Effectiveness of knowledge brokering and recommendation dissemination for influencing healthcare resource allocation decisions: A cluster randomised controlled implementation trial.

BACKGROUND: Implementing evidence into clinical practice is a key focus of healthcare improvements to reduce unwarranted variation. Dissemination of evidence-based recommendations and knowledge brokering have emerged as potential strategies to achieve evidence implementation by influencing resource allocation decisions. The aim of this study was to determine the effectiveness of these two research implementation strategies to facilitate evidence-informed healthcare management decisions for the provision of inpatient weekend allied health services. METHODS AND FINDINGS: This multicentre, single-blinded (data collection and analysis), three-group parallel cluster randomised controlled trial with concealed allocation was conducted in Australian and New Zealand hospitals between February 2018 and January 2020. Clustering and randomisation took place at the organisation level where weekend allied health staffing decisions were made (e.g., network of hospitals or single hospital). Hospital wards were nested within these decision-making structures. Three conditions were compared over a 12-month period: (1) usual practice waitlist control; (2) dissemination of written evidence-based practice recommendations; and (3) access to a webinar-based knowledge broker in addition to the recommendations. The primary outcome was the alignment of weekend allied health provision with practice recommendations at the cluster and ward levels, addressing the adoption, penetration, and fidelity to the recommendations. The secondary outcome was mean hospital length of stay at the ward level. Outcomes were collected at baseline and 12 months later. A total of 45 clusters (n = 833 wards) were randomised to either control (n = 15), recommendation (n = 16), or knowledge broker (n = 14) conditions. Four (9%) did not provide follow-up data, and no adverse events were recorded. No significant effect was found with either implementation strategy for the primary outcome at the cluster level (recommendation versus control ß 18.11 [95% CI -8,721.81 to 8,758.02] p = 0.997; knowledge broker versus control ß 1.24 [95% CI -6,992.60 to 6,995.07] p = 1.000; recommendation versus knowledge broker ß -9.12 [95% CI -3,878.39 to 3,860.16] p = 0.996) or ward level (recommendation versus control ß 0.01 [95% CI 0.74 to 0.75] p = 0.983; knowledge broker versus control ß -0.12 [95% CI -0.54 to 0.30] p = 0.581; recommendation versus knowledge broker ß -0.19 [-1.04 to 0.65] p = 0.651). There was no significant effect between strategies for the secondary outcome at ward level (recommendation versus control ß 2.19 [95% CI -1.36 to 5.74] p = 0.219; knowledge broker versus control ß -0.55 [95% CI -1.16 to 0.06] p = 0.075; recommendation versus knowledge broker ß -3.75 [95% CI -8.33 to 0.82] p = 0.102). None of the control or knowledge broker clusters transitioned to partial or full alignment with the recommendations. Three (20%) of the clusters who only received the written recommendations transitioned from nonalignment to partial alignment. Limitations include underpowering at the cluster level sample due to the grouping of multiple geographically distinct hospitals to avoid contamination. CONCLUSIONS: Owing to a lack of power at the cluster level, this trial was unable to identify a difference between the knowledge broker strategy and dissemination of recommendations compared with usual practice for the promotion of evidence-informed resource allocation to inpatient weekend allied health services. Future research is needed to determine the interactions between different implementation strategies and healthcare contexts when translating evidence into healthcare practice.

Self-managed occupational therapy and physiotherapy for adults receiving inpatient rehabilitation ('My Therapy'): protocol for a stepped-wedge cluster randomised trial.

