Abstract
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. TRIAL REGISTRATION NUMBER ClinicalTrials.gov NCT02333656.

Abstract
OBJECTIVES The etiology of fibromyalgia (FM) is disputed, and there is no established cure. Quantitative data on how this may affect patients' healthcare experiences are scarce. The present study aims to investigate FM patients' pain-related healthcare experiences and explore factors associated with high satisfaction and pain relief. METHODS An anonymous, online, and patient-administered survey was developed and distributed to members of the Norwegian Fibromyalgia Association. It addressed their pain-related healthcare experiences from both primary and specialist care. Odds ratios for healthcare satisfaction and pain relief were estimated by binary logistic regression. Directed acyclic graphs guided the multivariable analyses. RESULTS The patients (n = 1,626, mean age: 51 years) were primarily women (95%) with a 21.8-year mean pain duration and 12.7 years in pain before diagnosis. One-third did not understand why they had pain, and 56.6% did not know how to get better. More than half had not received satisfactory information on their pain cause from a physician, and guidance on how to improve was reported below medium. Patients regretted a lack of medical specialized competence on muscle pain and reported many unmet needs, including regular follow-up and pain assessment. Physician-mediated pain relief was low, and guideline adherence was deficient. Only 14.8% were satisfied with non-physician health providers evaluating and treating their pain, and 21.5% were satisfied (46.9% dissatisfied) with their global pain-related healthcare. Patients' knowledge of their condition, physicians' pain competence and provision of information and guidance, agreement in explanations and advice, and the absence of unmet needs significantly increased the odds of both healthcare satisfaction and pain relief. CONCLUSIONS Our survey describes deficiencies in FM patients' pain-related healthcare and suggests areas for improvement to increase healthcare satisfaction and pain relief.

Abstract
BACKGROUND The impact of long-term dizziness is considerable both on the personal level and in society and may lead to self-imposed restrictions in daily activities and social relations due to fear of triggering the symptoms. Musculoskeletal complaints seem to be common in persons with dizziness, but studies addressing these complaints as a widespread occurrence, are scarce. This study aimed to examine the occurrence of widespread pain in patients with long-term dizziness and investigate the associations between pain and dizziness symptoms. Further, to explore whether diagnostic belonging is related to the occurrence of pain. METHODS This cross-sectional study was conducted in an otorhinolaryngology clinic and included 150 patients with persistent dizziness. The patients were categorized into three groups: episodic vestibular syndromes, chronic vestibular syndromes, and non-vestibular group. The patients completed questionnaires on dizziness symptoms, catastrophic thinking, and musculoskeletal pain when entering the study. Descriptive statistics were used to describe the population, and associations between pain and dizziness were investigated by linear regression. RESULTS Pain was reported by 94.5% of the patients. A significantly higher prevalence of pain was reported in all the ten pain sites examined compared to the general population. Number of pain sites and pain intensity were associated with the dizziness severity. Number of pain sites was also associated with dizziness-related handicap, but not with catastrophic thinking. There was no association between pain intensity and dizziness-related handicap or catastrophic thinking. Pain was equally distributed in the diagnostic groups. CONCLUSION Patients with long-term dizziness have a considerably higher prevalence of pain and number of pain sites than the general population. Pain co-exists with dizziness and is associated with dizziness severity. These findings may indicate that pain should be systematically assessed and treated in patients with persisting dizziness.

Abstract
Background The dynamic nature of neck pain has so far been identified through longitudinal studies with frequent measures, a method which is time-consuming and impractical. Pictures illustrating different courses of pain may be an alternative solution, usable in both clinical work and research, but it is unknown how well they capture the clinical course. The aim of this study was to explore and describe self-reported visual trajectories in terms of details of patients’ prospectively reported clinical course, their SMS-based pattern classification of neck pain, and patient’s characteristics. Methods Prospective cohort study including 888 neck pain patients from chiropractic practice, responding to weekly SMS-questions about pain intensity for 1 year from 2015 to 2017. Patients were classified into one of three clinical course patterns using definitions based on previously published descriptors. At 1-year follow-up, patients selected a visual trajectory that best represented their retrospective 1-year course of pain: single episode, episodic, mild ongoing, fluctuating and severe ongoing. Results The visual trajectories generally resembled the 1-year clinical course characteristics on group level, but there were large individual variations. Patients selecting Episodic and Mild ongoing visual trajectories were similar on most parameters. The visual trajectories generally resembled more the clinical course of the last quarter. Discussion The visual trajectories reflected the descriptors of the clinical course of pain captured by weekly SMS measures on a group level and formed groups of patients that differed on symptoms and characteristics. However, there were large variations in symptoms and characteristics within, as well as overlap between, each visual trajectory. In particular, patients with mild pain seemed predisposed to recall bias. Although the visual trajectories and SMS-based classifications appear related, visual trajectories likely capture more elements of the pain experience than just the course of pain. Therefore, they cannot be seen as a proxy for SMS-tracking of pain over 1 year. Supplementary Information The online version contains supplementary material available at 10.1186/s12998-022-00443-3.

Abstract
Objective To describe and compare patients with neck or back pain treated by physiotherapists in primary healthcare (PHC) and in departments for physical medicine and rehabilitation in specialist healthcare (SHC) in Norway. Design Cross-sectional study using data from the FYSIOPRIM (FP) database in PHC and the Norwegian Neck and Back Registry (NPR) in SHC. Neck and back pain patients in the period 2014–18 aged ≥ 18 years were included. Demographics, lifestyle and clinical factors were investigated. Results A total of 8,125 patients were included: 584 in PHC and 7,541 in SHC. Mean age was 47.1 and 45.5 years, respectively, with more females in PHC (72% vs 56%). Low levels of education and physical activity, high workload and receiving social benefits were associated with treatment in SHC. Treatment in SHC was most common among patients with pain duration 3 to 12 months. Higher pain intensity and lower health-related quality of life were found in patients treated in SHC, no differences were found for psychological distress. Conclusion This is the first study comparing register data in patients with neck or back pain treated in PHC and SHC. Differences were found in pain and health-related quality of life, but levels of psychological distress were similar between patients treated in PHC and those treated in SHC.

Abstract
OBJECTIVE To explore associations between general practice patients' SRH and symptoms, diagnoses, chronic conditions, unexplained conditions, and life stressors. DESIGN A cross-sectional study. Data were collected from GP and patient questionnaires. SETTING General practices in Southeast Norway. SUBJECTS 47 general practitioners (GPs) who included 866 consecutive patients. MAIN OUTCOME MEASURES SRH was measured with a single question from the COOP-WONCA overall health chart and dichotomized into good/poor SRH. Binary logistic regression models were used in the analyses. RESULTS Poor SRH was reported by 48% of the patients in the past week. A higher prevalence of poor SRH was found for women, middle-aged, recipients of social security grants, patients diagnosed with asthenia, lower back pain, and depression/anxiety, and for patients with reported life stressors and unexplained conditions. We found an almost linear association between the number of symptoms and the likelihood of reporting poor SRH. The probability of reporting poor SRH increased along with an increasing number of symptoms for common diagnoses. In a multivariate analysis, the only number of symptoms, being in receipt of social security grants and being retired was associated with poor SRH. CONCLUSION The likelihood of reporting poor SRH increased with an increasing number of symptoms, partly independent of the diagnosis given by GPs. This result coincides with our previous findings of a strong association between the number of symptoms, function, and health. The symptom burden thus appears to be an important factor for SRH among patients in general practice.KEY POINTSThere is a high prevalence of poor SRH in general practice patients.The likelihood of reporting poor SRH is partly independent of the diagnosis given.The number of symptoms was the factor strongest associated with poor SRH.

