RESUMO
BACKGROUND: Comprehensive national joint replacement registries with well-validated data offer unique opportunities for examining the potential future burden of hip and knee osteoarthritis (OA) at a population level. This study aimed to forecast the burden of primary total knee (TKR) and hip replacements (THR) performed for OA in Australia to the year 2030, and to model the impact of contrasting obesity scenarios on TKR burden. METHODS: De-identified TKR and THR data for 2003-2013 were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Population projections and obesity trends were obtained from the Australian Bureau of Statistics, with public and private hospital costs sourced from the National Hospital Cost Data Collection. Procedure rates were projected according to two scenarios: (1) constant rate of surgery from 2013 onwards; and (2) continued growth in surgery rates based on 2003-2013 growth. Sensitivity analyses were used to estimate future TKR burden if: (1) obesity rates continued to increase linearly; or (2) 1-5% of the overweight or obese population attained a normal body mass index. RESULTS: Based on recent growth, the incidence of TKR and THR for OA is estimated to rise by 276% and 208%, respectively, by 2030. The total cost to the healthcare system would be $AUD5.32 billion, of which $AUD3.54 billion relates to the private sector. Projected growth in obesity rates would result in 24,707 additional TKRs totalling $AUD521 million. A population-level reduction in obesity could result in up to 8062 fewer procedures and cost savings of up to $AUD170 million. CONCLUSIONS: If surgery trends for OA continue, Australia faces an unsustainable joint replacement burden by 2030, with significant healthcare budget and health workforce implications. Strategies to reduce national obesity could produce important TKR savings.

BACKGROUND: Many people with advanced dementia live in residential aged care homes. Care home staff need the knowledge and skills to provide high-quality end-of-life (EOL) dementia care. However, several studies have found EOL dementia care to be suboptimal, and care staff have reported they would benefit from training in palliative care and dementia. Simulation offers an immersive learning environment and has been shown to improve learners' knowledge and skills. However, there is little research on simulation training for residential care staff. This article presents the development and evaluation protocol of IMproving Palliative care Education and Training Using Simulation in Dementia (IMPETUS-D) - a screen-based simulation training program on palliative dementia care, targeted at residential care staff. IMPETUS-D aims to improve the quality of palliative care provided to people living with dementia in residential care homes, including avoiding unnecessary transfers to hospital. METHODS: A cluster RCT will assess the effect of IMPETUS-D. Twenty-four care homes (clusters) in three Australian cities will be randomised to receive either the IMPETUS-D intervention or usual training opportunities (control). The primary outcome is to reduce transfers to hospital and deaths in hospital by 20% over 6-months in the intervention compared to the control group. Secondary outcomes include uptake of goals of care plans over 6 and 12 months, change in staff knowledge and attitudes towards palliative dementia care over 6 months, change in transfers to hospital and deaths in hospital over 12 months. For the primary analysis logistic regression models will be used with standard errors weighted by the cluster effects. A mixed methods process evaluation will be conducted alongside the cluster RCT to assess the mechanisms of impact, the implementation processes and contextual factors that may influence the delivery and effects of the intervention. DISCUSSION: In Australia, the need for high-quality advanced dementia care delivered in residential aged care is growing. This study will assess the effect of IMPETUS-D a new simulation-based training program on dementia palliative and EOL care. This large multisite trial will provide robust evidence about the impact of the intervention. If successful, it will be distributed to the broader residential care sector.

