The Program to Enhance Adjustment to Residential Living (PEARL) is a five session intervention primarily designed to address high rates of depression in newly admitted residents. This study reports the efficacy of PEARL on secondary outcomes of resident adjustment, symptoms of anxiety, quality of life, and stress.A cluster randomized controlled trial was conducted with 219 newly admitted nursing home residents (M age = 85.5 years) from 42 nursing homes. Outcomes were assessed at baseline, post-intervention, and at two and six month post-intervention follow-up, compared to a standard care condition.There was a significant overall condition by time interaction for adjustment (This study demonstrates the broad effects of PEARL on the wellbeing of newly admitted residents.PEARL is a brief intervention that may be feasible for routine use in nursing homes to facilitate adjustment and improve residents' quality of life.

This study evaluated a training program to support the delivery of consumer directed care (CDC). It was hypothesized that both interventions, compared to the control condition, would demonstrate increased levels of CDC in nursing homes, increased staff practice of CDC, and improved resident QoL. The training plus support group was expected to show greater gains, compared to the training only group.In a cluster RCT design, 33 nursing homes were randomly allocated to one of three conditions: training plus support, training only, and care as usual. Outcome measures included level of CDC within each home, staff practice of CDC, and resident QoL.Hypotheses for this study were partially supported. Nursing homes became more CDC-oriented but with minimal changes in staff practice of CDC. Resident QoL also demonstrated limited change. The findings are discussed in terms of organizational barriers to change within nursing homes.

BACKGROUND Lumbar spinal fusion (LSF) outcomes for workers' compensation patients are worse than for the general population. The objectives were to examine the long-term work capacity, opioid prescription and mental health outcomes of injured workers who have undergone LSF surgery in Victoria, Australia, and to identify demographic and pre- and post-operative characteristics associated with these outcomes. METHODS Retrospective study of 874 injured workers receiving elective LSF from 2008 to 2016 in the Victorian workers' compensation system. WorkSafe Victoria's claims data were used to infer outcomes for recovery. Association of demographics, pre-surgery and surgery variables with outcomes were modelled using multivariate multinomial logistic regression analyses. RESULTS Twenty-four months after LSF surgery, 282 (32.3%) of the 874 injured workers had substantial work capacity, 388 (44.4%) were prescribed opioids, and 330 (37.8%) were receiving mental health treatment. Opioid prescription and limited work capacity before surgery were independent strong predictors of opioid prescription, reduced work capacity and mental health treatment 24 months after LSF. Pre-operative mental health treatment was associated with the use of mental health treatment at 24 months. Other predictors for poor outcomes included a greater than 12-month duration from injury to surgery, LSF re-operation and common law or impairment benefit lodgement before surgery. CONCLUSION An association between pre-operative factors and post-operative outcomes after LSF in a Victorian workers' compensation population was identified, suggesting that pre-operative status may influence outcomes and should be considered in LSF decisions. The high opioid use indicates that opioid management before and after surgery needs urgent review.

Importance: Nonspecific effects, particularly placebo effects, are thought to contribute significantly to the observed effect in surgical trials. Objective: To estimate the proportion of the observed effect of surgical treatment that is due to nonspecific effects (including the placebo effect). Data Sources: Published Cochrane reviews and updated, extended search of MEDLINE, Embase, and CENTRAL until March 2019. Study Selection: Published randomized placebo-controlled surgical trials and trials comparing the effect of the same surgical interventions with nonoperative controls (ie, no treatment, usual care, or exercise program). Data Extraction and Synthesis: Pairs of authors independently screened the search results, assessed full texts to identify eligible studies and the risk of bias of included studies, and extracted data. The proportion of all nonspecific effects was calculated as the change in the placebo control divided by the change in the active surgery and pooled in a random-effect meta-analysis. To estimate the magnitude of the placebo effect, we pooled the difference in outcome between placebo and nonoperative controls and used metaregression to estimate the association between the type of control group and the treatment effect (difference between the groups), adjusting for risk of bias, sample size, and type of outcome. Main Outcomes and Measures: Between- and within-group effect sizes expressed as Hedges g. Results: In this review, 100 trials were included comprising data from 62 trials with placebo controls (3 also included nonoperative controls), and 38 trials with nonoperative controls (32 interventions; 10 699 participants). Risk of bias across trials was comparable except for performance and detection bias, which was high in trials with nonoperative controls. The mean nonspecific effects accounted for 67% (95% CI, 61% to 73%) of the observed change after surgery; however, this varied widely between different procedures. The estimated surgical placebo effect had a standardized mean difference (SMD) of 0.13 (95% CI, −0.26 to 0.51). Trials with placebo and nonoperative controls found comparable treatment effects (SMD, −0.09 [95% CI, −0.35 to 0.18]; 15 interventions; 73 between-group effects; adjusted analysis: SMD, −0.11 [95% CI, −0.37 to 0.15]). Conclusions and Relevance: In this review, the change in health state after surgery was composed largely of nonspecific effects, but no evidence supported a large placebo effect. Placebo-controlled surgical trials may be redundant when trials with nonoperative controls consistently report no substantial association from surgery compared with nonoperative treatment.

BackgroundElectronic health record datasets have been used to determine the prevalence of musculoskeletal complaints in general practice but not to examine the associated characteristics and healthcare utilisation at the primary care level.AimTo describe the prevalence and characteristics of patients presenting to general practice with musculoskeletal complaints.Design and SettingA five-year analysis within three Primary Health Networks (PHNs) in Victoria, Australia. MethodWe included patients with at least one face-to-face consultation 2014 to 2018 inclusive and a low back (≥18 years), and/or neck, shoulder or knee (≥45 years) complaint determined by SNOMED codes derived from diagnostic text within the medical record. We determined prevalence, socio-demographic characteristics and diagnostic codes for patients with an eligible diagnosis; and number of consultations within one year of diagnosis.Results324,793/1,294,021 (25%) presented with at least one musculoskeletal diagnosis, of whom 41% (n=133,279) fulfilled our inclusion criteria. There were slightly more females (n=73,428, 55%), two-thirds (n=88,043) were of working age (18-65 years) and 83,816 (63%) had at least one comorbidity. Over half had a low back diagnosis (n=76,504, 57%) followed by knee (n=33,438, 25%), shoulder (n=26,335, 20%) and neck (n=14,492, 11%). Most codes included ‘pain’ and/or ‘ache’ (low back: 58%, neck: 41%, shoulder: 32%, knee 26%). Median (IQR) all-cause consultations per patient within one year of diagnosis was 7 (4-12). ConclusionThe burden of MSK complaints at the primary care level is high as evidenced by the prevalence of people with musculoskeletal complaints presenting to a general practitioner, the preponderance of comorbidities and the numerous consultations per year. Identification and evaluation of strategies to reduce this burden are needed.

