Aims Heart failure (HF) nurse practitioners (NPs) are an important part of the HF specialist team, and their impact on the cost-effectiveness of their role is unknown. The aim of this study was to determine the cost-effectiveness of a HF NP inpatient service compared with current practice of no HF NP service from a health system perspective at 12 months and 3 years. Methods and results We developed a Markov model to estimate costs, effects, and cost-effectiveness for hospitalized HF patients and seen by a HF NP service compared with usual care at 12 months and 3 years. Costs and effects were taken from a retrospective observational cohort study. Transition probabilities and utilities were derived from published studies. A total of 500 patients were included (250 patients in the HF NP service vs. 250 patients in usual care). Average age was 77.7 ± 11 years, and 54% were male. At 12 months, the HF NP group was cheaper and more effective compared with no HF NP [$23 031 vs. $25 111 (AUD), respectively; quality-adjusted life years (QALYs) were 0.68 in HF NP group compared with 0.66 in usual care]. The incremental cost-effectiveness ratio showed a savings of $109 474 per QALY gained at 12 months and a savings of $270 667 per QALY gained at 3 years in favour of the HF NP service. Conclusion The HF NP service was cost-effective with lower costs and higher QALYs compared with no HF NP service. Economic evaluations alongside randomized controlled trials are warranted.

Background Globally the burden of heart failure is rising. Hospitalisation is one of the main contributors to the burden of heart failure and unfortunately, the majority of heart failure patients will experience multiple hospitalisations over their lifetime. Considering the high health care cost associated with heart failure, a review of economic evaluations of post-discharge heart failure services is warranted. Aim An integrated review of the economic evaluations of post-discharge nurse-led heart failure services for patients hospitalised with acute heart failure. Methods Electronic databases were searched using EBSCOHost: CINAHL complete, Medline complete, Embase, Scopus, EconLit, Global Health, and Health source (Consumer and Nursing/Academic) for published articles until 22nd June 2021. The searches focussed on papers that examined the cost-effectiveness of nurse-led clinics or telemonitoring involving nurses to follow-up patients after hospitalisation for acute heart failure. GRADE criteria and CHEERS checklist were used to determine the quality of the evidence and the quality of reporting of the economic evaluation. Results Out of 453 studies identified, eight studies were included: four in heart failure clinics and four in telemonitoring programs. Five of the articles were cost-effectiveness analyses, one a cost comparison and two studies involved economic modelling The GRADE criteria were rated as high in five studies. In which, four studies examined the cost-effectiveness of telemonitoring programs. Based on the CHEERS checklist for reporting quality of economic evaluations, the majority of economic evaluations were rated between 86 and 96%. All the studies found the intervention to be cost-effective compared to usual care with Incremental Cost Effectiveness Ratios ranging from $18 259 (Canadian dollars)/life year gained to €40,321 per Quality Adjusted Life Years gained. Conclusion Nurse-led heart failure clinics and telemonitoring programs were found to be cost-effective. Certainly, this review has shown that heart failure clinics and telemonitoring programs do represent value for money with their greatest impact and cost savings through reducing rehospitalisations.

Background Older Australians make up 46% of all potentially preventable hospitalisations (PPHs) and people living with dementia are at significantly greater risk. While policy reforms aim to reduce PPHs, there is currently little evidence available on what drives this, especially for people living with dementia. This study examines patterns of PPHs in people living with dementia to inform service delivery and the development of evidence-based interventions. Methods We used the Victorian Admitted Episodes Dataset from Victoria, Australia, to extract data for people aged 50 and over with a diagnosis of dementia between 2015 and 2016. Potentially avoidable admissions, known as ambulatory care sensitive conditions (ACSCs), were identified. The chi-square test was used to detect differences between admissions for ACSCs and non-ACSCs by demographic, geographical, and administrative factors. Predictors of ACSCs admissions were analysed using univariate and multiple logistic regression. Results Of the 8156 hospital records, there were 3884 (48%) ACSCs admissions, of which admissions for urinary tract infections accounted for 31%, followed by diabetes complications (21%). Mean bed-days were 8.26 for non-ACSCs compared with 9.74 for ACSCs (p ≤ 0.001). There were no differences between admissions for ACSCs and non-ACSCs by sex, marital status, region (rural vs metro), and admission source (private accommodation vs residential facility). Culture and language predicted ASCS admission rates in the univariate regression analyses, with ACSC admission rates increasing by 20 and 29% if English was not the preferred language or if an interpreter was required, respectively. Results from the multiple regression analysis confirmed that language was a significant predictor of ACSC admission rates. Conclusions Improved primary health care may help to reduce the most common causes of PPHs for people living with dementia, particularly for those from culturally and linguistically diverse backgrounds.

Background Long waiting times are associated with public community outpatient health services. This trial aimed to determine if a new model of care based on evidence-based strategies that improved patient flow in two small pilot trials could be used to reduce waiting time across a variety of services. The key principle of the Specific Timely Appointments for Triage (STAT) model is that patients are booked directly into protected assessment appointments and triage is combined with initial management as an alternative to a waiting list and triage system. Methods A stepped wedge cluster randomised controlled trial was conducted between October 2015 and March 2017, involving 3116 patients at eight sites across a major Australian metropolitan health network. Results The intervention reduced waiting time to first appointment by 33.8% (IRR = 0.663, 95% CI 0.516 to 0.852, P = 0.001). Median waiting time decreased from a median of 42 days (IQR 19 to 86) in the control period to a median of 24 days (IQR 13 to 48) in the intervention period. A substantial reduction in variability was also noted. The model did not impact on most secondary outcomes, including time to second appointment, likelihood of discharge by 12 weeks and number of appointments provided, but was associated with a small increase in the rate of missed appointments. Conclusions Broad-scale implementation of a model of access and triage that combined triage with initial management and actively managed the relationship between supply and demand achieved substantial reductions in waiting time without adversely impacting on other aspects of care. The reductions in waiting time are likely to have been driven, primarily, by substantial reductions for those patients previously considered low priority.

