RESUMEN
BACKGROUND: Hand osteoarthritis is a disabling condition with few effective therapies. Hand osteoarthritis with synovitis is a common inflammatory phenotype associated with pain. We aimed to examine the efficacy and safety of methotrexate at 6 months in participants with hand osteoarthritis and synovitis. METHODS: In this multisite, parallel-group, double-blind, randomised, placebo-controlled trial, participants (aged 40-75 years) with hand osteoarthritis (Kellgren and Lawrence grade ≥2 in at least one joint) and MRI-detected synovitis of grade 1 or more were recruited from the community in Melbourne, Hobart, Adelaide, and Perth, Australia. Participants were randomly assigned (1:1) using block randomisation, stratified by study site and self-reported sex, to receive methotrexate 20 mg or identical placebo orally once weekly for 6 months. The primary outcome was pain reduction (measured with a 100 mm visual analogue scale; VAS) in the study hand at 6 months assessed in the intention-to-treat population. Safety outcomes were assessed in all randomly assigned participants. This trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12617000877381). FINDINGS: Between Nov 22, 2017, and Nov 8, 2021, of 202 participants who were assessed for eligibility, 97 (48%) were randomly assigned to receive methotrexate (n=50) or placebo (n=47). 68 (70%) of 97 participants were female and 29 (30%) were male. 42 (84%) of 50 participants in the methotrexate group and 40 (85%) of 47 in the placebo group provided primary outcome data. The mean change in VAS pain at 6 months was -15·2 mm (SD 24·0) in the methotrexate group and -7·7 mm (25·3) in the placebo group, with a mean between-group difference of -9·9 (95% CI -19·3 to -0·6; p=0·037) and an effect size (standardised mean difference) of 0·45 (0·03 to 0·87). Adverse events occurred in 31 (62%) of 50 participants in the methotrexate group and 28 (60%) of 47 participants in the placebo group. INTERPRETATION: Treatment of hand osteoarthritis and synovitis with 20 mg methotrexate for 6 months had a moderate but potentially clinically meaningful effect on reducing pain, providing proof of concept that methotrexate might have a role in the management of hand osteoarthritis with an inflammatory phenotype.

Rheumatological conditions are complex and impact many facets of daily life. Management of people with rheumatological conditions can be optimised through multidisciplinary care. However, the current access to nursing and allied health professionals in Australia is unknown. A cross-sectional study of nursing and allied health professionals in Australian public rheumatology departments for adult and paediatric services was conducted. The heads of Australian public rheumatology departments were invited to report the health professionals working within their departments, referral pathways, and barriers to greater multidisciplinary care. A total of 27/39 (69.2%) of the hospitals responded. The most common health professionals within departments were nurses (n = 23; 85.2%) and physiotherapists (n = 10; 37.0%), followed by pharmacists (n = 5; 18.5%), psychologists (n = 4; 14.8%), and occupational therapists (n = 4; 14.8%). No podiatrists were employed within departments. Referral pathways were most common for physiotherapy (n = 20; 74.1%), followed by occupational therapy (n = 15; 55.5%), podiatry (n = 13; 48.1%), and psychology (n = 6; 22%). The mean full-time equivalent of nursing and allied health professionals per 100,000 population in Australia was 0.29. Funding was identified as the most common barrier. In Australia, publicly funded multidisciplinary care from nurses and allied health professionals in rheumatology departments is approximately 1.5 days per week on average. This level of multidisciplinary care is unlikely to meet the needs of rheumatology patients. Research is needed to determine the minimum staffing requirements of nursing and allied health professionals to provide optimal care.

