Alzheimer's disease patients institutionalized in group homes run by long-term care insurance exhibit fewer symptoms of behavioural problems as evaluated by the Behavioural Pathology in Alzheimer's Disease Rating Scale

Factors Associated with Behavioral and Psychological Symptoms of Dementia during COVID-19

(1) Background: Preventive measures to control the spread of COVID-19 are essential, but they often cause social isolation and diminish the physical and mental health of older adults. In cognitively impaired individuals, the pandemic has worsened behavioral and psychological symptoms of dementia (BPSD). Here, we explored the factors contributing to the worsening of BPSD during the COVID-19 pandemic. (2) Methods: Potential patients were identified at a memory clinic in Japan between June 2017 and June 2021. Eligible patients had a diagnosis of mild cognitive impairment (MCI) or dementia during the study period. The outcome was BPSD, as assessed by using the Dementia Behavioral Disorders Scale. Information on patients' lifestyle habits and use of care services was obtained for use as primary explanatory variables; multiple regression analysis was performed to examine the relationship between BPSD and care services use or lifestyle habits. The model was adjusted for sociodemographic factors, and the interaction terms of the pandemic period with lifestyle and service use were included to evaluate the effects of COVID-19. (3) Results: We identified 977 participants with MCI and 1380 with dementia (MCI group: 69.8% age 75 years or older, 54.2% female; dementia group: 79.8% age 75 years or older, 64.8% female). After adjustment for possible confounders, significantly worse BPSD was demonstrated in those who used daycare services during COVID-19 (both MCI and dementia patients; p = 0.007 and p = 0.025 respectively) and in those with poor nutritional function (dementia patients; p = 0.040). (4) Conclusions and Implications: During COVID-19, poor nutritional status and use of daycare services were associated with BPSD in those with cognitive decline. These findings indicate the need to fully examine the quantity and quality of care services for people with cognitive decline during emergencies and to continue to provide effective services.

The Role of the Built Environment on the Quality of Life for Residents in Long-Term Care Facilities in Asia: A Scoping Review

Background and Objectives

The quality of the built environmental features in long-term care (LTC) homes significantly influences residents’ functioning (e.g., wayfinding, self-care, and social interaction) and well-being. There is limited research on the characteristics of the built environment of LTC and its influence on residents’ quality of life in countries in the Asia–Pacific region (e.g., East Asia and South Asia). The older adult population in this region is expected to increase significantly in the coming decades. There are distinctive perceptions of nursing home, nursing home environments, and sociocultural norms in this geographic region. Given this context, a better understanding of the built environment of LTC facilities in this region can inform design professionals and policymakers for evidence-based decision-making. The present study undertakes a scoping review of the empirical research on the characteristics and influence of the built environment of LTC facilities on residents’ quality of life in the Asia–Pacific context.

Research Design and Methods

Online relevant databases were used to identify articles published 2000–2021, from which we selected 33 publications.

Results

Three substantive themes were generated from the synthesis of the selected publications. These themes are (a) perceptions of nursing home, (b) impact of the built environment on residents’ quality of life, and (c) assessment of the LTC built environment.

Discussion and Implications

We identified research gaps in understanding the role of the built environment in nursing homes in the particular geographic context and future research directions. Five planning and design principles for LTC were derived from the synthesis of key findings to inform design professionals and policymakers.

Factors related to suspension of day-care services: an effective program for older users with declined ambulation to reduce care burden

PURPOSE

Day-care services contribute to maintaining the daily living ability of older people cared for at home. This study aimed to detect factors that could impede the continuation of day-care services.

METHODS

We collected clinical data of 132 older users (age = 82.8 ± 7.5 years; male:female = 49:83) utilizing our day-care center from April 2019 to March 2020. We evaluated age, sex, underlying disease, medication, family background, care level, food texture, physical ability, reasons for frequenting day-care centers, and combined medical/nursing care plans. Participants were divided into two groups: continuation (n = 51) and suspension (n = 81). The collected items were evaluated statistically using the chi-square test, Mann-Whitney test, and unpaired t test. Multivariate logistic analysis (forward-backward stepwise selection method) was added to the statistically significant items. Statistical significance was defined as p < 0.05.

