Study protocol for The GOAL Trial: comprehensive geriatric assessment for frail older people with chronic kidney disease to increase attainment of patient-identified goals-a cluster randomised controlled trial

BACKGROUND

An increasing number of older people are living with chronic kidney disease (CKD). Many have complex healthcare needs and are at risk of deteriorating health and functional status, which can adversely affect their quality of life. Comprehensive geriatric assessment (CGA) is an effective intervention to improve survival and independence of older people, but its clinical utility and cost-effectiveness in frail older people living with CKD is unknown.

METHODS

The GOAL Trial is a pragmatic, multi-centre, open-label, superiority, cluster randomised controlled trial developed by consumers, clinicians, and researchers. It has a two-arm design, CGA compared with standard care, with 1:1 allocation of a total of 16 clusters. Within each cluster, study participants ≥ 65 years of age (or ≥ 55 years if Aboriginal or Torres Strait Islander (First Nations Australians)) with CKD stage 3-5/5D who are frail, measured by a Frailty Index (FI) of > 0.25, are recruited. Participants in intervention clusters receive a CGA by a geriatrician to identify medical, social, and functional needs, optimise medication prescribing, and arrange multidisciplinary referral if required. Those in standard care clusters receive usual care. The primary outcome is attainment of self-identified goals assessed by standardised Goal Attainment Scaling (GAS) at 3 months. Secondary outcomes include GAS at 6 and 12 months, quality of life (EQ-5D-5L), frailty (Frailty Index - Short Form), transfer to residential aged care facilities, cost-effectiveness, and safety (cause-specific hospitalisations, mortality). A process evaluation will be conducted in parallel with the trial including whether the intervention was delivered as intended, any issue or local barriers to intervention delivery, and perceptions of the intervention by participants. The trial has 90% power to detect a clinically meaningful mean difference in GAS of 10 units.

DISCUSSION

This trial addresses patient-prioritised outcomes. It will be conducted, disseminated and implemented by clinicians and researchers in partnership with consumers. If CGA is found to have clinical and cost-effectiveness for frail older people with CKD, the intervention framework could be embedded into routine clinical practice. The implementation of the trial's findings will be supported by presentations at conferences and forums with clinicians and consumers at specifically convened workshops, to enable rapid adoption into practice and policy for both nephrology and geriatric disciplines. It has potential to materially advance patient-centred care and improve clinical and patient-reported outcomes (including quality of life) for frail older people living with CKD.

The Effect of Price Changes and Teaspoon Labelling on Intention to Purchase Sugar-Sweetened Beverages: A Discrete Choice Experiment

INTRODUCTION

Childhood obesity is a major public health concern and sugar-sweetened beverages (SSBs) are a known contributor. SSB taxation and food labelling have been proposed as policies to reduce consumption by changing purchasing behaviours. The study aimed to analyse caregivers' preferences on commonly purchased SSBs in Australia and to determine the effect of price increases and teaspoon labelling on their purchasing intentions.

METHODS

We used a discrete choice experiment (DCE) to obtain data about choices between SSB and non-SSB alternatives. 563 caregivers, who had young children aged 3-7 years, completed the experiment online. 286 were randomly allocated to receive choice sets with plain labelling while 277 were assigned to teaspoon labelling. Each participant completed nine choice scenarios where they chose between six SSB and non-SSB beverage options or a no-beverage option, with beverage prices varying between scenarios. While hypothetical, price and teaspoon labelling for sugar content for each beverage was obtained from an informal market survey. Responses from the DCE were modelled using random parameters logit within a random utility theory framework. Household income and children's consumption volumes of soft drink were used to explore preference heterogeneity.

RESULTS

Using mixed logit as the final model, we found that higher reduction in intended purchases was observed for soft drink and fruit drink in teaspoon labelling than it was in plain labelling. Participants exposed to teaspoon labelling intended to purchase less of flavoured milk and fruit juice compared to those exposed to plain labelling. Compared to baseline prices, a hypothetical 20% increase in SSB prices and the presentation of 'teaspoons of sugar' labelling were predicted to reduce intentional SSB purchases and increase intentional non-SSB purchases. Within each labelling group, there were no significant differences of intentional purchases between the highest and the lowest income quintile, high and low consumers of soft drinks. However, compared to plain labelling, teaspoon labelling was predicted to strongly influence intentional purchases of SSBs and non-SSBs.

