Hospital-Based Health Professionals' Perceptions of Frailty in Older People. THE GERONTOLOGIST 2024:gnae041. [PMID: 38712983 DOI: 10.1093/geront/gnae041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Indexed: 05/08/2024] Open
Abstract
BACKGROUND AND OBJECTIVES There is a high prevalence of frailty amongst older patients in hospital settings. Frailty guidelines exist but implementation to date has been challenging. Understanding health professional attitudes, knowledge, and beliefs about frailty is critical in understanding barriers and enablers to guideline implementation and the aim of this study was to understand these in rehabilitation multidisciplinary teams in hospital settings. RESEARCH DESIGN AND METHODS Twenty-three semi-structured interviews were conducted with health professionals working in multi-disciplinary teams on geriatric and rehabilitation wards in Adelaide and Sydney, Australia. Interviews were audio recorded, transcribed, and coded by two researchers. A codebook was created and interviews re-coded and applied to the Framework Method of thematic analysis. RESULTS Three domains were developed: diagnosing frailty, communicating about frailty, and managing frailty. Within these domains, eight themes were identified: (1) diagnosing frailty has questionable benefits, (2) clinicians don't use frailty screening tools, (3) frailty can be diagnosed on appearance and history, (4) frailty has a stigma, (5) clinicians don't use the word "frail" with patients, (6) frailty isn't always reversible, (7) there is a lack of continuity of care after acute admission, and (8) the community setting lacks resources. DISCUSSION AND IMPLICATIONS Implementation of frailty guidelines will remain challenging while staff avoid using the term "frail", don't perceive benefit of using screening tools, and focus on the individual aspects of frailty rather than the syndrome holistically. Clinical champions and education about frailty identification, reversibility, management, and communication techniques may improve the implementation of frailty guidelines in hospitals.

Measuring the success of programmes of care for people living with dementia: a protocol for consensus building with consumers to develop a set of Core Outcome Measures for Improving Care (COM-IC). BMJ Open 2023; 13:e073884. [PMID: 38072498 PMCID: PMC10729031 DOI: 10.1136/bmjopen-2023-073884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Accepted: 11/19/2023] [Indexed: 12/18/2023] Open
Abstract
INTRODUCTION The Core Outcome Measures for Improving Care (COM-IC) project aims to deliver practical recommendations on the selection and implementation of a suite of core outcomes to measure the effectiveness of interventions for dementia care. METHODS AND ANALYSIS COM-IC embeds a participatory action approach to using the Alignment-Harmonisation-Results framework for measuring dementia care in Australia. Using this framework, suitable core outcome measures will be identified, analysed, implemented and audited. The methods for analysing each stage will be codesigned with stakeholders, through the conduit of a Stakeholder Reference Group including people living with dementia, formal and informal carers, aged care industry representatives, researchers, clinicians and policy actors. The codesigned evaluation methods consider two key factors: feasibility and acceptability. These considerations will be tested during a 6-month feasibility study embedded in aged care industry partner organisations. ETHICS AND DISSEMINATION COM-IC has received ethical approval from The University of Queensland (HREC 2021/HE001932). Results will be disseminated through networks established over the project, and in accordance with both the publication schedule and requests from the Stakeholder Reference Group. Full access to publications and reports will be made available through UQ eSpace (https://espace.library.uq.edu.au/), an open access repository hosted by The University of Queensland.

Implementation of a frailty intervention in the transition from hospital to home: a realist process evaluation protocol for the FORTRESS trial. BMJ Open 2023; 13:e070267. [PMID: 37295839 PMCID: PMC10277088 DOI: 10.1136/bmjopen-2022-070267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 03/30/2023] [Indexed: 06/12/2023] Open
Abstract
INTRODUCTION Frailty in Older people: Rehabilitation, Treatment, Research Examining Separate Settings (the FORTRESS study) is a multisite, hybrid type II, stepped wedge, cluster, randomised trial examining the uptake and outcomes of a frailty intervention. The intervention is based on the 2017 Asia Pacific Clinical Practice Guidelines for the Management of Frailty and begins in the acute hospital setting and transitions to the community. The success of the intervention will require individual and organisational behaviour change within a dynamic health system. This process evaluation will examine the multiple variables at play in the context and mechanism of the frailty intervention to enhance understanding of the outcomes of the FORTRESS study and how the outcomes can be translated from the trial into broader practice. METHODS AND ANALYSIS The FORTRESS intervention will recruit participants from six wards in New South Wales and South Australia, Australia. Participants of the process evaluation will include trial investigators, ward-based clinicians, FORTRESS implementation clinicians, general practitioners and FORTRESS participants. The process evaluation has been designed using realist methodology and will occur in parallel to the FORTRESS trial. A mixed-method approach will be used with qualitative and quantitative data collected from interviews, questionnaires, checklists and outcome assessments. Qualitative and quantitative data will be examined for CMOCs (Context, Mechanism, Outcome Configurations) and programme theories will be developed, tested and refined. This will facilitate development of more generalisable theories to inform translation of frailty intervention within complex healthcare systems. ETHICS AND DISSEMINATION Ethical approval for the FORTRESS trial, inclusive of the process evaluation, has been obtained from the Northern Sydney Local Health District Human Research Ethics Committees reference number 2020/ETH01057. Recruitment for the FORTRESS trial uses opt-out consent. Dissemination will be via publications, conferences and social media. TRIAL REGISTRATION NUMBER ACTRN12620000760976p (FORTRESS trial).