Summary In this study of 695 Australian older adults (aged ≥50 years), we found that men and women had a similar trajectory of health-related quality of life (HRQoL) recovery following fragility fracture at any skeletal site. These results provide us with critical knowledge that improves our understanding of health outcomes post-fracture. Introduction Mortality is higher in men than that in women following a fragility fracture, but it is unclear whether recovery of patient-reported outcomes such as health-related quality of life (HRQoL) differs between sexes. This study aimed to identify sex differences in HRQoL recovery 12 months post-fracture. Methods Data were from the Australian arm of the International Costs and Utilities Related to Osteoporotic Fractures Study (AusICUROS). Participants recruited to AusICUROS were adults aged ≥50 years who sustained a fragility fracture. HRQoL was measured using the EQ-5D-3L at three time-points post-fracture: within 2 weeks (including pre-fracture recall) and at 4 and 12 months. Multivariate logistic regression analyses were undertaken, adjusting for confounders including age, education, income, and healthcare utilization post-fracture. Results Overall, 695 AusICUROS participants (536 women, 77.1%) were eligible for analysis with fractures at the hip (n = 150), distal forearm (n = 261), vertebrae (n = 61), humerus (n = 52), and other skeletal sites (n = 171). At the time of fracture, men were younger, reported a higher income, and were more likely to be employed, compared with women. For all fracture sites combined, there were no differences between men and women in recovery to pre-fracture HRQoL at 12-month follow-up (adjusted OR = 1.09; 95% CI: 0.75–1.61). When stratified by fracture site, no significant sex differences were seen for hip (OR = 1.02; 95% CI: 0.42–2.52), distal forearm (OR = 1.60; 95% CI: 0.68–3.78), vertebral (OR = 2.28; 95% CI: 0.61–8.48), humeral (OR = 1.62; 95% CI: 0.16–9.99), and other fractures (OR = 1.00; 95% CI: 0.44–2.26). Conclusion Community-dwelling men and women who survived the 12 months following fragility fracture had a similar trajectory of HRQoL recovery at any skeletal site.

IntroductionPreliminary evidence suggests that progressive resistance training may be beneficial for people with Prader-Willi Syndrome (PWS), a rare genetic condition that results in muscle weakness and low muscle tone.To establish whether community-based progressive resistance training is effective in improving the muscle strength of people with PWS; to determine cost-effectiveness; and, to complete a process evaluation assessing intervention fidelity, exploring mechanisms of impact, understanding participant experiences and identifying contextual factors affecting implementation.Methods and analysisA multisite, randomised controlled trial will be completed. Sixty participants with PWS will be randomised to receive either progressive resistance training (experimental) or non-progressive exercise (placebo control). Participants will be aged 13 to 60 years, be able to follow simple instructions in English and have no contraindications to performing progressive resistance training. The experimental group will complete progressive resistance training two times weekly for 24 weeks supervised by an exercise professional at a community gym. The control group will receive all aspects of the intervention except progressive overload. Outcomes will be assessed at week 25 (primary endpoint) and week 52 by a blinded assessor. The primary outcome is muscle strength assessed using one repetition maximum for upper limb and lower limb. Secondary outcomes are muscle mass, functional strength, physical activity, community participation, health-related quality of life and behaviour. Health economic analysis will evaluate cost-effectiveness. Process evaluation will assess safety and intervention fidelity, investigate mechanism of impact, explore participant experiences and identify contextual factors affecting implementation. Data collection commenced in February 2020 and will conclude in September 2023.Ethics and disseminationEthical approval was obtained from The Royal Children’s Hospital Human Research Ethics Committee (HREC/50874/RCHM-2019) under the National Mutual Acceptance initiative. Research governance approvals were obtained from five clinical sites. Results will be disseminated through published manuscripts, conference presentations, public seminars and practical resources for stakeholder groups.Trial registration numberACTRN12620000416998; Australian and New Zealand Clinical Trial Registry.

IntroductionEndometriosis is a debilitating chronic inflammatory condition highly burdensome to the healthcare system. The present trial will establish the efficacy of (1) yoga and (2) cognitive–behavioural therapy (CBT), above (3) education, on quality of life, biopsychosocial outcomes and cost-effectiveness.Methods and analysisThis study is a parallel randomised controlled trial. Participants will be randomly allocated to yoga, CBT or education. Participants will be English-speaking adults, have a diagnosis of endometriosis by a qualified physician, with pain for at least 6 months, and access to internet. Participants will attend 8 weekly group CBT sessions of 120 min; or 8 weekly group yoga sessions of 60 min; or receive weekly educational handouts on endometriosis. The primary outcome measure is quality of life. The analysis will include mixed-effects analysis of variance and linear models, cost–utility analysis from a societal and health system perspective and qualitative thematic analysis.Ethics and disseminationEnrolment in the study is voluntary and participants can withdraw at any time. Participants will be given the option to discuss the study with their next of kin/treating physician. Findings will be disseminated via publications, conferences and briefs to professional organisations. The University’s media team will also be used to further disseminate via lay person articles and media releases.Trial registration numberACTRN12620000756921p; Pre-results.

Background Chronic diseases contribute to a significant proportion (71%) of all deaths each year worldwide. Governments and other stakeholders worldwide have taken various actions to tackle the key risk factors contributing to the prevalence and impact of chronic diseases. Private health insurers (PHI) are one key stakeholders, particularly in Australian health system, and their engagement in chronic disease prevention is growing. Therefore, we investigated the impacts of chronic disease prevention interventions implemented by PHI both in Australia and internationally. Method We searched multiple databases (Business Source Complete, CINAHL, Global Health, Health Business Elite, Medline, PsycINFO, and Scopus) and grey literature for studies/reports published in English until September 2020 using search terms on the impacts of chronic disease prevention interventions delivered by PHIs. Two reviewers assessed the risk of bias using a quality assessment tool developed by Effective Public Healthcare Panacea Project. After data extraction, the literature was synthesised thematically based on the types of the interventions reported across studies. The study protocol was registered in PROSPERO, CRD42020145644. Results Of 7789 records, 29 studies were eligible for inclusion. There were predominantly four types of interventions implemented by PHIs: Financial incentives, health coaching, wellness programs, and group medical appointments. Outcome measures across studies were varied, making it challenging to compare the difference between the effectiveness of different intervention types. Most studies reported that the impacts of interventions, such as increase in healthy eating, physical activity, and lower hospital admissions, last for a shorter term if the length of the intervention is shorter. Interpretation Although it is challenging to conclude which intervention type was the most effective, it appeared that, regardless of the intervention types, PHI interventions of longer duration (at least 2 years) were more beneficial and outcomes were more sustained than those PHI interventions that lasted for a shorter period. Funding Primary source of funding was Geelong Medical and Hospital Benefits Association (GMHBA), an Australian private health insurer.

