Residential Environments for Older Persons: A Comprehensive Literature Review (2005-2022)

BACKGROUND

Independent noninstitutional and institutional residential long-term care environments for older persons have been the subject of significant empirical and qualitative research in the 2005-2022 period. A comprehensive review of this literature is reported, summarizing recent advancements in this rapidly expanding body of knowledge.

PURPOSE AND AIM

This comprehensive review conceptually structures the recent literature on environment and aging to provide conceptual clarity and identify current and future trends.

METHOD AND RESULT

Each source reviewed was classified as one of the five types-opinion piece/essay, cross-sectional empirical investigation, nonrandomized comparative investigation, randomized study, and policy review essay-within eight content categories: community-based aging in place; residentialism; nature, landscape, and biophilia; dementia special care units; voluntary/involuntary relocation; infection control/COVID-19, safety/environmental stress; ecological and cost-effective best practices; and recent design trends and prognostications.

CONCLUSIONS

Among the findings embodied in the 204 literature sources reviewed, all-private room long-term care residential units are generally safer and provide greater privacy and personal autonomy to residents, the deleterious impacts of involuntary relocation continue, family engagement in policy making and daily routines has increased, multigenerational independent living alternatives are increasing, the therapeutic role of nature and landscape is increasingly well-documented, ecological sustainability has increased in priority, and infection control measures are of high priority in the wake of the coronavirus pandemic. Discussion of the results of this comprehensive review sets the stage for further research and design advancements on this subject in light of the rapid aging of societies around the globe.

A Conceptual Framework for Blockchain Enhanced Information Modeling for Healing and Therapeutic Design

In the face of the health challenges caused by the COVID-19 pandemic, healing and therapeutic design (HTD) as interventions can help with improving people’s health. It is considered to have great potential to promote health in the forms of art, architecture, landscape, space, and environment. However, there are insufficient design approaches to address the challenges during the HTD process. An increased number of studies have shown that emerging information modeling (IM) such as building information modeling (BIM), landscape information modeling (LIM), and city information modeling (CIM) coupled with blockchain (BC) functionalities have the potential to enhance designers’ HTD by considering important design elements, namely design variables, design knowledge, and design decision. It can also address challenges during the design process, such as design changes, conflicts in design requirements, the lack of design evaluation tools and frameworks, and incomplete design information. Therefore, this paper aims to develop a conceptual BC enhanced IM for HTD (BC-HTD) framework that addresses the challenges in the HTD and promotes health and well-being. The structure of BC-HTD framework is twofold: (1) a conceptual high-level framework comprising three levels: user; system; and information, (2) a conceptual low-level framework of detailed content at the system level, which has been constructed using a mixed quantitative and qualitative method of literature analysis, and validated via a pre-interview questionnaire survey and follow-up interviews with industry experts and academics. This paper analyzes the process of BC enhanced HTD and the knowledge management of HTD to aid design decisions in managing design information. This paper is the first attempt to apply the advantages of BC enabled IM to enhance the HTD process. The results of this study can foster and propel new research pathways and knowledge on the value of design in the form of non-fungible token (NFT) based on the extended advantages of BC in the field of design, which can fully mobilize the healing and therapeutic behaviors of designers and the advantage potential of HTD to promote health, and realize the vision of Health Metaverse in the context of sustainable development.

Japanese Translation and Validation of the Environmental Assessment Tool-Higher Care

OBJECTIVE

The purpose of this study was to translate the Environmental Assessment Tool-Higher Care (EAT-HC) into Japanese and validate its use in small-scale group living facilities in Japan.

BACKGROUND

Environment of a facility is shown to improve its residents' quality of life (QOL). Japan's "welfare-based nursing homes for the elderly" are gradually shifting to a small-scale group living concept called group care units (GCUs). However, there is no appropriate environmental tool available for evaluating GCUs. The application of valid environmental assessment tools brings about a better understanding of the nature of good environments and the relationship between environments and outcomes for residents living with dementia.

METHODS

The study had a mixed method design conducted in several steps, covering translation and adaptation. The translation phase involved (1) forward translation and (2) backward translation. The adaptation phase involved (3) content validity and homogeneity reliability and (4) concurrent validity and interrater reliability.

