Factors determining the decision to institutionalize dementing individuals: a prospective study

Predictors of Nursing Home Placement in a Cohort of European People with Alzheimer's Disease and Other Dementia Cases Enrolled in SCU-B or Non SCU-B Centers: The RECage Study

Background

Nursing home placement (NHP) can be the final step of patients with Alzheimer's disease.

Objective

We aimed to identify NHP predictors among 508 people with dementia with a 3-year follow-up.

Methods

We analyzed data from the international observational RECage study, involving 508 people with especially Alzheimer's disease and comparing a cohort enrolled by five centers with a Special Care Unit for BPSD (behavioral and psychological symptoms of dementia) and another one enrolled by six centers lacking this facility. The tertiary objective of the study was to assess the possible role of the SCU-B in delaying NHP. We assessed the relationship of the baseline characteristics with NHP by means of univariate analysis followed by Cox's multivariate model.

Results

Patients' mean age was 78.1 years, 54.9% were women. Diagnosis mean age was 75.4 (±8.32) years; the main diagnosis was Alzheimer's disease (296; 58.4%). During follow-up, 96 (18.9%) patients died and 153 (30.1%) were institutionalized without a statistically significant difference between the two cohorts (p = 0.9626). The mean NHP time was 902 (95% CI: 870-934). The multivariable analysis without death as a competing risk retained four independent predictors of NHP: age increase (hazard ratio (HR) = 1.023, 95% CI: 1.000-1.046), patient education level increase (HR = 1.062, 95% CI: 1.024-1.101), Neuropsychiatric Inventory total increase (HR = 1.018; 95% CI: 1.011-1.026), and total Mini-Mental State Examination as a favorable factor (HR = 0.948, 95% CI: 0.925-0.971). Gender (females versus males: HR = 1.265, 95% CI: 0.899-1.781) was included in the final Cox's model for adjusting the estimates for.

Conclusions

Our data partially agree with the predictors of NHP in literature including the effect of high education level. No caregivers' factors were statistically significant.

[The impact of caregiving on the emotional well-being and health of family caregivers.]

INTRODUCTION

Family caregivers, who take care of older relatives, bear a heavy burden that can detrimentally affect their physical health and emotional well-being.

OBJECTIVE

This study aims to explore the subjective perceptions of family caregiving's impact on physical health and emotional well-being, the experience of feeling overburdened by caregiving responsibilities, and the subjective perceptions of health among caregivers of older relatives. Data from three waves of online questionnaire surveys conducted in 2018, 2020, and 2022 were analyzed.

METHOD

The COPE Index items were used to measure subjective perceptions of the impact of caregiving on physical health and emotional well-being and perceptions of being overburdened by caregiving. We present descriptive statistics and chi-square test analyses.

RESULTS

In all three waves, the majority of respondents frequently or always perceived a negative impact of caregiving on their emotional well-being and physical health, with more than half always or often experiencing caregiver overburdening. A significant correlation was observed between the perceived impact of caregiving on physical health and emotional well-being, over 70% of respondents provided similar responses to both questions. Furthermore, a significant relationship is between the prevalence of caregiver overburden and subjective perceptions of health, with those experiencing caregiver overload being more likely to report poor or very poor health. Over 60% of participants indicated frequent or constant overburden of care, with this subgroup exhibiting a higher likelihood of perceiving their health as poor or very poor.

DISCUSSION

Our results demonstrate that the caregiving burden affects both physical and emotional well-being. A significant proportion of family caregivers experience detrimental effects on their physical health and emotional well-being due to caregiving responsibilities. These negative effects were reported simultaneously by the majority of respondents.

CONCLUSION

Caregiving can have negative consequences on the health of family caregivers. Our research underscores the importance of preventive measures. Orv Hetil. 2023; 164(40): 1583-1591.

The role of Smo-Shh/Gli signaling activation in the prevention of neurological and ageing disorders

Sonic hedgehog (Shh) signaling is an essential central nervous system (CNS) pathway involved during embryonic development and later life stages. Further, it regulates cell division, cellular differentiation, and neuronal integrity. During CNS development, Smo-Shh signaling is significant in the proliferation of neuronal cells such as oligodendrocytes and glial cells. The initiation of the downstream signalling cascade through the 7-transmembrane protein Smoothened (Smo) promotes neuroprotection and restoration during neurological disorders. The dysregulation of Smo-Shh is linked to the proteolytic cleavage of GLI (glioma-associated homolog) into GLI3 (repressor), which suppresses target gene expression, leading to the disruption of cell growth processes. Smo-Shh aberrant signalling is responsible for several neurological complications contributing to physiological alterations like increased oxidative stress, neuronal excitotoxicity, neuroinflammation, and apoptosis. Moreover, activating Shh receptors in the brain promotes axonal elongation and increases neurotransmitters released from presynaptic terminals, thereby exerting neurogenesis, anti-oxidation, anti-inflammatory, and autophagy responses. Smo-Shh activators have been shown in preclinical and clinical studies to help prevent various neurodegenerative and neuropsychiatric disorders. Redox signalling has been found to play a critical role in regulating the activity of the Smo-Shh pathway and influencing downstream signalling events. In the current study ROS, a signalling molecule, was also essential in modulating the SMO-SHH gli signaling pathway in neurodegeneration. As a result of this investigation, dysregulation of the pathway contributes to the pathogenesis of various neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD).Thus, Smo-Shh signalling activators could be a potential therapeutic intervention to treat neurocomplications of brain disorders.

Factors of Dementia Caregiver Burden Differentially Contribute to Desire to Institutionalize

The experience of dementia caregiver burden is multidimensional. Little is known about how different aspects of burden contribute to the consideration of moving a loved one to a structured living facility. In the present study, caregiver burden (Zarit Burden Interview; ZBI) and consideration of structured living arrangements (Desire to Institutionalize Scale; DIS) were self-reported by 339 caregivers. Exploratory factor analysis was used to determine the ZBI factor structure; these factors were then examined via hierarchical linear regression for prediction of DIS. Factor analysis indicated a 4-factor ZBI solution: Impact on Life, Guilt, Embarrassment/Frustration, and Escape/Uncertainty. Regression analyses indicated that only Escape/Uncertainty (p < .001) was associated with DIS. Of the 4 identified factors of caregiver burden, desire to escape the caregiving role was most related to consideration of structured living arrangements. Future work should explore longitudinal contribution of this factor to determine its role in actual changes made in living arrangements.

A delicate balance: Psychotropic polypharmacy and anti-cholinergic use are correlated with fall incidence in Australian inpatients with dementia

BACKGROUND

Persons with dementia commonly experience a range of behavioural and psychological symptoms, including agitation, aggression, perceptual disturbances, and depression. While psychotropic medications are regularly prescribed to mitigate these symptoms, these agents also carry a broad adverse effect profile. This study aimed to characterize psychotropic medication use in patients with dementia, as well as identify prescribing factors associated with falls in this cohort.