Background Specific Timely Appointments for Triage (STAT) is an intervention designed to reduce waiting time in community outpatient health services, shown to be effective in a large stepped wedge cluster randomised controlled trial. STAT combines initial strategies to reduce existing wait lists with creation of a specific number of protected appointments for new patients based on demand. It offers an alternative to the more traditional methods of demand management for these services using waiting lists with triage systems. This study aimed to explore perceptions of clinicians and administrative staff involved in implementing the model. Method Semi-structured interviews with 20 staff members who experienced the change to STAT were conducted by an independent interviewer. All eight sites involved in the original trial and all professional disciplines were represented in the sample. Data were coded and analysed thematically. Results Participants agreed that shorter waiting time for patients was the main advantage of the STAT model, and that ongoing management of caseloads was challenging. However, there was variation in the overall weight placed on these factors, and therefore the participants’ preference for the new or previous model of care. Perceptions of whether the advantages outweighed the disadvantages were influenced by five sub-themes: staff perception of how much waiting matters to the patient, prior exposure to the management of waiting list, caseload complexity, approach and attitude to the implementation of STAT and organisational factors. Conclusions The STAT model has clear benefits but also presents challenges for staff members. The findings of this study suggest that careful preparation and management of change and active planning for known fluctuations in supply and demand are likely to help to mitigate sources of stress and improve the likelihood of successful implementation of the STAT model for improving waiting times for patients referred to community outpatient services.

Osteoporosis and osteopenia are increasingly prevalent conditions among older adults. Not only do the fractures associated with poor bone health have significant health consequences for the individual, but also their economic impact is placing increasing financial burden on governments and society. This study aimed to determine the direct economic cost of osteoporosis, osteopenia, and fractures among Australians aged 50 years and older in 2017. This study uses previous Australian data on the incidence and prevalence of osteoporosis and osteopenia together with recent Australian data on health service utilization after fracture to provide an estimate of the economic burden of osteoporosis. A bottom-up costing approach was used to determine the average direct health care and non-health care total costs of a fracture, as well as the average community health service costs of managing individuals with osteoporosis or osteopenia. The total direct cost of osteoporosis in Australia in 2017 was estimated to be $3.44 billion (AUD 2017, USD 2.77 billion). Treatment of fractures accounted for 68% of total direct costs, and non-fracture management of osteoporosis accounted for 32%. Hip fractures accounted for the highest proportion (43%) of the total direct cost of fractures, although fractures at "other" sites accounted for 38.5%. Fractures among individuals aged 70 years and older accounted for 74% of the direct costs (55% and 19% in women and men, respectively). Fracture costs in those with osteopenia accounted for 50% of direct fracture treatment costs. This up-to-date cost analysis estimated that costs in 2017 were three times higher than in 2007. These estimates will aid clinicians, policy makers, researchers, and health care organizations to acknowledge the economic importance of reducing osteoporosis-related fractures and associated costs. This provides a strong public health case to promote bone health that will assist in reducing future fracture-related costs. © 2018 American Society for Bone and Mineral Research.

IntroductionCommunity-dwelling people recovering from hip fracture have the physical capacity to walk in their community but lack the confidence to do so. The primary aim of this trial is to determine whether motivational interviewing increases time spent walking at 12 months in community-dwelling people after hip fracture compared with an attention placebo control group. Secondary aims are to evaluate cost effectiveness, patient and health service outcomes and to complete a process evaluation.Methods and analysisAn assessor-blinded parallel group randomised controlled design with embedded health economic evaluation and process evaluation will compare the effects of n=270 participants randomly allocated to an experimental group (motivational interviewing) or a control group (dietary advice). For inclusion, participants are aged ≥65 years, living at home independently within 6 months of discharge from hospital after hip fracture and able to walk independently and communicate with conversational English. Key exclusion criteria are severe depression or anxiety, impaired intellectual functioning and being medically unstable to walk. Participants allocated to the experimental group will receive 10 (8 weekly and 2 booster) telephone-based sessions of motivational interviewing to increase walking over 16 weeks. Participants allocated to the control group will receive an equivalent dose of telephone-based dietary advice. The primary outcome is daily time spent walking over 7 days assessed at weeks 0, 9, 26 and 52. Secondary outcomes include measures of psychological-related function, mobility-related function, community participation, health-related quality of life and falls. Health service utilisation and associated costs will be assessed. Process evaluation will assess the fidelity of the motivational interviewing intervention and explore contextual factors through semistructured interviews.Ethics and disseminationEthical approval obtained from Eastern Health (E19-002), Peninsula Health (50261/EH-2019), Alfred Health (617/20) and La Trobe University (E19/002/50261). The findings will be disseminated in peer-reviewed journals, conference presentations and public seminars.Trial registration numberACTRN12619000936123.

