To evaluate the simultaneous moderating role of sleep duration and screen time in the relationship between waist circumference (WC) and clustered cardiometabolic risk score (cMetS) according to children and adolescents' physical activity. A cross‐sectional study was conducted on 3072 children and adolescents (aged 6–17 years, 57.5% girls). Physical activity, sleep duration, and screen time were assessed through a self‐report questionnaire. The cMetS was determined by averaging the z‐scores of risk factors and dividing it by four. Moderation analyses were tested through multiple linear regression models. Among physically active individuals, sleep duration (p = 0.85) and screen time (p = 0.96) had no influence on the relationship between WC and cMetS. However, a positive interaction between WC x screen time and cMetS (p = 0.04) was observed for physically inactive participants. Concerning sleep duration, there was no interaction with WC. Participants who spent 60 min of screen time presented lower cMetS, even presenting high WC, compared to the higher tertiles of screen time (180 and 360 min). However, although the interaction between sleep duration and WC was not significant, it was observed that the lowest tertile of sleep duration (482 min) combined with 60 min of screen time presented lower cMetS even with the presence of high WC. Our findings encourage compliance with physical activity guidelines associated with the adoption of adequate screen time to minimize the influence of waist circumference on cMetS. Highlights: Sleep duration and screen time influence adiposity and cardiometabolic risk in physically inactive children and adolescents;Meeting the PA guidelines seems crucial in preventing cardiometabolic risk factors;In inactive individuals, the screen has a deleterious effect on cardiometabolic health.

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.

The aim of the present study was to verify whether the amount of sleep duration, screen time, and physical activity moderate the relationship between FTO rs9939609 polymorphism and waist circumference (WC) in children and adolescents. This is a cross-sectional study conducted with 1338 children and adolescents, aged between 6 and 17 years. Lifestyle habits were assessed through self-reported questionnaire. WC was measured on the narrowest part of the trunk between the last rib and the iliac crest. FTO rs9939609 polymorphism was genotyped by real time polymerase chain reaction. The PROCESS macro for the SPSS was used for moderation analyses, through multiple linear regression models. Results indicated significant interactions were found between sleep duration and screen time X FTO rs9939609, showing that these lifestyle behaviours are moderators in the relationship between a genetic predisposition for obesity and higher WC. For physical activity, there was no significant interaction. Therefore, sleeping more than 564 min a day (i.e. 9.4 h) and spending no more than 233 min in front of screen may counteract the genetic predisposition to obesity in children and adolescents. Highlights A healthy lifestyle may counteract the genetic predisposition to central obesity; Children and adolescents should sleep more than approximately 9 h (564 min) per day and spend less than approximately 4 h (233 min) per day in front of screens in order to counteract the genetic predisposition to central obesity conferred by the FTO gene variant. It is fundamental to promote actions for the adoption of a healthy lifestyle, including the importance of presenting adequate sleep habits and low screen time for a better cardiometabolic health and reduction of obesity.

Objective: The goal of this study was to analyze whether the relationship between the rs9939609 polymorphism of the fat mass and obesity‐associated gene (FTO) with nutritional status is moderated by the ponderal index (PI) at birth in children and adolescents. Methods: A cross‐sectional study evaluated 382 schoolchildren aged 6–17 years. Anthropometric variables such as waist circumference (WC), body mass index (BMI) and body fat percentage (BF%) were used to assess nutritional status. Weight and height at birth were used for the PI calculation, which was divided into tertiles (lower, middle and upper). To compare the continuous variables between genotypes of the rs9939609 polymorphism, a recessive model (TT/AT vs. AA) and covariance analysis (ANCOVA) were used. Results: The AA genotype of the rs9939609 polymorphism was associated with higher WC in schoolchildren born with lower PI (β = 4.40; p =.048). However, for BF%, the genotype association was found in the upper PI tertile (β = 7.35; p =.040). Conclusion: The relationship between WC and BF% with rs9939609 polymorphism (FTO) seems to be moderated by PI at birth. This is an important insight, since the data for intrauterine growth, genetic factors and the presence of obesity in children and adolescents are still contradictory. [ABSTRACT FROM AUTHOR]

This study analyzed the associations between the 24‐hour movement behaviors composition and fitness in preschoolers and investigated predicted changes in fitness when time in active behaviors is reallocated. This cross‐sectional study was carried out with 270 preschoolers (132 boys; 3.97 ± 0.80 years‐old). Light and moderate‐to‐vigorous physical activity (LPA and MVPA), and sedentary behavior (SB) were verified using an accelerometer. Sleep time was obtained through interviews with parents. Components of physical fitness (cardiorespiratory fitness—CRF, speed‐agility, and lower‐body muscular strength) were assessed using the PREFIT Battery. To verify the association between 24‐hour movement behaviors and physical fitness, the compositional analysis was used, and for the time reallocation, the compositional isotemporal substitution analysis was used for active behaviors (LPA and MVPA). The daily composition, adjusted for body mass index, sex, and age, was significantly associated with CRF (P =.007; r2 = 0.29), speed‐agility (P <.001; r2 = 0.14), and lower‐body muscular strength (P =.01; r2 = 0.07). For CRF, the addition of MVPA, at the expense of any other behavior, was associated with significant improvements. For speed‐agility and lower‐body muscular strength, only reallocations between sleep and LPA yielded significant associations. The variation in CRF, speed‐agility, and lower‐body muscular strength was associated with the 24 hours movement composition, and reallocating 5, 10 or 15 minutes of SB or sleep for MVPA was significantly positive for CRF (P <.05). The present findings highlight the relevance of decreasing SB and increasing physical activity practice, particularly at high intensities, to promote a better CRF profile for preschoolers.

