The relationship between self-destructive behaviour and nursing home environment

Prevalence of Suicidal Behaviors in Residents of Long-Term Care Facilities: A Systematic Review and Meta-Analysis

BACKGROUND

Long-term care facilities (LTC) plays a pivotal role in caring for geriatric population. However, the risk of suicide in long-term care institutions among older individuals is little understood (e.g., nursing homes, assisted living facilities).

OBJECTIVE

The purpose of this systematic review is to pool and meta-analyze the data on prevalence of suicidal behaviors in geriatric population residing in long-term care facilities.

METHODS

We have conducted the systematic review in accordance with the PRISMA guidelines. The utilized databases are Pubmed, Medline, Google scholar and Scopus. The Meta-analysis was done using OpenMeta [analyst] software. Subgroup analysis was also performed.

RESULTS

After running an analysis on pooled data from twenty cross-sectional studies with 3,023,224 participants, the prevalence of suicidal behavior is 6.4% (95% CI = 5.7-7) in LTC.

CONCLUSION

This meta-analysis shows pooled prevalence of suicidal behavior among geriatric residents of LTC was found to be moderately high all over the world.

Resistance to Eating in People with Dementia Living in Long-term Care Facilities: Gaps between Common and Good Practices

OBJECTIVES

The present study aims to explore the perception of common and best practices for dealing with resistance to eating of persons with dementia living in long-term care facilities.

METHODS

Forty-two staff members working in long-term care facilities were interviewed. They worked in four Spanish long-term care facilities; 21 were nursing assistants and 21 technical staff. Participants heard a vignette in which person with dementia showed resistance to eating. Participants were asked how a situation like that is commonly managed by their workmates, and how the situation should be managed. Responses were content-analyzed.

RESULTS

Strategies mentioned by participants were quite diverse and did not converge on common ground that harmonizes their responses. Less than half of the participants considered person-centered strategies as a best practice. Those strategies were lower on assistant carers, compared to technical staff.

CONCLUSIONS

Resistance to eating is a common situation faced by professionals. Nonetheless, there is not a common procedure to deal with this situation. Resistance to eating was seen more as a problem to be eradicated than a behavior to be understood.

CLINICAL IMPLICATIONS

Staff development initiatives are necessary in relation to mealtime situations. They should consider work position and competencies needed by assistant carers.

Effect of the Physical Environment on Health and Well-Being of Nursing Homes Residents: A Scoping Review

OBJECTIVES

In what way the physical environment of nursing homes (NHs) influences the health and well-being of nursing residents is not well codified. The authors aimed to review scientifically based knowledge on this topic.

DESIGN

A systematic scoping review of research into the effect that physical environment in nursing homes has on residents' health.

SETTING AND PARTICIPANTS

Search for relevant English-language articles in PubMed and the Cochrane database before April 15, 2022. Article selection and data extraction were performed by 2 researchers. Studies were included if conducted on nursing home residents and if they examined associations between components of the physical environment and health outcomes.

MEASURES

The review was performed in accordance with the PRISMA statement.

RESULTS

Of 1347 articles retrieved, 59 met the inclusion criteria-40 observational, 1 survey, and 18 interventional studies, of which 5 were randomized controlled trials. Certain environmental features repeatedly show significant positive effect on resident's health, such as noise reduction, tuning of lighting, natural light, easy access to garden, dining environment, and resident-centered interior renovation. Nursing home size was not found to have a direct relationship to resident health and well-being, although it is related to more than only the physical environment (eg, social environment).

CONCLUSIONS AND IMPLICATIONS

This review provides guidance in selective areas of the physical environment for the design of nursing homes, with potential benefits for the health and well-being of residents.

Resident-to-Resident Elder Mistreatment in Residential Aged Care Services: A Systematic Review of Event Frequency, Type, Resident Characteristics, and History

OBJECTIVES

Resident-to-resident elder mistreatment (R-REM) between residents living in residential aged care (RAC) services is a challenging issue in relation to the care of older people. Evidence suggests that R-REM, such as verbal, physical, and sexual conflict between residents, is a common and pervasive issue. This review examines the frequency with which R-REM occurs in RAC services; identifies the types of R-REM that occur; and provides an overview of the reported characteristics of both the victim and perpetrator involved in the R-REM event.