Objective: to profile the trajectory of, and risk factors for, functional decline in older patients in the 30 days following Emergency Department (ED) discharge. Methods: prospective cohort study of community-dwelling patients aged ≥65 years, discharged home from a metropolitan Melbourne ED, 31 July 2012 to 30 November 2013. The primary outcome was functional decline, comprising either increased dependency in personal activities of daily living (ADL) or in skills required for living independently instrumental ADL (IADL), deterioration in cognitive function, nursing home admission or death. Univariate analyses were used to select risk factors and logistic regression models constructed to predict functional decline. Results: at 30 days, 34.4% experienced functional decline; with 16.7% becoming more dependent in personal ADL, 17.5% more dependant in IADL and 18.4% suffering deterioration in cognitive function. Factors independently associated with decline were functional impairment prior to the visit in personal ADL (Odds Ratio [OR] 3.21, 95% confidence interval [CI] 2.26-4.53) or in IADL (OR 6.69, 95% CI 4.31-10.38). The relative odds were less for patients with moderately impaired cognition relative to those with normal cognition (OR 0.38, 95% CI 0.19-0.75). There was a 68% decline in the relative odds of functional decline for those with any impairment in IADL who used an aid for mobility (OR 0.32, 95% CI 0.14-0.7). Conclusion: older people with pre-existing ADL impairment were at high risk of functional decline in the 30 days following ED presentation. This effect was largely mitigated for those who used a mobility aid. Early intervention with functional assessments and appropriate implementation of support services and mobility aids could reduce functional decline after discharge.

BACKGROUND: When tested in a randomized controlled trial (RCT) of 31,411 patients, the nurse-led 6-PACK falls prevention program did not reduce falls. Poor implementation fidelity (i.e., program not implemented as intended) may explain this result. Despite repeated calls for the examination of implementation fidelity as an essential component of evaluating interventions designed to improve the delivery of care, it has been neglected in prior falls prevention studies. This study examined implementation fidelity of the 6-PACK program during a large multi-site RCT. METHODS: Based on the 6-PACK implementation framework and intervention description, implementation fidelity was examined by quantifying adherence to program components and organizational support. Adherence indicators were: 1) falls-risk tool completion; and for patients classified as high-risk, provision of 2) a 'Falls alert' sign; and 3) at least one additional 6-PACK intervention. Organizational support indicators were: 1) provision of resources (executive sponsorship, site clinical leaders and equipment); 2) implementation activities (modification of patient care plans; training; implementation tailoring; audits, reminders and feedback; and provision of data); and 3) program acceptability. Data were collected from daily bedside observation, medical records, resource utilization diaries and nurse surveys. RESULTS: All seven intervention components were delivered on the 12 intervention wards. Program adherence data were collected from 103,398 observations and medical record audits. The falls-risk tool was completed each day for 75% of patients. Of the 38% of patients classified as high-risk, 79% had a 'Falls alert' sign and 63% were provided with at least one additional 6-PACK intervention, as recommended. All hospitals provided the recommended resources and undertook the nine outlined program implementation activities. Most of the nurses surveyed considered program components important for falls prevention. CONCLUSIONS: While implementation fidelity was variable across wards, overall it was found to be acceptable during the RCT. Implementation failure is unlikely to be a key factor for the observed lack of program effectiveness in the 6-PACK trial. TRIAL REGISTRATION: The 6-PACK cluster RCT is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12611000332921 (29 March 2011).

BACKGROUND: an emergency department (ED) visit is a sentinel event for an older person, with increased likelihood of adverse outcomes post-discharge including early re-presentation. OBJECTIVES: to determine factors associated with early re-presentation. METHODS: prospective cohort study conducted in the ED of a large acute Melbourne tertiary hospital. Community-dwelling patients ≥65 years were interviewed including comprehensive assessment of cognitive and functional status, and mood. Logistic regression was used to identify risk factors for return within 30 days. RESULTS: nine hundred and fifty-nine patients, median age 77 years, were recruited. One hundred and forty patients (14.6%) re-presented within 30 days, including 22 patients (2.3%) on ≥2 occasions and 75 patients (7.8%) within 7 days. Risk factors for re-presentation included depressive symptoms, cognitive impairment, co-morbidity, triaged as less urgent (ATS 4) and attendance in the previous 12 months, with a decline in risk after 85 years of age. Logistic regression identified chronic obstructive pulmonary disease (OR 1.78, 95% CI 1.02-3.11), moderate cognitive impairment (OR 2.07, 95% CI 1.09-3.90), previous ED visit (OR 2.11, 95% CI 1.43-3.12) and ATS 4 (OR 2.34, 95% CI 1.10-4.99) as independent risk factors for re-presentation. Age ≥85 years was associated with reduced risk (OR 0.81, 95% CI 0.70-0.93). CONCLUSION: older discharged patients had a high rate of early re-presentation. Previously identified risk factors-increased age, living alone, functional dependence and polypharmacy-were not associated with early return in this study. It is not clear whether these inconsistencies represent a change in patient case-mix or strategies implemented to reduce re-attendance. This remains an important area for future research.