OBJECTIVE: To examine the association between medial meniscal extrusion and structural progression in adults with symptomatic knee osteoarthritis (OA). METHODS: This prospective cohort study examined 176 participants with symptomatic knee OA recruited into a randomised controlled trial. The participants underwent magnetic resonance imaging (MRI) of the study knee at baseline and approximately 2 years later. Meniscal extrusion, tibial cartilage volume, and tibiofemoral bone marrow lesions (BMLs) were measured from MRI using validated methods. RESULTS: Participants with medial meniscal extrusion ≥ 3 mm had a higher prevalence of lateral tibiofemoral BMLs at baseline (OR = 2.21, 95% CI 1.06-4.61, p = 0.035), and those with medial meniscal extrusion 2-3 mm had a higher likelihood of lateral BML worsening over 2 years (OR = 3.76, 95% CI 1.35-10.52, p = 0.011), compared with those with medial meniscal extrusion < 2 mm. Participants with stable medial meniscal extrusion had a lower likelihood of lateral BML worsening compared with those with regression of medial meniscal extrusion over 2 years (OR = 0.20, 95% CI 0.07-0.56, p = 0.002). There were no associations between medial meniscal extrusion and tibial cartilage volume or medial tibiofemoral BMLs. CONCLUSIONS: Our study showed associations between medial meniscal extrusion and baseline prevalence and worsening over 2 years of lateral tibiofemoral BMLs in people with symptomatic knee OA. Although the reasons for the lack of associations in the medial compartment are not clear, our results suggest a role of medial meniscal extrusion in predicting structural progression in lateral knee OA and that meniscal extrusion might be a potential target in the management of knee OA.
RESUMEN
Importance: Knee osteoarthritis is disabling, with few effective treatments. Preliminary evidence suggested that krill oil supplementation improved knee pain, but effects on knee osteoarthritis remain unclear. Objective: To evaluate efficacy of krill oil supplementation, compared with placebo, on knee pain in people with knee osteoarthritis who have significant knee pain and effusion-synovitis. Design, Setting, and Participants: Multicenter, randomized, double-blind, placebo-controlled clinical trial in 5 Australian cities. Participants with clinical knee osteoarthritis, significant knee pain, and effusion-synovitis on magnetic resonance imaging were enrolled from December 2016 to June 2019; final follow-up occurred on February 7, 2020. Interventions: Participants were randomized to 2 g/d of krill oil (n = 130) or matching placebo (n = 132) for 24 weeks. Main Outcomes and Measures: The primary outcome was change in knee pain as assessed by visual analog scale (range, 0-100; 0 indicating least pain; minimum clinically important improvement = 15) over 24 weeks. Results: Of 262 participants randomized (mean age, 61.6 [SD, 9.6] years; 53% women), 222 (85%) completed the trial. Krill oil did not improve knee pain compared with placebo (mean change in VAS score, -19.9 [krill oil] vs -20.2 [placebo]; between-group mean difference, -0.3; 95% CI, -6.9 to 6.4) over 24 weeks. One or more adverse events was reported by 51% in the krill oil group (67/130) and by 54% in the placebo group (71/132). The most common adverse events were musculoskeletal and connective tissue disorders, which occurred 32 times in the krill oil group and 42 times in the placebo group, including knee pain (n = 10 with krill oil; n = 9 with placebo), lower extremity pain (n = 1 with krill oil; n = 5 with placebo), and hip pain (n = 3 with krill oil; n = 2 with placebo). Conclusions and Relevance: Among people with knee osteoarthritis who have significant knee pain and effusion-synovitis on magnetic resonance imaging, 2 g/d of daily krill oil supplementation did not improve knee pain over 24 weeks compared with placebo. These findings do not support krill oil for treating knee pain in this population.

OBJECTIVES: To determine long-term (20 year) survival in RA patients enrolled in the Australian Rheumatology Association Database (ARAD). METHODS: ARAD patients with RA and data linkage consent who were diagnosed from 1995 onwards were included. Death data were obtained through linkage to the Australian National Death Index. Results were compared with age-, gender- and calendar year-matched Australian population mortality rates. Analysis included both the standardized mortality ratio (SMR) and relative survival models. Restricted mean survival time (RMST) at 20 years was calculated as a measure of life lost. Cause-specific SMRs (CS-SMRs) were estimated for International Classification of Diseases, Tenth Revision cause of death classifications. RESULTS: A total of 1895 RA patients were included; 74% were female, baseline median age 50 years (interquartile range 41-58), with 204 deaths. There was no increase in mortality over the first 10 years of follow up, but at 20 years the SMR was 1.49 (95% CI 1.30, 1.71) and the relative survival was 94% (95% CI 91, 97). The difference between observed (18.41 years) and expected (18.68 years) RMST was 4 months. Respiratory conditions were an important underlying cause of death in RA, primarily attributable to pneumonia [CS-SMR 5.2 (95% CI 2.3, 10.3)] and interstitial lung disease [CS-SMR 7.6 (95% CI 3.0, 14.7)], however, coronary heart disease [CS-SMR 0.82 (95% CI 0.42, 1.4)] and neoplasms [CS-SMR 1.2 (95% CI 0.89, 1.5)] were not. CONCLUSION: Mortality risk in this RA cohort accrues over time and is moderately increased at 20 years of follow-up. Respiratory diseases may have supplanted cardiovascular diseases as a major contributor to this mortality gap.

