Video calls for reducing social isolation and loneliness in older people: a rapid review (Review)

NOONE Chris, et al
2020

A rapid review to assess the effectiveness of video calls for reducing social isolation and loneliness in older adults. The review also sought to address the effectiveness of video calls on reducing symptoms of depression and improving quality of life. Selection criteria: Randomised controlled trials (RCTs) and quasi‐RCTs (including cluster designs) were eligible for inclusion. Main results: Three cluster quasi-randomised trials, which together included 201 participants were included in this review. The included studies compared video call interventions to usual care in nursing homes. None of these studies were conducted during the COVID-19 pandemic. Each study measured loneliness using the UCLA Loneliness Scale. The evidence was very uncertain and suggests that video calls may result in little to no difference in scores on the Geriatric Depression Scale compared to usual care at three months' follow-up. Conclusion: Based on this review there is currently very uncertain evidence on the effectiveness of video call interventions to reduce loneliness in older adults. The review did not include any studies that reported evidence of the effectiveness of video call interventions to address social isolation in older adults. The evidence regarding the effectiveness of video calls for outcomes of symptoms of depression was very uncertain. Future research in this area needs to use more rigorous methods and more diverse and representative participants.

Effectiveness of multifactorial interventions in preventing falls among older adults in the community: a systematic review and meta-analysis.

LEE Seon Heui, YU Soyoung
2020

Background: Falls often cause unexpected injuries that older adults find difficult to recover from (e.g., hip and other major fractures, intracranial bleeding); therefore, fall prevention and interventions are of particular significance. Objectives: This study aimed to examine the effectiveness of multifactorial fall prevention interventions among community-dwelling older adults and compare subgroups that differed in terms of their degree of fall risk and the intensity and components of interventions. Methods: An exhaustive systematic literature search was undertaken using the following databases: Ovid-Medline, Ovid-Embase, and the Cochrane Central Register of Controlled Trials (Central). Two investigators independently extracted data and assessed the quality of the studies by examining the risk of bias. This study conducted a meta-analysis of randomized controlled trials that had been published up to March 31st, 2019, using Review Manager. Results: Of 1,328 studies, 45 articles were relevant to this study. In total, 29 studies included participants in the high-risk group, 3 in the frail group, and 13 in the healthy older adult group. Additionally, 28 and 17 studies used active and referral multifactorial interventions, respectively. Multifactorial interventions included the following components: exercise, education, environmental modification, medication, mobility aids, and vision and psychological management. Multifactorial interventions significantly reduced fall rates in the high-risk (risk ratio 0.66; 95% confidence interval 0.52–0.84) and healthy groups (risk ratio 0.72; 95% confidence interval 0.58–0.89), when compared to the control group. Active multifactorial interventions (risk ratio 0.64; 95% confidence interval 0.51–0.80) and those featuring exercise (risk ratio 0.66; 95% confidence interval 0.54–0.80) and environmental modification also showed significantly reduced fall rates (risk ratio 0.65; 95% confidence interval 0.54–0.79) compared to usual care. Multifactorial interventions had a significantly lower number of people who experienced falls during the study period compared to usual care in the healthy group (risk ratio 0.77; 95% confidence interval 0.62–0.95). Active multifactorial interventions (risk ratio 0.73; 95% confidence interval 0.60–0.89) and those featuring exercise (risk ratio 0.79; 95% confidence interval 0.66–0.95) and environmental modification (risk ratio 0.80; 95% confidence interval 0.68–0.95) had a significantly lower number of people who experienced falls compared to those receiving usual care. Conclusions: Active multifactorial interventions had positive effects on fall rates and the number of people experiencing falls. Thus, healthcare workers, including nurses, should be involved in planning fall prevention programs so that older adults can be provided with optimal care; multifactorial interventions that include exercise and environmental modification are particularly effective in reducing falls.

