An Empirical Comparison of the EQ-5D-5L, DEMQOL-U and DEMQOL-Proxy-U in a Post-Hospitalisation Population of Frail Older People Living in Residential Aged Care

OBJECTIVE

To empirically compare the measurement properties of the DEMQOL-U and DEMQOL-Proxy-U instruments to the EQ-5D-5L and its proxy version (CEQ-5D-5L) in a population of frail older people living in residential aged care in the post-hospitalisation period following a hip fracture.

METHODS

A battery of instruments to measure health-related quality of life (HRQoL), cognition, and clinical indicators of depression, pain and functioning were administered at baseline and repeated at 4 weeks' follow-up. Descriptive summary statistics were produced and psychometric analyses were conducted to assess the levels of agreement, convergent validity and known group validity between clinical indicators and HRQoL measures.

RESULTS

There was a large divergence in mean (SD) utility scores at baseline for the EQ-5D-5L and DEMQOL-U [EQ-5D-5L mean 0.21 (0.19); DEMQOL-U mean 0.79 (0.14)]. At 4 weeks' follow-up, there was a marked improvement in EQ-5D-5L scores whereas DEMQOL-U scores had deteriorated. [EQ-5D-5L mean 0.45 (0.38); DEMQOL-U mean 0.58 (0.38)]. The EQ-5D and CEQ-5D-5L were more responsive to the physical recovery trajectory experienced by frail older people following surgery to repair a fractured hip, whereas the DEMQOL-U and DEMQOL-Proxy-U appeared more responsive to the changes in delirium and dementia symptoms often experienced by frail older people in this period.

CONCLUSIONS

This study presents important insights into the HRQoL of a relatively under-researched population of post-hospitalisation frail older people in residential care. Further research should investigate the implications for economic evaluation of self-complete versus proxy assessment of HRQoL and the choice of preference-based instrument for the measurement and valuation of HRQoL in older people exhibiting cognitive decline, dementia and other co-morbidities.

The diagnostic accuracy of the Kimberley Indigenous Cognitive Assessment (KICA) tool: a systematic review

OBJECTIVES

The objective of this study was to conduct a systematic review of evidence for the accuracy of the Kimberley Indigenous Cognitive Assessment (KICA) tool in supporting the diagnosis of dementia in Indigenous Australian populations.

METHODS

Cross-sectional diagnostic accuracy studies of the KICA with an appropriate reference standard published to November 2015 were included. Comparison to an alternative cognitive assessment tool was required in non-remote populations. Case control analyses were excluded.

RESULTS

Four studies were included: one of the KICA-Cog and KICA-Carer, one of the KICA Screen, and two of the modified-KICA. All tools developed for remote populations had a sensitivity of ≥76% and a specificity of ≥71% for the diagnosis of dementia. The KICA-Cog and KICA-Carer conducted in series had the highest sensitivity and specificity (91% and 94% respectively). In an urban and regional population, the mKICA had similar accuracy to the Mini-Mental State Examination (MMSE) (AUC 0.93, 95% CI 0.88-0.99 vs 0.94, 95% CI 0.89-0.99). Key risk of bias limitations related to lack of pre-determined cut-points and population selection methods.

CONCLUSION

The use of the KICA in remote Indigenous Australians may assist in timely diagnosis of dementia in this population. Using the KICA-Cog and KICA-Carer in series may maximise specificity, decreasing false positive results without compromising sensitivity.

Struggling to maintain individuality - Describing the experience of food in nursing homes for people with dementia

PURPOSE OF THE STUDY

To describe the food and dining experience of people with cognitive impairment and their family members in nursing homes.

DESIGN AND METHODS

Interviews and focus groups with people with cognitive impairment and their family members (n=19). Thematic analysis was undertaken using NVivo10 data analysis software package to determine key themes.

RESULTS

The main themes identified tracked a journey for people with cognitive impairment in nursing homes, where they initially sought to have their individual needs and preferences recognised and heard, expressed frustration as they perceived growing barriers to receiving dietary care which met their preferences, and ultimately described a deterioration of the amount of control and choice available to the individual with loss of self-feeding ability and dysphagia.

IMPLICATIONS

Further consideration of how to incorporate individualised dietary care is needed to fully implement person-centred care and support the quality of life of those receiving nursing home care.

Where's the evidence? a systematic review of economic analyses of residential aged care infrastructure

BACKGROUND

Residential care infrastructure, in terms of the characteristics of the organisation (such as proprietary status, size, and location) and the physical environment, have been found to directly influence resident outcomes. This review aimed to summarise the existing literature of economic evaluations of residential care infrastructure.

METHODS

A systematic review of English language articles using AgeLine, CINAHL, Econlit, Informit (databases in Health; Business and Law; Social Sciences), Medline, ProQuest, Scopus, and Web of Science with retrieval up to 14 December 2015. The search strategy combined terms relating to nursing homes, economics, and older people. Full economic evaluations, partial economic evaluations, and randomised trials reporting more limited economic information, such as estimates of resource use or costs of interventions were included. Data was extracted using predefined data fields and synthesized in a narrative summary to address the stated review objective.

