Development of a Psychometric Test: A Care Risk Scale for Homebound Older People With Dementia

Background

Homebound older people with dementia (OPWD) face a series of care risks due to disease characteristics, care issues, and the family environment. However, China lacks a quantitative assessment tool for care risk. Thus, we attempted to develop a care risk scale for homebound OPWD.

Methods

A care risk scale, with initially 18 items, was designed based on a systematic literature review, expert consultation, and a pilot study with 20 OPWD. The initial scale was validated among 1,045 homebound OPWD in Ningbo, China from November 1, 2020 to July 30, 2021. After removing three items that lacked discrimination power, the reliability and validity of the remaining 15 items was evaluated. Factor extraction was performed via principal axis factoring and Cattell's scree plot analysis, with the resulting factors then being subjected to a varimax rotation.

Results

The final scale consisted of 15 items assessed on a 5-point Likert scale that loaded on to three different factors, including dementia symptoms (four items), family support (four items), and home environment (seven items). These three factors were found to explain 72.9% of the cumulative variance. The overall Cronbach's alpha for the final scale was 0.907. The correlation coefficients in the item-to-total analysis ranged from 0.511 to 0.662.

Conclusion

The validation analysis indicated satisfactory reliability and validity of the 15-item scale for assessing care risk of homebound OPWD. This scale can help long-term care professionals and family caregivers identify care risks and help them take targeted measures to enhance safety of care for OPWD.

Vocally disruptive behaviour in nursing home residents in Ireland: a descriptive study

BACKGROUND

Vocally disruptive behaviour (VDB) is relatively common in nursing home residents but difficult to treat. There is limited study on prevalence and treatment of VDB. We hypothesise that VDB is a result of complex interaction between patient factors and environmental contributors.

METHODS

Residents of nursing homes in south Dublin were the target population for this study. Inclusion criteria were that the residents were 65 years or over and exhibited VDB significant enough for consideration in the resident's care plan. Information on typology and frequency of VDB, Interventions employed and their efficacy, diagnoses, Cohen-Mansfield Agitation Inventory scores, Mini-Mental State Examination scores, and Barthel Index scores were obtained.

RESULTS

Eight percent of nursing home residents were reported to display VDB, most commonly screaming (in 39.4% of vocally disruptive residents). VDB was associated with physical agitation and dementia; together, these two factors accounted for almost two-thirds of the variation in VDB between residents. One-to-one attention, engaging in conversation, redirecting behaviour, and use of psychotropic medication were reported by nurses as the most useful interventions. Analgesics were the medications most commonly used (65.7%) followed by quetiapine (62.9%), and these were reportedly effective in 82.6% and 77.2% of residents respectively.

CONCLUSIONS

VDB is common, challenging, and difficult to manage. The study of VDB is limited by a variety of factors that both contribute to this behaviour and make its treatment challenging. Issues relating to capacity and ethics make it difficult to conduct randomised controlled trials of treatments for VDB in the population affected.

Agitation in patients with dementia: a systematic review of epidemiology and association with severity and course

OBJECTIVES

More than 90% of individuals with Alzheimer's disease (AD) experience behavioral and neuropsychiatric symptoms (NPS), such as agitation. However, little is known regarding the specific burden of agitation for Alzheimer's patients.

DESIGN

A global systematic literature review was conducted in MEDLINE and Embase for studies of clinical, humanistic, and economic burden of agitation in AD/dementia published from 2006-2016. References of identified papers and related literature reviews were examined. Studies meeting predetermined inclusion criteria for burden of agitation/NPS were summarized.

RESULTS

Eighty papers met the inclusion criteria for burden of agitation in dementia. Wide ranges of agitation prevalence were reported, but few papers provided information on incidence. The association of agitation with AD severity was presented in multiple studies; a few suggested positive association of agitation with mortality.

CONCLUSIONS

High prevalence of agitation is consistent with earlier reports, but several gaps in understanding of agitation in AD need further exploration.

The course of neuropsychiatric symptoms in nursing home residents from admission to 30-month follow-up

Aim

The aim of this study was to describe the prevalence and persistence of clinically significant neuropsychiatric symptoms (NPS) in nursing home residents with dementia, and to study the association between severity of dementia and specific neuropsychiatric sub-syndromes over time.