Characterising Australian memory clinics: current practice and service needs informing national service guidelines. BMC Geriatr 2022; 22:578. [PMID: 35836238 PMCID: PMC9281346 DOI: 10.1186/s12877-022-03253-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 06/03/2022] [Indexed: 11/22/2022] Open
Abstract
Background Memory clinics (MCs) play a key role in accurate and timely diagnoses and treatment of dementia and mild cognitive impairment. However, within Australia, there are little data available on current practices in MCs, which hinder international comparisons for best practice, harmonisation efforts and national coordination. Here, we aimed to characterise current service profiles of Australian MCs. Methods The ‘Australian Dementia Network Survey of Expert Opinion on Best Practice and the Current Clinical Landscape’ was conducted between August-September 2020 as part of a larger-scale Delphi process deployed to develop national MC guidelines. In this study, we report on the subset of questions pertaining to current practice including wait-times and post-diagnostic care. Results Responses were received from 100 health professionals representing 60 separate clinics (45 public, 11 private, and 4 university/research clinics). The majority of participants were from clinics in metropolitan areas (79%) and in general were from high socioeconomic areas. While wait-times varied, only 28.3% of clinics were able to offer an appointment within 1-2 weeks for urgent referrals, with significantly more private clinics (58.3%) compared to public clinics (19.5%) being able to do so. Wait-times were less than 8 weeks for 34.5% of non-urgent referrals. Only 20.0 and 30.9% of clinics provided cognitive interventions or post-diagnostic support respectively, with 7.3% offering home-based reablement programs, and only 12.7% offering access to group-based education. Metropolitan clinics utilised neuropsychological assessments for a broader range of cases and were more likely to offer clinical trials and access to research opportunities. Conclusions In comparison to similar countries with comprehensive government-funded public healthcare systems (i.e., United Kingdom, Ireland and Canada), wait-times for Australian MCs are long, and post-diagnostic support or evidence-based strategies targeting cognition are not common practice. The timely and important results of this study highlight a need for Australian MCs to adopt a more holistic service of multidisciplinary assessment and post-diagnostic support, as well as the need for the number of Australian MCs to be increased to match the rising number of dementia cases.

Frailty in older people: Rehabilitation Treatment Research Examining Separate Settings (FORTRESS): protocol for a hybrid type II stepped wedge, cluster, randomised trial. BMC Geriatr 2022; 22:527. [PMID: 35761212 PMCID: PMC9235164 DOI: 10.1186/s12877-022-03178-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 05/26/2022] [Indexed: 11/10/2022] Open
Abstract
Background Frailty in older people is associated with increased risk of falls, longer length of stay in hospital, increased risk of institutionalisation and death. Frailty can be measured using validated tools. Multi-component frailty interventions are recommended in clinical practice guidelines but are not routinely implemented in clinical practice. Methods The Frailty in Older people: Rehabilitation, Treatment, Research Examining Separate Settings (FORTRESS) trial is a multisite, hybrid type II, stepped wedge, cluster, randomised trial with blinded assessment and intention-to-treat analysis being conducted in Australia. The study aims to determine the effectiveness and cost-effectiveness of an embedded individualised multicomponent frailty intervention (commencing in hospital and continuing in the community) on readmissions, frailty and quality of life when compared with usual care. Frail older people admitted to study wards with no significant cognitive impairment, who are expected to return home after discharge, will be eligible to participate. Participants will receive extra sessions of physiotherapy, pharmacy, and dietetics during their admission. A Community Implementation Facilitator will coordinate implementation of the frailty management strategies and primary network liaison. The primary outcome is number of days of non-elective hospital readmissions during 12 month follow-up period. Secondary outcomes include frailty status measured using the FRAIL scale; quality of life measured using the EQ-5D-5L; and time-to-event for readmission and readmission rates. The total cost of delivering the intervention will be assessed, and cost-effectiveness analyses will be conducted. Economic evaluation will include analyses for health outcomes measured in terms of the main clinical outcomes. Implementation outcomes will be collected as part of a process evaluation. Recruitment commenced in 2020 and we are aiming to recruit 732 participants over the three-year duration of the study. Discussion This study will reveal whether intervening with frail older people to address factors contributing to frailty can reduce hospital readmissions and improve frailty status and quality of life. If the FORTRESS intervention provides a clinically significant and cost-effective result, it will demonstrate an improved approach to treating frail patients, both in hospital and when they return home.

