2023 EULAR classification criteria for hand osteoarthritis.

OBJECTIVES: The objective of this study is to develop classification criteria for overall hand osteoarthritis (OA), interphalangeal OA and thumb base OA based on self-reported data and radiographic features. METHODS: The classification criteria sets were developed in three phases. In phase 1, we identified criteria that discriminated hand OA from controls. In phase 2, we used a consensus-based decision analysis approach to derive a clinician-based evaluation of the relative importance of the criteria. In phase 3, we refined the scoring system, determined the cut-offs for disease classification and compared the sensitivity and specificity of the European Alliance of Associations for Rheumatology (EULAR) criteria with the 1990 American College of Rheumatology (ACR) criteria. RESULTS: In persons with hand symptoms and no other disease (including psoriasis) or acute injury that can explain the hand symptoms (mandatory criteria), hand OA can be classified based on age, duration of morning stiffness, number of joints with osteophytes and joint space narrowing, and concordance between symptoms and radiographic findings. Using a sum of scores based on each diagnostic element, overall hand OA can be classified if a person achieves 9 or more points on a 0-15 scale. The cut-off for interphalangeal OA and thumb base OA is 8 points. While the EULAR criteria demonstrated better sensitivity than the ACR criteria in the phase 1 data set, the performance of the two criteria sets was similar in two external cohorts. CONCLUSIONS: International experts developed the EULAR criteria to classify overall hand OA, interphalangeal OA and thumb base OA in clinical studies using a rigorous methodology.

Mechanisms of action of therapeutic exercise for knee and hip OA remain a black box phenomenon: an individual patient data mediation study with the OA Trial Bank.

OBJECTIVES: To evaluate mediating factors for the effect of therapeutic exercise on pain and physical function in people with knee/hip osteoarthritis (OA). METHODS: For Subgrouping and TargetEd Exercise pRogrammes for knee and hip OsteoArthritis (STEER OA), individual participant data (IPD) were sought from all published randomised controlled trials (RCTs) comparing therapeutic exercise to non-exercise controls in people with knee/hip OA. Using the Counterfactual framework, the effect of the exercise intervention and the percentage mediated through each potential mediator (muscle strength, proprioception and range of motion (ROM)) for knee OA and muscle strength for hip OA were determined. RESULTS: Data from 12 of 31 RCTs of STEER OA (1407 participants) were available. Within the IPD data sets, there were generally statistically significant effects from therapeutic exercise for pain and physical function in comparison to non-exercise controls. Of all potential mediators, only the change in knee extension strength was statistically and significantly associated with the change in pain in knee OA (ß -0.03 (95% CI -0.05 to -0.01), 2.3% mediated) and with physical function in knee OA (ß -0.02 (95% CI -0.04 to -0.00), 2.0% mediated) and hip OA (ß -0.03 (95% CI -0.07 to -0.00), no mediation). CONCLUSIONS: This first IPD mediation analysis of this scale revealed that in people with knee OA, knee extension strength only mediated ±2% of the effect of therapeutic exercise on pain and physical function. ROM and proprioception did not mediate changes in outcomes, nor did knee extension strength in people with hip OA. As 98% of the effectiveness of therapeutic exercise compared with non-exercise controls remains unexplained, more needs to be done to understand the underlying mechanisms of actions.

Development of radiographic classification criteria for hand osteoarthritis: a methodological report (Phase 2).

