Development and psychometric properties of the family distress in advanced dementia scale

Systematic review following COSMIN guidelines: Short forms of Zarit Burden Interview

This comprehensive review assessed the psychometric properties of abbreviated versions of the Caregiver Burden Instrument (ZBI-22). Initially, 40 articles that met the inclusion criteria were identified through a systematic search of four databases. Additionally, 26 articles were included through manual searches, totaling 66 articles in the analysis. Different versions of instruments measuring caregiver burden were examined, considering item variability and differences in factor structures. Although most measures exhibited satisfactory content validity, as well as construct validity supported by high internal consistencies, it is important to note that measurement invariance, criterion validity and test-retest reliability were not established for all measures analyzed. Furthermore, structural validity was not satisfactory for all versions. Research and clinical practice could benefit from a standardized approach that allows for a more accurate and consistent assessment of caregiver strain.

Increase in blood pressure precedes distress behavior in nursing home residents with dementia

BACKGROUND

Distress behaviors in dementia (DBD) likely increase sympathetic nervous system activity. The aim of this study was to examine the associations among DBD, blood pressure (BP), and intensity of antihypertensive treatment, in nursing home (NH) residents with dementia.

METHODS

We identified long-stay Veterans Affairs NH residents with dementia in 2019-20 electronic health data. Each individual with a BP reading and a DBD incident according to a structured behavior note on a calendar day (DBD group) was compared with an individual with a BP reading but without a DBD incident on that same day (comparison group). In each group we calculated daily mean BP from 14 days before to 7 days after the DBD incident day. We then calculated the change in BP between the DBD incident day and, as baseline, the 7-day average of BP 1 week prior, and tested for differences between DBD and comparison groups in a generalized estimating equations multivariate model.

RESULTS

The DBD and comparison groups consisted of 707 and 2328 individuals, respectively. The DBD group was older (74 vs. 72 y), was more likely to have severe cognitive impairment (13% vs. 8%), and had worse physical function scores (15 vs. 13 on 28-point scale). In the DBD group, mean systolic BP on the DBD incident day was 1.6 mmHg higher than baseline (p < .001), a change that was not observed in the comparison group. After adjusting for covariates, residents in the DBD group, but not the comparison group, had increased likelihood of having systolic BP > = 160 mmHg on DBD incident days (OR 1.02; 95%CI 1.00-1.03). Systolic BP in the DBD group began to rise 7 days before the DBD incident day and this rise persisted 1 week after. There were no significant changes in mean number of antihypertensive medications over this time period in either group.

CONCLUSIONS

NH residents with dementia have higher BP when they experience DBD, and BP rises 7 days before the DBD incident. Clinicians should be aware of these findings when deciding intensity of BP treatment.

Palliative care for persons with late-stage Alzheimer's and related dementias and their caregivers: protocol for a randomized clinical trial

BACKGROUND

Limited access to specialized palliative care exposes persons with late-stage Alzheimer's disease and related dementias (ADRD) to burdensome treatment and unnecessary hospitalization and their caregivers to avoidable strain and financial burden. Addressing this unmet need, the purpose of this study was to conduct a randomized clinical trial (RCT) of the ADRD-Palliative Care (ADRD-PC) program.

METHODS

The study will use a multisite, RCT design and will be set in five geographically diverse US hospitals. Lead investigators and outcome assessors will be masked. The study will use 1:1 randomization of patient-caregiver dyads, and sites will enroll N = 424 dyads of hospitalized patients with late-stage ADRD with their family caregivers. Intervention dyads will receive the ADRD-PC program of (1) dementia-specific palliative care, (2) standardized caregiver education, and (3) transitional care. Control dyads will receive publicly available educational material on dementia caregiving. Outcomes will be measured at 30 days (interim) and 60 days post-discharge. The primary outcome will be 60-day hospital transfers, defined as visits to an emergency department or hospitalization ascertained from health record reviews and caregiver interviews (aim 1). Secondary patient-centered outcomes, ascertained from 30- and 60-day health record reviews and caregiver telephone interviews, will be symptom treatment, symptom control, use of community palliative care or hospice, and new nursing home transitions (aim 2). Secondary caregiver-centered outcomes will be communication about prognosis and goals of care, shared decision-making about hospitalization and other treatments, and caregiver distress (aim 3). Analyses will use intention-to-treat, and pre-specified exploratory analyses will examine the effects of sex as a biologic variable and the GDS stage.

