy, but little is known about their efficacy. This review evaluates the published literature on non-pharmacological interventions for treating NPS in advanced dementia.

METHODS

A literature search was undertaken to find non-pharmacological intervention studies published between 1998 and 2008 that measured NPS outcomes in individuals diagnosed with advanced dementia. Strict inclusion criteria initially required that all study participants have severe or very severe dementia, but this range was later broadened to include moderately severe to very severe stages.

RESULTS

Out of 215 intervention studies, 21 (9.8%) specifically focused on treatments for individuals with moderately severe to very severe dementia. The studies provide limited moderate to high quality evidence for the use of sensory-focused strategies, including aroma, preferred or live music, and multi-sensory stimulation. Emotion-oriented approaches, such as simulated presence may be more effective for individuals with preserved verbal interactive capacity.

CONCLUSIONS

Most studies of interventions for dementia-related NPS have focused on individuals with mild to moderate cognitive impairment. Individuals with severe cognitive impairment do not necessarily respond to NPS treatments in the same manner. Future studies should be specifically designed to further explore the stage-specific efficacy of non-pharmacological therapies for patients with advanced dementia. Areas of particular need for further research include movement-based therapies, hands-on (touch) therapies, and interventions that can be provided during personal care routines. Interventions appear to work best when they are tailored to balance individual arousal patterns.

[Delirium in the elderly]

Delirium is a common, serious medical and often life-threatening condition in elderly in-patients. Delirium can develop primarily or secondarily related to other medical conditions and lead to hospital admission. The pathogenesis is still not fully known and is usually addressed as multifactorial. Alterations in neurotransmitters have a key role in this process. The incidence varies by setting up to 90%. Delirium is associated with increased short- and long-term mortality, iatrogenic complications, functional decline, and future development of cognitive impairment or dementia. Delirium is also associated with longer hospital stays, higher hospital and total health system costs, and an increasing rate of nursing home admissions. A structured diagnostic and therapeutic process is recommended. Delirium should become a quality indicator for hospital medicine; however, many research questions still exist.

Prevalence and treatment of neuropsychiatric symptoms in advanced dementia

Neuropsychiatric symptoms (NPS) are common in dementia, although little is known about their prevalence and treatment near the end of life. This study used a retrospective review of the medical records of 123 hospice-eligible nursing home residents with advanced dementia to investigate the prevalence of NPS and NPS-targeted pharmacological and non-pharmacological treatments. The most prevalent NPS were agitation or aggression (50.4%), depression (45.5%), and withdrawal/lethargy (43.1%). Of the 105 (85.4%) residents who exhibited one or more NPS, 90.5% were receiving at least one NPS-targeted treatment, yet 41.9% received no documented nonpharmacological NPS-targeted care. The majority of documented nonpharmacological care focused on safety and explanations or instructions given to residents. Given the high prevalence of comorbidities, associated risks for medication interactions or serious side effects, and potential low-risk benefits of psychobehavioral care, these findings raise concerns about how to best increase the provision and documentation of nonpharmacological care in advanced dementia.
