Characterising Australian memory clinics: current practice and service needs informing national service guidelines.

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.

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.

Reaction Time and Postural Sway Modify the Effect of Executive Function on Risk of Falls in Older People with Mild to Moderate Cognitive Impairment.

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.

A home-based, carer-enhanced exercise program improves balance and falls efficacy in community-dwelling older people with dementia.

BACKGROUND: Older people with dementia are at increased risk of physical decline and falls. Balance and mood are significant predictors of falls in this population. The aim of this study was to determine the effect of a tailored home-based exercise program in community-dwelling older people with dementia. METHODS: Forty-two participants with mild to moderate dementia were recruited from routine health services. All participants were offered a six-month home-based, carer-enhanced, progressive, and individually tailored exercise program. Physical activity, quality of life, physical, and psychological assessments were administered at the beginning and end of the trial. RESULTS: Of 33 participants (78.6%) who completed the six-month reassessment ten (30%) reported falls and six (18%) multiple falls during the follow-up period. At reassessment, participants had better balance (sway on floor and foam), reduced concern about falls, increased planned physical activity, but worse knee extension strength and no change in depression scores. The average adherence to the prescribed exercise sessions was 45% and 22 participants (52%) were still exercising at trial completion. Those who adhered to ≥70% of prescribed sessions had significantly better balance at reassessment compared with those who adhered to <70% of sessions. CONCLUSIONS: This trial of a tailored home-based exercise intervention presents preliminary evidence that this intervention can improve balance, concern about falls, and planned physical activity in community-dwelling older people with dementia. Future research should determine whether exercise interventions are effective in reducing falls and elucidate strategies for enhancing uptake and adherence in this population.

Appropriate care for older people with cognitive impairment in hospital.

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.

Effect of a multifactorial, interdisciplinary intervention on risk factors for falls and fall rate in frail older people: a randomised controlled trial.

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.

Appendicular skeletal muscle in hospitalised hip-fracture patients: development and cross-validation of anthropometric prediction equations against dual-energy X-ray absorptiometry.

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.

Hospital-Based Health Professionals' Perceptions of Frailty in Older People.

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 semistructured interviews were conducted with health professionals working in multidisciplinary teams on geriatric and rehabilitation wards in Adelaide and Sydney, Australia. Interviews were audio recorded, transcribed, and coded by 2 researchers. A codebook was created and interviews were recoded 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, 8 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.

Frailty evidence-practice gaps in acute care hospitals.

OBJECTIVES: Frailty is common in hospitalised older people. Clinical practice guidelines for the management of frailty provide recommendations for identification and management; however, adoption into practice in hospitals is limited. This study identified and quantified the evidence-practice gap between frailty guidelines and clinical practice in two hospitals using an audit tool. METHODS: A cross-sectional audit of medical records of frail older patients admitted to two hospitals was conducted. Data were collected using an audit tool based on the Asia Pacific Clinical Practice Guidelines for frailty management. Data were analysed using descriptive statistics and inter-rater reliability of the tool was assessed. RESULTS: Auditing of n = 70 electronic medical records showed that assessment of frailty in the acute setting did not regularly occur (17%). Few participants received guideline-recommended interventions. Physiotherapy treatment was limited, with 23% of participants receiving progressive resistance strength training. Gaps exist in provision of nutritional supplementation (26%) with limited recordings of weight during the admission for 10% of participants. Pharmacy review of medications was consistently documented on admission (84%) and discharge (93%). Vitamin D was prescribed for 57% of participants. Inter-rater reliability showed a high level of agreement using the audit tool. CONCLUSIONS: An audit tool was feasible to assess frailty evidence-practice gaps in the hospital setting. Further understanding of the contextual barriers is needed to inform implementation strategies (dedicated staffing, education and training and ongoing audit of practice cycles) for the uptake of frailty guidelines in hospital settings.

Effect of cognitive training on cognitive function in community-dwelling older people with mild-to-moderate dementia: A single-blind randomised controlled trial.

OBJECTIVES: The purpose of this assessor-blinded, randomised controlled trial was to determine the effect of computerised cognitive training (CT) on executive function, processing speed and working memory in 61 people with mild-to-moderate dementia. METHODS: The primary outcomes were forward Digit Span and Trail Making Tests (TMT) at the completion of the 6-month intervention. Secondary outcomes included cognitive and physical performance, rate of falls, participant and caregiver's quality of life and usability and adherence to the CT program. The study was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12617000364370). RESULTS: Intervention group (n = 31) participants averaged 81 min of CT per week, and system usability scores were acceptable (participants: 68.8 ± 22.1; caregivers: 79.4 ± 23.5). There were no statistically significant differences in cognitive or physical performance outcomes between the intervention and control groups at 6- or 12-months (between-group differences [95% CI] for primary outcomes at 6-months: Forward Digit Span -0.3 [-0.8, 0.3]; TMT-A 2.7 s [-14.1, 19.5]; TMT-B -17.1 s [-79.3, 45.2]). At the 12-month follow-up reassessment, the intervention group reported significantly more depressive symptoms and had lower caregiver-rated participant quality of life and higher caregiver quality of life compared to control. CONCLUSIONS: This study showed no benefit of the CT program on working memory, processing speed and executive function. Future studies are required to better understand how CT can be used to improve cognitive and physical functioning in older people with mild-moderate dementia.

A multifactorial interdisciplinary intervention reduces frailty in older people: randomized trial.

BACKGROUND: 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. METHODS: We conducted a single center, randomized, controlled trial among older people who were frail in Sydney, Australia. One group received an intervention targeting the identified characteristics of frailty, whereas the comparison group received the usual health care and support services. Outcomes were assessed by raters masked to treatment allocation at 3 and 12 months after study entry. The primary outcomes were frailty as assessed by the Cardiovascular Health Study criteria, and mobility as assessed by the Short Physical Performance Battery. Secondary outcome measures included disability, depressive symptoms and health-related quality of life. RESULTS: A total of 216 participants (90%) completed the study. Overall, 68% of participants were women and the mean age was 83.3 years (standard deviation, 5.9). In the intention-to-treat analysis, the between-group difference in frailty was 14.7% at 12 months (95% confidence interval: 2.4%, 27.0%; P = 0.02). The score on the Short Physical Performance Battery, in which higher scores indicate better physical status, was stable in the intervention group and had declined in the control group; with the mean difference between groups being 1.44 (95% confidence interval, 0.80, 2.07; P <0.001) at 12 months. There were no major differences between the groups with respect to secondary outcomes. The few adverse events that occurred were exercise-associated musculoskeletal symptoms. CONCLUSIONS: Frailty and mobility disability can be successfully treated using an interdisciplinary multifaceted treatment program.

Implementation of a frailty intervention in the transition from hospital to home: a realist process evaluation protocol for the FORTRESS trial.

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).

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).

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.

Effect of a multifactorial interdisciplinary intervention on mobility-related disability in frail older people: randomised controlled trial.

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.

Temporal relationship between handgrip strength and cognitive performance in oldest old people.

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.

How effective are programs at managing transition from hospital to home? A case study of the Australian Transition Care Program.

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.

Treating frailty--a practical guide.

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.