Obesity is an important risk factor associated with non‐communicable cardiometabolic diseases. Previous studies have indicated that children and adolescents with a predisposed genetic risk for obesity could benefit from an active lifestyle, but there are no studies investigating whether physical fitness moderates the association of genetics and obesity. The aim of this study was to verify the moderating role of physical fitness in the relationship between genetic risk score (GRS) and body mass index (BMI) in children and adolescents. This cross‐sectional study was carried out with 1471 children and adolescents, aged between 6 and 17 years from Santa Cruz do Sul, Brazil. Weight and height were assessed to determine BMI. Physical fitness components (cardiorespiratory fitness [CRF], lower limb strength [LLS], upper limb strength, and abdominal strength) were evaluated. The GRS was based on previously associated obesity single‐nucleotide polymorphism rs9939609 (FTO), rs6548238 (TMEM18), and rs16835198 (FNDC5). Moderation analyses were tested using linear regression models, and the interactions were represented by physical fitness components X GRS (categorical variable). All analyses were adjusted for skin color/ethnicity, sex, and sexual maturation. Significant interactions for CRF (P = 0.041), LLS (P = 0.041), and abdominal strength (P = 0.046) X 5 and 6 risk alleles with BMI were found only in adolescents. In addition, there was evidence that fitness components attenuated the high genetic predisposition to high BMI. Physical fitness components are moderators in the relationship between GRS and BMI in adolescents. These findings highlight the need for interventions targeting to improve this aspect, which is an important health indicator in all ages. [ABSTRACT FROM AUTHOR]

High muscular fitness (MF) and high adherence to the Southern European Atlantic Diet (the SEADiet) have been associated with several positive metabolic outcomes. The purpose of the present study was two-fold: (i) to explore the independent associations between MF and C-reactive protein (CRP) levels; and (ii) to investigate the combined impact of MF and SEADiet on the CRP levels in a sample of adolescents. A cross-sectional school-based study was conducted on 463 adolescents (272 girls) aged 15–18 years, from the Portuguese Azorean Archipelago. Anthropometric indicators (stature, body mass, waist circumference (WC)) were measured by standardized protocols and pubertal stages were assessed by Tanner criteria. Blood samples were taken after an overnight fast. MF was assessed by the curl-up and push-up tests (from the Fitnessgram test battery). Adherence to the SEADiet was assessed with a semi-quantitative food frequency questionnaire. Linear regression models showed that MF was inversely associated with hs-CRP (unstandardizedB = −0.127;p < .009), after adjustments for age, sex, and pubertal stage, adherence of SEADiet, total energy intake and low-energy reporter and WC. Analysis of covariance (ANCOVA) showed a significant difference between the low adherence of SEADiet with low MF group and those with a high adherence of SEADiet and high MF (p < .05) (F(5, 453) = 2.238,p = .040). Our results showed that MF is inversely associated with hs-CRP. In addition, the adolescents with Low adherence of SEADiet/Low MF group had high levels of hs-CRP compared those who with high adherence of SEADiet/high MF group. [ABSTRACT FROM AUTHOR]

Objective: To compare the lifetime risk of total hip replacement (THR) surgery for osteoarthritis (OA) between countries, and over time.Methods: Data on primary THR procedures performed for OA in 2003 and 2013 were extracted from national arthroplasty registries in Australia, Denmark, Finland, Norway, and Sweden. Life tables and population data were also obtained for each country. Lifetime risk of THR was calculated for 2003 and 2013 using registry, life table, and population data.Results: In 2003, lifetime risk of THR ranged from 8.7% (Denmark) to 15.9% (Norway) for females, and from 6.3% (Denmark) to 8.6% (Finland) for males. With the exception of females in Norway (where lifetime risk started and remained high), lifetime risk of THR increased significantly for both sexes in all countries from 2003 to 2013. In 2013, lifetime risk of THR was as high as 1 in 7 women in Norway, and 1 in 10 men in Finland. Females consistently demonstrated the highest lifetime risk of THR at both time points. Notably, lifetime risk for females in Norway was approximately double the risk for males in 2003 (females 15.9% [95% confidence interval (95% CI) 15.6-16.1], males 6.9% [95% CI 6.7-7.1]), and 2013 (females 16.0% [95% CI 15.8-16.3], males 8.3% [95% CI 8.1-8.5]).Conclusion: Using representative, population-based data, this study found statistically significant increases in the lifetime risk of THR in 5 countries over a 10-year period, and substantial between-sex differences. These multinational risk estimates can inform resource planning for OA service delivery. [ABSTRACT FROM AUTHOR]