BackgroundMost hospitals use physiological signs to trigger an urgent clinical review. We investigated whether facilitation could improve nurses’ vital sign measurement, interpretation, treatment and escalation of care for deteriorating patients.MethodsIn a pragmatic cluster randomised controlled trial, we randomised 36 inpatient wards at four acute hospitals to receive standard clinical practice guideline (CPG) dissemination to ward staff (n=18) or facilitated implementation for 6 months following standard dissemination (n=18). Expert, hospital and ward facilitators tailored facilitation techniques to promote nurses’ CPG adherence. Patient records were audited pre-intervention, 6 and 12 months post-intervention on randomly selected days. Escalation of care as per hospital policy was the primary outcome at 6 and 12 months after implementation. Patients, nurses and assessors were blinded to group assignment. Analysis was by intention-to-treat.ResultsFrom 10 383 audits, improved escalation as per hospital policy was evident in the intervention group at 6 months (OR 1.47, 95% CI (1.06 to 2.04)) with a complete set of vital sign measurements sustained at 12 months (OR 1.22, 95% CI (1.02 to 1.47)). There were no significant differences in escalation of care as per hospital policy between study groups at 6 or 12 months post-intervention. After adjusting for patient and hospital characteristics, a significant change from T0 in mean length of stay between groups at 12 months favoured the intervention group (−2.18 days, 95% CI (−3.53 to –0.82)).ConclusionMulti-level facilitation significantly improved escalation as per hospital policy at 6 months in the intervention group that was not sustained at 12 months. The intervention group had increased vital sign measurement by nurses, as well as shorter lengths of stay for patients at 12 months. Further research is required to understand the dose of facilitation required to impact clinical practice behaviours and patient outcomes.Trial registration numberACTRN12616000544471p

Summary Background HIV/AIDS causes significant socioeconomic burden to affected households and individuals, which is exacerbated by non-communicable diseases (NCDs). The Asia Pacific Region (APR) comprises about 60% of the global population and has been significantly affected by HIV/AIDS with 5.8 million after Sub-Saharan Africa in 2019. We investigated socioeconomic impacts of HIV/AIDS alone and the added burden of NCDs on HIV-affected households (HIV-HHs) and individuals in the APR. Method We searched multiple databases for studies published in English over 30 years on socioeconomic impact of HIV/AIDS alone and HIV/AIDS with NCDs on affected households or individuals in APR. Findings were synthesised across six domains: employment, health-related expenditure, non-health expenditure, strategies for coping with household liabilities, food security, and social protection. Findings HIV-HHs had a significantly higher socioeconomic burden compared to Non-HIV households. Total household expenditure was lower in HIV-HHs but with higher expenditure on health services. HIV-HHs experienced more absenteeism, lower wages, higher unemployment, and higher food insecurity. There is a paucity of evidence on the added burden of NCDs on HIV-HHs with only a single study from Myanmar. Interpretation Understanding the socioeconomic impact of HIV/AIDS with and without NCD is important. The evidence indicates that HIV-HHs in APR suffer from a significantly higher socioeconomic burden than Non-HIV-HHs. However, evidence on the additional burden of NCDs remains scarce and more studies are needed to understand the joint socioeconomic impact of HIV/AIDS and NCDs on affected households.

Objective To update a previous review on whether additional physical therapy services reduce length of stay, improve health outcomes, and are safe and cost-effective for patients with acute or subacute conditions. Data Sources Electronic database (AMED, CINAHL, EMBASE, MEDLINE, Physiotherapy Evidence Database [PEDro], PubMed) searches were updated from 2010 through June 2017. Study Selection Randomized controlled trials evaluating additional physical therapy services on patient health outcomes, length of stay, or cost-effectiveness were eligible. Searching identified 1524 potentially relevant articles, of which 11 new articles from 8 new randomized controlled trials with 1563 participants were selected. In total, 24 randomized controlled trials with 3262 participants are included in this review. Data Extraction Data were extracted using the form used in the original systematic review. Methodological quality was assessed using the PEDro scale, and the Grading of Recommendation Assessment, Development, and Evaluation approach was applied to each meta-analysis. Data synthesis Postintervention data were pooled with an inverse variance, random-effects model to calculate standardized mean differences (SMDs) and 95% confidence intervals (CIs). There is moderate-quality evidence that additional physical therapy services reduced length of stay by 3 days in subacute settings (mean difference [MD]=–2.8; 95% CI, –4.6 to –0.9; I2=0%), and low-quality evidence that it reduced length of stay by 0.6 days in acute settings (MD=–0.6; 95% CI, –1.1 to 0.0; I2=65%). Additional physical therapy led to small improvements in self-care (SMD=.11; 95% CI, .03–.19; I2=0%), activities of daily living (SMD=.13; 95% CI, .02–.25; I2=15%), and health-related quality of life (SMD=.12; 95% CI, .03–.21; I2=0%), with no increases in adverse events. There was no significant change in walking ability. One trial reported that additional physical therapy was likely to be cost-effective in subacute rehabilitation. Conclusions Additional physical therapy services improve patient activity and participation outcomes while reducing hospital length of stay for adults. These benefits are likely safe, and there is preliminary evidence to suggest they may be cost-effective.

ObjectivesTimely access to outpatient services is a major issue for public health systems. To address this issue, we aimed to establish the return on investment to the health system of the implementation of an alternative model for access and triage (Specific Timely Appointments for Triage: STAT) compared with a traditional waitlist model.DesignUsing a prospective pre–post design, an economic analysis was completed comparing the health system costs for participants who were referred for community outpatient services post-implementation of STAT with a traditional waitlist comparison group.SettingEight community outpatient services of a health network in Melbourne, Australia.ParticipantsAdults and children referred to community outpatient services.InterventionsSTAT combined targeted activities to reduce the existing waiting list and direct booking of patients into protected assessment appointments. STAT was compared with usual care, in which new patients were placed on a waiting list and offered appointments as space became available.OutcomesHealth system costs included STAT implementation costs, outpatient health service use, emergency department presentations and hospital admissions 3 months before and after initial outpatient appointment. Waiting time was the primary outcome. Incremental cost-effectiveness ratios (ICERs) were estimated from the health system perspective.ResultsData from 557 participants showed a 16.9 days or 29% (pConclusionsThere was a significant reduction in waiting time with the introduction of STAT at minimal cost to the health system.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12615001016527).