OBJECTIVE: To describe the frequency of progressive pulmonary fibrosis (PPF) in an incident cohort of systemic sclerosis (SSc) related interstitial lung disease (ILD) and its impact on survival. METHODS: Incident ILD was defined as the new development of characteristic fibrotic changes on chest HRCT scan. PPF was defined as per the 2022 American Thoracic Society. Determinants of PPF were identified using generalised estimating equations. Impact on survival was analysed using accelerated failure time regression modelling. RESULTS: Of our incident SSc-ILD cases, 38.8% (n = 180) experienced PPF within a 12-month period after ILD diagnosis. Determinants of PPF included older age (OR 1.02, 95%CI 1.00-1.03, p= 0.011), dcSSc (OR 1.54, 95% CI 1.06-2.25, p= 0.024) and SSc specific antibodies (anticentomere antibody OR 0.51, 95%CI 0.29-0.91, p= 0.021 and anti-Scl-70 antibody OR 1.46, 95%CI 1.01-2.09, p= 0.043). Raised CRP was numerically associated with PPF but did not reach statistical significance (OR 1.29, 95%CI 0.99-1.68, p= 0.064) nor did GORD or dysphagia (OR 1.18, 95%CI 0.57-2.42, p= 0.658 and OR 1.17, 95%CI 0.57-2.40, p= 0.664 respectively). The presence of PPF significantly impacted survival in SSc-ILD (hazard ratio 2.66, 95%CI 1.59-4.41, p< 0.001). CONCLUSIONS: PPF occurred in a third of our incident SSc-ILD cohort; however, its occurrence was significantly associated with mortality indicating an at-risk group who may be suitable for earlier introduction of immunosuppressive and/or antifibrotic therapy.
RESUMEN
OBJECTIVES: To determine COVID-19 vaccine hesitancy rates in inflammatory arthritis patients and identify factors associated with changing vaccine hesitancy over time. METHODS: This investigation was a prospective cohort study of inflammatory arthritis patients from community and public hospital outpatient rheumatology clinics enrolled in the Australian Rheumatology Association Database (ARAD). Two surveys were conducted, one immediately prior to (pre-pandemic) and another approximately 1 year after the start of the pandemic (follow-up). Coronavirus disease 2019 (COVID-19) vaccine hesitancy was measured at follow-up, and general vaccine hesitancy was inferred pre-pandemic; these were used to identify factors associated with fixed and changing vaccine beliefs, including sources of information and broader beliefs about medication. RESULTS: Of the 594 participants who completed both surveys, 74 (12%) were COVID-19 vaccine hesitant. This was associated with pre-pandemic beliefs about medications being harmful (P < 0.001) and overused (P = 0.002), with stronger beliefs resulting in vaccine hesitancy persistent over two time points (P = 0.008, P = 0.005). For those not vaccine hesitant pre-pandemic, the development of COVID-19 vaccine hesitancy was associated with a lower likelihood of seeking out vaccine information from health-care professionals (P < 0.001). COVID-19 vaccine hesitancy was not associated with new influenza vaccine hesitancy (P = 0.138). CONCLUSION: In this study of vaccine beliefs before and during the COVID-19 pandemic, factors associated with COVID-19 vaccine hesitancy in inflammatory arthritis patients varied, depending on vaccine attitudes immediately prior to the start of the pandemic. Fixed beliefs reflected broader views about medications, while fluid beliefs were highly influenced by whether they sought out information from health-care professionals, including rheumatologists.