DESIGN

A systematic review was conducted. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, Ageline, and Cochrane Library to identify qualitative and quantitative studies published in the English language.

SETTING AND PARTICIPANTS

Residents living in RAC services.

MEASURES

Data on frequency and characteristics were collated, and aggregate proportions were calculated where possible.

RESULTS

Twenty-six studies were identified; most (n = 20) were published in the United States. The overall proportion of residents engaged in R-REM was provided by 7 quantitative studies with the estimated frequency reported to be 12% to 23%. For qualitative studies, the number of care staff reporting to have observed R-REM ranged from 18.7% to 98.0%. Physical and verbal abuse were the most commonly reported types of mistreatment. Characteristics of the perpetrator of R-REM were reported in 12 (46.2%) studies. Overall, the mean age of perpetrators was 80.93 years, most were men (83.2%), and 64.4% had dementia and/or Alzheimer diagnosis. Characteristics of the victim and the history of R-REM were largely omitted from the published studies.

CONCLUSION AND IMPLICATIONS

The findings from the review broaden understanding on the extent of R-REM; the individual and event characteristics and ultimately support care planning, policy, and direction for future research. To improve understanding, quality of care, and RAC residents' well-being, further studies are recommended to address the identified gaps in knowledge.

The Homestead: Developing a Conceptual Framework through Co-Creation for Innovating Long-Term Dementia Care Environments

Alternative care environments for regular nursing homes are highly warranted to promote health and well-being of residents with dementia that are part of an age-friendly and dementia-friendly city and society. Insight is lacking on how to translate evidence-based knowledge from theory into a congruent conceptual model for innovation in current practice. This study reports on the co-creation of an alternative nursing home model in the Netherlands. A participatory research approach was used to co-create a conceptual framework with researchers, practitioners and older people following an iterative process. Results indicate that achieving positive outcomes for people with dementia, (in)formal caregivers, and the community is dependent on how well the physical, social and organizational environment are congruently designed. The theoretical underpinnings of the conceptual model have been translated into "the homestead," which is conceptualized around three main pillars: activation, freedom and relationships. The Homestead Care Model is an illustrative example of how residential care facilities can support the development of age-friendly communities that take into consideration the needs and requirements of older citizens. However, challenges remain to implement radical changes within residential care. More research is needed into the actual implementation of the Homestead Care Model.

The securitisation of dementia: socialities of securitisation on secure dementia care units

Nearly 50 million people around the world live with dementia, with statistics predicting a steady increase in prevalence for the foreseeable future. There is a need for comprehensive and compassionate dementia care. Long-term care homes have built special care units for people living with middle- to late-stage dementia. Among other services, these care units often use innovative security technologies that monitor and curtail movement beyond unit exit doors. As care-givers and technology developers grapple with the ethical dilemma of autonomy and risk management, researchers are beginning to investigate the social impact of these security technologies. The present research contributes to this line of inquiry. Fieldwork was carried out on two secure long-term care units for people living with dementia. Ethnographic accounts will illustrate how security technology creates socialities of securitisation on a secure dementia unit. Using securitisation theory, I will argue that dementia has been redefined, shifting it from a health issue to a security issue. The discursive construction of dementia as a security issue will be considered in terms of the co-constructed notions of vulnerability, risk, security threat and security challenge with respect to people living with dementia. The paper investigates how securitisation influences the ethics of dementia care.

Study of scientific publications (2002-2017) on suicidal ideation, suicide attempts and self-neglect of elderly people hospitalized in Long-Term Care Establishments

This is a study on scientific work on the ideation, suicide attempt and self-neglect of elderly residents in LTCEs from 2002 to 2017. Documents were retrieved from the following sources: BVS/SP, SciELO, Scopus, PubMed and Web of Science, with the following descriptors: suicide attempt, suicidal ideation, self-neglect, elderly, long-term care establishment, and their correspondents in Portuguese, Spanish and French. Twenty-six papers on the subject were found. There is a consensus among the authors, whose texts are analyzed here, concerning the factors that lead the elderly to suicidal behavior: depression, illness and pain, complicated and traumatic mourning, anxiety and despair after recovery from depressive episode, poor living conditions, death of close relatives, friends, family conflicts, family history of self-inflicted events. The protection factors found are religiosity, optimistic lifestyle, satisfaction with life and investment in the autonomy and power of relationships and communication and monitored drug therapy for mental disorders such as depression.