BACKGROUND: Ensuring patients receive an effective dose of therapeutic exercises and activities is a significant challenge for inpatient rehabilitation. My Therapy is a self-management program which encourages independent practice of occupational therapy and physiotherapy exercises and activities, outside of supervised therapy sessions. METHODS: This implementation trial aims to determine both the clinical effectiveness of My Therapy on the outcomes of function and health-related quality of life, and cost-effectiveness per minimal clinically important difference (MCID) in functional independence achieved and per quality adjusted life year (QALY) gained, compared to usual care. Using a stepped-wedge cluster randomised design, My Therapy will be implemented across eight rehabilitation wards (inpatient and home-based) within two public and two private Australian health networks, over 54-weeks. We will include 2,160 patients aged 18 + years receiving rehabilitation for any diagnosis. Each ward will transition from the usual care condition (control group receiving usual care) to the experimental condition (intervention group receiving My Therapy in addition to usual care) sequentially at six-week intervals. The primary clinical outcome is achievement of a MCID in the Functional Independence Measure (FIM™) at discharge. Secondary outcomes include improvement in quality of life (EQ-5D-5L) at discharge, length of stay, 30-day re-admissions, discharge accommodation, follow-up rehabilitation services and adverse events (falls). The economic outcomes are the cost-effectiveness per MCID in functional independence (FIM™) achieved and per QALY gained, for My Therapy compared to usual care, from a health-care sector perspective. Cost of implementation will also be reported. Clinical outcomes will be analysed via mixed-effects linear or logistic regression models, and economic outcomes will be analysed via incremental cost-effectiveness ratios. DISCUSSION: The My Therapy implementation trial will determine the effect of adding self-management within inpatient rehabilitation care. The results may influence health service models of rehabilitation including recommendations for systemic change to the inpatient rehabilitation model of care to include self-management. Findings have the potential to improve patient function and quality of life, and the ability to participate in self-management. Potential health service benefits include reduced hospital length of stay, improved access to rehabilitation and reduced health service costs. TRIAL REGISTRATION: This study was prospectively registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12621000313831; registered 22/03/2021, http://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=380828&isReview=true ).

Divesting from a Scored Hospital Fall Risk Assessment Tool (FRAT): A Cluster Randomized Non-Inferiority Trial.

BACKGROUND/OBJECTIVES: We investigated the impact of ceasing routine falls risk assessment tool (FRAT) completion and instead used clinical reasoning to select fall mitigation strategies. DESIGN: Two-group, multi-site cluster-randomized active-control non-inferiority trial. SETTING: Hospital wards. PARTICIPANTS: Adult inpatients admitted to participating hospitals (n = 10 hospitals, 123,176 bed days). INTERVENTION: Hospitals were randomly assigned (1:1) to a usual care control group that continued to use a historical FRAT to assign falls risk scores and accompanying mitigation strategies, or an experimental group whereby clinicians did not assign risk scores and instead used clinical reasoning to select fall mitigation strategies using a decision support list. MEASUREMENTS: The primary measure was between-group difference in mean fall rates (falls/1000 bed days). Falls were identified from incident reports supplemented by hand searches of medical records over three consecutive months at each hospital. The incidence rate ratio (IRR) of monthly falls rates in control versus experimental hospitals was also estimated. RESULTS: The experimental clinical reasoning approach was non-inferior to the usual care FRAT that assigned fall risk ratings when compared to a-priori stakeholder derived and sensitivity non-inferiority margins. The mean fall rates were 3.84 falls/1000 bed days for the FRAT continuing sites and 3.11 falls/1000 bed days for experimental sites. After adjusting for historical fall rates at each hospital, the IRR (95%CI) was 0.78 (0.64, 0.95), where IRR < 1.00 indicated fewer falls among the experimental group. There were 4 and 3 serious events in the control and experimental groups, respectively. CONCLUSION: Replacing a FRAT scoring system with clinical reasoning did not lead to inferior fall outcomes in the short term and may even reduce fall incidence.

Hand dexterity assessment in Parkinson's disease: construct validity of the 9-Hole peg test for the more affected hand.

PURPOSE: There is limited understanding of the characteristics and evaluation of more affected hand dexterity loss in Parkinson's disease. We described 9-Hole Peg Test performance for the more affected hand and examined the construct validity of these pegboard scores in mild to severe Parkinson's disease. Methods: This observational study analysed baseline data from a cluster-randomised controlled trial.Participants (n = 582) completed the pegboard with their more affected hand, the Patient-Specific Index-Parkinson's Disease and Self-assessment Parkinson's Disease Disability Scale. Mean pegboard performance was summarised at each disease stage. To investigate known groups validity, we explored differences in pegboard scores between participants identifying upper limb problems in their 'top three' functional limitations, and those prioritising other limitations. Convergent validity investigated correlations between pegboard performance and self-reported hand function. RESULTS: Pegboard performance was reduced compared with normative values, and problems with hand activities were reported at each disease stage. Significant differences in pegboard performance between the two functional limitation priority groups (p < 0.05), and moderate correlations between pegboard dexterity and hand function (Self-assessment Parkinson's Disease Disability Scale) provided evidence for construct validity. CONCLUSIONS: People with mild to severely disabling Parkinson's disease have reduced dexterity and problems with hand function. Evidence supported the construct validity of 9-Hole Peg Test more affected hand performance.IMPLICATIONS FOR REHABILITATIONPeople with mild to severely disabling PD experience dexterity loss and problems with hand function.It is important for clinicians to assess dexterity and hand function in people with this movement disorder.Evidence supports the construct validity of 9-Hole Peg Test for measuring more affected hand performance in Parkinson's disease.