Background: Depression is common in nursing homes, particularly among newly admitted residents. This cluster randomised controlled trial evaluated the effectiveness of the Program to Enhance Adjustment to Residential Living (PEARL) in reducing depression in this group. Methods: Participants were 219 newly-admitted residents (mean of 4.4 weeks since admission) in 42 nursing homes in Melbourne, Australia, with a mean age of 85.5 years (SD = 7.3). Nursing homes were randomly allocated to the intervention or standard care condition. Level of depressive symptoms was evaluated at baseline (T1), one week post- intervention (T2), 2 months post-intervention (T3, primary end point), and 6 months post-intervention (T4). Changes in depressive symptoms in the intervention and control groups over time were compared using a multilevel model, with nursing homes modelled as random intercept. Results: In intention to treat analyses, depressive symptoms reduced from T1 to T3 to a greater degree in the intervention condition (Mchange=2.56, SDchange=5.71) than in the control (Mchange=0.63, SDchange=5.25), with a significant, small-medium treatment effect size (p=.035; Cohen's d=0.36). The reduction in depressive symptoms from T1 to T4 was not significant (p=.369; Cohen's d=0.32). Limitations: The findings require replication, particularly comparing PEARL with an active control condition. Conclusions: PEARL is a simple, brief program that was effective in reducing symptoms of depression in newly admitted nursing home residents.

Objective: Evaluate the Pain Impact Index, a simple, brief, easy-to-use, and novel tool to assess the impact of chronic pain in community-dwelling older adults. Methods: A Rasch modelling analysis was undertaken in Stata using a partial credit model suited to the Likert-type items that comprised the Index. The Index was evaluated for ordering of category thresholds, unidimensionality, overall fit to the Rasch model, measurement bias (Differential Item Functioning, DIF), targeting, and construct validity. Results: The four-item Pain Impact Index was self-completed by 6454 community-dwelling Australians who were aged at least 70 years and experienced pain on most days. Two items showed evidence of threshold disordering, and this was resolved by collapsing response categories (from 5 to 3) for all items. The rescored Index conformed to the unidimensionality assumption and had satisfactory fit with the Rasch model (analyses conducted on a reduced sample size to mitigate the potential for overpowering: n = 377, P > 0.0125, power > 77%). When considering uniform DIF, the most frequent sources of measurement bias were age, knee pain, and upper back pain. When considering nonuniform DIF, the most frequent source of measurement bias was knee pain. The Index had good ability to differentiate between respondents with different levels of pain impact and had highest measurement precision for respondents located around the average level of pain impact in the study sample. Both convergent and discriminant validity of the Index were supported. Conclusion: The Pain Impact Index showed evidence of unidimensionality, was able to successfully differentiate between levels of pain impact, and had good evidence of construct validity.

Aims This study aimed to describe the use of revision knee arthroplasty in Australia and examine changes in lifetime risk over a decade. Methods De-identified individual-level data on all revision knee arthroplasties performed in Australia from 2007 to 2017 were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Population data and life tables were obtained from the Australian Bureau of Statistics. The lifetime risk of revision surgery was calculated for each year using a standardized formula. Separate calculations were undertaken for males and females. Results In total, 43,188 revision knee arthroplasty procedures were performed in Australia during the study period, with a median age at surgery of 69 years (interquartile range (IQR) 62 to 76). In 2017, revision knee arthroplasty rates were highest for males aged 70 to 79 years (102.9 procedures per 100,000 population). Lifetime risk of revision knee arthroplasty for females increased slightly from 1.61% (95% confidence interval (CI) 1.53% to 1.69%) in 2007 to 2.22% (95% CI 2.13% to 2.31%) in 2017. A similar pattern was evident for males, with a lifetime risk of 1.43% (95% CI 1.36% to 1.51%) in 2007 and 2.02% (95% CI 1.93% to 2.11%) in 2017. A decline in procedures performed for loosening/lysis (from 41% in 2007 to 24% in 2017) and pain (from 14% to 9%) was evident, while infection became an increasingly common indication (from 19% in 2007 to 29% in 2017). Conclusion Well-validated national registry data can help us understand the epidemiology of revision knee arthroplasty, including changing clinical indications. Despite a small increase over a decade, the lifetime risk of revision knee arthroplasty in Australia is low at one in 45 females and one in 50 males. These methods offer a population-level approach to quantifying revision burden that can be used for ongoing national surveillance and between-country comparisons.

Major osteoporotic fractures (MOFs) are associated with a rapid decline in health-related quality of life (HRQoL); however, there is limited knowledge about which healthcare services positively affect HRQoL postfracture. This study aimed to identify specific combinations of health service use associated with recovery of HRQoL 12 months post-MOF. The analyses included 4126 adults aged ≥50 years with an MOF (1657 hip, 1354 distal forearm, 681 vertebrae, 434 humerus) participating in the International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS), a multinational observational study (Australia, Austria, Estonia, France, Italy, Lithuania, Mexico, Russia, Spain, United Kingdom, and United States). HRQoL at prefracture and 12 months postfracture was measured using the EuroQoL questionnaire (EQ-5D-3L). Health service use data were collected via participant interviews and medical record reviews including in-hospital care; outpatient care; community services; and medication use. Data analyses involved two stages: (i) latent class analyses to identify different combinations of health service use ("classes"); and (ii) logistic regression to assess effects of classes on HRQoL recovery. Analyses were repeated excluding hip fractures (non-hip MOFs). Overall, 2057 MOF participants (49.9%) recovered to their prefracture HRQoL at 12-month follow-up; this proportion was higher for non-hip MOFs (n = 1439; 58.3%). Several distinct classes were identified across countries (range, 2-5 classes). Classes that were associated with increased odds of HRQoL recovery were characterized by a combination of hospital presentations without admission; outpatient department visits; allied health visits; vitamin D/calcium supplementation; and/or non-opioid analgesic use. Similar classes were observed for non-hip MOFs. Understanding country-specific healthcare service pathways that influence greater recovery of HRQoL, particularly services that are uncommon in some countries and routine in others, could improve postfracture care on a global scale. © 2020 American Society for Bone and Mineral Research (ASBMR).

