Physical environmental designs in residential care to improve quality of life of older people

Delivery of Neuropsychological Interventions for Adult and Older Adult Clinical Populations: An Australian Expert Working Group Clinical Guidance Paper

Delivery of neuropsychological interventions addressing the cognitive, psychological, and behavioural consequences of brain conditions is increasingly recognised as an important, if not essential, skill set for clinical neuropsychologists. It has the potential to add substantial value and impact to our role across clinical settings. However, there are numerous approaches to neuropsychological intervention, requiring different sets of skills, and with varying levels of supporting evidence across different diagnostic groups. This clinical guidance paper provides an overview of considerations and recommendations to help guide selection, delivery, and implementation of neuropsychological interventions for adults and older adults. We aimed to provide a useful source of information and guidance for clinicians, health service managers, policy-makers, educators, and researchers regarding the value and impact of such interventions. Considerations and recommendations were developed by an expert working group of neuropsychologists in Australia, based on relevant evidence and consensus opinion in consultation with members of a national clinical neuropsychology body. While the considerations and recommendations sit within the Australian context, many have international relevance. We include (i) principles important for neuropsychological intervention delivery (e.g. being based on biopsychosocial case formulation and person-centred goals); (ii) a description of clinical competencies important for effective intervention delivery; (iii) a summary of relevant evidence in three key cohorts: acquired brain injury, psychiatric disorders, and older adults, focusing on interventions with sound evidence for improving activity and participation outcomes; (iv) an overview of considerations for sustainable implementation of neuropsychological interventions as 'core business'; and finally, (v) a call to action.

Impact of an improved outdoor space on people with dementia in a hospital unit

Introduction

Gardens and outdoor spaces are an important part of institutional environments for people with dementia. However, evidence regarding the benefits these spaces have for people with dementia is still limited. This paper presents the evaluation of the redevelopment of an inaccessible outdoor space into a therapeutic garden on a high dependency psychogeriatric unit in an acute hospital.

Method

A Mixed methods evaluation was undertaken. An interrupted time series analysis investigated the impact of the garden on falls and challenging behaviours of patients using routinely collected data. Perspectives of the redeveloped garden were captured through (a) a staff survey and (b) semi-structured interviews with families of patients.

Results

Rates of falls and challenging behaviours dropped at the time of the garden opening but showed increasing rates each month both before and after the garden opened. Most staff believed that the garden provided benefits for patients however limited staff time and concerns over patient safety were barriers to use. Families identified four main themes related to garden use including: (1) being outside (2) occupation and identity, (3) being stimulating, and (4) barriers and facilitators.

Conclusion

The garden was regarded positively by families and staff however, there were barriers that prevented it from being better utilised. Staff concerns over risk were not reflected in falls and challenging behaviour outcomes. Further research into how barriers to garden use may be overcome is justified.

'It's like home' - A small-scale dementia care home and the use of technology: A qualitative study

AIM

To explore the experiences of residents, families and staff in the establishment of a new small-scale home model of care for people living with dementia.

BACKGROUND

New and innovative small-scale models of care have the potential to improve outcomes for older people, especially those with dementia, who experience high rates of cognitive impairment in traditional residential aged care homes in Australia.

DESIGN

A qualitative descriptive study.

METHODS

Semi-structured interviews with 14 guests, family and staff of a new small-scale dementia home named 'Kambera House' in the Australian Capital Territory were conducted between July 2021 when the home opened and August 2022. Data were analysed using reflexive thematic analysis and reported according to the COREQ guidelines.

RESULTS

Two guests with mild-to-moderate dementia, five family and seven staff members participated in the study. The data revealed high satisfaction with Kambera House, generating five themes. Falls detection technology in the home provided a sense of safety, enabling more time for person-centred care. Free, everyday technology connected the home with families as part of an overall community of care where staff were empowered to maximize choice and dignity of risk of guests living in the home. This contributed to the sense of community, rather than an institution, where the conditions of work supported the conditions of care, and were embedded in a culture of responsiveness, change and flexibility.

CONCLUSION

Kambera House represents a successful example of a new small-scale dementia home. Technology played an important background role in improving overall safety and flexibility as part of a model of care which demonstrated positive experiences for guests and families by being responsive to their individual needs.

IMPACTS

Small-scale homes for people with dementia offer an alternative model that may provide more individualized, person-centred care compared with the traditional institutionalized care.