Abstract
OBJECTIVES The Australian Ageing Semantic Differential (AASD) survey was developed to quantify medical student attitudes towards older people. The purpose of this study is to examine psychometric properties of the survey and confirm its factor structure of four composites. DESIGN A cross-sectional study. SETTING Three medical schools in three Australian states: Victoria, Western Australia and South Australia. PARTICIPANTS Third-year or fourth-year medical students (n=188, response rate=79%). OUTCOME MEASURES In the previous AASD study, exploratory factor analysis supported a four-factor model consisting of 'Instrumentality' (I), 'Personal Appeal' (PA), 'Experience' (E) and 'Sociability' (S). Congeneric one-factor confirmatory factor analysis (CFA) were used to examine model fit for factors using a new student sample (n=188).Psychometric properties of survey items and factors.Post-hoc analysis of pooled data from this study and earlier AASD study (n=509). RESULTS Indices of fit (Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), root mean square error of approximation (RMSEA), standardised root mean square residual (SRMR)) for data to the factor model were: PA adequate fit (CFI=0.94, TLI=0.89, RMSEA=0.11 and SRMR=0.05), I good fit (CFI=0.99, TLI=0.99, RMSEA=0.04 and SRMR=0.03), S good fit (CFI=0.98, TLI=0.95, RMSEA=0.06 and SRMR=0.03) and E excellent fit (CFI=1.0, TLI=1.0, RMSEA=0.00 and SRMR=0.01).The AASD was internally consistent (Cronbach's alpha=0.84), without difference in mean student scores by institution. Mean AASD score was positive for medical students outside New South Wales (73.2/114).Mean I score for all Australian students was negative, with female respondents' mean E score significantly higher than their counterparts. A positive correlation between student age and I score was noted. CONCLUSIONS The AASD is internally consistent and generalisable within Australia, with acceptable structural validity for measuring medical student attitudes towards older people within a four-factor model. Student attitudes were positive globally and within all factors except I. Female students rated older persons E more positively. Older students recorded more positive attitudes towards I of older people.

Pilot feasibility study of a home-based fall prevention exercise program (StandingTall) delivered through a tablet computer (iPad) in older people with dementia. Australas J Ageing 2019; 39:e278-e287. [PMID: 31538401 DOI: 10.1111/ajag.12717] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2019] [Revised: 07/30/2019] [Accepted: 08/01/2019] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To assess the feasibility and safety of StandingTall-an individually tailored, progressive exercise program delivered through tablet computers-in community-dwelling older people with dementia. METHODS Fifteen community-dwelling older people with dementia (mean age = 83 ± 8 years; Montreal Cognitive Assessment 16 ± 5) received StandingTall for 12 weeks with caregiver assistance. Feasibility and safety were assessed using the System Usability Scale (SUS; scores = 0-100; a priori target >65), Physical Activity Enjoyment Scale (PACES-8; scores = 8-56), adherence (exercise minutes) and adverse events. RESULTS Mean SUS scores were 68 ± 21/69 ± 15 (participants/caregivers). The mean PACES-8 score was 44 ± 8. In week 2, week 7 and week 12, mean (bias-corrected and accelerated 95% CI) exercise minutes were 37 (25-51), 49 (30-69) and 65 (28-104), respectively. In week 12, five participants exercised >115 minutes. One participant fell while exercising, without sustained injury. CONCLUSIONS StandingTall had acceptable usability, scored well on enjoyment and was feasible for participants. These results provide support for further evaluation of StandingTall in a randomised controlled trial with falls as the primary outcome.

Abstract
INTRODUCTION Delirium is a significant medical complication for hospitalised patients. Up to one-third of delirium episodes are preventable in older inpatients through non-pharmacological strategies that support essential human needs, such as physical and cognitive activity, sleep, hydration, vision and hearing. We hypothesised that a multicomponent intervention similarly may decrease delirium incidence, and/or its duration and severity, in inpatients with advanced cancer. Prior to a phase III trial, we aimed to determine if a multicomponent non-pharmacological delirium prevention intervention is feasible and acceptable for this specific inpatient group. METHODS AND ANALYSIS The study is a phase II cluster randomised wait-listed controlled trial involving inpatients with advanced cancer at four Australian palliative care inpatient units. Intervention sites will introduce delirium screening, diagnostic assessment and a multicomponent delirium prevention intervention with six domains of care: preserving natural sleep; maintaining optimal vision and hearing; optimising hydration; promoting communication, orientation and cognition; optimising mobility; and promoting family partnership. Interdisciplinary teams will tailor intervention delivery to each site and to patient need. Control sites will first introduce only delirium screening and diagnosis, later implementing the intervention, modified according to initial results. The primary outcome is adherence to the intervention during the first seven days of admission, measured for 40 consecutively admitted eligible patients. Secondary outcomes relate to fidelity and feasibility, acceptability and sustainability of the study intervention, processes and measures in this patient population, using quantitative and qualitative measures. Delirium incidence and severity will be measured to inform power calculations for a future phase III trial. ETHICS AND DISSEMINATION Ethical approval was obtained for all four sites. Trial results, qualitative substudy findings and implementation of the intervention will be submitted for publication in peer-reviewed journals, and reported at conferences, to study sites and key peak bodies.

