Frailty is a well known and accepted term to clinicians working with older people. The study aim was to determine whether an intervention could reduce frailty and improve mobility.

Background: Frailty is a term commonly used to describe the condition of an older person who has chronic health problems, has lost functional abilities and is likely to deteriorate further. However, despite its common use, only a small number of studies have attempted to define the syndrome of frailty and measure its prevalence. The criteria Fried and colleagues used to define the frailty syndrome will be used in this study (i.e. weight loss, fatigue, decreased grip strength, slow gait speed, and low physical activity). Previous studies have shown that clinical outcomes for frail older people can be improved using multi-factorial interventions such as comprehensive geriatric assessment, and single interventions such as exercise programs or nutritional supplementation, but no interventions have been developed to specifically reverse the syndrome of frailty. We have developed a multidisciplinary intervention that specifically targets frailty as defined by Fried et al. We aim to establish the effects of this intervention on frailty, mobility, hospitalisation and institutionalisation in frail older people. Methods and Design: A single centre randomised controlled trial comparing a multidisciplinary intervention with usual care. The intervention will target identified characteristics of frailty, functional limitations, nutritional status, falls risk, psychological issues and management of chronic health conditions. Two hundred and thirty people aged 70 and over who meet the Fried definition of frailty will be recruited from clients of the aged care service of a metropolitan hospital. Participants will be followed for a 12-month period. Discussion: This research is an important step in the examination of specifically targeted frailty interventions. This project will assess whether an intervention specifically targeting frailty can be implemented, and whether it is effective when compared to usual care. If successful, the study will establish a new approach to the treatment of older people at risk of further functional decline and institutionalisation. The strategies to be examined are readily transferable to routine clinical practice and are applicable broadly in the setting of aged care health services. Trial Registration: Australian New Zealand Clinical Trails Registry: ACTRN12608000250336.

Frailty is a common syndrome that is associated with vulnerability to poor health outcomes. Frail older people have increased risk of morbidity, institutionalization and death, resulting in burden to individuals, their families, health care services and society. Assessment and treatment of the frail individual provide many challenges to clinicians working with older people. Despite frailty being increasingly recognized in the literature, there is a paucity of direct evidence to guide interventions to reduce frailty. In this paper we review methods for identification of frailty in the clinical setting, propose a model for assessment of the frail older person and summarize the current best evidence for treating the frail older person. We provide an evidence-based framework that can be used to guide the diagnosis, assessment and treatment of frail older people.

Background: frail older people have a high risk of falling. Objective: assess the effect of a frailty intervention on risk factors for falls and fall rates in frail older people. Design: randomised controlled trial. Participants: 241 community-dwelling people aged 70+ without severe cognitive impairment who met the Cardiovascular Health Study frailty definition. Intervention: multifactorial, interdisciplinary intervention targeting frailty characteristics with an individualised home exercise programme prescribed in 10 home visits from a physiotherapist and interdisciplinary management of medical, psychological and social problems. Measurements: risk factors for falls were measured using the Physiological Profile Assessment (PPA) and mobility measures at 12 months by a blinded assessor. Falls were monitored with calendars. Results: participants had a mean (SD) age of 83.3 (5.9) years, 68% were women and 216 (90%) completed the study. After 12 months the intervention group had significantly better performance than the control group, after controlling for baseline values, in the PPA components of quadriceps strength (between-group difference 1.84 kg, 95% CI 0.17–3.51, P = 0.03) and body sway (−90.63 mm, 95% CI −168.6 to −12.6, P = 0.02), short physical performance battery (1.58, 95% CI 1.02–2.14, P ≤ 0.001) and 4 m walk (0.06 m/s 95% CI 0.01–0.10, P = 0.02) with a trend toward a better total PPA score (−0.40, 95% CI −0.83–0.04, P = 0.07) but no difference in fall rates (incidence rate ratio 1.12, 95% CI 0.78–1.63, P = 0.53). Conclusion: the intervention improved performance on risk factors for falls but did not reduce the rate of falls. Trial registration: ACTRN12608000250336.

Social prescribing, also known as “community referral”, is a means of referring individuals living in the community to existing local non-clinical health, welfare, and social support services. International evidence demonstrates that social prescribing improves biopsychosocial quality of life, and burden on health services. Australia’s first social prescribing pilot program for individuals with mental illness (mood and psychotic spectrum disorders) was implemented in Sydney in 2016/2017; this study evaluates that program. Participants included 13 adults who were assessed at baseline and six-month follow-up. Outcomes included self-perceived quality of life, welfare needs, health status, loneliness, social participation, and economic participation. Results indicate significant improvements in quality of life and health status. This pilot program demonstrates that social prescribing may improve participant outcomes. It fits well within Australian health policy and funding models which focus on bolstering community care, and may be scalable, particularly in geographically isolated communities.
