Background: Low back pain is highly prevalent and the main cause of years lived with disability (YLDs). We present the most up-to-date global, regional, and national data on prevalence and YLDs for low back pain from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021. Methods: Population-based studies from 1980 to 2019 identified in a systematic review, international surveys, US medical claims data, and dataset contributions by collaborators were used to estimate the prevalence and YLDs for low back pain from 1990 to 2020, for 204 countries and territories. Low back pain was defined as pain between the 12th ribs and the gluteal folds that lasted a day or more; input data using alternative definitions were adjusted in a network meta-regression analysis. Nested Bayesian meta-regression models were used to estimate prevalence and YLDs by age, sex, year, and location. Prevalence was projected to 2050 by running a regression on prevalence rates using Socio-demographic Index as a predictor, then multiplying them by projected population estimates. Findings: In 2020, low back pain affected 619 million (95% uncertainty interval 554–694) people globally, with a projection of 843 million (759–933) prevalent cases by 2050. In 2020, the global age-standardised rate of YLDs was 832 per 100 000 (578–1070). Between 1990 and 2020, age-standardised rates of prevalence and YLDs decreased by 10·4% (10·9–10·0) and 10·5% (11·1–10·0), respectively. A total of 38·8% (28·7–47·0) of YLDs were attributed to occupational factors, smoking, and high BMI. Interpretation: Low back pain remains the leading cause of YLDs globally, and in 2020, there were more than half a billion prevalent cases of low back pain worldwide. While age-standardised rates have decreased modestly over the past three decades, it is projected that globally in 2050, more than 800 million people will have low back pain. Challenges persist in obtaining primary country-level data on low back pain, and there is an urgent need for more high-quality, primary, country-level data on both prevalence and severity distributions to improve accuracy and monitor change.

Objective This scoping review aimed to comprehensively review strategies for implementation of low back pain (LBP) guidelines, policies, and models of care in the Australian health care system. Methods A literature search was conducted in MEDLINE, EMBASE, CINAHL, Allied and Complementary Medicine Database, and Web of Science to identify studies that aimed to implement or integrate evidence-based interventions or practices to improve LBP care within Australian settings. Results Twenty-five studies met the inclusion criteria. Most studies targeted primary care settings (n = 13). Other settings included tertiary care (n = 4), community (n = 4), and pharmacies (n = 3). One study targeted both primary and tertiary care settings (n = 1). Only 40% of the included studies reported an underpinning framework, model, or theory. The implementation strategies most frequently used were evaluative and iterative strategies (n = 14, 56%) and train and educate stakeholders (n = 13, 52%), followed by engage consumers (n = 6, 24%), develop stakeholder relationships (n = 4, 16%), change in infrastructure (n = 4, 16%), and support clinicians (n = 3, 12%). The most common implementation outcomes considered were acceptability (n = 11, 44%) and adoption (n = 10, 40%), followed by appropriateness (n = 7, 28%), cost (n = 3, 12%), feasibility (n = 1, 4%), and fidelity (n = 1, 4%). Barriers included time constraints, funding, and teamwork availability. Facilitators included funding and collaboration between stakeholders. Conclusions Implementation research targeting LBP appears to be a young field, mostly focusing on training and educating stakeholders in primary care. Outcomes on sustainability and penetration of evidence-based interventions are lacking. There is a need for implementation research guided by established frameworks that consider interrelationships between organizational and system contexts beyond the clinician–patient dyad.

Background Chronic pain is a major and growing public health issue. Multidisciplinary tertiary pain services cannot meet patient demand and greater involvement of primary care is needed. The aims of this study were to understand the needs and priorities of Australian primary health networks (PHNs) related to the management and secondary prevention of chronic pain; map current PHN chronic pain initiatives and identify gaps; highlight key enablers to implementation; and highlight solutions identified by PHNs to increase capacity to commission initiatives. Methods Mixed methods were used, including: a review of PHN needs assessments; and consultation with PHN executive-level staff and program managers from 27 out of the 28 PHNs, and the WA Primary Health Alliance (WAPHA – a state alliance between three Western Australian PHNs) via telephone interviews, online surveys, a workshop, a deliberative dialogue and email consultation. Results Chronic pain was identified as a health and/or service need by approximately half of PHNs. Barriers for PHNs to identifying chronic pain as a need or priority are highlighted. Gaps identified by the mapping included: initiatives related to the secondary prevention of chronic pain (post-surgery or post-injury), digitally enabled consumer and health professional chronic pain initiatives, and chronic pain initiatives for specific populations groups such as Aboriginal and Torres Strait Islander people. Among existing PHN practice, two exemplar evidence-based initiatives suitable for scale-up across PHNs in Australia were identified: multidisciplinary community-based pain programs, and an online health professional capacity-building initiative, Project ECHO (chronic pain). Solutions identified by PHNs to increase capacity to commission initiatives included: co-funding initiatives across different PHN funding streams, collaborative initiatives between PHNs, and co-commissioning with government and non-government partners. Conclusions Chronic pain has been classified as a disease in itself through the World Health Organization. PHNs recognising chronic pain as a distinct condition in PHN needs analysis and data collection would lead to more dedicated funding. PHNs could do more to improve the secondary prevention and management of chronic pain. A self-identified need for greater collaboration across PHNs and co-commissioning with local and state governments and non-government partners would help to build PHN capacity.