DISCUSSION

The study results will determine the efficacy of an intervention that addresses the extraordinary public health impact of late-stage ADRD and suffering due to symptom distress, burdensome treatments, and caregiver strain. While many caregivers prioritize comfort in late-stage ADRD, shared decision-making is rare. Hospitalization creates an opportunity for dementia-specific palliative care, and the study findings will inform care redesign to advance comprehensive dementia-specific palliative care plus transitional care.

Risk factors for agitation in home-cared older adults with dementia: evidence from 640 elders in East China

Background

Agitation is common among older adults with dementia, negatively affecting their quality of life and their caregivers'. Since home care remains the dominant approach for older adults, this study investigates the risk factors for agitation in older adults with dementia in China.

Methods

We perform a cross-sectional study of home-cared older adults with dementia in Ningbo, China, using 2020 data. We use a self-made questionnaire to investigate the risks of agitated behavior and its related factors. We perform descriptive, univariate, and regression analyses.

Findings

We address 640 older Chinese adults; 42.8% of the sample exhibits one or more agitated behaviors. We find that basic health issues, such as activities of daily living (ADL), family support issues, such as Zarit Burden Interview (ZBI) scale and Family APGAR Questionnaire (APGAR), and behavioral awareness issues, such as fall and scald, significantly influence the occurrence of agitation behaviors (p < 0.05). Older adults with severe ADL disorder (b = 6.835, β = 0.196, p < 0.001), ZBI score of 67.00-88.0 (b = 10.212, β = 0.248, p = 0.005), severe APGAR disorder (b = 3.699, β = 0.100, p = 0.012) and a history of fall (b = 9.311, β = 0.199, P = <0.001) or scald (b = 9.288, β = 0.125, p = 0.002) are more likely to exhibit agitated behaviors.

Interpretation

Agitated behavior in home-cared older adults with dementia are diverse and related to mental state, family support, and behavioral awareness issues. Caregivers, often family members, should be attentive to the needs of dementia patients and take active and effective measures to improve their quality of life. They should be aware of the causes and triggers of agitated behavior and take steps to reduce its occurrence.

Caregiver Burden and Dementia: A Systematic Review of Self-Report Instruments

Background: As the demand for dementia care grows rapidly worldwide, heavy “caregiver burden” has been associated with stress and depression. Even so, standard metrics for interdisciplinary research of caregiver burden are limited. Objective: The objective of the present review is to recommend valid, reliable, and comprehensive self-report instruments of caregiver burden. Methods: A systematic review was performed using four databases, searched in April 2021. Articles that established or evaluated self-report instruments for dementia caregiver burden were included, while studies that involved non-dementia caregivers or did not clearly define caregiver burden were excluded. Established guidelines for reliability and agreement studies were used to assess quality and risk of bias. Assessments of self-report instruments were made based on reliability, validity, feasibility, and quality of psychometric evaluations, and comparative evaluations were presented in visual form using radar graphs. Results: Search terms yielded 1,720 articles, and 40 were included in the systematic review after excluding those of low quality. Based on the results of these studies, we recommend the Zarit Burden Interview, Screen for Caregiver Burden, Caregiver Burden Interview, and Burden Scale for Family Caregivers, due to their validity, reliability, and inclusion of multiple subjective and objective dimensions of burden. Conclusion: Targeting specific sources of caregiver burden can help prevent negative outcomes for both dementia patients and caregivers. Future studies should apply self-report instruments to measure and address caregiver burden longitudinally.