RESULTS

Fourteen studies containing an economic component were identified. None of the identified studies attempted to systematically link costs and outcomes in the form of a cost-benefit, cost-effectiveness, or cost-utility analysis. There was a wide variation in approaches taken for valuing the outcomes associated with differential residential care infrastructures: 8 studies utilized various clinical outcomes as proxies for the quality of care provided, and 2 focused on resident outcomes including agitation, quality of life, and the quality of care interactions. Only 2 studies included residents living with dementia.

CONCLUSIONS

Robust economic evidence is needed to inform aged care facility design. Future research should focus on identifying appropriate and meaningful outcome measures that can be used at a service planning level, as well as the broader health benefits and cost-saving potential of different organisational and environmental characteristics in residential care.

Advancing aged care: a systematic review of economic evaluations of workforce structures and care processes in a residential care setting

Long-term care for older people is provided in both residential and non-residential settings, with residential settings tending to cater for individuals with higher care needs. Evidence relating to the costs and effectiveness of different workforce structures and care processes is important to facilitate the future planning of residential aged care services to promote high quality care and to enhance the quality of life of individuals living in residential care. A systematic review conducted up to December 2015 identified 19 studies containing an economic component; seven included a complete economic evaluation and 12 contained a cost analysis only. Key findings include the potential to create cost savings from a societal perspective through enhanced staffing levels and quality improvement interventions within residential aged care facilities, while integrated care models, including the integration of health disciplines and the integration between residents and care staff, were shown to have limited cost-saving potential. Six of the 19 identified studies examined dementia-specific structures and processes, in which person-centred interventions demonstrated the potential to reduce agitation and improve residents’ quality of life. Importantly, this review highlights methodological limitations in the existing evidence and an urgent need for future research to identify appropriate and meaningful outcome measures that can be used at a service planning level.

Reorganization of the primary motor cortex following lower-limb amputation for vascular disease: a pre-post-amputation comparison

PURPOSE

This study compared bilateral corticomotor and intracortical excitability of the primary motor cortex (M1), pre- and post-unilateral transtibial amputation.

METHOD

Three males aged 45, 55, and 48 years respectively who were scheduled for elective amputation and thirteen (10 male, 3 female) healthy control participants aged 58.9 (SD 9.8) were recruited. Transcranial magnetic stimulation assessed corticomotor and intracortical excitability of M1 bilaterally. Neurophysiological assessments were performed 10 (SD 7) days prior to surgery and again at 10 (SD 3) days following surgery. Data were analyzed descriptively and objectively compared to 95% confidence intervals from control data.

RESULTS

Prior to amputation, all three patients demonstrated stronger short-latency intracortical inhibition evoked from M1 ipsilateral to the affected limb and reduced long-latency intracortical inhibition evoked from M1 contralateral to the affected limb compared to control subjects. Following amputation, short-latency intracortical inhibition was reduced in both M1s and long-latency intracortical inhibition was reduced for the ipsilateral M1. Single-pulse motor evoked potential amplitude and motor thresholds were similar pre-to-post amputation.

CONCLUSIONS

Modulation of intracortical excitability shortly following amputation indicates that the cortical environment may be optimized for reorganization in the acute post-amputation period which might be significant for learning to support prosthetic mobility. Implications for Rehabilitation Amputation of a lower-limb is associated with extensive reorganization at the level of the cortex. Reorganization occurs in the acute post-amputation period implying a favorable cortical environment for recovery. Rehabilitation or brain interventions may target the acute pre-prosthetic post-amputation period to optimize recovery.

Clinical practice guidelines and principles of care for people with dementia in Australia

BACKGROUND

Dementia is a national health priority in Australia. Most people with dementia are over the age of 65 years, have a number of comorbidities and experience a trajectory of functional decline. General practitioners (GPs) have an important role in the diagnosis and management of people with dementia. The Cognitive Decline Partnership Centre's Clinical practice guidelines and principles of care for people with dementia (Guidelines) was recently approved by the National Health and Medical Research Council (NHMRC).

OBJECTIVE

This article describes the recommendations within the Guidelines that are of greatest relevance to GPs, including those addressing diagnosis, living well, managing behavioural and psychological symptoms, supporting carers, and the palliative approach.

DISCUSSION

The Guidelines synthesise current evidence in dementia care and emphasise: timely diagnosis; encouraging the person with dementia to exercise, eat well and keep doing as much for themselves as possible; supporting and training carers to provide care; and reducing prescription of potentially harmful medications where possible.

The relationship between in-hospital location and outcomes of care in patients diagnosed with dementia and/or delirium diagnoses: analysis of patient journey

Background

The discrepancy between the number of admissions and the allocation of hospital beds means that many patients admitted to hospital can be placed in units or wards other than that which specialise in the patient’s primary health issue (home-ward). These patients are called ‘outlier’ patients. Risk factors and health system outcomes of hospital care for ‘outlier’ patients diagnosed with dementia and/or delirium are unknown. Therefore, the aim of this research was to examine patient journeys of people with dementia and/or delirium diagnoses, to identify risk factors for ‘inlier’ or ‘outlier’ status and patient or health system outcomes (consequences) of this status.