s was very high (intraclass correlation coefficient 0.996). Any disagreements were resolved through a discussion between all authors. Given the large number of potentially relevant measures identified, only those measures that were used at least 4 times in the screened abstracts were selected for this review. Consequently, this report provides reviews of 4 generic health profiles: the Medical Outcomes Study Short Form 36 and Short Form 12 Health Surveys, the Nottingham Health Profile, and the Sickness Impact Profile, and 4 health utility measures: the Medical Outcomes Study Short Form 6D, the Health Utilities Index Mark 3, Quality of Well-Being Scale (selfadministered), and the Assessment of Quality of Life Scale. Although the EuroQol 5-domain is also frequently used in rheumatology, the review of this measure is included in Measures of Disability article in this issue.

This study determined changes in multiple aspects of mental health and wellbeing in newly admitted nursing home residents, and identified risk and protective factors.Participants were 204 residents recently admitted to one of 42 nursing homes in Melbourne, Australia. A subgroup of 82 participants were followed up eight months post-admission. Depression, anxiety, stress, adjustment, and quality of life were assessed at baseline and follow-up. Predictive factors (demographics, health, transition factors, nursing home characteristics) were examined in multiple regression analyses.Rates of depression and anxiety were high at both baseline and follow-up. Low self-rated health and medical comorbidity predicted poor wellbeing at baseline. Higher perceived control in the relocation to the nursing home and engagement in meaningful activities were associated with better post-admission outcomes. Baseline psychotropic medication use predicted lower anxiety at follow-up but did not impact depressive symptoms.There were no significant changes in mental health and wellbeing from one to eight months post-admission. The negative effect of residing in a for-profit nursing home requires further investigation.Individual activity scheduling and an opportunity to participate in relocation decision-making and planning may support resident wellbeing post-admission.

IntroductionGeneral practice is integral to the Australian healthcare system. Outcome Health’s POpulation Level Analysis and Reporting (POLAR) database uses de-identified electronic health records to analyse general practice data in Australia. Previous studies using routinely collected health data for research have not consistently reported the codes and algorithms used to describe the population, exposures, interventions and outcomes in sufficient detail to allow replication. This paper reports a study protocol investigating patterns of care for people presenting with musculoskeletal conditions to general practice in Victoria, Australia. Its focus is on the systematic approach used to classify and select eligible records from the POLAR database to facilitate replication. This will be useful for other researchers using routinely collected health data for research.Methods and analysisThis is a retrospective cohort study. Patient-related data will be obtained through electronic health records from a subset of general practices across three primary health networks (PHN) in southeastern Victoria. Data for patients with a low back, neck, shoulder and/or knee condition and who received at least one general practitioner (GP) face-to-face consultation between 1 January 2014 and 31 December 2018 will be included. Data quality checks will be conducted to exclude patients with poor data recording and/or non-continuous follow-up. Relational data files with eligible and valid records will be merged to select the study cohort and the GP care received (consultations, imaging requests, prescriptions and referrals) between diagnosis and 31 December 2018. Number and characteristics of patients and GPs, and number, type and timing of imaging requests, prescriptions for pain relief and referrals to other health providers will be investigated.Ethics and disseminationEthics approval was obtained from the Cabrini and Monash University Human Research Ethics Committees (Reference Numbers 02-21-01-19 and 16975, respectively). Study findings will be reported to Outcome Health, participating PHNs, disseminated in academic journals and presented in conferences.

Background Infantile nystagmus syndrome (INS) is a type of eye movement disorder that can negatively impact vision. Currently, INS cannot be cured, but its effects can potentially be treated pharmacologically, optically, or surgically. This review focuses on the surgical interventions for INS. Despite the range of surgical interventions available, and currently applied in practice for the management of INS, there is no clear consensus, and no accepted clinical guidelines regarding the relative efficacy and safety of the various treatment options. A better understanding of these surgical options, along with their associated side effects, will assist clinicians in evidence-based decision-making in relation to the management of INS. Objectives To assess the efficacy and safety of surgical interventions for INS. Search methods We searched CENTRAL, MEDLINE Ovid, Embase Ovid, ISRCTN registry, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) to 3 July 2020, with no language restrictions. Selection criteria We included randomised controlled trials (RCTs) studying the efficacy and safety of surgical options for treating INS. Data collection and analysis Our prespecified outcome measures were the change from baseline in: binocular best-corrected distance visual acuity; head posture; amplitude, frequency, intensity, and foveation period durations of the nystagmus waveform; visual recognition times; quality of life and self-reported outcome measures; incidence of adverse effects with a probable causal link to treatment; and permanent adverse effects after surgery. Two review authors independently screened titles and abstracts and full-text articles, extracted data from eligible RCTs, and judged the risk of bias using the Cochrane tool. We reached consensus on any disagreements by discussion. We summarised the overall certainty of the evidence using the GRADE approach. Main results We only identified one eligible RCT (N = 10 participants), undertaken in India. This trial randomised participants to receive either a large retro-equatorial recession of the horizontal rectus muscle of 9 mm on the medial rectus and 12 mm on the lateral rectus, or a simple tenotomy and resuturing of the four horizontal rectus muscles. We did not identify any RCTs comparing a surgical intervention for INS relative to no treatment. In the single eligible RCT, both eyes of each participant received the same intervention. The participants' age and gender were not reported, nor was information on whether participants were idiopathic or had sensory disorders. The study only included participants with null in primary position and did not explicitly exclude those with congenital periodic alternating nystagmus. The study did not report funding source(s) or author declaration of interests. The evaluation period was six months. We judged this study at low risk for sequence generation and other sources of bias, but at high risk of bias for performance and detection bias. The risk of bias was unclear for selection bias, attrition bias, and reporting bias. There is very uncertain evidence about the effect of the interventions on visual acuity and change in amplitude, frequency, and intensity of the nystagmus waveform. We were unable to calculate relative effects due to lack of data. None of the participants in either intervention group reported adverse effects at six-month follow-up (very low-certainty evidence). There was no quantitative data reported for quality of life, although the study reported an improvement in quality of life after surgery in both intervention groups (very low-certainty evidence). Change in head posture, foveation period durations of the nystagmus waveform, visual recognition times, and permanent adverse effects after surgery were not reported in the included study. We judged the certainty of the evidence, for both the primary and secondary efficacy outcomes, to be very low. Due to a lack of comprehensive reporting of adverse events, there was also very low-certainty of the safety profile of the evaluated surgical interventions in this population. As such, we are very uncertain about the relative efficacy and safety of these interventions for the surgical management of INS. Authors' conclusions This systematic review identified minimal high-quality evidence relating to the efficacy and safety of surgical interventions for INS. The limited availability of evidence must be considered by clinicians when treating INS, particularly given these procedures are irreversible and often performed on children. More high-quality RCTs are needed to better understand the efficacy and safety profile of surgical interventions for INS. This will assist clinicians, people with INS, and their parents or caregivers to make evidence-based treatment decisions.

