Pragmatic multicentre stepped-wedge cluster randomised trial to investigate the effectiveness of community-based falls prevention programme for older adults with falls risk in Singapore: a protocol paper.

INTRODUCTION: Falls are an important public health issue with consequences that include injuries, quality of life reduction and high healthcare costs. Studies show that falls prevention strategies are effective in reducing falls rate among community-dwelling older adults. However, the evaluation for effectiveness was usually done in a controlled setting with homogeneous population, and thus may not be generalisable to a wider population. This study aims to evaluate the impact of community falls prevention programmes with group-based strength and balance exercises, on falls risk and health outcomes for older adults with falls risk in Singapore. METHODS AND ANALYSIS: This is a pragmatic closed cohort stepped-wedge cluster randomised trial design study, which involves sequential crossover of clusters from the waitlist control condition to the intervention condition, with the sequence of crossover randomly determined. The intervention will be sequentially rolled out to 12 clusters (a minimum of 5 participants/cluster), over 6 time periods with 8-week intervals in Central and North regions of Singapore. The primary analysis will be conducted under the intention-to-treat principle. A general linear mixed model or generalised estimating equation analysis appropriate for a multilevel longitudinal study incorporating an appropriate error distribution and link function will be used. Markov model will be developed to estimate the incremental cost per quality-adjusted life years and incremental cost per fall prevented from the implementation of falls prevention strategies from a societal perspective. Conditional on there being clinically relevant differences in short-term outcomes, we will implement simulation modelling to project the long-term divergence in trajectories for outcomes and costs using the Markov model. ETHICS AND DISSEMINATION: Ethics approval has been obtained. Results will be disseminated in publications and other relevant platforms. TRIAL REGISTRATION NUMBER: NCT04788251.

Bridging the intergenerational gap: the outcomes of a student-initiated, longitudinal, inter-professional, inter-generational home visit program.

BACKGROUND: Older persons consume disproportionately more healthcare resources than younger persons. Tri-Generational HomeCare (TriGen), a service-learning program, aims to reduce hospital admission rates amongst older patients with frequent admissions. The authors evaluated the educational and patient outcomes of TriGen. METHODS: Teams consisting of healthcare undergraduates and secondary school (SS) students - performed fortnightly home visits to patients over 6 months. Self-administered scales were used to evaluate the educational outcomes in knowledge and attitudes towards the older people and nine domains of soft skills pre- and post-intervention. Patients' reported satisfaction and clinical outcomes were also assessed. RESULTS: Two hundred twenty-six healthcare undergraduates and 359 SS students participated in the program from 2015 to 2018. Response rates were 80.1 and 62.4% respectively. One hundred six patients participated in TriGen. There was a significant increase in Kogan's Attitudes towards Old People Scale (KOP) scores for healthcare undergraduates and SS students with a mean increase of 12.8 (95%CI: 9.5-16.2, p <  0.001) and 8.3 (95%CI: 6.2-10.3, p <  0.001) respectively. There was a significant increase in Palmore Facts on Aging Quiz (PFAQ) score for SS students but not for healthcare undergraduates. Most volunteers reported that TriGen was beneficial across all nine domains assessed. There was also a significant decrease in hospital admission rates (p = 0.006) and emergency department visits (p = 0.004) during the 6-month period before and after the program. Fifty-one patients answered the patient feedback survey. Of this, more than 80% reported feeling less lonely and happier. CONCLUSION: TriGen, a student-initiated, longitudinal, inter-generational service-learning program consisting of SS students and healthcare undergraduates can reduce ageism, develop soft skills, inculcate values amongst SS students and healthcare undergraduates. In addition, TriGen potentially reduces hospital admissions and emergency department visits, and loneliness amongst frequently admitted older patients.

The Role of a Multicomponent Home-Health Intervention in Reducing Caregiver Stress in Singapore: A Qualitative Study.

Purpose: The relationship between caregiving and negative health outcomes is well established in the literature. Previous studies have shown that community-based programs reduce caregiver stress. However, the mechanisms by which this happens have not been well investigated. This qualitative study examines caregivers' experiences as a part of the Aging-In-Place intervention, a home-health program in Singapore targeted at frequently hospitalized patients and their caregivers. Method: We interviewed 32 caregivers to study the underlying processes by which caregiver stress was ameliorated. Transcripts from semistructured interviews were analyzed thematically within the theoretical framework of the stress process model. Results: Primary stressors related to routine patient care were reduced through the intervention program that provided health monitoring to patients and facilitated linkages to community-based services. Increased access to advice and medical information provided by intervention staff reduced caregivers' uncertainty, a substantial secondary stressor. Caregivers who employed a foreign domestic worker (FDW) gained additional reductions in both primary and secondary stressors. Discussion: The multidimensional home-health intervention reduced both primary and secondary stressors for caregivers. FDWs constituted a resource that caregivers could rely on and the training provided to FDWs by intervention staff further reduced caregiver stress. Implications for program planning and future research are discussed.

Forging a Frailty-Ready Healthcare System to Meet Population Ageing.