RESULTS

71 Items (92%) met the acceptable level of content validity (item-content validity index [CVI] > .79) and had good scale-CVI of .88. Concurrent validity was confirmed between .65 and .78 (p < .001). For reliability test, the internal consistency of six subscales was between .88 and .98. Overall interobserver agreement was 90.3%. Intraclass correlation coefficients were .80-.98 (p < .001), and homogeneity reliability coefficient for all items was >.76 (p < .01).

CONCLUSIONS

Validation of the EAT-HC-Japanese Version (EAT-HC-JV) was confirmed as an appropriate tool for environmental assessment to enhance the QOL in Japan's GCUs. For future study, we plan to modify the EAT-HC-JV to adapt to Japanese cultural aspects in order to increase its usability in Japan.

Staff perspectives on the role of physical environment in long-term care facilities on dementia care in Canada and Sweden

OBJECTIVES

This study aimed to explore staff perspectives of the physical environment in supporting their care practices for residents living with dementia in Canadian and Swedish long-term care facilities.

DESIGN

An exploratory, descriptive, qualitative research design based on focus groups was used.

PARTICIPANTS

A total of 24 staff members who worked closely with the residents such as nurses or care aides participated in the focus group interviews from four facilities, two in Sweden and two in Canada.

MEASUREMENTS

Focus group interview was held at each selected care facility once and a total of four times were conducted. Broad questions were asked about the effect of physical environment on care practice, job satisfaction, and interaction with residents. Data were analyzed by thematic analysis.

FINDINGS

This study identified three environmental themes that have substantial effect on the social interaction and care practice: (i) design ambience enables and limits social and care interaction, (ii) space arrangements facilitate and hinder the effectiveness of care delivery, and (iii) sensory stimuli have direct impact on residents. The findings demonstrate that well-designed environment qualities such as homelike ambience, an open layout, and stimulating courtyard positively stimulate the emotion of staff as well as residents, which also leads to build trust and relationship and to increase job satisfaction. The study found that the appropriate level of sound or familiar music for residents with dementia is a positive stimulus. When the staff felt comfortable and supported by good care unit's ambience, they can be motivated to care for their residents, leading to better care practices. The study also found that the closed floor plan in an institutional setting could increase staff fatigue by obstructing the view of residents' behaviors and movement and by increasing walking loads.

CONCLUSIONS

This study highlights the complexities of how care was organized and influenced by the physical environment of the setting. The variations in the physical environmental characteristics and quality of care suggest the value of comparative research in identifying and exploring the possible causes and consequences. Future development in long-term care facilities requires a better understanding of staff experiences and staff involvement in the physical design of care settings.

Understanding the Barriers and Enablers to Using Outdoor Spaces in Nursing Homes: A Systematic Review

BACKGROUND AND OBJECTIVES

Despite acknowledged benefits of residents in nursing homes spending time outdoors, little is known about factors related to their use of outdoor space. This systematic review summarizes reported barriers and enablers to nursing home residents' use of outdoor spaces.

RESEARCH DESIGN AND METHODS

Multiple databases were searched to May 2018. Qualitative or mixed methods studies describing barriers/enablers to use of outdoor areas by residents of nursing homes (aged 65 years and older), as reported by residents, staff, or family members were included. Study quality rating, thematic analysis, and stratified analyses were performed and confidence in findings assessed using GRADE-CERQual.

RESULTS

Twenty-four studies were included. Nineteen collected data from residents, 15 from staff/caregivers, 7 from families. Major themes and key findings concerned: design of the outdoor area (importance of garden greenery and built features), safety concerns and staffing issues, weather and seasons (appropriate shade and shelter), design of the main building (easy to open doors and nearby access points) and social activities.

CONCLUSIONS AND IMPLICATIONS

Providing gardens with seasonal plants and interactive features, weather protected seating, manageable doors at accessible thresholds, planned social activities, and appropriate clothing are fundamental to facilitate nursing home residents' access to the outdoors. Cultural change at an organizational level, addressing perceptions of safety as a barrier is important. Incorporation of the recommendations in this review by architects, facility managers, and policy makers in the design and management of nursing homes, may increase use of outdoor areas and improve the quality of life of residents.