Methods for the involvement of people living with dementia in research focused on the built environment: a protocol for a scoping review

INTRODUCTION

The positive influence of a well-designed built environment in dementia-specific care has been known for several years. Many studies focusing on the built environment have captured the perspectives of people living with dementia. However, it remains unclear to what degree and with which methods these individuals have been actively involved in research especially when attempting to understand their perspective. The planned scoping review aims to (1) synthesise methods and results from research about the built environment according to active involvement of people living with dementia and (2) describe facilitators and barriers to this active involvement to capture their perspectives in research.

METHODS AND ANALYSIS

We will use four search strategies: (1) searches in academic databases MEDLINE via PubMed, CINAHL and APA PsycINFO via EBSCO, and Scopus; (2) grey literature searches via Google Scholar; (3) handsearches of non-academic environmental planning and design journals and (4) identifying other publications of key authors in the field. Additionally, backward and forward citation tracking will be performed via reference lists and Google Scholar, respectively. Relevant literature published between 2013 and 2023 will be identified for data extraction and synthesis. One researcher will perform each strategy. Title-abstract/full text-screening will be conducted using Covidence by two researchers. Results will be displayed in a table and through figures illustrating identified facilitators and barriers.

ETHICS AND DISSEMINATION

We raised no ethical concerns for the planned scoping review. We will prepare the findings including the identified barriers with long-term care practitioners from our network to identify how changes in practical application methods can be addressed. This dialogue can serve as a basis for including people living with dementia to discuss highlighted barriers when researching their perspectives on the built environment. The scoping review results will be reported in both academic and non-academic journals and at academic conferences.

Impact of relational continuity of primary care in aged care: a systematic review

Background

Greater continuity of care has been associated with lower hospital admissions and patient mortality. This systematic review aims to examine the impact of relational continuity between primary care professionals and older people receiving aged care services, in residential or home care settings, on health care resource use and person-centred outcomes.

Methods

Systematic review of five databases, four trial registries and three grey literature sources to October 2020. Included studies (a) aimed to increase relational continuity with a primary care professional, (b) focused on older people receiving aged care services (c) included a comparator and (d) reported outcomes of health care resource use, quality of life, activities of daily living, mortality, falls or satisfaction. Cochrane Collaboration or Joanna Briggs Institute criteria were used to assess risk of bias and GRADE criteria to rate confidence in evidence and conclusions.

Results

Heterogeneity in study cohorts, settings and outcome measurement in the five included studies (one randomised) precluded meta-analysis. None examined relational continuity exclusively with non-physician providers. Higher relational continuity with a primary care physician probably reduces hospital admissions (moderate certainty evidence; high versus low continuity hazard ratio (HR) 0.94; 95% confidence interval (CI) 0.92–0.96, n = 178,686; incidence rate ratio (IRR) 0.99, 95%CI 0.76–1.27, n = 246) and emergency department (ED) presentations (moderate certainty evidence; high versus low continuity HR 0.90, 95%CI 0.89–0.92, n = 178,686; IRR 0.91, 95%CI 0.72–1.15, n = 246) for older community-dwelling aged care recipients. The benefit of providing on-site primary care for relational continuity in residential settings is uncertain (low certainty evidence, 2 studies, n = 2,468 plus 15 care homes); whilst there are probably lower hospitalisations and may be fewer ED presentations, there may also be an increase in reported mortality and falls. The benefit of general practitioners’ visits during hospital admission is uncertain (very low certainty evidence, 1 study, n = 335).

Conclusion

Greater relational continuity with a primary care physician probably reduces hospitalisations and ED presentations for community-dwelling aged care recipients, thus policy initiatives that increase continuity may have cost offsets. Further studies of approaches to increase relational continuity of primary care within aged care, particularly in residential settings, are needed.

Physical environmental designs in residential care to improve quality of life of older people

BACKGROUND

The demand for residential aged care is increasing due to the ageing population. Optimising the design or adapting the physical environment of residential aged care facilities has the potential to influence quality of life, mood and function.

OBJECTIVES

To assess the effects of changes to the physical environment, which include alternative models of residential aged care such as a 'home-like' model of care (where residents live in small living units) on quality of life, behaviour, mood and depression and function in older people living in residential aged care.