Caregiver preparedness for death in dementia: an evaluation of existing tools

Objectives: Death preparedness amongst family caregivers (CG) is a valuable and measurable concept. Preparedness predicts CG outcomes in bereavement and is modifiable through a palliative approach which includes advance care planning (ACP) interventions. Improving death preparedness is important for CGs of persons with dementia (PwD) whom are more likely to develop negative outcomes in bereavement, and experience less than adequate palliative care. However, the adequacy of existing tools to measure death preparedness in CGs of PwD is unknown, which limits intervention design and prospective evaluation of ACP effectiveness.Methods: We conducted a review and evaluation of existing tools measuring the attribute domains and traits of CG death preparedness. Literature was searched for articles describing caregiving at end of life (EOL). Measurement tools were extracted, screened for inclusion criteria, and data extracted regarding: conceptual basis, population of development, and psychometrics. Tool content was compared to preparedness domains/traits to assess congruency and evaluate the adequacy of tools as measures of death preparedness for CGs of PwD.Results: Authors extracted 569 tools from articles, retaining seven tools for evaluation. The majority of tools, n = 5 (70%) did not sample all preparedness domains/traits. Few tools had items specific to EOL; only one tool had a specific item questioning CG preparedness for death, and only one tool had items specific to dementia.Conclusion: Limitations in existing tools suggest they are not adequate measures of death preparedness for CGs of PwD. Consequently, the authors are currently developing a questionnaire to be titled, 'Caring Ahead' for this purpose.

Piloting Me and My Wishes-Videos of Nursing Home Residents' Preferences

CONTEXT

A key challenge in nursing homes (NHs) is how to attain and clarify resident preferences for care and then communicate these preferences to family members and staff.

OBJECTIVES

We evaluated the feasibility and acceptability of Me & My Wishes-person-centered videos of residents discussing their preferences for daily and end-of-life (EOL) care.

METHODS

For this descriptive study, Me & My Wishes videos were created with residents in three NHs in the Pacific Northwest. Feasibility was evaluated by tracking resident enrollment, completing and sharing their video, and conducting debriefing interviews to ascertain residents' impressions of the recording process and personalized conversation. After viewing the video, staff and family assessed communication quality via survey-the extent to which they perceived messages from the video (e.g., preferences for EOL) to be timely, accurate, adequate, complete, and credible and items on resident preferences for daily and EOL care.

RESULTS

Twenty of 33 residents approached created videos; 18 of these residents shared their videos with family or staff. Residents reported that they liked the opportunity to express their wishes. On a scale of 1-7 (lower is better), mean ratings were 2.0 (family) and 1.3 (staff) for communicating preferences for daily care; 1.9 (family) and 1.2 (staff) for communicating preferences for EOL. Both family and staff reported increased knowledge about resident preferences for daily and EOL care.

CONCLUSION

This research supports the feasibility and acceptability of a videotaping approach (Me & My Wishes) for viewing, listening, and discussing residents' preferences for daily and EOL care.

Development of a quality of life questionnaire for nursing home residents in mainland China

OBJECTIVE

To develop and validate a quality of life (QOL) questionnaire for nursing home (NH) residents in mainland China.

METHODS

A cross-sectional study including a development sample (n = 176) and validation sample (n = 371) of NH residents aged 60 and older was conducted between 2015 and 2016 in Jinan, Shandong Province, China. Resident interviews, literature reviews, expert panels, and pilot studies were used to identify QOL domains and items pertinent to NH life. Exploratory and confirmatory factor analysis were used to develop and validate a QOL questionnaire. Reliability (internal consistency, spilt-half reliability, and test-retest reliability) and validity (construct and criterion validity) were evaluated for the questionnaire.