Abstract
INTRODUCTION Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia. The Quality of Life in Alzheimer's Disease (QOL-AD) is a widely used and well-validated condition-specific instrument for assessing health-related quality of life for people living with dementia, but it does not enable the calculation of quality-adjusted life years, the basis of cost utility analysis. This study will generate a preference-based scoring algorithm for a health state classification system -the Alzheimer's Disease Five Dimensions (AD-5D) derived from the QOL-AD. METHODS AND ANALYSIS Discrete choice experiments with duration (DCETTO) and best-worst scaling health state valuation tasks will be administered to a representative sample of 2000 members of the Australian general population via an online survey and to 250 dementia dyads (250 people with dementia and their carers) via face-to-face interview. A multinomial (conditional) logistic framework will be used to analyse responses and produce the utility algorithm for the AD-5D. ETHICS AND DISSEMINATION The algorithms developed will enable prospective and retrospective economic evaluation of any treatment or intervention targeting people with dementia where the QOL-AD has been administered and will be available online. Results will be disseminated through journals that publish health economics articles and through professional conferences. This study has ethical approval.

Abstract
OBJECTIVE The aim of this article was to review the literature around Australian medical student attitudes towards older people. METHODS An Ovid cross-search and SCOPUS search were performed using keywords such as 'Attitude', 'Medical Student' and 'Aged or Older or Elderly'. RESULTS Several recent studies have investigated the attitudes of Australian medical students towards older people. Baseline attitudes at two medical schools were positive. Three studies quantified attitude improvement after curriculum intervention. All the studies used US-developed instruments, which have not been validated in Australia. Qualitative studies have described mixed attitudes towards older people: negative themes included nihilism, paternalism, communication issues, greater morbidity and reduced quality of life. Positively, students placed value on clinical decision-making and critical reflection during residential aged care placements. CONCLUSION Australian medical students' attitudes towards older people are mixed and not well understood based on quantitative measures developed for use in the US and on qualitative evidence. Future research in this area requires a reliable and locally-validated instrument.

Slow gait speed is associated with executive function decline in older people with mild to moderate dementia: A one year longitudinal study. Arch Gerontol Geriatr 2017; 73:148-153. [PMID: 28818760 DOI: 10.1016/j.archger.2017.07.023] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Revised: 07/20/2017] [Accepted: 07/24/2017] [Indexed: 01/28/2023]
Abstract
OBJECTIVES This study aimed to document change in neuropsychological, physical and functional performance over one year and to investigate the relationship between baseline gait speed and cognitive decline in this period in older people with dementia. METHODS One hundred and seventy-seven older people with dementia (Mini-Mental State Examination 11-23; Addenbrooke's Cognitive Examination-Revised <83) residing in the community or low level care facility completed baseline neuropsychological, physical and functional assessments. Of these, 134 participants agreed to reassessment of the above measures one year later. RESULTS Overall, many neuropsychological, physical and functional performance measures declined significantly over the one year study period. Baseline gait speed was significantly associated with decline in verbal fluency (B(109)=2.893, p=0.046), specifically phonemic/letter fluency (B(109)=2.812, p=0.004) while controlling for age, education, dementia drug use and baseline cognitive performance. There was also a trend for an association between baseline gait speed and decline in clock drawing performance (B(107)=0.601, p=0.071). CONCLUSIONS Older people with mild to moderate dementia demonstrate significant decline in neuropsychological, physical and functional performance over one year. Baseline gait speed is associated with decline in executive function over one year, suggesting shared pathways/pathology between gait and cognition.

Appropriate care for older people with cognitive impairment in hospital. Med J Aust 2017; 205:S12-S15.

Abstract
More than half of the patients in adult hospitals are over 65 years of age. Although not a normal part of ageing, many older people will present to hospital with cognitive impairment (dementia or delirium) along with other complex comorbidities. Older people, and particularly those with dementia, are also at increased risk of developing delirium during their hospital stay. Delirium has serious short and long term consequences, such as increased mortality, falls, accelerated functional and cognitive decline, and earlier entry to residential care. Appropriate delirium care consists of introducing evidence-based prevention strategies for all patients at risk. For patients with delirium, it is crucial that delirium is not missed and that the underlying causes are identified and treated. Screening, assessment and a systematic workup is vital. As well as treating the underlying medical and surgical causes, the involvement of family members and a calm, safe environment are important. Patients with cognitive impairment should receive person-centred, goal-directed care so that their particular risks of harm are identified and minimised, and their care is aligned with their preferences and is medically appropriate for their circumstances. Three de-identified, composite case scenarios illustrate, respectively, the role of medicines in causing delirium, how family members can assist in evaluation, and the importance of the appropriate management of post-operative delirium.