Methods

A retrospective, descriptive study compared patients who had dementia and/or delirium according to the proportion of time spent on the home ward i.e. ‘inliers’ or ‘outliers’. Data from the patient journey database at Flinders Medical Centre (FMC), a public hospital in South Australia from 2007 and 2014 were extracted and analysed. The analysis was carried out on the patient journeys of people with a dementia and/or delirium diagnosis.

Results

When 6367 inpatient journeys with dementia and/or delirium within FMC were examined, the Emergency Department (ED) Length of Stay (LOS) after being admitted as inpatient was prolonged for ‘outlier’ patients compared to ‘inlier’ patients (OR: 1.068, 95% CI: 1.057–1.079, p = 0.000). However, the inpatient LOS for’outlier’ patients was only marginally shorter than that of the ‘inlier’ patients (OR: 0.998, 95% CI: 0.998–0.998, p = 0.000). The chances of dying within 48 h of admission increased for ‘outlier’ patients (OR: 1.973, 95% CI: 1.158–3.359, p = 0.012) and their Charlson co-morbidity Index was higher (OR: 1.059, 95% CI: 1.021–1.10, p = 0.002). Completion of discharge summaries within 2 days post-discharge for ‘outlier’ patients was compromised (OR: 1.754, 95% CI: 1.492–2.061, p = 0.000).Additionally, ‘outlier’ patients were more likely to be discharged to another hospital for other care types not offered at FMC (OR: 1.931, 95% CI: 1.559–2.391, p = 0.000).

Conclusion

An examination of the patient journeys at FMC has determined that the health system outcomes for patients with dementia and/or delirium who are admitted outside of their home-ward are affected by in-hospital location despite the homogenous nature of the study population.

'Massive potential' or 'safety risk'? Health worker views on telehealth in the care of older people and implications for successful normalization

BACKGROUND

Telehealth technologies, which enable delivery of healthcare services at distance, offer promise for responding to the challenges created by an ageing population. However, successful implementation of telehealth into mainstream healthcare systems has been slow and fraught with failure. Understanding of frontline providers' experiences and attitudes regarding telehealth is a crucial aspect of successful implementation. This study aims to examine healthcare worker views on telehealth, and their implications for implementation to mainstream healthcare services for older people. The study includes a focus on two further dimensions of urban versus rural services and level of clinician experience with telehealth.

METHODS

Seven semi-structured focus groups were conducted with a total of 44 healthcare workers providing services to older people in the areas of rehabilitation and allied health, residential aged care and palliative care. Focus groups included both telehealth experienced and inexperienced groups. Of the experienced groups, two provided services to both urban and rural patients, and two to rural patients. Inexperienced groups included one rural and two urban. Thematic analysis was undertaken to identify predominant themes. Between-group differences and agreement in viewpoints for each of these themes are discussed and mapped to the theoretical constructs of Normalization Process Theory.

RESULTS

The views of participants varied with the extent of telehealth experience and perception of accessibility of healthcare services. Four themes describing clinician attitudes and perceptions that could impact on successful implementation of telehealth services are outlined: 1) Workability of telehealth: exponential growth in access or decay in the quality of healthcare? 2) What is an acceptable level of risk to patient safety with telehealth? 3) Shifting responsibilities and recalibrating the team; and 4) Change of architecture required to enable integration of telehealth service delivery.

CONCLUSIONS

The use of telehealth technologies to provide healthcare services to older people may be more readily normalized in areas where existing services are limited. Though exposure to telehealth may be a factor, changes to the perceived feasibility of telehealth in relation to conventional services, as well as supportive infrastructure and training and skill recalibration may be more critical to successful normalization of telehealth services for older people.

Evidence-based occupational therapy for people with dementia and their families: What clinical practice guidelines tell us and implications for practice

BACKGROUND/AIM

The first evidence-based Clinical Practice Guidelines and Principles of Care for People with Dementia in Australia have been released. The Guidelines detail a number of important evidence-based recommendations for occupational therapists. The aim of this paper is (1) to provide an overview of Guideline development, and (2) to describe the evidence supporting a recommendation for occupational therapy. Common characteristics of effective occupational therapy programmes for people with dementia are described.

METHODS

Guideline development involved adaptation of existing high-quality guidelines developed overseas and 17 systematic reviews to ensure that the most recent high-quality evidence was included. One of the systematic reviews involved examining the evidence for interventions to promote independence in people with dementia. Specifically, we looked at the evidence for occupational therapy and its effect on activities of daily living, quality of life and carer impact.

RESULTS

A total of 109 recommendations are included in the Guidelines. Occupational therapy was found to significantly increase independence in activities of daily living and improve quality of life. Effective occupational therapy programmes involve: environmental assessment, problem solving strategies, carer education and interactive carer skills training.

