Factors related to aggressive behaviors among older adults in nursing homes of Korea: A cross-sectional survey study

Health effects of social connectedness in older adults living in congregate long-term care settings: A systematic review of quantitative and qualitative evidence

BACKGROUND

The overall impact of social connectedness on health outcomes in older adults living in nursing homes and assisted living settings is unknown. Given the unclear health impact of social connectedness for older adults in congregate long-term care settings worldwide, a comprehensive systematic review is required to evaluate the overall relationship between social connectedness and health outcomes for them.

OBJECTIVES

The purpose of this article was to synthesize the literature regarding the health impact of social connectedness among older adults living in nursing homes or assisted living settings.

METHODS

Using PRISMA guidelines, we identified eligible studies from Scopus, MEDLINE, PsycINFO, CINAHL and Cochrane databases (1990-2021). Bias and quality reporting assessment was performed using standardized criteria for cohort, cross sectional and qualitative studies. At each stage, ≥ 2 researchers conducted independent evaluations.

RESULTS

Of the 7350 articles identified, 25 cohort (follow-up range: 1 month-11 years; with two also contributing to cross sectional), 86 cross sectional, eight qualitative and two mixed methods were eligible. Despite different instruments used, many residents living in nursing homes and assisted living settings had reduced social engagement. Quantitative evidence supports a link between higher social engagement and health outcomes most studied (e.g. depression, quality of life). Few studies evaluated important health outcomes (e.g. cognitive and functional decline). Most cohort studies showed that lack of social connectedness accelerated time to death.

CONCLUSIONS

Social connectedness may be an important modifiable risk factor for adverse health outcomes for older adults living in nursing homes and assisted living facilities. Most studies were cross sectional and focused on quality of life and mental health outcomes. Longitudinal studies suggest that higher social engagement delays time to death. Evidence regarding other health outcomes important to older adults was scant and requires further longitudinal studies.

Differences in the longitudinal change of behaviours related to dementia in long-term care: a growth mixture modelling approach

BACKGROUND

There is still a need for more information about the different trajectories of responsive behaviours that people living with dementia present in long-term care homes (LTC).

OBJECTIVE

This study identified subgroups of individuals with similar trajectories of responsive behaviours related to dementia in LTC and evaluated the role of demographic variables, depressive symptomatology, social engagement, cognitive functioning, and activities of daily living (ADL) on class membership.

METHODS

Growth mixture models were run using data from the Continuing Care Reporting System.

RESULTS

Results suggest that change in responsive behaviours is best represented by seven classes of trajectories. The largest class was composed of individuals who presented the lowest frequency of behaviours upon entry in LTC that increased at a slow linear rate. The other classes were composed of individuals who presented different frequencies of behaviours upon entry in LTC and varying rates of change (e.g., individuals who presented a low frequency of behaviours upon entry in LTC that increased at a linear rate followed by a decrease in the later months, individuals who presented a high frequency of responsive behaviours upon entry in LTC and that remained stable). Cognitive functioning, social engagement, depressive symptomatology, and ADL were markers of class membership.

CONCLUSIONS

These findings can help identify individuals at increased risk of presenting a high frequency of responsive behaviours and highlight interventions that could decrease behaviours in LTC.

[Les effets de l'environnement de soins sur les comportements réactifs des personnes ayant des troubles neurocognitifs vivant en centre d'hébergement : Une revue de la portée]

Les personnes âgées atteintes de troubles neurocognitifs (démences) vivant en centre d'hébergement adoptent fréquemment des comportements réactifs qui limitent leur engagement dans des occupations. La présente étude vise à identifier des moyens d'intervention centrés sur l'engagement des personnes âgées ayant un trouble neurocognitif avec l'environnement humain et non humain en centre d'hébergement afin de diminuer leurs comportements réactifs, en particulier les comportements d'errance, d'apathie et d'agitation. Cette revue de la portée est basée sur la méthode proposée par Levac et ses collaborateurs (2010). Parmi les 21 études retenues, la plupart s'intéressent à des interventions ciblant l'environnement non humain (n=9) ou ciblant simultanément l'environnement humain et non humain (n=9). Plusieurs de ces interventions sont efficaces pour diminuer les comportements réactifs et permettent aux personnes âgées de s'engager avec leur environnement. Le support de l'environnement humain semble toutefois nécessaire à l'utilisation optimale de plusieurs interventions.

The revised index for social engagement (RISE) in long-term care facilities: reliability and validity in Japan

BACKGROUND

This study aimed to establish the validity and reliability of a revised index for social engagement (RISE) in the Japanese context.