How do health professionals prioritize clinical areas for implementation of evidence into practice? A cross-sectional qualitative study.

AIM: The current study aimed to identify and understand the reasons why allied health professionals think certain areas of healthcare service provision are a high priority for implementation of evidence into practice. METHODS: A cross-sectional online survey using open-ended questions was conducted between April and May 2018 to identify potential areas for practice change and characterize how participants justified identified areas of priority. Eligible participants were invited by email and included allied health professionals from public or private health services, governance agencies and universities across Australia. Responses were analysed using qualitative content analysis. RESULTS: There were 149 surveys commenced with 146 respondents completing the survey. Of the 146 respondents, 128 were female, 17 male and one unknown. Most of the respondents were between 40 and 49 years old and had a master's degree. In total respondents from more than 13 different professions completed the survey with 110 respondents having more than 10 years of experience in allied health. Ten themes emerged outlining the main reasons respondents felt that their nominated areas of practice change were a high priority for action. These included closing gaps between practice and policy/recommendation/guideline; closing research evidence to practice gaps; improving access to services; perceived cost-effectiveness of service delivery; improving effectiveness of allied health services; current imbalance between service supply and demand; amount of resources involved in service delivery; extent of the health problem; areas of allied health care futility; and equality of workload across allied health professionals. CONCLUSION: The current research provides insights into the decision-making processes of allied health professionals when prioritizing areas of clinical practice for implementation of evidence into practice. Despite an appetite for evidence-based practice, behaviour change was not always implemented in a consistent and systematic manner. There was variability in the type and application of evidence used by allied health professionals to support clinical practice. Whether a more systematic approach to research translation fosters evidence uptake awaits confirmation. Also awaiting investigation are the economic and societal impacts of consistently implementing research-informed clinical decision-making.

Perspectives of older adults regarding barriers and enablers to engaging in fall prevention activities after hospital discharge.

Older adults recently discharged from hospital are at high risk of functional decline and falls. A tailored fall prevention education provided at hospital discharge aimed to improve the capacity of older adults to engage in falls prevention activities. What remains unknown are the factors affecting behaviour change after hospital discharge. This study identified the perceived barriers and enablers of older adults to engagement in fall prevention activities during the 6-month period post-discharge. An exploratory approach using interpretative phenomenological analysis focused on the lived experience of a purposive sample (n = 30) of participants. All were recruited as a part of an RCT (n = 390) that delivered a tailored fall prevention education program at three hospital rehabilitation wards in Perth, Australia. Data were collected at 6-month post-discharge using semi-structured telephone surveys. Personal stories confirmed that some older adults have difficulty recovering functional ability after hospital discharge. Reduced physical capability, such as experiences of fatigue, chronic pain and feeling unsteady when walking were barriers for participants to safely return to their normal daily activities. Participants who received the tailored fall education program reported positive effects on knowledge and motivation to engage in fall prevention. Participants who had opportunities to access therapy or social supports described more positive experiences of recovery compared to individuals who persevered without assistance. A lack of physical and social support was associated with apprehension and fear toward adverse events such as falls, injuries, and hospital readmission. The lived experience of participants following hospital discharge strongly suggested that they required more supports from both healthcare professionals and caregivers to ensure that their needs were met. Further research that evaluates how to assist this population to engage in programs that will mitigate the high risk of falls and hospital readmissions is required.

A Randomized Trial to Increase the Assessment Accuracy of Glaucoma and Optic Disc Characteristics by Orthoptists.