Abstract
OBJECTIVES The Fibromyalgia Survey Diagnostic Criteria-2016 (FSD-2016 criteria) were recently recommended for both clinical and research purposes. The present study aims to examine whether there is concordance between clinician-based and FSD-2016 criteria-based diagnoses of FM, and secondly, to examine how the illness severity and physical function relate to the criteria-based diagnosis among patients referred to a rheumatism hospital. METHODS Participants with a clinician-based diagnosis of FM were included consecutively when referred to a patient education programme for patients with FM. Illness severity was assessed with the Fibromyalgia Survey Questionnaire (FSQ). Based on the FSQ, the fulfilment of the FSD-2016 criteria was evaluated. Physical function was assessed using the Fibromyalgia Impact Questionnaire (FIQ) function scale and self-reported employment status. RESULTS The sample included 130 patients (84% women) from 20 to 66 years of age. Eighty-nine per cent met the FSD-2016 criteria, and 44% of the patients were fully or partially employed. Great variability in illness severity was seen irrespective of employment status. There was an association between illness severity and physical function (r=0.4, p<0.001). For 95% of the patients, the FSQ illness severity scores classify as severe or very severe, and even for those not fulfilling the diagnostic criteria the scores were moderate and severe. CONCLUSIONS There was relatively high agreement between clinician- and criteria-based diagnoses. The illness severity overlapped irrespective of different employment status and fulfilment of FSD-2016 criteria.

Abstract
INTRODUCTION Research suggests that current care for shoulder pain is not in line with the best available evidence. This project aims to assess the effectiveness, cost-effectiveness and the implementation of an evidence-based guideline for shoulder pain in general practice in Norway. METHODS AND ANALYSIS A stepped-wedge, cluster-randomised trial with a hybrid design assessing clinical effectiveness, cost-effectiveness and the effect of the implementation strategy of a guideline-based intervention in general practice. We will recruit at least 36 general practitioners (GPs) and randomise the time of cross-over from treatment as usual to the implemented intervention. The intervention includes an educational outreach visit to the GPs, a computerised decision tool for GPs and a self-management application for patients. We will measure outcomes at patient and GP levels using self-report questionnaires, focus group interviews and register based data. The primary outcome measure is the patient-reported Shoulder Pain and Disability Index measured at 12 weeks. Secondary outcomes include the EuroQol Quality of Life Measure (EQ5D-5L), direct and indirect costs, patient's global perceived effect of treatment outcome, Pain Self-Efficacy and Brief Illness Perception Questionnaire. We will evaluate the implementation process with focus on adherence to guideline treatment. We will do a cost-minimisation analysis based on direct and selected indirect costs and a cost-utility analysis based on EQ5D-5L. We will use mixed effect models to analyse primary and secondary outcomes. ETHICS AND DISSEMINATION Ethics approval was granted by the Regional Committee for Medical and Health Research Ethics-South East Norway (ref. no: 2019/104). Trial results will be submitted for publication in a peer-reviewed medical journal in accordance with Consolidated Standards of Reporting Trials. TRIAL REGISTRATION NUMBER NCT04806191.

Abstract
Background:To ensure delivery of high-quality osteoarthritis (OA) care, structured care models incorporating patient education and exercise are increasingly implemented in primary care 1. A goal is to improve patients’ physical function and coping with daily life demands and activities. Yet, there is limited knowledge regarding the type and severity of activity limitations experienced by people with hip and knee OA.Objectives:1) To map activity limitations reported by patients with hip and knee OA participating in a research study implementing an OA care model in primary care. 2) To investigate potential changes in self-reported difficulty performing these activities from baseline to 12-weeks follow-up.Methods:A structured OA care model was implemented in six Norwegian municipalities between January 2015 and October 2017, using a stepped-wedge cluster-randomized controlled design. Implementation was facilitated by interactive workshops for general practitioners and physiotherapists (PTs). The PTs provided a 3-hour, group-based patient education program followed by individually tailored 8-12 weeks exercise with twice weekly 1-hour supervised group sessions. Patients with clinically or radiologically verified symptomatic hip or knee OA ≥45 years were eligible. Patients who received the new model of care completed the Patient-Specific Functional Scale (PSFS) at baseline by identifying between one and three “important activities that you are unable to do or are having difficulty with because of your hip or knee OA”. The patients rated their performance of the reported activities on an 11-point numeric rating scale (NRS) ranging from 0 (unable to perform activity) to 10 (perform activity with no problems). After 12 weeks the patients re-rated their previously identified activities. The reported activities were linked to the International Classification of Functioning, Disability and Health (ICF) at Chapter and Domain (second and third) level. Absolute change in scores from baseline to follow-up was calculated as the mean score of the reported activities. Change from baseline to follow-up was investigated using paired samples t-test. P-value was set to <0.05. Clinically important change was regarded 2 points on the 0-10 scale.Results:A total of 284 patients received the new model of care. The mean age was 63 (SD 10) years, and 211 (74%) were female. The main affected OA joint was the knee for 174 (61%), the hip for 100 (35%) and other joints (e.g. hand) for 9 (3%). The PSFS was completed by 152 (53%) patients, of which 13 reported one, 42 reported two and 97 reported three activities. A total of 382 activities were linked with ICF. Of these, 362 (95%) were linked to the Activities and Participation chapter (D). On second-level, 318 (83%) activities were linked to the Mobility domain (D4). On the third-level, the majority of activities were linked to the domains Changing body positions (d410) (26%), Walking (d450) (23%) and Moving around (d455) (25%). The patients reported significantly less difficulty performing their self-reported activities at 12 week follow-up (4.1 (SD 1.7) versus 6.3 (SD 1.8), mean change 2.1 (95% CI 1.8, 2.5), p<0.001).Conclusion:The majority of activity limitations reported by patients receiving a structured OA care model in primary care were within the ICF Mobility domain. The most common third-level ICF domains were Changing body positions, Walking and Moving around. After participating in OA patient education and structured 8-12 weeks of exercise, the patients reported a statistically significant and clinically important improvement in the difficulty of performing their individual activities.References:[1]Allen KD, Choong PF, Davis AM, et al.

Abstract
OBJECTIVE To describe self-reported symptoms among patients in general practice and to explore the relationships between symptoms experienced by patients and diagnoses given by general practitioners. DESIGN Doctor-patient questionnaires focusing on patients' self-reported symptoms during the past 7 days and the doctors' diagnoses. SETTING General practices in urban and suburban areas in Southeast Norway. SUBJECTS Forty-seven general practitioners who included 866 patients aged ≥18 years on a random day in practice. RESULTS The most frequently reported symptoms were tiredness (46%), lower back pain (43%), neck pain (41%), headache (39%), shoulder pain (36%), and sleep problems (35%). Women had a significantly higher prevalence than men for 16 of 38 symptoms (p < 0.05). The mean number of symptoms was 7.5 (range, 0-32; women, 8.1; men, 6.5, p < 0.05). Regression analysis showed that patients who received a social security grant had 59% more symptoms than those who were employed and that people with asthenia and depression/anxiety had 44% and 23% more symptoms, respectively than those with all other diagnoses. The patterns of symptoms reported showed similar patterns across the five most prevalent diagnoses. CONCLUSIONS Patients in general practice report a number of symptoms and share a common pattern of symptoms, which appear to be partly independent of the diagnoses given. These findings suggest that symptoms are not necessarily an indication of disease.KEY POINTSPatients consulting general practitioners have a high number of self-reported symptoms.The most frequent symptoms are tiredness, lower back pain, neck pain, headache, shoulder pain, and sleep problems.Patients diagnosed with asthenia and depression/anxiety report the highest number of symptoms.Selected diagnoses show similar patterns in symptom distribution.Symptoms are not necessarily an indication of disease.