Is greenery associated with mental health among residents of aged care facilities? A systematic search and narrative review

Objectives: Older adults living in residential aged care facilities (RACFs) may be vulnerable to mental health issues. Evidence suggests greenery is beneficial for adults' mental health in community settings. This review aims to summarise evidence of associations between greenery in RACFs and residents' mental health.Method: Six databases were searched with three sets of terms related to: (1) exposure (e.g. garden, green); (2) outcome (e.g. mental health, well-being); and (3) setting (e.g. aged care, nursing home). The inclusion criteria were peer-reviewed journal articles published in English up to 2017, reporting quantitative/qualitative associations between greenery and mental health in RACFs.Results: Of the nine articles identified, seven reported positive associations between greenery (in particular, garden use) at RACFs and some aspect of residents' mental well-being (e.g. quality of life); however, four out of seven studies used observations and perceptions of staff and relatives. One study examined depression and reported reduction in depression following garden use, while one examined physiological indicators of stress (blood pressure, heart rate) and found no association with garden use. Seven studies examined garden use and four examined the presence of greenery (two examined both exposures).Conclusion: Exposure to greenery and use of greenspace in RACFs show promise for promoting mental health. However, the findings relied mainly on non-validated measures of mental health. More robust evidence based on valid and reliable mental health measures is needed. Future studies also need to examine the effect of visual exposure to greenery and the effect of greenery on stress reduction.

Neighborhood-based subjective environmental vulnerability index for community health assessment: Development, validation and evaluation

Neighborhood-based environmental vulnerability is significantly associated with long-term community health impacts. Previous studies have quantified environmental vulnerability using objective environmental datasets. However, environmental cognition among a population may influence subjective feelings of environmental vulnerability, and this can be associated with community health risk. In this study, a mixed-methods approach was applied to estimate neighborhood-based environmental vulnerability based on objective environmental measures and subjective environmental understanding from a local population. The synergistic use of both qualitative and quantitative data resulted in a "subjective environmental vulnerability" index which can demonstrate environmental deprivation across Hong Kong. The resultant maps were compared with a mortality dataset between 2007 and 2014, based on a case-series analysis. The case-series analysis indicated that using a subjective environmental vulnerability index as an approach for neighborhood mapping is able to estimate the community health risk across Hong Kong. In particular, the following types of cause-specific mortality have significant association with the subjective environmental vulnerability index: 1) mortality associated with mental and behavioral disorders, 2) cardiovascular mortality, 3) respiratory mortality, and 4) mortality associated with diseases of the digestive system. In conclusion, the use of a subjective environmental vulnerability index can be implemented within a community health planning program, especially to reduce long-term adverse impacts on population with mental impairment.

Use of the physical environment to support everyday activities for people with dementia: A systematic review

Difficulty with everyday activities is a key symptom and defining feature of dementia, relating to subjective reports of well-being and overall quality of life. One way to support individuals in their daily activities is by modifying the physical environment to make it easier to interact with during activity performance. This systematic review explores the range of studies available using physical environmental strategies to support performance in everyday activities for people with dementia. Seventy-two relevant studies were identified by the search. Physical environmental strategies included changes to the global environment and to architectural features, use of moveable environmental aids and tailored individual approaches. Strategies supported general everyday activity functioning (N = 19), as well as specific activities, particularly mealtimes (N = 15) and orientation in space (N = 16); however, few studies were found that focused on aspects of personal care such as dressing (N = 1) and showering or the preferred hobbies of individuals (N = 0). Overall, there appeared to be a lack of research within private home environments, and of studies which specify the dementia syndrome or the whole neuropsychological profile of people with dementia. More work is needed to extend theoretical understandings of how people with dementia interact with their environments so that these spaces can be designed to further support activities of daily living performance. Future work in this field could also incorporate the perspectives and preferences of those living with dementia.