CONCLUSION

This study suggests that a policy to increase SSB price and include teaspoon labelling would lead to a reduced consumption of SSBs and increased consumption of non-SSBs.

Public hesitancy to COVID‐19 vaccine and the role of pharmacists in addressing the problem and improving uptake

COVID‐19 is one of the worst pandemics in recent human history, causing huge health, economic, and psychosocial damage. Since the pandemic hit, several unsubstantiated claims regarding exposure, transmission and management have been disseminated. Misinformation and associated public confusion now extend to the COVID‐19 vaccines, spanning from claims based on possible links between some vaccine types and rare blood clots, to baseless claims. As a result, the public’s trust in COVID‐19 vaccines has been eroded, fuelling an already troubling trend of vaccine hesitancy. As medication experts and the most accessible healthcare providers, pharmacists are well equipped with the required skills and knowledge to improve COVID‐19 vaccine uptake by taking roles that range from dispelling myths, to providing reliable evidence‐based information, through to vaccine administration. This paper discusses public hesitancy to COVID‐19 vaccines, major contributing factors, and the role pharmacists can play in reducing hesitancy and increasing vaccine uptake.

Systematised, Interdisciplinary Malnutrition Program for impLementation and Evaluation delivers improved hospital nutrition care processes and patient reported experiences - An implementation study

AIM

Models of hospital malnutrition care reliant on dietitians can be inefficient and of limited effectiveness. This study evaluated whether implementing the Systematised, Interdisciplinary Malnutrition Program for impLementation and Evaluation (SIMPLE) improved hospital nutrition care processes and patientreported experiences compared with traditional practice.

METHODS

A multi-site (five hospitals) prospective, pre-post study evaluated the facilitated implementation of SIMPLE, a malnutrition care pathway promoting proactive nutrition support delivered from time of malnutrition screening by the interdisciplinary team, without need for prior dietetic assessment. Implementation was tailored to local site needs and resources. Nutrition care processes delivered to inpatients who were malnourished or at-risk of malnutrition were identified across diagnosis, intervention, and monitoring domains using standardised audits from medical records, foodservice systems and patient-reported nutrition experience measures.

RESULTS

Pre-implementation (n = 365) and post-implementation (n = 397) cohorts were similar for age (74 vs 73 years), gender (47.1% vs 48.6% female), and nutrition risk status (46.6% vs 45.3% at-risk). Post-implementation, at-risk participants were more likely to receive enhanced food and fluids (68.5% vs 83.9%; P < .01), nutrition information (30.9% vs 47.2%; P < .01), mealtime assistance where required (61.4% vs 77.9% P = .04), nutrition monitoring (25.2% vs 46.3%; P < .01) and care planning (17.8% vs 27.7%; P = .01). Patient-reported nutrition experience measures confirmed improved nutrition care. There was no difference in dietetic occasions of service per patient (1.51 vs 1.25; P = .83).

CONCLUSIONS

Tailored SIMPLE implementation improves nutrition care processes and patient reported nutrition experience measures for at-risk inpatients within existing dietetic resources.

A cluster-randomized trial of workplace ergonomics and neck-specific exercise versus ergonomics and health promotion for office workers to manage neck pain - a secondary outcome analysis

Background

Neck pain is prevalent among office workers. This study evaluated the impact of an ergonomic and exercise training (EET) intervention and an ergonomic and health promotion (EHP) intervention on neck pain intensity among the All Workers and a subgroup of Neck Pain cases at baseline.

Methods

A 12-month cluster-randomized trial was conducted in 14 public and private organisations. Office workers aged ≥18 years working ≥30 h per week (n = 740) received an individualised workstation ergonomic intervention, followed by 1:1 allocation to the EET group (neck-specific exercise training), or the EHP group (health promotion) for 12 weeks. Neck pain intensity (scale: 0–9) was recorded at baseline, 12 weeks, and 12 months. Participants with data at these three time points were included for analysis (n = 367). Intervention group differences were analysed using generalized estimating equation models on an intention-to-treat basis and adjusted for potential confounders. Subgroup analysis was performed on neck cases reporting pain ≥3 at baseline (n = 96).