OBJECTIVES: In Phase 1 of developing new hand osteoarthritis (OA) classification criteria, features associated with hand OA were identified in a population with hand complaints. Radiographic findings could better discriminate patients with hand OA and controls than clinical examination findings. The objective of Phase 2 was to achieve consensus on the features and their weights to be included in three radiographic criteria sets of overall hand OA, interphalangeal OA and thumb base OA. METHODS: Multidisciplinary, international expert panels were convened. Patient vignettes were used to identify important features consistent with hand OA. A consensus-based decision analysis approach implemented using 1000minds software was applied to identify the most important features and their relative importance influencing the likelihood of symptoms being due to hand OA. Analyses were repeated for interphalangeal and thumb base OA. The reliability and validity of the proposed criteria sets were tested. RESULTS: The experts agreed that the criteria sets should be applied in a population with pain, aching or stiffness in hand joint(s) not explained by another disease or acute injury. In this setting, five additional criteria were considered important: age, morning stiffness, radiographic osteophytes, radiographic joint space narrowing and concordance between symptoms and radiographic findings. The reliability and validity were very good. CONCLUSION: Radiographic features were considered critical when determining whether a patient had symptoms due to hand OA. The consensus-based decision analysis approach in Phase 2 complemented the data-driven results from Phase 1, which will form the basis of the final classification criteria sets.

Resistance or appropriation?: Uptake of exercise after a nurse-led intervention to promote self-management for osteoarthritis.

The philosophical underpinning of trials of complex interventions is critiqued for not taking into account causal mechanisms that influence potential outcomes. In this article, we draw from in-depth interviews (with practice nurses and patients) and observations of practice meetings and consultations to investigate the outcomes of a complex intervention to promote self-management (in particular exercise) for osteoarthritis in primary care settings. We argue that nurses interpreted the intervention as underpinned by the need to educate rather than work with patients, and, drawing from Habermasian theory, we argue that expert medicalised knowledge (system) clashed with lay 'lifeworld' prerogatives in an uneven communicative arena (the consultation). In turn, the advice and instructions given to patients were not always commensurate with their 'lifeworld'. Consequently, patients struggled to embed exercise routines into their daily lives for reasons of unsuitable locality, sense-making that 'home' was an inappropriate place to exercise and using embodied knowledge to test the efficacy of exercise on pain. We conclude by arguing that using Habermasian theory helped to understand reasons why the trial failed to increase exercise levels. Our findings suggest that communication styles influence the outcomes of self-management interventions, reinforce the utility of theoretically informed qualitative research embedded within trials to improve conduct and outcomes and indicate incorporating perspectives from human geography can enhance Habermas-informed research and theorising.

The relationship between multisite peripheral joint pain and physical activity levels in older adults: A cross-sectional survey.

INTRODUCTION: Research on levels of physical activity (PA) in those with peripheral joint pain have only focused on single sites, in the knee or hips. This study investigated the levels of PA in adults with single-site and multisite peripheral joint pain compared to adults with no joint pain. METHODS: Analysis of a cross-sectional population survey mailed to adults aged ≥45 years (n = 28,443) was conducted. Respondents reported any peripheral joint pain in the last 12 months in either the hands, hips, knees or feet; PA levels were self-reported using the short telephone activity rating scale. The association between PA levels, peripheral joint pain and outcomes of health status (physical and mental component scores, using SF-12) pain intensity (10-point scale) and health-related quality of life (HRQoL) (EQ-5D) were investigated using analysis of variance and ordinal regressions. RESULTS: Compared to those with no joint pain, all pain groups reported lower levels of PA: joint pain in one site (odds ratio = 0.91, 95% CI: 0.83-0.99); two sites (0.74, 0.67-0.81), three sites (0.65, 0.59-0.72) and four sites (0.47, 0.42-0.53). Across all joint pain groups, levels of PA were associated with pain intensity, physical health status, mental health status and HRQoL. DISCUSSION: Adults with more sites of peripheral joint pain were more likely to report lower levels of PA. Those with more sites of pain and lower levels of PA reported poorer outcomes. Health care providers should be aware that those with multisite joint pain are most likely to have low levels of PA.

Integrating case-finding and initial management for osteoarthritis, anxiety, and depression into primary care long-term condition reviews: results from the ENHANCE pilot trial.