The conduct and process of mental capacity assessments in home health care settings

The assessment of capacity to consent to treatment is key to shared practitioner-patient decision-making. It is the responsibility of the person closest to the decision being made to carry out the assessment. The aim was to examine the factors that influence mental capacity assessments in home health care settings and identify the facilitators and inhibitors to the conduct and process of assessments as perceived and experienced by non-medical health practitioners providing generalist community services. Semi-structured interviews with a purposive sample of community nurses, community physiotherapists and community occupational therapists in one NHS Trust in London. Data were analysed thematically. The main themes were issues relating to: intrinsic patient factors and behaviours; recognising, managing and utilising the influence of the family; practitioner motivation and competence; working together as a team to optimise shared decision making, and; the importance of place. While some issues appear germane to both hospital and home health care settings, others are unique to - or manifest very differently in - home health care settings. The findings suggest that the influence of family members, long-term practitioner-patient relationships and physical distance from co-workers make the conduct and process of mental capacity assessments in home health care settings an inherently complex endeavour.

Concept mapping to improve team work, team learning and care of the person with dementia and behavioural and psychological symptoms

The incidence of behavioural and psychological symptoms of dementia in residential aged care facilities is high. Effective team work and knowledgeable staff are cited as important facilitators of appropriate care responses to clients with these symptoms, but to achieve this within a resource-poor workplace can be challenging. In the study reported in this paper, concept mapping was trialled to enhance multifocal person-centred assessment and care planning as well as team learning. The outcomes of team concept mapping were evaluated using a quasi-experimental design with pre- and post-testing in 11 selected Australian residential aged care facilities , including two control residential aged care facilities , over a nine-month period. It was demonstrated that use of concept mapping improved team function, measured as effectiveness of care planning, as well as enhancing learning, with increased knowledge of dementia care even amongst staff who were not directly involved with the process. It is suggested that these results may be generalizable to other countries and care settings.

Field observations into the environmental soul: spatial configuration and social life for people experiencing dementia

This article focuses on the important, facilitating role architectural design plays in social interaction within long-term care facilities (LTCFs) serving people with dementia. Here, we apply space syntax, a set of theories and techniques for the analysis of spatial configurations, as an objective measure of environmental characteristics. Almost 150 rounds of behavioral observations were collected in the social spaces of 3 LTCFs. Using the visibility and proximity metrics of space syntax, the locations of occurrence of various social activities in relation to the furniture and spatial layout on architectural floor plans have been identified. The results did not confirm the space syntax hypothesis that spaces with greater visibility and proximity promote more social interaction. Further analysis revealed that when in settings with better visibility and accessibility, the residents were more likely to engage in low levels of interaction. High-level social interactions actually were more likely to occur in settings providing greater privacy (eg, less visibility and accessibility). The findings suggest an important nuance that architectural configuration factors impact not only the likelihood but also the type of conversations likely to occur in certain locations. This would have implications for both design and staff training on how best to utilize social spaces for therapeutic effect, particularly within the context of person-centered care.

Cognitive rehabilitation for elderly people with early-stage Alzheimer's disease

[Purpose] The purpose of this study was to investigate the effect of cognitive rehabilitation including tasks of cognitive training on performance of everyday activities in elderly people with early-stage Alzheimer’s disease. [Subjects and Methods] Forty-three elderly people (15 men, 28 women) with a diagnosis of Alzheimer’s disease who had a Mini-Mental State Examination (MMSE) score of 18 or above were randomly assigned to two groups: the cognitive rehabilitation group (experimental) and control group. This study used a randomized controlled trial design. Cognitive rehabilitation is consisted of 8 sessions, each lasting 60 minutes (individual 30 min, group 30 min). The eight weekly individual sessions of cognitive rehabilitation were performed consisting of an individualized intervention focusing on a personally meaningful goal. The eight weekly group sessions involved practicing time-and-place orientation, matching faces and names, and learning memory and sustaining attention. [Results] Significant improvements were observed in rating of occupation performance and satisfaction, Quality of Life in Alzheimer’s Disease (QOL-AD), and the orientation subscale of the MMSE in the experimental group, whereas participants in the control group did not show any significant difference in any tests between before and after the intervention. [Conclusion] Cognitive rehabilitation including tasks of cognitive training is an effective intervention for improving performance and satisfaction with respect to activities of daily living and specific cognitive functions.