Anemia is associated with increased risk of all-cause mortality in older populations. However, the relationship between hemoglobin and major adverse cardiovascular events (MACE), and whether this is modulated by frailty, is unclear.CHAMP (Concord Health and Ageing in Men Project) is a prospective study of community-dwelling men aged ≥ 70 years. The relationship between hemoglobin and 7-year MACE was analysed by means of Cox regression. The Youden index was used to determine the optimal hemoglobin cutoff point in predicting MACE. Frailty was assessed with the use of the Fried criteria.The cohort comprised 1604 men (mean ± SD age 76.9 ± 5.5 years). Decreasing hemoglobin was associated with increased comorbidity, frailty, and MACE (P0.001), with 140 g/L the optimal cutoff point for predicting MACE. Hemoglobin, age, and frailty independently predicted MACE (all P0.001). Each 10 g/L decrement in hemoglobin level was associated with increased risk of MACE (hazard ratio [HR] 1.13, 95% confidence interval [CI] 1.06-1.20; P0.001), all-cause mortality (HR 1.20, 95% CI 1.12-1.29; P0.001), cardiovascular mortality (HR 1.07, 95% CI 1.01-1.14; P = 0.025), myocardial infarction (HR 1.17, 95% CI 1.09-1.25; P0.001), and heart failure (HR 1.17, 95% CI 1.09-1.25; P0.001). When stratified into hemoglobin quintiles, men in the lowest 2 quintiles (Hb 133-140 g/L and132g/L, respectively) were at increased risk of MACE, cardiovascular mortality, myocardial infarction, and heart failure (all P0.05). This relationship for MACE was independent from frailty status, with the test for interaction between frailty and hemoglobin not reaching significance (P = 0.24).Low hemoglobin was associated with increased MACE in community-dwelling older men independently from frailty. A hemoglobin cutoff point of 140 g/L, a level that is above contemporary definitions of anemia, predicted long-term MACE.

Introduction: This study aimed to assess the extent to which a single item of self-reported hearing difficulties is associated with future risk of falling among community-dwelling older adults. Methods: We used data from two Australian population-based cohorts: three waves from the PATH Through Life study (PATH; n = 2,048, 51% men, age 66.5 ± 1.5 SD years) and three waves from the Concord Health and Ageing in Men Project (CHAMP; n = 1,448, 100% men with mean age 77.3 ± 5.3 SD years). Hearing difficulties were recorded on a four-point ordinal scale in PATH and on a dichotomous scale in CHAMP. The number of falls in the past 12 months was reported at each wave in both studies. In CHAMP, incident falls were also ascertained by triannual telephone call cycles for up to four years. Multivariable-adjusted random intercept negative binomial regression models were used to estimate the association between self-reported hearing difficulties and number of falls reported at the following wave or 4-monthly follow-ups. Results: In PATH, self-reported hearing difficulties were associated with a higher rate of falls at follow-up (incidence rate ratio = 1.15, 95% CI = 1.03–1.27 per a one-level increase in self-reported hearing difficulties), after adjusting for sociodemographic characteristics, health behaviours, physical functioning, balance, mental health, medical conditions, and medications. There were no significant associations between hearing difficulties and the rate of falls based on either repeated survey or 4-monthly follow-ups in CHAMP. Conclusion: Though we find mixed results, findings from PATH data indicate an ordinal measure of self-reported hearing loss may be predictive of falls incidence in young-old adults. However, the null findings in the male-only CHAMP preclude firm conclusions of a link between hearing loss and falls risk.

Background The association between dietary protein intake and the risk of mortality is still controversial. The present study aimed to examine the associations between dietary total, animal and plant protein intake and all-cause and cause-specific mortality. Methods Community-dwelling men aged ≥ 70 years were recruited from local government areas surrounding Concord Hospital in Sydney, New South Wales for the Concord Health and Ageing in Men Project (CHAMP). The research dietitian administered a standardised validated diet history questionnaire to capture baseline dietary intake. In total, 794 men participated in a detailed diet history interview at the third wave. Adequacy of protein intake was assessed by comparing participant intake with the Nutrient Reference Values. Total protein intake was categorised into quintiles. Sources of protein were also captured. Mortality was ascertained through the New South Wales death registry. Cox proportional hazard models were used to assess the association between dietary total, animal and plant protein intake and risk of mortality. Results The mean age of the CHAMP men was 81 years. In total, 162 men died during a median follow-up of 3.7 years. Of these, 54 (33.3%) and 49 (30.2%) men died due to cancer and cardiovascular disease, respectively. There were U-shaped associations between protein intake and all-cause and cancer mortality. In multiple adjusted analysis, the second (hazard ratio [HR] = 0.38; 95% confidence interval [CI] = 0.18-0.82) and third (HR = 0.36; 95% CI = 0.16-0.82) quintiles of protein intakes were significantly associated with reduced risk of all-cause and only second quintile (HR = 0.47; 95% CI = 0.10-0.93) of protein intake was significantly associated with cancer mortality. Each serve increase in animal protein was significantly associated with 12% (HR = 1.12; 95% CI = 1.00-1.26) and 23% (HR = 1.23; 95% CI = 1.02-1.49) increased risk of all-cause mortality and cancer mortality respectively. Conversely, each serve increase in plant protein intake was significantly associated with 25% (HR = 0.75; 95% CI 0.61-0.92) and 28% (HR = 0.72; 95% CI = 0.53-0.97) reduced risk of all-cause and cancer mortality, respectively. No such associations were observed for cardiovascular disease mortality. Conclusions Both second and third quintiles of total protein intake were associated with reduced all-cause and cancer mortality. Plant protein was inversely associated with all-cause and cancer mortality, whereas animal protein intake was positively associated with mortality.

Low back pain (LBP) directives provide information about how LBP should be managed, communicated and navigated in complex health systems, making them an important form of policy. This study aimed to examine how LBP is problematised (represented) in Australian directives.We employed an analysis of discourse of LBP directives drawing on Bacchi'sOur analysis suggests that LBP is problematised as a symptom that tends to improve when individuals take responsibility for themselves, but may require care at times. The way in which LBP is represented in the directives excludes important aspects, such as the uncertainties of scientific knowledge, paradigms other than (post)positivist, multimorbidity, social and structural determinants of health.LBP directives may benefit from problematisations of LBP that consider the ongoing nature of LBP and broader contextual factors that impact on both LBP outcomes and care, beyond individual responsibility. Consideration of a wider range of paradigms and expanded evidence base may also be beneficial, as these are likely to enable individuals, clinicians and the Australian healthcare system to address LBP while dealing with its complexities, enabling real-world changes to lessen the LBP burden.IMPLICATIONS FOR REHABILITATIONHealthcare professionals who work with people who experience low back pain (LBP) may benefit from critically reflecting about discourses embedded in policy directives.Healthcare professionals may consider engaging in policy changes processes to expand the discourses on which LBP policy directives rely.Healthcare professionals' ability to enact policy recommendations may be enhanced by consideration of the fluctuating nature of LBP, uncertainties, multimorbidity and determinants of health.