Methods

In total, 583 residents with dementia were included at admission to a nursing home and followed with biannual assessments until death, or to 30-month follow-up. At the end of the 30-month follow-up, 305 participants had died and 57 had left the study for other reasons, leaving 221 residents in the study. We collected data on demographics, cognition, severity of dementia, NPS, personal activities of daily living (P-ADL), physical health, medication and type of nursing home unit. NPS was assessed using the Neuropsychiatric Inventory (NPI), the Nursing Home version.

Results

The prevalence and persistence at two consecutive time-points of clinically significant NPS was high during the study period. The mean NPI agitation sub-syndrome score increased during the study period, while the NPI affective and psychosis sub-syndrome scores remained unchanged. More severe dementia was associated with higher NPI agitation, psychosis and affective sub-syndrome scores. The association remained unchanged over time for agitation and psychosis. For the NPI affective sub-syndrome, the association was stronger at the beginning, and declined towards the end of the study period.

Conclusion

The findings of high prevalence and persistence at two consecutive time points of clinically significant NPS over time, and the associations between severity of dementia and NPI sub-syndromes shed light on the burden and care needs of nursing home residents with dementia after admission to nursing home care. This information is of interest to health care planners and providers to enable them to increase the quality of care for nursing home residents.

Longitudinal course of behavioural and psychological symptoms of dementia: systematic review

BACKGROUND

More information about the pattern of behavioural and psychological symptoms of dementia (BPSD) in the course of dementia is needed to inform patients and clinicians and to design future interventions.

AIMS

To determine the persistence and incidence of BPSD and their relation to cognitive function, in individuals with dementia or in cohorts investigated for dementia onset.

METHOD

A systematic literature review analysed the baseline prevalence, persistence and incidence of 11 symptoms. The review was conducted according to established guidelines with the exception that we could not exclude the possibilities of bias in the studies examined.

RESULTS

The 59 included studies showed considerable heterogeneity in their objectives and methods. The symptoms hyperactivity and apathy showed high persistence and incidence; depression and anxiety low or moderate persistence and moderate incidence; and psychotic symptoms low persistence with moderate or low incidence.

CONCLUSIONS

Despite heterogeneity across studies in terms of setting, focus and length of follow-up, there were clinically relevant differences in the longitudinal courses of different BPSD. Apathy was the only symptom with high baseline prevalence, persistence and incidence during the course of dementia.

The relationship between pain and disruptive behaviors in nursing home residents with dementia

Background

Nursing home residents with dementia gradually lose the ability to process information so that they are less likely to express pain in typical ways. These residents may express pain through disruptive behaviors because they cannot appropriately verbalize their pain experience. The objective of this study was to investigate the effect of pain on disruptive behaviors in nursing home residents with dementia.

Methods

This is a secondary analysis of the Minimum Data Set (MDS 2.0) assessment data on long-term care from the state of Florida. The data used in this study were the first comprehensive assessment data from NH residents with dementia aged 65 and older (N = 56,577) in Medicare- or Medicaid-certified nursing homes between January 1, 2009 and December 31, 2009. Variables examined were pain, wandering, aggression, agitation, cognitive impairment, activities of daily living impairments, and demographic characteristics. Ordinal logistic regression was used to evaluate the effect of pain on disruptive behaviors.

Results

Residents with more severe pain are less likely to display wandering behaviors (OR = .77, 95% CI for OR = [0.73, 0.81]), but more likely to display aggressive and agitated behaviors (OR = 1.04, 95% CI for OR = [1.01, 1.08]; OR = 1.17, 95% CI for OR = [1.13, 1.20]).

Conclusions

The relationship between pain and disruptive behaviors depends on the type of behaviors. Pain is positively correlated with disruptive behaviors that do not involve locomotion (e.g., aggression and agitation), but negatively related to disruptive behaviors that are accompanied by locomotion (e.g., wandering). These findings indicate that effective pain management may help to reduce aggression and agitation, and to promote mobility in persons with dementia.