CONCLUSION

Occupational therapists working with people with dementia in community settings should ensure that their time is spent on those aspects of intervention that are shown to be effective.

Stroke Epidemiology in an Australian Rural Cohort (SEARCH)

Background Stroke rates in Australia and New Zealand have been declining since 1990 but all studies have been completed in large urban centers. Aim We report the first Australasian stroke incidence study in a rural population. Methods The authors applied the principle of complete ascertainment, used the WHO standard definition of stroke and classified ischemic stroke by the TOAST criteria. Data were collected from five rural centers defined by postcode of residence, over a 2-year period with 12 months of follow up of all cases. Results There were 217 strokes in 215 individuals in a population of 96,036 people, over 2 years, giving a crude attack rate of 113 per 100,000 per year. The 181 first-ever strokes (83% of total), standardized to the WHO world population, occurred at a rate of 50/100,000 (95% CI: 43-58). The 28-day fatality for first-ever strokes was 24% (95% CI: 18-31) and 77% (95% CI: 71-83) were classified as ischemic (140/181), 15% (95% CI: 10-21) intracerebral hemorrhage, 3% (95% CI: 1-6) due to subarachnoid hemorrhage and 5% (95% CI: 2-9) were unknown. A high proportion of first-ever ischemic strokes (44%) were cardioembolic, mostly (77%) due to atrial arrhythmias. Of the 38 with known atrial arrhythmias prior to stroke, only six (16%) were therapeutically anticoagulated. Conclusions This rural companion study of a recent Australian urban stroke incidence study confirms the downward trend of stroke incidence in Australia, and reiterates that inadequate anticoagulation of atrial arrhythmia remains a preventable cause of ischemic stroke.

A critical review of the long-term disability outcomes following hip fracture

BACKGROUND

Hip fractures are an increasingly common consequence of falls in older people that are associated with a high risk of death and reduced function. This review aims to quantify the impact of hip fracture on older people's abilities and quality of life over the long term.

METHODS

Studies were identified through PubMed and Scopus searches and contact with experts. Cohort studies of hip fracture patients reporting outcomes 3 months post-fracture or longer were included for review. Outcomes of mobility, participation in domestic and community activities, health, accommodation or quality of life were categorised according to the World Health Organization's International Classification of Functioning and synthesised narratively. Risk of bias was assessed according to four items from the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement.

RESULTS

Thirty-eight studies from 42 publications were included for review. Most followed a clearly defined sample from the time of fracture. Hip fracture survivors experienced significantly worse mobility, independence in function, health, quality of life and higher rates of institutionalisation than age matched controls. The bulk of recovery of walking ability and activities for daily living occurred within 6 months after fracture. Between 40 and 60 % of study participants recovered their pre-fracture level of mobility and ability to perform instrumental activities of daily living, while 40-70 % regained their level of independence for basic activities of daily living. For people independent in self-care pre-fracture, 20-60 % required assistance for various tasks 1 and 2 years after fracture. Fewer people living in residential care recovered their level of function than those living in the community. In Western nations, 10-20 % of hip fracture patients are institutionalised following fracture. Few studies reported impact on participation in domestic, community, social and civic life.

CONCLUSIONS

Hip fracture has a substantial impact on older peoples' medium- to longer-term abilities, function, quality of life and accommodation. These studies indicate the range of current outcomes rather than potential improvements with different interventional approaches. Future studies should measure impact on life participation and determine the proportion of people that regain their pre-fracture level of functioning to investigate strategies for improving these important outcomes.

Anabolic steroids for rehabilitation after hip fracture in older people

BACKGROUND:

Hip fracture occurs predominantly in older people, many of whom are frail and undernourished. After hip fracture surgery and rehabilitation, most patients experience a decline in mobility and function. Anabolic steroids, the synthetic derivatives of the male hormone testosterone, have been used in combination with exercise to improve muscle mass and strength in athletes. They may have similar effects in older people who are recovering from hip fracture.

OBJECTIVES:

To examine the effects (primarily in terms of functional outcome and adverse events) of anabolic steroids after surgical treatment of hip fracture in older people.

METHODS:

Search methods: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialized Register (10 September 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2013 Issue 8), MEDLINE (1946 to August Week 4 2013), EMBASE (1974 to 2013 Week 36), trial registers, conference proceedings, and reference lists of relevant articles. The search was run in September 2013.Selection criteria: Randomized controlled trials of anabolic steroids given after hip fracture surgery, in inpatient or outpatient settings, to improve physical functioning in older patients with hip fracture.Data collection and analysis: Two review authors independently selected trials (based on predefined inclusion criteria), extracted data and assessed each study's risk of bias. A third review author moderated disagreements. Only very limited pooling of data was possible. The primary outcomes were function (for example, independence in mobility and activities of daily living) and adverse events, including mortality.