BACKGROUND: Multimorbidity is increasingly the norm; however, primary care remains focused on single diseases. Osteoarthritis, anxiety, and depression are frequently comorbid with other long-term conditions (LTCs), but rarely prioritized by clinicians. OBJECTIVES: To test the feasibility of a randomized controlled trial (RCT) of an intervention integrating case-finding and management for osteoarthritis, anxiety, and depression within LTC reviews. METHODS: A pilot stepped-wedge RCT across 4 general practices recruited patients aged ≥45 years attending routine LTC reviews. General practice nurses provided usual LTC reviews (control period), then, following training, delivered the ENHANCE LTC review (intervention period). Questionnaires, an ENHANCE EMIS-embedded template and consultation audio-recordings, were used in the evaluation. RESULTS: General practice recruitment and training attendance reached prespecified success criteria. Three hundred and eighteen of 466 (68%) of patients invited responded; however, more patients were recruited during the control period (206 control, 112 intervention). Eighty-two percent and 78% returned their 6-week and 6-month questionnaires, respectively. Integration of the ENHANCE LTC review into routine LTC reviews varied. Case-finding questions were generally used as intended for joint pain, but to a lesser extent for anxiety and depression. Initial management through referrals and signposting were lacking, and advice was more frequently provided for joint pain. The stepped-wedge design meant timing of the training was challenging and yielded differential recruitment. CONCLUSION: This pilot trial suggests that it is feasible to deliver a fully powered trial in primary care. Areas to optimize include improving the training and reconsidering the stepped-wedge design and the approach to recruitment by targeting those with greatest need.

Development, spread and impact of primary care and musculoskeletal communities of practice to assist rapid translation of evidence into practice.

BACKGROUND: Embedding research into practice is challenging. Barriers include: a shortage of time, lack of understanding of the evidence and a poor support in the clinical setting. A community of practice (CoP) model has been used to address these issues. Three 'Evidence into Practice' groups use a CoP model to assist the rapid translation of evidence into practice in primary and secondary care settings. We describe how a CoP model supports the functions, operations and outputs of three 'Evidence into Practice Groups'. METHOD: A CoP model is used to engage a broad range of clinicians, researchers, managers, patients and librarians in the complex process of acquiring research knowledge and then translating knowledge into practice. The CoP principles of Domain, Community and Practice are used to describe three 'Evidence into Practice Groups' who cater for different elements of the care and academic sector and engage a range of professional groups. This includes primary and secondary care engaging professionals such as general practitioners (GP), practice nurses, allied health professionals, researchers and librarians. All groups are clinically led, academically supported and follow similar processes to identify the best evidence and translate it into practice. As the groups reflect the context in which they work they have different operational arrangements for example frequency and time of meetings. RESULTS: The CoP model enabled three 'Evidence into Practice Groups' over time to: engage over 180 clinical and academic staff; answer 130 clinical questions; improve clinical care, gain funding for two randomised controlled trials (enrolled over n = 7000 participants) and identify areas for further research, quality improvement audit and training. CONCLUSION: The CoP model encourages the rapid translation of evidence into practice by engaging staff to identify areas of clinical concern in their own context, thereby stimulating their interest and involvement. This creates a meaningful link between research and practice. Clinical leadership and the CoP model ensure that practice change is quick and efficient. This model can be replicated at scale. Consideration needs to be given to the key ingredients to achieve impact.

Improving osteoarthritis management in primary healthcare: results from a quasi-experimental study.