RESULTS

The comparison test detected statistical significance in Parkinson disease/Parkinsonism, pain complaints, day-service use, short-stay service use, day-care center use to reduce care burden, physical ability including ambulation, and availability of the major caregiver (p < 0.05). Day-care service use to reduce care burden (odds ratio 5.646, p < 0.05), use of short-stay and day-care services (odds ratio 4.798, p < 0.05), and low independent ambulation (odds ratio 0.585, p < 0.05) were the likely factors for suspended use (percentage of correct classification = 68.5%).

CONCLUSION

An unreplaceable and effective program for day-service and short-stay services to improve the activities of daily living of older users and reduce care burden is required in day-care centers.

Sex differences in the severity of neuropsychiatric symptoms and their relationship with clinico-demographic and psychosocial factors in patients with amnestic mild cognitive impairment and mild Alzheimer's disease

Objectives: We examined differences in the severity of neuropsychiatric symptoms (NPS) according to sex and identified NPS-related clinico-demographic and psychosocial factors among community-living patients with amnestic-mild cognitive impairment (a-MCI) or mild Alzheimer's disease (AD).Method: Overall, 111 patients (44 males, 67 females) with mild a-MCI (n = 64) or mild AD (n = 47) were included. We divided the patients according to sex and compared their clinico-demographic and psychosocial factors, explored the severity of NPS using the subscales from the Neuropsychiatric Inventory-Questionnaire (NPI-Q), and further identified variables related to NPS.Results: Significant differences in several clinico-demographic and psychosocial characteristics were observed between the sexes. The severity of delusions was higher among females (mean, 0.48; SD, 1.60) than males (mean, 0.23; SD, 1.07; p = .02), while the severity of irritability was higher among males (mean, 0.97; SD, 1.92) than females (mean, 0.49; SD, 1.40; p = .03). The severity of delusions among females was related to the duration of cognitive decline (B = 0.37, p = .03), while the severity of irritability among males was related to general cognition (B = -0.40, p = .003).Conclusion: The severity of NPS among patients with a-MCI or mild AD differed according to sex. We identified NPS-related clinico-demographic factors among these patients. Sex differences should be considered when determining the need for NPS interventions.

Agitation in patients with dementia: a systematic review of epidemiology and association with severity and course

OBJECTIVES

More than 90% of individuals with Alzheimer's disease (AD) experience behavioral and neuropsychiatric symptoms (NPS), such as agitation. However, little is known regarding the specific burden of agitation for Alzheimer's patients.

DESIGN

A global systematic literature review was conducted in MEDLINE and Embase for studies of clinical, humanistic, and economic burden of agitation in AD/dementia published from 2006-2016. References of identified papers and related literature reviews were examined. Studies meeting predetermined inclusion criteria for burden of agitation/NPS were summarized.

RESULTS

Eighty papers met the inclusion criteria for burden of agitation in dementia. Wide ranges of agitation prevalence were reported, but few papers provided information on incidence. The association of agitation with AD severity was presented in multiple studies; a few suggested positive association of agitation with mortality.

CONCLUSIONS

High prevalence of agitation is consistent with earlier reports, but several gaps in understanding of agitation in AD need further exploration.

Impact of Outpatient Rehabilitation Service in Preventing the Deterioration of the Care-Needs Level Among Japanese Older Adults Availing Long-Term Care Insurance: A Propensity Score Matched Retrospective Study

Outpatient rehabilitation (OR) and outpatient day long-term care (ODLC) services are frequently used by older adult patients in Japan. However, there is a need to clarify that OR service, which has more rehabilitation professionals than ODLC, has the role of providing rehabilitation. This retrospective study examined the impact of OR services by comparing the two services based on City A data from the care-needs certification survey conducted between 2015 to 2017. We performed a propensity score matched analysis to compare the changes in the care level and function of OR and ODLC users after two years. The results showed that OR users showed a lower deterioration in care levels and less decline in the activities of daily living (ADL) in dementia and adaptation to social life. In the analysis of older adults requiring support, OR users had a lower deterioration in care levels and less decline in the ADL in dementia and behavioral and psychological symptoms than ODLC users did. There was no difference between the two services with respect to older adults requiring long-term care. The OR service has had an increasingly preventive effect on the deterioration of care levels compared to the ODLC service, which was particularly evident in older adults requiring support.