METHODS

This retrospective study collected longitudinal demographic and medication data from all patients admitted to a neuro-cognitive unit at an Australian metropolitan hospital over a 2-year period. Psychotropic polypharmacy and psychotropic agent use per patient-fortnight were investigated for their association with inpatient falls.

RESULTS

All patients (n = 147) were prescribed at least one psychotropic medication, with 96% receiving anti-psychotic medications and 90% receiving benzodiazepines. Patient fall rate was significantly associated with anticholinergic drug use (Incidence rate ratio: 2.2; P < .001), as well as concomitant use of ≥5 daily psychotropic agents (Incidence rate ratio: 3.1; P = .001).

CONCLUSIONS

Patients with dementia are routinely prescribed a wide variety of psychotropic medications. Use of anticholinergic drugs and psychotropic polypharmacy are correlated with fall incidence in persons with dementia.

Factors influencing decisions to admit family members with dementia to long-term care facilities

With an aging global population and changes in family structure, there will be a need for increased formal and informal caregivers for family members with alzheimer's disease or other related dementias. Caregivers experience exhaustion, mental health issues, and competing demands; deciding to admit family members with dementia into long-term care compounds the stress. The article reports on factors that influence caregivers' decisions regarding institutionalizing their family members with dementia. Eighteen articles were included in this integrative review. Influential decision-making factors were: caregiver characteristics, care recipient characteristics, complexity of care, caregiver and family relationships, experiences with healthcare providers, financial challenges, and long-term care facility selection. Addressing these factors can provide a layer of support to caregivers and their families during the decision-making process.

Behavioural and psychological symptoms of dementia in mouse models of Alzheimer's disease-related pathology

Transgenic mouse models have been used extensively to model the cognitive impairments arising from Alzheimer's disease (AD)-related pathology. However, less is known about the relationship between AD-related pathology and the behavioural and psychological symptoms of dementia (BPSD) commonly presented by patients. This review discusses the BPSD-like behaviours recapitulated by several mouse models of AD-related pathology, including the APP/PS1, Tg2576, 3xTg-AD, 5xFAD, and APP23 models. Current evidence suggests that social withdrawal and depressive-like behaviours increase with progressive neuropathology, and increased aggression and sleep-wake disturbances are present even at early stages; however, there is no clear evidence to support increased anxiety-like behaviours, agitation (hyperactivity), or general apathy. Overall, transgenic mouse models of AD-related pathology recapitulate some of the BPSD-like behaviours associated with AD, but these behaviours vary by model. This reflects the patient population, where AD patients typically exhibit one or more BPSD, but rarely all symptoms at once. As a result, we suggest that transgenic mouse models are an important tool to investigate the pathology underlying BPSD in human AD patients.

Drivers of Long-Term Care Considerations by Persons With Cognitive Impairment

Consideration of place of care is the first step in long-term care (LTC) planning and is critical for patients diagnosed with Alzheimer's disease; yet, drivers of consideration of place of care are unknown. We apply machine learning algorithms to cross-sectional data from the CARE-IDEAS (Caregivers' Reactions and Experience: Imaging Dementia-Evidence for Amyloid Scanning) study (n = 869 dyads) to identify drivers of patient consideration of institutional, in-home paid, and family care. Although decisions about LTC are complex, important drivers included whether patients consulted with a financial planner about LTC, patient demographics, loneliness, and geographical proximity of family members. Findings about consulting with a financial planner match literature showing that perceived financial constraints limit the range of choices in LTC planning. Well-documented drivers of institutionalization, such as care partner burden, were not identified as important variables. By understanding which factors drive patients to consider each type of care, clinicians can guide patients and their families in LTC planning.

Reduced social investigation and increased injurious behavior in transgenic 5xFAD mice

Social withdrawal and agitation/aggression are common behavioral and psychological symptoms of dementia presented by Alzheimer's disease (AD) patients, with males exhibiting more aggressive behaviors than females. Some transgenic mouse models of AD also exhibit social withdrawal and aggression, but many of these models only recapitulate the early stages of the disease. By comparison, the 5xFAD mouse model of AD exhibits rapid, progressive neurodegeneration, and is suitable for modeling cognitive and behavioral deficits at early, mid-, and late-stage disease progression. Anecdotal reports suggest that transgenic 5xFAD males exhibit high levels of aggression compared to wild-type controls, but to date, indirect genetic effects in this strain have not been studied. We measured home-cage behaviors in 5xFAD males housed in three different group-housing conditions (transgenic-only, wild-type only, and mixed-genotype) and social approach behaviors when exposed to a novel free-roaming or restrained, wild-type or transgenic conspecific. Transgenic-only home cages required earlier separation due to injuries arising from aggression compared to wild-type-only or mixed-genotype cages, despite no obvious increase in the frequency of aggressive behaviors. Transgenic 5xFAD males and females also spent less time investigating free-roaming conspecifics compared to wild-type controls, but they showed normal investigation of restrained conspecifics; the genotype of the conspecific did not affect approach behavior, and there was no aggression observed in transgenic males. These findings provide evidence in an animal model that amyloid pathology ultimately leads to avoidance of novel social stimuli, and that frequent interactions between individuals exhibiting an AD phenotype further exacerbates aggressive behaviors.

Caregiver Burden and Veterinary Client Well-Being

This article describes veterinary client caregiver burden, including how it differs from other key client experiences in the palliative care setting. Caregiver burden in human relationships is reviewed. Research examining veterinary client caregiver burden in the context of serious illness (or pet caregiver burden), including the link between pet caregiver burden and client psychosocial well-being, is summarized. Risk factors for development of pet caregiver burden are discussed in the context of beginning to address how it might be reduced or prevented. Finally, suggestions are provided for veterinarians working with clients facing these issues in a palliative care setting.

Assessment of Reported Comparative Effectiveness and Safety of Atypical Antipsychotics in the Treatment of Behavioral and Psychological Symptoms of Dementia: A Network Meta-analysis

IMPORTANCE

Atypical antipsychotics offer modest effectiveness compared with placebo but with serious safety risks, including a boxed warning for the risk of death in the treatment of behavioral and psychological symptoms of dementia (BPSD). Their comparative effectiveness and safety are not fully known.

OBJECTIVE

To assess the relative benefits and safety of atypical antipsychotics in the treatment of BPSD shown in randomized clinical trials using network meta-analysis.

DATA SOURCES

PubMed/MEDLINE, Embase, PsychINFO, and Cochrane Library were searched from their inception until May 31, 2018. Key terms included dementia and atypical antipsychotics.

STUDY SELECTION

Randomized clinical trials comparing any atypical antipsychotic with another atypical antipsychotic or with placebo were included in the analysis.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers used a standardized data extraction and quality assessment form. Random-effects network meta-analyses were performed. Effect sizes were reported as standardized mean differences (SMDs) for continuous outcomes and odds ratios (ORs) for dichotomous outcomes with 95% CIs. In addition to ORs, the surface under the cumulative ranking curve (SUCRA) was ascertained, which represents the percentage of the effectiveness or safety for each treatment compared with a hypothetical treatment that would be ranked first without uncertainty.