Results

The EET group demonstrated significantly greater reductions in neck pain intensity at 12 weeks compared to the EHP group for All Workers (EET: β = − 0.53 points 95% CI: − 0.84– − 0.22 [36%] and EHP: β = − 0.17 points 95% CI: − 0.47–0.13 [10.5%], p-value = 0.02) and the Neck Cases (EET: β = − 2.32 points 95% CI: − 3.09– − 1.56 [53%] and EHP: β = − 1.75 points 95% CI: − 2.35– − 1.16 [36%], p = 0.04). Reductions in pain intensity were not maintained at 12 months with no between-group differences observed in All Workers (EET: β = − 0.18, 95% CI: − 0.53–0.16 and EHP: β = − 0.14 points 95% CI: − 0.49–0.21, p = 0.53) or Neck Cases, although in both groups an overall reduction was found (EET: β = − 1.61 points 95% CI: − 2.36– − 0.89 and EHP: β = − 1.9 points 95% CI: − 2.59– − 1.20, p = 0.26).

Conclusion

EET was more effective than EHP in reducing neck pain intensity in All Workers and Neck Cases immediately following the intervention period (12 weeks) but not at 12 months, with changes at 12 weeks reaching clinically meaningful thresholds for the Neck Cases. Findings suggest the need for continuation of exercise to maintain benefits in the longer term.

Determining if Telehealth Can Reduce Health System Costs: Scoping Review

Background

Telehealth represents an opportunity for Australia to harness the power of technology to redesign the way health care is delivered. The potential benefits of telehealth include increased accessibility to care, productivity gains for health providers and patients through reduced travel, potential for cost savings, and an opportunity to develop culturally appropriate services that are more sensitive to the needs of special populations. The uptake of telehealth has been hindered at times by clinician reluctance and policies that preclude metropolitan populations from accessing telehealth services.

Objective

This study aims to investigate if telehealth reduces health system costs compared with traditional service models and to identify the scenarios in which cost savings can be realized.

Methods

A scoping review was undertaken to meet the study aims. Initially, literature searches were conducted using broad terms for telehealth and economics to identify economic evaluation literature in telehealth. The investigators then conducted an expert focus group to identify domains where telehealth could reduce health system costs, followed by targeted literature searches for corresponding evidence.

Results

The cost analyses reviewed provided evidence that telehealth reduced costs when health system–funded travel was prevented and when telehealth mitigated the need for expensive procedural or specialist follow-up by providing competent care in a more efficient way. The expert focus group identified 4 areas of potential savings from telehealth: productivity gains, reductions in secondary care, alternate funding models, and telementoring. Telehealth demonstrated great potential for productivity gains arising from health system redesign; however, under the Australian activity-based funding, it is unlikely that these gains will result in cost savings. Secondary care use mitigation is an area of promise for telehealth; however, many studies have not demonstrated overall cost savings due to the cost of administering and monitoring telehealth systems. Alternate funding models from telehealth systems have the potential to save the health system money in situations where the consumers pay out of pocket to receive services. Telementoring has had minimal economic evaluation; however, in the long term it is likely to result in inadvertent cost savings through the upskilling of generalist and allied health clinicians.

Conclusions

Health services considering implementing telehealth should be motivated by benefits other than cost reduction. The available evidence has indicated that although telehealth provides overwhelmingly positive patient benefits and increases productivity for many services, current evidence suggests that it does not routinely reduce the cost of care delivery for the health system.

Valuing the AD-5D Dementia Utility Instrument: An Estimation of a General Population Tariff

OBJECTIVE

This paper reports on the valuation of quality-of-life states in the Alzheimer's Disease Five Dimensions (AD-5D) instrument in a representative sample of the general population in Australia using the discrete-choice experiment with duration (DCE_TTO) elicitation technique.

