SummaryFalls in older people result in substantial health burden. Compelling evidence indicates that falls can be prevented. We developed comprehensive guidelines for economic evaluations of fall prevention interventions to facilitate publication of high-quality economic evaluations of the effective strategies and aid decision making.IntroductionThe importance of economics applied to falls and fall prevention in older people has largely been overlooked. The use of different methodologies to assess the costs and health benefits of the interventions and their comparators and the inconsistent reporting in the studies limits the usefulness of these economic evaluations for decision making. We developed guidelines to encourage and facilitate completion of high-quality economic evaluations of effective fall prevention strategies.MethodsWe used a generic checklist for economic evaluations as a platform to develop comprehensive guidelines for conducting and reporting economic evaluations of fall prevention strategies. We considered the many challenges involved, particularly in identifying, measuring, and valuing the relevant cost items.ResultsWe recommend researchers include cost outcomes and report incremental cost-effectiveness ratios in terms of falls prevented and quality adjusted life years in all clinical trials of fall prevention interventions. Studies should include the following cost categories: (1) implementing the intervention, (2) delivering the comparator group intervention, (3) total health care costs, (4) costs of fall-related health care resource use, and (5) personal and informal carer opportunity costs.ConclusionsThis paper provides a timely benchmark to promote comparability and consistency for conducting and reporting economic evaluations of fall prevention strategies.

Introduction Persons with cerebral palsy require a lifetime of costly and resource intensive interventions which are often limited by equity of access. With increasing burden being placed on health systems, new methods to deliver intensive rehabilitation therapies are needed. Move it to improve it (Mitii) is an internet-based multimodal programme comprising upper-limb and cognitive training with physical activity. It can be accessed in the clients home at their convenience. The proposed study aims to test the efficacy of Mitii in improving upper-limb function and motor planning. Additionally, this study hopes to further our understanding of the central neurovascular mechanisms underlying the proposed changes and determine the cost effectiveness of Mitii. Methods and analysis Children with congenital hemiplegia will be recruited to participate in this waitlist control, matched pairs, single-blind randomised trial. Children be matched at baseline and randomly allocated to receive 20 weeks of 30 min of daily Mitii training immediately, or waitlisted for 20 weeks before receiving the same Mitii training (potential total dose=70 h). Outcomes will be assessed at 20 weeks after the start of Mitii, and retention effects tested at 40 weeks. The primary outcomes will be the Assessment of Motor and Process Skills (AMPS), the Assisting Hand Assessment (AHA) and unimanual upper-limb capacity using the Jebsen-Taylor Test of Hand Function (JTTHF). Advanced brain imaging will assess use-dependant neuroplasticity. Measures of body structure and functions, activity, participation and quality of life will be used to assess Mitii efficacy across all domains of the International Classification of Functioning, Disability and Health framework. Ethics and dissemination This project has received Ethics Approval from the Medical Ethics Committee of The University of Queensland (2011000608) and the Royal Childrens Hospital Brisbane (HREC/11/QRCH/35). Findings will be disseminated widely through conference presentations, seminars and peer-reviewed scientific journals. Trial registration ACTRN12611001174976

Taxation has been suggested as a possible preventive strategy to address the serious public health concern of childhood obesity. Understanding the public’s viewpoint on the potential role of taxation is vital to inform policy decisions if they are to be acceptable to the wider community. A Citizens’ Jury is a deliberative method for engaging the public in decision making and can assist in setting policy agendas. A Citizens’ Jury was conducted in Brisbane, Australia in May 2013 to answer the question: Is taxation on food and drinks an acceptable strategy to the public in order to reduce rates of childhood obesity? Citizens were randomly selected from the electoral roll and invited to participate. Thirteen members were purposively sampled from those expressing interest to broadly reflect the diversity of the Australian public. Over two days, participants were presented with evidence on the topic by experts, were able to question witnesses and deliberate on the evidence. The jurors unanimously supported taxation on sugar-sweetened drinks but generally did not support taxation on processed meats, snack foods and foods eaten/ purchased outside the home. They also supported taxation on snack foods on the condition that traffic light labelling was also introduced. Though they were not specifically asked to deliberate strategies outside of taxation, the jurors strongly recommended more nutritional information on all food packaging using the traffic light and teaspoon labelling systems for sugar, salt and fat content. The Citizens’ Jury suggests that the general public may support taxation on sugar-sweetened drinks to reduce rates of obesity in children. Regulatory reforms of taxation on sugar-sweetened drinks and improved labelling of nutritional information on product packaging were strongly supported by all members of the jury. These reforms should be considered by governments to prevent childhood obesity and the future burden on society from the consequences of obesity.