MAIN RESULTS:

We screened 1290 records and found only three trials involving 154 female participants, all of whom were aged above 65 years and had had hip fracture surgery. All studies had methodological shortcomings that placed them at high or unclear risk of bias. Because of this high risk of bias, imprecise results and likelihood of publication bias, we judged the quality of the evidence for all primary outcomes to be very low.These trials tested two comparisons. One trial had three groups and contributed data to both comparisons. None of the trials reported on patient acceptability of the intervention.Two very different trials compared anabolic steroid versus control (no anabolic steroid or placebo). One trial compared anabolic steroid injections (given weekly until discharge from hospital or four weeks, whichever came first) versus placebo injections in 29 "frail elderly females". This found very low quality evidence of little difference between the two groups in the numbers discharged to a higher level of care or dead (one person in the control group died) (8/15 versus 10/14; risk ratio (RR) 0.75, 95% confidence interval (CI) 0.42 to 1.33; P = 0.32), time to independent mobilization or individual adverse events. The second trial compared anabolic steroid injections (every three weeks for six months) and daily protein supplementation versus daily protein supplementation alone in 40 "lean elderly women" who were followed up for one year after surgery. This trial provided very low quality evidence that anabolic steroid may result in less dependency, assessed in terms of being either dependent in at least two functions or dead (one person in the control group died) at six and 12 months, but the result was also compatible with no difference or an increase in dependency (dependent in at least two levels of function or dead at 12 months: 1/17 versus 5/19; RR 0.22, 95% CI 0.03 to 1.73; P = 0.15). The trial found no evidence of between-group differences in individual adverse events.Two trials compared anabolic steroids combined with another nutritional intervention ('steroid plus') versus control (no 'steroid plus'). One trial compared anabolic steroid injections every three weeks for 12 months in combination with daily supplement of vitamin D and calcium versus calcium only in 63 women who were living independently at home. The other trial compared anabolic steroid injections every three weeks for six months and daily protein supplementation versus control in 40 "lean elderly women". Both trials found some evidence of better function in the steroid plus group. One trial reported greater independence, higher Harris hip scores and gait speeds in the steroid plus group at 12 months. The second trial found fewer participants in the anabolic steroid group were either dependent in at least two functions, including bathing, or dead at six and 12 months (one person in the control group died) (1/17 versus 7/18; RR 0.15, 95% CI 0.02 to 1.10; P = 0.06). Pooled mortality data (2/51 versus 3/51) from the two trials showed no evidence of a difference between the two groups at one year. Similarly, there was no evidence of between-group differences in individual adverse events. Three participants in the steroid group of one trial reported side effects of hoarseness and increased facial hair. The other trial reported better quality of life in the steroid plus group.

AUTHORS' CONCLUSIONS:

The available evidence is insufficient to draw conclusions on the effects, primarily in terms of functional outcome and adverse events, of anabolic steroids, either separately or in combination with nutritional supplements, after surgical treatment of hip fracture in older people. Given that the available data points to the potential for more promising outcomes with a combined anabolic steroid and nutritional supplement intervention, we suggest that future research should focus on evaluating this combination.

A Systematic Review and Meta-Analysis Comparing Carer Focused and Dyadic Multicomponent Interventions for Carers of People With Dementia

Objective: The aim of this study was to compare the efficacy of two approaches: multicomponent interventions that focus on working with the carer and dyadic interventions that work with both the carer and the person with dementia. Method: A systematic review involving a search of Medline, EMBASE, and PsycINFO in October 2015 was performed. Randomized controlled trials involving carers of people with dementia and comparing multicomponent interventions with usual care were included. Results: Pooling of all studies demonstrated that multicomponent interventions can reduce depressive symptoms, improve quality of life, reduce carer impact, and reduce behavioral and psychological symptoms of dementia as well as caregiver upset with these symptoms. We were unable to find a significant difference in the effects of dyadic interventions in comparison with carer focused interventions for these outcomes. Discussion: Although effect sizes associated with intervention are small, multicomponent interventions are relatively inexpensive to deliver, acceptable, and widely applicable.

Investigating the preferences of older people for telehealth as a new model of health care service delivery: A discrete choice experiment

Introduction Telehealth approaches to health care delivery can potentially improve quality of care and clinical outcomes, reduce mortality and hospital utilisation, and complement conventional treatments. However, substantial research into the potential for integrating telehealth within health care in Australia, particularly in the provision of services relevant to older people, including palliative care, aged care and rehabilitation, is lacking. Furthermore, to date, no discrete choice experiment (DCE) studies internationally have sought the views and preferences of older people about the basic features that should make up a telehealth approach to these services. Methods Using a DCE, we investigated the relative importance of six salient features of telehealth (what aspects of care are to be pursued during telehealth sessions, distance to the nearest hospital or clinic, clinicians' attitude to telehealth, patients' experience of using technology, what types of assessments should be conducted face-to-face versus via telehealth sessions and the costs associated with receiving telehealth). Data were obtained from an online panel of older people aged 65 years and above, drawn from the Australian general population. Results The mean age for 330 study participants was 69 years. In general, individuals expressed strong preferences for telehealth services that offered all aspects of care, were relatively inexpensive and targeted specifically at individuals living in remote regions without easy access to a hospital or clinic. Participants also preferred telehealth services to be offered to individuals with some prior experience of using technology, provided by clinicians who were positive about telehealth but wanted all or some pre-telehealth health assessments to take place in a hospital or clinic. Preferences only differed by gender. Additionally, respondents did not feel that telehealth led to loss of privacy and confidentiality. Discussion Our findings indicate a preference amongst respondents for face-to-face pre-telehealth health assessments and, thereafter, a comprehensive telehealth model (in terms of services offered) targeted at those with some technological know-how as a substitute for attendance at hospitals and clinics, especially where these health facilities were far away from older people's homes. The findings may be usefully incorporated into the design of future telehealth models of service delivery for older people.