Abstract
Background:To improve quality of care for patients with hip and knee osteoarthritis (OA), a structured model for integrated OA care was developed based on international treatment recommendations. A previous analysis of a cluster RCT (cRCT) showed that compared to usual care, the intervention group reported higher quality of care and greater satisfaction with care. Also, more patients were treated according to international guidelines and fulfilled recommendations for physical activity at the 6-month follow-up.Objectives:To assess the cost-utility of a structured model for hip or knee OA care.Methods:A cRCT with stepped-wedge cohort design was conducted in 6 Norwegian municipalities (clusters) in 2015-17. The OA care model was implemented in one cluster at the time by switching from “usual care” to the structured model. The implementation of the model was facilitated by interactive workshops for general practitioners (GPs) and physiotherapists (PTs) with an update on OA treatment recommendations. The GPs explained the OA diagnosis and treatment alternatives, provided pharmacological treatment when appropriate, and suggested referral to physiotherapy. The PT-led patient OA education programme was group-based and lasted 3 hours followed by an 8–12-week individually tailored resistance exercise programme with twice weekly 1-hour supervised group sessions (5–10 patients per PT). An optional 10-hours Healthy Eating Program was available. Participants were ≥45 years with symptomatic hip or knee OA.Costs were measured from the healthcare perspective and collected from several sources. Patients self-reported visits in primary healthcare at 3, 6, 9 and 12 months. Secondary healthcare visits and joint surgery data were extracted from the Norwegian Patient Register. The health outcome, quality-adjusted life-year (QALY), was estimated based on the EQ-5D-5L scores at baseline, 3, 6, 9 and 12 months. The result of the cost-utility analysis was reported using the incremental cost-effectiveness ratio (ICER), defined as the incremental costs relative to incremental QALYs (QALYs gained). Based on Norwegian guidelines, the threshold is €27500. Sensitivity analyses were performed using bootstrapping to assess the robustness of reported results and presented in a cost-effectiveness plane (Figure 1).Results:The 393 patients’ mean age was 63 years (SD 9.6) and 74% were women. 109 patients were recruited during control periods (control group), and 284 patients were recruited during interventions periods (intervention group). Only the intervention group had a significant increase in EQ-5D-5L utility scores from baseline to 12 months follow-up (mean change 0.03; 95% CI 0.01, 0.05) with QALYs gained: 0.02 (95% CI -0.08, 0.12). The structured OA model cost approx. €301 p.p. with an additional €50 for the Healthy Eating Program. Total 12 months healthcare cost p.p. was €1281 in the intervention and €3147 in the control group, resulting in an incremental cost of -€1866 (95% CI -3147, -584) p.p. Costs related to surgical procedures had the largest impact on total healthcare costs in both groups. During the 12-months follow-up period, 5% (n=14) in the intervention compared to 12% (n=13) in the control group underwent joint surgery; resulting in a mean surgical procedure cost of €553 p.p. in the intervention as compared to €1624 p.p. in the control group. The ICER was -€93300, indicating that the OA care model resulted in QALYs gained and cost-savings. At a threshold of €27500, it is 99% likely that the OA care model is a cost-effective alternative.Conclusion:The results of the cost-utility analysis show that implementing a structured model for OA care in primary healthcare based on international guidelines is highly likely a cost-effective alternative compared to usual care for people with hip and knee OA. More studies are needed to confirm this finding, but this study results indicate that implementing structured OA care models in primary healthcare may be beneficial for the individual as well as for the society.Disclosure of Interests:None declared

Abstract
INTRODUCTION Traumatic injuries constitute a major cause of mortality and morbidity. Still, the public health burden of trauma in Norway has not been characterised using nationwide registry data. More knowledge is warranted on trauma risk factors and the long-term outcomes following trauma. The Injury Prevention and long-term Outcomes following Trauma project will establish a comprehensive research database. The Norwegian National Trauma Registry (NTR) will be merged with several data sources to pursue the following three main research topics: (1) the public health burden of trauma to society (eg, excess mortality and disability-adjusted life-years (DALYs)), (2) trauma aetiology (eg, socioeconomic factors, comorbidity and drug use) and (3) trauma survivorship (eg, survival, drug use, use of welfare benefits, work ability, education and income). METHODS AND ANALYSIS The NTR (n≈27 000 trauma patients, 2015-2018) will be coupled with the data from Statistics Norway, the Norwegian Patient Registry, the Cause of Death Registry, the Registry of Primary Health Care and the Norwegian Prescription Database. To quantify the public health burden, DALYs will be calculated from the NTR. To address trauma aetiology, we will conduct nested case-control studies with 10 trauma-free controls (drawn from the National Population Register) matched to each trauma case on birth year, sex and index date. Conditional logistic regression models will be used to estimate trauma risk according to relevant exposures. To address trauma survivorship, we will use cohort and matched cohort designs and time-to-event analyses to examine various post-trauma outcomes. ETHICS AND DISSEMINATION The project is approved by the Regional Committee for Medical Research Ethics. The project's data protection impact assessment is approved by the data protection officer. Results will be disseminated to patients, in peer-reviewed journals, at conferences and in the media.

Abstract
BACKGROUND Co-occurring musculoskeletal pain is common among people with persistent low back pain (LBP) and associated with more negative consequences than LBP alone. The distribution and prevalence of musculoskeletal pain co-occurring with persistent LBP has not been systematically described, which hence was the aim of this review. METHODS Literature searches were performed in MEDLINE, Embase, CINAHL and Scopus. We considered observational studies from clinical settings or based on cohorts of the general or working populations involving adults 18 years or older with persistent LBP (≥4 wks) and co-occurring musculoskeletal pain for eligibility. Study selection, data extraction and risk of bias assessment were carried out by independent reviewers. Results are presented according to study population, distribution and location(s) of co-occurring pain. RESULTS Nineteen studies out of 5744 unique records met the inclusion criteria. Studies were from high-income countries in Europe, USA and Japan. A total of 34,492 people with persistent LBP were included in our evidence synthesis. Methods for assessing and categorizing co-occurring pain varied considerably between studies, but based on the available data from observational studies, we identified three main categories of co-occurring pain - these were axial pain (18 to 58%), extremity pain (6 to 50%), and multi-site musculoskeletal pain (10 to 89%). Persistent LBP with co-occurring pain was reported more often by females than males, and co-occurring pain was reported more often in patients with more disability. CONCLUSIONS People with persistent LBP often report co-occurring neck pain, extremity pain or multi-site pain. Assessment of co-occurring pain alongside persistent LBP vary considerable between studies and there is a need for harmonisation of measurement methods to advance our understanding of how pain in different body regions occur alongside persistent LBP.

Abstract
BACKGROUND Neck and low back pain represent dynamic conditions that change over time, often with an initial improvement after the onset of a new episode, followed by flare-ups or variations in intensity. Pain trajectories were previously defined based on longitudinal studies of temporal patterns and pain intensity of individuals with low back pain. In this study, we aimed to 1) investigate if the defined patterns and subgroups for low back pain were applicable to neck pain patients in chiropractic practice, 2) explore the robustness of the defined patterns, and 3) investigate if patients within the various patterns differ concerning characteristics and clinical findings. METHODS Prospective cohort study including 1208 neck pain patients from chiropractic practice. Patients responded to weekly SMS-questions about pain intensity and frequency over 43 weeks. We categorized individual responses into four main patterns based on number of days with pain and variations in pain intensity, and subdivided each into four subgroups based on pain intensity, resulting in 16 trajectory subgroups. We compared baseline characteristics and clinical findings between patterns and between Persistent fluctuating and Episodic subgroups. RESULTS All but two patients could be classified into one of the 16 subgroups, with 94% in the Persistent fluctuating or Episodic patterns. In the largest subgroup, "Mild Persistent fluctuating" (25%), mean (SD) pain intensity was 3.4 (0.6) and mean days with pain 130. Patients grouped as "Moderate Episodic" (24%) reported a mean pain intensity of 2.7 (0.6) and 39 days with pain. Eight of the 16 subgroups each contained less than 1% of the cohort. Patients in the Persistent fluctuating pattern scored higher than the other patterns in terms of reduced function and psychosocial factors. CONCLUSIONS The same subgroups seem to fit neck and low back pain patients, with pain that typically persists and varies in intensity or is episodic. Patients in a Persistent fluctuating pattern are more bothered by their pain than those in other patterns. The low back pain definitions can be used on patients with neck pain, but with the majority of patients classified into 8 subgroups, there seems to be a redundancy in the original model.