Objective:Inadequate nutrient intakes have been linked with poor dentition in older adults. The aim of this study was to investigate the associations between the composition of functional tooth units (FTU) and nutrient intakes in older men.Design:A cross-sectional study with a standardised validated diet history assessment and comprehensive oral health assessments. FTU were categorised by dentition type: (i) Group A (Natural FTU Only), (ii) Group B (Natural and Replaced FTU) and (iii) Group C (No Natural FTU). Attainment of nutrient reference values (NRV) for sixteen micronutrients was incorporated into a micronutrient risk variable, dichotomised ‘good’ (≥ 12) or ‘poor’ (≤ 11), and for seven macronutrients into a macronutrient risk variable, dichotomised ‘good’ (≥ 5) or ‘poor’ (≤ 4).Setting:Subjects selected from the local Sydney geographical areas.Participants:Community-dwelling older men (n 608).Results:32 % (n 197) of participants were categorised as Group A, 27 % (n 167) as Group B and 40 % (n 244) as Group C. In adjusted logistic regression analysis, being in Group C, compared with Group A, was associated with intakes below NRV recommendations for fibre (OR: 2·30, 95 % CI 1·30, 4·05). Adjusted analysis also showed that men in Group C, compared with Group A, were more likely to have poor intake of macronutrients (OR: 2·00, 95 % CI 1·01, 3·94).Conclusions:Our study shows statistically significant associations between the composition of FTU and poor macronutrient intakes. Maintaining natural pairs of occluding FTU may be important for attaining adequate nutrient intakes in older men.

Deprescribing is the systematic process of discontinuing drugs when harms outweigh the benefits. We conducted semistructured telephone interviews with 22 general practitioners (GPs) who had prescribed or deprescribed opioids in patients with chronic noncancer pain within the past 6 months to investigate the barriers and facilitators to deprescribing opioid analgesics in patients with chronic noncancer pain. We also explored GPs' perspectives on the available resources to assist them with opioid deprescribing. Interviews were audio-recorded, transcribed verbatim, and then coded using an iterative process until data saturation reached. The thematic analysis process identified themes, first as concepts, and then refined to overarching themes after the merging of similar subthemes. Themes exploring barriers to deprescribing highlighted the difficulties GPs face while considering patient factors and varying prescribing practices within the confines of the health system. Patient motivation and doctor-patient rapport were central factors to facilitate deprescribing and GPs considered the most important deprescribing resource to be a multidisciplinary network of clinicians to support themselves and their patients. Therefore, although GPs emphasised the importance of deprescribing opioid analgesics, they also expressed many barriers relating to managing complex pain conditions, patient factors, and varying prescribing practices between clinicians. Some of these barriers could be mitigated by GPs having time and resources to educate and build rapport with their patients. This suggests the need for further development of multimodal resources and improved support through the public health system to enable GPs to prioritise patient-centred care.

Background Unintended weight loss and the reduction in appetite are common phenomenon among older people. Reduced appetite has been linked to medication related reductions in saliva production, reduced taste ability and poor oral health. Poor appetite can result in reduced nutrient intake ensuing weight loss. It is possible that poor appetite is a mediating step on the causal pathway between oral health and weight loss. This study investigates whether poor oral health and loss of appetite are related to weight loss. Methods This is an observational study where data were obtained from the Concord Health and Ageing in Men Project (CHAMP). Information on socio-demographics, appetite and health related behavior was collected by self-completed questionnaire. Intraoral assessment was conducted by calibrated oral health therapists. Height and weight were measured by trained staff. Regression analysis investigated associations between oral health and appetite as risk factors for weight loss. Results Participants included 542 community dwelling older males. 99 older men (18.3%) experienced 5% or more weight loss over 3 years. Men who lost weight from baseline had lower BMI and lower body weight, had higher prevalence of frailty and depression, reported poorer appetite, and had fewer teeth (13.8 ± 9.5) than those who did not lose weight (16.3 ± 9.3). Before adjustment, the prevalence ratio (PR) for weight loss was 1.76 (95% Confidence Interval (CI), 1.19–2.59) for participants with 0–19 natural teeth present compared to those with 20 or more teeth. When adding appetite and other variables to the model, the PR for number of teeth and weight loss was unchanged: 1.78 (95% CI, 1.06–3.00). The mediation analysis showed that the indirect effect of appetite on the association between number of natural teeth on weight loss was not found to be significant. Conclusion This study found that number of natural teeth present and appetite are independently related to weight change among elderly men in Australia. Tooth loss can increase the risk of swallowing difficulty leading to change in food preference, avoidance of foods and a decrease in energy intake. Our study showed the importance of oral health interventions to encourage maintenance of 20 or more natural teeth in older people.

The role of antioxidant intake in cardiovascular disease remains inconclusive. This study evaluates the association between antioxidant intake and the risk of major adverse cardiovascular events (MACE) among older Australian men.794 men aged ≥75 years participated in the 3rd wave of the Concord Health and Ageing in Men Project. Dietary adequacy of antioxidant intake was assessed by comparing participants' intake of vitamins A, E, C and zinc to the Nutrient Reference Values (NRV) for Australia. Attainment of NRVs of antioxidants was categorised into a dichotomised variable 'inadequate' (meeting≤2 of 4 antioxidants) or 'adequate' (meeting≥3 of 4 antioxidants). The usage of antioxidant supplements was assessed. The outcome measure was MACE. The composite MACE endpoint was defined as having one of the following: death, myocardial infarction, ischemic stroke, congestive cardiac failure (CCF), and revascularization during the period of observation. There was no significant association between dietary (HR: 1.03, 95% CI: 0.71, 1.48) or supplemental antioxidant intake (HR: 1.10, 95% CI: 0.75, 1.63) and overall MACE. However, a significant association was observed between inadequate antioxidant intake and CCF (HR: 1.32; 95% CI: 1.16, 1.50). The lowest quartile of zinc intake (11.00 mg/d) was significantly associated with CCF (HR 2.36; 95% CI: 1.04, 5.34). None of the other antioxidants were significantly associated with CCF or other MACE components.Inadequate dietary antioxidant intake, particularly zinc, is associated with increased risk of CCF in older Australian men but not associated with overall MACE.