METHODS

We analysed the data of 1377 participants over 65 years of age who had been admitted to two types of long-term care facilities (LTCF) in Japan: four health facilities for older adults and eight nursing homes. Resident level data based on the Japanese version of the interRAI assessment instrument were collected from 623 residents in the former and 754 in the latter. From these data, we calculated RISE by adding six dichotomous items on social engagement in the assessment form. Factorial validity was evaluated by exploratory factorial analysis and confirmatory factor analysis, convergent validity by the correlation between average activity time and the RISE score, and discriminant validity by the correlation between cognitive levels and the RISE scores. Lastly, we assessed internal consistency using Cronbach's alpha.

RESULTS

We identified a two-factor model in the exploratory factorial analysis with a factor loading >0.40, except for one RISE item. The confirmatory factor analysis confirmed that the two-factor model had appropriate model fits. The correlation between time involved in activities and the RISE score was r = 0.45, while the correlation between cognitive function and the RISE score was r = -0.32. The convergent and discriminant validities supported the use of Japanese LTCF. Cronbach's alpha ranged 0.70-0.72.

CONCLUSIONS

Although further revision may be needed to improve factorial validity, RISE is reliable and valid for assessing social engagement of older adults admitted to LTCF in Japan. By using the Japanese version of RISE, the positive aspects of social functioning can be appropriately assessed and provide more evidence for improving the quality of care in LTCF.

Relationship between environmental factors and responsive behaviours in long-term care homes: a secondary data analysis

OBJECTIVE

Responsive behaviours (eg, wandering, resisting care and verbal abuse) are a continuing issue for staff and individuals living in long-term care (LTC) homes. The LTC environment can influence responsive behaviours and is a factor in determining the quality of life for those living there. The ways in which the quality of the environment might influence responsive behaviours has not been investigated yet. We hypothesised that better quality environments would be associated with reduced rates of responsive behaviours. We used a tool that simultaneously encompasses human and structural elements of the environment, a novel approach in this field of research.

DESIGN

Cross-sectional study, using data collected from September 2014 to May 2015 as part of the Translating Research in Elder Care research programme.

SETTING

A representative, stratified (size, owner-operator model and health region) random sample of 76 LTC homes in British Columbia, Alberta, Manitoba.

PARTICIPANTS

13 224 individuals (67.3% females) living in participating LTC homes.

OUTCOME MEASURES

Quality of care unit work environment was assessed using the observable indicators of quality (OIQ) tool. Responsive behaviours were assessed using routinely collected Resident Assessment Instrument-Minimum Data Set V.2.0 data.

RESULTS

Adjusted regression coefficients of overall Aggressive Behaviour Scale score and interpersonal communication were 0.02 (95% CI -0.011 to 0.045), grooming 0.06 (95% CI -0.032 to 0.157), environment-basics 0.067 (95% CI 0.024 to 0.110), odour -0.066 (95% CI -0.137 to -0.004), care delivery -0.007 (95% CI -0.033 to 0.019), environment-access -0.027 (95% CI -0.062 to 0.007), environment-homelike -0.034 (95% CI -0.065 to -0.002) and total OIQ score 0.003 (95% CI -0.004 to 0.010).

CONCLUSIONS

We found small associations between the environmental quality and responsive behaviours in Western Canadian LTC homes. Higher scores on homelikeness were associated with decreased responsive behaviours. Higher scores on basic environmental quality were associated with increased responsive behaviours.

Social Connection in Long-Term Care Homes: A Scoping Review of Published Research on the Mental Health Impacts and Potential Strategies During COVID-19

Objectives

Good social connection is associated with better health and wellbeing. However, social connection has distinct considerations for people living in long-term care (LTC) homes. The objective of this scoping review was to summarize research literature linking social connection to mental health outcomes, specifically among LTC residents, as well as research to identify strategies to help build and maintain social connection in this population during COVID-19.

Design

Scoping review.

Settings and Participants

Residents of LTC homes, care homes, and nursing homes.

Methods

We searched MEDLINE(R) ALL (Ovid), CINAHL (EBSCO), PsycINFO (Ovid), Scopus, Sociological Abstracts (ProQuest), Embase and Embase Classic (Ovid), Emcare Nursing (Ovid), and AgeLine (EBSCO) for research that quantified an aspect of social connection among LTC residents; we limited searches to English-language articles published from database inception to search date (July 2019). For the current analysis, we included studies that reported (1) the association between social connection and a mental health outcome, (2) the association between a modifiable risk factor and social connection, or (3) intervention studies with social connection as an outcome. From studies in (2) and (3), we identified strategies that could be implemented and adapted by LTC residents, families and staff during COVID-19 and included the articles that informed these strategies.

Results

We included 133 studies in our review. We found 61 studies that tested the association between social connection and a mental health outcome. We highlighted 12 strategies, informed by 72 observational and intervention studies, that might help LTC residents, families, and staff build and maintain social connection for LTC residents.

Conclusions and Implications

Published research conducted among LTC residents has linked good social connection to better mental health outcomes. Observational and intervention studies provide some evidence on approaches to address social connection in this population. Although further research is needed, it does not obviate the need to act given the sudden and severe impact of COVID-19 on social connection in LTC residents.