Abstract
BACKGROUND A novel approach capturing both temporal variation and pain intensity of neck pain is by visual trajectory patterns. Recently, both previous and expected visual trajectory patterns were identified as stronger predictors of outcome than traditional measures of pain history and psychological distress. Our aim was to examine patient characteristics within the various previous and expected patterns, relationship between the two patterns and predictive value of a variable combining the previous and expected patterns. METHODS Patients with neck pain (n = 932) consulting chiropractors were included. Baseline measures included pain intensity, disability, psychological variables and symptom history and expectations. Participants reported global perceived effect after 12 weeks. Analyses included descriptive statistics and logistic regression. RESULTS Pain intensity, disability, psychological and worse outcome expectations increased from a single pain episode to severe ongoing pain of previous and expected patterns. Having a severe pain history was associated with poor prognosis, particularly if combined with negative expectations. The variable combining previous and expected patterns had a discriminative ability similar to that of other predictors AUC = 0.64 (95% CI = 0.60-0-67) versus AUC = 0.66 (95% CI = 0.62-0.70). The model with highest discriminative ability was achieved when adding the combined patterns to other predictors AUC = 0.70 (95% CI = 0.66-0.73). CONCLUSION The study indicates that pain expectations are formed by pain history. The patients' expectations were similar to or more optimistic compared with their pain history. The prognostic ability of the model including a simplified combination of previous and expected patterns, together with a few other predictors, suggests that the trajectory patterns might have potential for clinical use. SIGNIFICANCE The dynamic nature of neck pain can be captured by visual illustrations of trajectory patterns. We report, that trajectory patterns of pain history and future expectations to some extent are related. The patterns also reflect a difference in severity assessed by higher degree of symptoms and distress. Moreover, the visual trajectory patterns predict outcome at 12-weeks. Since the patterns are easily applicable, they might have potential as a clinical tool.

Abstract
Background:To improve quality of care for patients with hip and knee osteoarthritis (OA), a structured model for integrated OA care was developed and implemented among general practitioners (GPs) and physiotherapists (PTs) in primary care. The model was developed based on international treatment recommendations. After 6 months, patient-reported quality of care and satisfaction with care were greater, more patients were referred to physiotherapy and fewer to orthopaedic surgeon, and more patients fulfilled physical activity criteria among OA patients receiving the new model of care compared to the usual care control group1.Objectives:To assess the long-term effects 12 months after implementing the model in primary care.Methods:A cluster-randomised controlled trial with a stepped-wedge design was conducted in six Norwegian municipalities (clusters). The intervention included implementation of the model, facilitated by interactive workshops for GPs and PTs. The main components of the model were a PT led, 3 hour patient education programme followed by 8-12 weeks of individually tailored, supervised exercise. Patient participants were ≥45 years with symptomatic hip or knee OA. Primary outcome was patient-reported quality of care (OsteoArthritis Quality Indicator questionnaire; 0–100, 100 = optimal quality). Secondary outcomes included satisfaction with care, referrals to physiotherapy, orthopaedic surgeon and magnetic resonance imaging (MRI), joint replacement surgery, fulfilment of physical activity recommendations, and proportion with overweight (body mass index ≥25 kg/m2). Data was analysed using multilevel mixed models adjusted for age, sex and secular time.Results:In all, 40 of 80 GPs and 37 of 64 PTs attended the workshops. A total of 393 patients with hip and knee OA were included, with 284 in the intervention and 109 in the usual care control group. In the intervention group, 92% attended the OA education programme and 64% completed ≥8 weeks of exercise. At 12 months the intervention group reported significantly higher quality of care (score 58 vs. 41, mean difference: 17.6; 95% CI 11.1, 24.0) compared to the control group. The intervention group reported significantly higher satisfaction with care (Odds ratio (OR) 7.8; 95% CI 3.55, 17.27) and a significantly larger proportion (OR: 4.0; 95% CI 1.27, 12.63) met the recommendations for physical activity compared to the control group. A smaller proportion was referred to orthopaedic surgeon (OR 0.5; 95% CI 0.29, 1.00) and a smaller proportion received joint replacement surgery in the intervention (4%) compared to the control group (11%) (OR 0.3; 95% CI 0.14, 0.74). The proportion of patients referred to physiotherapy or MRI and the proportion with overweight were similar between the groups.Conclusion:Implementation of a structured model for OA care led to improved quality of care, higher satisfaction with care and higher physical activity levels after 12 months. These results are comparable to the 6 months results, which indicate a long-term persistence in the beneficial effects of the intervention. The lower surgical rate in the intervention compared to the control group suggests that higher uptake of OA recommendations in primary care may reduce or postpone the need for surgery in people with hip or knee OA.References:[1]Østerås N, Moseng T, Bodegom-Vos LV, et al.

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.

Abstract
BACKGROUND To improve quality of care for patients with hip and knee osteoarthritis (OA), a structured model for integrated OA care was developed based on international recommendations. The objective of this study was to assess the effectiveness of this model in primary care. METHODS AND FINDINGS We conducted a cluster-randomised controlled trial with stepped-wedge cohort design in 6 Norwegian municipalities (clusters) between January 2015 and October 2017. The randomised order was concealed to the clusters until the time of crossover from the control to the intervention phase. The intervention was implementation of the SAMBA model, facilitated by interactive workshops for general practitioners and physiotherapists with an update on OA treatment recommendations. Patients in the intervention group attended a physiotherapist-led OA education and individually tailored exercise programme for 8-12 weeks. The primary outcome was patient-reported quality of care (OsteoArthritis Quality Indicator questionnaire; 0-100, 100 = optimal quality) at 6 months. Secondary outcomes included patient-reported referrals to physiotherapy, magnetic resonance imaging (MRI), and orthopaedic surgeon consultation; patients' satisfaction with care; physical activity level; and proportion of patients who were overweight or obese (body mass index ≥ 25 kg/m2). In all, 40 of 80 general practitioners (mean age [SD] 50 [12] years, 42% females) and 37 of 64 physiotherapists (mean age [SD] 42 [8] years, 65% females) participated. They identified 531 patients, of which 393 patients (mean age [SD] 64 [10] years, 71% females) with symptomatic hip or knee OA were included. Among these, 109 patients were recruited during the control periods (control group), and 284 patients were recruited during interventions periods (intervention group). The patients in the intervention group reported significantly higher quality of care (score of 60 versus 41, mean difference 18.9; 95% CI 12.7, 25.1; p < 0.001) and higher satisfaction with OA care (odds ratio [OR] 12.1; 95% CI 6.44, 22.72; p < 0.001) compared to patients in the control group. The increase in quality of care was close to, but below, the pre-specified minimal important change. In the intervention group, a higher proportion was referred to physiotherapy (OR 2.5; 95% CI 1.08, 5.73; p = 0.03), a higher proportion fulfilled physical activity recommendations (OR 9.3; 95% CI 2.87, 30.37; p < 0.001), and a lower proportion was referred to an orthopaedic surgeon (OR 0.3; 95% CI 0.08, 0.80; p = 0.02), as compared to the control group. There were no significant group differences regarding referral to MRI (OR 0.6; 95% CI 0.13, 2.38; p = 0.42) and proportion of patients who were overweight or obese (OR 1.3; 95% CI 0.70, 2.51; p = 0.34). Study limitations include the imbalance in patient group size, which may have been due to an increased attention to OA patients among the health professionals during the intervention phase, and a potential recruitment bias as the patient participants were identified by their health professionals. CONCLUSIONS In this study, a structured model in primary care resulted in higher quality of OA care as compared to usual care. Future studies should explore ways to implement the structured model for integrated OA care on a larger scale. TRIAL REGISTRATION ClinicalTrials.gov NCT02333656.