METHOD

A DCE with 200 choice sets of two quality-of-life (QoL) state-duration combinations blocked into 20 survey versions, with ten choice sets in each version, was designed and administered online to a sample representative of the Australian population. Two additional choice sets comprising internal consistency and dominance checks were included in each survey version. A range of model specifications investigating preferences with respect to duration and interactions between AD-5D dimension levels were estimated. Utility weights were developed, with estimated coefficients transformed to the 0 (being dead) to 1 (full health) scale, suitable for the calculation of quality-adjusted life-year (QALY) weights for use in economic evaluation.

RESULTS

In total, 1999 respondents completed the choice experiment. Overall, respondents were slightly better educated and had higher annual incomes than the Australian general population. The estimation results from different specifications and models were broadly consistent with the monotonic nature of the AD-5D: utility increased with increased life expectancy and decreased as the severity level for each dimension worsened. A utility value set was generated for the calculation of utilities for all QoL states defined by the AD-5D descriptive system.

CONCLUSION

The DCE-based utility value set is now available to use to generate QALYs for the economic evaluation of treatments and interventions targeting people with dementia and/or their family caregivers.

A uniform data set for determining outcomes in allied health primary contact services in Australia

The project aim was to develop and implement a set of metrics to capture and demonstrate the performance of newly established allied health primary contact services. Selection of the metrics and performance indicators was guided by an existing state-wide data collection system and from a review of the published literature. The metrics were refined after consultation with a working group of health service managers and clinicians. The data collection and reporting framework were developed for use in allied health primary contact services and implemented at public health facilities in Queensland, Australia. The set of metrics consists of 18 process and outcome measures. Patient-reported metrics include the global rating of change scale and patient satisfaction. Service metrics include wait times; referral source; triage category; diagnosis; occasions of service; referrals and investigations initiated; effects; care duration; discharge status; waitlist reinstatement reasons; treatment non-completion reasons; and expedited care. Safety, patient demographics and service improvement metrics were included. The metrics will enable analysis of the effectiveness of allied health primary contact services and will facilitate reporting, advocacy, service improvement, service continuity and research. The metrics are suitable for use by all providers of allied health primary contact services in hospital and primary care settings.

Implementation of simulation modelling to improve service planning in specialist orthopaedic and neurosurgical outpatient services

BACKGROUND

Advanced physiotherapist-led services have been embedded in specialist orthopaedic and neurosurgical outpatient departments across Queensland, Australia, to ameliorate capacity constraints. Simulation modelling has been used to inform the optimal scale and professional mix of services required to match patient demand. The context and the value of simulation modelling in service planning remain unclear. We aimed to examine the adoption, context and costs of using simulation modelling recommendations to inform service planning.

METHODS

Using an implementation science approach, we undertook a prospective, qualitative evaluation to assess the use of discrete event simulation modelling recommendations for service re-design and to explore stakeholder perspectives about the role of simulation modelling in service planning. Five orthopaedic and neurosurgical services in Queensland, Australia, were selected to maximise variation in implementation effectiveness. We used the consolidated framework for implementation research (CFIR) to guide the facilitation and analysis of the stakeholder focus group discussions. We conducted a prospective costing analysis in each service to estimate the costs associated with using simulation modelling to inform service planning.

RESULTS

Four of the five services demonstrated adoption by inclusion of modelling recommendations into proposals for service re-design. Four CFIR constructs distinguished and two CFIR constructs did not distinguish between high versus mixed implementation effectiveness. We identified additional constructs that did not map onto CFIR. The mean cost of implementation was AU$34,553 per site (standard deviation = AU$737).

CONCLUSIONS

To our knowledge, this is the first time the context of implementing simulation modelling recommendations in a health care setting, using a validated framework, has been examined. Our findings may provide valuable insights to increase the uptake of healthcare modelling recommendations in service planning.