BACKGROUND/OBJECTIVES To compare the Australian Dietary Guideline Index (DGI-2013) and the Pyramid-based Mediterranean Diet Score (pyrMDS) as measures of diet quality in an ethnically diverse group of older men. SUBJECTS/METHODS Seven hundred and ninety-four older men aged ≥75 participated in wave 3 (2012-2013) of the Concord Health and Ageing in Men Project. Dietary intake was assessed using a validated diet history questionnaire. Ethnicity was based on self-reported country of birth and categorised as Australian-born (418 men), Italian or Greek migrants (188), and other migrants (188). Incident cardiovascular outcomes until March 2018 were measured using the composite of major adverse cardiovascular events (MACE), which comprises all-cause mortality, acute myocardial infarction, congestive cardiac failure, coronary revascularisation and/or ischaemic stroke. Ability to predict incident cardiovascular outcomes and all-cause mortality were compared between standardised DGI-2013 pyrMDS scores by comparison of hazard ratios, discrimination (Harrell's C-statistic) and calibration (calibration plots). RESULTS Italian and Greek migrant men had significantly lower DGI-2013 scores (91.7 vs. 93.9; p = 0.01) but significantly higher pyrMDS scores (8.8 vs. 8.2; p

Although characteristic changes in amino acid concentrations occur in obesity and sarcopenia, amino acids concentrations have not been reported in sarcopenic obesity. We studied n = 831 men aged 75 years and older from the 5-year follow-up of the Concord Health and Ageing in Men Project. Sarcopenia was defined using the Foundation of the National Institutes of Health criteria and obesity was defined as >30% fat mass. There were 31 men (3.7%) who had sarcopenic obesity. Branched chain amino acids were elevated in the obese (but not sarcopenic) group (n = 348) but reduced in both the sarcopenic (but not obese) (n = 44) and the sarcopenic obese groups. Apart from this, most of the amino acid concentrations were between those for the obese and the sarcopenic groups. Yet despite low concentrations of branched chain amino acids, the sarcopenic obese group had indications of insulin resistance and diabetes mellitus (fasting glucose and insulin concentrations, homeostatic model assessment, and percentage of participants taking diabetes medications) that were similar to the obese group. In summary, sarcopenic obese participants did not have a unique amino acid signature. In obesity, elevated branched chain amino acids are not a prerequisite for insulin resistance and diabetes if obesity is associated with sarcopenia.

Pregabalin has become widely used as an alternative to opioids in treating certain types of chronic non-cancer pain, but few studies have examined its clinical efficacy outside trials. We address this gap by examining the utilization, correlates and clinical outcomes of pregabalin use among an Australian community-based cohort of people prescribed opioids for chronic non-cancer pain. Through a five-year prospective cohort study (n = 1514) we examined associations between pregabalin use and pain severity and interference, mental health, opioid dose and past month use of ambulance and emergency department services. We used fixed-effects regression models to examine within-participant differences, and random-effects regression models to examine within and between participant differences in clinical outcomes. In an analysis of cases with complete data over five-years (n = 896), the prevalence of pregabalin use ranged from 16% at cohort entry to 29% at 36- and 48-months, and 46% reported pregabalin use at any time during the five years.. Pregabalin use was associated with greater pain severity and interference and greater use of high-risk opioid doses (>90 oral morphine equivalents/day). Pregabalin use was not associated with changes in mental health symptoms, ambulance, or emergency department attendance in the fixed or random effects models. Pregabalin use was common, but for most people use was not associated with clinically meaningful improvements in pain or functioning.

High-impact physical activities with bone strains of high magnitude and frequency may benefit bone health. This study aimed to investigate the longitudinal associations between changes in loading intensities and application rates, estimated from self-reported physical activity, with bone mineral density (BMD) changes over 5 years and also with incident falls over 2 years and long-term incident fractures in community-dwelling older men. A total of 1599 men (mean age 76.8 ± 5.4 years) from the Concord Health and Aging in Men Project (CHAMP) were assessed at baseline (2005-2007) and at 2- and 5-year follow-up. At each time point, hip and lumbar spine BMD were measured by dual-energy X-ray absorptiometry, and physical activity energy expenditure over the past week was self-reported via the Physical Activity Scale for the Elderly (PASE) questionnaire. Sum effective load ratings (ELRs) and peak force were estimated from the PASE questionnaire, reflecting the total and highest loading intensity and application rate of physical activities, respectively. Participants were contacted every 4 months over 2 years to self-report falls and over 6.0 ± 2.2 years for fractures. Hip fractures were ascertained by data linkage for 8.9 ± 3.6 years. Compared with sum ELR and PASE scores, peak force demonstrated the greatest standardized effect size for BMD maintenance at the spine (β = 9.77 mg/cm2 ), total hip (β = 14.14 mg/cm2 ), and femoral neck (β = 13.72 mg/cm2 ) after adjustment for covariates, including PASE components (all p