Interventions to prevent or delay long-term nursing home placement for adults with impairments: a systematic review of reviews

DUAN-PORTER Wei, et al
2020

Background: With continued growth in the older adult population, US federal and state costs for long-term care services are projected to increase. Recent policy changes have shifted funding to home and community-based services (HCBS), but it remains unclear whether HCBS can prevent or delay long-term nursing home placement (NHP). Methods: This study searched MEDLINE (OVID), Sociological Abstracts, PsycINFO, CINAHL, and Embase (from inception through September 2018); and Cochrane Database of Systematic Reviews, Joanna Briggs Institute Database, AHRQ Evidence-based Practice Center, and VA Evidence Synthesis Program reports (from inception through November 2018) for English-language systematic reviews. This study also sought expert referrals. Eligible reviews addressed HCBS for community-dwelling adults with, or at risk of developing, physical and/or cognitive impairments. Two individuals rated quality (using modified AMSTAR 2) and abstracted review characteristics, including definition of NHP and interventions. From a prioritized subset of the highest-quality and most recent reviews, this study abstracted intervention effects and strength of evidence (as reported by review authors). Results: Of 47 eligible reviews, most focused on caregiver support (n = 10), respite care and adult day programs (n = 9), case management (n = 8), and preventive home visits (n = 6). Among 20 prioritized reviews, 12 exclusively included randomized controlled trials, while the rest also included observational studies. Prioritized reviews found no overall benefit or inconsistent effects for caregiver support (n = 2), respite care and adult day programs (n = 3), case management (n = 4), and preventive home visits (n = 2). For caregiver support, case management, and preventive home visits, some reviews highlighted that a few studies of higher-intensity models reduced NHP. Reviews on other interventions (n = 9) generally found a lack of evidence examining NHP. Discussion: Evidence indicated no benefit or inconsistent effects of HCBS in preventing or delaying NHP. Demonstration of substantial impacts on NHP may require longer-term studies of higher-intensity interventions that can be adapted for a variety of settings.

Community exchange and time currencies: a systematic and in-depth thematic review of impact on public health outcomes

LEE C, et al
2020

Objectives: Austerity in government funding, and public service reform, has heightened expectations on UK communities to develop activities and resources supportive of population health and become part of a transformed place-based system of community health and social care. As non-monetary place-based approaches, Community Exchange/Time Currencies could improve social contact and cohesion, and help mobilise families, neighbourhoods, communities and their assets in beneficial ways for health. Despite this interest, the evidence base for health outcomes resulting from such initiatives is underdeveloped. Study design: A systematic review. Methods: A literature review was conducted to identify evidence gaps and advance understanding of the potential of Community Exchange System. Studies were quality assessed, and evidence was synthesised on ‘typology’, population targeted and health-related and wider community outcomes. Results: The overall study quality was low, with few using objective measures of impact on health or well-being, and none reporting costs. Many drew on qualitative accounts of impact on health, well-being and broader community outcomes. Although many studies lacked methodological rigour, there was consistent evidence of positive impacts on key indicators of health and social capital, and the data have potential to inform theory. Conclusions: Methodologies for capturing impacts are often insufficiently robust to inform policy requirements and economic assessment, and there remains a need for objective, systematic evaluation of Community Exchange and Time Currency systems. There is also a strong argument for deeper investigation of ‘programme theories’ underpinning these activities, to better understand what needs to be in place to trigger their potential for generating positive health and well-being outcomes.

The effectiveness of community-based social innovations for healthy ageing in middle- and high-income countries: a systematic review

GHIGA Ioana, et al
2020

Objectives: Community-based social innovations (CBSIs) are one type of intervention that may help to address the complex needs of ageing populations globally. The aim of this research was to assess evidence for the effectiveness and cost-effectiveness of CBSIs involving in such contexts. Methods: This study conducted a systematic review of CBSIs for healthy ageing in middle- and high-income countries, including any CBSI that aimed to empower people aged 50 and over by motivating them to take initiative for their own health and wellbeing. The protocol was registered with Prospero (CRD 42016051622). A comprehensive search was conducted in 15 academic databases and advanced search in Google. This study included published studies from 2000 onwards in any language. Exploratory meta-analysis was conducted for quantitative studies reporting similar outcomes, and qualitative studies were analysed using thematic analysis. Narrative synthesis was conducted. Searches yielded 13,262 unique hits, from which 44 papers met the inclusion criteria. Results: Most studies reported interventions having positive impacts on participants, such as reduced depression, though the majority of studies were classified as being at medium or high risk of bias. There was no evidence on costs or cost-effectiveness and very little reporting of outcomes at an organization or system level. CBSIs have the potential for positive impacts, but with nearly half of studies coming from high-income urban settings (particularly the United Kingdom and the United States of America), there is a lack of generalizability of these findings. Conclusions: This research highlights the need to improve reporting of CBSIs as complex interventions, and for improved conceptualization of these interventions to inform research and practice.