Milk Other Than Breast Milk and the Development of Asthma in Children 3 Years of Age. A Birth Cohort Study (2006⁻2011)

Prevalence of asthma in Australian children is amongst the highest in the world. Although breastfeeding positively influences infant immunity, early introduction of Milk Other than Breast Milk (MOTBM) may also play an important role in the development of Asthma. The aim of this study was to investigate the association between the introduction of MOTBM in the first six months after birth and the development of reported persistent asthma in 3-year olds. A sample of 1121 children was extracted from the Environments for Healthy Living longitudinal birth cohort study. Introduction of MOTBM during the first six months after birth increased almost two-fold the risk of development of persistent asthma after adjusting for other covariates (Adjusted Relative Risk (ARR): 1.71, 95% CI: 1.03⁻2.83, p = 0.038). This study indicates that the introduction of MOTBM in the first six months of life is a risk factor for asthma incidence among 3-year old children. This result is important in explaining the benefits of breastfeeding as part of public health interventions to encourage mothers to increase breastfeeding initiation and duration, and avoid the introduction of MOTBM in the first six months after childbirth.

Implementation of an evidence-based intervention to improve the wellbeing of people with dementia and their carers: study protocol for 'Care of People with dementia in their Environments (COPE)' in the Australian context

BACKGROUND

There are effective non-pharmacological treatment programs that reduce functional disability and changed behaviours in people with dementia. However, these programs (such as the Care of People with dementia in their Environments (COPE) program) are not widely available. The primary aim of this study is to determine the strategies and processes that enable the COPE program to be implemented into existing dementia care services in Australia.

METHODS

This study uses a mixed methods approach to test an implementation strategy. The COPE intervention (up to ten consultations with an occupational therapist and up to two consultations with a nurse) will be implemented using a number of strategies including planning (such as developing and building relationships with dementia care community service providers), educating (training nurses and occupational therapists in how to apply the intervention), restructuring (organisations establishing referral systems; therapist commitment to provide COPE to five clients following training) and quality management (coaching, support, reminders and fidelity checks). Qualitative and quantitative data will contribute to understanding how COPE is adopted and implemented. Feasibility, fidelity, acceptability, uptake and service delivery contexts will be explored and a cost/benefit evaluation conducted. Client outcomes of activity engagement and caregiver wellbeing will be assessed in a pragmatic pre-post evaluation.

DISCUSSION

While interventions that promote independence and wellbeing are effective and highly valued by people with dementia and their carers, access to such programs is limited. Barriers to translation that have been previously identified are addressed in this study, including limited training opportunities and a lack of confidence in clinicians working with complex symptoms of dementia. A strength of the study is that it involves implementation within different types of existing services, such as government and private providers, so the study will provide useful guidance for further future rollout.

Developing a dementia-specific preference--based quality of life measure (AD-5D) in Australia: a valuation study protocol

INTRODUCTION

Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia. The Quality of Life in Alzheimer's Disease (QOL-AD) is a widely used and well-validated condition-specific instrument for assessing health-related quality of life for people living with dementia, but it does not enable the calculation of quality-adjusted life years, the basis of cost utility analysis. This study will generate a preference-based scoring algorithm for a health state classification system -the Alzheimer's Disease Five Dimensions (AD-5D) derived from the QOL-AD.

METHODS AND ANALYSIS

Discrete choice experiments with duration (DCE_TTO) and best-worst scaling health state valuation tasks will be administered to a representative sample of 2000 members of the Australian general population via an online survey and to 250 dementia dyads (250 people with dementia and their carers) via face-to-face interview. A multinomial (conditional) logistic framework will be used to analyse responses and produce the utility algorithm for the AD-5D.

ETHICS AND DISSEMINATION

The algorithms developed will enable prospective and retrospective economic evaluation of any treatment or intervention targeting people with dementia where the QOL-AD has been administered and will be available online. Results will be disseminated through journals that publish health economics articles and through professional conferences. This study has ethical approval.

An empirical comparison of Markov cohort modeling and discrete event simulation in a capacity-constrained health care setting

OBJECTIVES

To empirically compare Markov cohort modeling (MM) and discrete event simulation (DES) with and without dynamic queuing (DQ) for cost-effectiveness (CE) analysis of a novel method of health services delivery where capacity constraints predominate.

METHODS

A common data-set comparing usual orthopedic care (UC) to an orthopedic physiotherapy screening clinic and multidisciplinary treatment service (OPSC) was used to develop a MM and a DES without (DES-no-DQ) and with DQ (DES-DQ). Model results were then compared in detail.

