Background: The main focus of rehabilitation following hip fracture is to regain mobility.
Objectives: To estimate the progression of real-world mobility the first year after hip fracture using digital mobility outcomes.
Design: An exploratory, prospective cohort study with pooled data from four previously conducted clinical trials.
Setting and subjects: We combined data from the Trondheim Hip Fracture Trial and Eva-Hip Trial in Trondheim, Norway, and the PROFinD 1 and PROFinD 2 trials in Stuttgart and Heidelberg, Germany, resulting in a sample of 717 hip fracture patients aged ≥65 years.
Methods: Each of the trials assessed mobility using body-fixed sensors (activPAL) at three time points, collectively providing observations across the entire first year post-surgery. The following 24-h DMOs were calculated: total walking duration (minutes), maximum number of steps within a walking bout, and number of sit-to-stand-to-walk transfers. Continuous 1-year progression of the median, the 25th percentile, and the 75th percentile were estimated using quantile regression models with splines.
Results: The dataset contained 5909 observation days. The median daily total walking duration increased until 36 weeks post-surgery reaching 40 min; daily maximum number of steps within a walking bout increased during the first eight weeks and then stabilized at less than 100 steps; daily sit-to-stand-to-walk transfers reached a plateau after 6 weeks with less than 40 transfers.
Conclusions: The three DMOs progressed differently and attained plateau levels at varying times during the first year after hip fracture, indicating that these Digital Mobility Outcomes provide complementary information about different aspects of mobility recovery.
Background: Internationally, person-centred care (PCC) is embedded in the language of regulations and mandated to be practised in residential aged care (RAC). Despite this, PCC has not been fully adopted in RAC in Australia and internationally, and concerns about the quality of care persist. Over the past 2 decades, Montessori for dementia and ageing has been introduced in RAC to support and inform a cultural change towards PCC. This study aimed to examine the intersection between the goals and approaches of Montessori and PCC in RAC.
Methods: This qualitative descriptive study reports on a secondary analysis of qualitative data from focus groups (FGs) and interviews with residents, family-members, staff, and volunteers from eight RAC homes in Victoria, Australia. Sixteen FGs and 36 interviews were conducted. A qualitative deductive approach using researcher-developed Montessori for dementia and ageing framework for data analysis was applied.
Results: Findings provide support for the intersection between PCC and Montessori with participants' descriptions of PCC aligning with many of the goals and approaches of Montessori. Participants most commonly described Montessori approaches of engagement in daily tasks with purposeful roles and promoting cognitive abilities through multi-sensory stimulation. Least frequently-described approaches included focusing on residents' strengths/abilities, maintaining function, using familiar objects, and guided repetition.
Conclusions: Findings have important implications for practice to use Montessori as a vehicle that supports and upskills the workforce to deliver care that is person-centred. Future research must examine the resources required to support the implementation and sustainability of Montessori as a vehicle for PCC.
Background: It is unclear whether social isolation and loneliness may precede frailty status or whether frailty may precipitate social isolation and loneliness. We investigated the reciprocal and temporal sequence of social isolation, loneliness, and frailty among older adults across 21 years.
Methods: We used seven waves of the Longitudinal Aging Study Amsterdam from 2302 Dutch older adults (M = 72.6 years, SD = 8.6, 52.1% female) ages 55 or older. Using random intercept cross-lagged panel models, we investigated between- and within-person associations of social isolation and loneliness with frailty. Frailty was measured using the Frailty Index. Loneliness was measured using the 11-item De Jong Gierveld Loneliness Scale. Social isolation was measured using a multi-domain 6-item scale.
Results: Social isolation and loneliness were weakly correlated across waves. At the between-person level, individuals with higher levels of frailty tended to have higher levels of social isolation but not loneliness. At the within-person level, the cross-lagged paths indicated that earlier frailty status predicted future social isolation and loneliness over time. However, prior social isolation was not associated with subsequent frailty except at time point 5 (T5). Loneliness at specific time points (T1, T4 and T6) predicted greater frailty at later time points (T2, T5 and T7). The results also supported reciprocal and contemporaneous relations between social isolation, loneliness and frailty.