BackgroundA key goal for services treating older persons is improving Quality of Life (QoL). This study aimed to 1) determine the QoL and utility (i.e. satisfaction with own quality of life) for participants of a discharge program for older people following an extended hospital episode of care and 2) examine the impact of the intensity of this program on utility gains over time.MethodsA prospective observational cohort study with baseline and repeated measures follow up of 351 participants of the transition care program in six community sites in two states of Australia was conducted. All participants who gave consent to participate were eligible for the study. QoL and utility of the participants were measured at baseline, end of program, three and six months post baseline using the EQ-5D and ICECAP-O. Association between the intensity of the program, measured in hours of care given, and improvement in utility were tested using linear regression.ResultsThe ICECAP-O yielded consistently higher utility values than the EQ-5D at all time points. Baseline mean (sd) utility scores were 0.55 (0.20) and 0.75(0.16) and at six months were 0.60 (0.28) and 0.84 (0.25) for the EQ-5D and ICECAP-O respectively. The ICECAP-O showed a significant improvement over time. The intensity of the post-acute program measured by hours delivered was positively associated with utility gains in this cohort.ConclusionsA discharge program for older frail people following an extended hospital episode of care appears to maintain and generate improvements in QoL. The amount of gain was positively influenced by the intensity of the program.

The aim of this study is to investigate the effects of onsite workplace health-enhancing physical activity (HEPA) programmes on worker productivity. The PROSPERO registration number is CRD42014008750. A search for controlled trials or randomised controlled trials (RCTs) that investigated the effects of onsite workplace HEPA programmes on productivity levels of working adults was performed. Risk of bias of included studies was assessed, and the inter-rater reliability of the quality assessment was analysed. Qualitative synthesis of available evidence is presented. Eight studies were included in the review. There is consistent evidence that onsite workplace HEPA programmes do not reduce levels of sick leave. There appears to be inconsistent evidence of the impact of onsite workplace HEPA programmes on worker productivity. A high-quality study of an onsite combination (aerobic, strengthening and flexibility) HEPA regime and a moderate-quality study of a Tai Chi programme improved worker productivity measured with questionnaires in female laundry workers and older female nurses, respectively. Two high-quality studies and four moderate-quality studies did not show benefit. Studies that showed benefit were mainly those designed with productivity measures as primary outcomes, delivered to occupations involved with higher physical loads, and had higher compliance and programme intensity. The small number of studies and the lack of consistency among studies limited further analyses. There is inconsistent evidence that onsite workplace HEPA programmes improve self-reported worker productivity. Future high-quality RCTs of onsite workplace HEPA programmes should be designed around productivity outcomes, target at-risk groups and investigate interventions of sufficient intensity. High attendance with improved recording is needed to achieve significant results in augmenting worker productivity.

There is an increasing demand for acute care services due in part to rising proportions of older people and increasing rates of chronic diseases. To reduce pressure and costs in the hospital system, community-based post-acute care discharge services for older people have evolved as one method of reducing length of stay in hospital and preventing readmissions. However, it is unclear whether they reduce overall episode cost or expenditure in the health system at a more general level. In this paper, we review the current evidence on the likely costs and benefits of these services and consider whether they are potentially cost-effective from a health services perspective, using the Australian Transition Care Programme as a case study. Evaluations of community-based post-acute services have demonstrated that they reduce length of stay, prevent some re-hospitalisations and defer nursing home placement. There is also evidence that they convey some additional health benefits to older people. An economic model was developed to identify the maximum potential benefits and the likely cost savings from reduced use of health services from earlier discharge from hospital, accelerated recovery, reduced likelihood of readmission to hospital and delayed entry into permanent institutional care for participants of the Transition Care Programme. Assuming the best case scenario, the Transition Care Programme is still unlikely to be cost saving to a healthcare system. Hence for this service to be justified, additional health benefits such as quality of life improvements need to be taken into account. If it can be demonstrated that this service also conveys additional quality of life improvements, community-based programmes such as Transition Care could be considered to be cost-effective when compared with other healthcare programmes.

