Predictors of long-term care placement in persons with dementia: a systematic review and meta-analysis

Predictors of Cholinesterase Discontinuation during the First Year after Nursing Home Admission

OBJECTIVES

For persons with dementia, the appropriate duration of cholinesterase inhibitor (ChEI) use remains unclear. We examined patterns of ChEI use during nursing home (NH) transition and the factors associated with discontinuation following admission.

DESIGN

Population-based retrospective cohort study using linked health administrative and Resident Assessment Instrument Minimum Dataset, version 2.0 databases.

SETTING AND PARTICIPANTS

A total of 47,851 older adults (mean age = 84.8 years, standard deviation = 6.8) with dementia newly admitted to a NH in Ontario, Canada between 2011 and 2015.

MEASUREMENTS

ChEI use at admission and during the following year was identified from prescription claims. Resident sociodemographic and health characteristics at admission, including a 72-item frailty index, were derived from the Resident Assessment Instrument Minimum Dataset 2.0. Additional resident and prescriber characteristics were derived from administrative data. Discontinuation was defined as a 30+-day gap in ChEI supply. Multivariable subdistribution hazard models were used to estimate the independent effect of resident frailty and other factors on ChEI discontinuation.

RESULTS

Approximately one-third (17,560) of residents with dementia were on a ChEI at admission. Among this group, 17.7% (3110) discontinued use over follow-up. Incidence of discontinuation was significantly higher among residents with syncope [subdistribution hazard ratio, sHR = 2.21, 95% confidence interval, CI (1.52, 3.22)], more severe behavioral symptoms [sHR = 1.79, 95% CI (1.57, 2.05)], cognitive impairment [sHR = 1.26, 95% CI (1.07, 1.48)], higher frailty, [sHR = 1.19, 95% CI (1.04, 1.36)], and a primary prescriber active in the NH [sHR = 1.28, 95% CI (1.14, 1.45)]. A significantly lower incidence was observed for older and unmarried residents and those with a longer duration of use.

CONCLUSIONS/IMPLICATIONS

Less than one-fifth of residents on a ChEI at admission discontinued use during the following year. Although some of the predictors of discontinuation align with past research and current clinical recommendations, others were unexpected and point to novel drivers of ChEI use. Future investigations should explore the varied reasons underlying these associations and resident outcomes associated with ChEI discontinuation.

Variation in the health outcomes associated with frailty among home care clients: relevance of caregiver distress and client sex

Background

The identification of contextual factors that modify associations between client frailty and their health and service use outcomes is essential for informed home health care and policy planning. Our objective was to examine variation in the associations between frailty and select 1-year health outcomes by caregiver distress and client sex among community-residing older care recipients.

Methods

We conducted a retrospective cohort study using linked population-based clinical and health administrative databases for all long-stay home care clients (n = 234,552) aged 66+ years assessed during April 2010–2013 in Ontario, Canada. Frailty was assessed using a previously validated 72-item frailty index (FI). Presence of caregiver distress was derived from clinical assessment items administered by trained home care assessors. Multivariable log-binomial regression models were used to examine variations in the associations between frailty and outcomes of interest (mortality, nursing home [NH] placement, all-cause and prolonged hospitalization) by caregiver distress, with further model stratification by client sex.

Results

Frailty prevalence varied little by sex (19.3% women, 19.9% men) despite significant sex-differences in clients’ sociodemographic and health characteristics. In both sexes, frailty was significantly associated with all outcomes, particularly NH placement (RR = 3.84, 95%CI 3.75–3.93) and death (RR = 2.32, 95%CI 2.27–2.37), though risk ratios were greater for women. Caregiver distress was more common with increasing frailty and for male clients, and a significant independent predictor of NH placement and prolonged hospitalization in both sexes. The association between frailty and NH placement (but not other outcomes) varied by caregiver distress for both men and women (p < 0.001 interaction terms), showing a greater magnitude of association among clients without (vs. with) a distressed caregiver.

Conclusions

As caregiver distress varies by client sex, represents a key driver of NH placement (even among relatively robust clients), and modifies the impact of other risk factors such as frailty, it should be routinely assessed. Further, sex-differences should be considered when developing and evaluating community-based services for older adults and their caregivers.

"Please listen to me": A cross-sectional study of experiences of seniors and their caregivers making housing decisions

BACKGROUND

Little is known about the decision-making experiences of seniors and informal caregivers facing decisions about seniors' housing decisions when objective decision making measures are used.