BACKGROUND: Inhospital falls cause morbidity, staff burden and increased healthcare costs. It is unclear if the persistent problem of inhospital falls is due to the use of ineffective interventions or their suboptimal implementation. The 6-PACK programme appears to reduce fall injuries and a randomised controlled trial (RCT) was undertaken to confirm effects. This paper describes the protocol for the preimplementation studies that aimed to identify moderators of the effective use of the 6-PACK programme to inform the development of an implementation plan to be applied in the RCT. METHODS: The 6-PACK project included five preimplementation studies: (1) a profile of safety climate; (2) review of current falls prevention practice; (3) epidemiology of inhospital falls; (4) acceptability of the 6-PACK programme; and (5) barriers and enablers to implementation of the 6-PACK programme. The Theoretical Domain Framework that includes 12 behaviour change domains informed the design of these studies that involved 540 staff and 8877 patients from 24 wards from six Australian hospitals. Qualitative and quantitative methods were applied with data collected via: structured bedside observation; daily nurse unit manager verbal report of falls; audit of medical records, incident reporting and hospital administrative data; surveys of ward nurses; focus groups with ward nurses; and key informant interviews with senior staff. DISCUSSION: Information on contextual, system, intervention, patient and provider level factors is critical to the development of an implementation plan. Information gained from these studies was used to develop a plan applied in the RCT that addressed the barriers and harnessed enablers. TRIAL REGISTRATION NUMBER: The RCT is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12611000332921.

OBJECTIVE: To evaluate the feasibility of Pilates exercise in older people to decrease falls risk and inform a larger trial. DESIGN: Pilot Randomized controlled trial. SETTING: Community physiotherapy clinic. PARTICIPANTS: A total of 53 community-dwelling people aged ⩾60 years (mean age, 69.3 years; age range, 61-84). INTERVENTIONS: A 60-minute Pilates class incorporating best practice guidelines for exercise to prevent falls, performed twice weekly for 12 weeks. All participants received a letter to their general practitioner with falls risk information, fall and fracture prevention education and home exercises. MAIN OUTCOME MEASURES: Indicators of feasibility included: acceptability (recruitment, retention, intervention adherence and participant experience survey); safety (adverse events); and potential effectiveness (fall, fall injury and injurious fall rates; standing balance; lower limb strength; and flexibility) measured at 12 and 24 weeks. RESULTS: Recruitment was achievable but control group drop-outs were high (23%). Of the 20 participants who completed the intervention, 19 (95%) attended ⩾75% of the classes and reported classes were enjoyable and would recommend them to others. The rate of fall injuries at 24 weeks was 42% lower and injurious fall rates 64% lower in the Pilates group, however, was not statistically significant (P = 0.347 and P = 0.136). Standing balance, lower-limb strength and flexibility improved in the Pilates group relative to the control group (P < 0.05). Estimates suggest a future definitive study would require 804 participants to detect a difference in fall injury rates. CONCLUSION: A definitive randomized controlled trial analysing the effect of Pilates in older people would be feasible and is warranted given the acceptability and potential positive effects of Pilates on fall injuries and fall risk factors. TRIAL REGISTRATION: The protocol for this study is registered with the Australian and New Zealand Clinical Trials Registry (ACTRN1262000224820).