Nursing interventions in cases of agitation and dementia

This study had two objectives: firstly, to assess and compare the frequency and circumstances of agitation and, secondly, to generate decision-making aids for the treatment of agitation patients by applying a nursing intervention in cases of dementia and agitation. For that purpose, 1002 measurements of open nursing interventions in cases of agitation were obtained over a period of 11 weeks in two nursing homes in the city of Zurich and in the nursing home Sonnweid. Before, during and after two intervention periods of four weeks each, data were collected for 60 persons suffering from severe dementia. The results show that two-thirds of the residents were never agitated, one-quarter was moderately agitated and only very few suffered from medium-to-severe agitation. In almost half the cases, agitation occurred while the person was alone (46%), followed by cases of agitation as a constant state (26%). There was rarely any agitation while the residents were engaged in activities. After analysing 433 documented cases, it turned out that the most successful care interventions were avoiding noise, accompanying the person to the toilet, communication/validation, walking about/movement and administering beverages. Being based on newly translated observational methods and a unique longitudinal study design with combined intervention, this study provides important insights into how agitation in dementia can be influenced within the care context, as well as a practical evaluation of interventions specific to different institutions.

Report of an evaluation of a nurse-led dementia outreach service for people with the behavioural and psychological symptoms of dementia living in residential aged care facilities

BACKGROUND

This paper describes the implementation and evaluation of a Dementia Outreach Service (DEMOS). The service is led by the first Nurse Practitioner in Dementia Care in the State of Queensland in Australia and is highly innovative in terms of its mode of delivery. The evaluation took place due to a perception that new models such as the DEMOS often fail to gain momentum due to a lack of data on their effectiveness and efficiency.

METHOD

The parameters of the project were to evaluate the extent to which the DEMOS met its key deliverables, focusing specifically on outcomes for residential aged care facilities (RACF) residents and staff. The study involved both quantitative and qualitative data collection. Qualitative data was collected through interviews, focus groups and reflective journals. A survey which was administered at three stages of the 12 months of the study was the main source of quantitative data. Additional statistical data was collected from relevant healthcare providers.

FINDINGS

Twenty RACFs within a specific health service district participated in the study. This included an intervention group of 7 facilities (which received the service) and a control group of 13. A total of 320 RACF staff participated in Stage 1 of the study, although due to staff attrition this had reduced to 153 (54.6%) at Stage 3. Attrition rates were much lower in the 7 intervention facilities, with 67.9% of the original sample remaining at Stage 3. To augment the quantitative data collected as above, drawing on a range of qualitative techniques the researchers canvassed the perceptions, thoughts and opinions of differing stakeholders. The qualitative data proved extremely valuable in confirming the success of DEMOS. KEY SUCCESS AREAS: Increased self-confidence among staff in dealing with residents with dementia; reduced stress among staff; reductions in the instances of difficult behaviours; reduced referrals to acute sector services; high levels of satisfaction among RACF management regarding DEMOS; and a process of continuous improvement of DEMOS based on stakeholder feedback.

IMPLICATIONS FOR PRACTICE

Recommendations for the future directions of the service include: The continued support and expansion of DEMOS; An increase in the DEMOS service portfolio to actively assist facilities to change the culture of care amongst RACF carers; and Showcasing of DEMOS as an example of 'best practice' in dementia care to argue the need for provision of additional Nurse Practitioners specializing in dementia care.

Factors associated with problematic vocalizations in nursing home residents with dementia

PURPOSE OF THE STUDY

Problematic vocalizations (PVs) are the most frequent and persistent disruptive behaviors exhibited by nursing home residents with dementia. Understanding factors associated with these behaviors are important to prevent or reduce them. We used the Need-Driven Dementia-Compromised Behavior model to identify the characteristics of persons with dementia who are likely to display nonaggressive and aggressive PVs and the conditions under which these behaviors are likely to occur and persist.

DESIGN AND METHODS

This multisite descriptive study included 138 residents of 17 nursing homes, and approximately half had a history of PVs. Background data were gathered through interviews, chart reviews, and administration of physical and neuropsychological assessments. Proximal data were obtained from observations and videotapes.

RESULTS

When the 2 subscales of the Verbal Behavior Scale were used as the dependent variables, agreeableness and conscientiousness, positive affect, and discomfort were associated with nonaggressive vocalizations, and general health state (GHS), age, and negative and positive affect were associated with aggressive vocalizations. When the verbally agitated (nonaggressive) section of the Cohen-Mansfield Agitation Inventory was the dependent variable, the background factors of gender, agreeableness, GHS, and age remained predictors, as did the proximal factors of affect and discomfort.