OBJECTIVES

To report on seniors' and caregivers' experiences of housing decisions.

DESIGN

A cross-sectional study with a quantitative approach supplemented by qualitative data.

SETTING

Sixteen health jurisdictions providing home care services, Quebec province, Canada.

PARTICIPANTS

Two separate samples of seniors aged ≥ 65 years and informal caregivers of cognitively impaired seniors who had made a decision about housing.

MEASUREMENTS

Information on preferred choice and actual choice about housing, role assumed in the decision, decisional conflict and decision regret was obtained through closed-ended questionnaires. Research assistants paraphrased participants' narratives about their decision-making experiences and made other observations in standardized logbooks.

RESULTS

Thirty-one seniors (median age: 85.5 years) and 48 caregivers (median age: 65.1 years) were recruited. Both seniors and caregivers preferred that the senior stay at home (64.5% and 71.7% respectively). Staying home was the actual choice for only 32.2% of participating seniors and 36.2% of the seniors cared for by the participating caregivers. Overall, 93% seniors and 71% caregivers reported taking an active or collaborative role in the decision-making process. The median decisional conflict score was 23/100 for seniors and 30/100 for caregivers. The median decision regret score was the same for both (10/100). Qualitative analysis revealed that the housing decision was influenced by factors such as seniors' health and safety concerns and caregivers' burden of care. Some caregivers felt sad and guilty when the decision did not match the senior's preference.

CONCLUSION

The actual housing decision made for seniors frequently did not match their preferred housing option. Advanced care planning regarding housing and better decision support are needed for these difficult decisions.

Entitlement of carer's allowance to support home care of persons with Alzheimer's disease: evaluation of current decision criteria

PURPOSE

Several countries support family caregivers (FCs) by means of an informal carer's allowance (CA). In this study, we aimed to examine CA entitlement in association with clinical factors related to persons with Alzheimer's disease (AD) and their FCs, provided psychosocial rehabilitation, and the Morbidity index designed to measure regional variations in morbidity and burden.

METHODS

A total of 236 FCs and 236 care recipients (CRs) with AD participated in this prospective longitudinal 5-year follow-up study (ALSOVA). We used generalized estimating equation models to investigate the associations between granting CA and repeated measurements of socioeconomic and clinical characteristics.

RESULTS

Over 5 years of caregiving, CAs were granted to only 18% of the FCs. CA receipt was significantly associated with the CR having decreased activities of daily living (lower ADCS-ADL, p ≤ 0.001, OR 0.93, 95% CI 0.92-0.94) and increased disease severity (lower Clinical Dementia Rating-Sum of Boxes, p ≤ 0.001, OR 1.40, 95% CI 1.30-1.50). In addition, CAs were more commonly granted in municipalities with higher morbidity rates (p = 0.010, OR 1.03, 95% CI 1.01-1.05), and a 1-year increase in FC age was associated with a 4% increase in the odds of CA receipt (OR 1.04, 95% CI 1.01-1.07).

CONCLUSIONS

CA receipt was influenced by increased dependency (measured by ADCS-ADL) and disease severity of persons with AD. FCs more commonly received CAs in municipalities with older and less-healthy populations. These findings verified that informal care is supported in accordance with international recommendations.

Tele-Savvy: An Online Program for Dementia Caregivers

INTRODUCTION

This study examined the feasibility and efficacy of Tele-Savvy, an online version of the Savvy Caregiver Program, a psychoeducation program for caregivers caring for a person with dementia.

METHODS

A convenience sample of 22 caregivers from the Atlanta VA and 42 caregivers from 14 different states enrolled in Tele-Savvy. Pre- and post-program evaluations assessed caregiver burden, caregiver competency, and frequency of behavioral and psychological symptoms of dementia (BPSD).

RESULTS

Fifty-seven caregivers completed the 6-week Tele-Savvy program. Caregivers whose care recipients exhibited higher average BPSD frequency at baseline demonstrated significantly greater burden decreases post-program. Caregivers of care recipients in more advanced dementia stages demonstrated a significantly greater improvement in caregiver competence.

DISCUSSION

The results point to the feasibility of achieving significant results in caregivers' well-being and care recipients' BPSD with a fully online program. Tele-Savvy may be particularly efficacious for caregivers whose care recipients exhibit higher BPSD frequency and are in later dementia stages.