Development of the Adelaide Driving Self-Efficacy Scale

Objective: To describe the development of the Adelaide Driving Self-Efficacy Scale (ADSES) and to report on its reliability and validity.

Methods: A set of 12 driving behaviours, developed through literature review, clinical experience and expert review, were rated for self-efficacy using a Likert scale. Internal consistency was investigated using a Cronbach's alpha coefficient and construct validity by comparing ADSES scores of stroke and non-stroke drivers. Criterion-related validity was examined by comparing ADSES scores with the result on a standardized on-road assessment.

Setting: A rehabilitation hospital in Adelaide, South Australia.

Participants: Staff from the hospital and stroke patients from the rehabilitation unit. Data from a non-stroke sample (n -/ 79) and stroke patients (n -/ 81) were used to test internal consistency and construct validity. A separate group of 45 people recommended for a driving assessment, of whom 34 were stroke patients, were used to test criterion validity.

Results: Cronbach's alpha coefficient was 0.98, indicating high internal consistency. The non-stroke and stroke groups showed significant differences in ADSES scores (t(158)-/ 5.5, P B < 0.05), demonstrating construct validity. Differences in ADSES scores for those participants who passed or failed the on-road assessment were significant for both the entire driving assessment group (t(43)-/ 3.2, P B < 0.05) and the stroke subgroup (t(43)-/ 3.2, P B < 0.05), indicating criterion validity.

Conclusion: The ADSES has demonstrated internal consistency and construct validity with the stroke and non-stroke population. The scale demonstrated criterion validity in its relationship with outcome of an on-road driving assessment. It appears to be a reliable and valid measure of driving self-efficacy.

Falls in community-dwelling older persons following hip fracture: impact on self-efficacy, balance and handicap

Objective: To compare the four-month outcomes of fallers and nonfallers as well as those with slow gait speed in patients with hip fracture successfully discharged back to the community.

Design: Prospective study with four-month follow-up data.

Setting: Community sample of survivors of hip fracture who have completed their rehabilitation programme.

Subjects: A consecutive sample of 73 community-dwelling, cognitively intact older adults admitted to hospital following a fall-related hip fracture and available to complete a follow-up assessment at four months.

Main outcome measures: At baseline, data collection consisted of the Modified Barthel Index (MBI), Mini Mental State Examination (MMSE), sociodemographics and medical history. At four months follow-up, data collection consisted of the MBI, London Handicap Scale (LHS), Berg Balance Scale (BBS), a 10-metre timed walk test, Falls Efficacy Scale (FES) and the Activities Balance Confidence (ABC) scale. Participants were also asked to recall if they had fallen in the four months since their fracture.

Results: Seventy-three participants had complete data for evaluation. There was minimal disability with a mean MBI of 91.2 but there was some residual handicap with a mean LHS of 0.67. Those who had fallen had lower selfefficacy (FES) and greater handicap (LHS). Those with slower gait speed were more handicapped (LHS), had lower self-efficacy (FES and ABC) and lower balance scores (BBS).

Conclusions: Measuring ADL disability alone loses valuable information in community-dwelling survivors of hip fracture. Falls after hip fracture should be a target for treatment and our data give some weight to the idea of a fall fracture cycle. Gait speed, which may re‘ect lower limb strength, is also a target for therapeutic interventions. These measures should be included in clinical practice.

Attitudes to falls and injury prevention: what are the barriers to implementing falls prevention strategies?

Objectives: To ascertain the reasons for not taking up a fall or injury prevention strategy among older people who have sustained a fall and attended an emergency department.

Subjects: As part of another trial, we identified 60 people who attended the emergency department of a public hospital with a fall.

Main measures: Participants were interviewed to ascertain the reasons for not taking up a falls prevention strategy, their falls-related health state, and the likelihood of them undertaking a falls and injury prevention strategy.

Results: A total of 31 (52%) of the participants had considered falls prevention after their fall. There were high levels of reluctance to undertake a strategy with 43 (72%) reluctant to take exercise classes, 10 (59%) reluctant to cease psychotropic medications, 26 (43%) reluctant to have a home safety assessment and 17 (28%) reluctant to take osteoporotic medication. When asked specifically about taking up a strategy to prevent a worsening health state, 19 (63%) of participants would take up exercise, 17 (57%) a home safety assessment, 4 of the 17 (59%) already taking implicated medications would stop and 56 (93%) would begin osteoporotic medication. These decisions did not alter when the goal for treatment was to improve a much worse health state. In participants with a lower starting health state, home safety assessments were viewed more favourably.