INTRODUCTION: The aim of this study was to determine the accuracy of orthoptists when examining the optic disc for signs of glaucoma, and to explore the impact of targeted clinical education on accuracy. METHODS: In this randomized controlled trial, 42 monoscopic color optic disc images were presented to 46 orthoptists who assessed the likelihood of glaucoma as well as optic disc size, shape, tilting, vertical cup-to-disc ratio, cup shape, depth, presence of hemorrhage, peripapillary atrophy, and retinal nerve fiber layer. The level of agreement with specialist ophthalmologists was assessed. Participants were then randomly assigned to an experimental group (targeted postgraduate education on optic disc assessment) or to no intervention. The educational program was designed to increase knowledge of the characteristic features associated with glaucomatous optic neuropathy. All participants re-examined the included optic disc images after a period of 6 to 8 weeks. The primary outcome measure was a change in agreement between attempts. RESULTS: The education group showed significant improvements between attempts for identifying hemorrhages (P = .013), retinal nerve fiber layer defects (0.035), disc size (P = .001), peripapillary atrophy (P = .030), and glaucoma likelihood (P = .023). The control group did not show any statistically significant improvement. The intervention group showed significantly more improvement when identifying hemorrhages (P = .013), disc size (P = .001), disc shape (P = .033), and cup shape (P = .020) compared with the control group. DISCUSSION: Orthoptists who received additional postgraduate online education based on principles of adult learning were more accurate at assessing the optic disc for glaucoma. These results highlight the value of continuing education to optimize clinical practice in allied health professionals.

Implementation of evidence-based weekend service recommendations for allied health managers: a cluster randomised controlled trial protocol.

BACKGROUND: It is widely acknowledged that health policy and practice do not always reflect current research evidence. Whether knowledge transfer from research to practice is more successful when specific implementation approaches are used remains unclear. A model to assist engagement of allied health managers and clinicians with research implementation could involve disseminating evidence-based policy recommendations, along with the use of knowledge brokers. We developed such a model to aid decision-making for the provision of weekend allied health services. This protocol outlines the design and methods for a multi-centre cluster randomised controlled trial to evaluate the success of research implementation strategies to promote evidence-informed weekend allied health resource allocation decisions, especially in hospital managers. METHODS: This multi-centre study will be a three-group parallel cluster randomised controlled trial. Allied health managers from Australian and New Zealand hospitals will be randomised to receive either (1) an evidence-based policy recommendation document to guide weekend allied health resource allocation decisions, (2) the same policy recommendation document with support from a knowledge broker to help implement weekend allied health policy recommendations, or (3) a usual practice control group. The primary outcome will be alignment of weekend allied health service provision with policy recommendations. This will be measured by the number of allied health service events (occasions of service) occurring on weekends as a proportion of total allied health service events for the relevant hospital wards at baseline and 12-month follow-up. DISCUSSION: Evidence-based policy recommendation documents communicate key research findings in an accessible format. This comparatively low-cost research implementation strategy could be combined with using a knowledge broker to work collaboratively with decision-makers to promote knowledge transfer. The results will assist managers to make decisions on resource allocation, based on evidence. More generally, the findings will inform the development of an allied health model for translating research into practice. TRIAL REGISTRATION: This trial is registered with the Australian New Zealand Clinical Trials Registry (ANZCTR) ( ACTRN12618000029291 ). Universal Trial Number (UTN): U1111-1205-2621.

Cost of Living with Parkinson's Disease over 12 Months in Australia: A Prospective Cohort Study.

Background. Parkinson disease (PD) is a costly chronic condition in terms of managing both motor and nonmotor symptoms. The burden of disease is high for individuals, caregivers, and the health system. The aim of this study is to estimate the annual cost of PD from the household, health system, and societal perspectives. Methods. A prospective cohort study of newly referred people with PD to a specialist PD clinic in Melbourne, Australia. Participants completed baseline and monthly health resource use questionnaires and Medicare data were collected over 12 months. Results. 87 patients completed the 12-month follow-up assessments. The mean annual cost per person to the health care system was $32,556 AUD. The burden to society was an additional $45,000 per annum per person with PD. The largest component of health system costs were for hospitalisation (69% of total costs). The costs for people with moderate to severe disease were almost 4 times those with mild PD ($63,569 versus $17,537 p < 0.001). Conclusion. PD is associated with significant costs to individuals and to society. Costs escalated with disease severity suggesting that the burden to society is likely to grow with the increasing disease prevalence that is associated with population ageing.