Income-based inequalities in caregiving time and depressive symptoms among older family caregivers under the Japanese long-term care insurance system: A cross-sectional analysis

AIM

Long-term care systems may alleviate caregiver burdens, particularly for those with fewer resources. However, it remains unclear whether socioeconomic disparity in caregiver burdens exists under a public, universal long-term care insurance (LTCI) system. This study examined income-based inequalities in caregiving time and depressive symptoms in Japanese older family caregivers. We further compared inequality in depressive symptoms with that of non-caregivers to evaluate whether family caregiving exacerbates this disparity.

METHODS

Data were obtained from a cross-sectional, nationwide survey conducted by the Japan Gerontological Evaluation Study in 2013. Participants were functionally independent older adults aged ≥65 years (N = 21,584). Depressive symptoms were assessed using the Geriatrics Depression Scale (GDS); caregiving hours per week, household income, and other covariates were also assessed.

RESULTS

Family caregivers occupied 8.3% of the total. A Poisson regression model revealed that caregivers in lower income groups (compared to those in the highest) were 1.32 to 1.95 and 1.63 to 2.68 times more likely to engage in ≥36 and ≥72 hours/week of caregiving, respectively. As for the GDS (≥5), an excess risk was found in the caregivers in lower (compared to higher) income groups (adjusted prevalence ratio: 1.57-3.10). However, an interaction effect of income by caregiving role indicated no significant difference in inequality between caregivers and non-caregivers (p = .603). The excess risk for GDS (≥5) in the caregivers compared to non-caregivers was observed across income groups.

CONCLUSIONS

Our findings revealed a possible disparity in family caregivers under the public LTCI system. Further studies should examine factors associated with longer caregiving hours in lower income households. Our findings also suggest the necessity for more efforts to alleviate depressive symptoms in family caregivers under the LTCI system regardless of income level, rather than exclusively supporting those with a low income.

Benefits of Occupational Therapy in Dementia Patients: Findings from a Real-World Observational Study

BACKGROUND

There is a growing interest in developing non-pharmacological approaches in dementia. Clinical efficacy of occupational therapy (OT) under routine care conditions has not been investigated yet.

OBJECTIVE

To analyze the short-term effects of OT in patients with dementia; and to identify factors related to greater benefit.

METHODS

Patients referred to OT were evaluated before starting a 3-month intervention and at 3 and 6 months later. Measures included: Mini-Mental State Examination (MMSE), Disability Assessment in Dementia (DAD), Neuropsychiatric Inventory (NPI) Questionnaire, patients' quality of life (EQ 5D-VAS), caregivers' burden (Zarit scale), and amount of informal care. Linear mixed models were used to analyze trajectories of outcomes. Logistic regressions with stepwise descending selection were used to study factors associated with benefits.

RESULTS

421 dementia patients benefited from OT (mean MMSE = 17.3). Patients remained cognitively stable over time. Functional performances also remained stable at 3 months and significantly decreased at 6 months (crude reduction of 2.8 points, p < 0.01). Behavioral troubles were significantly reduced over the intervention period and remained stable after (p < 0.01). Patients' quality of life increased over the 3-month intervention (p = 0.16) and significantly decreased thereafter. Caregivers' burden and informal care significantly decreased over the 3-month intervention and remained stable thereafter. Patients who benefited from OT with regard to function were less educated and had higher cognitive level.

CONCLUSION

OT may be an effective intervention to maintain cognition and functionality and to reduce psychiatric symptoms in dementia patients. Mild stages of dementia could gain more benefits from OT with regard to functional decline.

Policy choices in dementia care-An exploratory analysis of the Alberta continuing care system (ACCS) using system dynamics

BACKGROUND

The increase in the incidence of dementia in the aging population and the decrease in the availability of informal caregivers put pressure on continuing care systems to care for a growing number of people with disabilities. Policy changes in the continuing care system need to address this shift in the population structure. One of the most effective tools for assessing policies in complex systems is system dynamics. Nevertheless, this method is underused in continuing care capacity planning.

METHODS

A system dynamics model of the Alberta Continuing Care System was developed using stylized data. Sensitivity analyses and policy evaluations were conducted to demonstrate the use of system dynamics modelling in this area of public health planning. We focused our policy exploration on introducing staff/resident benchmarks in both supportive living and long-term care (LTC).

RESULTS

The sensitivity analyses presented in this paper help identify leverage points in the system that need to be acknowledged when policy decisions are made. Our policy explorations showed that the deficits of staff increase dramatically when benchmarks are introduced, as expected, but at the end of the simulation period, the difference in deficits of both nurses and health care aids are similar between the 2 scenarios tested. Modifying the benchmarks in LTC only versus in both supportive living and LTC has similar effects on staff deficits in long term, under the assumptions of this particular model.