MAIN OUTCOMES AND MEASURES

The primary effectiveness outcome assessed was the Neuropsychiatric Inventory (NPI); secondary effectiveness outcomes were the Brief Psychiatric Rating Scale (BPRS) and Cohen-Mansfield Agitation Inventory (CMAI). The primary safety outcomes were death and cerebrovascular adverse events (CVAEs). Secondary safety outcomes were extrapyramidal signs/symptoms; somnolence/sedation; falls, fracture, or injury; and urinary tract infection/incontinence.

RESULTS

Seventeen studies (5373 patients) were included. The mean (SD) age of all participants was 80.8 (3.1) years, and most were women (3748 [69.8%]). Compared with placebo, aripiprazole was associated with improvement in outcomes on the NPI (SMD, -0.17; 95% CI, -0.31 to -0.02), BPRS (SMD, -0.20; 95% CI, -0.35 to -0.05), and CMAI (SMD, -0.30; 95% CI, -0.55 to -0.05); quetiapine was associated with improvement in outcomes on the BPRS (SMD, -0.24; 95% CI, -0.46 to -0.01), and risperidone was associated with improvement in outcomes on the CMAI (SMD, -0.26; 95% CI, -0.37 to -0.15). Differences between atypical antipsychotics were not significant for effectiveness, death, or CVAE. Compared with placebo, risperidone (OR, 3.85; 95% CI, 1.55-9.55) and olanzapine (OR, 4.28; 95% CI, 1.26-14.56) were associated with increased risk of CVAEs. The SUCRA estimated relative ranking of treatments suggested that aripiprazole might be the most effective and safe atypical antipsychotic and that olanzapine provides the least benefit overall; however, these results should be interpreted with caution where point estimates (OR and SMD) show that there is no statistically significant difference.

CONCLUSIONS AND RELEVANCE

This network meta-analysis supports the existence of a trade-off between the effectiveness and safety of atypical antipsychotics in the treatment of BPSD and confirms that a single most effective and safe treatment option does not exist. Clinicians should individualize the assessment of safety risks against expected benefits when prescribing these medications to patients with dementia.

Age-related changes in social behaviours in the 5xFAD mouse model of Alzheimer's disease

In addition to memory impairments, patients with Alzheimer's disease (AD) exhibit a number of behavioural and psychological symptoms that can affect social interactions over the course of the disease. While altered social interactions have been demonstrated in a number of mouse models of AD, many models only recapitulate the initial stages of the disease, and these behavioural changes have yet to be examined over the course of disease progression. By performing a longitudinal study using the 5xFAD mouse model, we have demonstrated that transgenic females exhibit progressive alterations in social investigation compared to wild-type controls. Transgenic females exhibited an age-related reduction in interest for social odours, as well as reduced investigative behaviours towards novel conspecifics in a novel environment. However, transgenic mice exhibited no obvious olfactory deficits, nor any changes in scent-marking behaviour compared to wild-type controls, indicating that changes in investigative behaviour were due to motivation to engage with a social stimulus. This evidence suggests that transgenic 5xFAD females exhibit increased social anxiety in novel environments compared to wild-type controls. Overall, transgenic 5xFAD female mice mimic some features of social withdrawal observed in human AD patients suggesting this strain may be suitable for modelling aspects of the social dysfunction observed in human patients.

Caregiving for a Companion Animal Compared to a Family Member: Burden and Positive Experiences in Caregivers

Introduction: Research in human caregiving shows burden is often present in the caregiver and can be reduced by interventions that increase positive perceptions of caregiving. Recent work suggests burden is also present in owners of a seriously ill companion animal. To help determine if findings from the human caregiving literature are likely to generalize to companion animal caregiving, we undertook a comparison of burden and positive aspects of caregiving in these groups. Material and Methods: Caregivers recruited through social media disease support and information groups completed self-report questionnaires of burden and positive aspects of caregiving in an online research protocol. Owners of a seriously ill companion animal (n = 117) and caregivers of a family member with dementia (n = 252) were cross-sectionally compared. Analyses in the full sample were repeated in a subset (n = 75 per group) of caregivers with blindly matched demographic profiles. Results: Burden was elevated in both dementia and companion animal caregiver groups, though higher overall for dementia caregivers (p < 0.001 for full and matched samples). In contrast, greater positive aspects of caregiving were reported by companion animal caregivers (p < 0.001 for full and matched samples). In both groups, positive aspects of caregiving were negatively associated with burden (full sample p < 0.001; matched sample p < 0.05). Exploratory item analyses suggested the two groups show comparable experiences of fearing the future, guilt, and financial strain (p = ns for full and matched sample). Discussion: Although both groups showed elevated burden, companion animal caregivers reported less burden and a more positive appraisal of caregiving. Elements of burden showing similarities across groups provide a foundation for understanding caregiver burden in the companion animal owner. The inverse correlation between positive aspects of caregiving and burden suggests the impact of positive caregiving experiences should be considered in burden interventions, but because companion animal owners already positively appraise caregiving, enhancing positive aspects of caregiving may not offset burden as it does in human caregiving samples.

A problem shared is a problem halved? Comparing burdens arising for family caregivers of patients with disorders of consciousness in institutionalized versus at home care

BACKGROUND

Disorders-of-consciousness (DOC) are rare conditions leading to very severe physical and mental disabilities. Providing care for DOC patients has been described as a stressful experience, eroding the physical and psychological health of the caregiver. Different forms of care may have different impacts on the caregivers and institutionalized care has been suggested to have an unburdening effect, but this possibility has never been empirically studied. To address this issue, in this study caregiver-burden between family-caregivers who provide home care themselves and those who have placed their patients in a specialized care unit is compared.

METHOD

The demographics of the caregivers, life satisfaction, coping strategies, meaning in life, and grief reactions were assessed with questionnaires in 81 long term (m = 7.9 years) caregivers (44 patients in specialized care-units, 37 patients taken care of at home).

RESULTS

Caregiver groups were similar on the vast majority of demographic factors. Remarkably, there were no major differences in self-assessed burden and distress between the two caregiver groups. They both demonstrated generally reduced life satisfaction, were especially dissatisfied with their amount of spare time, and many caregivers in both groups demonstrated long lasting grief reactions, as well as a somewhat enhanced crisis of meaning. However, caregivers with patients in institutionalized care exhibited enhanced self-accusation as well as reduced satisfaction with their own health. Home care caregivers, on the other hand, report below average opportunities to care for themselves.

CONCLUSION

Surprisingly, placement in institutionalized care in itself does not seem to disburden caregivers as much as expected as the amount of subjective care-giving burden and reported distress is on average similarly high, although profiles differ somewhat according to type of care. Moreover, vast inter-individual variability can be observed. Further research should address the mechanisms that foster positive adjustment and reduce negative impacts for care providers regardless of type of care, enabling the health care system, institutions and self-aid groups alike, to provide more specific support for caregivers by addressing the topics of quality-of-life, own health, self care, and grief reactions.