OBJECTIVE: There is increasing evidence for the involvement of vascular disease in the pathogenesis of knee OA. Popliteal artery wall thickness can be used as a surrogate marker of atherosclerosis. We examined the association between popliteal artery wall thickness and knee cartilage volume in individuals with symptomatic knee OA. METHODS: This prospective cohort study analysed 176 participants from a randomized placebo-controlled trial examining the effect of atorvastatin on structural progression in knee OA. The participants underwent MRI of the study knee at baseline and 2-year follow-up. Popliteal artery wall thickness and tibial cartilage volume were measured from MRI using validated methods. The top quartile of the rate of tibial cartilage volume loss was defined as rapid progression. RESULTS: At baseline, every 10% increase in popliteal artery wall thickness was associated with 120.8 mm3 (95% CI 5.4, 236.2, P = 0.04) lower of medial tibial cartilage volume and 151.9 mm3 (95% CI 12.1, 291.7, P = 0.03) lower of lateral tibial cartilage volume. Longitudinally, for every 10% increase in popliteal artery wall thickness, the annual rate of medial tibial cartilage volume loss was increased by 1.14% (95% CI 0.09%, 2.20%, P = 0.03), and there was a 2.28-fold (95% CI 1.07, 4.83, P = 0.03) risk of rapid progression of medial tibial cartilage loss, adjusted for age, sex, BMI, tibial bone area, smoking, vigorous physical activity, and intervention group allocation. CONCLUSION: The findings support a role for vascular pathology in the progression of knee OA. Targeting atherosclerosis has the potential to improve outcomes in knee OA.

BACKGROUND: Low back pain (LBP) is the most common musculoskeletal disorder globally. Providing region- and national-specific information on the burden of low back pain is critical for local healthcare policy makers. The present study aimed to report, compare, and contextualize the prevalence, incidence and years lived with disability (YLDs) of low back pain in the Middle East and North Africa (MENA) region by age, sex and sociodemographic index (SDI), from 1990 to 2019. METHODS: Publicly available data were obtained from the Global Burden of Disease (GBD) study 2019. The burden of LBP was reported for the 21 countries located in the MENA region, from 1990 to 2019. All estimates were reported as counts and age-standardised rates per 100,000 population, together with their corresponding 95% uncertainty intervals (UIs). RESULTS: In 2019, the age-standardised point prevalence and incidence rate per 100,000 in MENA were 7668.2 (95% UI 6798.0 to 8363.3) and 3215.9 (95%CI 2838.8 to 3638.3), which were 5.8% (4.3 to 7.4) and 4.4% (3.4 to 5.5) lower than in 1990, respectively. Furthermore, the regional age-standardised YLD rate in 2019 was 862.0 (605.5 to 1153.3) per 100,000, which was 6.0% (4.2 to 7.7) lower than in 1990. In 2019, Turkey [953.6 (671.3 to 1283.5)] and Lebanon [727.2 (511.5 to 966.0)] had the highest and lowest age-standardised YLD rates, respectively. There was no country in the MENA region that showed increases in the age-standardised prevalence, incidence or YLD rates of LBP over the measurement period. Furthermore, in 2019 the number of prevalent cases were highest in the 35-39 age group, with males having a higher number of cases in all age groups. In addition, the age-standardised YLD rates for males in the MENA region were higher than the global estimates in almost all age groups, in both 1990 and 2019. Furthermore, the burden of LBP was not associated with the level of socio-economic development during the measurement period. CONCLUSION: The burden attributable to LBP in the MENA region decreased slightly from 1990 to 2019. Furthermore, the burden among males was higher than the global average. Consequently, more integrated healthcare interventions are needed to more effectively alleviate the burden of low back pain in this region.