BACKGROUND: a decline in health state and re-attendance are common in people aged ≥65 years following emergency department (ED) discharge. Diverse care models have been implemented to support safe community transition. This review examined ED community transition strategies (ED-CTS) and evaluated their effectiveness. METHODS: a systematic review and meta-analysis using multiple databases up to December 2013 was conducted. We assessed eligibility, methodological quality, risk of bias and extracted published data and then conducted random effects meta-analyses. Outcomes were unplanned ED representation or hospitalisation, functional decline, nursing-care home admission and mortality. RESULTS: five experimental and four observational studies were identified for qualitative synthesis. ED-CTS included geriatric assessment with referral for post-discharge community-based assistance, with differences apparent in components and delivery methods. Four studies were included in meta-analysis. Compared with usual care, the evidence indicates no appreciable benefit for ED-CTS for unplanned ED re-attendance up to 30 days (odds ratio (OR) 1.32, 95% confidence interval (CI) 0.99-1.76; n = 1,389), unplanned hospital admission up to 30 days (OR 0.90, 95% CI 0.70-1.16; n = 1,389) or mortality up to 18 months (OR 1.04, 95% CI 0.83-1.29; n = 1,794). Variability between studies precluded analysis of the impact of ED-CTS on functional decline and nursing-care home admission. CONCLUSIONS: there is limited high-quality data to guide confident recommendations about optimal ED community transition strategies, highlighting a need to encourage better integration of researchers and clinicians in the design and evaluation process, and increased reporting, including appropriate robust evaluation of efficacy and effectiveness of these innovative models of care.

OBJECTIVES: Health care professionals (HCPs) caring for people with primary malignant glioma (PMG) and their carers see many of the profound challenges facing this group, yet their perspectives are not documented. This study aimed to understand and document the unique perspective of HCPs in relation to the supportive and palliative care needs of patients with PMG and their carers, with a view to developing a model of care. METHODS: Qualitative study involving semi-structured focus groups and interviews with 35 medical, nursing and allied health staff actively engaged in providing care for this patient group. Purposive and theoretical sampling from two major metropolitan hospitals and one community palliative care service in Australia was utilised to seek perspectives from a variety of disciplines and health care settings. Thematic analysis was conducted by three independent researchers, using a constant comparative method influenced by grounded theory. RESULTS: Key themes relating to the needs of people with PMG which were apparent from the HCPs included: The difference in the illness course of glioma compared to other cancers; Limitations of current medical care; Challenges in balancing hope with reality of the illness; and Recommendations to improve care, including recognising the role of family and moving from a model where services are offered in response to demonstrated needs. Significance of the results: Current models of care based upon the classic cancer trajectory are unresponsive to the needs of people with PMG. Care may be enhanced by moving towards a proactive approach, extending the goals of care beyond medical needs and broadening the focus of care to include family needs.

High-grade malignant glioma patients face a poor prognosis, preceded by rapid functional and neurobehavioural changes, making multidisciplinary care incorporating supportive and palliative care important. This study aimed to quantify the association between symptoms,receipt of supportive and palliative care and site of death. We undertook a retrospective cohort study between 2003 and 2009 of incident malignant glioma cases who survived for at least 120 days between their first hospitalisation and their death (n = 678) in Victoria, Australia, using linked hospital, emergency department and death data. The median age of patients was 62 years, 40% were female, and the median survival was 11 months. Twenty-six percent of patients died outside of hospital, 49% in a palliative care bed/hospice setting and 25% in an acute hospital bed. Patients having 1 or more symptoms were more than five times as likely to receive palliative care. Patients who receive palliative care are 1.7 times more likely to die outside of hospital. In conclusion malignant glioma patients with a high burden of symptoms are more likely to receive palliative care and, in turn, patients who receive palliative care are more likely to die at home.