A longitudinal study looking at and beyond care recipient health as a predictor of long term care home admission

Background

The unpaid care provided by informal caregivers allows care recipients to live longer in their homes, which often results in fewer unnecessary long term care home (LTCH) admissions. Although the relationship between care recipient’s health characteristics and institutionalization is well known, the influence of caregiver distress and caregiving coresidence and relationship on this outcome is less clear. This study examines the association of care recipient care needs, caregiver distress and caregiving coresidence and relationship with care recipient long term care home admission.

Methods

A total of 94,957 resident assessment instruments-home care (RAI-HC), completed between April 01st 2013 and April 01st, 2014 as part of a clinical practice by 14 Local Health Integration Networks (LHINs) in Ontario, Canada, were linked to LTCH admissions within 1 year after completion of the first RAI-HC assessment. Cox models were used to examine whether care recipient health care needs, caregiver distress and caregiving characteristics such as coresidence and relationship were associated with LTCH admission. Age, marital status and gender of the care recipient were included as covariates in the model.

Results

Care recipient health care needs and age were the strongest predictors of LTCH admission followed by caregiver distress and caregiving coresidence and relationship. Care recipient marital status was not significant in the survival model. Interestingly, care recipients who were cared for by a coresiding adult child caregiver were less likely to be admitted to a LTCH than care recipients cared for by a spouse caregiver coresiding or not with care recipient. Hazard rates (HR) of admission for care recipients cared for by caregivers coresiding and with other type of relationship with care recipient were not significantly different than HR of care recipients cared for by coresiding child caregivers.

Conclusions

These results emphasize the influence of caregiver distress in LTCH admission and highlight the impact of caregiving relationship and coresidence on this outcome. Policy and decision makers should consider these findings when developing and evaluating interventions aiming to avoid LTCH admissions. Moreover, caregiving coresidence and relationship should be explored in future studies with similar aims, as this information has been neglected in past research.

Factors associated with living situation among Alzheimer's caregivers in the south of Spain that affect the election of external support services

Alzheimer’s is a syndrome mainly suffered by women and the care they need is also mainly provided by other women. The aim of this paper is to describe the profile of users of professional support services and to find out if some socio-demographic factors are linked with those elections. The study was conducted from January to June 2012 thanks to the cooperation of over 41 Alzheimer’s Associations in Andalusia, in the south of Spain. A person trained by the main researcher (a social worker or a psychologist) completed the questionnaire during an interview with the caregiver. Seven hundred and seventy-eight questionnaires were analysed. Contrary to previous findings, the use of external services is not infrequent. The most commonly used services are Day Care Centres (22.4%) and Cognitive Workshops (19.2%), but Home Assistance Services are the most frequently used either alone or in combination with the other two (27.5%). A higher level of education increases the probability of choosing a nursing home. The two main factors for looking for external support are non-cohabitation and working outside the home. Among caregivers under 40 years old this is the main profile. Using no services or in low and medium intensity in service hours leads to informal caregivers being the main caregivers. The potential labour market for professional caring is reduced by a crowding-out effect. Employment reduces the chance of being a caregiver.

Caregiver Burden in Different Stages of Alzheimer's Disease

With an increasing number of patients being diagnosed with Alzheimer's disease (AD) daily, it has become one of the major problems in public health. The increase in the number of dementia patients in low- and middle-income countries is expected to be much more than that in developed countries. As a result, the economic burden of dementia, both worldwide and in Turkey, is growing. Moreover, AD leads to emotional burdens and psychological distress in family member(s) and caregiver(s) alongside the patient. Each stage of AD imposes different responsibilities on caregivers, increasing their burden. The suffering and emotional burdens of caregivers from these responsibilities lead to a decreased quality of life and disturbed body physiology. Incapacity, despair, weariness, and loneliness are the hidden emotions of this iceberg. This review aims to gather the results of studies on caregiver burden in different stages of AD, attract attention to those results that may have been ignored in Turkey, and shed light on the solutions required to overcome the problems in caregiving of AD patients.

Social Cognition, Behaviour and Relationship Continuity in Dementia of the Alzheimer Type

Social cognition can be impaired in a range of neuro-degenerative conditions, yet the impact of these difficulties on behaviour and social relationships is not yet fully understood. This study assessed social cognition in 27 participants with Dementia of the Alzheimer Type (DAT) and their co-residing partners (N = 27) and explored the relationships between social cognition, cognitive ability, relationship continuity and behaviour following diagnosis. In line with previous research, participants with dementia scored lower on social cognition tasks compared to their partners. Behaviour changes such as apathy, disinhibition and agitation in participants with dementia were significantly related to relationship continuity; however, no significant associations were found with measures of social cognition. The results of this study are discussed within a therapeutic context and in line with current guidelines and policies.

Is integrated care associated with service costs and admission rates to institutional settings? An observational study of community mental health teams for older people in England

OBJECTIVES

To evaluate the association between the degree of integration in community mental health teams (CMHTs) and: (i) the costs of service provision; (ii) rates of mental health inpatient and care home admission.

METHODS

An observational study of service use and admissions to institutional care was undertaken for a prospectively-sampled cohort of patients from eight CMHTs in England. Teams were chosen to represent 'high' or 'low' levels of integrated working practice and patients were followed-up for seven months. General linear models were used to estimate service costs and the likelihood of institutional admission.

RESULTS

Patients supported by high integration teams received services costing an estimated 44% more than comparable patients in low integration teams. However, after controlling for case mix, no significant differences were found in the likelihood of admission to mental health inpatient wards or care homes between team types.

CONCLUSIONS

Integrated mental health and social care teams appeared to facilitate greater access to community care services, but no consequent association was found with community tenure. Further research is required to identify the necessary and sufficient components of integrated community mental health care, and its effect on a wider range of outcomes using patient-reported measures. © 2016 The Authors.

Exploring Home Care Interventions for Frail Older People in Belgium: A Comparative Effectiveness Study

OBJECTIVES

To examine the effects of home care interventions for frail older people in delaying permanent institutionalization during 6 months of follow-up.

DESIGN

Longitudinal quasi-experimental research study, part of a larger study called Protocol 3.

SETTING

Community care in Belgium.

PARTICIPANTS

Frail older adults who received interventions (n = 4,607) and a comparison group of older adults who did not (n = 3,633). Organizations delivering the interventions included participants provided they were aged 65 and older, frail, and at risk of institutionalization. A comparison group was established consisting of frail older adults not receiving any interventions.

INTERVENTION

Home care interventions were identified as single component (occupational therapy (OT), psychological support, night care, day care) or multicomponent. The latter included case management (CM) in combination with OT and psychological support or physiotherapy, with rehabilitation services, or with OT alone.

MEASUREMENTS

The interRAI Home Care (HC) was completed at baseline and every 6 months. Data from a national database were used to establish a comparison group. Relative risks of institutionalization and death were calculated using Poisson regression for each type of intervention.

RESULTS

A subgroup analysis revealed that 1,999 older people had mild impairment, and 2,608 had moderate to severe impairment. Interventions providing only OT and interventions providing CM with rehabilitation services were effective in both subpopulations.

CONCLUSION

This research broadens the understanding of the effects of different types of community care interventions on the delay of institutionalization of frail older people. This information can help policy-makers to plan interventions to avoid early institutionalization.