OBJECTIVES: We compared survival and causes of death in Western Australian (WA) ANCA-associated vasculitis (AAV) and PAN patients with controls and the WA population. METHODS: In this data linkage study, we identified patients with incident AAV/PAN and age, sex and temporally matched controls 1980-2014 from the WA Rheumatic Disease Epidemiological Registry. Survival analyses and time-varying analyses were performed. RESULTS: Six hundred and fourteen patients with incident AAV/PAN were compared with 6672 controls; 229 AAV/PAN patients died over 5277 person-years of follow-up and 1009 controls died over 73835 person-years. Survival was reduced in patients with AAV/PAN compared with matched controls [hazard ratio (HR) 3.5 (95% CI: 3.1, 4.1)], and matched WA population rates [standardized mortality ratio 3.3 (95% CI: 2.9, 3.8)]. Greatest excess mortality in AAV/PAN patients was observed in the first year after diagnosis and remained higher than controls throughout follow-up. Greater excess mortality was observed in patients >60 years at diagnosis. In cause-specific analyses, mortality HR for vasculitis, infection and non-infective respiratory disease were greatest early after diagnosis and remained persistently elevated. The HRs for malignancy and cerebrovascular disease related deaths increased during follow-up, and were constant for ischaemic heart disease related deaths. CONCLUSION: Mortality was increased in AAV/PAN patients compared with controls, with patients older at diagnosis at greater risk. These findings provide mortality risk for AAV/PAN in an Australian population, highlighting key contributors to mortality at different time periods over follow-up and potential areas of focus for reducing mortality.

BACKGROUND: Outpatient clinics were shifted rapidly to telehealth in Australia during the Coronavirus disease 19 (COVID-19) pandemic, drastically altering patient care and experience. AIMS: To investigate patient satisfaction and acceptability of telehealth consultations during the COVID-19 pandemic. METHODS: Prospective observation study conducted in two hospital rheumatology outpatient departments (OPD) undertaking telehealth consultations during COVID-19. A modified version of a validated telehealth evaluation survey was posted to all patients attending the telehealth OPD rheumatology clinics, including balanced 5-point Likert scales and free-text responses. Cluster analysis was applied to the Likert-scale questions, alongside thematic analysis of free-text responses. RESULTS: There were 128 respondents (29% response rate), of which 69.5% were women and the majority (87.5%) was aged 50 years or older. All telehealth consultations were conducted by telephone. Nearly one-fifth of patients indicated consistent dissatisfaction with telehealth across the range of questions. These patients were older, reported lower educational qualifications and lower health literacy scores and lacked access to the Internet. While many patients found this mode of consultation to be convenient, patients expressed concerns regarding absence of physical examination. A recurrent theme was a desire for a mixed-model clinic in the future, with flexibility of having both telehealth and face-to-face consultations. CONCLUSIONS: This study offers unique insights into patients' experiences with telehealth, which until the current global pandemic, has been an uncommon mode of consultation delivery in urban areas. This study suggests when defining the place of telehealth in future healthcare delivery, patient perspective and careful patient selection will be key. Disease progression, language and cognitive ability, health literacy, technology access and patient and clinician preference are important considerations when deciding how effectively to embed and integrate telehealth into consultations.

BACKGROUND: Scleroderma renal crisis (SRC) is a rare but feared complication with high morbidity and mortality. Its aetiopathogenesis is unclear. AIM: To investigate epidemiological, serologic and clinical features of all patients with SRC listed on the population-based South Australian Scleroderma Register and to examine possible factors in aetiopathogenesis. METHOD: A case note review was performed on all SRC patients with relevant data extracted to determine incidence, clinical phenotype, presence of autoantibodies and survival. Possible precipitating and aetiopathogenic factors were also examined. Data from the South Australian Scleroderma Register and Australia Bureau of Statistics was sourced for comparative purposes. RESULTS: Over the 34-year period (1985-2018), 30 patients (21 females, 9 males) presented with SRC giving a South Australian mean annual incidence of 0.58/million/year (95% CI 0.39-0.89). Twenty-eight of these patients had diffuse cutaneous scleroderma and two with limited cutaneous scleroderma. The mean age at first symptom of scleroderma was 51.2 ± 15.9 (mean ± SD) years with SRC occurring 4.6 years later (median = 3.0 years, range 0.1-20 years). Possible precipitating factors for SRC included high dose steroids in five patients. Twelve patients were anti- RNA polymerase3 (RNAPol3) positive and two were anti-topoisomerase 1 (Topo1) positive. Renal outcome was poor with 13 patients requiring renal replacement therapy and two proceeding to renal transplantation. The mean age at death was 61.2 ± 11.6 years with SRC patient survival being significantly shorter than patients with diffuse scleroderma without renal involvement (P = 0.002). There was no significant difference in survival between the 1985-2002 and the 2003-2018 SRC cohorts (P = 0.2). Nailfold capillaroscopy performed in 10 patients revealed extensive microvascular damage with prominent capillary drop out. CONCLUSION: SRC is a rare occurrence with an incidence of 0.58/million/year in South Australia. This frequency has not changed over time. It continues to have a severe adverse outcome with frequent requirement for renal replacement therapy and poor survival. Nailfold capillaroscopy revealed evidence of extensive capillary damage. No improvement in survival was observed over the 34-year study period.