A systematic review--physical activity in dementia: the influence of the nursing home environment

Most older persons with dementia living in nursing homes spend their days without engaging in much physical activity. This study therefore looked at the influence that the environment has on their level of physical activity, by reviewing empirical studies that measured the effects of environmental stimuli on the physical activity of nursing home residents suffering from dementia. The electronic databases PubMed, PsycINFO, EMBASE, CINAHL and the Cochrane Library were used for the search. The search covered studies published between January 1993 and December 2012, and revealed 3187 abstracts. 326 studies were selected as potentially relevant; of these, 24 met all the inclusion criteria. Positive results on the residents' levels of physical activity were found for music, a homelike environment and functional modifications. Predominantly positive results were also found for the small-scale group living concepts. Mixed results were found for bright or timed light, the multisensory environment and differences in the building footprint.

Exploring staff perceptions on the role of physical environment in dementia care setting

This study explored staff perceptions of the role of physical environment in dementia care facilities in affecting resident’s behaviors and staff care practice. We conducted focus groups with staff (n = 15) in two purposely selected care facilities in Vancouver, Canada. Focus group participants included nurses, care aides, recreation staff, administrative staff, and family. Data analysis revealed two themes: (a) a supportive physical environment contributes positively to both quality of staff care interaction and residents’ quality of life and (b) an unsupportive physical environment contributes negatively to residents’ quality of life and thereby makes the work of staff more challenging. The staff participants collectively viewed that comfort, familiarity, and an organized space were important therapeutic resources for supporting the well-being of residents. Certain behaviors of residents were influenced by poor environmental factors, including stimulation overload, safety risks, wayfinding challenge, and rushed care. This study demonstrates the complex interrelationships among the dementia care setting’s physical environment, staff experiences, and residents’ quality of life.

Needs of people with dementia in long-term care: a systematic review

With the aging of the population and the projected increase of dementia in the coming years, it is crucial that we understand the needs of people with dementia (PWD) in order to provide appropriate care. The aim of this study is to determine, using the best evidence possible, the care needs of PWD living in long-term care (LTC). A total of 68 studies, published between January 2000 and September 2010, were identified from six databases. From the selected studies, 19 needs of PWD were identified. The existing evidence suggests that psychosocial needs such as the need to engage in daily individualized activities and care must not be ignored in LTC. This review aims to provide a clearer picture of the needs of this growing patient population.

Staff and relatives' perspectives on the aggressive behaviour of older people with dementia in residential care: a qualitative study

Staff and relative perspectives on patient aggression in dementia care units are seriously under researched in the U.K. Any work that has been conducted has relied upon quantitative studies. Qualitative research on aggression management in older peoples services are rare. In-depth views that can offer insights into causation and management strategies are therefore under represented in the literature. In order to investigate this issue further we interviewed a number of nursing staff and relatives in four U.K. care homes in the North West of England. Using a combined approach of one-to-one interviews (for staff) and focus groups (for relatives) we explored their views as to the reasons for and ways of responding to aggressive behaviour. This was part of a larger study reported upon elsewhere. Using thematic analysis we found similar results from both staff and relatives and as such their views were categorized into two broad areas: causation and management. In regards to causation we noted three sub-themes; internal, external and interpersonal factors which are further subdivided in the paper and for management two broad categories: the compassionate approach and 'don't go in strong'. The results indicated that staff in the participating units embraced a person-centred approach to aggression management. They predominantly respond to aggressive incidents with interpersonal strategies, such as distraction as opposed to medication or restraint. Overall they adopt a person centre approach to patient care. Relatives were clear in their perceptions of aggression as an interpersonal challenge, which is compounded or mediated by the illness of dementia. Consequently they were positive in their views of staff using non-coercive interventions. While the results of this and our earlier study are promising suggesting a less invasive approach to this aspect of dementia care, given the limitations of a small sample, more research of a similar nature is warranted. Findings from multidimensional studies can then provide a sounder basis for health and social care education, and person centred informed practice to reduce the incidence of aggression through preventative strategies.