Abstract
OBJECTIVES To explore the relationship between cognitive performance and falls in older people with mild to moderate cognitive impairment (CI) by investigating the mediational effects of medical, medication, neuropsychological, and physiological factors. DESIGN Secondary analysis, prospective cohort study. SETTING Community and low-level care. PARTICIPANTS 177 older people (aged 82 ± 7 years) with mild to moderate CI (MMSE 11-23; ACE-R < 83). MEASUREMENTS Global cognition and six neuropsychological domains (memory, language, visuospatial, processing speed, executive function [EF], and affect) were assessed. Participants also underwent sensorimotor and balance assessments. Falls were recorded prospectively for 12 months. RESULTS The EF domain was most strongly associated with multiple falls (relative risk [RR]: 1.50, 95% CI: 1.18-1.91). Global cognition was not associated with falls (RR: 1.09, 95% CI: 0.92-1.30). Additional analyses showed that participants with poorer EF (median cutpoint) were more likely to be taking centrally acting medications and were less physically active. They also had significantly worse vision, reaction time, knee extension strength, balance (postural sway, controlled leaning balance), and higher physiological fall risk scores. Participants with poorer EF were 1.5 times (RR: 1.50, 95% CI: 1.03-2.18) more likely to have multiple falls. Mediational analyses demonstrated that reaction time and postural sway reduced the relative risk of EF on multiple falls by 31% (RR: 1.19, 95% CI: 0.81-1.74). CONCLUSIONS Within this sample of older people with mild to moderate CI, poorer EF increased the risk of multiple falls. This relationship was mediated by reaction time and postural sway,suggesting cognitively impaired older people with poorer EF may benefit from fall prevention programs targeting these mediating factors.

Abstract
QUESTION What is the effect of a multifactorial intervention on frailty and mobility in frail older people who comply with their allocated treatment? DESIGN Secondary analysis of a randomised, controlled trial to derive an estimate of complier average causal effect (CACE) of treatment. PARTICIPANTS A total of 241 frail community-dwelling people aged ≥ 70 years. INTERVENTION Intervention participants received a 12-month multidisciplinary intervention targeting frailty, with home exercise as an important component. Control participants received usual care. OUTCOME MEASURES Primary outcomes were frailty, assessed using the Cardiovascular Health Study criteria (range 0 to 5 criteria), and mobility measured using the 12-point Short Physical Performance Battery. Outcomes were assessed 12 months after randomisation. The treating physiotherapist evaluated the amount of treatment received on a 5-point scale. RESULTS 216 participants (90%) completed the study. The median amount of treatment received was 25 to 50% (range 0 to 100). The CACE (ie, the effect of treatment in participants compliant with allocation) was to reduce frailty by 1.0 frailty criterion (95% CI 0.4 to 1.5) and increase mobility by 3.2 points (95% CI 1.8 to 4.6) at 12 months. The mean CACE was substantially larger than the intention-to-treat effect, which was to reduce frailty by 0.4 frailty criteria (95% CI 0.1 to 0.7) and increase mobility by 1.4 points (95% CI 0.8 to 2.1) at 12 months. CONCLUSION Overall, compliance was low in this group of frail people. The effect of the treatment on participants who comply with allocated treatment was substantially greater than the effect of allocation on all trial participants.

Abstract
Rehabilitation approaches to frailty are in the early stages of development. Frailty also shows promise as a prognostic indicator for rehabilitation programs, similar to its application in other areas of medicine. However, care should be taken not to exclude frail older people from rehabilitation, as has been the case at some centers for people with cognitive impairment or very severe disability. There are clear theoretical reasons to expect that a rehabilitation approach will be effective. Some experimental data are also available suggesting that rehabilitation is effective in frail and pre-frail older people. The principles of a frailty intervention program that have been demonstrated to be clinically and economically effective are as follows: first, frailty can be mitigated; second, support needs are individually addressed; third, the interventions aim to improve physical, cognitive and social functioning; fourth, support has to be delivered over a long time period; and finally, systems must facilitate consistent management. Most frail older people are encouraged and supported to adhere to their intervention plan. It is important to recognize the needs of families and/or carers and to engage with them.

Abstract
INTRODUCTION Frailty is a major concern due to its costly and widespread consequences, yet evidence of effective interventions to delay or reduce frailty is lacking. Our previous study found that a multifactorial intervention was feasible and effective in reducing frailty in older people who were already frail. Identifying and treating people in the pre-frail state may be an effective means to prevent or delay frailty. This study describes a randomised controlled trial that aims to evaluate the effectiveness of a multifactorial intervention on development of frailty in older people who are pre-frail. METHODS AND ANALYSIS A single centre randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. Two hundred and thirty people aged above 70 who meet the Cardiovascular Health Study frailty criteria for pre-frailty, reside in the community and are without severe cognitive impairment will be recruited. Participants will be randomised to receive a multifactorial intervention or usual care. The intervention group will receive a 12-month interdisciplinary intervention targeting identified characteristics of frailty and problems identified during geriatric assessment. Participants will be followed for a 12-month period. Primary outcome measures will be degree of frailty measured by the number of Cardiovascular Health Study frailty criteria present, and mobility measured with the Short Physical Performance Battery. Secondary outcomes will include measures of mobility, mood and use of health and community services. ETHICS AND DISSEMINATION The study was approved by the Northern Sydney Local Health District Health Research Ethics Committee (1207-213M). The findings will be disseminated through scientific and professional conferences, and in peer-reviewed journals.