BACKGROUND: Hand osteoarthritis is a common and disabling problem without effective therapies. Accumulating evidence suggests the role of local inflammation in causing pain and structural progression in hand osteoarthritis, and hand osteoarthritis with synovitis is a commonly encountered clinical phenotype. Methotrexate is a well-established, low-cost, and effective treatment for inflammatory arthritis with a well-described safety profile. The aim of this multicentre, randomised, double-blind, placebo-controlled trial is to determine whether methotrexate reduces pain over 6 months in patients with hand osteoarthritis and synovitis. METHODS: Ninety-six participants with hand osteoarthritis and synovitis will be recruited through the Osteoarthritis Clinical Trial Network (Melbourne, Hobart, Adelaide, and Perth), and randomly allocated in a 1:1 ratio to receive either methotrexate 20 mg or identical placebo once weekly for 6 months. The primary outcome is pain reduction (assessed by 100 mm visual analogue scale) at 6 months. The secondary outcomes include changes in physical function and quality of life assessed using Functional Index for Hand Osteoarthritis, Australian Canadian Osteoarthritis Hand Index, Health Assessment Questionnaire, Michigan Hand Outcomes Questionnaire, Short-Form-36, tender and swollen joint count, and grip strength, and structural progression assessed using progression of synovitis and bone marrow lesions from magnetic resonance imaging and radiographic progression at 6 months. Adverse events will be recorded. The primary analysis will be by intention to treat, including all participants in their randomised groups. DISCUSSION: This study will provide high-quality evidence to address whether methotrexate has an effect on reducing pain over 6 months in patients with hand osteoarthritis and synovitis, with major clinical and public health importance. While a positive trial will inform international clinical practice guidelines for the management of hand osteoarthritis, a negative trial would be highly topical and change current trends in clinical practice.

BACKGROUND/OBJECTIVE: The objective of this cohort study was to understand the positive and negative effects of glucocorticoids (GCs) in patients with systemic lupus erythematosus and myositis from the patients' perspective with the aim of developing a patient-reported outcome measure. METHODS: Included patients were asked to participate in 1 of 5 nominal groups where demographic information and a quality-of-life questionnaire were collected. Patients were asked 2 open-ended questions on (1) benefits and (2) harms related to GC use. We used the Nominal Group Technique, a highly structured consensus method in which responses are generated, shared, and ranked. Descriptive statistics were used to summarize the results. Nominal group sessions took place from April to May 2019. RESULTS: Of 206 patients who were approached, 21 patients participated, 17 with systemic lupus erythematosus and 4 with myositis, predominantly women with more than 10 years of steroid use. The domains ranked highest for GC benefits were disease control (55 votes), fast onset of action (30 votes), increased energy (10 votes), and pain relief (10 votes). The highest-ranked negative effects were bone loss (38 votes) and weight gain (16 votes); psychological effects and damaged internal organs each received 12 votes. CONCLUSIONS: The top-ranked GC effects-both benefits and harms-among patients with systemic rheumatic disease are consistent with the top domains associated with GC use reported with other inflammatory diseases. This study informs the development of a comprehensive patient-reported outcome measure that can be used across inflammatory diseases.