Cancer-related fatigue: appraising evidence-based guidelines for screening, assessment and management.

PURPOSE: There is inconsistent management of cancer-related fatigue (CRF) by health professionals worldwide. This research aims to identify the most appropriate guidelines for the management of cancer-related fatigue. METHODS: A systematic search of international literature identified evidence-based clinical practice guidelines for CRF. Four reviewers independently appraised the highest quality guidelines using the AGREE-II instrument and National Heath and Medical Research Council (NHMRC) guideline standards. RESULTS: Five guidelines met the inclusion criteria. Of these, the 2015 Canadian Association of Psychosocial Oncology (CAPO) CRF guidelines and the 2014 American Society of Clinical Oncology (ASCO) fatigue guidelines for cancer survivors were selected for in-depth appraisal. The CAPO guideline scored higher than the ASCO for five domains of the AGREE-II. For one domain, the differences were statistically significant (p ≤ 0.05). The CAPO guideline met 37 of 47 NHMRC mandatory guideline standards and the ASCO guideline met 20. The difference in the proportion of standards met was statistically significant for one domain (p ≤ 0.05). Both guidelines had low scores for applicability and implementation. CONCLUSIONS: Currently, the CAPO guideline for cancer-related fatigue has the strongest evidence for use. To enhance implementation, further strategies for guideline dissemination and application are needed.

Evaluating the effects of increasing physical activity to optimize rehabilitation outcomes in hospitalized older adults (MOVE Trial): study protocol for a randomized controlled trial.

BACKGROUND: Older adults who have received inpatient rehabilitation often have significant mobility disability at discharge. Physical activity levels in rehabilitation are also low. It is hypothesized that providing increased physical activity to older people receiving hospital-based rehabilitation will lead to better mobility outcomes at discharge. METHODS/DESIGN: A single blind, parallel-group, multisite randomized controlled trial with blinded assessment of outcome and intention-to-treat analysis. The cost effectiveness of the intervention will also be examined. Older people (age >60 years) undergoing inpatient rehabilitation to improve mobility will be recruited from geriatric rehabilitation units at two Australian hospitals. A computer-generated blocked stratified randomization sequence will be used to assign 198 participants in a 1:1 ratio to either an 'enhanced physical activity' (intervention) group or a 'usual care plus' (control) group for the duration of their inpatient stay. Participants will receive usual care and either spend time each week performing additional physical activities such as standing or walking (intervention group) or performing an equal amount of social activities that have minimal impact on mobility such as card and board games (control group). Self-selected gait speed will be measured using a 6-meter walk test at discharge (primary outcome) and 6 months follow-up (secondary outcome). The study is powered to detect a 0.1 m/sec increase in self-selected gait speed in the intervention group at discharge. Additional measures of mobility (Timed Up and Go, De Morton Mobility Index), function (Functional Independence Measure) and quality of life will be obtained as secondary outcomes at discharge and tertiary outcomes at 6 months follow-up. The trial commenced recruitment on 28 January 2014. DISCUSSION: This study will evaluate the efficacy and cost effectiveness of increasing physical activity in older people during inpatient rehabilitation. These results will assist in the development of evidenced-based rehabilitation programs for this population.

Upper-limb assessment in people with Parkinson disease: is it a priority for therapists, and which assessment tools are used?