BACKGROUND: To improve quality of care for patients with hip and knee osteoarthritis (OA), general practitioners (GPs) and physiotherapists (PTs) in a Norwegian municipality initiated an intervention. The intervention aimed to increase provision of core OA treatment (information, exercise, and weight control) prior to referral for surgery, rational use of imaging for assessing OA and improve communication between healthcare professionals. This study assessed the effectiveness of this intervention. METHODS: Forty-eight PTs and one hundred one GPs were invited to the intervention that included two interactive workshops outlining best practice and an accompanying template for PT discharge reports. Using interrupted time series research design, the study period was divided into three: pre-implementation, transition (implementation) and post-implementation. Comparing the change between pre- and post-implementation, the primary outcome was patient-reported quality of OA care measured with the OsteoArthritis Quality Indicator questionnaire. Secondary outcomes were number of PT discharge reports, information included in GP referral letters to orthopaedic surgeon, the proportion of GP referral letters indicating use of core treatment, and the use of imaging within OA assessment. Analyses involved linear mixed and logistic regression models. RESULTS: The PT workshop had 30 attendees, and 31 PTs and 33 GPs attended the multidisciplinary workshop. Two hundred eight and one hundred twenty-five patients completed the questionnaire during pre- and post-implementation, respectively. The adjusted model showed a small, statistically non-significant, increase in mean total score for quality of OA care (mean change = 4.96, 95% CI -0.18, 10.12, p:0.057), which was mainly related to items on OA core treatment. Patients had higher odds of reporting receipt of information on treatment alternatives (odds ratio (OR) 1.9, 95% CI 1.08, 3.24) and on self-management (OR 2.4, 95% CI 1.33, 4.32) in the post-implementation phase. There was a small, statistically non-significant, increase in the proportion of GP referral letters indicating prior use of core treatment modalities. There were negligible changes in the number of PT discharge reports, in the information included in the GP referral letters, and in the use of imaging for OA assessment. CONCLUSION: This study suggests that a primary care intervention including two inter-active workshops can shift the quality of care towards best practice recommendations.

Physiotherapists may improve management of knee osteoarthritis through greater psychosocial focus, being proactive with advice, and offering longer-term reviews: a qualitative study.

QUESTIONS: What are the experiences of physiotherapists delivering care for people with knee osteoarthritis? How do these experiences align with the national Clinical Care Standard? DESIGN: A qualitative study using individual interviews. PARTICIPANTS: Twenty-two Australian physiotherapists (mean age 34 years, 50% female) with experience in providing care for people with knee osteoarthritis. METHODS: Physiotherapists participated in semi-structured individual telephone interviews. Questions were informed by seven quality statements from the national Knee Osteoarthritis Clinical Care Standard. Thematic analysis was undertaken, with themes/subthemes inductively derived. Interview data were also deductively analysed according to the Clinical Care Standard. RESULTS: Five themes emerged. First, physiotherapists focused on biomedical assessment with little psychosocial consideration. They managed 'mechanical' aspects of knee osteoarthritis, aiming to restore functional ability. Second, physiotherapists' perceived their role as primarily providing goal-orientated personalised exercise via short-term episodic care. Knee surgery was considered a last option, but physiotherapists 'prepped' patients who decided on surgery. Third, clinical challenges included patient comorbidity, unsatisfactory patient adherence and a patient's desire for a 'quick fix'. The other two themes were: physiotherapists described a mismatch between what they know and what they do regarding imaging, weight management and manual therapy; and physiotherapists viewed weight loss, medication and surgical advice as outside of their professional role. CONCLUSION: Physiotherapists' reported experiences of delivering care for people with knee osteoarthritis were mostly consistent with the quality care standard. Care may be improved by increasing the focus on psychosocial aspects of care, offering longer-term reviews, and being more proactive with advice and/or referral regarding weight loss, pain medications and knee surgery. By describing the potential benefits and harms of common osteoarthritis medications and surgical interventions, physiotherapists will ensure that their patients are fully informed about all their treatment options.

Core and adjunctive interventions for osteoarthritis: efficacy and models for implementation.

Osteoarthritis (OA) is a complex musculoskeletal disease and a leading cause of pain and disability worldwide. Hip and knee OA alone are major contributors to global disability, having notable effects on individual well-being, increasing the reliance of individuals on health-care services and contributing to a rise in the socioeconomic burden. Consistent, coordinated and tailored approaches are important for providing appropriate care to all people with OA, but despite the scale of the challenge many individuals are still not offered the safe, best-evidence treatments recommended for OA care. This Review discusses the core priority treatments for OA, including exercise and physical activity, weight-loss, education and support for self-management. Additional physical or psychological evidence-based adjunctive therapies and combined therapies that can be used to tailor individual programmes are also discussed. These options include cognitive behavioural therapy, heat therapy, walking aids and splints, manual therapies and transcutaneous electrical nerve stimulation. International examples of OA treatment options, models of care and resources available are also given. Many challenges still need to be addressed to advance the uptake of these conditions, including further discussion around the risks and costs involved with all treatments.