Objective: To compare healthcare utilisation outcomes among older hospitalised patients with and without cognitive impairment, and to compare the costs associated with these outcomes.Methods: Retrospective cohort study of administrative data from a large teaching hospital in Melbourne, Australia from 1 July 2006 to 30 June 2012. People with cognitive impairment were defined as having dementia or delirium coded during the admission. Outcome measures included length of stay, unplanned readmissions within 28 days and costs associated with these outcomes. Regression analysis was used to compare differences between those with and without cognitive impairment.Results: There were 93 300 hospital admissions included in the analysis. 6459 (6.9%) involved cognitively impaired patients. The adjusted median length of stay was significantly higher for the cognitively impaired group compared with the non-cognitively impaired group (7.4 days 6.7-10.0 vs 6.6 days, interquartile range 5.7-8.3; p < 0.001). There were no differences in odds of 28-day readmission. When only those discharged back to their usual residence were included in the analysis, the risk of 28-day readmission was significantly higher for those with cognitive impairment compared with those without. The cost of admissions involving patients with cognitive impairment was 51% higher than the cost of those without cognitive impairment.Conclusions: Hospitalised people with cognitive impairment experience significantly greater length of stay and when discharged to their usual residence are more likely to be readmitted to hospital within 28 days compared with those without cognitive impairment. The costs associated with hospital episodes and 28-day readmissions are significantly higher for those with cognitive impairment. Copyright © 2016 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Objective: To explore the usefulness and accessibility of different delivery modes of disease-related education and support, as perceived by younger people with osteoarthritis (OA).Methods: People ages 20-55 years with hip or knee OA were recruited from 3 major Australian public hospitals and the community (n = 147). Data were collected on use of disease-related education and support services, as well as perceived usefulness and accessibility of delivery modes including group-based programs, online resources, telephone helplines, mailed information, social media, and mobile applications (rated on visual analog scales from 1-10; higher scores indicate greater usefulness or accessibility).Results: Very few participants had used social media (5%), group self-management programs (3%), or telephone helplines (2%) to obtain OA information. Mailed information packs and online education programs were considered the most useful (median usefulness scores 8.0 and 7.0, respectively) and accessible methods (median accessibility scores 10.0 and 9.0, respectively) for providing OA education and support. Social media was perceived as least useful (median usefulness score 2.0) and least accessible; 45% of participants considered it "not at all useful," while 35% reported it would be "very difficult" to access OA education and support by this means. Less educational attainment was associated with greater perceived difficulty in accessing online/electronic delivery modes, while people in paid work perceived easier access.Conclusion: These data highlight the value of mailed information and online education to younger people with OA and can be used to develop targeted resources for individuals of working age. Social media was not a highly valued source of disease-related education and support. [ABSTRACT FROM AUTHOR]

Objective: To investigate whether simultaneous telephone coaching improves the clinical effectiveness of a physiotherapist-prescribed home-based physical activity program for knee osteoarthritis (OA).Methods: A total of 168 inactive adults ages ≥50 years with knee pain on a numeric rating scale ≥4 (NRS; range 0-10) and knee OA were recruited from the community and randomly assigned to a physiotherapy (PT) and coaching group (n = 84) or PT-only (n = 84) group. All participants received five 30-minute consultations with a physiotherapist over 6 months for education, home exercise, and physical activity advice. PT+coaching participants also received 6-12 telephone coaching sessions by clinicians trained in behavioral-change support for exercise and physical activity. Primary outcomes were pain (NRS) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC; score range 0-68]) at 6 months. Secondary outcomes were these same measures at 12 and 18 months, as well as physical activity, exercise adherence, other pain and function measures, and quality of life. Analyses were intent-to-treat with multiple imputation for missing data.Results: A total of 142 (85%), 136 (81%), and 128 (76%) participants completed 6-, 12-, and 18-month measurements, respectively. The change in NRS pain (mean difference 0.4 unit [95% confidence interval (95% CI) -0.4, 1.3]) and in WOMAC function (1.8 [95% CI -1.9, 5.5]) did not differ between groups at 6 months, with both groups showing clinically relevant improvements. Some secondary outcomes related to physical activity and exercise behavior favored PT+coaching at 6 months but generally not at 12 or 18 months. There were no between-group differences in most other outcomes.Conclusion: The addition of simultaneous telephone coaching did not augment the pain and function benefits of a physiotherapist-prescribed home-based physical activity program.

Objectives The purpose of this study was to identify the structural quality of care domains and to establish a set of structural quality indicators ( SQIs) for the assessment of care of older people with cognitive impairment in emergency departments ( EDs). Methods A structured approach to SQI development was undertaken including: 1) a comprehensive search of peer-reviewed and gray literature focusing on identification of evidence-based interventions targeting structure of care of older patients with cognitive impairment and existing SQIs; 2) a consultative process engaging experts in the care of older people and epidemiologic methods (i.e., advisory panel) leading to development of a draft set of SQIs; 3) field testing of drafted SQIs in eight EDs, leading to refinement of the SQI set; and 4) an independent voting process among the panelists for SQI inclusion in a final set, using preestablished inclusion and exclusion criteria. Results At the conclusion of the process, five SQIs targeting the management of older ED patients with cognitive impairment were developed: 1) the ED has a policy outlining the management of older people with cognitive impairment during the ED episode of care; 2) the ED has a policy outlining issues relevant to carers of older people with cognitive impairment, encompassing the need to include the (family) carer in the ED episode of care; 3) the ED has a policy outlining the assessment and management of behavioral symptoms, with specific reference to older people with cognitive impairment; 4) the ED has a policy outlining delirium prevention strategies, including the assessment of patients' delirium risk factors; and 5) the ED has a policy outlining pain assessment and management for older people with cognitive impairment. Conclusions This article presents a set of SQIs for the evaluation of performance in caring for older people with cognitive impairment in EDs. [ABSTRACT FROM AUTHOR]