PURPOSE: To investigate the frequency of physiotherapy and occupational therapy assessment of the upper limb (UL) in people with Parkinson disease (PD) and to identify the impairments and activity limitations assessed and the methods used. METHOD: A custom-designed questionnaire was used to survey physiotherapists and occupational therapists with previous experience in managing people with PD, using targeted recruitment to invite physiotherapy conference attendees, clinicians employed in movement disorders programmes, and practitioners in neurology and gerontology to respond either on paper or online. RESULTS: Of the 190 respondents (122 physiotherapists, 68 occupational therapists), 54% reported consistently assessing the UL. A majority (>60%) assessed impairments specific to PD, but few quantified these using standardized measures. Activity limitations, largely relating to manual dexterity, were assessed using observational analysis (61%), non-standardized timed activities (46%), and standardized outcome measures (61%), most generic or developed for evaluating other neurological conditions. More than 10% of respondents could not identify an appropriate standardized measure. CONCLUSIONS: Slightly more than half of respondents regularly assessed the UL. Respondents reported widespread use of non-standardized methods to assess PD-specific impairments. Standardized measures were more frequently used to evaluate activity limitations, but despite the unique movement disorders associated with PD, the clinimetric properties of most of the tools identified have not been established in this population. Education and further clinimetric investigation of measures in use are needed to facilitate evidence-based practice in this area.

Objectif : Étudier la fréquence de l'évaluation des membres supérieurs en physiothérapie et en ergothérapie chez les personnes souffrant de la maladie de Parkinson (MP) et préciser les invalidités et les limitions d'activité qui font l'objet d'une évaluation ainsi que les méthodes utilisées. Méthodologie : Un questionnaire a été spécialement préparé à l'intention des physiothérapeutes et des ergothérapeutes qui avaient déjà de l'expérience dans la gestion de personnes souffrant de la MP. Un mode de recrutement ciblé a été utilisé pour inviter les participants à des conférences en physiothérapie, les cliniciens travaillant à des programmes de troubles du mouvement et les praticiens en neurologie et gérontologie à répondre au sondage. Le questionnaire pouvait être rempli en version papier ou par Internet. Résultats : Des 190 répondants (122 physiothérapeutes, 68 ergothérapeutes), 54 % ont dit procéder en continu à des évaluations des membres supérieurs. Une majorité (>60 %) a évalué les incapacités propres à la MP, mais peu d'entre eux ont quantifié les résultats à l'aide de mesures normalisées. Les limitations d'activité, liées en grande partie à des problèmes de dextérité manuelle, ont été évaluées à l'aide d'analyses par observation (61 %), d'activités minutées non normalisées (46 %) et de mesures de résultats normalisées (61 %), génériques ou créées pour l'évaluation d'autres troubles neurologiques. Plus de 10 % des répondants ne sont pas parvenus à identifier une mesure normalisée appropriée. Conclusions : Un peu plus de la moitié des répondants évaluaient régulièrement les membres supérieurs. Les répondants ont fait état d'une utilisation répandue de méthodes non normalisées pour l'évaluation d'incapacités propres à la MP. Des mesures normalisées étaient plus fréquemment utilisées pour évaluer les limitations d'activité, mais malgré les troubles du mouvement particuliers associés à la MP, les propriétés clinimétriques des instruments les plus couramment identifiés n'ont pas été établies dans ce groupe de patients. De l'éducation et des recherches clinimétriques supplémentaires sur ces mesures seront nécessaires pour favoriser une pratique fondée sur les faits probants dans ce domaine.

Protocol for a home-based integrated physical therapy program to reduce falls and improve mobility in people with Parkinson's disease.

BACKGROUND: The high incidence of falls associated with Parkinson's disease (PD) increases the risk of injuries and immobility and compromises quality of life. Although falls education and strengthening programs have shown some benefit in healthy older people, the ability of physical therapy interventions in home settings to reduce falls and improve mobility in people with Parkinson's has not been convincingly demonstrated. METHODS/DESIGN: 180 community living people with PD will be randomly allocated to receive either a home-based integrated rehabilitation program (progressive resistance strength training, movement strategy training and falls education) or a home-based life skills program (control intervention). Both programs comprise one hour of treatment and one hour of structured homework per week over six weeks of home therapy. Blinded assessments occurring before therapy commences, the week after completion of therapy and 12 months following intervention will establish both the immediate and long-term benefits of home-based rehabilitation. The number of falls, number of repeat falls, falls rate and time to first fall will be the primary measures used to quantify outcome. The economic costs associated with injurious falls, and the costs of running the integrated rehabilitation program from a health system perspective will be established. The effects of intervention on motor and global disability and on quality of life will also be examined. DISCUSSION: This study will provide new evidence on the outcomes and cost effectiveness of home-based movement rehabilitation programs for people living with PD. TRIAL REGISTRATION: The trial is registered on the Australian and New Zealand Clinical Trials Registry (ACTRN12608000390381).