Objective To assess the associations between nutrient intake and dietary patterns with different sarcopenia definitions in older men. Design Cross-sectional study. Setting Sarcopenia was defined using the Foundation for the National Institutes of Health (FNIH), the European Working Group on Sarcopenia in Older People (EWGSOP) and the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). Dietary adequacy of fourteen nutrients was assessed by comparing participants' intakes with the Nutrient Reference Values (NRV). Attainment of NRV for nutrients was incorporated into a variable 'poor' (meeting ≤ 9) v. 'good' (meeting ≥ 10) using the cut-point method. Also, two different dietary patterns, monounsaturated:saturated fat and n-6:n-3 fatty acids ratio and individual nutrients were used as predictor variables. Participants A total of 794 men aged ≥75 years participated in this study. Results The prevalence of sarcopenia by the FNIH, EWGSOP and EWGSOP2 definitions was 12·9 %, 12·9 % and 19·6 %, respectively. With the adjustment, poor nutrient intake was significantly associated with FNIH-defined sarcopenia (OR: 2·07 (95 % CI 1·16, 3·67)), but not with EWGSOP and EWGSPOP2 definitions. The lowest and second-lowest quartiles of protein, Mg and Ca and the lowest quartiles of n-6 PUFA and n-3 PUFA intakes were significantly associated with FNIH-defined sarcopenia. Each unit decrease in n-6:n-3 ratio was significantly associated with a 9 % increased risk of FNIH-defined sarcopenia (OR: 1·09 (95 % CI 1·04, 1·16)). Conclusions Inadequate intakes of nutrients are associated with FNIH-defined sarcopenia in older men, but not with the other two sarcopenia definitions. Further studies are required to understand these relationships.

Across the world, pain treatment centres have closed their doors. Because of the COVID-19 pandemic, healthcare providers are abruptly changing their care delivery to protect patients and staff from infection and to reallocate resource towards the greatest acute needs. Elective, routine, and nonemergency casework has stopped in secondary and tertiary centres, while in primary care, patients are requested to stay away or “socially distance,” and in residential care facilities and hospices, strict isolation and separation protocols have been introduced. Before the COVID-19 pandemic, telemedicine and eHealth approaches were being developed and tested in a gradual fashion with many studies focusing on lessons learned and barriers to using digital solutions.3,37,39,51 Overnight, however, treating or supporting people with non-urgent and long-term conditions at a distance from healthcare providers has become imperative. These immediate changes are happening across healthcare systems. Telemedicine is being used to demand-manage the flow of patients with respiratory distress accessing emergency departments25; video consultation is being introduced in multiple settings23; and using social media is being discussed positively for its potential to direct people to trusted resources, to counteract misinformation, and to provide psychological first aid.36 Pain management providers face the challenge of delivering face-to-face service through different modes. Fortunately, there is a rich stream of research and clinical experience in the use of different technological solutions. Table ​Table11 provides a summary of the definitions and terminology in use. Table 1 Definitions and terminology used in remotely supported pain management.

Background Several studies have examined the relationship between cognition and oral health in older populations. To further understand this relationship, we examined the associations between cognitive function, chewing capacity and the number of teeth present in community-dwelling older males in Australia. Methods Data were obtained from cross-sectional analysis of fourth wave of the Concord Health and Ageing in Men Project (CHAMP). Participants were 369 community-dwelling males aged 78 years or over. Cognitive function was measured utilising the Mini-Mental State Examination (MMSE). Chewing capacity was determined on ability to chew food items of different textures, and oral health data were collected. Ordinal regression was used to analyse associations between MMSE (four categories) and chewing capacity and number of natural teeth present. Results Overall, 67.5% of participants reported that they could chew all 11 listed food items. Participants with fewer than 20 teeth were statistically significantly more likely to have cognitive impairment (unadjusted odds ratio (OR) 1.87; 95% confidence interval (CI) 1.25-2.79, adjusted OR 1.62; 95% CI 1.07-2.43). Participants with limited chewing capacity were also more likely to have cognitive impairment (unadjusted OR 1.91; 95% CI 1.25-2.94, adjusted OR 1.61; 95% CI 1.03-2.49). Conclusions This study suggests either that older men with fewer than 20 natural teeth and those with limited chewing capacity are more likely to have an associated cognitive impairment or that those with cognitive impairment are more likely to have fewer teeth and limited chewing capacity. Further longitudinal studies should clarify these relationships.

Objectives The types of medical conditions leading to hospitalization in frail older people have not been investigated. The objectives were to evaluate associations between frailty and (a) risk of all-cause and cause-specific hospitalization, and (b) rate of all-cause and cause-specific hospitalizations. Design, Setting and Participants Community-dwelling men aged 70+ years in the Concord Health and Ageing in Men Project (CHAMP) were assessed for frailty at baseline (2005–2007, n=1705). Measurements Frailty was determined by both the Fried frailty phenotype (FP) and the Rockwood frailty index (FI). Non-elective and elective hospitalization data were accessed from the New South Wales (NSW) Admitted Patient Data Collection and mortality from the NSW Deaths Registry for the period 2005–2017. Causes of hospitalization were categorized using ICD-10 classification of principal diagnoses based on organ system involved into 14 major categories. Results Nearly 80% of CHAMP men had at least one non-elective hospitalization and 63% had an elective hospitalization over a 9-year follow-up. Men with FP frailty were twice as likely to have a non-elective hospitalization (HR: 1.98, 95%CI: 1.61–2.44) and a greater number of non-elective hospitalizations (IRR: 1.44, 95%CI: 1.22-1.70). Similar relationships were found between FI frailty and non-elective hospitalizations. Men with frailty (either FP or FI) were more likely to have at least one non-elective hospitalization for 13 of the 14 cause-related admissions. In contrast, frailty was only associated with 3 cause-related elective hospitalizations. Men with frailty were also more likely to have an increased number of non-elective hospitalizations for all 14 causes, but only for 6 causes of elective hospitalizations. Conclusions Our findings suggest frailty increases the risk and number of non-elective hospitalizations in older men for a wide range of cause. Strategies on early identification of frailty, followed by appropriate preventative strategies to lower the risk of non-elective hospital admissions are warranted.