IMPLICATIONS

We identified 5 background factors and 3 proximal factors as risk factors for PVs in persons with dementia, with variation between nonaggressive or aggressive PVs. These data provide direction for caregiving for persons with dementia and design of interventions to prevent or reduce PVs.

Auditory Dysfunction in Alzheimer's Disease

Alzheimer's disease is neurodegenerative disorder which affects a growing number of older adults every year. With an understanding of auditory dysfunction in Alzheimer's disease, the speech-language pathologist working in the health care setting can provide better service to these individuals. The pathophysiology of the disease process in Alzheimer's disease increases the likelihood of specific types of auditory deficits as opposed to others. This article will discuss the auditory deficits in Alzheimer's disease, their implications, and the value of clinical protocols for individuals with this disease.

The efficacy of nurse implemented non-pharmacological strategies for the symptom management of agitation in persons with advanced dementia living in residential aged care facilities: a systematic review

AIM

Agitation is a common symptom of dementia which becomes exacerbated in the advanced stages of the disease. The negative effects of this symptom are numerous and often result in institutionalisation. Given it is the registered nurse, with the cooperation of the enrolled nurse/ assistant in nursing, who provide the majority of face-to-face care in residential aged care facilities, there is a clear need to identify effective management strategies for agitated behaviours which nursing staff can easily access and implement.This review identifies the best available evidence regarding the efficacy of nurse implemented non-pharmacological strategies for the symptom management of agitation in persons with advanced dementia living in residential aged care facilities METHOD: A systematic literature search of MEDLINE, CINAHL, PsycINFO, Cochrane Library, SCOPUS, EMBASE, and AgeLine databases was undertaken. Additionally, the reference lists of relevant papers were examined for additional trials.This review considered any English language randomised trial that investigated strategies implemented by a nurse for the symptom management of agitation in persons with advanced dementia living in residential aged care facilities. Outcomes measured included frequency and severity of agitation.

RESULTS

Seven trials were included in this review. Five of the seven strategies investigated were shown to be effective in the symptom management of agitation when compared to alternate strategies. Effective strategies include: behavioural therapy, balancing arousal states, therapeutic touch, multi-sensory stimulation and person-centred bathing.

CONCLUSIONS

The heterogeneity of the included trials made it difficult to draw definitive conclusion. However, the results of this systematic review reveal that some non-pharmacological strategies are effective when implemented by a nurse for the symptom management of agitation in pesons with advanced dementia living in residential aged care facilities. Despite this finding, there is currently insufficient evidence to develop practice guidelines.

The course of psychiatric and behavioral symptoms and the use of psychotropic medication in patients with dementia in Norwegian nursing homes--a 12-month follow-up study

OBJECTIVE

This study investigates the natural course of neuropsychiatric symptoms and the concomitant use of psychotropic medication among a large and representative sample of nursing-home patients with dementia.

METHOD

The authors performed two data collections with structured interviews in a 1-year follow-up cohort-study including 26 nursing homes in four counties in two Norwegian health regions. The main outcome measures were baseline and follow-up frequencies, persistence and incidence of neuropsychiatric symptoms, and the change in neuropsychiatric symptoms with regard to the use of psychotropic medication.

RESULTS

At baseline a representative sample of 1,163 nursing-home patients participated, of whom 933 had dementia. At the follow-up interview after 1 year, 633 of the patients who had dementia at baseline were assessed. Clinically significant neuropsychiatric symptoms were exhibited by 84% of patients with dementia at the baseline or follow-up interviews. Overall persistence of symptoms was 79%. Individual symptoms, such as depression (58%), delusions (56%), and agitation/aggression (47%) had resolved at a high rate. Persistent use of antidepressants (79%), antipsychotics (75%), or any psychotropic drug (88%) was common. There were no differences between users and nonusers of antipsychotics or antidepressants regarding the course of psychosis, agitation, or depression over the 1-year observation period.

CONCLUSION

Neuropsychiatric symptoms are ubiquitous in nursing home patients with dementia. Overall the symptoms are chronically present, whereas individual symptoms often show an intermittent course. Long-term use of psychotropic medication is extensive. Uncertainty about treatment effects emphasizes the need for further treatment trials.