RESULTS

The MM predicted an incremental CE ratio (ICER) of $495 per additional quality-adjusted life-year (QALY) for OPSC over UC. The DES-no-DQ showed OPSC dominating UC; the DES-DQ generated an ICER of $2342 per QALY.

CONCLUSIONS

The MM and DES-no-DQ ICER estimates differed due to the MM having implicit delays built into its structure as a result of having fixed cycle lengths, which are not a feature of DES. The non-DQ models assume that queues are at a steady state. Conversely, queues in the DES-DQ develop flexibly with supply and demand for resources, in this case, leading to different estimates of resource use and CE. The choice of MM or DES (with or without DQ) would not alter the reimbursement of OPSC as it was highly cost-effective compared to UC in all analyses. However, the modeling method may influence decisions where ICERs are closer to the CE acceptability threshold, or where capacity constraints and DQ are important features of the system. In these cases, DES-DQ would be the preferred modeling technique to avoid incorrect resource allocation decisions.

Comparison of four alternative national universal anterior cruciate ligament injury prevention programme implementation strategies to reduce secondary future medical costs

BACKGROUND/AIM

Anterior cruciate ligament (ACL) injury is a common and devastating sporting injury. With or without ACL reconstruction, the risk of knee osteoarthritis (OA) and permanent disability later in life is markedly increased. While neuromuscular training programmes can prevent 50-80% of ACL injuries, no national implementation strategies exist in Australia. The aim of this study was to compare the ability of four alternative national universal ACL injury prevention programme implementation strategies to reduce future medical costs secondary to ACL injury.

METHODS

A Markov economic decision model was constructed to estimate the value in lifetime future medical costs prevented by implementing a national ACL prevention programme among four hypothetical cohorts: high-risk sport participants (HR) aged 12-25 years; HR 18-25 years; HR 12-17 years; all youths (ALL) 12-17 years.

RESULTS

Of the four programmes examined, the HR 12-25 programme provided the greatest value, averting US$693 of direct healthcare costs per person per lifetime or US$221 870 880 in total. Without training, 9.4% of this cohort will rupture their ACL and 16.8% will develop knee OA. Training prevents 3764 lifetime ACL ruptures per 100 000 individuals, a 40% reduction in ACL injuries. 842 lifetime cases of OA per 100 000 individuals and 584 TKRs per 100 000 are subsequently averted. Numbers needed to treat ranged from 27 for the HR 12-25 to 190 for the ALL 12-17.

CONCLUSIONS

The HR 12-25 programme was the most effective implementation strategy. Estimation of the break-even cost of health expenditure savings will enable optimal future programme design, implementation and expenditure.

Exploration of the economic and quality of life impact on carers of individuals undergoing community rehabilitation

Background/Aims:

For people with neurological conditions, informal carers form an important part of the rehabilitation journey. The aim of the current study was to assess the economic and quality of life outcomes for someone caring for a person undertaking a community rehabilitation programme.

Methods:

A prospective study was conducted of a community rehabilitation service with baseline and 3-month follow-up data. Participants in this study were carers of people undergoing rehabilitation. Data was collected on time spent caring and on employment status using a questionnaire. Quality of life was measured using the carer experience scale.

Results:

Carers spend an average of 28 hours per week in caring activities and this was similar after rehabilitation was complete. Replacement by a paid worker would cost over A$650 a week. Quality of life of the carer did not significantly change after rehabilitation was completed. Thirty-seven percent of carers have ceased work because of their caring duties.

Conclusions:

Three months may be too short to measure the impact of rehabilitation on carers. Carers represent a substantial economic resource and carers are at increased risk of poverty because of their caring duties. Integrating carers into the rehabilitation process may help improve outcomes for carers as well as for clients of community rehabilitation services.

Healthcare resource use in patients of the Australian Transition Care Program

OBJECTIVE

The aim of the present study was to describe, from the perspective of the healthcare funder, the cost components of the Australian Transition Care Program (TCP) and the healthcare resource use and costs for a group of transition care clients over a 6-month period following admission to the program.