Patient-reported quality indicators to evaluate physiotherapy care for hip and/or knee osteoarthritis- development and evaluation of the QUIPA tool.

BACKGROUND: There is no physiotherapy-specific quality indicator tool available to evaluate physiotherapy care for people with hip and/or knee osteoarthritis (OA). This study aimed to develop a patient-reported quality indicator tool (QUIPA) for physiotherapy management of hip and knee OA and to assess its reliability and validity. METHODS: To develop the QUIPA tool, quality indicators were initially developed based on clinical guideline recommendations most relevant to physiotherapy practice and those of an existing generic OA quality indicator tool. Draft items were then further refined using patient focus groups. Test-retest reliability, construct validity (hypothesis testing) and criterion validity were then evaluated. Sixty-five people with hip and/or knee OA attended a single physiotherapy consultation and completed the QUIPA tool one, twelve- and thirteen-weeks after. Physiotherapists (n = 9) completed the tool post-consultation. Patient test-retest reliability was assessed between weeks twelve and thirteen. Construct validity was assessed with three predefined hypotheses and criterion validity was based on agreement between physiotherapists and participants at week one. RESULTS: A draft list of 23 clinical guideline recommendations most relevant to physiotherapy was developed. Following feedback from three patient focus groups, the final QUIPA tool contained 18 items (three subscales) expressed in lay language. The test-retest reliability estimates (Cohen's Kappa) for single items ranged from 0.30-0.83 with observed agreement of 64-94%. The intraclass correlation coefficient (ICC) and 95% confidence interval (CI) for the Assessment and Management Planning subscale was 0.70 (0.54, 0.81), Core Recommended Treatments subscale was 0.84 (0.75, 0.90), Adjunctive Treatments subscale was 0.70 (0.39, 0.87) and for the total QUIPA score was 0.80 (0.69, 0.88). All predefined hypotheses regarding construct validity were confirmed. However, agreement between physiotherapists and participants for single items showed large measurement error (Cohen's Kappa estimates ranged from - 0.04-0.59) with the ICC (95% CI) for the total score being 0.11 (- 0.14, 0.34). CONCLUSIONS: The QUIPA tool showed acceptable test-retest reliability for subscales and total score but inadequate reliability for individual items. Construct validity was confirmed but criterion validity for individual items, subscales and the total score was inadequate. Further research is needed to refine the QUIPA tool to improve its clinimetric properties before implementation.

Relative prevalence and distribution of knee, hand and foot symptomatic osteoarthritis subtypes in an English population.

In this brief report, we used data from a series of three related cohorts on pain and osteoarthritis (OA) of the knee, hand and foot, which were conducted in North Staffordshire, England. We used a common approach for sampling, data collection and coding, to estimate the relative prevalence of 10 different symptomatic radiographic OA subtypes in the knee, hand and foot and to compare their association with age, sex, socioeconomic position and body mass index. Overall, symptomatic hand OA was more common than knee or foot OA (22.4% vs 17.4% vs 16.5%), due mainly to the high prevalence of nodal interphalangeal joint OA among women. The first carpometacarpal joint OA was the most frequent subtype, with patellofemoral, tibiofemoral, (nodal) interphalangeal and midfoot OA also common. Of the risk factors examined, the greatest differences between subtypes appeared to be their associations with sex and obesity: sex differences were noticeably greater for all forms of hand OA except non-nodal interphalangeal joint OA, while obesity appeared most strongly associated with forms of knee OA. The prevalence of all subtypes was higher among older ages, and among those with lower educational attainment.

Identifying and Prioritizing Clinical Guideline Recommendations Most Relevant to Physical Therapy Practice for Hip and/or Knee Osteoarthritis.