Risk Factors for Depression in Long-Term Care: A Systematic Review

OBJECTIVES

Depression rates are substantially higher among older adults in long-term care when compared with older adults in the community. Furthermore, the needs of older adults in long-term care are increasingly complex, and risk factors that contribute to depression in this population are unclear. This limits not only the identification of those at risk for depression but also the development of therapeutic interventions. This review summarizes the evidence on risk factors for depression.

METHODS

Searches were performed using CINAHL, Cochrane Library, Ovid Medline, PsycINFO and Scopus for research published 1980-2017. Data were reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

RESULTS

Eleven studies met the inclusion criteria, representing a total of 11,703 participants, with a mean sample size of 1,064. The most consistently supported risk factor was cognitive impairment, followed by functional impairment and baseline depression score.

CONCLUSIONS

The studies lacked a systematic approach to investigating risk factors for depression, and the research remains largely atheoretical. Few risk factors were consistently studied, with over 20 risk factors examined no more than once each. Psychological and environmental risk factors, which may be modifiable and have the potential to inform therapeutic interventions and preventative strategies, remain under-studied.

CLINICAL IMPLICATIONS

The most consistently supported risk factors-cognitive impairment, functional disability and baseline depression score-have the potential to inform screening protocols and should be monitored longitudinally. When developing psychotherapeutic interventions, close consideration should be given to cognitive and functional impairment as barriers to implementation and uptake.

What makes a nursing home homely? A Scottish based study, using Q methodology of the perceptions of staff, residents and significant others

Background

A 'homely' nursing or care home is of international interest and comes from a wide variety of academic disciplines and from policy makers and charities. However, 'homeliness' is a dynamic and complex concept and one worthy of further investigation.

Aims

(a) To explore what is meant by 'homely' in the care home environment, (b) to explore whether a 'homely' care home is a priority in the expressed views of residents, staff and visitors, and (c) to explore features contributing to the creation of homeliness in the care home environment.

Method

A mixed methodology was used - a narrative literature review, an environmental assessment using the Sheffield care environment assessment matrix (SCEAM) tool and Q methodology. Participants (n = 16) included staff, residents and their relatives from care homes in the west of Scotland.

Results

The literature review generated eight themes: home as space; home as place, design features, homeliness, the outdoors, home and identity, dementia design and specific rooms. The SCEAM revealed that homely environments supported personalisation, safety and health, privacy, community, comfort and awareness, choice and staff accommodation. The Q method revealed three factors: standards driven, making the most of it and a sense of belonging.

Conclusion

The results showed that staff and relatives placed priority on features included in national standards of care, while residents placed more importance on a feeling of belonging.

Building design for people with dementia: a case study of a UK care home

Purpose

This paper aims to investigate the impact that building design has upon the quality of life for residents of a care home who have dementia. To present a balanced perspective, carers within the care home also participate in the research.

Design/methodology/approach

A case study methodological approach was adopted using one care home, ten residents and five staff as a sample frame. During interviews conducted, participants were asked semi-structured questions on how building design features impact upon the quality of life of residents. Questions posed focussed upon key design principles that emerged from a detailed review of extant literature.

Findings

Building design for people with dementia must consider a complex array of features to provide a safe and habitable living space for residents and family members who visit. This living space must also be suitably utilitarian and provide a workable environment for staff. Hence, an appropriate balance between these two competing requirements must be attained, and often a tailor-made solution is required that fits the individual’s level of dementia. Three prominent areas that study participants expressed a desire for were a safe environment; support for wayfinding, orientation and navigation; and access to nature and the outdoors.

Originality/value

The work reports upon the rarely discussed issue of building design for people with dementia and could be used by policymakers and construction firms to enhance their knowledge capabilities in this area. The research concludes with direction for future research which should seek to provide more evidence-based research vis-a-vis perception enquiry and extend this seminal work to a larger sample of care homes or people with dementia living at home.