The beginning of the 21st century has seen health systems worldwide struggling to deliver quality healthcare amidst challenges posed by ageing populations. The increasing prevalence of frailty with older age and accompanying complexities in physical, cognitive, social and psychological dimensions renders the present modus operandi of fragmented, facility-centric, doctor-based, and illness-centered care delivery as clearly unsustainable. In line with the public health framework for action in the World Health Organization's World Health and Ageing Report, meeting these challenges will require a systemic reform of healthcare delivery that is integrated, patient-centric, team-based, and health-centered. These reforms can be achieved through building partnerships and relationships that engage, empower, and activate patients and their support systems. To meet the challenges of population ageing, Singapore has reorganised its public healthcare into regional healthcare systems (RHSs) aimed at improving population health and the experience of care, and reducing costs. This paper will describe initiatives within the RHS frameworks of the National Health Group (NHG) and the Alexandra Health System (AHS) to forge a frailty-ready healthcare system across the spectrum, which includes the well healthy ("living well"), the well unhealthy ("living with illness"), the unwell unhealthy ("living with frailty"), and the end-of-life (EoL) ("dying well"). For instance, the AHS has adopted a community-centered population health management strategy in older housing estates such as Yishun to build a geographically-based care ecosystem to support the self-management of chronic disease through projects such as "wellness kampungs" and "share-a-pot". A joint initiative by the Lien Foundation and Khoo Teck Puat Hospital aims to launch dementia-friendly communities across the island by building a network comprising community partners, businesses, and members of the public. At the National Healthcare Group, innovative projects to address the needs of the frail elderly have been developed in the areas of: (a) admission avoidance through joint initiatives with long-term care facilities, nurse-led geriatric assessment at the emergency department and geriatric assessment clinics; (b) inpatient care, such as the Framework for Inpatient care of the Frail Elderly, orthogeriatric services, and geriatric surgical services; and (c) discharge to care, involving community transitional care teams and the development of community infrastructure for post-discharge support; and an appropriate transition to EoL care. In the area of EoL care, the National Strategy for Palliative Care has been developed to build an integrated system to: provide care for frail elderly with advance illnesses, develop advance care programmes that respect patients' choices, and equip healthcare professionals to cope with the challenges of EoL care.

The effect of later-life health promotion on functional performance and body composition.

BACKGROUND AND AIMS: Functional decline in older adults is related physiologically to both aging and lifestyle-related risk factors. The role of health promotion and lifestyle modifications in preventing functional performance decline in community-dwelling older adults has not been well established. We evaluated the effects of an education-based health promotion program on functional performance and body composition in midlife and older adults. METHODS: A prospective study of a 4-week health promotion program for community- dwelling older adults. Outcome measures of gait speed, chair rise time, grip strength, weight, body mass index (BMI) and bioelectric impedance analysis (BIA) for body fat were assessed at baseline, 6 and 12 months. RESULTS: Participants (n=117) with a mean age 62.9+/-8 years; 63.2% were women. Gait speed improved by 0.20 ms-1 (95% CI 0.14, 0.29; p<0.001) and chair rise time decreased by 0.36 s (95% CI -0.13, -0.56; p=0.001) at 12 months. There was no change in grip strength (p=0.433). There was a modest decrease in weight 0.55 kg (95% CI -0.08, -1.01; p=0.019), BMI 0.35 kgm-2 (95% CI -0.02, -0.64; p=0.033) and fat impedance 0.75% (95% CI -0.09, -1.26; p=0.021) at 12 months. Imputation to account for missing outcomes did not alter overall conclusions. CONCLUSION: A 4-week education-based health promotion in later-life is feasible and may help to improve and maintain functional performance and body composition in midlife and older adults.

Habitual walking and its correlation to better physical function: implications for prevention of physical disability in older persons.

BACKGROUND: Our objective was to determine the association between participation in habitual physical activity (including walking, shopping, and indoor and outdoor activities) and leisure-time or sports activities on physical performance and fitness in older persons. METHODS: In an observational study, 123 predominantly ethnic Chinese participants aged 50 years and older were recruited from a health promotion program. Main outcome measures were bioelectric impedance for body fat composition, peak oxygen consumption (VO(2)max), gait speed, handgrip strength, and chair rise time. RESULTS: The mean age of participants was years. Those with a higher self-reported walking level had a better VO(2)max; every 1 minute per day increase in habitual walking increases VO(2)max by 0.096 (ml/kg)/min (95% confidence interval [CI] 0.027-0.165, p=.007) and is possibly associated with a faster gait speed; (95% CI 0.000-0.005, p=.078). There is an age-related rise in body fat composition, decline in VO(2)max, and slower chair rise time. Men had a lower body fat composition, better VO(2)max, and stronger handgrip. CONCLUSIONS: Habitual walking may impart important health benefits in terms of improvement in physical performance, fitness, and its implications for the prevention of physical disability in older adults. This also reinforces the theory that low- to moderate-intensity activities may improve cardiorespiratory fitness. There is an inevitable physiological age-related decline in physical fitness.