BACKGROUND: Well-validated data from arthroplasty registries provide an opportunity to understand contemporary use of revision hip replacement at a national level. Such information can underpin health-care resource allocation and surgical workforce planning. The purposes of the present study were to describe the demographic characteristics of patients managed with revision hip replacement surgery in Australia and to examine changes in the lifetime risk of revision hip replacement over a decade. METHODS: Deidentified individual-level data on all revision hip replacement procedures performed in Australia from 2007 to 2017 were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Life tables and population data were sourced from the Australian Bureau of Statistics. The lifetime risk of revision surgery each year was estimated with use of a standardized approach, with separate calculations for males and females. RESULTS: A total of 46,086 revision hip replacement procedures were performed from 2007 to 2017. The median age at the time of surgery was 72 years (interquartile range, 63 to 80 years). While loosening or lysis became less frequent reasons for revision over time (from 51% in 2007 to 28% in 2017), revision hip replacement for infection became increasingly common (from 14% in 2007 to 25% in 2017). Revisions for metal-related pathology peaked in 2011. Utilization rates were highest for males ≥80 years of age (127.9 procedures per 100,000 population in 2017). Although a small rise was evident in 2011 and 2012 (to 2.39% and 2.22%, respectively), the lifetime risk of revision hip replacement in females decreased from 1.90% (95% confidence interval [CI], 1.82% to 1.99%) in 2007 to 1.74% (95% CI, 1.66% to 1.82%) in 2017. A similar pattern was evident for males; the lifetime risk was 1.78% (95% CI, 1.69% to 1.86%) in 2007 and 1.57% (95% CI, 1.49% to 1.65%) in 2017. CONCLUSIONS: These data enable us to understand the epidemiology of revision hip replacement in Australia, including the shifting clinical indications for this procedure. At a population level, the lifetime risk of revision hip replacement remains low at

ObjectiveTo explore the moderating effects of sociodemographic variables on treatment benefits received from participating in an internet intervention for depression.DesignRandomised, assessor-blind, controlled trial.SettingOnline intervention, with participant recruitment using multiple settings, including inpatient and outpatient medical and psychological clinics, depression online forums, health insurance companies and the media (eg, newspaper, radio).ParticipantsThe EVIDENT trial included 1013 participants with mild to moderate depressive symptoms.InterventionsThe intervention group subjects (n=509) received an online intervention (Deprexis) in addition to care as usual (CAU), while 504 participants received CAU alone.MethodsTo explore subgroup differences, moderating effects were investigated using linear regression models based on intention-to-treat analyses. Moderating effects included sex, age, educational attainment, employment status, relationship status and lifetime frequency of episodes.Primary and secondary outcome measuresThe primary endpoint was change in self-rated depression severity measured by the Patient Health Questionnaire-9 (PHQ-9), comparing baseline versus 12-week post-test assessment. Secondary outcome measures were the Hamilton Rating Scale for Depression and the Quick Inventory of Depressive Symptoms each at 12 weeks and at 6 and 12 months, and PHQ-9 at 6 and 12 months, respectively. In this article, we focus on the primary outcome measure only.ResultsBetween-group differences were observed in post-test scores, indicating the effectiveness of Deprexis. While the effects of the intervention could be demonstrated across all subgroups, some showed larger between-group differences than others. However, after exploring the moderating effects based on linear regression models, none of the selected variables was found to be moderating treatment outcomes.ConclusionsOur findings suggest that Deprexis is equally beneficial to a wide range of people; that is, participant characteristics were not associated with treatment benefits. Therefore, participant recruitment into web-based psychotherapeutic interventions should be broad, while special attention may be paid to those currently under-represented in these interventions.Trial registration numberNCT01636752.

There is an increasing interest in peer interventions in the management of chronic conditions, but evidence on peer interventions for body weight is lacking. The aim of this study was to examine the efficacy of peer interventions on body weight, energy intake, and physical activity in adults. Interventions delivered by peer (lay member that participants identify with) were included. We searched 14 databases. Outcomes were combined in the meta-analysis using the inverse variance random-effects model. From 2435 articles, 65 articles were included in the systematic review and meta-analysis (n = 15,673). Peer interventions resulted in significant reduction in weight (mean difference [MD] -1.05 kg; 95% confidence interval [CI] -1.68, -0.43; 95% prediction interval [PI] -3.25, 1.14; 28 studies; 7142 participants), BMI (MD -0.24 kg/m2 ; 95% CI -0.44, -0.04; 95% PI -0.92, 0.45; 25 studies; 6672 participants), waist circumference (MD -0.75 cm; 95% CI -1.29, -0.21; 95% PI -1.36, -0.14; 12 studies; 4280 participants), and significant increase in physical activity (SMD 0.20; 95% CI 0.09, 0.32; 95% PI -0.46, 0.86; 41 studies; 10,778 participants) with no significant effect on energy intake. This study suggests peer interventions are effective in reducing waist circumference, but further research is needed to confirm its effect on other obesity-related outcomes.