Palliative care provision for patients with high-grade malignant glioma is often under-utilised. Difficulties in prognostication and inter-patient variability in survival may limit timely referral. This study sought to (1) describe the clinical presentation of short-term survivors of malignant glioma (survival time <120 days); (2) map their hospital utilisation, including palliative and supportive care service use, and place of death; (3) identify factors which may be important to serve as a prompt for palliative care referral. A retrospective cohort study of incident malignant glioma cases between 2003-2009 surviving <120 days in Victoria, Australia was undertaken (n = 482). Cases were stratified according to the patient's survival status (dead vs. alive) at the end of the diagnosis admission, and at 120 days from diagnosis. Palliative care was received by 78 % of patients who died during the diagnosis admission. Only 12 % of patients who survived the admission and then deteriorated rapidly dying in the following 120 days were referred to palliative care in their hospital admission, suggesting an important clinical subgroup that may miss out on being linked into palliative care services. The strongest predictor of death during the diagnosis admission was the presence of cognitive or behavioural symptoms, which may be an important prompt for early palliative care referral.

PURPOSE: Referral to supportive and palliative care services for people with high-grade primary malignant glioma (PMG) often occurs late in the illness course, despite significant care needs and overall poor prognosis. This study aimed to understand patient experience at the end of life and document supportive and palliative care needs. METHODS: A qualitative study was conducted involving ten PMG patients who were at different stages in the illness course including the end of life and had varying levels of physical and cognitive function. Consecutive, eligible patients attending neurosurgery, oncology, and palliative care services of two metropolitan hospitals were recruited. In-depth interviews explored supportive and palliative care needs across the disease trajectory. Interviews were analysed independently by three investigators consistent with a grounded theory approach, and emerging ideas were compared and refined to define key patient experiences. RESULTS: Despite the medical treatment and supportive care available, there remains a gap in services addressing complex existential and psychosocial needs that were markedly valued by patients. Patient experience was characterised by a pervasive loss of all that encompassed their former sense of self and a focus on immediate needs. CONCLUSIONS: Patients in this study had substantial needs, which were often not shared and not addressed by the current medical system of care. An improved multidisciplinary care model is indicated, which proactively (1) engages care coordination and advocacy; (2) minimises patients' sense of waiting and uncertainty through mapping out a plan, including involvement of palliative care in a timely fashion; and (3) actively invites discussion around goals and preferences for care to promote patients' sense of self.

PURPOSE: To determine whether Assessment of Quality of Life (AQoL) utility scores can be reliably estimated from Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in people with hip and knee joint disease (arthritis or osteoarthritis). METHODS: WOMAC and AQoL data were analysed from 219 people recruited for a national population-based study. Generalised linear models were used to estimate AQoL utility scores based on WOMAC total and subscale scores and personal characteristics. Goodness of fit was assessed for each model, and plots of prediction errors versus actual AQoL utility scores were used to gauge bias. RESULTS: Each model closely predicted the average AQoL utility score for the overall sample (actual mean AQoL 0.64, range of predicted means 0.63-0.64; actual median AQoL 0.71, range of predicted medians 0.68-0.69). No clear preferred model was identified, and overall, the models predicted 40-46% of the variance in AQoL utility scores. The WOMAC function subscale model performed similarly to the total score model. The models functioned best at the mid-range of AQoL scores, with greater bias observed for extreme scores. Inaccuracies in individual-level estimates and low/high health-related quality of life (HRQoL) subgroup estimates were evident. CONCLUSION: Reliable overall group-level estimates were produced, supporting the application of these techniques at a population level. Using WOMAC scores to predict individual AQoL utility scores is not recommended, and the models may produce inaccurate estimates in studies targeting patients with low/high HRQoL. Where pain and stiffness data are unavailable, the WOMAC function subscale can be used to generate a reasonable utility estimate.