Abstract
BACKGROUND accurate and practical assessment methods for assessing appendicular skeletal muscle (ASM) is of clinical importance for the diagnosis of geriatric syndromes associated with skeletal muscle wasting. OBJECTIVES the purpose of this study was to develop and cross-validate novel anthropometric prediction equations for the estimate of ASM in older adults post-surgical fixation for hip fracture, using dual-energy X-ray absorptiometry (DEXA) as the criterion measure. SUBJECTS community-dwelling older adults (aged ≥65 years) recently hospitalised for hip fracture. SETTING participants were recruited from hospital in the acute phase of recovery. DESIGN validation measurement study. MEASUREMENTS a total of 79 hip fracture patients were involved in the development of the regression models (MD group). A further 64 hip fracture patients also recruited in the early phase of recovery were used in the cross-validation of the regression models (CV group). Multiple linear regression analyses were undertaken in the MD group to identify the best performing prediction models. The linear coefficient of determination (R(2)) in addition to the standard error of the estimate (SEE) were calculated to determine the best performing model. Agreement between estimated ASM and ASMDEXA in the CV group was assessed using paired t-tests with the 95% limits of agreement (LOA) assessed using Bland-Altman analyses. RESULTS the mean age of all the participants was 82.1 ± 7.3 years. The best two prediction models are presented as follows: ASMPRED-EQUATION_1: 22.28 - (0.069 * age) + (0.407 * weight) - (0.807 * BMI) - (0.222 * MAC) (adjusted R(2): 0.76; SEE: 1.80 kg); ASMPRED-EQUATION_2: 16.77 - (0.036 * age) + (0.385 * weight) - (0.873 * BMI) (adjusted R(2): 0.73; SEE: 1.90 kg). The mean bias from the CV group between ASMDEXA and the predictive equations is as follows: ASMDEXA - ASMPRED-EQUATION_1: 0.29 ± 2.6 kg (LOA: -4.80, 5.40 kg); ASMDEXA - ASMPRED-EQUATION_2: 0.13 ± 2.5 kg (LOA: -4.77, 5.0 kg). No significant difference was observed between measured ASMDEXA and estimated ASM (ASMDEXA: 16.4 ± 3.9 kg; ASMPRED-EQUATION_1: 16.7 ± 3.2 kg (P = 0.379); ASMPRED-EQUATION_2: 16.6 ± 3.2 kg (P = 0.670)). CONCLUSIONS we have developed and cross-validated novel anthropometric prediction equations against DEXA for the estimate of ASM designed for application in older orthopaedic patients. Our equation may be of use as an alternative to DEXA in the diagnosis of skeletal muscle wasting syndromes. Further validation studies are required to determine the clinical utility of our equation across other settings, including hip fracture patients admitted from residential care, and also with a longer-term follow-up.

Economic evaluation of a multifactorial, interdisciplinary intervention versus usual care to reduce frailty in frail older people. J Am Med Dir Assoc 2014; 16:41-8.

Abstract
OBJECTIVE To compare the costs and cost-effectiveness of a multifactorial interdisciplinary intervention versus usual care for older people who are frail. DESIGN Cost-effectiveness study embedded within a randomized controlled trial. SETTING Community-based intervention in Sydney, Australia. PARTICIPANTS A total of 241 community-dwelling people 70 years or older who met the Cardiovascular Health Study criteria for frailty. INTERVENTION A 12-month multifactorial, interdisciplinary intervention targeting identified frailty characteristics versus usual care. MEASUREMENTS Health and social service use, frailty, and health-related quality of life (EQ-5D) were measured over the 12-month intervention period. The difference between the mean cost per person for 12 months in the intervention and control groups (incremental cost) and the ratio between incremental cost and effectiveness were calculated. RESULTS A total of 216 participants (90%) completed the study. The prevalence of frailty was 14.7% lower in the intervention group compared with the control group at 12 months (95% CI 2.4%-27.0%; P = .02). There was no significant between-group difference in EQ-5D utility scores. The cost for 1 extra person to transition out of frailty was $A15,955 (at 2011 prices). In the "very frail" subgroup (participants met >3 Cardiovascular Health Study frailty criteria), the intervention was both more effective and less costly than the control. A cost-effectiveness acceptability curve shows that the intervention would be cost-effective with 80% certainty if decision makers were willing to pay $A50,000 per extra person transitioning from frailty. In the very frail subpopulation, this reduced to $25,000. CONCLUSION For frail older people residing in the community, a 12-month multifactorial intervention provided better value for money than usual care, particularly for the very frail, in whom it has a high probability of being cost saving, as well as effective.

Abstract
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.