Objective To describe management of osteoarthritis (OA) of the hip (OA-hip) and knee (OA-knee) by Australian general practitioners (GPs). Methods We analyzed data from the Bettering the Evaluation and Care of Health program, from April 1, 2005 to March 31, 2010. Patient and GP characteristics and encounter management data were extracted. Data were classified by the International Classification of Primary Care, version 2, and summarized using descriptive statistics and 95% confidence intervals around point estimates. Results There were 489,900 GP encounters at which OA was managed (rate of 26.4 per 1,000 encounters). OA-hip was managed at a rate of 2.3 per 1,000 encounters (n = 1,106, 8.6% OA) and OA-knee at a rate of 6.2 per 1,000 (n = 3,058, 23.7% OA). The encounter management rate per 1,000 for OA-hip was higher among non-metropolitan dwellers (2.85 per 1,000 versus 1.97 per 1,000) and lower for non-English-speaking people (1.53 per 1,000 encounters versus 2.39 per 1,000). The rate for OA-knee was higher for non-English-speaking background (8.50 per 1,000 encounters versus 6.24 per 1,000) and lower among indigenous people (3.16 per 1,000 encounters versus 6.46 per 1,000). Referral to an orthopedic surgeon was the most frequently used nonpharmacologic management (OA-knee 17.4 per 100 contacts and OA-hip 17.7 per 100), followed by advice, education, and counselling. As first-line treatment, medication prescription rates (OA-knee 78.7 per 100 contacts and OA-hip 73.2 per 100) were substantially higher than rates of lifestyle management (OA-knee 20.7 per 100 contacts and OA-hip 14.8 per 100). Conclusion OA-hip and OA-knee encounters and management differ. Nonpharmacologic treatments as first-line management were low compared with pharmacologic management rates, and surgical referral rates were high. However, lack of longitudinal data limits definitive assessment of appropriateness of care. [ABSTRACT FROM AUTHOR]

Objective To estimate the lifetime risk of total knee replacement (TKR) and examine temporal trends in TKR incidence in the state of Victoria, Australia. Methods We performed a retrospective analysis of a population-based longitudinal cohort of patients (ages ≥40 years) who received a primary TKR in Victoria from 1999-2008. Hospital separations and life tables were used to estimate lifetime risk. Temporal changes in TKR incidence were examined according to health care setting (public versus private), socioeconomic status (SES), and geographic location (regional versus metropolitan). Results There were 43,570 incidents of primary TKRs identified over the study period. In 2008, the lifetime risk of surgery was 10.4% (95% confidence interval [95% CI] 10.13-10.64%) for men and 11.9% (95% CI 11.63-12.13%) for women. TKRs increased steadily over the study period in private hospitals (overall increase of 90%) with a smaller growth in procedure numbers for public hospitals (overall increase of 40%). From 2002-2003 onward, the low SES tertile showed a lower incidence of TKR compared to the middle and high SES groups, with incidence rates of 1.09 (95% CI 1.04-1.15), 1.22 (95% CI 1.17-1.28), and 1.20 (95% CI 1.16-1.25) per 1,000 population, respectively (based on 2007-2008 figures). Increased numbers of TKRs were also found to be occurring among people residing in regional areas of Victoria (from 1.12 [95% CI 1.04-1.31] to 1.84 [95% CI 1.72-2.02] per 1,000 population). Conclusion Increases in lifetime risk of TKR were evident. Although improved access to TKR for those living in regional areas was observed, sustained disparities relating to health care setting and SES warrant further investigation. [ABSTRACT FROM AUTHOR]

Objective To comprehensively evaluate the performance of the Assessment of Quality of Life (AQoL) instrument for measuring health-related quality of life (HRQOL) in people with hip and knee joint disease (arthritis or osteoarthritis). Methods Data from 237 individuals were available for analysis from a national cross-sectional, population-based study of hip and knee joint disease in Australia. AQoL-4D data were evaluated using Rasch analysis. A range of measurement properties was explored, including model and item fit, threshold ordering, differential item functioning, and targeting. Results Good overall fit of the AQoL with the Rasch model was demonstrated across a range of tests, supporting internal validity. Only 1 item (relating to hearing) showed evidence of misfit. Most AQoL items showed logical sequencing of response option categories, with threshold disordering evident for only 2 of the 12 items (items 4 and 9). Minor issues with potential clinical and research implications include limited options for reporting pain and some evidence of measurement bias between demographic subgroups (including age and sex). Participants' HRQOL was generally better than that represented by the AQoL items (mean ± SD for person abilities −2.15 ± 1.39, mean ± SD for item difficulties 0.00 ± 0.67), indicating ceiling effects that could impact the instrument's ability to detect HRQOL improvement in population-based studies. Conclusion The AQoL is a competent tool for assessing HRQOL in people with hip and knee joint disease, although researchers and clinicians should consider the caveats identified when selecting appropriate HRQOL measures for future outcome assessment involving this patient group.

According to the authors, the rate of arthroscopy in such health condition in hospitals in Victorias has lessened through time.