METHODS

A prospective cohort observational study of 351 consenting patients entering community-based transition care at six sites in two states in Australia from November 2009 to September 2010 was performed. Patients were followed up 6 months after admission to the TCP to ascertain current living status and hospital re-admissions over the follow-up period. Cost data were collected by transition care teams and from administrative data (hospital and Medicare records).

RESULTS

The TCP provides a range of services with most costs attributed to provision of personal care support, case management, physiotherapy and occupational therapy. Most healthcare costs up to 6 months after transition care admission were incurred from the hospital admission leading to transition care and from re-admissions. Orthopaedic conditions incurred the highest costs, with many of these for elective procedures and others resulting from falls. Hospital re-admission rates in the present study were 10% lower than in a previous evaluation ofthe TCP. Over 6 months, approximately 40% of patients in the study were re-admitted to hospital at an average cost of A$7038.

CONCLUSIONS

Although the cost of the TCP is relatively high, it may have some impact on reducing hospital re-admissions and preventing or delaying residential care admissions.

The increase in healthcare costs associated with frailty in older people discharged to a post-acute transition care program

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.

Mitii™ ABI: study protocol of a randomised controlled trial of a web-based multi-modal training program for children and adolescents with an Acquired Brain Injury (ABI)

BACKGROUND

Acquired brain injury (ABI) refers to multiple disabilities arising from damage to the brain acquired after birth. Children with an ABI may experience physical, cognitive, social and emotional-behavioural impairments which can impact their ability to participate in activities of daily living (ADL). Recent developments in technology have led to the emergence of internet-delivered therapy programs. "Move it to improve it" (Mitii™) is a web-based multi-modal therapy that comprises upper limb (UL) and cognitive training within the context of meaningful physical activity. The proposed study aims to compare the efficacy of Mitii™ to usual care to improve ADL motor and processing skills, gross motor capacity, UL and executive functioning in a randomised waitlist controlled trial.

METHODS/DESIGN

Sixty independently ambulant children (30 in each group) at least 12 months post ABI will be recruited to participate in this trial. Children will be matched in pairs at baseline and randomly allocated to receive either 20 weeks of Mitii™ training (30 min per day, six days a week, with a potential total dose of 60 h) immediately, or be waitlisted for 20 weeks. Outcomes will be assessed at baseline, immediately post-intervention and at 20 weeks post-intervention. The primary outcomes will be the Assessment of Motor and Process Skills and 30 s repetition maximum of functional strength exercises (sit-to-stand, step-ups and half kneel to stand). Measures of body structure and functions, activity, participation and quality of life will assess the efficacy of Mitii™ across all domains of the International Classification of Functioning, Disability and Health framework. A subset of children will undertake three tesla (3T) magnetic resonance imaging scans to evaluate functional neurovascular changes, structural imaging, diffusion imaging and resting state functional connectivity before and after intervention.

DISCUSSION

Mitii™ provides an alternative approach to deliver intensive therapy for children with an ABI in the convenience of the home environment. If Mitii™ is found to be effective, it may offer an accessible and inexpensive intervention option to increase therapy dose.

Medicare rebate for specialist medical practitioners from physiotherapy referrals: analysis of the potential impact on the Australian healthcare system

Abstract

OBJECTIVE

To identify and examine the likely impact on referrals to specialist medical practitioners, cost to government and patient out-of-pocket costs by providing a rebate under the Medicare Benefits Scheme to patients who attend a specialist medical practitioner upon referral direct from a physiotherapist.

METHODS

A model was constructed to synthesise the costs and benefits of referral with a rebate. Data to inform the model was obtained from administrative sources and from a direct survey of physiotherapists.

RESULTS

Given that six referrals per month are made by physiotherapists for a specialist consultation, allowing direct referral to medical specialists and providing patients with a Medicare rebate would result in a likely cost saving to the government ofup to $13 million per year. A range of sensitivity analyses were conducted with all scenarios resulting in some cost savings.

CONCLUSIONS

The impact of the proposed policy shift to allow direct referral of patients by physiotherapists to specialist medical practitioners and provide patients with a Medicare rebate would be cost saving.