Experiences of caregivers of people with Parkinson's disease in Singapore: a qualitative analysis.

AIMS AND OBJECTIVES: To conduct an in-depth qualitative examination of the experiences of Singaporean people caring for those with Parkinson's disease (PD). BACKGROUND: The need to provide care for people with PD will increase with the extended life expectancy of Singaporeans. Caring for people with PD in their own homes for as long as possible is argued to provide psychosocial benefits as well as benefiting the community by delayed institutionalisation and reduced healthcare costs. DESIGN: This study reports the qualitative exploratory component of a large mixed method sequential explanatory design. METHODS: Caregivers were selected through a purposive sampling technique and stratified based on the Hoehn and Yahr disease staging. Twenty-one semi-structured interviews were conducted in the home setting. Interviews were audio-taped and transcribed verbatim. The qualitative data were analysed using Ritchie and Spencer's framework method of qualitative analysis (1994, Analyzing Qualitative Data, Routledge, London). RESULTS: Seventeen (81%) caregivers were women, and their ages ranged from 31 years to more than 71 years. The length of the interview ranged from 42-106 minutes. The interview transcriptions produced 1731 free nodes, and after careful scrutiny for redundancy, 11 sub-themes were identified, which were organised into four key themes. These themes pertained to: (1) Coping and adaptation, (2) Challenges of caregiving, (3) Effects of caregiving on the caregivers and the (4) Need for better caregiver support. CONCLUSION: The results of this study have provided insights into the coping and well-being of caregivers of people with PD. The progressive nature of PD placed a significant burden on caregivers' emotional well-being. The findings of this study underscore the need for formal caregiver support and education to reduce strain in caregivers targeted at every stage of PD as there is no clear pattern of disease progression. RELEVANCE TO CLINICAL PRACTICE: This study has provided important findings that will inform the construction of interventional strategies to reduce caregiver burden and the provision of better support services for caregivers.

Quantifying the profile and progression of impairments, activity, participation, and quality of life in people with Parkinson disease: protocol for a prospective cohort study.

BACKGROUND: Despite the finding that Parkinson disease (PD) occurs in more than one in every 1000 people older than 60 years, there have been few attempts to quantify how deficits in impairments, activity, participation, and quality of life progress in this debilitating condition. It is unclear which tools are most appropriate for measuring change over time in PD. METHODS AND DESIGN: This protocol describes a prospective analysis of changes in impairments, activity, participation, and quality of life over a 12 month period together with an economic analysis of costs associated with PD. One-hundred participants will be included, provided they have idiopathic PD rated I-IV on the modified Hoehn & Yahr (1967) scale and fulfil the inclusion criteria. The study aims to determine which clinical and economic measures best quantify the natural history and progression of PD in a sample of people receiving services from the Victorian Comprehensive Parkinson's Program, Australia. When the data become available, the results will be expressed as baseline scores and changes over 3 months and 12 months for impairment, activity, participation, and quality of life together with a cost analysis. DISCUSSION: This study has the potential to identify baseline characteristics of PD for different Hoehn & Yahr stages, to determine the influence of disease duration on performance, and to calculate the costs associated with idiopathic PD. Valid clinical and economic measures for quantifying the natural history and progression of PD will also be identified. TRIAL REGISTRATION: ACTRN12609000008224.

Cost effectiveness of preventing falls and improving mobility in people with Parkinson disease: protocol for an economic evaluation alongside a clinical trial.

BACKGROUND: Cost of illness studies show that Parkinson disease (PD) is costly for individuals, the healthcare system and society. The costs of PD include both direct and indirect costs associated with falls and related injuries. METHODS: This protocol describes a prospective economic analysis conducted alongside a randomised controlled trial (RCT). It evaluates whether physical therapy is more cost effective than usual care from the perspective of the health care system. Cost effectiveness will be evaluated using a three-way comparison of the cost per fall averted and the cost per quality adjusted life year saved across two physical therapy interventions and a control group. CONCLUSION: This study has the potential to determine whether targetted physical therapy as an adjunct to standard care can be cost effective in reducing falls in people with PD. TRIAL REGISTRATION: No: ACTRN12606000344594.