Conclusions: There were significant obstacles to the implementation of most falls prevention guidelines examined. Treatment for osteoporosis was more acceptable to participants than exercise classes, cessation of psychotropic medication, and having a home safety assessment. Osteoporosis treatment, which had the least resistance, also had the least impact on the participants' lifestyle.

Additional weekend therapy may reduce length of rehabilitation stay after stroke: a meta-analysis of individual patient data

QUESTIONS

Among people receiving inpatient rehabilitation after stroke, does additional weekend physiotherapy and/or occupational therapy reduce the length of rehabilitation hospital stay compared to those who receive a weekday-only service, and does this change after controlling for individual factors? Does additional weekend therapy improve the ability to walk and perform activities of daily living, measured at discharge? Does additional weekend therapy improve health-related quality of life, measured 6 months after discharge from rehabilitation? Which individual, clinical and hospital characteristics are associated with shorter length of rehabilitation hospital stay?

DESIGN

This study pooled individual data from two randomised, controlled trials (n=350) using an individual patient data meta-analysis and multivariate regression.

PARTICIPANTS

People with stroke admitted to inpatient rehabilitation facilities.

INTERVENTION

Additional weekend therapy (physiotherapy and/or occupational therapy) compared to usual care (5 days/week therapy).

OUTCOME MEASURES

Length of rehabilitation hospital stay, independence in activities of daily living measured with the Functional Independence Measure, walking speed and health-related quality of life.

RESULTS

Participants who received weekend therapy had a shorter length of rehabilitation hospital stay. In the un-adjusted analysis, this was not statistically significant (MD -5.7 days, 95% CI -13.0 to 1.5). Controlling for hospital site, age, walking speed and Functional Independence Measure score on admission, receiving weekend therapy was significantly associated with a shorter length of rehabilitation hospital stay (β=7.5, 95% CI 1.7 to 13.4, p=0.001). There were no significant between-group differences in Functional Independence Measure scores (MD 1.9 points, 95% CI -2.8 to 6.6), walking speed (MD 0.06 m/second, 95% CI -0.15 to 0.04) or health-related quality of life (SMD -0.04, 95% CI -0.26 to 0.19) at discharge.

DISCUSSION

Modest evidence indicates that additional weekend therapy might reduce rehabilitation hospital length of stay.

Early Supported Discharge by Caregiver-Mediated Exercises and e-Health Support After Stroke: A Proof-of-Concept Trial

BACKGROUND AND PURPOSE

This proof-of-concept trial investigated the effects of an 8-week program of caregiver-mediated exercises commenced in hospital combined with tele-rehabilitation services on patient self-reported mobility and caregiver burden.

METHODS

Sixty-three hospitalized stroke patients (mean age 68.7, 64% female) were randomly allocated to an 8-week caregiver-mediated exercises program with e-health support or usual care. Primary outcome was the Stroke Impact Scale mobility domain. Secondary outcomes included length of stay, other Stroke Impact Scale domains, readmissions, motor impairment, strength, walking ability, balance, mobility, (extended) activities of daily living, psychosocial functioning, self-efficacy, quality of life, and fatigue. Additionally, caregiver's self-reported fatigue, symptoms of anxiety, self-efficacy, and strain were assessed. Assessments were completed at baseline and at 8 and 12 weeks.

RESULTS

Intention-to-treat analysis showed no between-group difference in Stroke Impact Scale mobility (P=0.6); however, carers reported less fatigue (4.6, confidence interval [CI] 95% 0.3-8.8; P=0.04) and higher self-efficacy (-3.3, CI 95% -5.7 to -0.9; P=0.01) at week 12. Per-protocol analysis, examining those who were discharged home with tele-rehabilitation demonstrated a trend toward improved mobility (-9.8, CI 95% -20.1 to 0.4; P=0.06), significantly improved extended activities of daily living scores at week 8 (-3.6, CI 95% -6.3 to -0.8; P=0.01) and week 12 (3.0, CI 95% -5.8 to -0.3; P=0.03), a 9-day shorter length of stay (P=0.046), and fewer readmissions over 12 months (P<0.05).

CONCLUSIONS

Caregiver-mediated exercises supported by tele-rehabilitation show promise to augment intensity of practice, resulting in improved patient-extended activities of daily living, reduced length of stay with fewer readmissions post stroke, and reduced levels of caregiver fatigue with increased feelings of self-efficacy. The current findings justify a larger definite phase III randomized controlled trial.

Effect of affordable technology on physical activity levels and mobility outcomes in rehabilitation: a protocol for the Activity and MObility UsiNg Technology (AMOUNT) rehabilitation trial

INTRODUCTION

People with mobility limitations can benefit from rehabilitation programmes that provide a high dose of exercise. However, since providing a high dose of exercise is logistically challenging and resource-intensive, people in rehabilitation spend most of the day inactive. This trial aims to evaluate the effect of the addition of affordable technology to usual care on physical activity and mobility in people with mobility limitations admitted to inpatient aged and neurological rehabilitation units compared to usual care alone.