Antipsychotic prescription amongst hospitalized patients with dementia

BACKGROUND

Antipsychotic drugs are used to treat behavioural and psychological symptoms of dementia, despite significant safety concerns regarding increased risk of stroke and mortality. The numbers of patients with dementia and related behavioural symptoms being treated in acute hospitals is increasing.

AIM

(i) to determine pre-admission and in-hospital prevalence of antipsychotic use in a national sample of patients with dementia and acute illness; (ii) identify reasons for antipsychotic use; (iii) assess features of the ward environment which impact on patients with dementia; (iv) determine availability of dementia-specific policies, training, appraisal and mentorship programs which influence service delivery.

DESIGN AND METHODS

Four-part standardized audit in 35 public acute hospitals comprising (i) retrospective healthcare record review (n = 660); (ii) prospective assessment of ward environment (n = 77); (iii) ward organization interview with clinical managers (n = 77); (iv) hospital organisation interview with senior managers (n = 35).

RESULTS

Antipsychotic drugs were prescribed to 29% of patients with dementia before hospitalization and to 41% during hospitalization; one quarter received new or additional prescriptions. Assessments for delirium (45%), dementia symptoms (39%), mood (26%), mental state (64%) and distress-provoking factors (3%) were suboptimal. Drug indications were documented in 78%. Non-pharmacological interventions were not documented. Most wards lacked environmental cues to promote orientation. Dementia-specific care pathways existed in 2 of 35 hospitals. Staff support and training programmes were suboptimal. 12% of patients were discharged with new antipsychotic prescriptions.

CONCLUSION

Antipsychotic medications are commonly prescribed for hospitalized patients with dementia in Ireland. Ward environments and dementia-related governance structures are suboptimal.

Dementia Day Care Endings: The Uncertain Limits of Care

The purpose of this study was to gain an understanding of the endings of day care for people with dementia. Staff members from a statewide random sample of dementia day care facilities were asked to think back over their practices and describe especially satisfying and dissatisfying experiences. The day care endings—either by death or by termination for other reasons—were governed by the uncertain limits of care. Dimensions of uncertainty included the capacities of the family, client, and staff, the ethical dilemmas embedded in the care; and the working relationship between staff and family. The staff experiences were shaped by Western ideologies about the "good" of community care and the "bad" of institutional care. Findings suggest the need for increased staff awareness of the uncertainty that dominates the endings of day care and for better contextualization of the endings into each client's ongoing life story.

Utilization of Respite Services: A Comparison of Users, Seekers, and Nonseekers

Four hundred fifty-eight family caregivers of Alzheimer's patients in Michigan were interviewed to identify factors associated with respite use. Of these caregivers, 176 were using respite (users), 128 had inquired about the service but had not yet used it (seekers), and 154 had neither used nor inquired about respite services (nonseekers). Separate logistic regression models were evaluated to identify users versus nonusers ( n = 458) and seekers versus nonseekers ( n = 282). Need for assistance with activities of daily living, availability of other caregivers, concern with cost, and adherence by the respite programto an established service schedule contributed significantly to the model distinguishing service users from nonusers. Caregiver burden, the presence of other caregivers, and the availability of transportation services made significant, unique contributions to the model distinguishing seekers from nonseekers.

Predictors of Time to Nursing Home Placement in White and African American Individuals With Dementia

Objective: This study examined the influence of racial group identification on nursing home placement (NHP) for individuals with dementia before and after adjusting for the possible mediating effects of the caregiving context as defined by stressprocess variables in 215 caregiver/care recipient dyads. Method: Demographics, problem behaviors, self-care impairment, and caregiver appraisal, social support, psychological well-being, and coping were used to prospectively predict Time to NHP. Results: Race was a significant predictor of NHP with African American care recipients placed significantly slower than White care recipients. Race remained a significant predictor of Time to NHP after controlling for other variables that showed independent association with Time to NHP and stress-process variables. Discussion: Findings suggest that stress-process variables are critical factors in Time to NHP; however, these variables do not explain fully the difference in Time to NHP seen in White and African American care recipients.

Providing care to relatives with mental illness: reactions and distress among primary informal caregivers

BACKGROUND

The responsibility of caring for relatives with mental illness often falls on the family members. It has been reported that the reactions to or consequences of providing care are what rendered the role of a caregiver challenging and hence a source of distress. This present study thus aimed to identify socio-demographic correlates of caregiving experiences using the Caregiver Reaction Assessment (CRA) and to examine the associations between reactions to caregiving and psychological distress.

METHODS

A total of 350 caregivers with relatives seeking outpatient care at a tertiary psychiatric hospital were recruited for this study. Distress among caregivers was assessed using the Patient Health Questionnaire (PHQ-9). The CRA was administered to measure reactions from caregiving in four domains including impact on schedule and health (ISH), impact on finance (IF), lack of family support (LFS) and caregiver esteem (CE). Participants also completed a questionnaire that asked for their socio-demographic information. Multivariable linear regression analysis was first used with domains of CRA as outcome variables and socio-demographic variables as predictors in the models. The next set of multivariable linear regression analysis tested for the association between CRA domains and distress with CRA domain scores as outcome variables and PHQ-9 score as predictor, controlling for socio-demographic variables.

RESULTS

Socio-demographic correlates of CRA domains identified were age, education, employment, income and ethnicity. Domain scores of CRA were significantly associated with PHQ-9 score even after controlling for socio-demographic variables. A higher distress score was associated with greater impact felt in the domain of ISH (β = 0.080, P < 0.001), IF (β = 0.064, P < 0.001), and LFS (β = 0.057, P < 0.001), and was associated with lower CE domain scores (β = -0.021, P < 0.05).

CONCLUSION

This study identified several socio-demographic correlates of caregiving reaction in the different domains. Each of these domains was found to be significantly associated with caregiver distress. Higher distress was associated with stronger impact on the negative domains and a lower impact in the positive domain of caregiving reaction. Interventions such as educational programs at the caregiver level, and also promoting wider social care support in these domains may help to address caregiver distress.

A systematic review of barriers and facilitators to and interventions for proxy decision-making by family carers of people with dementia

BACKGROUND

Relatives of people with dementia report that proxy decision-making is difficult and distressing. We systematically reviewed the literature about barriers and facilitators to family carers of people with dementia making proxy decisions, and interventions used to facilitate their decision-making.

METHODS

We searched electronic databases and references of included papers up to February 2014. Two authors independently evaluated study quality using a checklist.

RESULTS

We included the 30/104 papers from our search which fitted predetermined criteria and prioritized higher quality papers. Family carers report that proxy decision-making is challenging and can be distressing, especially when decisions are made against the wishes of the care recipient and support from healthcare professionals is lacking. Decision-specific manualized aids have been developed, and while results for those supporting decisions about respite and percutaneous endoscopic gastrostomy (PEG) feeding have shown promising results in pilot trials, no intervention has yet been shown to significantly reduce decisional conflict or carer burden, or increase knowledge in randomized controlled trials; a decision aid for advance care planning increased decisional conflict.