Dementia-friendly wards

Purpose

The purpose of this paper, practice-based mixed methods small-scale study, is to explore the design features of a “dementia friendly” acute ward environment and, staff views on the implications of daily activity engagement for patients with dementia.

Design/methodology/approach

Eight staff members of the multidisciplinary team who work full time on an acute “dementia friendly” ward completed semi-structured questionnaires. Thematic analysis explored responses to the open-ended questions, and a further environmental assessment tool rated features of the “dementia friendly” ward design, on promoting aspects of well-being in patients with dementia.

Findings

Six overarching themes were found. These included: contrasting ward colours; clear ward signage; positive staff interaction; memorabilia, and activity rooms and items, had a positive influence on patient interaction, well-being and engagement in daily activities. The audit scores were rated highly for various aspects of the ward design. These included: the ward design promoting patient interaction, well-being, mobility, orientation, continence, eating and drinking and calm and security.

Research limitations/implications

This practice-based small-scale study highlights the importance that a “dementia friendly” ward environment may have on patient engagement and well-being, from a daily activity perspective. Further research into the key aspects of design that enable meaningful daily activity engagement is required.

Practical implications

This study supports staff perceived views of the positive influence that “dementia friendly” design may have for patients with dementia. Both the physical design modifications of the ward and staff interaction were highlighted as positively influencing patient well-being, and daily activity engagement. Staff members also felt that they needed to balance the clinical ward priorities, with the contextual requirements of patients with dementia, to establish an effective “dementia friendly” ward.

Originality/value

The value of this research is the combined consideration of an environmental assessment tool and qualitative interviews with members of the multidisciplinary team.

Suicide attempts and completions in Veterans Affairs nursing home care units and long-term care facilities: a review of root-cause analysis reports

OBJECTIVE

Suicide was the 10th leading cause of death for Americans in 2010. The suicide rate is highest among men who are aged 75 and older. The prevalence of suicidal behavior in nursing homes and long-term care (LTC) facilities was estimated to be 1%. This study describes the systemic vulnerabilities found after suicidal behavior in LTC facilities as well as steps to decrease or mitigate the risk.

METHOD

This is a retrospective review of root-cause analysis (RCA) reports of suicide attempts and completions between 1 January 2000 and 31 December 2013 in the Veterans Health Administration LTC and nursing home care units. The RCA reports of suicide attempts and completions were coded for patient demographics, method of attempt or completion, root causes, and actions developed to address the root cause.

RESULTS

Thirty-five RCA reports were identified. The average age was 65 years, 11 had a previous suicide attempt, and the primary mental health diagnoses were depression, posttraumatic stress disorder, and schizophrenia. The primary methods of self-harm were cutting with a sharp object, overdose, and strangulation.

CONCLUSIONS

It is recommended that all staff members are aware of the signs and risk factors for depression and suicide in this population and should systematically assess and treat mental disorders. In addition, LTC facilities should have a standard protocol for evaluating the environment for suicide hazards and use interdisciplinary teams to promote good communication about risk factors identified among patients. Finally, staff should go beyond staff education and policy to make clinical changes at the bedside. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

Suicidal behavior and assisted suicide in dementia

BACKGROUND

Concerns about suicide risk in people with dementia have been increasing in recent years along with a discourse about rational suicide and assisted suicide.

METHODS

A systematic narrative literature review of suicidal behavior and assisted suicide in persons with dementia.

RESULTS

Most studies that have examined the spectrum of suicidal ideation, attempted suicide and suicide in dementia have methodological limitations but the overall suicide risk does not appear to be increased. When suicidal behavior does occur, common themes include the presence of psychiatric comorbidity, mainly depression; occurrence early in the dementia course with preserved insight and capacity; and an increased risk in younger people. The emerging discourse on rational and assisted suicide has been spurred by early and pre-symptomatic diagnosis and poses a number of ethical challenges for clinicians including the role of proxy decision-makers.

CONCLUSIONS

Although dementia might not confer a significant overall risk for suicidal behavior, clinicians still need to consider the potential for suicide in vulnerable individuals particularly early in the dementia course.