BACKGROUND: Physical therapists are key providers of conservative management for hip and/or knee osteoarthritis (OA), yet not all guideline recommendations are tailored to their scope of practice. OBJECTIVE: To identify and prioritize the most important recommendations relevant to physical therapy practice for hip and/or knee OA. METHODS: International physical therapists (n = 132) were invited to participate in an online modified Delphi survey, followed by a priority-ranking exercise. A total of 63 recommendations were extracted from 2 recent high-quality clinical guidelines. In 3 Delphi rounds, the panel identified those recommendations they considered to be most relevant to physical therapy practice for hip and knee OA. Any new recommendations were ascertained. For a recommendation to be included, at least 70% of respondents had to rate the recommendation as 7 or above on a numeric rating scale (0 is not important and 10 is extremely important). The panel prioritized recommendations that remained after the final round using decision-making software. RESULTS: Of 132 therapists from 14 countries, 62 completed round 1, 52 completed round 2, 45 completed round 3, and 35 completed the priority-ranking exercise. From an initial list of 70 potential recommendations (including 7 new recommendations), 30 were included in the priority-ranking exercise. The top recommendations were related to providing education and prescribing exercise and weight loss as core treatments, followed by individualized OA assessment and treatment and communication strategies. CONCLUSION: This study identified and ranked the most important recommendations relevant to physical therapy practice for hip and/or knee OA. J Orthop Sports Phys Ther 2019;49(7):501-512. doi:10.2519/jospt.2019.8676.

Priorities for the effective implementation of osteoarthritis management programs: an OARSI international consensus exercise.

OBJECTIVE: The Joint Effort Initiative was endorsed by Osteoarthritis Research Society International (OARSI) in 2018 as a collaboration between international researchers and clinicians with an interest in the implementation of osteoarthritis management programs (OAMPs). This study aimed to identify and prioritise activities for future work of the Joint Effort Initiative. DESIGN: A survey was emailed to delegates of the 2018 OARSI World Congress attending a pre-conference workshop or with a known interest in OAMPs (n = 115). Delegates were asked about the most important issues regarding OAMP implementation. The top 20 issues were synthesised into 17 action statements, and respondents were invited to participate in a priority ranking exercise to determine the order of importance of the statements. RESULTS: Survey respondents (n = 51, 44%) were most commonly female (71%), with an allied health background (57%), affiliated with universities (73%) from Oceania (37%), and Europe/UK (45%). The five highest ranked action statements were: CONCLUSION: Prioritising statements will bring focus to the future work of the Joint Effort Initiative in the future and provide a basis for longer-term actions.

Predictors of pain interference and potential gain from intervention in community dwelling adults with joint pain: A prospective cohort study.

INTRODUCTION: There is little research on identifying modifiable risk factors that predict future interference of pain with daily activity in people with joint pain, and the estimation of the corresponding population attributable risk (PAR). The present study therefore investigated modifiable predictors of pain interference and estimated maximum potential gain from intervention in adults with joint pain. METHODS: A population-based cohort aged ≥50 years was recruited from eight general practices in North Staffordshire, UK. Participants (n = 1878) had joint pain at baseline lasting ≥3 months and indicated no pain interference. Adjusted associations of self-reported, potentially modifiable prognostic factors (body mass index, anxiety/depressive symptoms, widespread pain, inadequate joint pain control, physical inactivity, sleep problems, smoking and alcohol intake) with onset of pain interference 3 years later were estimated via Poisson regression, and corresponding PAR estimates were obtained. RESULTS: Inadequate joint-specific pain control, insomnia and infrequent walking were found to be independently significantly associated with the onset of pain interference after 3 years, with associated PARs of 6.3% (95% confidence interval -0.3, 12.4), 7.6% (-0.4, 15.0) and 8.0% (0.1, 15.2), respectively, with only the PAR for infrequent walking deemed statistically significant. The PAR associated with insomnia, infrequent walking and inadequate control of joint pain simultaneously was 20.3% (8.6, 30.4). CONCLUSIONS: There is potential to reduce moderately the onset of pain interference from joint pain in the over-50s if clinical and public health interventions targeted pain management and insomnia, and promoted an active lifestyle. However, most of the onset of significant pain interference in the over-50s, would not be prevented, even assuming that these factors could be eliminated.