Interventions for preventing falls in older people living in the community (review)

GILLESPIE Lesley D., et al
2012

Background: Approximately 30 per cent of people over 65 years of age living in the community fall each year. This is an update of a Cochrane review first published in 2009.Objective: To assess the effects of interventions designed to reduce the incidence of falls in older people living in the community. Search methods: this review searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (February 2012), CENTRAL (The Cochrane Library2012, Issue 3), MEDLINE (1946 to March 2012), EMBASE (1947 to March 2012), CINAHL (1982 to February 2012), and online trial registers. Selection criteria: Randomised trials of interventions to reduce falls in community-dwelling older people. Main results: this review included 159 trials with 79,193 participants. Most trials compared a fall prevention intervention with no intervention or an intervention not expected to reduce falls. The most common interventions tested were exercise as a single intervention (59 trials) and multifactorial programmes (40 trials). Findings: Group and home‐based exercise programmes, usually containing some balance and strength training exercises, effectively reduced falls, as did Tai Chi. Overall, exercise programmes aimed at reducing falls appear to reduce fractures. Multifactorial interventions assess an individual's risk of falling, and then carry out treatment or arrange referrals to reduce the identified risks. Overall, current evidence shows that this type of intervention reduces the number of falls in older people living in the community but not the number of people falling during follow‐up. These are complex interventions, and their effectiveness may be dependent on factors yet to be determined. Interventions to improve home safety appear to be effective, especially in people at higher risk of falling and when carried out by occupational therapists. An anti‐slip shoe device worn in icy conditions can also reduce falls. Taking vitamin D supplements does not appear to reduce falls in most community‐dwelling older people, but may do so in those who have lower vitamin D levels in the blood before treatment. Some medications increase the risk of falling. Three trials in this review failed to reduce the number of falls by reviewing and adjusting medications. A fourth trial involving family physicians and their patients in medication review was effective in reducing falls. Gradual withdrawal of a particular type of drug for improving sleep, reducing anxiety, and treating depression (psychotropic medication) has been shown to reduce falls. Cataract surgery reduces falls in women having the operation on the first affected eye. Insertion of a pacemaker can reduce falls in people with frequent falls associated with carotid sinus hypersensitivity, a condition which causes sudden changes in heart rate and blood pressure. In people with disabling foot pain, the addition of footwear assessment, customised insoles, and foot and ankle exercises to regular podiatry reduced the number of falls but not the number of people falling. The evidence relating to the provision of educational materials alone for preventing falls is inconclusive.

Nostalgia as a psychological resource for people with dementia: a systematic review and meta-analysis of evidence of effectiveness from experimental studies

ISMAIL Sanda Umar, et al
2020

Objective: This review systematically examines evidence relating to the effect of nostalgia on psychological well-being through a meta-analysis of measures of social connectedness, self-esteem, meaning in life, self-continuity, optimism and positive and negative affect. Rationale: If nostalgia is to be used as a clinical intervention to boost well-being in dementia by reducing threat, then it is important to assess its therapeutic potential. Results: Searches carried out in July 2014 and updated in February 2018 identified 47 eligible experimental studies comparing nostalgic reminiscence and non-nostalgic reminiscence to be included in the meta-analysis. Nostalgic reminiscence had moderate effects on positive affect (0.51 (0.37, 0.65), p= 0.001), social connectedness (0.72 (0.57, 0.87), p= 0.001), self-esteem (0.50 (0.30, 0.70), p= 0.001), meaning in life (0.77 (0.47, 1.08), p= 0.001) and optimism (0.38 (0.28, 0.47), p= 0.001) and a large effect on self-continuity (0.81 (0.55, 1.07), p= 0.001). There was, however, no difference between the effect of nostalgic reminiscence and non-nostalgic reminiscence for negative affect (−0.06 (−0.20, 0.09), p= 0.443). Conclusion: This systematic review and meta-analysis provides an overview of the evidence base for nostalgia. This is an important stage in developing nostalgia as a clinical intervention for people with dementia which might be achieved, for instance, by adapting current reminiscence and life review techniques. This meta-analysis will therefore also serve as a valuable reference point for the continued exploration of nostalgia as an intervention.