Background: Vital signs are the primary indicator of physiological status and for determining the need for urgent clinical treatment. Yet, if physiological signs of deterioration are missed, misinterpreted or mismanaged, then critical illness, unplanned intensive care admissions, cardiac arrest and death may ensue. Although evidence demonstrates the benefit of early recognition and management of deteriorating patients, failure to escalate care and manage deteriorating patients remains a relatively frequent occurrence in hospitals. Methods/design: A pragmatic cluster-randomised controlled trial design will be used to measure clinical effectiveness and cost of a facilitation intervention to improve nurses' vital sign measurement, interpretation, treatment and escalation of care for patients with abnormal vital signs. A cost consequence analysis will evaluate the intervention cost and effectiveness, and a process evaluation will determine how the implementation of the intervention contributes to outcomes. We will compare clinical outcomes and costs from standard implementation of clinical practice guidelines (CPGs) to facilitated implementation of CPGs. The primary outcome will be adherence to the CPGs by nurses, as measured by escalation of care as per organisational policy. The study will be conducted in four Australian major metropolitan teaching hospitals. In each hospital, eight to ten wards will be randomly allocated to intervention and control groups. Control wards will receive standard implementation of CPGs, while intervention wards will receive standard CPG implementation plus facilitation, using facilitation methods and processes tailored to the ward context. The intervention will be administered to all nursing staff at the ward level for 6 months. At each hospital, two types of facilitators will be provided: a hospital-level facilitator as the lead; and two ward-level facilitators for each ward. Discussion: This study uses an innovative, networked approach to facilitation to enable uptake of CPGs. Findings will inform the intervention utility and knowledge translation measurement approaches. If successful, the study methodology and intervention has potential for translation to other health care standards.

Purpose: To test whether the Functional Independence Measure (FIM) could be mapped to the EQ-5D-3L to give researchers a viable but “second-best” option for calculating quality-adjusted life-years (QALYs) and conducting a cost-utility analysis when only clinical outcomes have been collected. Materials and methods: Secondary analysis of repeated measures data collected during a randomized controlled trial (n = 3506 observations) at two inpatient rehabilitation centres. Participants had a mean age of 74 (SD 13) years, 63% were women and 58% were admitted with an orthopaedic diagnosis. Ordinary least-squares regression and adjusted limited dependent variable mixture models were used to estimate regression-based mappings. Performance was evaluated based on mean absolute error and the proportion of errors in excess of the minimally important difference. Results: In orthopaedic and neurological patients, high mean absolute errors (0.2 on the quality-adjusted life years scale) and a high proportion of errors (60%) in excess of the minimally important difference suggest that predicted EQ-5D-3L values provided a poor substitute for observed EQ-5D-3L values. Conclusions: Regression-based mappings from the FIM to the EQ-5D-3L are error-prone and unsuitable for calculating QALYs in rehabilitation patients. Researchers and rehabilitation professionals should therefore include a multi-attribute utility instrument such as the EQ-5D as well as the FIM to evaluate the effect of rehabilitation interventions and in rehabilitation registries. This will provide additional information on health-related quality of life and support cost-utility analyses.Implications for rehabilitationThe Functional Independence Measure (FIM) cannot be used to calculate quality-adjusted life-years (QALYs) for cost-utility analyses.Predicting QALYs from FIM data is a poor substitute for direct measurement of QALYs in orthopaedic or neurological rehabilitation populations.Multi-attribute utility instruments (MAUIs) allow direct measurement of QALYs, as well as providing a patient-reported measure of clinical quality and outcomes in rehabilitation.A MAUI should be included routinely in clinical practice by rehabilitation professionals as well as in rehabilitation trials and registries to track patient outcomes and improve clinical practice.

Background Falls remain common for community-dwelling older people and impose a substantial economic burden to the healthcare system. RESPOND is a novel falls prevention programme that aims to reduce secondary falls and fall injuries among older people who present to a hospital emergency department (ED) with a fall. The present protocol describes a prospective economic evaluation examining the incremental cost-effectiveness of the RESPOND programme, compared with usual care practice, from the Australian health system perspective. Methods and design This economic evaluation will recruit 528 participants from two major tertiary hospital EDs in Australia and will be undertaken alongside a multisite randomised controlled trial. Outcome and costing data will be collected for all participants over the 12-month trial. It will compare the RESPOND falls prevention programme with usual care practice (current community-based falls prevention practices) to determine its incremental cost-effectiveness according to three intermediate clinical outcomes: (1) falls prevented, (2) fall injuries prevented and (3) injurious falls prevented. In addition, utilities will be derived from a generic quality-of-life measure (EQ-5D-5L) and used to calculate the ‘incremental cost per quality-adjusted life years gained’. Discussion The results of this study will provide healthcare decision makers with evidence to assist with setting spending thresholds for preventive health programmes and inform selection of emergency and community service models of care.

This study aimed to evaluate the effectiveness of a telephone health coaching and support service provided to members of an Australian private health insurance fund-Telephonic Complex Care Program (TCCP)-on hospital use and associated costs. A case-control pre-post study design was employed using propensity score matching. Private health insurance members (n=273) who participated in TCCP between April and December 2012 (cases) were matched (1:1) to members who had not previously been enrolled in the program or any other disease management programs offered by the insurer (n=232). Eligible members were community dwelling, aged ≥65 years, and had 2 or more hospital admissions in the 12 months prior to program enrollment. Preprogram variables that estimated the propensity score included: participant demographics, diagnoses, and hospital use in the 12 months prior to program enrollment. TCCP participants received one-to-one telephone support, personalized care plan, and referral to community-based services. Control participants continued to access usual health care services. Primary outcomes were number of hospital admission claims and total benefits paid for all health care utilizations in the 12 months following program enrollment. Secondary outcomes included change in total benefits paid, hospital benefits paid, ancillary benefits paid, and total hospital bed days over the 12 months post enrollment. Compared with matched controls, TCCP did not appear to reduce health care utilization or benefits paid in the 12 months following program enrollment. However, program characteristics and implementation may have impacted its effectiveness. In addition, challenges related to evaluating complex health interventions such as TCCP are discussed.