Abstract
OBJECTIVE It is currently unknown whether osteoarthritis (OA) is inherited mainly from the mother, father, or both. This study was undertaken to explore the effect of maternal and paternal factors on hip, knee, and hand OA in offspring. METHODS Participants from the Musculoskeletal Pain in Ullensaker Study (MUST) (69% female; mean ± SD age 64 ± 9 years) and a Norwegian OA twin study (Nor-Twin) (56% female; 49 ± 11 years) reported whether their mother and/or father had OA. Using a recurrence risk estimation approach, we calculated whether maternal and paternal OA increased the risk of 1) surgically defined hip and knee OA (i.e., total joint replacement) and 2) clinically defined hip, knee, and hand OA (i.e., the American College of Rheumatology criteria) using logistic regression. Relative risks (RRs) with 95% confidence intervals (95% CIs) were calculated. RESULTS Maternal OA consistently increased the risk of offspring OA across different OA locations and severities. Having a mother with OA increased the risk of any OA in daughters (RR 1.13 [95% CI 1.02-1.25] in the MUST cohort; RR 1.44 [95% CI 1.05-1.97] in the Nor-Twin cohort) but not (or with less certainty) in sons (RR 1.16 [95% CI 0.95-1.43] in the MUST cohort; RR 1.31 [95% CI 0.71-2.41] in the Nor-Twin cohort). Having a father with OA was less likely to increase the risk of any OA in daughters (RR 1.00 [95% CI 0.85-1.16] in the MUST cohort; RR 1.52 [95% CI 0.94-2.46] in the Nor-Twin cohort) and sons (RR 1.08 [95% CI 0.83-1.41] in the MUST cohort; RR 0.93 [95% CI 0.35-2.48] in the Nor-Twin cohort). CONCLUSION OA in the mother increased the risk of surgically and clinically defined hip, knee, and hand OA in offspring, particularly in daughters. Our findings imply that heredity of OA may be linked to maternal genes and/or maternal-specific factors such as the fetal environment.

Abstract
Background Lateral epicondylitis or tennis elbow is a frequent condition with long-lasting symptoms. In order to identify predictors for treatment success and pain in lateral epicondylitis, we used data from a randomized controlled trial. This trial investigated the efficacy of physiotherapy alone or combined with corticosteroid injection for acute lateral epicondylitis in general practice. Methods The outcomes treatment success and pain score on VAS were assessed at 6, 12, 26 and 52 weeks. We ran a univariate binary logistic regression with generalized estimating equations (GEE) and subsequently an adjusted multilevel logistic regression to analyze the association between potential prognostic indicators and the outcome success/ no success. To assess the changes in pain score we used a two-level multilevel linear regression (MLR) followed by an adjusted MLR model with random effects. Results The most consistent predictor for reduced treatment success at all time points was a high Pain Free Function Index score signifying more pain on everyday activities. Being on paid sick-leave and having a recurring complaint increased short term treatment success but gave decreased long-term treatment success. The patients reporting symptoms after engaging in probable overuse in an unusual activity, tended towards increased treatment success at all time-points, but significant only at 12 weeks. The most consistent predictor of increased pain at all time points was a higher overall complaints score at baseline. Conclusions: Our results suggest that in treating acute lateral epicondylitis, a consideration of baseline pain, a registration of the patient’s overall complaint on a VAS scale and an assessment of the patient’s perceived performance in everyday activities with the Pain Free Function Index can be useful in identifying patients that will have a more protracted and serious condition.

Abstract
When the patient applies for disability benefit in Norway, the general practitioner (GP) is required by the National Insurance Administration (NAV) to confirm that the patient is unfit for work due to disease. Considering the important social role of medical certificates, they have been given surprisingly little attention by the medical critique. They may make essential differences to peoples' lives, legitimise large social costs and, in addition, the GPs report that issuing certificates can be problematic. This article explores values, attitudes and persuasive language in a selection of medical certificates written by GPs. We direct attention to such texts as significant social actors using a mixed rhetoric including certain values and attitudes. When arguing for granting the patient disability benefit, some GPs emphasised the 'worthiness' of the patient by pointing to positive attitudes approved by the national insurance: a will to work and participate, to cooperate and be motivated. Others pointed out the patient's positive character in terms of universally accepted values, called for the reader's (the NAV official) sympathy , understanding and helpfulness or appealed to his/her willingness to be realistic and pragmatic and grant disability benefit (DB). The dialogic style varied: some certifiers-although they argued for disability benefit-showed openness to possible opposing or alternative voices by displaying their own uncertainty. Others addressed the reader to share responsibility, demanding or urging for DB. This shifting rhetoric, we believe, mirrors that the GPs see themselves as the patient's advocate, and that they may find themselves conflicted. We propose further studies within qualitative research to investigate the effect of this rhetoric on the reader, the decision-makers. In addition, to improve the quality and accuracy of these important documents, we suggest that medical schools introduce students to the making of text as a specific skill of medical practice.

Abstract
AIMS To the best of our knowledge, there are no systematic reviews or meta-analyses that compare rasagiline, selegiline and safinamide. Therefore, we aimed to perform a drug class review comparing all available monoamine oxidase type B (MAO-B) inhibitors in a multiple treatment comparison. METHODS We performed a systematic literature search to identify randomized controlled trials assessing the efficacy of MAO-B inhibitors in patients with Parkinson's disease. MAO-B inhibitors were evaluated either as monotherapy or in combination with levodopa or dopamine agonists. Endpoints of interest were change in the Unified Parkinson's Disease Rating Scale (UPDRS) score and serious adverse events. We estimated the relative effect of each MAO-B inhibitor versus the comparator drug by creating three networks of direct and indirect comparisons. For each of the networks, we considered a joint model. RESULTS The systematic literature search and study selection process identified 27 publications eligible for our three network analyses. We found the relative effects of rasagiline, safinamide and selegiline treatment given alone and compared to placebo in a model without explanatory variables to be 1.560 (1.409, 1.734), 1.449 (0.873, 2.413) and 1.532 (1.337, 1.757) respectively. We also found all MAO-B inhibitors to be efficient when given together with levodopa. When ranking the MAO-B inhibitors given in combination with levodopa, selegiline was the most effective and rasagiline was the second best. CONCLUSIONS All of the included MAO-B inhibitors were effective compared to placebo when given as monotherapy. Combination therapy with MAO-B inhibitors and levodopa showed that all three MAO-B inhibitors were effective compared to placebo, but selegiline was the most effective drug.

Abstract
Background Medical certificates influence the distribution of economic benefits in welfare states; however, the qualitative aspects of these texts remain largely unexplored. The present study is the first systematic investigation done of these texts. Our aim was to investigate how GPs select and mediate information about their patients’ health and how they support their conclusions about illness, functioning and fitness for work in medical certificates. Methods We performed a textual analysis of thirty-three medical certificates produced by general practitioners (GP) in Norway at the request of the Norwegian Labour and Welfare Administration (NAV).The certificates were subjected to critical reading using the combined analytic methods of narratology and linguistics. Results Some of the medical information was unclear, ambiguous, and possibly misleading. Evaluations of functioning related to illness were scarce or absent, regardless of diagnosis, and, hence, the basis of working incapacity was unclear. Voices in the text frequently conflated, obscuring the source of speaker. In some documents, the expert’s subtle use of language implied doubts about the claimant’s credibility, but explicit advocacy also occurred. GPs show little insight into their patients’ working lives, but rather than express uncertainty and incompetence, they may resort to making too absolute and too general statements about patients’ working capacity, and fail to report thorough assessments. Conclusions A number of the texts in our material may not function as sufficient or reliable sources for making decisions regarding social benefits. Certificates as these may be deficient for several reasons, and textual incompetence may be one of them. Physicians in Norway receive no systematic training in professional writing. High-quality medical certificates, we believe, might be economical in the long term: it might increase the efficiency with which NAV processes cases and save costs by eliminating the need for unnecessary and expensive specialist reports. Moreover, correct and coherent medical certificates can strengthen legal protection for claimants. Eventually, reducing advocacy in these documents may contribute to a fairer evaluation of whether claimants are eligible for disability benefits or not. Therefore, we believe that professional writing skills should be validated as an important part of medical practice and should be integrated in medical schools and in further education as a discipline in its own right, preferably involving humanities professors.