RESULTS

The self-report Chinese NH QOL questionnaire had 9 domains and 38 items including physical health (4 items), food enjoyment (6 items), security (3 items), environmental comfort (5 items), autonomy (2 items), meaningful activity (3 items), interrelationship (6 items), family relationships (3 items), and mood (6 items). The nine-factor model was confirmed with the following fit indices: χ²/df = 1.872, root mean square error of approximation = 0.049, comparative fit index = 0.913, and Tucker-Lewis index = 0.903. The 38-item NH QOL questionnaire showed satisfactory construct validity, criterion validity, internal consistency (Cronbach's alpha = 0.89, spilt-half reliability = 0.73, test-retest reliability = 0.76).

CONCLUSIONS

The NH QOL questionnaire appears to be a reliable and valid instrument and should be incorporated into a set of quality measures for use with NH residents in mainland China.

Triggered Palliative Care for Late-Stage Dementia: A Pilot Randomized Trial

CONTEXT

Persons with late-stage dementia have limited access to palliative care.

OBJECTIVE

The objective of this study was to test dementia-specific specialty palliative care triggered by hospitalization.

METHODS

This pilot randomized controlled trial enrolled 62 dyads of persons with late-stage dementia and family decision-makers on admission to hospital. Intervention dyads received dementia-specific specialty palliative care consultation plus postacute transitional care. Control dyads received usual care and educational information. The primary outcome was 60-day hospital or emergency department visits. Secondary patient- and family-centered outcomes were patient comfort, family distress, palliative care domains addressed in the treatment plan, and access to hospice or community-based palliative care. Secondary decision-making outcomes were discussion of prognosis, goals of care, completion of Medical Orders for Scope of Treatment (MOST), and treatment decisions.

RESULTS

Of 137 eligible dyads, 62 (45%) were enrolled. The intervention proved feasible, with protocol completion ranging from 77% (family two-week call) to 93% (initial consultation). Hospital and emergency department visits did not differ (intervention vs. control, 0.68 vs. 0.53 transfers per 60 days, P = 0.415). Intervention patients had more palliative care domains addressed and were more likely to receive hospice (25% vs. 3%, P < 0.019). Intervention families were more likely to discuss prognosis (90% vs. 3%, P < 0.001) and goals of care (90% vs. 25%, P < 0.001) and to have a MOST at 60-day follow-up (79% vs. 30%, P < 0.001). More intervention families made decisions to avoid rehospitalization (13% vs. 0%, P = 0.033).

CONCLUSION

Specialty palliative care consultation for hospitalized patients with late-stage dementia is feasible and promising to improve decision-making and some treatment outcomes.

Pet robot intervention for people with dementia: A systematic review and meta-analysis of randomized controlled trials

This study aims to systematically evaluate the efficacy of Pet robot intervention (PRI) for people with dementia. Two waves of electronic searches of the PubMed, EMBASE, Web of Science, Cochrane library, IEEE Digital Library and PsycINFO databases were conducted. In total, eight articles from six randomized controlled trials (RCTs) met the eligibility criteria and were included in this systematic review. The results of the meta-analysis showed a statistically significant decrease in behavioral and psychological symptoms of dementia (BPSD), especially agitation and depression, in people with dementia who were treated with PRI. Both individual and group format PRI significantly ameliorated BPSD. However, there were no significant improvements in cognitive function or quality of life. The results of the meta-analysis suggest that PRI may be suitable as a treatment option for BPSD in people with dementia and should be considered as a useful tool in clinical practice.

What Does Death Preparedness Mean for Family Caregivers of Persons With Dementia?

Purpose:

The purpose of this study was to clarify the concept of death preparedness for family caregivers in dementia. Conceptualization was required to support the assessment, promotion, and operationalization (ie, measurement) of death preparedness through palliative care interventions such as advance care planning.

Methods:

Rodgers evolutionary method of concept analysis was selected to guide this study because of the dynamic nature of death preparedness influenced by context, setting, and time. A comprehensive literature search was conducted. Authors performed constant comparative analysis to identify and interpret surrogate/related concepts, attributes, antecedents, and consequences of death preparedness.