Suicide risk in long-term care facilities: a systematic review

OBJECTIVE

Suicide risk is highest in later life; however, little is known about the risk of suicide among older adults in long-term care facilities (e.g., nursing homes and assisted living facilities). The goal of this paper is to review and synthesize the descriptive and analytic epidemiology of suicide in long-term care settings over the past 25 years.

METHODS

Four databases (PubMed, CINAHL Plus, Web of Knowledge, and EBSCOHost Academic Search Complete) were searched for empirical studies of suicide risk in nursing homes, assisted living, and other residential facilities from 1985 to 2013. Of the 4073 unique research articles identified, 37 were selected for inclusion in this review.

RESULTS

Of the included reports, 21 were cross-sectional, 8 cohort, 3 qualitative, and 5 intervention studies. Most studies indicate that suicidal thoughts (active and passive) are common among residents (prevalence in the past month: 5-33%), although completed suicide is rare. Correlates of suicidal thoughts among long-term care residents include depression, social isolation, loneliness, and functional decline. Most studies examined only individual-level correlates of suicide, although there is suggestive evidence that organizational characteristics (e.g., bed size and staffing) may also be relevant.

CONCLUSIONS

Existing research on suicide risk in long-term care facilities is limited but suggests that this is an important issue for clinicians and medical directors to be aware of and address. Research is needed on suicide risk in assisted living and other non-nursing home residential settings, as well as the potential role of organizational characteristics on emotional well-being for residents.

The relationship between the quality of the built environment and the quality of life of people with dementia in residential care

While there is considerable evidence on the impact of specific design features on problems associated with dementia, the link between the quality of the built environment and quality of life of people with dementia is largely unexplored. This study explored the environmental and personal characteristics that are associated with quality of life in people with dementia living in residential aged care. Data were obtained from 275 residents of 35 aged care homes and analysed using linear regression. The quality of the built environment was significantly associated with the quality of life of the resident measured by global self-report. Environmental ratings were not associated with proxy or detailed self-report ratings. Higher quality of life is associated with buildings that facilitate engagement with a variety of activities both inside and outside, are familiar, provide a variety of private and community spaces and the amenities and opportunities to take part in domestic activities.

Functional analysis-based interventions for challenging behaviour in dementia

BACKGROUND

Functional analysis (FA) for the management of challenging behaviour is a promising behavioural intervention that involves exploring the meaning or purpose of an individual's behaviour. It extends the 'ABC' approach of behavioural analysis, to overcome the restriction of having to derive a single explanatory hypothesis for the person's behaviour. It is seen as a first line alternative to traditional pharmacological management for agitation and aggression. FA typically requires the therapist to develop and evaluate hypotheses-driven strategies that aid family and staff caregivers to reduce or resolve a person's distress and its associated behavioural manifestations.

OBJECTIVES

To assess the effects of functional analysis-based interventions for people with dementia (and their caregivers) living in their own home or in other settings.

SEARCH METHODS

We searched ALOIS: the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on 3 March 2011 using the terms: FA, behaviour (intervention, management, modification), BPSD, psychosocial and Dementia.

SELECTION CRITERIA

Randomised controlled trials (RCTs) with reported behavioural outcomes that could be associated with functional analysis for the management of challenging behaviour in dementia.

DATA COLLECTION AND ANALYSIS

Four reviewers selected trials for inclusion. Two reviewers worked independently to extract data and assess trial quality, including bias. Meta-analyses for reported incidence, frequency, severity of care recipient challenging behaviour and mood (primary outcomes) and caregiver reaction, burden and mood were performed. Details of adverse effects were noted.

MAIN RESULTS

Eighteen trials are included in the review. The majority were in family care settings. For fourteen studies, FA was just one aspect of a broad multi-component programme of care. Assessing the effect of FA was compromised by ill-defined protocols for the duration of component parts of these programmes (i.e. frequency of the intervention or actual time spent). Therefore, establishing the real effect of the FA component was not possible.Overall, positive effects were noted at post-intervention for the frequency of reported challenging behaviour (but not for incidence or severity) and for caregiver reaction (but not burden or depression). These effects were not seen at follow-up.