The cost-effectiveness and consumer acceptability of taxation strategies to reduce rates of overweight and obesity among children in Australia: study protocol

BACKGROUND

Childhood obesity is a recognised public health problem and around 25% of Australian children are overweight or obese. A major contributor is the obesogenic environment which encourages over consumption of energy dense nutrient poor food. Taxation is commonly proposed as a mechanism to reduce consumption of poor food choices and hence reduce rates of obesity and overweight in the community.

METHODS/DESIGN

An economic model will be developed to assess the lifetime benefits and costs to a cohort of Australian children by reducing energy dense nutrient poor food consumption through taxation mechanisms. The model inputs will be derived from a series of smaller studies. Food options for taxation will be derived from literature and expert opinion, the acceptability and impact of price changes will be explored through a Citizen's Jury and a discrete choice experiment and price elasticities will be derived from the discrete choice experiment and consumption data.

DISCUSSION

The health care costs of managing rising levels of obesity are a challenge for all governments. This study will provide a unique contribution to the international knowledge base by engaging a variety of robust research techniques, with a multidisciplinary focus and be responsive to consumers from diverse socio-economic backgrounds.

A break-even analysis of delivering a memory clinic by videoconferencing

We analysed the costs of two kinds of dementia clinic. In the conventional clinic, held in a rural area, the specialist travels to the clinic from the city. In the videoconferencing clinic, patients are also seen in a rural area, but the specialist conducts the assessment by video from the city. The fixed costs common to both modalities, such as clinic infrastructure, were ignored. The total fixed cost of a monthly conventional clinic was $522 and the total fixed cost of a monthly videoconferencing clinic was $881. The additional variable cost of the specialist travelling to the conventional clinic was $2.62 per minute of the specialist's travelling time. The break-even point at which the cost of the two modalities is the same was just over two hours (138 min round trip). A sensitivity analysis showed that the break-even point was not particularly sensitive to changes in staff wages, but slightly more sensitive to the non labour costs of videoconferencing. Air travel is not an efficient alternative to travel by car. Reducing the number of clinics to six per year results in a much higher cost of running the videoconferencing service compared to the conventional service. Videoconferencing for the purpose of diagnosing dementia is both a reliable and cost effective method of health service provision when a specialist is required to drive for more than about two hours (round trip) to provide a memory disorder clinic service.

Quality of life of older frail persons receiving a post-discharge program

Background

A 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.

Methods

A 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.

Results

The 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.

Conclusions

A 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.

Using staffing ratios for workforce planning: evidence on nine allied health professions

BACKGROUND

Modern 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.

METHODS

A 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.

RESULTS

Twelve 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.

CONCLUSION

The evidence for use of staffing ratios for allied health practitioners is scarce and lags behind the fields of nursing and medicine.

Can post-acute care programmes for older people reduce overall costs in the health system? A case study using the Australian Transition Care Programme

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.

Factors associated with quality of life and caregiver strain amongst frail older adults referred to a community rehabilitation service: implications for service delivery

PURPOSE

To identify factors contributing to reduced quality of life and increased caregiver strain in an older population referred to a community rehabilitation team and to recommend service delivery models.

METHODS

Analytical cross-sectional study arising from baseline assessments from 107 subjects drawn from a randomised controlled trial of community rehabilitation service delivery models.

SETTING

A community rehabilitation team based in Brisbane, Queensland, Australia.

MEASURES

Primary outcome variables include quality of life (EQ-5D & VAS) and Carer Strain Index. Predictor variables include participation in functional activities, history of falls, number of medications, number of co-morbidities, depression, environmental hazards, physical function and nutrition. Association between variables assessed using linear regression.

RESULTS

Major factors contributing to reduced quality of life were having reduced participation in daily activities, depression, and having poor vision. Having poor nutrition and no longer driving also contributed to poor quality of life. The major factor contributing to increased caregiver strain was reduced participation in daily activities by the older person.

CONCLUSIONS

Community rehabilitation services working with older populations must adopt models of care that screen for and address a wide range of factors that contribute to poor quality of life and caregiver strain.

Randomized trial of domiciliary versus center-based rehabilitation: which is more effective in reducing falls and improving quality of life in older fallers?

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.