OBJECTIVE: To quantify the burden of interstitial lung disease (ILD) in SSc. METHODS: Clinical data for SSc patients enrolled in the Australian Scleroderma Cohort Study were linked with healthcare databases for the period 2008-2015. ILD was defined by characteristic fibrotic changes on high-resolution CT (HRCT) lung, while severity was defined by the extent lung involvement on HRCT (mild <10%, moderate 10-30%, severe >30%). Determinants of healthcare cost were estimated using logistic regression. RESULTS: SSc-ILD patients utilized more healthcare resources, including hospitalization, emergency department presentation and ambulatory care services, than those without ILD with a total cost per patient of AUD$48 368 (26 230-93 615) vs AUD$33 657 (15 144-66 905), P<0.001) between 2008-2015. Healthcare utilization was associated with an annual median (25th-75th) excess cost per SSc-ILD patient compared with those without ILD of AUD$1192 (807-1212), P<0.001. Increasing ILD severity was associated with significantly more healthcare utilization and costs with an annual excess cost per patient with severe ILD compared with mild ILD of AUD$2321 (645-1846), P<0.001. ILD severity and the presence of coexistent PAH were the main determinants of overall healthcare cost above median for this SSc-ILD cohort (OR 5.1, P<0.001, and OR 2.6, P=0.01, respectively). Furthermore, SSc-ILD patients reported worse physical HRQoL compared with those without ILD [34.3 (10.5) vs 39.1 (10.8), P<0.001], with a progressive decline with increasing ILD severity (P=0.002). CONCLUSION: SSc-ILD places a large burden on the healthcare system and the patient through poor HRQoL in addition to incremental healthcare resource utilization and associated direct cost.

BACKGROUND: An understanding of the average range of movement of the shoulder that is normally achievable is an important part of treatment for shoulder disorders. The average range of active shoulder flexion, abduction and external rotation was measured in a population cohort aged 20 years and over without shoulder pain and/or stiffness in order to provide normative shoulder range data. METHODS: Cross-sectional analysis using participants in a community-based longitudinal cohort study. There have been three stages of data collection - Stage 1 (1999-2003), Stage 2 (2004-2006) and Stage 3 (2008-2010). Each stage has consisted a of broad ranging computer assisted telephone interview, a self-complete questionnaire and a clinic assessment. Participants in this study are those who undertook assessments in Stage 2. The main outcome measures were active shoulder range of movement (flexion, abduction and external rotation) measured as part of the clinic assessment using a Plurimeter V inclinometer. Mean values were determined and analyses to examine differences between groups (sex and age) were undertaken using non-parametric tests. RESULTS: There were 2404 participants (51.5% male), mean age 45.8 years (SD 17.3, range 20-91). The average range of active right shoulder flexion was 161.5° for males and 158.5° for females, and active right shoulder abduction was 151.5° and 149.7° for males and females respectively. Shoulder range of movement declined with age, with mean right active shoulder flexion decreasing by 43° in males and 40.6° in females and right active shoulder abduction by 39.5° and 36.9° respectively. External rotation range also declined, particularly among females. CONCLUSION: To our knowledge this is the largest community-based study providing normative data for active shoulder range of movement. This information can be used to set realistic goals for both clinical practice and clinical trials.

BACKGROUND: To quantify the financial cost of pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc). METHODS: Healthcare use was captured through data linkage, wherein clinical data for SSc patients enrolled in the Australian Scleroderma Cohort Study were linked with hospital, emergency department (ED) and ambulatory care databases (MBS) for the period 2008-2015. PAH was diagnosed on right heart catheter according to international criteria. Determinants of healthcare cost were estimated using logistic regression. RESULTS: Total median (25th-75th) healthcare cost per patient (including hospital, ED and MBS cost but excluding medication cost) for our cohort during 2008-2015 was AUD$37,685 (18,144-78,811) with an annual per patient healthcare cost of AUD$7506 (5273-10,654). Total healthcare cost was higher for SSc-PAH patients compared with those without PAH with a total cost per patient of AUD$70,034 (37,222-110,814) vs AUD$34,325 (16,093 - 69,957), p < 0.001 respectively with an annual excess healthcare cost per PAH patient of AUD$2463 (1973-1885), p < 0.001. The cost of SSc-PAH occurs early post PAH diagnosis with 89.4% utilizing a healthcare service within the first 12 months post PAH diagnosis with an associated cost per patient of AUD$4125 (0-15,666). PAH severity was the main significant determinant of increased healthcare cost (OR 2.5, p = 0.03) in our PAH cohort. CONCLUSIONS: Despite SSc-PAH being a low prevalence disease, it is associated with significant healthcare resource utilization and associated economic burden, predominantly driven by the severity of PAH.