SEARCH METHODS

CENTRAL, MEDLINE, Embase, six other databases and two trial registries were searched on 11 February 2021. Reference lists and grey literature sources were also searched.

SELECTION CRITERIA

Non-randomised trials, repeated measures or interrupted time series studies and controlled before-after studies with a comparison group were included. Interventions which had modified the physical design of a care home or built a care home with an alternative model of residential aged care (including design alterations) in order to enhance the environment to promote independence and well-being were included. Studies which examined quality of life or outcomes related to quality of life were included. Two reviewers independently assessed the abstracts identified in the search and the full texts of all retrieved studies.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data, assessed the risk of bias in each included study and evaluated the certainty of evidence according to GRADE criteria. Where possible, data were represented in forest plots and pooled.

MAIN RESULTS

Twenty studies were included with 77,265 participants, although one large study included the majority of participants (n = 74,449). The main comparison was home-like models of care incorporating changes to the scale of the building which limit the capacity of the living units to smaller numbers of residents and encourage the participation of residents with domestic activities and a person-centred care approach, compared to traditional designs which may include larger-scale buildings with a larger number of residents, hospital-like features such as nurses' stations, traditional hierarchical organisational structures and design which prioritises safety. Six controlled before-after studies compared the home-like model and the traditional environment (75,074 participants), but one controlled before-after study included 74,449 of the participants (estimated on weighting). It is uncertain whether home-like models improve health-related quality of life, behaviour, mood and depression, function or serious adverse effects compared to traditional designs because the certainty of the evidence is very low. The certainty of the evidence was downgraded from low-certainty to very low-certainty for all outcomes due to very serious concerns due to risk of bias, and also serious concerns due to imprecision for outcomes with more than 400 participants. One controlled before-after study examined the effect of home-like models on quality of life. The author stated "No statistically significant differences were observed between the intervention and control groups." Three studies reported on global behaviour (N = 257). One study found little or no difference in global behaviour change at six months using the Neuropsychiatric Inventory where lower scores indicate fewer behavioural symptoms (mean difference (MD) -0.04 (95% confidence interval (CI) -0.13 to 0.04, n = 164)), and two additional studies (N = 93) examined global behaviour, but these were unsuitable for determining a summary effect estimate. Two controlled before-after studies examined the effect of home-like models of care compared to traditional design on depression. After 18 months, one study (n = 242) reported an increase in the rate of depressive symptoms (rate ratio 1.15 (95% CI 1.02 to 1.29)), but the effect of home-like models of care on the probability of no depressive symptoms was uncertain (odds ratio 0.36 (95% CI 0.12 to 1.07)). One study (n = 164) reported little or no difference in depressive symptoms at six months using the Revised Memory and Behaviour Problems Checklist where lower scores indicate fewer depressive symptoms (MD 0.01 (95% CI -0.12 to 0.14)). Four controlled before-after studies examined function. One study (n = 242) reported little or no difference in function over 18 months using the Activities of Daily Living long-form scale where lower scores indicate better function (MD -0.09 (95% CI -0.46 to 0.28)), and one study (n = 164) reported better function scores at six months using the Interview for the Deterioration of Daily Living activities in Dementia where lower scores indicate better function (MD -4.37 (95% CI -7.06 to -1.69)). Two additional studies measured function but could not be included in the quantitative analysis. One study examined serious adverse effects (physical restraints), and reported a slight reduction in the important outcome of physical restraint use in a home-like model of care compared to a traditional design (MD between the home-like model of care and traditional design -0.3% (95% CI -0.5% to -0.1%), estimate weighted n = 74,449 participants at enrolment).  The remaining studies examined smaller design interventions including refurbishment without changes to the scale of the building, special care units for people with dementia, group living corridors compared to a non-corridor design, lighting interventions, dining area redesign and a garden vignette.

AUTHORS' CONCLUSIONS

There is currently insufficient evidence on which to draw conclusions about the impact of physical environment design changes for older people living in residential aged care. Outcomes directly associated with the design of the built environment in a supported setting are difficult to isolate from other influences such as health changes of the residents, changes to care practices over time or different staff providing care across shifts. Cluster-randomised trials may be feasible for studies of refurbishment or specific design components within residential aged care. Studies which use a non-randomised design or cluster-randomised trials should consider approaches to reduce risk of bias to improve the certainty of evidence.