Background To evaluate the effectiveness of audit and communication strategies to reduce diagnostic errors made by clinicians. Methods MEDLINE complete, CINHAL complete, EMBASE, PSNet and Google Advanced. Electronic and manual search of articles on audit systems and communication strategies or interventions, searched for papers published between January 1990 and April 2017. We included studies with interventions implemented by clinicians in a clinical environment with real patients. Results A total of 2431 articles were screened of which 26 studies met inclusion criteria. Data extraction was conducted by two groups, each group comprising two independent reviewers. Articles were classified by communication (6) or audit strategies (20) to reduce diagnostic error in clinical settings. The most common interventions were delivered as technology-based systems n = 16 (62%) and within an acute care setting n = 15 (57%). Nine studies reported randomised controlled trials. Three RCT studies on communication interventions and 3 RCTs on audit strategies found the interventions to be effective in reducing diagnostic errors. Conclusion Despite numerous studies on interventions targeting diagnostic errors, our analyses revealed limited evidence on interventions being practically used in clinical settings and a bias of studies originating from the US (n = 19, 73% of included studies). There is some evidence that trigger algorithms, including computer based and alert systems, may reduce delayed diagnosis and improve diagnostic accuracy. In trauma settings, strategies such as additional patient review (e.g. trauma teams) reduced missed diagnosis and in radiology departments review strategies such as team meetings and error documentation may reduce diagnostic error rates over time. Trial registration The systematic review was registered in the PROSPERO database under registration number CRD42017067056.

Despite the increasing number of older people, many with cognitive impairment (CI), in hospitals, there is yet to be an evaluation of hospital-wide interventions improving the management of those with CI. In hospitalized patients with CI, there are likely to be associations between increased complications that impact on outcomes, length of stay, and costs. This prospective study will evaluate the effectiveness of an established hospital CI support program on patient outcomes, patient quality of life, staff awareness of CI, and carer satisfaction. Using a stepped-wedge, continuous-recruitment method, the pre-intervention patient data will provide the control data for usual hospital care. The intervention, the Dementia Care in Hospitals Program, provides hospital-wide CI awareness and support education, and screening for all patients aged 65+, along with a bedside alert, the Cognitive Impairment Identifier. The primary outcome is a reduction in hospital-acquired complications: urinary tract infections, pressure injuries, pneumonia and delirium. Secondary outcome measures include cost effectiveness, patient quality of life, carer satisfaction, staff awareness of CI, and staff perceived impact of care. This large-sample study across four sites offers an opportunity for research evaluation of health service functioning at a whole-of-hospital level, which is important for sustainable change in hospital practice.

IntroductionThe aim of this study was to assess the impact of home-based telehealth monitoring on health outcomes, quality of life and costs over 12 months for patients with diabetes and/or chronic obstructive pulmonary disease (COPD) who were identified as being at high risk of readmission to hospital.MethodsThis pilot study was a randomised controlled trial combined with an economic analysis to examine the outcomes of standard care versus home-based telehealth for people with diabetes and/or COPD who were at risk of hospital readmission within one year. The primary outcomes were (i) hospital admission and length of stay (LOS); and (ii) health-related quality of life (HRQOL); and the secondary outcomes were (i) health-related clinical outcomes; (ii) anxiety and depression scores; and (iii) health literacy. The costs of the intervention and hospitalisations were included.ResultsA total of 86 and 85 participants were randomised to the intervention and control groups respectively. The difference between groups in hospital LOS was –3.89 (95% confidence interval (CI): –9.40, 1.62) days, and for HRQOL, 0.09 (95% CI: 0.05, 0.14) in favour of the telehealth monitoring group. There was a saving of AUD$6553 (95% CI: –12145, –961) in the cost of hospitalisation over 12 months, which offset the increased cost of tele-monitoring. The intervention group showed an improvement in anxiety, depression and health literacy at 12 months, and in the diabetes group, a reduction in microalbuminuria.DiscussionThe telehealth monitoring intervention improved patient's health outcomes and quality of life at no additional cost.

Background. Falls are common and disabling in people with Parkinson’s disease (PD). There is a need to quantify the effects of movement rehabilitation on falls in PD. Objective. To evaluate 2 physical therapy interventions in reducing falls in PD. Methods. We randomized 210 people with PD to 3 groups: progressive resistance strength training coupled with falls prevention education, movement strategy training combined with falls prevention education, and life-skills information (control). All received 8 weeks of out-patient therapy once per week and a structured home program. The primary end point was the falls rate, recorded prospectively over a 12 month period, starting from the completion of the intervention. Secondary outcomes were walking speed, disability, and quality of life. Results. A total of 1547 falls were reported for the trial. The falls rate was higher in the control group compared with the groups that received strength training or strategy training. There were 193 falls for the progressive resistance strength training group, 441 for the movement strategy group and 913 for the control group. The strength training group had 84.9% fewer falls than controls (incidence rate ratio [IRR] = 0.151, 95% CI 0.071-0.322, P < .001). The movement strategy training group had 61.5% fewer falls than controls (IRR = 0.385, 95% CI 0.184-0.808, P = .012). Disability scores improved in the intervention groups following therapy while deteriorating in the control group. Conclusions. Rehabilitation combining falls prevention education with strength training or movement strategy training reduces the rate of falls in people with mild to moderately severe PD and is feasible.

Aspirin is generally associated with prevention of cardiovascular events. However, observational studies report associations between low grade inflammation, bone remodelling and fracture risk1.