BACKGROUND older people are high users of healthcare resources. The frailty index can predict negative health outcomes; however, the amount of extra resources required has not been quantified. OBJECTIVE to quantify the impact of frailty on healthcare expenditure and resource utilisation in a patient cohort who entered a community-based post-acute program and compare this to a cohort entering residential care. METHODS the interRAI home care assessment was used to construct a frailty index in three frailty levels. Costs and resource use were collected alongside a prospective observational cohort study of patients. A generalized linear model was constructed to estimate the additional cost of frailty and the cost of alternative residential care for those with high frailty. RESULTS participants (n = 272) had an average age of 79, frailty levels were low in 20%, intermediate in 50% and high in 30% of the cohort. Having an intermediate or high level of frailty increased the likelihood of re-hospitalisation and was associated with 22 and 43% higher healthcare costs over 6 months compared with low frailty. It was less costly to remain living at home than enter residential care unless >62% of subsequent hospitalisations in 6 months could be prevented. CONCLUSIONS the frailty index can potentially be used as a tool to estimate the increase in healthcare resources required for different levels of frailty. This information may be useful for quantifying the amount to invest in programs to reduce frailty in the community.

BACKGROUND To compare the effect of two modes of delivering a falls prevention service in reducing the rate of falls and improving quality of life, activity levels, and physical status among older adults with a history of recent falls. METHODS A randomized controlled trial was conducted with a total of 107 participants with blinded baseline and follow-up assessments. The participants were older community-dwelling adults referred for a falls prevention service located in Brisbane, Australia. The intervention was a multiple component falls prevention service delivered in either in a domiciliary or center-based mode of delivery. Both programs were similar apart from setting and consisted of three components, a balance and strength component, falls prevention education, and functional tasks. Physical and psychosocial assessments were administered at baseline, 8-week follow-up and 6-month follow-up. Falls data were collected by monthly telephone contact and by interview at 8 weeks and 6 months. RESULTS The center-based service demonstrated significantly better results in preventing falls over the home-based service. Clients in the center-based arm of the trial experienced fewer total falls and this group also had a greater reduction in the total number of fallers after the intervention. CONCLUSION This research demonstrates that delivering a similar service in different settings-home based or center based-impacts upon the effectiveness of the service. Community-dwelling older adults with a history of falls should be provided with center-based programs in preference to home-based programs where they are available.

BackgroundModern healthcare managers are faced with pressure to deliver effective, efficient services within the context of fixed budget constraints. Managers are required to make decisions regarding the skill mix of the workforce particularly when staffing new services. One measure used to identify numbers and mix of staff in healthcare settings is workforce ratio. The aim of this study was to identify workforce ratios in nine allied health professions and to identify whether these measures are useful for planning allied health workforce requirements.MethodsA systematic literature search using relevant MeSH headings of business, medical and allied health databases and relevant grey literature for the period 2000-2008 was undertaken.ResultsTwelve articles were identified which described the use of workforce ratios in allied health services. Only one of these was a staffing ratio linked to clinical outcomes. The most comprehensive measures were identified in rehabilitation medicine.ConclusionThe evidence for use of staffing ratios for allied health practitioners is scarce and lags behind the fields of nursing and medicine.

Objective Non-surgical treatment can be effective for many musculoskeletal conditions. Improving access to these options may improve the efficiency of hospitals. The Orthopaedic Physiotherapy Screening Clinic and Multidisciplinary Service offers early comprehensive assessment and coordinated, patient-centred care within a multidisciplinary framework. Our aim was to assess its cost-effectiveness compared with usual orthopaedic care. Methods A Markov model was constructed to estimate the quality-adjusted life years and health care costs from the perspective of health care payers for outpatients with low back, knee or shoulder conditions compared to usual orthopaedic care. Data were obtained from a retrospective chart review, administrative sources, literature and expert opinion. The time frame was five years and all costs were reported in 2011