Purpose We aimed to identify combinations of health service use specific to each major osteoporotic fracture (MOF) site – hip, distal forearm, vertebrae and humerus – associated with recovery of health-related quality of life (HRQoL) 12-months post-MOF. Methods Patients were 4126 adults aged ≥50 years with a MOF (1657 hip, 1354 distal forearm, 681 vertebral, 434 humerus) from the International Costs and Utilities Related to Osteoporotic fractures Study (Australia, Austria, Estonia, France, Italy, Lithuania, Mexico, Russia, Spain and the UK). HRQoL (pre-fracture and 12-months post-fracture) was measured using the EQ-5D-3L. Health service use data were collected via interviews and medical record reviews and included in-hospital care, outpatient care, supported living, community health services, and medication use. Latent class analyses were undertaken to identify different combinations of health service use (“classes”); and logistic regression to assess associations between classes and HRQoL recovery. Fracture site-specific analyses were performed using pooled data from all 10 countries. Results The proportion of patients who recovered to their pre-fracture HRQoL at 12-month follow-up varied across fracture sites: 37.3%, 65.8%, 48.9% and 49.5% for hip, distal forearm, vertebrae, and humerus, respectively. We observed several site-specific classes associated with improved odds of HRQoL recovery. Generally, the combination of hospital presentations without admission; primary care center visits; use of osteoporosis-related medications; vitamin D/calcium supplementation; and non-opioid analgesic use was associated with greater likelihood of HRQoL recovery. Conclusion The identified fracture site-specific health service use pathways associated with recovery of HRQoL could potentially improve the management and health outcomes of patients treated for a MOF.

BACKGROUND: Meibomian gland dysfunction (MGD) is the major cause of evaporative dry eye disease, which is the more prevalent form of dry eye disease. Intense pulsed light (IPL) therapy, involving treatment of the skin near the eyelids, has emerged as a potential treatment for MGD. OBJECTIVES: To evaluate the effectiveness and safety of intense pulsed light (IPL) for the management dry eye disease resulting from meibomian gland dysfunction (MGD). SEARCH METHODS: We searched CENTRAL, MEDLINE (Ovid), Embase Ovid and three trial registers for eligible clinical trials on 1 August 2019. There were no restrictions on publication status, date or language. SELECTION CRITERIA: We included randomised controlled trials (RCTs) studying the effectiveness or safety of IPL for treating MGD. DATA COLLECTION AND ANALYSIS: Our outcomes of interest were the change from baseline in subjective dry eye symptoms, adverse events, changes to lipid layer thickness, tear break-up time (TBUT), tear osmolarity, eyelid irregularity, eyelid telangiectasia, meibomian gland orifice plugging, meibomian gland dropout, corneal sodium fluorescein staining and conjunctival lissamine green staining. Two review authors independently screened abstracts and full-text articles, extracted data from eligible RCTs and judged the risk of bias using the Cochrane tool. We reached consensus on any disagreements by discussion. We summarised the overall certainty of the evidence using the GRADE Working Group approach. MAIN RESULTS: We included three RCTs, one from New Zealand, one from Japan and one from China, published between 2015 and 2019. Together, these trials enrolled 114 adults (228 eyes). Two studies used a paired-eye (inter-eye comparison) design to evaluate the effects of a sham (control) IPL treatment relative to an actual IPL treatment. One study randomised individuals to either an IPL intervention combined with meibomian gland expression (MGX), or MGX alone (standard therapy). The study follow-up periods ranged from 45 days to nine months. None of the trials were at low risk of bias in all seven domains. The first authors of two included studies were in receipt of funding from patents or the manufacturers of IPL devices. The funding sources and declaration of interests were not given in the report of the third included trial. All three trials evaluated the effect of IPL on dry eye symptoms, quantified using the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire. Pooling data from two trials that used a paired-eye design, the summary estimate for these studies indicated little to no reduction in dry eye symptoms with IPL relative to a sham intervention (mean difference (MD) -0.33 units, 95% confidence interval (CI) -2.56 to 1.89; I² = 0%; 2 studies, 144 eyes). The other study was not pooled as it had a unit-of-analysis error, but reported a reduction in symptoms in favour of IPL (MD -4.60, 95% CI -6.72 to -2.48; 84 eyes). The body of evidence for this outcome was of very low certainty, so we are uncertain about the effect of IPL on dry eye symptoms. There were no relevant combinable data for any of the other secondary outcomes, thus the effect of IPL on clinical parameters relevant to dry eye disease are currently unclear. For sodium fluorescein TBUT, two studies indicated that there may be an improvement in favour of IPL (MD 2.02 seconds, 95% CI 0.87 to 3.17; MD 2.40 seconds, 95% CI 2.27 to 2.53; 172 eyes total; low-certainty evidence). We are uncertain of the effect of IPL on non-invasive tear break-up time (MD 5.51 seconds, 95% CI 0.79 to 10.23; MD 3.20, 95% CI 3.09 to 3.31 seconds; two studies; 140 eyes total; very low-certainty evidence). For tear osmolarity, one study indicated that there may be an improvement in favour of IPL (MD -7.00 mOsmol/L, 95% -12.97 to -1.03; 56 eyes; low-certainty evidence). We are uncertain of the effect of IPL on meibomian gland orifice plugging (MD -1.20 clinical units, 95% CI -1.24 to -1.16; 84 eyes; very low-certainty evidence). We are uncertain of the effect of IPL on corneal sodium fluorescein staining. One study reported no evidence of a difference between the IPL and sham intervention arms at three months of follow-up (P = 0.409), and a second study reported data favouring IPL (MD -1.00 units, 95% CI -1.07 to -0.93 units; 172 eyes in total; very low-certainty evidence). We considered the incidence of adverse events at the study endpoint, as a measure of safety. As most trials did not specifically report adverse events, the safety of IPL as a treatment for MGD could also not be determined with any certainty. Very low-certainty results from individual studies suggest some adverse effects that may be experienced by participants, include mild pain and burning, and the potential for partially losing eyelashes (due to clinician error). AUTHORS' CONCLUSIONS: This systematic review finds a scarcity of RCT evidence relating to the effectiveness and safety of IPL as a treatment for MGD. Whether IPL is of value for modifying the symptoms or signs of evaporative dry eye disease is currently uncertain. Due to a lack of comprehensive reporting of adverse events, the safety profile of IPL in this patient population is also unclear. The current limitations in the evidence base should be considered by clinicians using this intervention to treat MGD, and outlined to individuals potentially undergoing this procedure with the intent of treating dry eye disease. The results of the 14 RCTs currently in progress will be of major importance for establishing a more definitive answer regarding the effectiveness and safety of IPL for treating MGD. We intend to update this review when results from these trials become available.