METHODS AND ANALYSIS

A pragmatic, assessor blinded, parallel-group randomised trial recruiting 300 consenting rehabilitation patients with reduced mobility will be conducted. Participants will be individually randomised to intervention or control groups. The intervention group will receive technology-based exercise to target mobility and physical activity problems for 6 months. The technology will include the use of video and computer games/exercises and tablet applications as well as activity monitors. The control group will not receive any additional intervention and both groups will receive usual inpatient and outpatient rehabilitation care over the 6-month study period. The coprimary outcomes will be objectively assessed physical activity (proportion of the day spent upright) and mobility (Short Physical Performance Battery) at 6 months after randomisation. Secondary outcomes will include: self-reported and objectively assessed physical activity, mobility, cognition, activity performance and participation, utility-based quality of life, balance confidence, technology self-efficacy, falls and service utilisation. Linear models will assess the effect of group allocation for each continuously scored outcome measure with baseline scores entered as a covariate. Fall rates between groups will be compared using negative binomial regression. Primary analyses will be preplanned, conducted while masked to group allocation and use an intention-to-treat approach.

ETHICS AND DISSEMINATION

The protocol has been approved by the relevant Human Research Ethics Committees and the results will be disseminated widely through peer-reviewed publication and conference presentations.

Interventions to delay functional decline in people with dementia: a systematic review of systematic reviews

OBJECTIVE

To summarise existing systematic reviews that assess the effects of non-pharmacological, pharmacological and alternative therapies on activities of daily living (ADL) function in people with dementia.

DESIGN

Overview of systematic reviews.

METHODS

A systematic search in the Cochrane Database of Systematic Reviews, DARE, Medline, EMBASE and PsycInfo in April 2015. Systematic reviews of randomised controlled trials conducted in people with Alzheimer's disease or dementia measuring the impact on ADL function were included. Methodological quality of the systematic reviews was independently assessed by two authors using the AMSTAR tool. The quality of evidence of the primary studies for each intervention was assessed using GRADE.

RESULTS

A total of 23 systematic reviews were included in the overview. The quality of the reviews varied; however most (65%) scored 8/11 or more on the AMSTAR tool, indicating high quality. Interventions that were reported to be effective in minimising decline in ADL function were: exercise (6 studies, 289 participants, standardised mean difference (SMD) 0.68, 95% CI 0.08 to 1.27; GRADE: low), dyadic interventions (8 studies, 988 participants, SMD 0.37, 95% CI 0.05 to 0.69; GRADE: low) acetylcholinesterase inhibitors and memantine (12 studies, 4661 participants, donepezil 10 mg SMD 0.18, 95% CI 0.03 to 0.32; GRADE: moderate), selegiline (7 studies, 810 participants, SMD 0.27, 95% CI 0.13 to 0.41; GRADE: low), huperzine A (2 studies, 70 participants, SMD 1.48, 95% CI 0.95 to 2.02; GRADE: very low) and Ginkgo biloba (7 studies, 2530 participants, SMD 0.36, 95% CI 0.28 to 0.44; GRADE: very low).

CONCLUSIONS

Healthcare professionals should ensure that people with dementia are encouraged to exercise and that primary carers are trained and supported to provide safe and effective care for the person with dementia. Acetylcholinesterase inhibitors or memantine should be trialled unless contraindicated.

Orthotic and therapeutic effect of functional electrical stimulation on fatigue induced gait patterns in people with multiple sclerosis

PURPOSE

To assess the orthotic and therapeutic effects of prolonged use of functional electrical stimulation (FES) on fatigue induced gait patterns in people with Multiple Sclerosis (MS).

METHOD

Thirteen people with MS completed 3D gait analysis with FES off and on, before and after a fatiguing 6-minute walk, at baseline and after 8 weeks of use of FES.

RESULTS

Eleven participants completed all testing. An orthotic effect on gait was not evident on first use of FES. However, therapeutic effects on gait after 8 weeks use were generally positive, including increases in walking speed due to improved neuromuscular control and power generated at the hip and ankle of the more affected limb. The action of FES alone was not sufficient to overcome all fatigue related deficits in gait but there was evidence 8 weeks use of FES can ameliorate some fatigue effects on lower limb kinetics, including benefits to ankle mechanics involved in generating power around push-off during stance.

CONCLUSIONS

Eight-weeks of FES can benefit the gait pattern of people with MS under non-fatigued and fatigued conditions. Implications for rehabilitation In some people with MS prolonged use of FES may be necessary before observing positive orthotic effects. Improvements in the neuromuscular control of the more affected lower limb may develop with prolonged use of FES in people with MS. Only some therapeutic benefits of FES are maintained during fatigued walking in people with MS. FES may be considered as a gait retraining device as well as an orthotic intervention for people with MS.