CONCLUSION

The continuing care system dynamics model can be used to test various policy scenarios, allowing decision makers to visualize the effect of a certain policy choice on different system variables and to compare different policy options. Our exploration illustrates the use of system dynamics models for policy making in complex health care systems.

Predictors of institutionalization in people with dementia: a survey linked with administrative data

BACKGROUND

For people with dementia, moving into a nursing home is usually considered at some point in time. Currently available information on predictors of institutionalization is often based on small sample sizes, not taking competing risks into account, and with inconclusive results for sex.

AIMS

We aimed to carry out an analysis stratified by sex and using a competing risk approach.

METHODS

We carried out an analysis of a survey linked with administrative data including 652 people with dementia, aged 60 years and older. The follow-up was up to 4.5 years. We used the cumulative incidence function for examining time until institutionalization and survival time and the sub-distribution hazard model for estimating hazard ratios.

RESULTS

The participants were on average 81 years old, about 51% were female. At the end of the follow-up, 282 people had been institutionalized and 273 had died. The regression models show that the risk of institutionalization is higher in women than in men and when cared for by a care service in comparison to an informal caregiver. Inhibiting factors are Care Level (II, III) and positive evaluation of caregiving by caregivers. Stratified analysis by sex revealed that the risk of institutionalization in men is influenced by their relationship to their caregiver, in women by duration of care at baseline.

DISCUSSION

Sex seems to play a role in predicting institutionalization.

CONCLUSION

Future research should focus on stratified analysis by sex. Knowing the predictors of institutionalization for men and women could influence long-term care management remarkably.

Deciding How to Stay Independent at Home in Later Years: Development and Acceptability Testing of an Informative Web-Based Module

Background

Seniors with loss of autonomy may face decisions about whether they should stay at home or move elsewhere. Most seniors would prefer to stay home and be independent for as long as possible, but most are unaware of options that would make this possible.

Objective

The study aimed to develop and test the acceptability of an interactive website for seniors, their caregivers, and health professionals with short interlinked videos presenting information about options for staying independent at home.

Methods

The approach for design and data collection varied, involving a multipronged, user-centered design of the development process, qualitative interviews, and end-user feedback to determine content (ie, needs assessment) in phase I; module development (in English and French) in phase II; and survey to test usability and acceptability with end users in phase III. Phase I participants were a convenience sample of end users, that is, seniors, caregivers, and professionals with expertise in modifiable factors (eg, day centers, home redesign, equipment, community activities, and finances), enabling seniors to stay independent at home for longer in Quebec and Alberta, Canada. Phase II participants were bilingual actors; phase III participants included phase I participants and new participants recruited through snowballing. Qualitative interviews were thematically analyzed in phase II to determine relevant topics for the video-scripts, which were user-checked by interview participants. In phase III, the results of a usability questionnaire were analyzed using descriptive statistics.

Results

In phase I, interviews with 29 stakeholders, including 4 seniors, 3 caregivers, and 22 professionals, showed a need for a one-stop information resource about options for staying independent at home. They raised issues relating to 6 categories: cognitive autonomy, psychological or mental well-being, functional autonomy, social autonomy, financial autonomy, and people involved. A script was developed and evaluated by participants. In phase II, after 4 days in a studio with 15 bilingual actors, 30 videos were made of various experts (eg, family doctor, home care nurse, and social worker) presenting options and guidance for the decision-making process. These were integrated into an interactive website, which included a comments tool for visitors to add information. In phase III (n=21), 8 seniors (7 women, mean age 75 years), 7 caregivers, and 6 professionals evaluated the acceptability of the module and suggested improvements. Clarity of the videos scored 3.6 out of 4, length was considered right by 17 (separate videos) and 13 participants (all videos together), and 18 participants considered the module acceptable. They suggested that information should be tailored more, and that seniors may need someone to help navigate it.

Conclusions

Our interactive website with interlinked videos presenting information about options for staying independent at home was deemed acceptable and potentially helpful by a diverse group of stakeholders.

Impact of informal caregiving on older adults' physical and mental health in low-income and middle-income countries: a cross-sectional, secondary analysis based on the WHO's Study on global AGEing and adult health (SAGE)

OBJECTIVES

A high proportion of care stemming from chronic disease or disability in low-income and middle-income countries is provided by informal caregivers. The goal of this study was to determine the level of burden experienced by these caregivers, explore associated factors and assess whether caregivers' and non-caregivers' health differed.