2018 update of the EULAR recommendations for the management of hand osteoarthritis.

Since publication of the European League Against Rheumatism (EULAR) recommendations for management of hand osteoarthritis (OA) in 2007 new evidence has emerged. The aim was to update these recommendations. EULAR standardised operating procedures were followed. A systematic literature review was performed, collecting the evidence regarding all non-pharmacological, pharmacological and surgical treatment options for hand OA published to date. Based on the evidence and expert opinion from an international task force of 19 physicians, healthcare professionals and patients from 10 European countries formulated overarching principles and recommendations. Level of evidence, grade of recommendation and level of agreement were allocated to each statement. Five overarching principles and 10 recommendations were agreed on. The overarching principles cover treatment goals, information provision, individualisation of treatment, shared decision-making and the need to consider multidisciplinary and multimodal (non-pharmacological, pharmacological, surgical) treatment approaches. Recommendations 1-3 cover different non-pharmacological treatment options (education, assistive devices, exercises and orthoses). Recommendations 4-8 describe the role of different pharmacological treatments, including topical treatments (preferred over systemic treatments, topical non-steroidal anti-inflammatory drugs (NSAIDs) being first-line choice), oral analgesics (particularly NSAIDs to be considered for symptom relief for a limited duration), chondroitin sulfate (for symptom relief), intra-articular glucocorticoids (generally not recommended, consider for painful interphalangeal OA) and conventional/biological disease-modifying antirheumatic drugs (discouraged). Considerations for surgery are described in recommendation 9. The last recommendation relates to follow-up. The presented EULAR recommendations provide up-to-date guidance on the management of hand OA, based on expert opinion and research evidence.

Identification and Evaluation of Self-Report Physical Activity Instruments in Adults With Osteoarthritis: A Systematic Review.

OBJECTIVE: To identify and evaluate the measurement properties of self-report physical activity instruments suitable for patients with osteoarthritis (OA). METHODS: We conducted a comprehensive 2-stage systematic review using multiple electronic databases, from inception until July 2018. In the stage 1 review, we sought to identify all self-report physical activity instruments used in individuals with joint pain attributable to OA in the foot, knee, hip, or hand. In the stage 2 review, we searched for and appraised studies investigating the measurement properties of the instruments identified. In both stages of the review, we screened all articles for study eligibility criteria, completed data extraction using the Qualitative Attributes and Measurement Properties of Physical Activity questionnaire checklist, and conducted methodology quality assessments using a modified COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) checklist. Measurement properties for each physical activity instrument were evaluated and combined, using narrative synthesis. RESULTS: In the stage 1 review, we identified 23 unique self-report physical activity instruments. In the stage 2 review, we identified 54 studies that evaluated the measurement properties of 13 of the 23 instruments identified. Instrument reliability varied from inadequate to adequate (intraclass correlation coefficient ≥0.7). Instrument construct and criterion validity assessment showed small to moderate correlations with direct measures of physical activity. Instrument responsiveness was assessed in only 1 instrument and was unable to detect changes in comparison to accelerometers. CONCLUSION: Although many instruments were identified as being potentially suitable for use in patients with OA, none demonstrated adequate measurement properties across all domains of reliability, validity, and responsiveness. Further high-quality assessment of self-report physical activity instruments is required before such measures can be recommended for use in OA research.

The clinical and cost-effectiveness of corticosteroid injection versus night splints for carpal tunnel syndrome (INSTINCTS trial): an open-label, parallel group, randomised controlled trial.

