  Objective To assess the quality of care, effectiveness, and cost-effectiveness over 12 months after implementing a structured model of care for hip and knee osteoarthritis (OA) in primary healthcare as compared to usual care. Design In this pragmatic cluster-randomized, controlled trial with a stepped-wedge cohort design, we recruited 40 general practitioners (GPs), 37 physiotherapists (PTs), and 393 patients with symptomatic hip or knee OA from six municipalities (clusters) in Norway. The model included the delivery of a 3-hour patient education and 8–12 weeks individually tailored exercise programs, and interactive workshops for GPs and PTs. At 12 months, the patient-reported quality of care was assessed by the OsteoArthritis Quality Indicator questionnaire (16 items, pass rate 0–100%, 100%=best). Costs were obtained from patient-reported and national register data. Cost-effectiveness at the healthcare perspective was evaluated using incremental net monetary benefit (INMB). Results Of 393 patients, 109 were recruited during the control periods (control group) and 284 were recruited during interventions periods (intervention group). At 12 months the intervention group reported statistically significant higher quality of care compared to the control group (59% vs. 40%; mean difference: 17.6 (95% confidence interval [CI] 11.1, 24.0)). Cost-effectiveness analyses showed that the model of care resulted in quality-adjusted life-years gained and cost-savings compared to usual care with mean INMB €2020 (95% CI 611, 3492) over 12 months. Conclusions This study showed that implementing the model of care for OA in primary healthcare, improved quality of care and showed cost-effectiveness over 12 months compared to usual care.

  Objective: To evaluate the efficacy of strength exercise or aerobic exercise compared to usual care on knee-related quality of life (QoL) and knee function at 4 months and 1 year in individuals with knee osteoarthritis. Methods: A three-arm randomized controlled trial (RCT) compared 12 weeks of strength exercise or aerobic exercise (stationary cycling) to usual care supervised by physiotherapists in primary care. We recruited 168 participants aged 35–70 years with symptomatic knee osteoarthritis. The primary outcome was The Knee Injury and Osteoarthritis Outcome Score (KOOS) QoL at 1 year. Secondary outcomes were self-reported function, pain, and self-efficacy, muscle strength and maximal oxygen uptake (VO2max) at 4 months and 1 year. Results: There were no differences between strength exercise and usual care on KOOS QoL (6.5, 95% CI -0.9 to 14), or for aerobic exercise and usual care (5.0, 95% CI -2.7 to 12.8), at 1 year. The two exercise groups showed better quadriceps muscle strength, and VO2max at 4 months, compared to usual care. Conclusion: This trial found no statistically significant effects of two exercise programs compared to usual care on KOOS QoL at 1 year in individuals with symptomatic and radiographic knee osteoarthritis, but an underpowered sample size may explain lack of efficacy between the intervention groups and the usual care group.

  Objective: To assess construct validity (Rasch analyses) of the Measure of Activity Performance of the Hand (MAP-Hand) in people with carpometacarpal osteoarthritis (CMC1 OA), and to explore differences in activity performance between people with CMC1 OA and those with rheumatoid arthritis. Design: Cross-sectional study. Subjects: A total of 180 people with CMC1 OA referred for surgical consultation were recruited from rheumatology clinics in Norway, and 340 people with rheumatoid arthritis were recruited from outpatient rheumatology clinics in the UK. Methods: The MAP-Hand consists of 18 predefined items scored on a 4-point scale from 1 (no difficulty) to 4 (unable to do), from which a mean score is calculated. Construct validity was assessed using Rasch analyses. Differences between the 2 groups were assessed using an independent sample t-test at the group level and differential item functioning (condition as grouping variable) at the item level. Results: Some mis-targeting of data and clusters of dependency were found, but the MAP-Hand scores showed an overall fit to the model. No between-group difference in total mean MAP-Hand score was found, but there were significant differences between the 2 groups on item levels. Conclusion: The MAP-Hand showed satisfactory construct validity and could differentiate between people with CMC1 OA and those with rheumatoid arthritis on item levels.