Abstract
OBJECTIVE To explore reasons for attending a general emergency outpatient clinic versus a regular general practitioner (RGP). DESIGN Cross-sectional study using a multilingual anonymous questionnaire. SETTING Native and immigrant walk-in patients attending a general emergency outpatient clinic in Oslo (Monday-Friday, 08:00-23:00) during 2 weeks in September 2009. SUBJECTS We included 1022 walk-in patients: 565 native Norwegians (55%) and 457 immigrants (45%). MAIN OUTCOME MEASURES Patients' reasons for attending an emergency outpatient clinic versus their RGP. RESULTS Among patients reporting an RGP affiliation, 49% tried to contact their RGP before this emergency encounter: 44% of native Norwegian and 58% of immigrant respondents. Immigrants from Africa [odds ratio (OR) = 2.55 (95% confidence interval [CI]: 1.46-4.46)] and Asia [OR = 2.32 (95% CI: 1.42-3.78)] were more likely to contact their RGP before attending the general emergency outpatient clinic compared with native Norwegians. The most frequent reason for attending the emergency clinic was difficulty making an immediate appointment with their RGP. A frequent reason for not contacting an RGP was lack of access: 21% of the native Norwegians versus 4% of the immigrants claimed their RGP was in another district/municipality, and 31% of the immigrants reported a lack of affiliation with the RGP scheme. CONCLUSIONS AND IMPLICATIONS Access to primary care provided by an RGP affects patients' use of emergency health care services. To facilitate continuity of health care, policymakers should emphasize initiatives to improve access to primary health care services. KEY POINTS Access to immediate primary health care provided by a regular general practitioner (RGP) can reduce patients' use of emergency health care services. The main reason for attending a general emergency outpatient clinic was difficulty obtaining an immediate appointment with an RGP. A frequent reason for native Norwegians attending a general emergency outpatient clinic during the daytime is having an RGP outside Oslo. Lack of affiliation with the RGP scheme is a frequent reason for attending a general emergency outpatient clinic among immigrants.

Abstract
OBJECTIVES To explore whether smoking and alcohol use are associated with hand osteoarthritis (OA) features in two different OA cohorts. METHOD We studied 530 people with radiographic hand OA from the Musculoskeletal pain in Ullensaker STudy (MUST) and 187 people from the Oslo hand OA cohort [mean (sd) age 65 (8.0) and 62 (5.7) years, 71% and 91% women, respectively]. Smoking, alcohol use and hand pain were self-reported. Participants underwent conventional hand radiographs and ultrasound examination of 30 hand joints. The Kellgren-Lawrence sum score for radiographic OA severity (0-120 scale) and the proportion of participants having at least one joint with grey-scale synovitis (grade ≥1) were calculated. We studied whether smoking and alcohol use were cross-sectionally associated with radiographic OA, synovitis, and pain using adjusted linear and logistic regression analyses. RESULTS Smoking was associated with less radiographic OA in both cohorts [β = -4.71, 95% confidence interval (CI) -8.36 to -1.06 for current smoking in MUST and β = -0.15, 95% CI -0.29 to -0.02 for smoking pack-years in the Oslo hand OA cohort]. Stratified analyses indicated that the association was present in men only. Being a monthly drinker (examined in MUST only) was significantly associated with present synovitis compared to never drinkers (odds ratio = 2.35, 95% CI 1.27 to 4.34) (no gender differences). Neither smoking nor alcohol was associated with hand pain. CONCLUSIONS Smoking was associated with less radiographic hand OA whereas alcohol consumption was associated with present joint inflammation in hand OA. Future longitudinal studies are needed to explore the causal associations and explanatory mechanisms behind gender differences.

Abstract
OBJECTIVES The purpose of this study was to explore the associations between pain-related fear, pain disability, and self-perceived recovery among patients with sciatica and disk herniation followed up for 2 years. PATIENTS AND METHODS Pain-related fear was measured by the Tampa Scale for Kinesiophobia (TSK) and the Fear-Avoidance Beliefs Questionnaire-Physical Activity (FABQ-PA) subscale. Disability was measured by the Maine-Seattle Back Questionnaire. At 2 years, patients reported their sciatica/back problem on a global change scale ranging from completely gone to much worse. No specific interventions regarding pain-related fear were provided. RESULTS Complete data were obtained for 372 patients. During follow-up, most patients improved. In those who at 2 years were fully recovered (n=66), pain-related fear decreased substantially. In those who did not improve (n=50), pain-related fear remained high. Baseline levels of pain-related fear did not differ significantly between those who were fully recovered and the rest of the cohort. In the total cohort, the correlation coefficients between the 0-2-year change in disability and the changes in the TSK and the FABQ-PA were 0.33 and 0.38, respectively. In the adjusted regression models, the 0-2-year change in pain-related disability explained 15% of the variance in the change in both questionnaires. CONCLUSION Pain-related fear decreased substantially in patients who recovered from sciatica and remained high in those who did not improve. Generally, the TSK and the FABQ-PA yielded similar results. To our knowledge, this is the first study that has assessed pain-related fear in patients who recover from sciatica.

Abstract
We analysed a set of medical certificates to investigate how GPs portray patients who seek disability benefits in Norway, focusing on patient centredness, agency and involvement. We performed a qualitative linguistic analysis of 33 medical certificates collected throughout Norway that were strategically selected based on the patients' sex, age and diagnosis. We found that patients were represented as passive carriers of symptoms, in whom agency was low, failed, conditional or non-existing, or as passive objects of the actions of impersonalised others. Conversely, symptoms were foregrounded as independent and powerful actors. The patient's experience of illness was sometimes reported, but the perspective of the GP tended to be doctor oriented, rather than patient centred. The policy of the social services, which emphasises patient involvement, patient centredness and work, rather than social benefits, was almost completely absent from these medical certificates. If medical certificates are to be a valid basis for decisions within the social services, we suggest that doctor paternalism in these documents must give way to considering the patient as an involved and co-responsible individual in the processes of disability assessment.

Abstract
In this paper we consider the GI/M/1 queueing model with infinite waiting-room capacity. The customer arriving at t = 0 will find k — 1 customers waiting. The latter customers belong to a second priority class, whereas the ones arriving in [0,∞) belong to a first priority class and have the higher priority. Within each class we have a first-in-first-out queueing discipline. A customer, once at the service-point, remains there until his service is completed. Then the next customer for service is the one of highest priority among those queueing.For this model we derive the transient waiting times for customers belonging to both priority classes. The results are of special interest in appointment systems where customers may not turn up.

Abstract
Background Emergency room (ER) use is increasing in several countries. Variability in the proportion of non-urgent ER visits was found to range from 5 to 90 % (median 32 %). Non-urgent emergency visits are considered an inappropriate and inefficient use of the health-care system because they may lead to higher expenses, crowding, treatment delays, and loss of continuity of health care provided by a general practitioner. Urgency levels of doctor–walk-in patient encounters were assessed based on their region of origin in a diverse Norwegian population. Methods An anonymous, multilingual questionnaire was distributed to all walk-in patients at a general emergency outpatient clinic in Oslo during two weeks in September 2009. We analysed demographic data, patient–doctor assessments of the level of urgency, and the results of the consultation. We used descriptive statistics to obtain frequencies with 95 % confidence interval (CI) for assessed levels of urgency and outcomes. Concordance between the patients’ and doctors’ assessments was analysed using a Kendall tau-b test. We used binary logistic regression modelling to quantify associations of explanatory variables and outcomes according to urgency level assessments. Results The analysis included 1821 walk-in patients. Twenty-four per cent of the patients considered their emergency consultation to be non-urgent, while the doctors considered 64 % of encounters to be non-urgent. The concordance between the assessments by the patient and by their doctor was positive but low, with a Kendall tau-b coefficient of 0.202 (p < 0.001). Adjusted logistic regression analysis showed that patients from Eastern Europe (odds ratio (OR) = 3.04; 95 % CI 1.60–5.78), Asia and Turkey (OR = 4.08; 95 % CI 2.43–6.84), and Africa (OR = 8.47; 95 % CI 3.87–18.5) reported significantly higher urgency levels compared with Norwegians. The doctors reported no significant difference in assessment of urgency based on the patient’s region of origin, except for Africans (OR = 0.64; 95 % CI 0.43–0.96). Conclusion This study reveals discrepancies between assessments by walk-in patients and doctors of the urgency level of their encounters at a general emergency clinic. The patients’ self-assessed perception of the urgency level was related to their region of origin.