Special care units and traditional care in dementia: relationship with behavior, cognition, functional status and quality of life - a review

Background

Special care facilities for patients with dementia gain increasing attention. However, an overview of studies examining the differences between care facilities with respect to their effects on behavior, cognition, functional status and quality of life is lacking.

Results

Our literature search resulted in 32 studies published until October 2012. Overall, patients with dementia who lived at special care units (SCUs) showed a significantly more challenging behavior, more agitation/aggression, more depression and anxiety, more cases of global cognitive impairment and a better psychosocial functioning. There was a tendency towards a better functional status in specialized care facilities, and a better quality of life was found in favor of the SCU group compared to the traditional nursing home (n-SCU) group. Longitudinal studies showed an increased number of neuropsychiatric cases, more patients displaying deteriorating behavior and resistance to care as well as less decline in activities of daily living (ADL) in the SCU group compared to the n-SCU group. Patients in small-scale, homelike SCUs showed more agitation and less ADL decline compared to SCU patients.

Conclusion

This review shows that the patient characteristics in SCU and n-SCU settings and, to a minor extent, in SCU and small-scale, homelike SCU settings are different. Over time, there are differences between n-SCU, SCU and small-scale, homelike SCU facilities for some variables.

The staff's view on dementia and the care in three cultures: A qualitative study in France, Portugal and Sweden

This article discusses the staff's view on dementia and its impact on the care delivered arising out of a qualitative comparative study focusing on long-term care of older people in France, Portugal and Sweden. The aim was to explore the staff's view on the illness dementia; on older people suffering from dementia; the care provided and the impact of various views on the care. The care was studied through observations at 22 care settings in the three countries and the staff's attitudes were explored by means of interviews with 79 people. A relation-oriented phenomenological approach was used. Great differences appeared regarding the various staff groups’ views. The findings also indicated that the staff's view; the cultural context and the organizational environment might have an impact on the care provided. However the impact of professional affiliation and the way of collaborating seemed to be of greater significance than other similarities or differences. An interdisciplinary based starting point, with close collaboration between medical based health care and social care of older people suffering from dementia in integrative care models, is therefore of vital importance.

‘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.

Continuity in the midst of change: behaviors of residents relocated from a nursing home environment to small households

A time-sampling procedure was used to observe behaviors of 22 long-term-care residents with dementia (Mini-Mental State Exam median, 11.94; range 0-23) in public areas before and after relocation from a traditional nursing home environment to 2 small household units. Two trained observers noted the occurrence of 19 social behaviors (14 verbal, 5 nonverbal) in which the resident intentionally interacted with another person. Another 19 nonsocial behaviors (16 active, 3 passive) were also coded. Analysis by t tests of 6 groupings of behaviors showed no significant differences before and after relocation, with the exception of nonverbal social interactions. Overall, residents showed consistency in both social and nonsocial behaviors. Results are interpreted in light of personal, social, and environmental continuity despite the many changes associated with the relocation.

Guiding design of dementia friendly environments in residential care settings: Considering the living experiences

In the past twenty years, the importance of the physical and social environments in supporting the person with dementia has gained a much higher profile in dementia care. Despite efforts to move aged care away from the medical model to a more balanced social model of care, we still struggle with the dominance of an institutional context which impedes individuality and choice. This article argues that the experience of the person with dementia should frame the perspective brought to built design and the philosophy of care — in essence, `looking out from the inside'. Shifting the emphasis from condition to experience encourages the culture change needed to create environments that allow the person with dementia to be an active participant in everyday life rather than a passive recipient of care. Based on the development of a resource for residential and respite facilities in Australia, seven living experiences are identified: the presentation of self-experience, eating experience, personal enjoyment experience, bedroom experience, family and community connections experience, end-of-life experience and the staff experience. Each is discussed to show how consideration of the living experiences provides a way to focus thinking for design of the built environment to practically support the person with dementia, thereby addressing the wider spectrum of issues in creating a dementia friendly physical and social environment from the perspective of the person with dementia.
