Review focus: This systematic review looked at whether social participation activities improve quality of life for older people living in residential aged care. It included peer-reviewed English-language intervention studies published between 2015 and 2025. The studies involved residents aged 65 years and over and measured quality of life.
Review findings: Ten studies met the inclusion criteria. Together, they included 2325 participants from 147 residential aged care homes. Quality of life improved in studies using virtual reality tourism, resistance training, Sinaki exercises, Tai Chi and two multicomponent person-centred care programmes involving pain management, communication, activity organisation and medication review. The evidence was limited and fragmented because the interventions varied widely and the review did not include a meta-analysis, so the findings should be interpreted with caution.
Workforce relevance: Aged care workers can help residents take part in meaningful social activities. This may include group activities, person-centred support and chances to spend time with other people. Some interventions also used staff training and coordinated care approaches, including better communication, activity planning, pain management and medication review. Social participation may help improve residents’ quality of life, but the best approach will depend on the resident group, the type of activity and the care setting.

Review focus: This systematic review and meta-analysis looked at whether PARO, a robotic seal designed to provide social interaction, improves behavioural and psychological outcomes for people with dementia in Australian healthcare settings. The meta-analysis focused on Australian randomised controlled trials that compared PARO with standard care or other control conditions.
Review findings: The review included 45 studies. 6 Australian randomised controlled trials, with 1,444 participants, were included in the meta-analysis. PARO reduced agitation and anxiety compared with control conditions. It did not significantly reduce depression. The evidence is still preliminary because only a small number of studies contributed to each outcome, the interventions differed and long-term effects remain uncertain.
Workforce relevance: Staff need training to use socially assistive robots as part of everyday care routines. Services also need to consider the cost of buying, maintaining and managing the robots. Some staff may worry that robots could replace human contact, disrupt work routines or may not save money over time. Implementation is more likely to work when staff receive education, services have clear guidance and leaders assess the costs and benefits. PARO should support human care, not replace it.

Review focus: This meta-synthesis explored how relatives experience their role and identity when a family member lives in long-term care. It also looked at nursing staff perceptions of relatives.
Review findings: The qualitative meta-synthesis included 59 qualitative or mixed-methods studies from 14 countries. It examined relationships between relatives, residents and staff. The review found four connected themes: mixed emotions, changing family roles, relationships with staff and shared responsibility for care. Relatives could feel valued when staff recognised their contribution. They could feel ignored or powerless when staff left them out of discussions or treated them as outsiders. The review describes this as an ongoing process, where relatives keep adjusting their involvement based on their emotions, relationships with staff, residents’ needs and the expectations of the care home.
Workforce relevance: Staff need to see relatives as people with their own needs and identities, not only as visitors, advocates or carers. Care services can support better relationships by having a clear contact person, giving staff and relatives chances to talk, using clear ways to manage conflict and regularly asking relatives how they want to be involved in care. Flexible approaches may reduce tension, build stronger partnerships with staff and support more person-centred care.
Review focus: This systematic review looked at how Communities of Practice have been developed, run and evaluated in long-term care. It also examined barriers and enablers. The review focused on Communities of Practice that help aged care workers use evidence, best practice or quality improvement in their work.
Review findings: The review included 15 papers about 8 Communities of Practice programs. Seven programs involved more than one staff group and seven used a definition or framework to guide development. None reported formal co-design. Communities of Practice supported learning, peer support, collaboration, skill building and putting learning into practice. However, much of the evidence came from participants’ own reports. Few full evaluations were available, so it is hard to know which approaches work best or whether benefits last.
Workforce relevance: Communities of Practice can give aged care workers peer support, shared learning and professional development. This may be useful in a sector where mentoring and staff support can be limited. Participation worked better when managers supported it, staff had dedicated time and permission to take part and trusting relationships were built. Staffing gaps, turnover, shift work and competing care demands made participation harder. Leaders have an important role in creating the time, resources and support workers need to take part and use what they learn.
Review focus: This scoping review looked at the costs and cost-effectiveness of palliative care in residential aged care homes. It included studies that reported economic outcomes for palliative, hospice or end-of-life care. The review aimed to identify gaps in the evidence that could guide decisions about how resources are used.
Review findings: The review included 15 studies. Three looked at the cost of delivering care, 10 looked at healthcare system costs and two assessed cost-effectiveness. Delivering palliative care added care costs. Six of the 10 healthcare cost studies reported savings, mainly through fewer hospital admissions, shorter hospital stays or fewer transfers. One study reported higher costs and three had mixed findings. The economic evidence was limited and varied between studies, so it is hard to make firm conclusions about value for money.
Workforce relevance: Palliative care in residential aged care may be provided by aged care staff, GPs, specialist multidisciplinary teams or a mix of these. Some models included staff education, training and clinical support from palliative care specialists. Leaders need to consider the resources needed to deliver palliative care, as well as possible savings from avoiding hospital care. The evidence is not strong enough to show which models offer the best value, especially for specialist palliative care.