Abstract
In this paper we arrive at a series of bounds for the availability and unavailability in the time interval I = [tA, tB] ⊂ [0, ∞), for a coherent system of maintained, interdependent components. These generalize the minimal cut lower bound for the availability in [0, t] given in Esary and Proschan (1970) and also most bounds for the reliability at time t given in Bodin (1970) and Barlow and Proschan (1975). In the latter special case also some new improved bounds are given. The bounds arrived at are of great interest when trying to predict the performance process of the system. In particular, Lewis et al. (1978) have revealed the great need for adequate tools to treat the dependence between the random variables of interest when considering the safety of nuclear reactors.Satyanarayana and Prabhakar (1978) give a rapid algorithm for computing exact system reliability at time t. This can also be used in cases where some simpler assumptions on the dependence between the components are made. It seems, however, impossible to extend their approach to obtain exact results for the cases treated in the present paper.

Abstract
One inherent weakness of traditional reliability theory is that the system and the components are always described just as functioning or failed. However, recent papers by Barlow and Wu (1978) and El-Neweihi et al. (1978) have made significant contributions to start building up a theory for a multistate system of multistate components. Here the states represent successive levels of performance ranging from a perfect functioning level down to a complete failure level. In the present paper we will give two suggestions of how to define a multistate coherent system. The first one is more general than the one introduced in the latter paper, the results of which are, however, extendable. (This is also true for a somewhat more general model than ours, treated in independent work by Griffith (1980).) Furthermore, some new definitions and results are given (which trivially extend to the latter model). Our second model is similarly more general than the one introduced in Barlow and Wu (1978), the results of which are again extendable. In fact we believe that most of the theory for the traditional binary coherent system can be extended to our second suggestion of a multistate coherent system.

Abstract
BACKGROUND Widespread musculoskeletal pain (WSP) and obesity frequently co-occur and may have shared risk factors. We aimed to investigate whether four dichotomized risk factors individually or jointly increase the risk for the onset of WSP and onset of obesity. METHODS Persons aged 34-76 years in 2004 living in Ullensaker municipality, Norway, responded to questionnaires in 2004 and 2010 (n = 1553). Using causal interaction analyses, we examined whether baseline obesity and WSP, poor sleep quality, mental distress and poor physical fitness jointly increased the risk of new onset WSP (≥3 pain sites leading to disability the last year) and new onset obesity (self-reported BMI ≥30 kg/m(2) ) in persons without WSP (n = 1270) or without obesity (n = 1300) at baseline respectively. RESULTS The mean (SD) age was 51 (12.1) years and 56% were female. The incidence of WSP and obesity were 9.1% and 5.4%. Mental distress and poor sleep quality individually and jointly with poor physical fitness increased WSP onset risk (relative excess risk due to interaction [RERI] = 1.90, 95% CI, 0.39-3.42 and RERI = 1.43, 95% CI, 0.10-2.76). Poor physical fitness individually increased the risk for new onset obesity, and baseline WSP and poor sleep quality jointly (RERI = 1.87, 95% CI, 0.49-3.24). The presence of more risk factors was dose-dependently associated with onset WSP and to a lesser extent with onset obesity. CONCLUSION The onset of WSP and the onset of obesity were results of joint effects of exposures. Poor physical fitness was a key covariate in increasing the risk for both conditions. WHAT DOES THIS STUDY ADD?: In a general population, the new onset of widespread pain and new onset of obesity were results of joint effects of risk factors and particularly poor physical fitness. The study may aid in the identification of patients at risk of future disability.

Abstract
BACKGROUND Previous research indicates that people with osteoarthritis (OA) are not receiving the recommended and optimal treatment. Based on international treatment recommendations for hip and knee OA and previous research, the SAMBA model for integrated OA care in Norwegian primary health care has been developed. The model includes physiotherapist (PT) led patient OA education sessions and an exercise programme lasting 8-12 weeks. This study aims to assess the effectiveness, feasibility, and costs of a tailored strategy to implement the SAMBA model. METHODS/DESIGN A cluster randomized controlled trial with stepped wedge design including an effect, process, and cost evaluation will be conducted in six municipalities (clusters) in Norway. The municipalities will be randomized for time of crossover from current usual care to the implementation of the SAMBA model by a tailored strategy. The tailored strategy includes interactive workshops for general practitioners (GPs) and PTs in primary care covering the SAMBA model for integrated OA care, educational material, educational outreach visits, feedback, and reminder material. Outcomes will be measured at the patient, GP, and PT levels using self-report, semi-structured interviews, and register based data. The primary outcome measure is patient-reported quality of care (OsteoArthritis Quality Indicator questionnaire) at 6-month follow-up. Secondary outcomes include referrals to PT, imaging, and referrals to the orthopaedic surgeon as well as participants' treatment satisfaction, symptoms, physical activity level, body weight, and self-reported and measured lower limb function. The actual exposure to the tailor made implementation strategy and user experiences will be measured in a process evaluation. In the economic evaluation, the difference in costs of usual OA care and the SAMBA model for integrated OA care will be compared with the difference in health outcomes and reported by the incremental cost-effectiveness ratio (ICER). DISCUSSION The results from the present study will add to the current knowledge on tailored strategies, which aims to improve the uptake of evidence-based OA care recommendations and improve the quality of OA care in primary health care. The new knowledge can be used in national and international initiatives designed to improve the quality of OA care. TRIAL REGISTRATION ClinicalTrials.gov NCT02333656.

Abstract
OBJECTIVE Most pain in patients aged ≥50 years affects multiple sites and yet the predominant mode of presentation is single-site syndromes. The aim of this study was to investigate if pain sites form clusters in this population and if any such clusters are associated with health factors other than pain. SETTING Six general practices in North Staffordshire, UK. DESIGN Cross-sectional, postal questionnaire, study. PARTICIPANTS Community-dwelling adults aged ≥50 years registered at the general practices. MAIN OUTCOMES MEASURES Number of pain sites was measured by asking participants to shade sites of pain lasting ≥1 day in the past 4 weeks on a blank body manikin. Health factors measured included anxiety and depression (Hospital and Anxiety Depression Scale), cognitive complaint (Sickness Impact Profile) and sleep. Pain site clustering was investigated using latent class analysis. Association of clusters with health factors, adjusted for age, sex, body mass index and morbidities, was analysed using multinomial regression models. RESULTS 13 986 participants (adjusted response 70.6%) completed a questionnaire, of whom 12 408 provided complete pain data. Four clusters of participants were identified: (1) low number of pain sites (36.6%), (2) medium number of sites with no back pain (31.5%), (3) medium number of sites with back pain (17.9%) and (4) high number of sites (14.1%). Compared to Cluster 1, other clusters were associated with poor health. The strongest associations (relative risk ratios, 95% CI) were with Cluster 4: depression (per unit change in score) 1.11 (1.08 to 1.14); cognitive complaint 2.60 (2.09 to 3.24); non-restorative sleep 4.60 (3.50 to 6.05). CONCLUSIONS These results indicate that in a general population aged ≥50 years, pain forms four clusters shaped by two dimensions-number of pain sites (low, medium, high) and, within the medium cluster, the absence or presence of back pain. The usefulness of primary care treatment approaches based on this simple classification should be investigated.