High-Level Mobility Assessment Tool (HiMAT): interrater reliability, retest reliability, and internal consistency.

BACKGROUND AND PURPOSE: The High-Level Mobility Assessment Tool (HiMAT) assesses high-level mobility in people who have sustained a traumatic brain injury (TBI). The purpose of this study was to investigate the interrater reliability, retest reliability, and internal consistency of data obtained with the HiMAT. SUBJECTS: Three physical therapists and 103 people with TBI were recruited from a rehabilitation hospital. METHODS: Three physical therapists concurrently assessed a subset of 17 subjects with TBI to investigate interrater reliability. One physical therapist assessed a different subset of 20 subjects with TBI on 2 occasions, 2 days apart, to investigate retest reliability. Data from the entire sample of 103 subjects were used to investigate the internal consistency of this new scale. RESULTS: Both the interrater reliability (intraclass correlation coefficient [ICC]=.99) and the retest reliability (ICC=.99) of the HiMAT data were very high. For retest reliability, a small systematic change was detected (t=3.82, df=19), indicating a marginal improvement of 1 point at retest. Internal consistency also was very high (Cronbach alpha=.97). DISCUSSION AND CONCLUSION: The HiMAT is a new tool specifically designed to measure high-level mobility, which currently is not a component of existing scales used in TBI. This study demonstrated that the HiMAT is a reliable tool for measuring high-level mobility.

Evaluation of NHMRC funded research completed in 1992, 1997 and 2003: gains in knowledge, health and wealth.

OBJECTIVE: To report on strategies for, and outcomes of, evaluation of knowledge (publications), health and wealth (commercial) gains from medical research funded by the Australian Government through the National Health and Medical Research Council (NHMRC). DESIGN AND METHODS: End-of-grant reports submitted by researchers within 6 months of completion of NHMRC funded project grants which terminated in 2003 were used to capture self-reported publication number, health and wealth gains. Self-reported gains were also examined in retrospective surveys of grants completed in 1992 and 1997 and awards primarily supporting people ("people awards") held between 1992 and 2002. RESULTS: The response rate for the 1992 sample was too low for meaningful analysis. The mean number of publications per grant in the basic biomedical, clinical and health services research areas was very similar in 1997 and 2003. The publication output for population health was somewhat higher in the 2003 than in the 1997 analysis. For grants completed in 1997, 24% (31/131) affected clinical practice; 14% (18/131) public health practice; 9% (12/131) health policy; and 41% (54/131) had commercial potential with 20% (26/131) resulting in patents. Most respondents (89%) agreed that NHMRC people awards improved their career prospects. Interpretation is limited by the relatively low response rates (50% or less). CONCLUSIONS: A mechanism has been developed for ongoing assessment of NHMRC funded research. This process will improve accountability to the community and to government, and refine current funding mechanisms to most efficiently deliver health and economic returns for Australia.

The concurrent validity and responsiveness of the high-level mobility assessment tool for measuring the mobility limitations of people with traumatic brain injury.

OBJECTIVE: To investigate the concurrent validity and responsiveness of the High-Level Mobility Assessment Tool (HiMAT) in people after traumatic brain injury (TBI). DESIGN: This study compared the concurrent validity and responsiveness of the motor subsection of the FIM instrument and the gross function component of the Rivermead Motor Assessment (RMA) with the HiMAT, a new measure of high-level mobility developed for use in TBI. SETTING: A major rehabilitation hospital. PARTICIPANTS: A convenience sample of 103 participants with TBI were recruited from a major rehabilitation hospital. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: HiMAT, motor FIM, and the gross function RMA. RESULTS: The correlation between the HiMAT and motor FIM was moderate (r=.53, P<.001), largely because of a ceiling effect in the motor FIM. The correlation between the HiMAT and gross function RMA was strong (r=.87, P<.001), yet the gross function RMA was also susceptible to a ceiling effect, with 51.5% of subjects achieving the maximum score. The HiMAT was more responsive than the motor FIM and the gross function RMA on all indices. CONCLUSIONS: The HiMAT is a new unidimensional scale with moderate concurrent validity for measuring high-level mobility. The HiMAT is more responsive and has less of a ceiling effect than either the motor FIM or the gross function RMA.