Questions For people with idiopathic Parkinson's disease, does a 6-week, comprehensive, home exercise program reduce falls and disability and improve health-related quality of life? Is the program cost-effective? Design Randomised, controlled trial with concealed allocation and assessor blinding. Participants One hundred and thirty-three community-dwelling adults with Parkinson's disease. Intervention The experimental group completed a 6-week home program comprising progressive resistance strength training, movement strategy training and falls education. The control group completed 6 weeks of non-specific life skills training. Participants in both groups received weekly therapist-guided sessions for 6 consecutive weeks and a weekly self-directed home program. Outcome measures The primary outcome was the rate of falls, documented for the 12-month period immediately after therapy. Secondary outcomes were disability and health-related quality of life, assessed before and after intervention and at a 12-month follow-up. Results A total of 2255 falls were reported by the 12-month follow-up. The proportion of fallers in the experimental and control groups was 61 and 72%, respectively, which was not statistically significantly different (RR=0.85, 95% CI 0.66 to 1.09). There was no significant between-group difference in the rate of falls (incidence rate ratio=1.58, 95% CI 0.73 to 3.43). A survival analysis of participant time to first fall did not show a significant between-group difference (log-rank test χ 2 =0.79, p =0.37). No significant between-group differences occurred for mobility, disability or quality of life. The mean cost of delivering the experimental intervention was AUD1596. Conclusion A home program of strength and movement strategy training and falls education does not prevent falls when applied at the dose used in this study. Arguably, the dosage of therapy was insufficient. Future trials need to explore further therapy content, repetitions and duration, in order to optimise outcomes and cost-effectiveness. [Morris ME, Taylor NF, Watts JJ, Evans A, Horne M, Kempster P, Danoudis M, McGinley J, Martin C, Menz HB (2017) A home program of strength training, movement strategy training and education did not prevent falls in people with Parkinson's disease: a randomised trial.

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.

Objective: To investigate if a Saturday rehabilitation service in addition to usual care improved return to work outcomes 12 months post discharge and to report predictors of return to work. Design: Subgroup analysis of a single-blind randomized controlled trial. Setting: General inpatient rehabilitation service. Subjects: A mixed cohort of 137 adults previously engaged in work, who were admitted for inpatient rehabilitation and allocated to a control group ( n=63) or an intervention group (n=74). Intervention: The control group received usual care rehabilitation from Monday to Friday and the intervention group received usual care plus an additional rehabilitation service on Saturdays (physiotherapy and occupational therapy). Main outcome: Return to paid or unpaid work. Results: After 12 months, 36 participants (57%) in the control group and 38 participants (51%) in the intervention group had returned to work. There was no difference between groups (mean difference -1.06 hours per week, 95% CI -8.70 to 6.57) in return to work outcomes. Functional status on discharge (OR 1.05, 95%CI 1.00 to 1.10), an orthopaedic diagnosis (OR 4.92, 95%CI 2.01 to 12.03) and engagement in unpaid work prior to rehabilitation (OR 5.08, 95%CI 1.39 to 18.58) were predictive of return to work at 12 months. Conclusion: A Saturday rehabilitation service in addition to usual care showed no improvement in return to work outcomes at 12 months. Predictors of return to work may help identify those at risk of not returning to work and who require follow-up vocational rehabilitation services.

Waiting lists for treatment are common in outpatient and community services, Existing methods for managing access and triage to these services can lead to inequities in service delivery, inefficiencies and divert resources from frontline care. Evidence from two controlled studies indicates that an alternative to the traditional “waitlist and triage” model known as STAT (Specific Timely Appointments for Triage) may be successful in reducing waiting times without adversely affecting other aspects of patient care. This trial aims to test whether the model is cost effective in reducing waiting time across multiple services, and to measure the impact on service provision, health-related quality of life and patient satisfaction. A stepped wedge cluster randomised controlled trial has been designed to evaluate the impact of the STAT model in 8 community health and outpatient services. The primary outcome will be waiting time from referral to first appointment. Secondary outcomes will be nature and quantity of service received (collected from all patients attending the service during the study period and health-related quality of life (AQOL-8D), patient satisfaction, health care utilisation and cost data (collected from a subgroup of patients at initial assessment and after 12 weeks). Data will be analysed with a multiple multi-level random-effects regression model that allows for cluster effects. An economic evaluation will be undertaken alongside the clinical trial. This paper outlines the study protocol for a fully powered prospective stepped wedge cluster randomised controlled trial (SWCRCT) to establish whether the STAT model of access and triage can reduce waiting times applied across multiple settings, without increasing health service costs or adversely impacting on other aspects of patient care. If successful, it will provide evidence for the effectiveness of a practical model of access that can substantially reduce waiting time for outpatient and community services with subsequent benefits for both efficiency of health systems and patient care.

Questions: Among people receiving inpatient rehabilitation after stroke, does additional weekend physiotherapy and/or occupational therapy reduce the length of rehabilitation hospital stay compared to those who receive a weekday-only service, and does this change after controlling for individual factors? Does additional weekend therapy improve the ability to walk and perform activities of daily living, measured at discharge? Does additional weekend therapy improve health-related quality of life, measured 6 months after discharge from rehabilitation? Which individual, clinical and hospital characteristics are associated with shorter length of rehabilitation hospital stay? Design: This study pooled individual data from two randomised, controlled trials (n=350) using an individual patient data meta-analysis and multivariate regression. Participants: People with stroke admitted to inpatient rehabilitation facilities. Intervention: Additional weekend therapy (physiotherapy and/or occupational therapy) compared to usual care (5 days/week therapy). Outcome measures: Length of rehabilitation hospital stay, independence in activities of daily living measured with the Functional Independence Measure, walking speed and health-related quality of life. Results: Participants who received weekend therapy had a shorter length of rehabilitation hospital stay. In the un-adjusted analysis, this was not statistically significant (MD –5.7 days, 95% CI –13.0 to 1.5). Controlling for hospital site, age, walking speed and Functional Independence Measure score on admission, receiving weekend therapy was significantly associated with a shorter length of rehabilitation hospital stay (β=7.5, 95% CI 1.7 to 13.4, p =0.001). There were no significant between-group differences in Functional Independence Measure scores (MD 1.9 points, 95% CI –2.8 to 6.6), walking speed (MD 0.06 m/second, 95% CI –0.15 to 0.04) or health-related quality of life (SMD –0.04, 95% CI –0.26 to 0.19) at discharge. Discussion: Modest evidence indicates that additional weekend therapy might reduce rehabilitation hospital length of stay. Clinical Trial Registration: ACTRN12610000096055, ACTRN12609000973213.