CONCLUSIONS

We recommend development and testing of decision aids targeting the decisions carers report finding most distressing, including those around where people should live, accessing services, and end of life treatments. Being provided with information to make decisions which have not previously been considered may increase feelings of conflict, suggesting these aids should be carefully targeted.

Impact of an inpatient geriatric consultative service on outcomes for cognitively impaired patients

BACKGROUND

Impact of geriatric consultative services (GCS) on hospital readmission and mortality outcomes for cognitively impaired (CI) patients is not known.

OBJECTIVE

Evaluate impact of GCS on hospital readmission and mortality among CI inpatients.

DESIGN

Secondary data analysis of a prospective trial of a computerized decision support system between July 1, 2006 and May 30, 2008.

SETTING

Study conducted at Eskenazi hospital, Indianapolis, Indiana, a 340-bed, public hospital with over 2300 yearly admissions of patients ages 65 years or older.

PATIENTS

There were 415 inpatients aged 65 years and older with CI enrolled from July 2006 to March 2008.

MEASUREMENTS

Thirty-day and 1-year mortality and hospital readmission following the index admission. Cox proportional hazard models were used to determine the association between receiving GCS, readmission, or mortality while adjusting for demographics, discharge destination, delirium, Charlson Comorbidity Index, and prior hospitalizations. The propensity score method was used to adjust for the nonrandom assignment of GCS.

RESULTS

Patients receiving GCS were older (79 years old, 8.1 standard deviation [SD] vs 76 years old, 7.8 SD; P < 0.001) with higher incidence of delirium (49% vs 29%; P < 0.001). No significant differences were found between the groups for hospital readmission (hazard ratio [HR] = 1.19; 95% confidence interval = 0.89-1.59) and mortality at 12 months of index admission (HR = 0.91; 95% confidence interval = 0.59-1.40). However, a significant increase in readmissions was observed for the GCS group (HR = 1.75; 95% confidence interval = 1.06-2.88) at 30 days postdischarge.

CONCLUSION

One-year postdischarge outcomes of CI patients who received GCS were not different from patients who did not receive the service. New models of care are needed to improve postdischarge readmission and mortality among hospitalized patients with CI.

[Fundamental study of memory impairment and non-cognitive behavioral alterations in APPswe/PS1dE9 mice]

In addition to cognitive decline, Alzheimer's disease patients also exhibit non-cognitive symptoms commonly referred to as behavioral and psychological symptoms of dementia, or BPSD. These symptoms have a serious impact on the quality of life of these patients, as well as that of their caregivers, but there are currently no effective therapies. The amyloid β-peptide (Aβ) is suspected to play a central role in the cascade leading to Alzheimer's disease, but the precise mechanisms are still incompletely known. To assess the influence of Aβ pathology on cognitive and non-cognitive behaviors, we examined locomotor activity, motor coordination, and spatial memory in male and female APPswePS1dE9 mice (Alzheimer's disease model, double transgenic mice expressing an amyloid precursor protein with Swedish mutation and a presenilin-1 with deletion of exon 9) at 5 months of age, when the mice had subtle Aβ deposits, and again at 9 months of age, when the mice had numerous Aβ deposits. Compared to wild-type mice, the male and female APPswe/PS1dE9 mice showed normal motor coordination in the rotarod test at both 5 and 9 months. In the Morris water maze test, male and female APPswe/PS1dE9 mice showed impaired spatial memory at 9 months; however, no such deficits were found at 5 months. In a locomotor activity test, male APPswe/PS1dE9 mice exhibited locomotor hyperactivity at 9 months, while females exhibited locomotor hyperactivity at both 5 and 9 months compared to the control mice. Together, these results indicate that APPswe/PS1dE9 mice developed spatial memory impairment and BPSD-like behavioral alterations resulting from Aβ accumulation.

Service utilisation and family support of people with dementia: a cohort study in England

OBJECTIVES

This study aimed to compare costs of caring for people with dementia in domiciliary and residential settings, central England.

METHODS

A cohort of people with dementia was recruited during a hospital stay 2008-2010. Data were collected by interview at baseline, and 6- and 12-month follow-up, covering living situation (own home with or without co-resident carer, care home); cognition, health status and functioning of person with dementia; carer stress; utilisation of health and social services; and informal (unpaid) caring input. Costs of formal services and informal caring (replacement cost method) were calculated. Costs of residential and domiciliary care packages were compared.

RESULTS

Data for 109 people with dementia were collected at baseline; 95 (87.2%) entered hospital from their own homes. By 12 months, 40 (36.7%) had died and 85% of the survivors were living in care homes. Over one-half of people with dementia reported social care packages at baseline; those living alone had larger packages than those living with others. Median caring time for co-resident carers was 400 min/day and 10 h/week for non co-resident carers. Residential care was more costly than domiciliary social care for most people. When the value of informal caring was included, the total cost of domiciliary care was higher than residential care, but not significantly so. Carer stress reduced significantly after the person with dementia entered a care home.

CONCLUSIONS

Caring for people with dementia at home may be more expensive, and more stressful for carers, than care in residential settings.

Together but apart: Caring for a spouse with dementia resident in a care facility

This longitudinal, exploratory study was designed to better understand the lived experience of spousal caregivers age 60 and older providing care to partners with Alzheimer's disease and related dementias resident in a care facility. Twenty eight spousal caregivers were interviewed up to three times over a period of 2 years, and long-term care facility staff from four locations across British Columbia (BC), Canada participated in four focus groups. Thematic analysis of interview and focus group transcripts revealed a central, unifying theme 'together but apart'. The results identify key targets for policy makers and service providers to support positive health and well-being outcomes for spousal caregivers providing care to their partners diagnosed with Alzheimer's disease and related dementia and living in care facilities.

[Psychoneuroimmunological predictors for burden in older caregivers of patients with Alzheimer's disease]

INTRODUCTION

The responsibility of giving care to patients with Alzheimer's disease (AD) may result in health changes in the older caregiver. It is important to explore the factors which influence the presence of care burden and to create strategies to face this condition. In this context, the aims of present study were to investigate the relationships between psychoneuroimmunological parameters and determine the predictors to burden in older caregivers of patients with AD.

MATERIAL AND METHODS

A total of 30 AD older caregivers participating in the «Cognitive and Functional Kinesiotherapy Program in Elderly with Alzheimer's disease«(PRO-CDA)», de Rio Claro, SP-Brazil, were submitted to an assessment protocol to evaluate the psychoneuroimmunological parameters. A descriptive statistical analysis, Pearson correlation and multiple linear regressions were performed.

RESULTS

The mean age of caregivers was 71.3 (±9.3), and predominantly are first-grade relatives. The caregiver burden was associated with depressive symptoms (r=0.60, P<.001), caregiver distress (r=0.68, P<.001), and neuropsychiatric disorders of AD patients (r=0.53, P<.001). The multiple regression analysis confirmed depressive symptoms and neuropsychiatric disturbances as predictors of caregiver burden.