OBJECTIVE: To estimate the lifetime risk of primary shoulder arthroplasty in Australia and to examine changes over time. METHODS: For this retrospective population-level analysis, de-identified individual-level data on all primary partial shoulder arthroplasty (PSA) and total shoulder arthroplasty (TSA) procedures performed in Australia from 2008 to 2017 (n = 38,868) were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Population data and life tables were obtained from the Australian Bureau of Statistics. Lifetime risk of primary shoulder arthroplasty was calculated for each year using a standardized formula. Separate calculations were undertaken by sex and for PSA and TSA. RESULTS: The lifetime risk of shoulder arthroplasty increased significantly over time. For men, this risk more than doubled from 0.78% (95% confidence interval [95% CI] 0.73-0.84) in 2008 to 1.78% (95% CI 1.70-1.86) in 2017. Lifetime risk for women rose from 1.54% (95% CI 1.46-1.62) to 2.88% (95% CI 2.78-2.99) over the study period. This increase was predominantly driven by growth in lifetime risk of TSA. In contrast, lifetime risk of PSA decreased over time, from 0.25% (95% CI 0.22-0.28) in 2008 to 0.11% (95% CI 0.09-0.13) in 2017 for men, and from 0.55% (95% CI 0.51-0.60) to 0.11% (95% CI 0.09-0.13) for women. CONCLUSION: By the end of 2017, the lifetime risk of primary shoulder arthroplasty in Australia increased to 1 in 57 for men and 1 in 35 for women. Compared to declining PSA trends, there was substantial growth in TSA use over a decade. These data improve our understanding of the rising national burden of primary shoulder arthroplasty and can assist in planning to meet future surgical demand.

Irrespective of age, communication is a tool of expression and a key daily activity meeting the human need for social interaction and connection. The introduction of consumer-directed care (CDC) emphasises the importance of communication to provide consumers with the opportunity to exercise choice over the care they receive. As consumer-directed care progresses, it is hypothesised that the feasibility of shared decision-making and care planning in residential aged care will be largely determined by the communication opportunities afforded to the residents. Therefore, the aim of this study was to explore resident perceptions of the opportunities they have to communicate, including the opportunity to express their care preferences and contribute opinions about their care. A qualitative inductive design was adopted. An individual interview format was used to gather the perspectives of 102 residents. Data were analysed using qualitative content analysis to generate themes illustrating patterns in participant views. Overall, residents desired increased involvement in their care planning and increased opportunity for more meaningful communication and social opportunities. Residents described the negative impact of the communication difficulties they face on their communication and the need for support and activities to be tailored to residents' individual communication needs. To facilitate resident participation in CDC and meet resident desire for increased social communication, further investment in resources to support resident-staff communication and accommodate residents' individual communication needs is required. By highlighting communication as a stand-alone activity and a priority of residents, the findings of this study raise the profile of communication and demonstrate the need for explicit allocation of care time and specialist services to support resident-staff communication and social communication in residential aged care. Such support must be tailored to meet residents' individual communication needs and be coupled with increased staff training in providing communication support. Without facilitating resident communication and increasing the opportunity to communicate, shared decision-making and care planning in residential aged care consistent with person-centred and consumer-directed models of care will be limited.

Context Peripheral nerve damage can occur in a variety of systemic conditions and can have a profound impact on functional and psychological health. Currently, therapeutic interventions for peripheral nerve damage are limited. Objective The aim of this systematic review, conducted in accordance with the Cochrane Collaboration’s handbook and reported according to the PRISMA checklist, was to evaluate the efficacy and safety of omega-3 oral supplements for improving peripheral nerve structure and function. Data Sources PubMed, Embase, and Cochrane databases, along with clinical trial registries, were searched from inception to February 2019. Evidence was identified, critically appraised, and synthesized, and the certainty of evidence was appraised using the Grading of Recommendations Assessment, Development and Evaluation approach. Study Selection Randomized controlled trials assessing the effects of omega-3 oral supplementation on outcomes of peripheral nerve structure, peripheral nerve function, or both were eligible for inclusion. Titles and abstracts of identified articles were independently assessed for potential eligibility by 2 review authors. For studies judged as eligible or potentially eligible, full text articles were retrieved and independently assessed by 2 review authors to determine eligibility; disagreements were resolved by consensus. Data Extraction Fifteen trials were included. Two clinically similar studies that investigated the effect of omega-3 supplementation in individuals receiving chemotherapy were meta-analyzed. Pooled data showed a reduced incidence of peripheral neuropathy (RR = 0.58; 95%CI, 0.43–0.77) and a preservation of sensory nerve action potential amplitudes with omega-3 supplementation compared with placebo (MD = 4.19 µV; 95%CI; 2.19–6.19). Conclusion This review finds, with low certainty, that omega-3 supplementation attenuates sensory loss and reduces the incidence of neuropathy secondary to oxaliplatin and paclitaxel treatment relative to placebo. There is currently limited evidence to ascertain whether omega-3 supplementation is beneficial in other systemic conditions characterized by peripheral nerve damage.