  Background: To address the well-documented gap between hip and knee osteoarthritis (OA) treatment recommendations and current clinical practice, a structured model for integrated OA care was developed and evaluated in a stepped-wedge cluster-randomised controlled trial. The current study used secondary outcomes to evaluate clinically important response to treatment through the Outcome Measures in Rheumatology Clinical Trials clinical responder criteria (OMERACT-OARSI responder criteria) after 3 and 6 months between patients receiving the structured OA care model vs. usual care. Secondly, the study aimed to investigate if the proportion of responders in the intervention group was influenced by adherence to the exercise program inherent in the model. Methods: The study was conducted in primary healthcare in six Norwegian municipalities. General practitioners and physiotherapists received training in OA treatment recommendations and use of the structured model. The intervention group attended a physiotherapist-led OA education program and performed individually tailored exercises for 8–12 weeks. The control group received usual care. Patient-reported pain, function and global assessment of disease activity during the last week were evaluated using 11-point numeric rating scales (NRS 0–10). These scores were used to calculate the proportion of OMERACT-OARSI responders. Two-level mixed logistic regression models were fitted to investigate differences in responders between the intervention and control group. Results: Two hundred eighty-four intervention and 109 control group participants with hip and knee OA recruited from primary care in six Norwegian municipalities. In total 47% of the intervention and 35% of the control group participants were responders at 3 or 6 months combined; showing an uncertain between-group difference (ORadjusted 1.38 (95% CI 0.41, 4.67). In the intervention group, 184 participants completed the exercise programme (exercised ≥2 times/week for ≥8 weeks) and 55% of these were classified as responders. In contrast, 28% of the 86 non-completers were classified as responders. Conclusions: The difference in proportion of OMERACT-OARSI responders at 3 and 6 months between the intervention and control group was uncertain. In the intervention group, a larger proportion of responders were seen among the exercise completers compared to the non-completers.

  We present a concept including a set of tools for selfmanagement for patients suffering from axial spondyloarthritis (SpA). This concept involves patient-recorded outcome measures, both subjective assessment and clinical measurements, that are used to present recommendations. We report from experiences made while implementing a proof of this concept and analyse it from several perspectives. Our work resulted in proposing a self-management tool for the patient, improving the methodology for clinical measurements of rotation exercises, and proof the viability for using on-board sensors in smart phones. Further, since sensors collect data in a medical setting, we present ethical considerations.

  The objective of the study was to examine the hand-, knee- and hip osteoarthritis (OA) distribution, risk factor profiles and health-related quality of life (HRQoL) in a population-based OA cohort. Persons with self-reported OA responded to questionnaires and attended a clinical examination (N = 606). We analyzed cross-sectional associations to risk factor profiles and HRQoL dimensions (Short Form 36) in four mutually exclusive groups based on fulfillment of The American College of Rheumatology criteria: no OA (NOA), monoarticular upper extremity (hand) OA (MOAupper-ex.), monoarticular lower extremity (hip or knee) OA (MOAlower-ex.) and polyarticular OA (POA). Multivariate regression analyses and correspondence analysis were performed. The distribution of NOA, MOAupper-ex. MOAlower-ex. and POA was 21.1, 25.4, 22.4 and 31.0%, respectively. Compared to NOA, minor differences were found in risk factor profile in MOAupper-ex., whereas POA was significantly associated with sociodemographic, metabolic and mechanical features. The correspondence analysis identified different risk factor profiles between the four OA phenotypes, but the differences were not statistically significant (p = 0.13). Regarding HRQoL, neither OA groups were associated with poorer mental functioning. MOAlower-ex. and POA were associated with, among other things, poorer physical functioning (β = −6.2, 95% CI −11.2 to −1.2 and β = −12.5, 95% CI −17.4 to −7.9, respectively) and more pain (β = −5.4, 95% CI −10.4 to −0.3 and β = −10.5, 95% CI −15.3 to −5.8, respectively). In this cohort of persons with self-reported OA, POA was the most prevalent phenotype and was associated with an unfortunate risk factor profile and several diminished HRQoL dimensions. POA needs further attention in research and clinical care.

  We developed a concept including a set of tools for self-management for patients suffering from axial spondyloarthritis (SpA). This concept involves patient-recorded outcome measures, both subjective assessment and clinical measurements, that are used to present recommendations. We report from experiences made while implementing a proof of this concept. Besides giving the patient a self-management tool, our work also improved the methodology for clinical measurements.