Objective To determine, in a population based linked data study, the relationship between peri-operative multiple complications and longer term outcomes, specifically the combined outcome of two year amputation or death, after lower limb revascularisation for peripheral artery disease (PAD). Methods State wide health administrative data and death records were probabilistically linked for all patients who had lower limb artery surgery between 2010 and 2012 in New South Wales, Australia. Multivariable Cox regression modelled the impact of medical and surgical complications on the combined outcome of amputation or death two years after discharge. Results Open surgery was performed on 3004 patients (26.7%), and endovascular on 8263 (73.3%). Of the 10 971 patients discharged alive, 3747 (34.1%) experienced at least one complication, and 2113 (19.3%) had multiple complications. Older patients, those with high comorbidity scores, or those with chronic limb threatening ischaemia were at increased risk of multiple complications. After adjusting for procedure type, patients with multiple complications experienced more than three times the hazard ratio (HR) of amputation or death two years after the procedure than those without complications (adjusted HR 3.4, 95% confidence interval 3.1–3.7), and increasing complications progressively multiplied the risk. In particular, non-surgical complications such as stroke, acute renal failure, delirium, and cardiac events were associated with the highest rates of two year amputation or death. Conclusion Multiple complications after surgery for lower limb PAD carried a compounding risk of reduced long term amputation free survival. Patients experiencing at least one complication form a high risk group that requires increased attention to prevent the potential development of further complications.

Background The relations between diet, chronic inflammation, and musculoskeletal health are unclear, especially among older men. Objective This study aimed to determine associations of the Dietary Inflammatory Index (DII) with inflammatory biomarkers, musculoskeletal health, and falls risk in community-dwelling older men. Methods The cross-sectional analysis included 794 community-dwelling men, mean age 81.1 ± 4.5 y, who participated in the 5-y follow-up of the Concord Health and Aging in Men Project. Of these, 616 were seen again 3 y later for the longitudinal analysis. Energy-adjusted DII (E-DII) was calculated from a validated diet history questionnaire. Bone mineral density (BMD) was measured using DXA. Twenty-four inflammatory biomarkers were analyzed. Incident falls over 3 y were determined through telephone interviews every 4 mo. Multiple regression, linear mixed effects models, negative binomial regression, and mediation analysis were utilized in this study. Results A higher E-DII score (indicating a more proinflammatory diet) was associated with higher concentrations of IL-6 (β: 0.028 pg/mL; 95% CI: 0.003, 0.053), IL-7 (β: 0.020 pg/mL; 95% CI: 0.002, 0.037), and TNF-α (β: 0.027 pg/mL; 95% CI: 0.003, 0.051). A higher E-DII score was also associated with lower appendicular lean mass adjusted for BMI (ALMBMI) (β: -0.006 kg/m2; 95% CI: -0.010, -0.001). For every unit increase in E-DII (range: -4.91 to +3.66 units), incident falls rates increased by 13% (incidence rate ratio: 1.13; 95% CI: 1.05, 1.21) over 3 y. Mediation analysis showed that the association between E-DII and 3-y incident falls was influenced by the concentrations of IL-7 by 24%. There was no association between E-DII and BMD. Conclusions Consumption of a proinflammatory diet was associated with increased concentrations of IL-6, IL-7, and TNF-α; increased falls risk; and lower ALMBMI in community-dwelling older men. The association between incident falls and E-DII was partly mediated by concentrations of IL-7.

The aims of this study were to assess oral health-related quality of life (OHRQoL) in a cohort of older Australian men and explore the association between their general health conditions, socio-demographic factors and OHRQoL.The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of Australian men, initiated in 2005-2006 with an initial sample of 1705 men 70 years or over. Participants completed a self-administered health and socio-demographic questionnaire and attended an interview and clinical assessment at baseline and each of three follow-up assessments. Information on oral health and responses to the Oral Health Impact Profile (OHIP-14) were collected in the 4th follow-up in which 778 men completed the OHIP-14 questionnaire and 614 men had a dental assessment. The prevalence of oral health impact was defined as a response of fairly often or very often to one or more of the OHIP-14 questions. Mean OHIP-14 scores were calculated for the 14 questions and used as the dependent variable in the regression analyses. Zero-inflated Poisson regression was used to estimate prevalence rate ratios (PRR).Only 10% of men presented oral health impacts. In multivariate regression modelling, being born in Italy/Greece (PRR: 2.16, 95% CI: 1.93-2.42) or in other countries (PRR: 2.12, 95% CI: 1.89-2.38), having poor self-rated general health (PRR: 1.38, 95% CI: 1.24-1.53), having poor mental wellbeing (PRR: 1.14, 95% CI: 1.04-1.24), having ≥6 depressive symptoms (PRR: 1.18, 95% CI: 1.05-1.32), being a current smoker (PRR: 1.34, 95% CI: 1.06-1.70) and having more decayed tooth surfaces (PRR:1.01, 95% CI: 1.00-1.02) were associated with higher impact scores.Overall, older Australian men exhibit good oral health-related quality of life. The inter-relationship between perceptions of general health and well-being, health and oral health variables and social background supports policy objectives of closer integration of general health and oral health services for older Australian men.

Obtaining accurate estimates of the causal effects of socioeconomic position (SEP) on health is important for public health interventions. To do this, researchers must identify and adjust for all potential confounding variables, while avoiding inappropriate adjustment for mediator variables on a causal pathway between the exposure and outcome. Unfortunately, 'overadjustment bias' remains a common and under-recognized problem in social epidemiology. This paper offers an introduction on selecting appropriate variables for adjustment when examining effects of SEP on health, with a focus on overadjustment bias. We discuss the challenges of estimating different causal effects including overadjustment bias, provide guidance on overcoming them, and consider specific issues including the timing of variables across the life-course, mutual adjustment for socioeconomic indicators, and conducting systematic reviews. We recommend three key steps to select the most appropriate variables for adjustment. First, researchers should be clear about their research question and causal effect of interest. Second, using expert knowledge and theory, researchers should draw causal diagrams representing their assumptions about the interrelationships between their variables of interest. Third, based on their causal diagram(s) and causal effect(s) of interest, researchers should select the most appropriate set of variables, which maximizes adjustment for confounding while minimizing adjustment for mediators.