This systematic review aimed to synthesise multimorbidity profiling literature to identify replicable and clinically meaningful groupings of multimorbidity. We searched six electronic databases (Medline, EMBASE, PsycINFO, CINAHL, Scopus, and Web of Science) for articles reporting multimorbidity profiles. The identified profiles were synthesised with multidimensional scaling, stratified by type of statistical analysis used in the derivation of profiles. The 51 studies that met inclusion criteria reported results of 98 separate analyses of multimorbidity profiling, with a total of 407 multimorbidity profiles identified. The statistical techniques used to identify multimorbidity profiles were exploratory factor analysis, cluster analysis of diseases, cluster analysis of people, and latent class analysis. Reporting of methodological details of statistical methods was often incomplete. The discernible groupings of multimorbidity took the form of both discrete categories and continuous dimensions. Mental health conditions and cardio-metabolic conditions grouped along identifiable continua in the synthesised results of all four methods. Discrete groupings of chronic obstructive pulmonary disease with asthma, falls and fractures with sensory deficits and of Parkinson’s disease and cognitive decline where partially replicable (identifiable in the results of more than one method), while clustering of musculoskeletal conditions and clustering of reproductive systems were each observed only in one statistical approach. The two most replicable multimorbidity profiles were mental health conditions and cardio-metabolic conditions. Further studies are needed to understand aetiology and evolution of these multimorbidity groupings. Guidelines for strengthening the reporting of multimorbidity profiling studies are proposed.

Objectives The Osteoarthritis Questionnaire (OA-Quest) is a new measure of individual burden of osteoarthritis, composing seven brief (4–11 items; total 42 items), independent scales. This study describes the psychometric evaluation of the OA-Quest. Specifically, temporal stability, convergent and discriminant validity, and responsiveness of the OA-Quest to joint replacement surgery were examined. Study Design and Setting Participants were drawn from rheumatology (n = 62), orthopedic (n = 90), and community (n = 175) settings. Temporal stability of the OA-Quest was evaluated over a 2-week period and was assessed with intraclass correlation coefficients. Responsiveness was assessed with standardized effect sizes and paired samples t-tests. Convergent and discriminant validity was assessed with a multitrait multimethod confirmatory factor analysis (MTMM CFA). Results The OA-Quest scales had high temporal stability, with intraclass correlation coefficients between 0.75 (lost productivity) and 0.94 (physical limitations) and showed improvements of expected magnitude and direction 3 months after joint replacement surgery, supporting their responsiveness. MTMM CFA supported the convergent and discriminant validity of the OA-Quest, demonstrated by adequate model fit (χ2 = 483.54, df = 184, P Conclusion The OA-Quest has strong evidence of temporal stability, construct validity, and is responsive to change following joint replacement surgery.

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:\ud \ud To assess whether blue-light filtering spectacle lenses impart effects on visual function, provide protection to the macula, or both. We will also examine potential effects on the sleep-wake cycle.

Background An intraocular lens (IOL) is a synthetic lens that is surgically implanted within the eye following removal of the crystalline lens, during cataract surgery. While all modern IOLs attenuate the transmission of ultra-violet (UV) light, some IOLs, called blue-blocking or blue-light filtering IOLs, also reduce short-wavelength visible light transmission. The rationale for blue-light filtering IOLs derives primarily from cell culture and animal studies, which suggest that short-wavelength visible light can induce retinal photoxicity. Blue-light filtering IOLs have been suggested to impart retinal protection and potentially prevent the development and progression of age-related macular degeneration (AMD). We sought to investigate the evidence relating to these suggested benefits of blue-light filtering IOLs, and to consider any potential adverse effects. Objectives To assess the effects of blue-light filtering IOLs compared with non-blue-light filtering IOLs, with respect to providing protection to macular health and function. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 9); Ovid MEDLINE; Ovid Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 25 October 2017. Selection criteria We included randomised controlled trials (RCTs), involving adult participants undergoing cataract extraction, where a blue-light filtering IOL was compared with an equivalent non-blue-light filtering IOL. Data collection and analysis The prespecified primary outcome was the change in distance best-corrected visual acuity (BCVA), as a continuous outcome, between baseline and 12 months of follow-up. Prespecified secondary outcomes included postoperative contrast sensitivity, colour discrimination, macular pigment optical density (MPOD), proportion of eyes with a pathological finding at the macula (including, but not limited to the development or progression of AMD, or both), daytime alertness, reaction time and patient satisfaction. We evaluated findings related to ocular and systemic adverse effects.Two review authors independently screened abstracts and full-text articles, extracted data from eligible RCTs and judged the risk of bias using the Cochrane tool. We reached a consensus on any disagreements by discussion. Where appropriate, we pooled data relating to outcomes and used random-effects or fixed-effect models for the meta-analyses. We summarised the overall certainty of the evidence using GRADE. Main results We included 51 RCTs from 17 different countries, although most studies either did not report relevant outcomes, or provided data in a format that could not be extracted. Together, the included studies considered the outcomes of IOL implantation in over 5000 eyes. The number of participants ranged from 13 to 300, and the follow-up period ranged from one month to five years. Only two of the studies had a trial registry record and no studies referred to a published protocol. We did not judge any of the studies to have a low risk of bias in all seven domains. We judged approximately two-thirds of the studies to have a high risk of bias in domains relating to 'blinding of participants and personnel' (performance bias) and 'blinding of outcome assessment' (detection bias).We found with moderate certainty, that distance BCVA with a blue-light filtering IOL, at six to 18 months postoperatively, and measured in logMAR, was not clearly different to distance BCVA with a non-blue-light filtering IOL (mean difference (MD) -0.01 logMAR, 95% confidence interval (CI) -0.03 to 0.02, P = 0.48; 2 studies, 131 eyes).There was very low-certainty evidence relating to any potential inter-intervention difference for the proportion of eyes that developed late-stage AMD at three years of follow-up, or any stage of AMD at one year of follow-up, as data derived from one trial and two trials respectively, and there were no events in either IOL intervention group, for either outcome. There was very low-certainty evidence for the outcome for the proportion of participants who lost 15 or more letters of distance BCVA at six months of follow-up; two trials that considered a total of 63 eyes reported no events, in either IOL intervention group.There were no relevant, combinable data available for outcomes relating to the effect on contrast sensitivity at six months, the proportion of eyes with a measurable loss of colour discrimination from baseline at six months, or the proportion of participants with adverse events with a probable causal link with the study interventions after six months.We were unable to draw reliable conclusions on the relative equivalence or superiority of blue-light filtering IOLs versus non-blue-light filtering IOLs in relation to longer-term effects on macular health. We were also not able to determine with any certainty whether blue-light filtering IOLs have any significant effects on MPOD, contrast sensitivity, colour discrimination, daytime alertness, reaction time or patient satisfaction, relative to non-blue-light filtering IOLs. Authors' conclusions This systematic review shows with moderate certainty that there is no clinically meaningful difference in short-term BCVA with the two types of IOLs. Further, based upon available data, these findings suggest that there is no clinically meaningful difference in short-term contrast sensitivity with the two interventions, although there was a low level of certainty for this outcome due to a small number of included studies and their inherent risk of bias. Based upon current, best-available research evidence, it is unclear whether blue-light filtering IOLs preserve macular health or alter risks associated with the development and progression of AMD, or both. Further research is required to fully understand the effects of blue-light filtering IOLs for providing protection to macular health and function.