ACADEMIC EMERGENCY MEDICINE 2012; 19: 439-447 © 2012 by the Society for Academic Emergency Medicine Abstract Objectives: The objective was to identify predictive factors and outcomes associated with patients who leave emergency departments (EDs) without being seen in Victoria, Australia. Methods: This was a retrospective observational study of Victorian ED patient visits between July 1, 2000, and June 30, 2005, using linked hospital, ED, and death registration data. Index ED visits were identified for patients who left without being seen (LWBS) and for those who completed ED treatment and were discharged home. Statistical analyses included a general description and univariate analysis of patient, ED visit, temporal, and hospital-level factors. Logistic regression models were developed to assess risk factors associated with LWBS status compared to patients who completed treatment, to assess 48 hour re-presentations to ED; 48-hour hospital admissions; and 2-,7-, and 30-day mortality among those who LWBS compared to those who completed treatment. Adjusted odds ratios (ORs) and 99% confidence intervals (CIs) are presented. Results: There were 239,305 LWBS episodes, for 205,500 patients over the 5-year period. Independent factors associated with LWBS patients in comparison to those who completed treatment include patients who are younger (15 to 24 years, OR = 2.46, 99% CI = 2.37 to 2.56), male (OR = 1.07, 99% CI = 1.05 to 1.08), of Australian indigenous background (OR = 1.63, 99% CI = 1.53 to 1.73), of non-English-speaking background (OR = 1.08, 99% CI = 1.06 to 1.10), noncompensable status (OR = 1.73, 99% CI = 1.68 to 1.79), self-referring (OR = 1.46, 99% CI = 1.43 to 1.49), nonassisted arrival mode (OR = 1.35, 99% CI = 1.30 to 1.40), and those with a hospital admission in the 12 months before the ED presentation (OR = 1.53, 99% CI = 1.51 to 1.55). Patients who LWBS had triage categories of lower urgency (nonurgent, OR = 8.21, 99% CI = 8.00 to 8.43), attended during the evening (OR = 1.10, 99% CI = 1.08 to 1.12), on either Sunday (OR = 1.20, 99% CI = 1.18 to 1.23) or Monday (OR = 1.20, 99% CI = 1.17 to 1.23), in winter (OR = 1.14, 99% CI = 1.12 to 1.16), with higher rates occurring in higher volume EDs (OR = 2.20, 99% CI = 2.15 to 2.26). There was no greater risk of mortality for LWBS patients compared to patients who completed treatment. The risk of hospital admission within 48 hours of discharge was lower for LWBS patients (OR = 0.60, 99% CI = 0.58 to 0.62); however, ED re-presentation risk was higher (OR = 1.63, 99% CI = 1.60 to 1.67). Conclusions: Patients who leave EDs in Victoria, Australia, without being seen are at lower risk of hospital admission and at no greater risk of mortality, but are at higher risk of re-presenting to an ED compared to patients who complete treatment and are discharged home.

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. [ABSTRACT FROM AUTHOR]

Australian Health Ministers have endorsed the hospital standardised mortality ratio (HSMR) as a key indicator of quality and safety, and efforts are currently underway towards its national implementation. In the United Kingdom, Canada, the Netherlands and the United States, the HSMR has been used for several years within organisations to monitor performance and response to various quality and safety programs. In the UK and Canada, the HSMR is also publicly reported and used to compare performance between hospitals. The validity and reliability of the HSMR as a screening tool for distinguishing low-quality from high-quality hospitals remain in doubt, and it has not yet been proven that HSMR reporting necessarily leads to worthwhile improvement in quality of care and patient outcomes. Institutions may respond to an unfavourable HSMR by "gaming" administrative data and risk-adjustment models or implementing inappropriate changes to care. Despite its apparent low cost and ease of measurement, the HSMR is currently not "fit for purpose" as a screening tool for detecting low-quality hospitals and should not be used in making interhospital comparisons. It may be better suited to monitoring changes in outcomes over time within individual institutions. [ABSTRACT FROM AUTHOR]

There is strong rationale for improving care for people with chronic conditions, including osteoarthritis (OA). Successful implementation of healthcare reform requires new concepts and directions that are strongly supported by policy, new models of care (service redesign) and changes in day-to-day practice (healthcare provider and patient practice). In this paper we discuss the extent to which policy about management of OA of the hip and knee has been translated into new service models in Australia. A structured search of government and other key health websites in Australia was performed to identify policy, funding initiatives and new services models for managing OA of the hip and knee. This search was supported by a literature review. Musculoskeletal conditions were designated a National Health Priority in Australia in 2002. Under the Better Arthritis and Osteoporosis Care initiative, Australia has developed a national policy for OA care and national evidence-based clinical practice guidelines for management of OA of the hip and knee. Only two well-described examples of new chronic disease management service models, the Osteoarthritis Clinical Pathway (OACP) model and the Osteoarthritis Hip and Knee Service (OAHKS) were identified. Primarily focused within acute care public hospital settings, these have been shown to be feasible and acceptable but have limited data on clinical impact and cost-effectiveness. While policy is extant, implementation has not been systematic and comprehensive. Clinicians have evidence-based recommendations for OA management but are poorly supported by service models to deliver these effectively and efficiently. [ABSTRACT FROM AUTHOR]