OBJECTIVES: The aim was to assess whether the Knee Society Score, Oxford Knee Score (OKS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) were comparable in asymptomatic, healthy, individuals of different age, gender and ethnicity, across two remote continents. The purpose of this study was to establish normal population values for these scores using an electronic data collection system. HYPOTHESIS: There is no difference in clinical knee scores in an asymptomatic population when comparing age, gender and ethnicity, across two remote continents. METHODS: 312 Australian and 314 Canadian citizens, aged 18-94 years, with no active knee pain, injury or pathology in the ipsilateral knee corresponding to their dominant arm, were evaluated. A knee examination was performed and participants completed an electronically administered questionnaire covering the subjective components of the knee scores. The cohorts were age- and gender-matched. Chi-square tests, Fisher's exact test and Poisson regression models were used where appropriate, to investigate the association between knee scores, age, gender, ethnicity and nationality. RESULTS: There was a significant inverse relationship between age and all assessment tools. OKS recorded a significant difference between gender with females scoring on average 1% lower score. There was no significant difference between international cohorts when comparing all assessment tools. CONCLUSIONS: An electronic, multi-centre data collection system can be effectively utilized to assess remote international cohorts. Differences in gender, age, ethnicity and nationality should be taken into consideration when using knee scores to compare to pathological patient scores. This study has established an electronic, normal control group for future studies using the Knee society, Oxford, and KOOS knee scores. LEVEL OF EVIDENCE: Diagnostic Level II.

BACKGROUND: Guidelines suggest treatment in rheumatoid arthritis (RA) to target remission, in close consultation with the patient. Our recent qualitative study of the patients' perspective on remission in RA identified 26 domains. The current study aimed to identify a short list of the most important aspects to inform future research. METHODS: Patients with RA from the Netherlands, the UK, Austria, Denmark, France and the USA completed a survey that contained all domains identified in our qualitative study. They rated domains for importance ('not important', 'important' or 'essential' to characterise a period of remission) and if important or essential, whether this domain needs to be 'less', 'almost gone' or 'gone' to reflect remission. Respondents were also asked to determine their personal top 3 most important/essential domains. Frequency of specific domains in the top 3 was calculated, and domains were sorted on the percentage of patients that evaluated a particular domain as 'essential'. RESULTS: Of 274 respondents, 75% were female, mean (SD) age 57(13) years, disease duration 12(9) years. The top 3 were as follows: pain (67%), fatigue (33%) and independence (19%); domains most frequently rated as 'essential' were as follows: pain (60%), being mobile (52%), physical function (51%), being independent (47%) and fatigue (41%). Pain needed to be less (13%), almost gone (42%) or gone (45%) to reflect remission. Similar patterns were seen for fatigue, independence, mobility and physical functioning. CONCLUSION: Patients identified pain, fatigue and independence as the most important domains of RA disease activity that need to be improved to reflect remission.

BACKGROUND: Chronic diseases are highly prevalent and cluster in individuals (multimorbidity). This study investigated the association between multimorbidity and Health-Related Quality of Life (HRQoL), assessing the combination of chronic diseases highly correlated with this outcome. METHODS: We conducted a household survey in 2015 in a random sample of 2912 South Australian adults (48.9 ± 18.1 years; 50.9% females), obtaining information on sociodemographics, lifestyle, and 17 chronic conditions clustered in four different groups (metabolic, cardiovascular, gastrointestinal, and musculoskeletal). Information on physical (PCS) and mental components scores (MCS) of HRQoL were assessed using the SF-12 questionnaire. Multivariable linear regression models considering individual diseases (mutually adjusted) and clusters within- and between-groups were used to test the associations. RESULTS: Only 41% of the sample was negative for all the investigated diseases. The most prevalent conditions were osteoarthritis, obesity and hypertension, which affected one in every four individuals. PCS was markedly lower among those reporting stroke, heart failure, and osteoarthritis, but they were not associated with MCS. Direct-trend relationships were observed between the number of chronic conditions (clusters within- and between-groups) and PCS, but not with MCS. The strongest association with PCS was for musculoskeletal conditions (difference between those affected by 2+ conditions and those free of these conditions -6.7 95%CI -8.5;-5.4), and lower PCS were observed in any combination of clusters between-group including musculoskeletal diseases. CONCLUSION: In the context of multimorbidity, musculoskeletal diseases are a key determinant group of PCS, amplifying the association of other chronic conditions on physical but not on mental health.