INTRODUCTION AND AIMS: The study investigates the prevalence of pre-drinking culture in the night-time economy (NTE) and its impact upon intoxication and alcohol-related harm and violence experienced by patrons. DESIGN AND METHODS: Cross-sectional surveys were conducted in and around licensed venues in Newcastle (NSW) and Geelong (Victoria) during peak trading hours (typically 9pm-1am). Participants completed a five minute structured interview which targeted: demographics, past and planned movements on the survey night, safety/experience of harm, and patron intoxication. 3949 people agreed to be interviewed, a response rate of 90.7%. Around half (54.9%) of interviewees were male and mean age was 24.4 years (SD = 5.8). RESULTS: 66.8% of participants reported pre-drinking prior to attending licensed venues. On a 1-10 scale measuring self-rated intoxication, pre-drinkers scored significantly higher compared to non pre-drinkers (P DISCUSSION AND CONCLUSIONS: 'Pre-drinking' was normal behaviour in the current sample and contributes significantly to the burden of harm and intoxication in the NTE. Price disparity between packaged vs. venue liquor is a key motivator for pre-drinking. KW: Pregaming Language: en

BACKGROUND: There is a paucity of studies evaluating targeted obesity prevention interventions in pre-school children. OBJECTIVES: We conducted a randomized controlled trial to evaluate the efficacy of a parent-based obesity prevention intervention for pre-schoolers - MEND (Mind, Exercise, Nutrition … Do It!) 2-4 on child diet, eating habits, physical activity/sedentary behaviours, and body mass index (BMI). METHODS: Parent-child dyads attended 10 weekly 90-min workshops relating to nutrition, physical activity and behaviours, including guided active play and healthy snack time. Assessments were conducted at baseline, immediately post-intervention, and 6 and 12 months post-intervention; child intake of vegetables, fruit, beverages, processed snack foods, fussiness, satiety responsiveness, physical activity, sedentary behaviour and neophobia were assessed via parent proxy report. Parent and child height and weight were measured. RESULTS: Two hundred one parent-child dyads were randomized to intervention (n = 104) and control (n = 97). Baseline mean child age was 2.7 (standard deviation [SD] 0.6) years, and child BMI-for-age z-score (World Health Organization) was 0.66 (SD 0.88). We found significant positive group effects for vegetable (P = 0.01) and snack food (P = 0.03) intake, and satiety responsiveness (P = 0.047) immediately post-intervention. At 12 months follow-up, intervention children exhibited less neophobia (P = 0.03) than controls. CONCLUSION: Future research should focus on additional strategies to support parents to continue positive behaviour change. ACTRN12610000200088.

There is now a considerable body of research investigating inequities in access to health care for arthritis according to socioeconomic status (SES). Conducted in a range of settings internationally, studies have examined specific socioeconomic factors (including education, income, deprivation and health insurance status) in relation to access to treatment. This chapter provides a comprehensive review of the available evidence on disparities in access to self-management education, conservative therapy and surgical treatment for arthritis, according to SES. There is some evidence of SES disparities in access to self-management education and advice, primary care, specialist care, physical therapy and medications, and strong evidence that people with less education or lower income experience significant disparities in access to joint replacement surgery. In view of research indicating that disparities may adversely affect patient outcomes, examples of initiatives designed to optimise access to care for disadvantaged groups are also described.

Both time of the day and season have been shown to have a significant effect on stroke incidence. In contrast, the role played by the moon has been little studied. We aimed to investigate the potential association of the lunar phase with the incidence of stroke subtypes [intracerebral hemorrhage (ICH), transient ischemic attack (TIA) and ischemic stroke (IS)], adjusted by circadian and seasonal variations. Consecutive stroke admissions to the Royal Melbourne Hospital (RMH) were analyzed from 2004–2011. Of 6252 patients, 4085 (65.3%) had confirmed dates and hour of the day. Of these, 632 (15.5%) had ICH, 658 (16.1%) presented with TIA and 2202 (53.9%) had IS. There were also 593 (14.5%) stroke mimics. We measured the association of stroke incidence with a particular lunar phase using an incidence rate ratio (IRR) with 95% confidence intervals (CI) using Poisson regression model (new moon set as reference). Compared with new moon phase, ICHs occurred significantly more during the first quarter (IRR, 1.55; 95%CI, 1.04 to 2.30; p = 0.03). More TIAs were observed during the first quarter and full moon than in new moon (IRR, 1.69; 95%CI, 1.16 to 2.46; p = 0.01; IRR, 1.52; 95%CI, 0.00 to 2.31; p = 0.05; respectively). Both ICH and TIA occurrence slightly decreased as lunar illumination increased (IRR, 0.99; 95%CI, 0.99 to 1.00; p = 0.01; IRR, 0.99; 95%CI, 0.99 to 1.00; p = 0.04; respectively). No association was found between lunar phase or illumination and IS. All stroke subtypes were less likely to happen between 12AM and 6AM than the remaining 18 h of the day. IS occurrence was significantly higher during the spring than summer (IRR, 1.14; 95%CI, 1.02 to 1.28; p = 0.03). For the patients older than 65 years, incidence of both ICH and IS was higher in spring than in summer (IRR, 1.33; 95%CI, 1.01 to 1.74; p = 0.04; IRR, 1.22; 95%CI, 1.06 to 1.39; p = 0.005; respectively). The lunar phase and illumination are associated with both ICH and TIA incidence. These findings should be tested on other stroke databases.