DESIGN AND SETTING

This cross-sectional study was a secondary analysis of data on caregivers' burden, health and health risk factors in Ghana, India and the Russian Federation collected as part of the WHO's Study on global AGEing and adult health (SAGE) Wave 1.

PARTICIPANTS

Caregivers in Ghana (n=143), India (n=490) and Russia (n=270) completed the measures.

OUTCOME MEASURES

Factors associated (ie, demographics and caregiving profile variables) with burden were explored among caregivers. Then, quality of life (QOL), perceived stress, depression, self-rated health (SRH) and health risk factors were compared between caregivers and matched non-caregivers (1:2).

RESULTS

The largest caregiving subgroups were spouses and adult children. Caregivers mostly cared for one person and provided financial, social/emotional and/or physical support, but received little support themselves. Burden level ranged from 17.37 to 20.03. Variables associated with burden were mostly country-specific; however, some commonality for wealth, type of care and caregiving duration was noted. Caregivers with a moderate or high level of burden reported lower QOL and higher perceived stress than those experiencing low burden. Caregivers reported lower QOL and SRH than non-caregivers.

CONCLUSION

Given the lack of support received and consequences of the burden endured by caregivers, policy and programme initiatives are needed to ensure that caregivers in low- and middle-income countries can fulfil their role without compromising their own health.

"We don't have the infrastructure to support them at home": How health system inadequacies impact on long-term care admissions of people with dementia

OBJECTIVES

The influence of healthcare system factors on long-term care admissions has received relatively little attention. We address this by examining how inadequacies in the healthcare system impact on long-term care admissions of people with dementia. This is done in the context of the Irish healthcare system.

METHODS

Thirty-eight qualitative in-depth interviews with healthcare professionals and family carers were conducted. Interviews focused on participants' perceptions of the main factors which influence admission to long-term care. Interviews were analysed thematically.

RESULTS

The findings suggest that long-term care admissions of people with dementia may be affected by inadequacies in the healthcare system in three ways. Firstly, participants regarded the economic crisis in Ireland to have exacerbated the under-resourcing of community care services. These services were also reported to be inequitable. Consequently, the effectiveness of community care was seen to be limited. Secondly, such limits in community care appear to increase acute hospital admissions. Finally, admission of people with dementia to acute hospitals was believed to accelerate the journey towards long-term care.

CONCLUSIONS

Inadequacies in the healthcare system are reported to have a substantial impact on the threshold for long-term care admissions. The findings indicate that we cannot fully understand the factors that predict long-term care admission of people with dementia without accounting for healthcare system factors on the continuation of homecare.

Hallucinations in Healthy Older Adults: An Overview of the Literature and Perspectives for Future Research

KEY POINTS

➢ Studies suggest a substantial minority of healthy older adults have hallucinatory experiences, in line with existing evidence on hallucinations in other age groups, though it is still unclear if hallucination prevalence increases or declines with age in older cohorts.

➢ Stigma attached to both hallucinations and ageing leads to considerable under-reporting of these experiences in healthy older adults and may negatively bias how professionals, family members, and the public respond.

➢ Why and when hallucinations in healthy older adults remit, persist, or progress to other clinical disorders remains poorly understood.

➢ Current evidence points to a range of factors associated with hallucinations in older adults including decline in sensory or cognitive functioning, poor sleep, and psychosocial stressors (e.g., social isolation, loneliness, and bereavement), highlighting the need for accurate assessment and tailored interventions.

Hallucinations, though common in youth and younger adults, are not the preserve of these age groups. Accumulating evidence shows that hallucinatory experiences are also present at surprisingly high rates in healthy older adults in the general community. Furthermore, stigma and misunderstanding of hallucinations, together with ageism, may lead to under-reporting of these experiences by older adults, and misdiagnosis or mismanagement by health and mental health practitioners. Consequently, improved public and professional knowledge is needed about the nature and significance of hallucinations with advancing age. The purpose of this review is to provide a comprehensive overview, and critical analysis, of research on the prevalence, psychosocial, and neurobiological factors associated with hallucinations in people aged 60 years and over. To the best of our knowledge, this is the first review of its kind in the literature. The evidence supports a dynamic conceptualization of hallucinations, in which the emergence of hallucinations is viewed as a balance between the sensory, cognitive, or social impairments accompanying advancing age and the degree to which compensatory processes elicited by these impairments are successful. We briefly summarize the implications of the literature for aged care services and interventions, and stress that far more studies are needed in this important field of research.