CONCLUSION

Caregiver burden is associated with, and influenced by parameters related to the caregiver psychological suffering and to characteristics inherent to AD. Thus, it is important to find strategies and implement non-pharmacological programs to provide support to older caregivers, and to assist in the treatment of patients with AD, in order to improve the integral health of this population.

Topical issues in old age psychiatry

With advancements in medical science over past decades, our aging population has increased substantially. Census studies in 2001 showed that 429,100 of the population of the Republic of Ireland were aged 65yrs and older, making up 11.2% of the overall population. While the overall population of the Republic is expected to remain stable over the next ten years, the demographic projections for the elderly population is for significant growth: numbers of over 65yrs are expected to increase by nearly 108,000 people between 1996 - 2011, comprising over 14.1% of the overall population. In particular, our communities will contain a much higher proportion of octogenarians and nonagenarians: at present 21% of our over 65's are 80 yrs or older; by 2011, it is projected that this number will increase to 25%. In tandem, the prevalence of dementia will increase.

In 2000, it was estimated that 31,000 people suffered with dementia in the Republic of Ireland, and this figure is expected to increase by 5000 cases per year between 2001-2011. The ultimate outcome of this demographic shift, will be higher demands on medical services for older people, especially geriatric medicine and old age psychiatry. This paper will focus on two particular aspects of management which will increasingly impact on the work of old age psychiatrists – medicolegal issues and management issues in dementia.

Minimizing confusion and disorientation: cognitive support work in informal dementia caregiving

Drawing from ethnographic fieldwork and in-depth interviews, I explain how informal dementia caregivers attempt to reduce the affected individual's moments of confusion and disorientation through cognitive support work. I identify three stages through which such support takes shape and then gradually declines in usage. In a first stage, family members collaborate with affected individuals to first identify and then to avoid "triggers" that elicit sudden bouts of confusion. In a second stage, caregivers lose the effective collaboration of the affected individual and begin unilateral attempts to minimize confused states through pre-emptive conversational techniques, third-party interactional support, and social-environment shifts. In a third stage, caregivers learn that the affected individual has reached a level of impairment that does not respond well to efforts at reduction and begin abandoning strategies. I identify the motivations driving cognitive support work and discuss the role of lay health knowledge in dementia caregiving. I conclude by considering the utility of cognitive support work as a concept within dementia caregiving.

Increased health service utilization costs in the year prior to institutionalization: findings from the canadian study of health and aging

OBJECTIVES

The objective of this study was to characterize patterns of formal health service utilization costs during older adults' transition from community to institutional care.

METHODS

Participants were 127 adults (age ≥ 65) from the British Columbia sample (N = 2,057) of the Canadian Study of Health and Aging who transitioned from community to institutional care between 1991 and 2001. Health service utilization costs were measured using Cost-Per-Day-At-Risk at five time points: > 12 months, 6-12 months, and ≤ 6 months preinstitutionalization, and ≤ 6 months and 6-12 months postinstitutionalization. Cost-Per-Day-At-Risk was measured for Continuing Care, Medical Services Plan, and PharmaCare costs by calculating total health service use over time, divided by the number of days the participant was alive.

RESULTS

Significant differences in Cost-Per-Day-At-Risk were observed for Continuing Care, Medical Services Plan, and PharmaCare costs over time. All health service utilization costs increased significantly during the 6-12 months and ≤ 6 months prior to institutionalization. Postinstitutionalization Continuing Care costs continued to increase at ≤ 6 months before decreasing at 6-12 months, while decreases occurred for Medical Services Plan and PharmaCare costs relative to preinstitutionalization costs.

CONCLUSIONS

The increases in costs observed during the year prior to institutionalization, characterized by a flurry of health service utilization, provide evidence of distinct cost patterns over the transition period.

Transitions to long-term care: how do families living with dementia experience mealtimes after relocating?

Food and mealtimes play a central role in our lives and often hold great meaning. This study is a secondary analysis of a subset of data collected from a 6-year longitudinal qualitative study called Eating Together (ET), which sought to better understand the experiences around food and mealtimes for community dwelling persons with dementia (PWD) and their primary care partners (CP). Several PWD and, in some cases, their spousal CP, relocated to long-term care (LTC) during the conduct of the ET study. To understand how this relocation influenced the meaning of meals, a subset of those who experienced this transition were selected and analysis specific to this issue was undertaken. Seven families were included in this thematic inductive analysis. Findings revealed five themes related to the different mealtime experience in the LTC home, including systemizing the meal, adjusting to dining with others, holding on to home, evolving mealtime roles, and becoming "at home." Understanding how families adapt to commensal dining in LTC may be relevant to successful relocation. This work furthers this understanding and provides a basis for person-centered mealtime practices that promote adaptation.

An overview of the LASER-AD study: a longitudinal epidemiological study of people with Alzheimer's disease

Research into the epidemiological, clinical characteristics and economic impact of dementia is critical to increase understanding and better inform care and policy, and empower people with Alzheimer's disease (AD) and their families to make preparations and timely decisions about accommodation, care and treatment. The LASER-AD longitudinal study of people with AD and their carers has contributed to our understanding of the progression, characteristics and costs of the disease, and to developing tools that help detect dementia earlier, and screen and identify problems experienced by carers. Our work on quality of life shows that even those with severe dementia can report this meaningfully, although family proxy ratings of quality of life do not necessarily mirror the views of the individual. Despite the impact of the disease process, people with AD experience well-being in adversity and still live fulfilling lives. The study highlights the high prevalence and severity of neuropsychiatric symptoms, carer anxiety, depression and abusive behaviour. It informs future directions for possible interventions, in particular the central role of carer coping strategies in predicting carer mental illness. Current research is building on our findings, which have also been used to inform national and international plans for managing people with dementia and their carers.

Distress of the Caregiver in Acquired Brain Injury: Positive aspects of care to moderate the effects of psychological problems

Acquired brain injury (ABI) causes numerous problems, including cognitive and personality changes, which can be quite stressful for caregivers. In this study, we aimed to adapt an instrument to measure caregivers’ distress, the Relative Version of the Head Injury Behaviour Scale (HIBS; Godfrey et al., 2003) to the Spanish language and to determine whether the positive aspects of caregiving moderate the effects of the psychological problems of ABI on caregivers’ distress. Moderation analyses indicated that positive aspects of caregiving involving one's outlook on life reduced the association between psychological problems and caregivers’ distress. The findings suggest that although the caregiver role is a source of distress, this role can also become a source of satisfaction, actually contributing to reducing caregivers’ distress. The importance of promoting the positive aspects of caregiving in rehabilitation programmes is discussed.

No association of COMT val158met polymorphism and psychotic symptoms in Lewy body dementias

We sought to determine whether the COMT val158met polymorphism (rs4680) is associated with delusions and hallucinations in people with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). A total of 218 individuals, recruited from centres in Norway, Sweden and the UK were included in this study; 121 with clinically or neuropathologically diagnosed DLB/PDD and 97 age-matched, cognitively normal controls. All participants with dementia underwent serial evaluation of neuropsychiatric symptoms to assess the presence of persistent delusions and hallucinations using the Columbia University Scale for Psychopathology in Alzheimer's disease, the Neuropsychiatric Inventory or the Present Behavioural Examination. Severity of cognitive impairment was measured using the Mini Mental State Examination (MMSE). Both controls and participants with dementia were genotyped for rs4680. In contrast to previous findings, analysis by logistic regression failed to find any associations between rs4680 and psychotic symptoms. Larger studies in well characterised cohorts are warranted in order to investigate this relationship further.