PURPOSE: The aims of this study were to quantify the frequency of adverse outcomes after elective knee arthroscopies in Victoria, Australia, and to identify risk factors associated with adverse outcomes. METHODS: We performed a retrospective, longitudinal cohort study of elective orthopaedic admissions using the Victorian Admitted Episodes database, a routinely collected public and private hospital episodes database linked to death registry data, from July 1, 2000, to June 30, 2009. Adverse outcome measures included pulmonary embolism (PE), deep vein thrombosis (DVT), hemarthrosis, effusion and synovitis, cellulitis, wound infection, synovial fistula, acute renal failure, myocardial infarct, stroke, and death. Patients were excluded if they had an additional procedure performed during the arthroscopy admission. We identified complications during the admission and within readmissions up to 30 days after the procedure. PE, DVT, and death within 90 days of the arthroscopy episode were also examined. We used logistic regression analysis to identify risk factors associated with complications. RESULTS: After we excluded 16,807 patients (8.5%) with an additional procedure during their admission, there were 180,717 episodes involving an elective arthroscopy during the period studied. The most common adverse outcomes within 30 days were DVT (579, 0.32%), effusion and synovitis (154, 0.09%), PE (147, 0.08%), and hemarthrosis (134, 0.07%). The 30-day orthopaedic readmission rate was 0.77%, and there were 55 deaths (0.03%). Within 90 days of arthroscopy, we identified 655 events of DVT (0.36%) and 179 PE events (0.10%). Logistic regression analysis identified that potential risk factors for complications were older age, presence of comorbidity, being married, major mechanical issues, and having the procedure performed in a public hospital. CONCLUSIONS: Our study found 6.4 adverse outcomes per 1,000 elective knee arthroscopy procedures (0.64%), with the 3 most common complications being DVT, effusion and synovitis, and PE. We have also identified risk factors for adverse outcomes, particularly chronic kidney disease, myocardial infarction, cerebrovascular accident, and cancer. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

BACKGROUND: The Questionnaire on Palliative Care for Advanced Dementia (qPAD) is increasingly being used to assess residential aged care workers' knowledge and attitudes about palliative care for people with dementia. The qPAD developers performed an exploratory factor analysis and assessed the internal consistency using a small sample. AIM: The aim of this study was to further assess the structural validity of the qPAD using a large sample of qPAD responses from staff who work in residential aged care homes in Australia. METHODS: Data from 727 care staff who participated in an Australian dementia palliative care training project were used for exploratory factor analyses, assessment of internal consistency, and confirmatory factor analysis of the knowledge test and attitude scale components of the qPAD. RESULTS: The exploratory factor analysis of the knowledge test produced a four-factor solution. One item loaded weakly, and four items had cross-loadings. Factor labels for the knowledge test were difficult to define. Factor analysis of the attitude scale produced a three-factor structure with good internal consistency-Feeling valued and part of the care team (α = 0.88), Family and team engagement (α = 0.75) and Perceptions and beliefs (α = 0.83). Confirmatory factor analysis indicated improvements in model fit were needed for both the knowledge test and attitude scale. CONCLUSION: The findings of this factor analysis differed from the original study. The attitude scale produced a three-factor structure, but the knowledge test requires further development due to weak and cross-loadings of several items, inadequate internal consistency of factors and poor model fit.

OBJECTIVE: To assess the use of elective knee arthroscopy procedures for all adults 20 years and older, and for adults with a concomitant diagnosis of osteoarthritis (OA) in Victoria. DESIGN, SETTING AND PATIENTS: Retrospective, longitudinal cohort study of 807 030 elective orthopaedic admissions using routinely collected public and private hospital data from 1 July 2000 to 30 June 2009. MAIN OUTCOME MEASURE: Trends in rates of elective knee arthroscopy in the time period (defined as a statistically significant change in the incident rate ratio for each financial year with respect to the reference year). Subgroup analyses were undertaken for patients with an associated diagnosis of OA. RESULTS: There were 190 881 admissions for 159 528 patients having an elective knee arthroscopic procedure. There was a significant decrease in arthroscopic procedures from the 2000-01 financial year, after adjusting for growth in elective orthopaedic volume and relevant patient and hospital characteristics. The trend did not apply to patients with osteoarthritis of the knee. A significant shift in the use of multiday procedures undertaken in high volume, public hospital settings to same-day admissions in the private sector was also identified. CONCLUSIONS: The overall rate of elective knee arthroscopy in Victorian hospitals has decreased. There has been no sustained reduction in arthroscopy use for people with a concomitant diagnosis of OA, despite published evidence questioning the effectiveness of the procedures.