Objective There is an increasing demand for tertiary pain services, with long waiting times compounded by limited reach to regional and remote areas. Community-based pain programs are a feasible evidence-based model of care to improve access to multidisciplinary care. Australian primary health networks (PHNs) are well placed to commission pain programs to reduce the growing burden of chronic pain. The aim of this study was to support PHN decision-making by: (1) describing current PHN community-based pain programs; (2) assessing their alignment to key elements and implementation enablers of pain programs identified by an expert consensus process; and (3) describing PHN pain program adaptations during the COVID-19 pandemic. Methods PHN program managers of community-based pain programs (n = 9) were invited to participate in an online survey and follow-up email consultation about their pain program. Six PHN program managers (representing South Eastern NSW PHN, Nepean Blue Mountains PHN, North Western Melbourne PHN, Gold Coast PHN, Adelaide PHN and the WA Primary Health Alliance) participated in the study with three PHNs commissioning two different types of pain programs. Results PHN community-based pain programs are multidisciplinary programs underpinned by a biopsychosocial model of pain, and focus on self-management (e.g. exercise, psychological strategies) and pain education. Most PHN pain programs are group-based programs that target adults with chronic non-cancer pain, provide individual allied health referrals as required and are evaluated as part of the electronic Persistent Pain Outcomes Collaboration. Gaps include pain programs for Aboriginal and Torres Strait Islander people, and people from culturally and linguistically diverse backgrounds, with one notable exception of a PHN pain program for people from culturally and linguistically diverse and refugee backgrounds co-designed with consumers and relevant services. Programs targeting subacute pain to prevent progression to chronic pain are, with one exception, another gap area. PHN pain programs demonstrated a high level of alignment with expert-agreed key elements and implementation enablers. The COVID-19 pandemic precipitated the rapid adaptation of PHN pain programs using available methods for the delivery of digitally enabled care. Conclusions The findings provide a greater understanding for researchers and PHN decision-makers of the key features of PHN community-based pain programs, their alignment with expert-agreed key elements and implementation enablers, the target-population gaps, and the types of program adaptations during the COVID-19 pandemic. The findings also illustrate the potential for using digitally enabled delivery methods to increase accessibility to pain programs with further research warranted.

To evaluate the efficacy and safety of opioids for analgesic therapy for people with osteoarthritis.Systematic review and meta-analysis of randomised, placebo-controlled trials of opioid therapies for treating the pain of osteoarthritis. The primary outcome was medium term pain relief (six weeks to less than 12 months). Quality of evidence was assessed with GRADE criteria.MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews and Central Register of Controlled Trials, CINAHL, PsycINFO, AMED, and the WHO International Clinical Trials Registry; trials published to 31 October 2020.We extracted pain, disability, health-related quality of life, and adverse events data for 36 eligible trials (overall dose range: 10-210 oral morphine milligram equivalents [MME] per day). Continuous pain and disability outcomes were converted to common 0-100-point scales; changes of less than ten points were deemed to be very small effects. Differences in dichotomous outcomes were expressed as risk ratios. Data were pooled for meta-analysis in random effects models. The evidence from 19 trials (8965 participants; dose range, 10-126 MME/day) for very small medium term pain relief (mean difference [MD], -4.59 points; 95% CI, -7.17 to -2.02 points) was low quality, as was that from 16 trials (6882 participants; dose range, 10-126 MME/day) for a very small effect on disability (MD, -4.15 points; 95% CI, -6.94 to -1.35 points). Opioid dose was not statistically significantly associated with either degree of pain relief or incidence of adverse events in a meta-regression analysis. Evidence that opioid therapy increased the risk of adverse events (risk ratio, 1.43; 95% CI, 1.29-1.59) was of very low quality.Opioid medications may provide very small pain and disability benefits for people with osteoarthritis, but may also increase the risk of adverse events.CRD42019142813 (prospective).

The President of the International Association for the Study of Pain (IASP) established a Taskforce on Cannabis and Cannabinoid Analgesia, to systematically examine the evidence on (i) analgesic pharmacology of cannabinoids and preclinical evidence on their efficacy in animal models of injury-related or pathological persistent pain, (ii) the clinical efficacy of cannabis, cannabinoids and cannabis-based medicines (CBM) for pain, (iii) harms related to long-term use of cannabinoids, as well as (iv) societal issues and policy implications related to the use of these compounds for pain management. Here, we summarize key knowledge gaps identified in the Taskforce outputs and propose a research agenda for generating high-quality evidence on the topic. The systematic assessment of preclinical and clinical literature identified gaps in rigor of study design and reporting across the translational spectrum. We provide recommendations to improve the quality, rigor, transparency, and reproducibility of preclinical and clinical research on cannabis and cannabinoids for pain, as well as for the conduct of systematic reviews on the topic. Gaps related to comprehensive understanding of the endocannabinoid system and cannabinoid pharmacology, including pharmacokinetics and drug formulation aspects, are discussed. We outline key areas where high quality clinical trials with cannabinoids are needed. Important remaining questions about long-term and short-term safety of cannabis and cannabinoids are emphasized. Finally, regulatory, societal and policy challenges associated with medicinal and non-medicinal use of cannabis are highlighted, with recommendations for improving patient safety and reducing societal harms in the context of pain management.

IntroductionDespite the profound burden of disease, a strategic global response to optimise musculoskeletal (MSK) health and guide national-level health systems strengthening priorities remains absent. Auspiced by the Global Alliance for Musculoskeletal Health (G-MUSC), we aimed to empirically derive requisite priorities and components of a strategic response to guide global and national-level action on MSK health.MethodsDesign: mixed-methods, three-phase design.Phase 1: qualitative study with international key informants (KIs), including patient representatives and people with lived experience. KIs characterised the contemporary landscape for MSK health and priorities for a global strategic response.Phase 2: scoping review of national health policies to identify contemporary MSK policy trends and foci.Phase 3: informed by phases 1–2, was a global eDelphi where multisectoral panellists rated and iterated a framework of priorities and detailed components/actions.ResultsPhase 1: 31 KIs representing 25 organisations were sampled from 20 countries (40% low and middle income (LMIC)). Inductively derived themes were used to construct a logic model to underpin latter phases, consisting of five guiding principles, eight strategic priority areas and seven accelerators for action.Phase 2: of the 165 documents identified, 41 (24.8%) from 22 countries (88% high-income countries) and 2 regions met the inclusion criteria. Eight overarching policy themes, supported by 47 subthemes, were derived, aligning closely with the logic model.Phase 3: 674 panellists from 72 countries (46% LMICs) participated in round 1 and 439 (65%) in round 2 of the eDelphi. Fifty-nine components were retained with 10 (17%) identified as essential for health systems. 97.6% and 94.8% agreed or strongly agreed the framework was valuable and credible, respectively, for health systems strengthening.ConclusionAn empirically derived framework, co-designed and strongly supported by multisectoral stakeholders, can now be used as a blueprint for global and country-level responses to improve MSK health and prioritise system strengthening initiatives.