Using mental imagery to improve memory in patients with Alzheimer disease: trouble generating or remembering the mind's eye?

This study was conducted to understand whether patients with mild Alzheimer disease (AD) could use general or self-referential mental imagery to improve their recognition of visually presented words. Experiment 1 showed that, unlike healthy controls, patients generally did not benefit from either type of imagery. To help determine whether the patients' inability to benefit from mental imagery at encoding was due to poor memory or due to an impairment in mental imagery, participants performed 4 imagery tasks with varying imagery and cognitive demands. Experiment 2 showed that patients successfully performed basic visual imagery, but degraded semantic memory, coupled with visuospatial and executive functioning deficits, impaired their ability to perform more complex types of imagery. Given that patients with AD can perform basic mental imagery, our results suggest that episodic memory deficits likely prevent AD patients from storing or retrieving general mental images generated during encoding. Overall, the results of both experiments suggest that neurocognitive deficits do not allow patients with AD to perform complex mental imagery, which may be most beneficial to improving memory. However, our data also suggest that intact basic mental imagery and rehearsal could possibly be helpful if used in a rehabilitation multisession intervention approach.

Caregiver burden, health utilities, and institutional service use in Alzheimer's disease

OBJECTIVE

This study examined the moderating effect of caregiver burden on the relationship between the health status of Alzheimer's disease (AD) patients and their use of institutional services (i.e., hospitalization, nursing home, and residential care).

METHODS

Data were obtained at baseline and at 3, 6, and 9 months following study entry on 421 community-dwelling patients with AD in the Clinical Antipsychotic Trials of Intervention Effectiveness for AD. The outcome variable includes use of any institutional services. Logistic regression was employed to estimate the interaction between Health Utility Index Mark III score (a general health status measure) and four concurrent caregiver burden measures at outcome. Marginal effects were calculated and plotted using random effects models for observations at multiple time points per individual. Average effects were calculated across all observations using models without random effects.

RESULTS

Random effects results suggest that caregiver burden weakens the inverse relationship between health utilities and institutional service use, leading to greater likelihood of institutional use than would be expected at a given level of health. This is indicated by positive and significant signs on the Health Utility Index Mark III*caregiver burden interaction when burden is measured using the Caregiver Distress Scale, Beck Depression Inventory, and Caregiver Assessment Survey (all p < 0.05). It is reinforced by positive and significant average effects deriving from Caregiver Distress and Beck Depression Inventory models without random effects (both p < 0.10). Results derived from the Burden Interview Scale, although positive, were non-significant and weak by comparison.

CONCLUSION

Caregiver support interventions should be offered to individuals caring for less-advanced AD patients. Otherwise, healthy patients may be at increased risk for institutionalization when caregivers experience high levels of burden.

Depressive symptoms and level of physical activity in patients with Alzheimer's disease

AIM

The purpose of this study was to determine the presence of depressive symptoms in patients with Alzheimer's disease, to assess whether there was an association between physical activity level and depressive symptoms in this population, and to assess whether more active patients had lower rates of depressive symptoms when compared with less active patients.

METHODS

The study included 37 patients with Alzheimer's disease and used the following instruments: the Geriatric Depression Scale, the Cornell Scale for Depression in Dementia and the Baecke Questionnaire Modified for the Elderly. The Shapiro-Wilk test was used to determine whether the data were normally distributed. The Spearman correlation test and the Mann-Whitney U-test was used. P-values less than 5% were considered statistically significant.

RESULTS AND DISCUSSION

The prevalence of depressive symptoms in the sample was 35.13%. The Spearman correlation test verified the relationship between level of physical activity and depressive symptoms (rho = -0,4), and between the sports activities domain and depressive symptoms (rho = -0,4). Patients who were more active had lower depressive symptoms.

CONCLUSIONS

The prevalence of depressive symptoms in the sample was 35.13%. Patients who were more active had lower rates of depressive symptoms.

Family caregivers' decision process to institutionalize persons with Parkinson's disease: a grounded theory study

BACKGROUND

Parkinson's disease is a degenerative neurological disorder affecting millions. Treatment priorities focus on delaying its progression and resulting disability, and helping individuals continue to live at home as long as possible. This often requires long-term assistance by family caregivers.

AIMS

The purpose of the study was to understand (1) family caregivers' experiences in caring for a relative with Parkinson's disease, and (2) factors that influenced the decision to place the relative in a long-term care facility.

PARTICIPANTS

Twenty semi-structured interviews were conducted with adult family members (17 female, 3 male) acting as full-time primary caregivers for a relative with Parkinson's disease.

METHOD

Grounded theory was used to explore the process of healthcare decision-making and to illustrate the experiences of caring for persons with Parkinson's disease. The interview questions centered on family caregiving experiences and on how these caregivers made long-term care decisions on behalf of their loved ones. Data were coded and analyzed using dimensional analysis.

FINDINGS

The caregiving model developed from the data illustrated that heightened caregiver strain-a risk factor for institutionalization-results from increased caregiving load and increased illness severity over time. Safety concerns, falls with severe injury, managing changes in health, and depleted support also influenced the decision to institutionalize the relative with Parkinson's disease.

CONCLUSIONS

Implications from this research suggest the need for enhanced communication between providers and caregivers, formalized caregiver assessments, improved care coordination and family-centered interventions to avoid premature institutionalization.

[Factors associated with dementia caregivers' preference for institutional care]

INTRODUCTION

The prevalence of dementia is growing in Spain, and so is the number of caregivers who are considering the institutionalization of their relatives. The purpose of this study is to identify which variables are associated with caregivers' desire for institutionalization their dementia relatives.

PATIENTS AND METHODS

Informal caregivers of 243 individuals suffering from dementia were interviewed. Predisposing variables (sociodemographic and contextual variables), stressors (dementia-related and caregiving-related aspects), appraisals (of circumstances and caregivers' role), resources (personal and community-based resources) and the desire to institutionalize were evaluated.

RESULTS

Over half of the caregivers (52.6%) indicated that they had some desire to institutionalize their relatives with dementia. Stepwise regression analysis revealed that caregivers' consideration to institutionalize was associated with being a male caregiver, not being the spouse of the dementia patient, and with a higher consideration and higher use of community-based formal resources (short-term nursing home use, adult day care centres and psycho-stimulation).

CONCLUSIONS

Assessing and using formal resources outside their homes help caregivers overcome barriers that keep them from considering the institutionalization of their relatives. The difficulty in considering institutionalizing their relatives is more evident among spouses, who have stronger attachments with the dementia patients, especially among females, who probably feel obliged to continue developing caregiver roles because of their gender.
