Efficacy and generalizability of falls prevention interventions in nursing homes: a systematic review and meta-analysis

GULKA Heidi J, et al

Objectives: To determine the efficacy of fall intervention programs in nursing homes (NHs) and the generalizability of these interventions to people living with cognitive impairment and dementia. Design: Systematic review and meta-analysis. Setting and Participants: NH residents (n = 30,057) living in NHs defined as residential facilities that provide 24-hours-a-day surveillance, personal care, and some clinical care for persons who are typically aged ≥65 years with multiple complex chronic health conditions. Methods: Meta-analysis of falls prevention interventions on number of falls, fallers, and recurrent fallers. Results: Thirty-six studies met inclusion criteria for the systematic review. Overall, fall prevention interventions reduced the number of falls [risk ratio (RR) = 0.73, 95% confidence interval (CI) = 0.60-0.88], fallers (RR = 0.80, 95% CI = 0.72-0.89), and recurrent fallers (RR = 0.70, 95% CI = 0.60-0.81). Subanalyses revealed that single interventions have a significant effect on reducing fallers (RR = 0.78, 95% CI = 0.69-0.89) and recurrent fallers (RR = 0.60, 95% CI = 0.52-0.70), whereas multiple interventions reduce fallers (RR = 0.69, 95% CI = 0.39-0.97) and multifactorial interventions reduce number of falls (RR = 0.65, 95% CI = 0.45-0.94). Conclusions and Implications: Exercise as a single intervention reduced the number of fallers and recurrent fallers by 36% and 41%, respectively, in people living in NHs. Other effective interventions included staff education and multiple and multifactorial interventions. However, more research on exercise including people with cognitive impairment and dementia is needed to improve the generalizability of these interventions to the typical NH resident.

Social identification moderates cognitive health and well-being following story- and song-based reminiscence

HASLAM Catherine, et al

Objectives: Reminiscence is a popular intervention for seniors, but, with mixed evidence supporting its efficacy, questions have been raised about the mechanisms underlying improvement. The present paper addresses this question by investigating the degree to which health effects depend on the development of a shared sense of group identification. This is examined in the context of traditional story-based reminiscence as well as novel forms of song-based reminiscence.Method: As the focus of a manualised intervention, 40 participants were randomly assigned to secular song (n = 13), religious song (n = 13), or standard story reminiscence (n = 14) groups. These were run over six weeks with cognitive performance, anxiety, and life satisfaction measured before and after the intervention. Measures of group fit were included to examine whether social identification contributed to outcomes.Results: No evidence of change emerged over time as a function of intervention form alone, but analysis of identification data revealed significant interactions with the type of reminiscence group. Specifically, initial fit with the story reminiscence group was associated with enhanced cognitive outcomes and greater life satisfaction, while fit with the religious song reminiscence group was associated with greater life satisfaction and less anxiety.Conclusion: These findings show that group identification is a key moderator through which reminiscence promotes health outcomes. Implications for theory and practice highlight an inherent limitation in randomised controlled trials insofar as they may compromise participants’ group identification.

Effect of board game activities on cognitive function improvement among older adults in adult day care centers


Stimulating leisure activities are considered as possible protective factors against dementia and cognitive decline in older adults, particularly due to the enhancement of cognitive reserve. This study tested the effectiveness of board game activities improving the cognitive function of older adults in adult day care centres. This was a quasi‐experimental study. A purposive sampling strategy was used to select 82 subjects who were aged 65 and above with intact mental functions and currently residing in adult day care centres. 41 subjects who participated in a selection of 12 board game activities were assigned to the experimental group and 41 subjects who adhered to their ordinary activities were allocated to the control group. Structured questionnaires of the board game programs were used for data collection. The board game programs showed promising effects in the cognitive function of older adults living in adult day care centres. A possible beneficial effect of board game playing on the risk of dementia could be mediated by a less cognitive decline in older adults. Board game activities may benefit the cognitive function of older adults. Incorporating board game activities into social work care may help develop long‐term care into a more diverse, unique and innovative direction.

Acceptance and use of innovative assistive technologies among people with cognitive impairment and their caregivers: a systematic review


Cognitive impairments (CI), associated with the consequences of Alzheimer’s disease and other dementias, are increasingly prevalent among older adults, leading to deterioration in self-care, mobility, and interpersonal relationships among them. Innovative Assistive Technologies (IAT) such as electronic reminders and surveillance systems are considered as increasingly important tools to facilitate independence among this population and their caregivers. The aim of this study is to synthesise knowledge on facilitators and barriers related to acceptance of and use of IAT among people with CI and their caregivers. This systematic review includes original papers with quantitative, qualitative, or mixed methods design. Relevant peer-reviewed articles published in English between 2007 and 2017 were retrieved in the following databases: CINAHL; PubMed; Inspec; and PsycINFO. The Mixed Method Appraisal Tool (MMAT) was used for quality assessment. We retrieved thirty studies, including in total 1655 participants from Europe, USA/Canada, Australia, and Asia, enrolled in their homes, care-residences, day-care centres, or Living Labs. Two-thirds of the studies tested technologies integrating home sensors and wearable devices for care and monitoring CI symptoms. Main facilitators for acceptance and adherence to IAT were familiarity with and motivation to use technologies, immediate perception of effectiveness (e.g., increase in safety perceptions), and low technical demands. Barriers identified included older age, low maturity of the IAT, little experience with technologies in general, lack of personalization, and support. More than 2/3 of the studies met 80% of the quality criteria of the MMAT. Low acceptance and use of IAT both independently and with caregivers remains a significant concern. More knowledge on facilitators and barriers to use of IAT among clients of health care and social services is crucial for the successful implementation of innovative programmes aiming to leverage innovative technologies for the independence of older people with CI.

Cognitive behavioural therapy for fear of falling and balance among older people: a systematic review and meta-analysis

LIU Tai-Wa, et al

Background: fear of falling is prevalent among older people and associated with various health outcomes. A growing number of studies have examined the effects of interventions designed to reduce the fear of falling and improve balance among older people, yet our current understanding is restricted to physiological interventions. Psychological interventions such as cognitive behavioural therapy (CBT) have not been reviewed and meta-analysed. Objective: to perform a systematic review and meta-analysis evaluating the effects of CBT on reducing fear of falling and enhancing balance in community-dwelling older people. Method: randomised controlled trials (RCTs) addressing fear of falling and balance were identified through searches of six electronic databases, concurrent registered clinical trials, forward citation and reference lists of three previous systematic reviews. Results: a total of six trials involving 1,626 participants were identified. Four studies used group-based interventions and two adopted individual intervention. Intervention period ranged from 4 to 20 weeks, and the number and duration of face-to-face contact varied. Core components of the CBT intervention included cognitive restructuring, personal goal setting and promotion of physical activities. The risk of bias was low across the included studies. Our analysis suggests that CBT interventions have significant immediate and retention effects up to 12 months on reducing fear of falling, and 6 months post-intervention effect on enhancing balance. Conclusions: CBT appears to be effective in reducing fear of falling and improving balance among older people. Future researches to investigate the use of CBT on reducing fear of falling and improving balance are warranted.