OBJECTIVES: Mediterranean dietary patterns may exert favorable effects on various health conditions. This study aimed to determine associations of adherence to Mediterranean diet with circulating cytokine levels, musculoskeletal health and incident falls in community-dwelling older men. METHODS: Seven hundred ninety-four (794) community-dwelling men with mean age 81.1 ± 4.5 years, who participated in the five-year follow-up of the Concord Health and Ageing in Men Project (CHAMP) were included in the cross-sectional analysis, and 616 attended follow-up three years later. Adherence to Mediterranean diet was assessed using MEDI-LITE (literature-derived Mediterranean diet) score which was derived using a validated diet history questionnaire. Twenty-four evaluable circulating cytokines were analyzed using Bio-Plex Pro Human Cytokine 27-plex Assay kit. Appendicular lean mass (ALM) and bone mineral density (BMD) were measured using dual-energy x-ray absorptiometry (DXA). Three-year changes in gait speed and hand grip strength were assessed by walking a 6-meter course and using a dynamometer respectively. Incident falls over three years were determined through telephone interviews every four months. RESULTS: A higher MEDI-LITE score, indicating greater adherence to Mediterranean diet, was associated with higher appendicular lean mass adjusted for body mass index (ALM(BMI)) (β: 0.004 kg/kg/m(2); 95% CI: 0.000, 0.008), and lower serum interleukin-7 (IL-7) (β: −0.017 pg/mL; 95% CI: −0.031, −0.003), and incident falls rates (IRR: 0.94; 95% CI: 0.89, 0.99). Higher consumption of monounsaturated fatty acids (IRR: 0.76; 95% CI: 0.59, 0.98) and monounsaturated fatty acids to saturated fatty acids ratio (IRR: 0.72; 95% CI: 0.57, 0.90) were associated with 24%, and 28% lower falls risk in older men respectively. MEDI-LITE scores were not associated with bone mineral density or physical function parameters. CONCLUSIONS: Adherence to a Mediterranean diet is associated with higher ALM(BMI), lower levels of serum IL-7, and fewer falls in community-dwelling older men. Monounsaturated and saturated fatty acids were the most important contributors to the association between Mediterranean diet and falls risk. FUNDING SOURCES: The CHAMP study is funded by the National Health and Medical Research Council of Australia, and the Ageing and Alzheimer's Institute.

ObjectiveLow levels of total cholesterol (TC) are associated with adverse outcomes in older populations. Whether this phenomenon is independent of statin use is unknown. We investigated the association between low TC levels and long-term major adverse cardiovascular events (MACE) in a prospective study of men aged ≥70 years without ischaemic heart disease (IHD) and whether this was influenced by statin use.MethodsThe CHAMP (Concord Health and Ageing in Men Project) cohort is a prospective cohort study of community-dwelling men aged ≥70 years. The relationship between TC and long-term MACE was analysed using Cox-regression modelling adjusted for comorbidities and stratified by statin use.ResultsThe study cohort comprised 1289 men (mean (±SD) age, 77.0±5.5 years; mean follow-up, 6.4±2.7 years). Decreasing TC level was associated with increased comorbidity burden, frailty and MACE (linear trend pConclusionLow TC is associated with increased risk of MACE in older men without IHD who are not taking statin therapy but not in those on statins.

Background The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of older Australian men. The aim of this paper is to describe the oral health behaviours and dental service use of CHAMP participants and explore associations between oral health behaviours with and general health status. Method Information collected related to socio‐demographics, general health, oral health service‐use and oral health behaviours. Key general health conditions were ascertained from the health questionnaire and included physical capacity and cognitive status. Results Fifty‐seven percent of the men reported visiting a dental provider at least once or more a year and 56.7% did so for a “dental check‐up”. Of those with some natural teeth, 59.3% claimed to brush their teeth at least twice or more a day. Most men (96%) used a standard fluoride toothpaste. Few participants used dental floss, tooth picks or mouth‐rinses to supplement oral hygiene. Cognitive status and self‐rated general health were associated with dental visiting patterns and toothbrushing behaviour. Conclusions Most older men in CHAMP perform favourable oral health behaviours. Smoking behaviour is associated with less favourable dental visiting patterns, and cognitive status with toothbrushing behaviour.

Background while both negative and positive impacts of caregiving on health have been reported, findings regarding caregiver’s mortality may be biased by the lack of consideration of changes in their health and caregiving status during follow-up. This study examines the impact of caregiving on the risk of death in older men, allowing for caregiving-transition by individuals and adjusting for changes over time in their health status. Methods data from 1639 men age ≥70 years old from the Concord Health and Ageing in Men Project (CHAMP) were collected between baseline (2005–07), 2-year and 5-year follow-up and linked to death records up to 30 September 2015. A time-varying Cox proportional hazards model was used to examine the risk of death from caregiving between 2005 and 2015, adjusting for baseline education, history of myocardial infarction, congestive heart failure, and risk factors which may change over time (age, income, self-rated overall health, number of morbidities, physical disability, depression and anxiety). Results the average follow-up was 7.39 years (SD = 2.95) with 495 deaths observed. There was no significant difference in all-cause mortality between caregivers and non-caregivers in the multivariable model (HR: 0.95, 95% CI: 0.67–1.32, P = 0.73). Conclusions this study addressed the dynamic caregiving role and covariates which has been rarely considered in the literature. While there is concern that when older people take on a caring role their health suffers, we found no difference in mortality between older male caregivers and non-caregivers when we accounted for transitions in their caregiving status.