Background: Information describing variation in health outcomes for individuals with diabetes related foot disease, across socioeconomic strata is lacking. The aim of this study was to investigate variation in rates of hospital separations for diabetes related foot disease and the relationship with levels of social advantage and disadvantage. Methods: Using the Index of Relative Socioeconomic Disadvantage (IRSD) each local government area (LGA) across Victoria was ranked from most to least disadvantaged. Those LGAs ranked at the lowest end of the scale and therefore at greater disadvantage (Group D) were compared with those at the highest end of the scale (Group A), in terms of total and per capita hospital separations for peripheral neuropathy, peripheral vascular disease, foot ulceration, cellulitis and osteomyelitis and amputation. Hospital separations data were compiled from the Victorian Admitted Episodes Database. Results: Total and per capita separations were 2,268 (75.3/1,000 with diabetes) and 2,734 (62.3/1,000 with diabetes) for Group D and Group A respectively. Most notable variation was for foot ulceration (Group D, 18.1/1,000 versus Group A, 12.7/1,000, rate ratio 1.4, 95% CI 1.3, 1.6) and below knee amputation (Group D 7.4/1,000 versus Group A 4.1/1,000, rate ratio 1.8, 95% CI 1.5, 2.2). Males recorded a greater overall number of hospital separations across both socioeconomic strata with 66.2% of all separations for Group D and 81.0% of all separations for Group A recorded by males. However, when comparing mean age, males from Group D tended to be younger compared with males from Group A (mean age; 53.0 years versus 68.7 years). Conclusion: Variation appears to exist for hospital separations for diabetes related foot disease across socioeconomic strata. Specific strategies should be incorporated into health policy and planning to combat disparities between health outcomes and social status. [ABSTRACT FROM AUTHOR]

Background: Acute compartment syndrome is a serious and not uncommon complication of limb trauma. The condition is a surgical emergency, and is associated with significant morbidity if not managed appropriately. There is variation in management of acute limb compartment syndrome in Australia. Methods: Clinical practice guidelines for the management of acute limb compartment syndrome following trauma were developed in accordance with Australian National Health and Medical Research Council recommendations. The guidelines were based on critically appraised literature evidence and the consensus opinion of a multidisciplinary team involved in trauma management who met in a nominal panel process. Results: Recommendations were developed for key decision nodes in the patient care pathway, including methods of diagnosis in alert and unconscious patients, appropriate assessment of compartment pressure, timing and technique of fasciotomy, fasciotomy wound management, and prevention of compartment syndrome in patients with limb injuries. The recommendations were largely consensus based in the absence of well-designed clinical trial evidence. Conclusions: Clinical practice guidelines for the management of acute limb compartment syndrome following trauma have been developed that will support consistency in management and optimize patient health outcomes.

brand c, claydon-platt k, mccoll g & bucknall t (2010) Journal of Nursing and Healthcare of Chronic Illness 2, 75–83 Meeting the needs of people diagnosed with rheumatoid arthritis: an analysis of patient-reported experience Aim. The primary aim of the study was to explore perceived needs, and adequacy of the current model of care for people with rheumatoid arthritis (RA) who live in Victoria, Australia. Background. Rheumatoid arthritis is a chronic often disabling form of inflammatory arthritis that affects approximately 1% of the population. The condition preferentially affects women with onset most common between the ages of 39–50 years, but an important subgroup has onset in later years. Management of RA involves treatment from a range of healthcare providers over many years as well as self-management by the person affected. Yet, there is limited information available about the needs of people with RA to guide service development for this chronic condition at different stages of life. Method. In a qualitative exploratory study, a trained facilitator used semi-structured questions in taped interviews to explore; the impact of RA diagnosis, experience with healthcare providers and services, barriers to better care, and ways in which services could be improved. The research was conducted between May 2005–January 2006. Conclusions. There were 45 participants (9 male, 36 female) with a mean age at disease onset of 44 years (SD 15·4). The main themes in relation with perceived needs were emotional response, empowerment and support. Whilst participant responses could be separated and grouped within these themes, there is interdependence in the way in which service delivery currently influences perceived needs and could be improved. Relevance to clinical practice. Rheumatoid arthritis is a chronic condition in which many of the issues faced are similar to those faced by people with other chronic conditions. However, this condition also presents different issues due to its impact on younger women and the necessary focus on specialist management. These factors need to be carefully considered in designing new models of care for RA. [ABSTRACT FROM AUTHOR]

Background Known inflammatory markers have limited sensitivity and specificity to differentiate viral respiratory tract infections from other causes of acute exacerbation of COPD (AECOPD). To overcome this, we developed a multi-factorial prediction model combining viral symptoms with inflammatory markers. Methods Interleukin-6 (IL-6), serum amyloid A (SAA) and viral symptoms were measured in stable COPD and at AECOPD onset and compared with the viral detection rates on multiplex PCR. The predictive accuracy of each measure was assessed using logistic regression and receiver operating characteristics curve (ROC) analysis. Results There was a total of 33 viruses detected at the onset of 148 AECOPD, the majority 26 (79%) were picornavirus. Viral symptoms with the highest predictive values were rhinorrhoea [Odds ratio (OR) 4·52; 95% CI 1·99–10·29; P < 0·001] and sore throat (OR 2·64; 95% CI 1·14–6·08; P = 0·022), combined the AUC ROC curve was 0·67. At AECOPD onset patients experienced a 1·6-fold increase in IL-6 ( P = 0·008) and 4·5-fold increase in SAA ( P < 0·001). The addition of IL-6 to the above model significantly improved diagnostic accuracy compared with symptoms alone (AUC ROC 0·80 ( P = 0·012). Conclusion The addition of inflammatory markers increases the specificity of a clinical case definition for viral infection, particularly picornavirus infection. [ABSTRACT FROM AUTHOR]

The article discusses the role of self-management in developing medical care for patients with osteoarthritis of the hip and knee in Australia. It is said that the use of evidence-based interventions for osteoarthritis leads to enhanced quality of well-being, reduced depressed mood and improved survival. There are two well-defined self-management programs in the country namely, the Arthritis Self-Management Program and the Flinders Model. The barriers to osteoarthritis management models are cited, including workforce constraints and funding initiatives.