Telephone-based disease management (DM) programs can improve health outcomes and provide a positive return on investment to funders. However, there is scant evidence about how to use hospital admission episode data to identify patients who are most likely to participate in a DM program. The objective of this study was to use hospital admission episode data held by health insurers to determine those factors that predict members with chronic disease joining and remaining in a DM program for at least 6 months. A multivariable logistic regression model was constructed to determine predictors of participating in a DM program for an insured population who had been admitted to hospital for congestive heart failure, coronary artery disease, or chronic obstructive pulmonary disease. The outcome variable was binary: did the member both opt into the DM program and remain in the program for at least 6 months? The study population included 9874 private health fund members. Time from a related hospital admission was a significant predictor, with those offered the program within 3 to 6 months being 71% more likely (95% confidence interval [CI]: 33%, 113%) to participate. The length of time from offer to commencement also was a significant predictor, with those commencing within 3 to 4 months being 75% (95% CI: 44%, 112%) as likely to remain in the program. It is possible to predict which individuals are most likely to participate in a telephone-based DM program using hospital admission episode data. Once individuals are identified, timely commencement of a DM program is an important predictor of success.

To identify the demographic factors, impairments and activity limitations that contribute to health-related quality of life (HRQOL) in people with idiopathic Parkinson’s disease (PD). Two hundred and ten individuals with idiopathic PD who participated in the baseline assessment of a randomized clinical trial were included. The Parkinson’s Disease Questionnaire-39 summary index was used to quantify HRQOL. In order to provide greater clarity regarding the determinants of HRQOL, path analysis was used to explore the relationships between the various predictors in relation to the functioning and disability framework of the International Classification of Functioning model. The two models of HRQOL that were examined in this study had a reasonable fit with the data. Activity limitations were found to be the strongest predictor of HRQOL. Limitations in performing self-care activities contributed the most to HRQOL in Model 1 (β = 0.38; p

PurposeThe purpose of this paper is to determine how Australian workplaces, their managers and employees respond to those who are grieving at work, as a result of chronic or terminal illness, or caring for those with chronic or terminal illness. The review draws on Australian and relevant international literature and seeks to answer this question.Design/methodology/approachA literature review was undertaken in preparation for an Australian study examining workplace supports for people who are grieving – because they are carers, have experienced a death, or are balancing their own illness with their work. Using a range of search terms, the literature was searched for relevant work between 1980 and 2010. The search found examples of workplace supports throughout the world and some developing Australian literature.FindingsDespite illness and death occurring at any stage of a person's life, there is little research that identifies workplace issues associated with grief and loss. And while workplace legislation allows for minimal supports, there was evidence that some workplaces have begun to offer flexibility for work life balance.Practical implicationsEffective workplace supports will involve individual and workplace responses, but also require legislative approaches in order to effect broad‐based system change.Originality/valueThe paper compares Australian and international literature about workplace supports and provides an overview of the issues arising.

Objectives Wait lists are common in ambulatory and community-based services. The aim of the present study was to explore managers’ perceptions of factors that contribute to wait times. Methods A qualitative study was conducted using semi-structured interviews with managers and team leaders of ambulatory and community health services within a large health network. Interviews were transcribed and coded, and the codes were then grouped into themes and subthemes. Results Representatives from 26 services participated in the project. Four major themes were identified. Three themes related to reasons and factors contributing to increased wait time for services (inefficient intake and scheduling processes; service disruptions due to human resource issues; and high service demand). A fourth theme related to staff attitudes towards wait times and acceptance and acknowledgement of wait lists. Conclusions Service providers perceive high demand to be a key driver of wait times, but a range of other factors also contributes and may represent opportunities for improving access to care. These other factors include improving process efficiencies, greater consistency of service delivery through more efficient management of human resources and shifting to more consumer-centred approaches in measuring wait times in order to drive improvements in patient flow. What is known about the topic? Wait times are common in out-patient and ambulatory services. These services experience high demand, which is likely to continue to grow as health service delivery shifts from hospital to community settings. What does this paper add? Although demand is an important driver of wait times, there are other modifiable factors that also contribute, including process inefficiencies and service disruption related to human resource issues. An underlying staff attitude of acceptance of wait times appears to be an additional barrier to improving access. What are the implications for practitioners? The findings of the present study suggest that there are opportunities for improving access to ambulatory and community health services through more efficient use of existing resources. However, a more consumer-focused approach regarding acceptability of wait times is needed to help drive change.

Background Our previous work showed that providing additional rehabilitation on a Saturday was cost effective in the short term from the perspective of the health service provider. This study aimed to evaluate if providing additional rehabilitation on a Saturday was cost effective at 12 months, from a health system perspective inclusive of private costs. Methods Cost effectiveness analyses alongside a single-blinded randomized controlled trial with 12 months follow up inclusive of informal care. Participants were adults admitted to two publicly funded inpatient rehabilitation facilities. The control group received usual care rehabilitation services from Monday to Friday and the intervention group received usual care plus additional Saturday rehabilitation. Incremental cost effectiveness ratios were reported as cost per quality adjusted life year (QALY) gained and for a minimal clinical important difference (MCID) in functional independence. Results A total of 996 patients [mean age 74 years (SD 13)] were randomly assigned to the intervention (n = 496) or control group (n = 500). The intervention was associated with improvements in QALY and MCID in function, as well as a non-significant reduction in cost from admission to 12 months (mean difference (MD) AUD$6,325; 95% CI −4,081 to 16,730; t test p = 0.23 and MWU p = 0.06), and a significant reduction in cost from admission to 6 months (MD AUD$6,445; 95% CI 3,368 to 9,522; t test p = 0.04 and MWU p = 0.01). There is a high degree of certainty that providing additional rehabilitation services on Saturday is cost effective. Sensitivity analyses varying the cost of informal carers and self-reported health service utilization, favored the intervention. Conclusions From a health system perspective inclusive of private costs the provision of additional Saturday rehabilitation for inpatients is likely to have sustained cost savings per QALY gained and for a MCID in functional independence, for the inpatient stay and 12 months following discharge, without a cost shift into the community.