Advantages of different care services for reducing neuropsychiatric symptoms in dementia patients

BACKGROUND

It is assumed that care services effectively reduce behavioural and psychological symptoms of dementia (BPSD). However, it is unclear which care services are effective for reducing specific BPSD. The aim of this study was to clarify which care services were recognized by care specialists as being effective for reducing each of 11 BPSD.

METHODS

We sent unsigned questionnaires to care specialists in Japan. The questionnaires asked specialists to choose from 12 kinds of care services the most, second-most, and third-most effective service for reducing each of 11 BPSD. The most effective service was scored as 3 points, the second-most was 2 points, and the third-most was 1 point. Specialists were also asked to describe why they chose each service. The 12 kinds of care services were categorized into four categories: (i) home-visit; (ii) outpatient; (iii) short-stay; and (iv) facility. Total scores for each category were analyzed using a two-way anova. The reasons care specialists chose each service were analyzed using morphological analysis, and representative reasons were extracted.

RESULTS

A total of 103 questionnaires were returned. Of the four service categories, outpatient services yielded the highest score for reducing apathy (P < 0.001) due to the effectiveness of participating in recreation and receiving stimulation. Facility services yielded the highest score for reducing aberrant motor behaviour (P < 0.001). Short-stay services yielded the lowest score for reducing depression (P < 0.001). For eight other kinds of BPSD, there were no significant differences between home-visit and facility services or between outpatient and facility services.

CONCLUSIONS

Care specialists reported that effective care services for reducing BPSD differed among types of BPSD. In-home care services might be effective at reducing many BPSD except for aberrant motor behaviour, suggesting that greater use of in-home care services might enable people with BPSD to live in their homes for longer.

Characteristics of the built environment for people with dementia in East and Southeast Asian nursing homes: a scoping review

ABSTRACTBackground:This scoping review explores the characteristics of the current built environment used to accommodate people with dementia in East and Southeast Asia. It is structured around the eight principles of design found in the Environmental Audit Tool High-Care. In addition, the review examines the level of knowledge and other influences contributing to the development of nursing homes in the region.

METHODS

The review was carried out utilizing the methodological framework recommended by Arksey and O'Malley. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses provided an overarching structural framework for the reporting process and the Population, Intervention, Comparison, Outcomes, and Context framework defined the scope of the review and focused on the research question. Six databases were accessed for the search, and 1,846 publications between 2001 and 2015 were retrieved.

RESULTS

A total of 48 articles from 9 countries met the inclusion criteria. All articles presented discussions that fundamentally included at least one principle of design and with some including all principles. The most prevailing principle discussed, found in 59% of all the articles was the need for familiarity for residents in the environmental design of facilities.

CONCLUSIONS

The review found that the eight principles of design, when applied with cultural sensitivity in countries in East and Southeast Asia can identify gaps in knowledge of the design for dementia enabling environments and suggest areas for improvement. An assessment tool based on the principles of design will be able to provide a guide for stakeholders in the design, development, or modification of nursing home environments.

An Ecological Framework to Support Small-Scale Shared Housing for Persons with Neurocognitive Disorders of the Alzheimer's and Related Types: A Literature Review

BACKGROUND

Small scale shared housing arrangements (SHAs) is a deinstitutionalized model of care designed to resemble a typical home of <10 people and are increasingly available for persons with neurocognitive disorders of the Alzheimer's and related types (NCD). However, there is little aggregate evidence of their effect on persons with NCD thus, a literature review was performed.

METHODS

Database searches were conducted across CINAHL Complete, OTseeker, PubMed, Ovid, Academic One File, ProQuest Nursing and Allied Health, the World Wide Web and Google Scholar using the several key words that included neurocognitive disorders, Alzheimer's, dementia, quality of life, well-being, occupational performance, activities of daily living, small scale shared housing, sheltered housing and group homes. Bibliographic references from final articles were also examined. Selection criteria involved three steps: screening perspective articles by title and abstract, assessing full text for eligibility and finally, reviewing full-texts.

RESULTS

16 studies were selected for final review where most found the association of SHAs with various occupational performance indicators unique to the NCD population better than or equal to controls (traditional models of long term care). A small minority of studies had mixed or inconclusive results. No study found SHAs necessarily worse than controls.

CONCLUSION

The SHA model has many benefits for person's with NCD and may be especially advantageous for those in the early stages of the disease process. The occupational therapy profession should continue to raise awareness of SHAs and consider ecological theory as a valid basis for their expansion.