Conclusions: Social isolation and loneliness are potential outcomes of frailty. Public health policies and health practitioners should prioritise interventions targeting social connection among older adults with pre-frailty or frailty.
Background: Social isolation and loneliness are associated with increased risk of adverse health outcomes at older ages. This study evaluated whether isolation and loneliness are related to inadequate intake of micronutrients in the diet.
Methods: We tested associations between social isolation and loneliness and dietary micronutrient intake 2 years later in 3713 men and women (mean age 68.26, standard deviation 7.81 years) who completed two online 24-h dietary recalls. Associations of isolation and loneliness with intake of nine minerals and vitamins that fell below national recommendations were tested using logistic regressions, adjusting for age, gender, ethnicity, education, marital status, smoking and physical activity and total energy intake.
Results: The prevalence of low dietary intake varied markedly across micronutrients. Social isolation (1-point increase in a score ranging 0-5) was associated with increased odds (adjusted for covariates) of low intake of magnesium [odds ratio (OR) 1.153, 95% confidence interval (CI) 1.037-1.282, P = .009], potassium (OR 1.201, 95% CI 1.087-1.327, P < .001), vitamin B6 (OR 1.263, 95% CI 1.110-1.438, P < .001), folate (OR 1.211, 95% CI 1.093-1.341, P < .001) and vitamin C (OR 1.238, 95% CI 1.098-1.394, P < .001). These associations remained unchanged when food insecurity and impaired activities of daily living were taken into account. By contrast, loneliness was not related to the inadequate intake of any micronutrient.
Conclusions: Low intake of micronutrients increases risk of age-related health problems. Attention to the dietary quality of older people with limited social contacts and little involvement in community activities might enhance health outcomes.
Objectives: We assessed the effects of different exercise modalities and doses on depression levels in older adults.
Methods: Systematic searches of the PubMed, Web of Science, Embase, PsycINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus databases were conducted from the start of database construction until December 2023. Studies were included if they were randomised controlled trials (RCTs) of exercise interventions in older adults. Pairwise, network and dose-network meta-analyses were conducted using random-effects models for the outcome of depression in older adults.
Results: A total of 80 RCTs with 5536 participants were included in this study. Network meta-analyses showed that resistance exercise [standardized mean difference (SMD) = - 0.68, 95% confidence interval (CI): - 0.90, - 0.46] and mind-body exercise (MBE; SMD = - 0.54, 95% CI: - 0.72, - 0.37) were the most effective forms of exercise for improving depression in older adults, followed by aerobic exercise (SMD = - 0.31, 95% CI: - 0.50, - 0.13) and mixed exercise (SMD = - 0.23, 95% CI: - 44, - 0.01). In addition, a U-shaped dose-response relationship was found between overall exercise dose and depression levels in older adults, and a significant response was seen after 390 metabolic equivalent (MET)-min/week.
Conclusions: Our study determined the effectiveness of different exercises in improving levels of older adults and found that resistance exercise and MBE were more effective adjunctive treatments. By providing the most effective treatments, older adults can reap the benefits of improving depression in older adults at doses lower than the World Health Organization guidelines.
Existing models for the safe, timely and effective delivery of health and social care are challenged by an ageing population. Services and care pathways are often optimised for single-disease management, while many older people are presenting with multiple long-term conditions and frailty. Systems engineering describes a holistic, interdisciplinary approach to change that is focused on people, system understanding, design and risk management. These principles are the basis of many established quality improvement (QI) tools in health and social care, but implementation has often been limited to single services or condition areas. Newer engineering techniques may help reshape more complex systems. Systems thinking is an essential component of this mindset to understand the underlying relationships and characteristics of a working system. It promotes the use of tools that map, measure and interrogate the dynamics of complex systems. In this New Horizons piece, we describe the evolution of systems approaches while noting the challenges of small-scale QI efforts that fail to address whole-system problems. The opportunities for novel soft-systems approaches are described, along with a recent update to the Systems Engineering Initiative for Patient Safety model, which includes human-centred design. Systems modelling and simulation techniques harness routine data to understand the functioning of complex health and social care systems. These tools could support better-informed system change by allowing comparison of simulated approaches before implementation, but better effectiveness evidence is required. Modern systems engineering and systems thinking techniques have potential to inform the redesign of services appropriate for the complex needs of older people.