What approaches to social prescribing work, for whom, and in what circumstances? A realist review

HUSK Kerryn, et al
2020

The use of non‐medical referral, community referral or social prescribing interventions has been proposed as a cost‐effective alternative to help those with long‐term conditions manage their illness and improve health and well‐being. However, the evidence base for social prescribing currently lags considerably behind practice. In this paper, we explore what is known about whether different methods of social prescribing referral and supported uptake do (or do not) work. Supported by an Expert Advisory Group, we conducted a realist review in two phases. The first identified evidence specifically relating to social prescribing in order to develop programme theories in the form of ‘if‐then’ statements, articulating how social prescribing models are expected to work. In the second phase, we aimed to clarify these processes and include broader evidence to better explain the proposed mechanisms. The first phase resulted in 109 studies contributing to the synthesis, and the second phase 34. We generated 40 statements relating to organising principles of how the referral takes place (Enrolment), is accepted (Engagement), and completing an activity (Adherence). Six of these statements were prioritised using web‐based nominal group technique by our Expert Group. Studies indicate that patients are more likely to enrol if they believe the social prescription will be of benefit, the referral is presented in an acceptable way that matches their needs and expectations, and concerns elicited and addressed appropriately by the referrer. Patients are more likely to engage if the activity is both accessible and transit to the first session supported. Adherence to activity programmes can be impacted through having an activity leader who is skilled and knowledgeable or through changes in the patient's conditions or symptoms. However, the evidence base is not sufficiently developed methodologically for us to make any general inferences about effectiveness of particular models or approaches.

The effectiveness of interventions for reducing subjective and objective social isolation among people with mental health problems: a systematic review

MA Ruimin, et al
2019

Purpose: Subjective and objective social isolation are important factors contributing to both physical and mental health problems, including premature mortality and depression. This systematic review evaluated the current evidence for the effectiveness of interventions to improve subjective and/or objective social isolation for people with mental health problems. Primary outcomes of interest included loneliness, perceived social support, and objective social isolation. Methods: Three databases were searched for relevant randomised controlled trials (RCTs). Studies were included if they evaluated interventions for people with mental health problems and had objective and/or subjective social isolation (including loneliness) as their primary outcome, or as one of a number of outcomes with none identified as primary. Results: In total, 30 RCTs met the review’s inclusion criteria: 15 included subjective social isolation as an outcome and 11 included objective social isolation. The remaining four evaluated both outcomes. There was considerable variability between trials in types of intervention and participants’ characteristics. Significant results were reported in a minority of trials, but methodological limitations, such as small sample size, restricted conclusions from many studies. Conclusion: The evidence is not yet strong enough to make specific recommendations for practice. Preliminary evidence suggests that promising interventions may include cognitive modification for subjective social isolation, and interventions with mixed strategies and supported socialisation for objective social isolation. This study highlights the need for more thorough, theory-driven intervention development and for well-designed and adequately powered RCTs.

A systematic review of interventions for loneliness among older adults living in long-term care facilities

QUAN Nicolas G., et al
2019

Objectives: This study aimed to review loneliness interventions for older adults living in long-term care (LTC) facilities over the past 10 years, to categorise interventions by type, and to compare effectiveness of loneliness interventions in these settings. Methods: Systematic review followed PRISMA guidelines. Articles matching search criteria were collected from PubMed, PsycINFO, and Web of Science from 2009 to 2019. The inclusion criteria were as follows: 1) English language, 2) intervention studies with a quantitative measure that compares pre-trial to post-trial changes, 3) loneliness as a primary or secondary outcome 4) subjects age >65, and 5) subjects living in a LTC facility, such as a nursing home, assisted-living, or hospice. Results: A total of 15 intervention studies qualified for systematic review. Most of these interventions were psychological therapies and leisure/skill development interventions. Approximately, 87% of studies reported significant decreases in loneliness following intervention. Laughter therapy, horticultural therapy, and reminiscence therapy were associated with the greatest decreases in loneliness. Discussion: Results suggest that, although less common than interventions in the community, there are several effective interventions to reduce loneliness among older adults living in LTC facilities. Lack of standardised measures and high-quality studies limits comparisons between intervention types and generalizability to different populations.