Review focus: This systematic review assessed whether Mediterranean, Nordic, Okinawan and plant-based whole-food diets help reduce cognitive decline and dementia risk in adults aged 60 years and over. It focused on dietary patterns that may support cognitive health, rather than single nutrients or supplements.
Review findings: The review included 16 studies with older adults living in the community or long-term care. Across the studies, people who followed whole-food dietary patterns more closely tended to have better memory, executive function and other cognitive outcomes. They also had a lower risk of Alzheimer’s disease or dementia. No single diet was identified as best. The diets shared features such as more plant-rich foods, healthier fats and lower inflammation. Differences in study design and cognitive measures meant the results could not be combined in a meta-analysis. Because much of the evidence was observational, longer-term findings show links rather than clear cause and effect.
Workforce relevance: Long-term care leaders and healthcare providers may use these findings to support nutrition planning. This could include more nutrient-dense meals and less ultra-processed food. Services also need to consider whether residents can prepare food or use utensils, and whether they need nutrition education or behaviour support. The review included people living in both the community and long-term care, so the findings should not be treated as residential aged care evidence only.

Review focus: This systematic review and meta-analysis looked at whether group reminiscence therapy improves psychosocial outcomes for nursing home residents aged 60 years and over with intact cognition or mild cognitive impairment. Outcomes included depression, life satisfaction, quality of life, loneliness, self-esteem, anxiety and wellbeing.
Review findings: The review included 19 studies with 925 residents. Four were randomised controlled trials and 15 were quasi-experimental studies. Group reminiscence reduced depression and death anxiety. It also improved life satisfaction, self-esteem and happiness. It did not significantly reduce loneliness. The findings should be interpreted with caution because there were few randomised controlled trials, some outcomes varied between studies and evidence on longer-term effects was limited.
Workforce relevance: Nursing home staff and managers could use structured reminiscence activities as part of routine psychosocial care. These activities may support emotional wellbeing and social interaction. Programs varied in length and format, from 3 to 12 sessions of 30 to 120 minutes, with 5 to 15 residents in each group. Services may need to consider these differences when planning activities. Cultural context also matters when adapting reminiscence programs for different resident groups.

Review focus: This systematic review and meta-analysis looked at which antimicrobial stewardship interventions reduce inappropriate antibiotic prescribing for urinary issues in residential aged care. It focused on suspected urinary tract infections and asymptomatic bacteriuria, which means bacteria are present in urine but there are no symptoms of infection.
Review findings: The review included 20 studies. Four randomised controlled trials were included in the meta-analysis. Education combined with clinical decision tools, routine audits and feedback reduced urinary antibiotic prescribing. These interventions did not significantly increase hospitalisations. The findings should be interpreted with caution because interventions and outcome reporting varied, which limited how many studies could be combined.
Workforce relevance: Interventions often used staff and clinician education with clinical decision tools. Regular audits and personalised feedback also helped improve prescribing. Webinars and e-learning helped reduce time and scheduling barriers for workers. High staff turnover and the lack of a consistent stewardship team can make improvements hard to sustain, so aged care services may need dedicated antimicrobial stewardship leadership.

Review focus: This scoping review explored how care home residents, staff and family members view wearable devices, such as smartwatches, monitoring sensors and sensor-enabled clothing. It examined acceptability, perceived value and issues that affect implementation in care homes.
Review findings: The review included 12 studies. Most were qualitative or mixed-methods studies. Devices included activity and sleep trackers, wireless monitoring systems, incontinence sensors and other wearable technologies. Wearables were more accepted when they were familiar, passive and not stigmatising. Reported benefits included reassurance, better visibility of residents’ health information, safety and quality of life. The evidence was limited by small samples, short evaluation periods and a focus on high-income Western countries, so it may not apply to all care settings.
Workforce relevance: Wearables could reduce workload when they support routine tasks, such as continence monitoring or repositioning. They could also increase workload if staff need to charge, handle, manage or monitor devices that do not fit well into care routines. Implementation may need early training, ongoing support and visible support from colleagues and managers. Services also need to consider costs, workflow and concerns about staff surveillance. Implementation should be designed with residents, families and care staff so devices fit everyday care and protect residents’ privacy, autonomy and dignity.

Review focus: This systematic review examined what helps or hinders advance care planning in nursing homes. It focused on the organisational structures and care processes needed to support consistent advance care planning practice.
Review findings: The review included 19 studies. It identified 11 elements across two main areas. The first was organisational support, including clear roles, dedicated time and staff training. The second was standardised processes, including involving residents and families, building trust, discussing preferences, recording decisions, sharing information across teams and regularly reviewing advance care plans. The studies varied in design and reporting. None directly assessed overall implementation quality, so the review could not show which elements were most important.
Workforce relevance: Staff need clear responsibilities, protected time and training to support advance care planning conversations. This is especially important when residents live with dementia or have impaired decision-making capacity. Training alone may not be enough without practical experience and leadership support. Dedicated advance care planning facilitators, interdisciplinary teamwork and the involvement of care aides may help because care aides often know residents and families well. Leaders can support practice by providing resources, staff coverage, standardised documentation and processes for sharing and reviewing residents’ preferences.