Background: Exercise referral schemes (ERS) are an effective strategy for increasing physical activity (PA) in older adults. Behavioural self-management strategies (SMS) may augment the maintenance of PA and associated benefits in this population, resulting in preservation of the functional capacity and prevention of disability over the long-term.
Aim: The primary aim was to investigate the long-term (22-months) effects of ERS enhanced with SMS on functional capacity assessed by the Short Physical Performance Battery (SPPB) compared to ERS (primary comparison) and a control condition (CTRL).Secondarily, between-group effects after 4 and 16 months on the SPPB and self-reported disability outcomes were investigated.
Methods: 1360 physically inactive community-dwelling older adults ≥65 years from four European countries were randomized into (i) 16 weeks ERS enhanced with SMS (ERS-SMS), (ii) ERS alone and (iii) CTRL. In addition to SPPB, self-reported function and disability were assessed by the short-form late life function and disability index and with a six-item activity of daily living questionnaire.
Results: No long-term effects were found for the SPPB-score in ERS-SMS vs ERS (0.21 point, 95% CI [-0.04, 0.46]). Significant group × time effects were observed for the SPPB-score after 4 months in favour of ERS-SMS over CTRL (0.51 point, 95% CI [0.29, 0.73]) and ERS (0.46 point, 95% CI [0.24, 0.68]).
Conclusion: The study did demonstrate differences, in favour of ERS + SMS, but on SPPB these were small, and not sustained over time. The additional effect of SMS was inconsistent and uncertain.
Background: Tube feeding is discouraged among older adults with advanced dementia; nevertheless, caregivers often find feeding decisions challenging to navigate.
Aim: This study aims to gain a comprehensive understanding of tube feeding among community-dwelling older adults with advanced dementia in Singapore and its relationship to older adult quality of life (QoL) and caregiver psychological distress.
Methods: We use a convergent mixed-methods design, synthesising analysis of qualitative caregiver interviews (n = 25) and two-year prospective, longitudinal cohort survey data (n = 215, 1018 observations).
Results: Findings from the qualitative interviews revealed caregivers' expectations of reduced QoL for older adults with feeding tubes and their own distress related to making feeding decisions and fears prompting plans to tube-feed. Sixteen percent of community-dwelling older adults with advanced dementia relied on feeding tubes during the two-year study period. Adjusting for potential confounding and using instrumental variables estimation, tube feeding was associated with reduced older adult QoL (P < .05) and increased caregiver anxiety and depression (P < .10).
Conclusion: Consistent with expert guidelines, we found that tube feeding was associated with significantly reduced QOL among older adults living with dementia and increased distress among caregivers relative to those of older adults without feeding tubes. Despite caregivers' recognition of reduced QOL associated with older adult use of feeding tubes, many expressed angst related to feeding choices. Our findings suggest the need for decision tools to support caregivers in making informed decisions concordant with their values.
Background: The aim of this study was to develop and validate a functional ability index (FAI) that incorporates aspects of intrinsic capacity and environmental factors of older individuals based on the World Health Organization framework of healthy ageing.
Methods: Data of 7016 participants ≥60 years participating in the baseline survey of China Health and Retirement Longitudinal Study was used for the development and internal validation of the FAI. External validation was performed in a separate cohort of 1295 older individuals aged ≥60 years. Functional independency was considered the primary outcome and additional proxies of healthy ageing were considered as secondary outcomes. Cluster dendrogram was used to identify the distinct hierarchical clusters of all included variables for inclusion in the FAI. Backward elimination logistic regression model was implemented to identify the most significant variables associated with independency to be included in the FAI.
Results: The FAI score ranged from 0 to 19 and individuals having FAI ≥ 12 were more likely to be independent and at lower risk of negative outcomes. For each unit increase in the FAI the risk of having independency increased by 30%-58% cross-sectionally in the two cohorts, whilst the 2-year risk of independency increased by 20%. The FAI demonstrated a C-statistic of 0.73 (95% confidence interval, 0.72 and 0.75) for the primary outcome.
Conclusions: The FAI we developed effectively measured the functional ability status of community dwelling older individuals. FAI could serve as a tool for evaluating older individual's functional ability in routine health assessment.