The article offers an overview of self-management support programs for chronically ill people in Australia. The distinction between patient self-management and self-management support is explained. Self-management support in the country is said to have been focused on chronic disease self-management education programs through the National Chronic Disease Strategy. It tackles the importance of health literary among patients, which pertains to the capacity of a person to seek, understand and utilise health information to participate in health decisions.

Health care workers agree that it is necessary to improve the quality of health care for Australian patients by designing systems to avoid the risk of preventable harm. An important component of such a system is the capacity to measure, monitor and act on health care performance data. This is the current focus of health care reform around the world, including Australia. Health care quality can be measured by a variety of methods. In response to slower than anticipated health care reform, there is increasing interest in the use of nationally defined standards, which could be subject to mandatory external reporting and remedial processes. Here, we consider the issues that are likely to arise if national standards are to be developed and implemented in Australia, and provide a model for developing the standards. [ABSTRACT FROM AUTHOR]

Delirium is a common and serious condition which is often overlooked or misdiagnosed in older people. In 2006, the first set of national clinical practice guidelines for the management of delirium in older people were developed. This paper provides an abbreviated version of the guideline document which includes recommendations for the detection of delirium (diagnosis and screening), assessment and prediction of risk factors for delirium, prevention of delirium and interventions to manage people with delirium. The guidelines reflect the available evidence base and highlight the limited high level research in delirium care, particularly in the areas of symptom management and screening for delirium.

Patients who leave the ED without being seen (LWBS) are unlikely to be satisfied with the quality of the service provided and might be at risk from conditions that have not been assessed or treated. We therefore examined the available research literature to inform the following questions: (i) In patients who attend for ED care, what factors are associated with the decision to LWBS? (ii) In patients who attend for ED care, are there adverse health outcomes associated with the decision to LWBS? (iii) Which interventions have been used to try to reduce the number of patients who attend for ED care and LWBS? From the available literature, there was insufficient evidence to draw firm conclusions; however, the literature does suggest that patients who LWBS have conditions of lower urgency and lower acuity, are more likely to be male and younger, and are likely to identify prolonged waiting times as a central concern. LWBS patients generally have very low rates of subsequent admission, and reports of serious adverse events are rare. Many LWBS patients go on to seek alternative medical attention, and they might have higher rates of ongoing symptoms at follow-up. Further research is recommended to include comprehensive cohort or well-designed case–control studies. These studies should assess a wide range of related factors, including patient, hospital and other relevant factors. They should compare outcomes for groups of LWBS patients with those who wait and should include cross-sectoral data mapping to truly detect re-attendance and admission rates. [ABSTRACT FROM AUTHOR]

Aim: Vitamin D is essential for musculoskeletal health. In addition to known high risk for older, housebound or institutionalized people, there are increasing reports of vitamin D deficiency in younger Australian populations, who are dark-skinned and/or veiled. The aim of this study is to investigate socio-cultural barriers and enablers to reducing risk of vitamin D deficiency among dark-skinned and veiled community groups in a Melbourne metropolitan area. Methods: A qualitative exploratory study was undertaken by an acute and community care partnership group based in the City of Melbourne and City of Moonee Valley areas, Victoria, Australia. Community-dwelling people 18 years or more who were dark-skinned or veiled participated. A trained facilitator used semistructured questions to explore awareness of vitamin D deficiency, knowledge about risks and barriers to risk management. Discussion was summarized and dominant themes extracted. Results: There were gender differences in awareness of risk. Men were unaware or considered themselves not to be at risk of vitamin D deficiency. Cultural issues influenced access to, and sourcing of, health information. In particular, community opinion leaders and use of local media such as radio were considered important avenues for knowledge transfer in addition to health care providers. Relocation from community settings in Africa to the built environment of Melbourne was reported to inhibit safe, comfortable and culturally appropriate access to sun exposure. Access to, and sustained use of vitamin D supplementation was limited by financial constraints. Conclusion: A comprehensive health promotion response that includes health provider and community partnerships is required to meet the complex needs of these communities. [ABSTRACT FROM AUTHOR]

Background: Acute compartment syndrome is a serious and not uncommon complication of limb trauma. The condition is a surgical emergency and is associated with significant morbidity if not diagnosed promptly and treated effectively. Despite the urgency of effective management to minimize the risk of adverse outcomes, there is currently little consensus in the published reports as to what constitutes best practice in the management of acute limb compartment syndrome. Methods: A structured survey was sent to all currently practising orthopaedic surgeons and accredited orthopaedic registrars in Australia to assess their current practice in the management of acute, traumatic compartment syndrome of the leg. Questions were related to key decision nodes in the management process, as identified in a literature review. These included identification of patients at high risk, diagnosis of the condition in alert and unconscious patients, optimal timeframe and technique for carrying out a fasciotomy and management of fasciotomy wounds. Results: A total of 264 valid responses were received, a response rate of 29% of all eligible respondents. The results indicated considerable variation in management of acute compartment syndrome of the leg, in particular in the utilization of compartment pressure measurement and the appropriate pressure threshold for fasciotomy. Of the 78% of respondents who regularly measured compartment pressure, 33% used an absolute pressure threshold, 28% used a differential pressure threshold and 39% took both into consideration. Conclusions: There is variation in the management of acute, traumatic compartment syndrome of the leg in Australia. The development of evidence-based clinical practice guidelines may be beneficial.