Abstract
BACKGROUND Interventions that enhance mobility in frail older people are needed to maintain health and independence, yet definitive evidence of effective interventions is lacking. Our objective was to assess the impact of a multifactorial intervention on mobility-related disability in frail older people. METHODS We conducted a randomised, controlled trial with 241 frail community-dwelling older people in Sydney, Australia. Participants were classified as frail using the Cardiovascular Health Study definition, did not have severe cognitive impairment and were recently discharged from an aged care and rehabilitation service. The experimental group received a 12 month multifactorial, interdisciplinary intervention targeting identified frailty components. Two physiotherapists delivered a home exercise program targeting mobility, and coordinated management of psychological and medical conditions with other health professionals. The control group received usual care. Disability in the mobility domain was measured at baseline and at 3 and 12 months using the International Classification of Functioning, Disability and Health framework. Participation (involvement in life situations) was assessed using the Life Space Assessment and the Goal Attainment Scale. Activity (execution of mobility tasks) was measured using the 4-metre walk and self-report measures. RESULTS The mean age of participants was 83.3 years (SD: 5.9 years). Of the participants recruited, 216 (90%) were followed-up at 12 months. At this time point, the intervention group had significantly better scores than the control group on the Goal Attainment Scale (odds ratio 2.1; 95% confidence interval (CI) 1.3 to 3.3, P = 0.004) and Life Space Assessment (4.68 points, 95% CI 1.4 to 9.9, P = 0.005). There was no difference between groups on the global measure of participation or satisfaction with ability to get out of the house. At the activity level, the intervention group walked 0.05 m/s faster over 4 m (95% CI 0.0004 to 0.1, P = 0.048) than the control group, and scored higher on the Activity Measure for Post Acute Care (P < 0.001). CONCLUSIONS The intervention reduced mobility-related disability in frail older people. The benefit was evident at both the participation and activity levels of mobility-related disability.

Abstract
BACKGROUND cognitive decline and muscle weakness are prevalent health conditions in elderly people. We hypothesised that cognitive decline precedes muscle weakness. OBJECTIVE to analyse the temporal relationship between cognitive performance and handgrip strength in oldest old people. DESIGN prospective population-based 4-year follow-up study. SUBJECTS a total of 555 subjects, all aged 85 years at baseline, were included into the study. METHODS handgrip strength measured at age 85 and 89 years. Neuropsychological test battery to assess global cognitive performance, attention, processing speed and memory at baseline and repeated at age 89 years. Associations between handgrip strength and cognitive performance were analysed by repeated linear regression analysis adjusted for common confounders. RESULTS at age 85 and 89 years, better cognitive performance was associated with higher handgrip strength (all, P<0.03), except for attention. There was no longitudinal association between baseline handgrip strength and cognitive decline (all, P>0.10), except for global cognitive performance (P=0.007). Better cognitive performance at age 85 years was associated with slower decline in handgrip strength (all, P<0.01) after adjustment for common confounders. CONCLUSION baseline cognitive performance was associated with decline in handgrip strength, whereas baseline handgrip strength was not associated with cognitive decline. Our results suggest that cognitive decline precedes the onset of muscle weakness in oldest old people.

Abstract
Background An increasing demand for acute care services due in part to rising proportions of older people and increasing rates of chronic diseases has led to new models of post-acute care for older people that offer coordinated discharge, ongoing support and often a focus on functional restoration. Overall, review of the literature suggests there is considerable uncertainty around the effectiveness and resource implications of the various model configurations and delivery approaches. In this paper, we review the current evidence on the efficacy of such programs, using the Australian Transition Care Program as a case study. Discussion The Australian Transition Care Program was established at the interface of the acute and aged care sectors with particular emphasis on transitions between acute and community care. The program is intended to enable a significant proportion of care recipients to return home, rather than prematurely enter residential aged care, optimize their functional capacity, and reduce inappropriate extended lengths of hospital stay for older people. Broadly, the model is configured and targeted in accordance with programs reported in the international literature to be effective. Early evaluations suggest good acceptance of the program by hospitals, patients and staff. Ultimately, however, the program's place in the array of post-acute services should be determined by its demonstrated efficacy relative to other services which cater for similar patient groups. Summary Currently there is a lack of robust evaluation to provide convincing evidence of efficacy, either from a patient outcome or cost reduction perspective. As the program expands and matures, there will be opportunity to scrutinise the systematic effects, with lessons for both Australian and international policy makers and clinical leaders.

Abstract
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.

Abstract
OBJECTIVE To determine the effectiveness of interdisciplinary rehabilitation for women with hip fracture who were residents of nursing homes. DESIGN Randomised controlled trial. SUBJECTS Eleven cognitively impaired women with hip fracture who were previously ambulant. METHODS Participants were randomly allocated to usual care (discharge back to the nursing home soon after surgery to the hip fracture) or an inpatient interdisciplinary rehabilitation program. RESULTS Participants were severely cognitively impaired and the majority used a walking aid prior to fracturing their hip. There was one early death, and at final follow up (4 months after hip fracture) median (range) Barthel Index was 28 (0-82) for control group and 68 (0-88) for the intervention group. CONCLUSION No definite conclusion can be drawn about the effectiveness of the intervention because of its premature termination. However, the study established that it is feasible to provide an interdisciplinary rehabilitation for older people with hip fracture and severe disablement.