AUTHORS' CONCLUSIONS

The delivery of FA has been incorporated within wide ranging multi-component programmes and study designs have varied according to setting - i.e. family care, care homes and hospital, with surprisingly few studies located in care homes. Our findings suggest potential beneficial effects of multi-component interventions, which utilise FA. Whilst functional analysis for challenging behaviour in dementia care shows promise, it is too early to draw conclusions about its efficacy.

‘The problem with Leonard’: A critical constructionist view of need-driven dementia-compromised behaviours

This critical constructionist case study of ‘Leonard,’ a man with frontotemporal dementia living on a special care unit predominantly populated by people with Alzheimer’s disease and related dementias, explores how healthy others’ perceptions of the prevailing physical and psychosocial environment were influenced by Leonard’s behaviour which, in turn, was influenced by people’s perceptions of him as a ‘problem’. Data were obtained through participant observations, individual interviews with staff and residents, and focus groups with family members and nursing staff. Leonard’s ‘needs-driven dementia-compromised’ behaviours are not recognized as such by many of the healthy others with whom he co-creates his psychosocial environment; rather he is constructed as deviant, which undermines his selfhood as well as his quality of life. Education of staff and family members as well as broad organizational change is needed to address the issues underlying the problems for which Leonard is blamed but instead arise largely from the environment within which Leonard is situated.

Psychometric evaluation of a proposed Alzheimer's aggression scale

The purpose of this study was to evaluate a popular measure of Alzheimer's disease (AD) memory and behavior problems and to determine whether its aggressive behavior items coalesced empirically as a subscale to form a psychometrically viable AD aggression measure for clinicians. Data from self-report questionnaires were examined from 419 informal AD caregivers in the southern United States. Principal axis factoring revealed a unidimensional solution with robust item loadings on the single factor. Three forms of reliability analysis indicated moderately strong internal consistency on this proposed measure. Evidence of convergent validity analysis was suggested via the measure's significant correlations to theoretically linked constructs. The proposed measure emerged as a reliable and valid tool for health care practitioners for the appraisal of problematic AD aggression behaviors from the caregiver perspective.

Care home design for people with dementia: What do people with dementia and their family carers value?

OBJECTIVES

To report on the views of people with dementia who live in care homes and their family carers on aspects of design that are important to them, and discuss these in relation to developing physical care environments that respond to the wishes of people with dementia and their family carers.

METHOD

Six focus groups were held: two in Northern Ireland and four in Scotland. A total of 40 people participated in the focus groups. Twenty nine people were with dementia (24 female and five male), and 11 were family carers (10 female and one male).

RESULTS

Carers discussed the features of a building they took into account when selecting a care home, and discussed this in relation to 'bricks and mortar versus people'. Key themes reported by people with dementia and their family carers included how the space in the environment is used, for example, what happens in the building and the presence or absence of certain design features. Outside space and wayfinding aids were identified as positive features of the home, along with a general lack of concern about ensuite provision.

CONCLUSION

The results demonstrate the complexity of building design as it must provide living space acceptable to people with dementia living there and family members who visit, as well as provide a workable environment for staff. The findings highlight areas that should be considered by care home teams involved in the build of a new home or the redevelopment of an existing care home.

Self-injurious behavior in the nursing home setting

BACKGROUND

Self-injurious behavior (SIB) in older adults is defined as harm inflicted on oneself without conscious suicidal intent. SIB as a separate entity distinct from suicidal intent is poorly understood. However, it is of great concern to the patients' families and caregivers and it poses serious clinical challenges for clinicians.

METHODS

We searched the database of PubMed, Ovid Medline, and ScienceDirect for reports published between 1970 and 2009 using combination of the following keywords: "self-injurious behavior", "self-destructive behavior", "self-mutilating behavior", "older adults", "geriatric population", and "nursing homes". The term "self-harm behavior" which also appears in the literature is broader in scope than "self-injurious behavior". It encompasses high suicide intent and failed suicide attempts; therefore, we excluded this term in order to focus purely on "self-injurious behavior". Our search yielded 10 publications concerning SIB in older adults, four of which included studies investigating SIB in nursing homes.

RESULTS

Clinical studies of SIB in older adult nursing home residents are sparse. This limited literature suggests that SIB is a prevalent phenomenon and is reported to be as high as 14% in one study of nursing home subjects aged 65 and older. It is reported to be strongly associated with dementia and a risk of accidental death. It has been suggested that SIB among demented patients occurs in the context of poor impulse control and physical isolation.