Objective: Functional decline is experienced by up to 50% of older hospitalised patients and is associated with increased institutionalisation, mortality and length of stay (LOS). We aimed to determine the effectiveness of an exercise program in reducing functional decline and health service utilisation in older inpatients. Methods: A single-blinded randomised controlled trial was conducted in a tertiary metropolitan hospital involving 180 acute general medical patients aged ≥ 65 years. In addition to usual physiotherapy care, the intervention group performed an exercise program for 30 minutes, twice daily, with supervision and assistance. Change in physical function was measured by the modified Barthel index (mBI). Analysis was done on an intention-to-treat basis. Results: When admission mBI scores were low, there was a greater improvement in mBI scores in the intervention group compared with the control group. The intervention group had a shorter total LOS (Hazard ratio (HR) 1.46 (95%CI 1.04–2.05); P =  0.026). [ABSTRACT FROM AUTHOR]

Objective: To determine the contributing factors that lead to increased length of stay (LOS) of patients with dementia. Methods: A case-controlled study in a tertiary metropolitan hospital general medical unit was conducted. Patients were aged 65 and over, 26 cases with dementia were identified and 26 controls without dementia were randomly selected. Results: The mean ( ± SD) LOS for patients with dementia was significantly longer than for those without dementia (20.59 ± 15.38 days vs. 9.6 ± 6.45 days, P = 0.02). In addition to dementia, severity of illness, referral to the aged care assessment team, and day of week admitted were also significant independent predictors of increased LOS. Conclusion: Reasons for increased LOS of patients with dementia remain unclear. Cognitive impairment due to dementia is likely to increase within the context of an increasing and ageing population. Specific strategies may be required within in-hospital clinical pathways to assist the needs of this group. [ABSTRACT FROM AUTHOR]

Older people are at greater risk of falls and fall-related adverse outcomes. Risk for falls is multifactorial, and relative importance of risk factors (RF) may vary according to the population studied. Although several population studies identify musculoskeletal factors as one of many RFs, there have been few studies of falls in populations with rheumatic disease. In this study we aim to assess the incidence of falls, prevalence of falls RFs and outcomes of falls in an ambulatory population with rheumatic disease. Using a retrospective cohort study design, consecutive patients attending rheumatology outpatient clinics completed a self-administered falls questionnaire that investigated falls within the previous 12 months, risk for falling and fear of falling. One hundred and fifty-five patients, with a mean age of 59.7 years (SD 15.0) completed the survey. Seventy-six patients (49%) reported one or more falls in the previous 12 months. Fifty-eight (76.3%) reported an adverse outcome which included fracture in 12 (15.8%) and hospital attendance or admission in 20 (26.7%). Fear of falling was also common, being reported in 81 (52.3%) patients. Moderately or severe fear of falling was reported in 26 (16.8%) among the whole group and in 10% of the 78 patients who had not yet experienced a fall. The findings of this study highlight the high incidence of falls and fear of falling in patients with rheumatic disease and identify groups likely to be at higher risk. These patients should be considered for falls prevention programs that have been shown to reduce falls risk and improve self-efficacy. [ABSTRACT FROM AUTHOR]

Objective: To quantify the additional hospital length of stay (LOS) and costs associated with in-hospital falls and fall injuries in acute hospitals in Australia.Design, Setting and Participants: A multisite prospective cohort study conducted during 2011-2013 in the control wards of a falls prevention trial (6-PACK). The trial included all admissions to 12 acute medical and surgical wards of six Australian hospitals. In-hospital falls data were collected from medical record reviews, daily verbal reports by ward nurse unit managers, and hospital incident reporting and administrative databases. Clinical costing data were linked for three of the six participating hospitals to calculate patient-level costs.Outcome Measures: Hospital LOS and costs associated with in-hospital falls and fall injuries for each patient admission.Results: We found that 966 of a total of 27 026 hospital admissions (3.6%) involved at least one fall, and 313 (1.2%) at least one fall injury, a total of 1330 falls and 418 fall injuries. After adjustment for age, sex, cognitive impairment, admission type, comorbidity and clustering by hospital, patients who had an in-hospital fall had a mean increase in LOS of 8 days (95% CI, 5.8-10.4; P < 0.001) compared with non-fallers, and incurred mean additional hospital costs of $6669 (95% CI, $3888-$9450; P < 0.001). Patients with a fall-related injury had a mean increase in LOS of 4 days (95% CI, 1.8-6.6; P = 0.001) compared with those who fell without injury, and there was also a tendency to additional hospital costs (mean, $4727; 95% CI, -$568 to $10 022; P = 0.080).Conclusion: Patients who experience an in-hospital fall have significantly longer hospital stays and higher costs. Programs need to target the prevention of all falls, not just the reduction of fall-related injuries. [ABSTRACT FROM AUTHOR]