  Objective To evaluate the state of quality of care for OA by summarizing studies that have assessed the care provided to patients. Methods A systematic review of community-based observational studies of actual clinical practice treating people with OA compared with quality indicators (QIs) was performed. Four databases were searched from January 2000 to November 2015. Two reviewers independently determined study eligibility, assessed risk of bias and extracted study data. The outcome was adherence to the QIs (pass rate). The overall pass rate (the total number of indicators passed divided by the total number of indicators for which the patients was eligible) was extracted from each study. When at least 50% of the studies had comparable individual QIs, the data were pooled with proportion meta-analyses. Results Fifteen studies comprising 16103 patients were included, and the median overall pass rate across studies was 41% (ranging from 22% to 65%). The pooled pass rates for individual QIs were: "Referral to orthopedic surgeon if no response to other therapy" 59.4% (95% Confidence Interval 47.5 - 70.3), "Paracetamol or acetaminophen first drug used" 46.0% (26.6 - 66.7), "Assessed for pain and/or function" 45.5% (33.9 - 57.6), "Referral or recommendation to exercise" 38.7% (28.9 - 49.5) "Offered education and self-management" 35.4% (27.8 - 44.0), and "Informed about potential risks if NSAIDs prescribed" 34.1% (24.7-44.9). Conclusion There is room for improvement in community-based OA care.

  Hand osteoarthritis (OA) is a prevalent joint disease that may lead to pain, stiffness and problems in performing hand-related activitiesof daily living. Currently, no cure for OA is known, and non-pharmacological modalities are recommended as first-line care. A positive effect of exercise in hip and knee OA has been documented, but the effect of exercise on hand OA remains uncertain. To assess the benefits and harms of exercise compared with other interventions, including placebo or no intervention, in people with hand OA. Main outcomes are hand pain and hand function. We searched six electronic databases up until September 2015. All randomised and controlled clinical trials comparing therapeutic exercise versus no exercise or comparing different exercise programmes. Two review authors independently selected trials, extracted data, assessed risk of bias and assessed the quality of the body of evidence using the GRADE approach. Outcomes consisted of both continuous (hand pain, physical function, finger joint stiffness and quality of life) and dichotomous outcomes (proportions of adverse events and withdrawals). We included seven studies in the review. Most studies were free from selection and reporting bias, but one study was available only as a congress abstract. It was not possible to blind participants to treatment allocation, and although most studies reported blinded outcome assessors, some outcomes (pain, function, stiffness and quality of life) were self-reported. The results may be vulnerable to performance and detection bias owing to unblinded participants and self-reported outcomes. Two studies with high drop-out rates may be vulnerable to attrition bias.We downgraded the overall quality of the body of evidence to low owing to potential detection bias (lack of blinding of participants on self-reported outcomes) and imprecision (studies were few, the number of participants was limited and Exercise for hand osteoarthritis (Review) 1 Copyright © 2017 The Cochrane Collaboration. Published by JohnWiley & Sons, Ltd. confidence intervals were wide for the outcomes pain, function and joint stiffness). For quality of life, adverse events and withdrawals due to adverse events, we further downgraded the overall quality of the body of evidence to very low because studies were very few and confidence intervals were very wide. Low-quality evidence fromfive trials (381 participants) indicated that exercise reduced hand pain (standardised mean difference (SMD) -0.27, 95% confidence interval (CI) -0.47 to -0.07) post intervention. The absolute reduction in pain for the exercise group, compared with the control group, was 5% (1% to 9%) on a 0 to 10 point scale. Pain was estimated to be 3.9 points on this scale (0 = no pain) in the control group, and exercise reduced pain by 0.5 points (95% CI 0.1 to 0.9; number needed to treat for an additional beneficial outcome (NNTB) 9). Four studies (369 participants) indicated that exercise improved hand function (SMD -0.28, 95% CI -0.58 to 0.02) post intervention. The absolute improvement in function noted in the exercise group, compared with the control group, was 6% (0.4% worsening to 13% improvement). Function was estimated at 14.5 points on a 0 to 36 point scale (0 = no physical disability) in the control group, and exercise improved function by 2.2 points (95% CI -0.2 to 4.6; NNTB 9). One study (113 participants) evaluated quality of life, and the effect of exercise on quality of life is currently uncertain (mean difference (MD) 0.30, 95% CI -3.72 to 4.32). The absolute improvement in quality of life for the exercise group, compared with the control group, was 0.3% (4% worsening to 4% improvement). Quality of life was 50.4 points on a 0 to 100 point scale (100 = maximum quality of life) in the control group, and the mean score in the exercise group was 0.3 points higher (3.5 points lower to 4.

  This research note is the Deliverable D3.1 of the MOSKUS project. We implemented a prototype of a self-management support system for patients with spondyloarthritis (SpA), a rheumatic disease. This prototype is based on the treat-to-target method and follows a concept that supports tools for self-management, clinical assessment, and better communication between patient and health personnel. The outcome of the implementation is twofold; first, a novel assessment methodology using sensors was developed and tested clinically; and second, a software system that can be used on smart phones currently implemented on the Android platform) was developed. This note describes the implementation aspects of the MOSKUS project.