Abstract
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.

Abstract
OBJECTIVE To describe fall-related injuries due to pets in an older population. DESIGN Case series. PARTICIPANTS AND SETTING Patients aged 75 years and over presenting to the emergency department of a metropolitan hospital in northern Sydney over 18 months, with a fracture directly related to their pet. MAIN OUTCOME MEASURES Type of fracture; circumstances of injury. RESULTS 16 cases (mean patient age, 81 years) are described; 13 (81%) involved women. Animals of five species were involved, with cats and dogs being the most common pet hazard. CONCLUSIONS Pets are a potential environmental hazard in the occurrence of fall-related injuries in older people, with dogs and cats most likely to be involved. Women appear more likely than men to be injured.

Abstract
BACKGROUND Hip protectors can prevent many hip fractures in older persons at high risk for falling. Few published studies have investigated the use of hip protectors in community-dwelling older persons, and the level of adherence with their use, and predictors of adherence in this setting, are not clear. The aim of this study was to report the predictors of adherence and the level of adherence with the use of hip protectors in frail community-dwelling older women. METHODS This cohort study of the intervention group of a randomized, controlled trial recruited participants from aged care health services in urban areas of northern Sydney, Australia. Participants were 302 women who were 74 years or older (mean age, 83 years) and who had 2 or more falls or 1 fall requiring hospital admission in the previous year and who lived in their own homes. The main outcome measure was adherence with the use of hip protectors. RESULTS Adherence was approximately 53% during the 2 years of the study, and hip protectors were worn at the time of 51% of falls. The significant independent predictors of nonadherence with hip protector use were lower self-efficacy for hip protector use (odds ratio [OR], 0.51; 95% confidence interval [CI],.33 to.79), higher number of perceived barriers to hip protector use (OR, 0.52; 95% CI, .38 to.72), and lower self-rated health (OR, 0.71; 95% CI, .55 to.93). CONCLUSIONS Three easily measured factors independently predicted subsequent adherence with hip protector use. These findings may form the basis for strategies to improve adherence with the use of hip protectors and with other types of treatment or preventive strategies in older persons.

Abstract
Definitions of adherence, also termed compliance, with use of hip protectors have varied in published studies, making interpretation of results difficult. This paper proposes standard definitions of adherence with the use of hip protectors. Adherence is the wearing of hip protectors in accordance with the recommendations of the study protocol, and is measured as the amount of time hip protectors are worn. When reporting use of hip protectors in clinical trials investigators should indicate the specific definition of adherence used, explicitly state the recommendation that was made for use of hip protectors during the study, and describe the methods of recording adherence.

Abstract
OBJECTIVES To investigate the efficacy and effectiveness of hip protectors in frail community living older women. DESIGN Randomised controlled trial. SETTING Aged care health services in New South Wales, Australia. PATIENTS 600 women 74 years of age or more (mean age 83 years), who had two or more falls or one fall requiring hospital admission in the previous year, and who lived in their own homes. INTERVENTION Use of hip protectors. MAIN OUTCOME MEASURES Adherence with use of hip protectors, falls, incidence of hip fracture, and adverse effects of use of hip protectors. RESULTS Adherence was approximately 53% over the duration of the study and hip protectors were worn at the time of 51% of falls in the intervention group. The risk of hip fracture when falling while wearing hip protectors, compared with a fall with no hip protectors in place, was significantly reduced (relative risk (RR) 0.23, 95% confidence interval (CI) 0.08 to 0.67). On an intention to treat analysis, 21 and 22 hip fractures occurred in the intervention and control groups respectively (adjusted RR 0.92, 95% CI 0.51 to 1.68). Three users of hip protectors sustained a hip fracture while wearing properly applied protectors, while 16 hip protector users (5%) developed minor local complications. CONCLUSIONS Hip protectors prevent hip fractures in community dwelling older women if worn at the time of a fall. The overall effectiveness of hip protectors was not established in this study, because of incomplete adherence with use of the protectors, and limited statistical power.

Abstract
Older people make up the majority of participants in general rehabilitation programs. Stroke and hip fracture are the major diagnostic groups. Most older people with significant disability of recent onset have the potential to benefit from rehabilitation. Assessing an older person's premorbid functional and cognitive status, which are strong determinants of rehabilitation outcome, is an important component of management. The major goals of rehabilitation for older people are mobility and self-care without the assistance of another person. Evidence suggests that rehabilitation for older people involving a coordinated multidisciplinary team of health professionals (including nurses and doctors) is effective. Contemporary rehabilitation practice is not confined to traditional inpatient rehabilitation units; it also occurs in the community and other non-hospital settings, and involves general practitioners.