BACKGROUND: The need to improve patient safety has been identified as a major priority for health reform in developed countries, including Australia. We investigated the implementation and appropriateness of Variable Life Adjusted Displays as a quality control procedure to monitor "in-control" versus "out-of-control" processes in Victorian public hospitals. METHODS: Victorian Admitted Episode Data from Department of Human Services, Victoria for 2004-7 were used. The VLAD is a plot of a cumulative sum of the difference in expected outcome (range 0-1) and observed outcome (0 or 1) for sequential separations. Three outcomes were assessed: in-hospital mortality for acute myocardial infarction, stroke and heart failure. Logistic regression was used to obtain a realistic measure of expected mortality over the period 2004-5, adjusting for covariates and comorbidities, to estimate expected mortality risk for the separations between 2005-7. VLAD were plotted for the years 2005-7, by the 11 hospitals with the highest frequency of separations. Signalling limits for 30%, 50% and 75% risk decrease and risk increase were determined and plotted for each VLAD utilizing risk-adjusted cumulative sum techniques. This is a likelihood-ratio test statistic for signalling. If the VLAD signalled by intersecting with a limit, the limit was reset. RESULTS: The three logit models displayed reasonable fit to the observed data. There were n = 2999 separations in the AMI model, n = 3598 in the HF model and n = 1922 in the stroke model. The number of separations plotted by VLAD ranged from n = 126 to n = 648. No signals were observed in 64%, 55% and 18% of VLAD for AMI, HF and stroke respectively. For AMI and HF 9% of hospitals signalled at least once for each of 30%, 50% and 75% risk increase, whereas this was 45% for stroke. Hospitals signalling at least once for risk decrease ranged from 18% to 36% across the levels of risk and outcomes. No VLAD signalled for both risk decrease and increase. CONCLUSIONS: VLAD intersecting with limits to signal "out-of-control" states, may be an appropriate technique to help hospitals assess quality control. Preliminary work displays some between hospital differences. Relevant signals can be used to investigate why a system is potentially performing better than or worse than expected. Types and levels of investigation could depend on the type of signalling. Validation work, for example attempting to correlate signals with clinical notes, prior to VLAD distribution needs to be undertaken.

PURPOSE: The objective of this review was to critically appraise the literature relating to associations between high-level structural and operational hospital characteristics and improved performance. DATA SOURCES: The Cochrane Library, MEDLINE (Ovid), CINAHL, proQuest and PsychINFO were searched for articles published between January 1996 and May 2010. Reference lists of included articles were reviewed and key journals were hand searched for relevant articles. STUDY SELECTION: and data extraction Studies were included if they were systematic reviews or meta-analyses, randomized controlled trials, controlled before and after studies or observational studies (cohort and cross-sectional) that were multicentre, comparative performance studies. Two reviewers independently extracted data, assigned grades of evidence according to the Australian National Health and Medical Research Council guidelines and critically appraised the included articles. Data synthesis Fifty-seven studies were reported within 12 systematic reviews and 47 observational articles. There was heterogeneity in use and definition of performance outcomes. Hospital characteristics investigated were environment (incentives, market characteristics), structure (network membership, ownership, teaching status, geographical setting, service size) and operational design (innovativeness, leadership, organizational culture, public reporting and patient safety practices, information technology systems and decision support, service activity and planning, workforce design, staff training and education). The strongest evidence for an association with overall performance was identified for computerized physician order entry systems. Some evidence supported the associations with workforce design, use of financial incentives, nursing leadership and hospital volume. CONCLUSION: There is limited, mainly low-quality evidence, supporting the associations between hospital characteristics and healthcare performance. Further characteristic-specific systematic reviews are indicated.