BACKGROUND: To our knowledge, the comparative effectiveness of commonly used conservative treatments for carpal tunnel syndrome has not been evaluated previously in primary care. We aimed to compare the clinical and cost-effectiveness of night splints with a corticosteroid injection with regards to reducing symptoms and improving hand function in patients with mild or moderate carpal tunnel syndrome. METHODS: We did this randomised, open-label, pragmatic trial in adults (≥18 years) with mild or moderate carpal tunnel syndrome recruited from 25 primary and community musculoskeletal clinics and services. Patients with a new episode of idiopathic mild or moderate carpal tunnel syndrome of at least 6 weeks' duration were eligible. We randomly assigned (1:1) patients (permutated blocks of two and four by site) with an online web or third party telephone service to receive either a single injection of 20 mg methylprednisolone acetate (from 40 mg/mL) or a night-resting splint to be worn for 6 weeks. Patients and clinicians could not be masked to the intervention. The primary outcome was the overall score of the Boston Carpal Tunnel Questionnaire (BCTQ) at 6 weeks. We used intention-to-treat analysis, with multiple imputation for missing data, which was concealed to treatment group allocation. The trial is registered with the European Clinical Trials Database, number 2013-001435-48, and ClinicalTrial.gov, number NCT02038452. FINDINGS: Between April 17, 2014, and Dec 31, 2016, 234 participants were randomly assigned (118 to the night splint group and 116 to the corticosteroid injection group), of whom 212 (91%) completed the BCTQ at 6 weeks. The BCTQ score was significantly better at 6 weeks in the corticosteroid injection group (mean 2·02 [SD 0·81]) than the night splint group (2·29 [0·75]; adjusted mean difference -0·32; 95% CI -0·48 to -0·16; p=0·0001). No adverse events were reported. INTERPRETATION: A single corticosteroid injection shows superior clinical effectiveness at 6 weeks compared with night-resting splints, making it the treatment of choice for rapid symptom response in mild or moderate carpal tunnel syndrome presenting in primary care.

Uptake of the NICE osteoarthritis guidelines in primary care: a survey of older adults with joint pain.

BACKGROUND: Osteoarthritis (OA) is a leading cause of pain and disability. NICE OA guidelines (2008) recommend that patients with OA should be offered core treatments in primary care. Assessments of OA management have identified a need to improve primary care of people with OA, as recorded use of interventions concordant with the NICE guidelines is suboptimal in primary care. The aim of this study was to i) describe the patient-reported uptake of non-pharmacological and pharmacological treatments recommended in the NICE OA guidelines in older adults with a self-reported consultation for joint pain and ii) determine whether patient characteristics or OA diagnosis impact uptake. METHODS: A cross-sectional survey mailed to adults aged ≥45 years (n = 28,443) from eight general practices in the UK as part of the MOSAICS study. Respondents who reported the presence of joint pain, a consultation in the previous 12 months for joint pain, and gave consent to medical record review formed the sample for this study. RESULTS: Four thousand fifty-nine respondents were included in the analysis (mean age 65.6 years (SD 11.2), 2300 (56.7%) females). 502 (12.4%) received an OA diagnosis in the previous 12 months. More participants reported using pharmacological treatments (e.g. paracetamol (31.3%), opioids (40.4%)) than non-pharmacological treatments (e.g. exercise (3.8%)). Those with an OA diagnosis were more likely to use written information (OR 1.57; 95% CI 1.26,1.96), paracetamol (OR 1.30; 95% CI 1.05,1.62) and topical NSAIDs (OR 1.30; 95% CI 1.04,1.62) than those with a joint pain code. People aged ≥75 years were less likely to use written information (OR 0.56; 95% CI 0.40,0.79) and exercise (OR 0.37; 95% CI 0.25,0.55) and more likely to use paracetamol (OR 1.91; 95% CI 1.38,2.65) than those aged < 75 years. CONCLUSION: The cross-sectional population survey was conducted to examine the uptake of the treatments that are recommended in the NICE OA guidelines in older adults with a self-reported consultation for joint pain and to determine whether patient characteristics or OA diagnosis impact uptake. Non-pharmacological treatment was suboptimal compared to pharmacological treatment. Implementation of NICE guidelines needs to examine why non-pharmacological treatments, such as exercise, remain under-used especially among older people.