CONCLUSION

SIB is likely a common phenomenon in older adult nursing home residents. There is little evidence-based treatment guidance for SIB in older population.

Long-term care for people with dementia: environmental design guidelines

BACKGROUND

A large and growing number of people with dementia are being cared for in long-term care. The empirical literature on the design of environments for people with dementia contains findings that can be helpful in the design of these environments. A schema developed by Marshall in 2001 provides a means of reviewing the literature against a set of recommendations. The aims of this paper are to assess the strength of the evidence for these recommendations and to identify those recommendations that could be used as the basis for guidelines to assist in the design of long term care facilities for people with dementia.

METHODS

The literature was searched for articles published after 1980, evaluating an intervention utilizing the physical environment, focused on the care of people with dementia and incorporating a control group, pre-test-post-test, cross sectional or survey design. A total of 156 articles were identified as relevant and subjected to an evaluation of their methodological strength. Of these, 57 articles were identified as being sufficiently strong to be reviewed.

RESULTS

Designers may confidently use unobtrusive safety measures; vary ambience, size and shape of spaces; provide single rooms; maximize visual access; and control levels of stimulation. There is less agreement on the usefulness of signage, homelikeness, provision for engagement in ordinary activities, small size and the provision of outside space.

CONCLUSIONS

There is sufficient evidence available to come to a consensus on guiding principles for the design of long term environments for people with dementia.

Validation of the Chinese Challenging Behaviour Scale: clinical correlates of challenging behaviours in nursing home residents with dementia

BACKGROUND

Behavioural and psychological symptoms of dementia (BPSD) are associated with considerable burden to patients with dementia and their caregivers. Formal caregivers in residential care settings face different challenges when delivering care.

OBJECTIVE

This study aimed at assessing the clinical correlates of challenging BPSD using the Chinese version of the Challenging Behaviour Scale (CCBS) designed for residential care settings.

METHODS

One hundred and twenty-five participants were recruited from three care-and-attention homes in Hong Kong. The CCBS was administered together with the Cantonese version of Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), Disability Assessment for Dementia (DAD) and Neuropsychiatric Inventory (NPI) to explore the relationships between challenging behaviour and important clinical correlates.

RESULTS

The CCBS had good internal consistency (alpha = 0.86), inter-rater (ICC = 0.79) and test-retest reliability (ICC = 0.98). A four-factor structure is demonstrated by factor analysis: hyperactivity behaviours, hypoactivity behaviours, verbally aggressive and aberrant behaviours. Challenging behaviours were associated with male gender, cognitive impairment, functional disability, neuropsychiatric symptoms, and higher caregiver's workload.

CONCLUSIONS

The CCBS is a valid and reliable measure to assess BPSD in residential care settings in local Chinese community. It is useful in evaluating the challenges faced by formal caregivers during daily care of the dementia patients.

Self-injurious behaviour in nursing home residents with dementia

OBJECTIVE

To explore the phenomenology and prevalence of Self-Injurious Behaviour (SIB) in nursing home patients with dementia.

METHOD

Cross-sectional study of 110 nursing home patients with dementia. Nurses' ratings of SIB and other behavioural disturbances were compared to independent resident physician ratings of medical charts data pertaining to dementia type, dementia severity, prescribed psychotropic drugs, immobility and measures to restrain the patient. Instruments used were the Overt Aggression Scale (OAS, modified), Behaviour Rating Scale for Psychogeriatric Inpatients (GIP), Rating scale for Older Patients (BOP).

RESULTS

SIB was observed in 22% of the dementia patients. Pinching or scratching oneself and banging one's fist against objects were most frequently reported. Five patients showed a combination of two types of SIB. As expected, SIB was modestly related to Aimless repetitive behaviour and Aggression and no association was found between SIB and Apathy. Correlates of SIB were prescribed psychotropics (i.e. benzodiazepines), immobility and measures to restrain the patient.

CONCLUSIONS

Preliminary data suggest that SIB is a specific psychopathological phenomenon that is highly prevalent in nursing home patients with dementia. Future research should focus on the aetiology and treatment of SIB.