BACKGROUND: Knee osteoarthritis (OA) is one of the most common and costly chronic musculoskeletal conditions world-wide and is associated with substantial pain and disability. Many people with knee OA also experience co-morbidities that further add to the OA burden. Uptake of and adherence to physical activity recommendations is suboptimal in this patient population, leading to poorer OA outcomes and greater impact of associated co-morbidities. This pragmatic randomised controlled trial will investigate the clinical- and cost-effectiveness of adding telephone coaching to a physiotherapist-delivered physical activity intervention for people with knee OA. METHODS/DESIGN: 168 people with clinically diagnosed knee OA will be recruited from the community in metropolitan and regional areas and randomly allocated to physiotherapy only, or physiotherapy plus nurse-delivered telephone coaching. Physiotherapy involves five treatment sessions over 6 months, incorporating a home exercise program of 4-6 exercises (targeting knee extensor and hip abductor strength) and advice to increase daily physical activity. Telephone coaching comprises 6-12 telephone calls over 6 months by health practitioners trained in applying the Health Change Australia (HCA) Model of Health Change to provide behaviour change support. The telephone coaching intervention aims to maximise adherence to the physiotherapy program, as well as facilitate increased levels of participation in general physical activity. The primary outcomes are pain measured by an 11-point numeric rating scale and self-reported physical function measured by the Western Ontario and McMaster Universities Osteoarthritis Index subscale after 6 months. Secondary outcomes include physical activity levels, quality-of-life, and potential moderators and mediators of outcomes including self-efficacy, pain coping and depression. Relative cost-effectiveness will be determined from health service usage and outcome data. Follow-up assessments will also occur at 12 and 18 months. DISCUSSION: The findings will help determine whether the addition of telephone coaching sessions can improve sustainability of outcomes from a physiotherapist-delivered physical activity intervention in people with knee OA. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry reference: ACTRN12612000308897.

OBJECTIVE: To examine the frequency of deaths in low-mortality diagnosis-related groups (LM-DRGs) and the patient and hospital characteristics associated with them. DESIGN, SETTING AND PATIENTS: Retrospective cohort study of 2,400,089 discharge episodes for adults (> 18 years) from 122 Victorian public hospitals from 1 July 2006 to 30 June 2008. MAIN OUTCOME MEASURES: Frequency of episodes of death in LM-DRGs (defined as DRGs with mortality < 0.5% over the previous 3 years or < 0.5% in any of the previous 3 years); associations between characteristics of patients and hospitals with deaths in LM-DRGs. RESULTS: There were 1,008, 816 LM-DRG episodes with 0-15 LM-DRG deaths per hospital in the 2006-07 financial year and 0-20 deaths per hospital in the 2007-08 financial year. Increased age, level of comorbidity, being male, admission from a residential aged care facility, interhospital transfer, emergency admission and lower hospital volume were associated with an increased risk of death in LM-DRG episodes in both years. Metropolitan location and teaching/major provider status were not associated with LM-DRG deaths (P > 0.10). More than 40% of LM-DRG deaths were among patients aged 83 years or over, who had a length of stay of less than 1 day and had a medical DRG classification. Standardised mortality ratios (SMRs) that adjusted for the patient and hospital characteristics identified nine outlier hospitals with high frequencies of deaths in LM-DRGs in the 2006-07 and six in the 2007-08 financial year compared with 59 hospitals flagged by the death-in-LM-DRG indicator. CONCLUSIONS: The use of the LM-DRG indicator requires further investigation to test its validity. LM-DRG deaths are infrequent, making it difficult to identify temporal changes and outlier hospitals. Patient characteristics unrelated to quality of care increase the likelihood of death among LM-DRG patients. The SMR analysis showed that failure to adjust for these characteristics may result in unfair and inaccurate identification of outlier hospitals. The increased risk of death associated with interhospital transfer patients and low-volume hospitals requires further investigation.