Results:

Most importantly attributes included (1) knowing and recognizing the symptoms of decline in dementia and what dying looks like; (2) understanding emotions and grief responses; (3) accessing and appraising supports needed to manage and care for dying; (4) organizing affairs and completing tasks in advance; (5) accepting that losses are inevitable and imminent; (6) reflecting on caregiving and finding meaning, “a silver-lining”; and (7) closing, reconciling, and renewing relationship bonds and completing the family member’s life.

Discussion:

This study contributed a full definition of death preparedness in dementia. Findings aligned with/expanded upon Hebert et al Theoretical Framework of Preparedness for End-of-Life. The use of problem- and emotion-based coping strategies by caregivers with support from health-care providers to promote feelings of death preparedness (including self-efficacy and control) and minimize uncertainty was the implication of this study. Development of a holistic preparedness instrument is underway.

Animal-assisted intervention for individuals with cognitive impairment: A meta-analysis of randomized controlled trials and quasi-randomized controlled trials

The aim of this meta-analysis was to systematically examine the efficacy of animal-assisted intervention (AAI) for cognitive impairment patients. PubMed, Embase, the Cochrane library, PsycINFO, and Web of Science databases were searched up to June 2017 to collect studies related to AAI conducted in patients with cognitive impairment. Five randomized controlled trials (RCTs) and five quasi-randomized controlled trials (quasi-RCTs) involving 413 participants were included. Compared with control groups, AAI groups exhibited significantly fewer behavioral and psychological symptoms of dementia (BPSD), especially depression and agitation. In both the short and long term, AAI had beneficial effects on BPSD in cognitive impairment patients. However, no significant improvements were found in daily living activities, quality of life or cognitive score. The present meta-analysis showed that AAI can be effective in reducing BPSD in patients with cognitive impairment.

Systematic review of systematic reviews of non-pharmacological interventions to treat behavioural disturbances in older patients with dementia. The SENATOR-OnTop series

OBJECTIVE

To provide an overview of non-pharmacological interventions for behavioural and psychological symptoms in dementia (BPSD).

DESIGN

Systematic overview of reviews.

DATA SOURCES

PubMed, EMBASE, Cochrane Database of Systematic Reviews, CINAHL and PsycINFO (2009-March 2015).

ELIGIBILITY CRITERIA

Systematic reviews (SRs) that included at least one comparative study evaluating any non-pharmacological intervention, to treat BPSD.

DATA EXTRACTION

Eligible studies were selected and data extracted independently by 2 reviewers.The AMSTAR checklist was used to assess the quality of the SRs.

DATA ANALYSIS

Extracted data were synthesised using a narrative approach.

RESULTS

38 SRs and 129 primary studies were identified, comprising the following categories of non-pharmacological interventions: (1) sensory stimulation interventions (25 SRs, 66 primary studies) that encompassed: shiatsu and acupressure, aromatherapy, massage/touch therapy, light therapy, sensory garden and horticultural activities, music/dance therapy, dance therapy, snoezelen multisensory stimulation therapy, transcutaneous electrical nerve stimulation; (2) cognitive/emotion-oriented interventions (13 SRs; 26 primary studies) that included cognitive stimulation, reminiscence therapy, validation therapy, simulated presence therapy; (3) behaviour management techniques (6 SRs; 22 primary studies); (4) Multicomponent interventions (3 SR; four primary studies); (5) other therapies (5 SRs, 15 primary studies) comprising exercise therapy, animal-assisted therapy, special care unit and dining room environment-based interventions.

CONCLUSIONS

A large number of non-pharmacological interventions for BPSD were identified. The majority of the studies had great variation in how the same type of intervention was defined and applied, the follow-up duration, the type of outcome measured, usually with modest sample size. Overall, music therapy and behavioural management techniques were effective for reducing BPSD.