Abstract
BACKGROUND The Oslo Accident and Emergency Outpatient Clinic (OAEOC) experienced a 5-6% annual increase in patient visits between 2005 and 2011, which was significantly higher than the 2-3% annual increase among registered Oslo residents. This study explored immigrant walk-in patients' use of both the general emergency and trauma clinics of the OAEOC and their concomitant use of regular general practitioners (RGPs) in Oslo. METHODS A cross-sectional survey of walk-in patients attending the OAEOC during 2 weeks in September 2009. We analysed demographic data, patients' self-reported affiliation with the RGP scheme, self-reported number of OAEOC and RGP consultations during the preceding 12 months. The first approach used Poisson regression models to study visit frequency. The second approach compared the proportions of first- and second-generation immigrants and those from the four most frequently represented countries (Sweden, Pakistan, Somalia and Poland) among the patient population, with their respective proportions within the general Oslo population. RESULTS The analysis included 3864 patients: 1821 attended the Department of Emergency General Practice ("general emergency clinic"); 2043 attended the Section for Orthopaedic Emergency ("trauma clinic"). Both first- and second-generation immigrants reported a significantly higher OAEOC visit frequency compared with Norwegians. Norwegians, representing 73% of the city population accounted for 65% of OAEOC visits. In contrast, first- and second-generation immigrants made up 27% of the city population but accounted for 35% of OAEOC visits. This proportional increase in use was primarily observed in the general emergency clinic (42% of visits). Their proportional use of the trauma clinic (29%) was similar to their proportion in the city. Among first-generation immigrants only 71% were affiliated with the RGP system, in contrast to 96% of Norwegians. Similar finding were obtained when immigrants were grouped by nationality. Compared to Norwegians, immigrants from Sweden, Pakistan and Somalia reported using the OAEOC significantly more often. Immigrants from Sweden, Poland and Somalia were over-represented at both clinics. The least frequent RGP affiliation was among immigrants from Sweden (32%) and Poland (65%). CONCLUSIONS In Norway, immigrant subgroups use emergency health care services in different ways. Understanding these patterns of health-seeking behaviour may be important when designing emergency health services.

Abstract
OBJECTIVE To explore factors related to hand pain in persons with radiographic hand osteoarthritis (OA). METHODS Persons in the Musculoskeletal Pain in Ullensaker Study with radiographic hand OA (≥1 joint with Kellgren/Lawrence grade ≥2) were included (n = 530). We examined the cross-sectional association between possible explanatory variables and hand pain in the entire sample and in 2 hand OA phenotypes (erosive versus nonerosive) using structural equation analyses. Outcome variables were the Australian/Canadian Hand Osteoarthritis Index (AUSCAN; range 0-20) and number of tender finger joints upon palpation (NTJ; range 0-30). RESULTS The mean age was 65 years (40-79 years) and 375 participants were women (71%). Diabetes mellitus, female sex, lower education status, familial OA, infrequent alcohol drinking, widespread pain, poor mental health, and higher number of finger joints with ultrasound-detected synovitis and radiographic OA were related to more hand pain in the entire sample. Stratified analyses showed that diabetes mellitus was strongly associated with AUSCAN pain (B-unstandardized coefficient = 3.81 [95% confidence interval (95% CI) 2.27, 5.35]) and NTJ (B-unstandardized coefficient = 4.16 [95% CI 2.01, 6.31]) in erosive hand OA only. In nonerosive OA, lower education status, having familial OA, and poor mental health were associated with hand OA pain. Widespread pain was associated with both outcomes in both phenotypes. CONCLUSION Structural and inflammatory OA changes as well as demographic factors, psychosocial factors, and diabetes mellitus were associated with pain in hand OA. The strong association between diabetes mellitus and pain in erosive hand OA should be further explored.

Abstract
BACKGROUND Population studies have reported that shoulder pain is the third most frequently reported musculoskeletal pain. Long duration, pain intensity and high level of disability predict persistent complaints. The present study aimed to describe the prevalence of shoulder pain in a general population and follow this over a long period (1990 to 2004). The objective was also to describe the stability of shoulder pain and patterns of co-occurrence with neck and upper back pain. METHODS Data were obtained from a self-reported questionnaire in a population in Ullensaker muncipality, north-east of Oslo. The Standard Nordic Questionnaire was sent in 1990, 1994 and 2004 to inhabitants belonging to six birth cohorts from 1918-20 to 1968-70. RESULTS The 1-year prevalence of shoulder pain was 46.7% (95% CI, 44.9% to 48.6%) in 1990, 48.7% (95% CI, 46.8% to 50.5%) in 1994, and 55.2% (95% CI, 53.5% to 56.9%) in 2004. Approximately three-quarters of the persons with shoulder pain at one given time also reported shoulder pain at the next follow-up. CONCLUSIONS Prevalence of shoulder pain during a 14-year period was high and slightly increasing. Shoulder pain was reported most frequently in co-occurrence with neck pain. Classification models should include neck pain as well as other co-occurring pain sites.

Abstract
Background Obesity is a well-known risk factor for osteoarthritis (OA). The majority of obesity research in OA is performed using self-reported BMI-data, however, its validity in persons with OA is unknown. The aim of this study was to compare the validity of self-reported body mass index (BMI) in persons with and without clinical osteoarthritis (OA) in a population-based survey. Methods Height and weight were self-reported, and thereafter measured in 600 persons with and without clinical OA according to the American College of Rheumatology-criteria (knees, hips and/or hands). We compared the differences between measured and self-reported heights, weights and BMIs (kg/m2) for the two groups and explored whether demographic/clinical factors were associated with inaccurate reporting in the OA patients using multivariate linear regression analyses. Results Mean (SD) age was 64 (8.7) years and 412 (69%) were women. Participants with clinical OA (n = 449) underreported their BMI to a greater extent than participants without clinical OA (n = 151) [mean (SD) difference 1.34 (1.68) kg/m2 and 0.78 (1.40) kg/m2 (p = 0.000), respectively]. There was a strong dose-dependent association between higher measured BMI and greater underreporting of BMI in multivariate analyses (BMI 25–29.99 kg/m2: B = 0.40, 95% CI, 0.06, 0.77), BMI ≥ 30 kg/m2: B = 1.30, 95% CI, 0.86, 1.75) in the clinical OA patients. A higher age as well as the time interval from self-reported to measured BMI-data were associated with inaccurate reporting. Conclusions Researchers using self-reported height and weight data should be aware of limited agreement with actual height and weight in overweight and obese individuals with clinical OA.

Abstract
Immigrants from South Asia, the Middle East, and Africa living in Northern Europe frequently have low vitamin D levels and more pain compared to the native Western population. The aim of this study was to examine whether daily vitamin D3 (25 μg/d or 10 μg/d) supplementation for 16 weeks would improve musculoskeletal pain or headache compared to placebo. This randomized, double-blind, placebo-controlled, parallel-group trial recruited 251 participants aged 18 to 50 years, and 215 (86%) attended the follow-up visit. The pain measures were occurrence, anatomical localization, and degree of musculoskeletal pain, as measured by visual analogue scale (VAS) score during the past 2 weeks. Headache was measured with VAS and the Headache Impact Test (HIT-6) questionnaire. At baseline, females reported more pain sites (4.7) than males (3.4), and only 7% reported no pain in the past 2 weeks. During the past 4 weeks, 63% reported headache with a high mean HIT-6 score of 60 (SD 7). At follow-up, vitamin D level, measured as serum 25(OH)D3, increased from 27 nmol/L to 52 nmol/L and from 27 nmol/L to 43 nmol/L in the 25-μg and 10-μg supplementation groups, respectively, whereas serum 25(OH)D3 did not change in the placebo group. Pain scores and headache scores were improved at follow-up compared with baseline. The use of vitamin D supplements, however, showed no significant effect on the occurrence, anatomical localization, and degree of pain or headache compared to placebo.

Abstract
BACKGROUND Patients frequently present with multiple and 'unexplained' symptoms, often resulting in complex consultations. To better understand these patients is a challenge to health care professionals, in general, and GPs, in particular. OBJECTIVES In our research on symptom reporting, we wanted to explore whether patients consider that they may suffer from conditions commonly regarded as unexplained, and we explored associations between these concerns and symptom load, life stressors and socio-demographic factors. METHODS Consecutive, unselected patients in general practice completed questionnaires addressing eight conditions commonly regarded as unexplained (amalgam poisoning, Candida syndrome, fibromyalgia, food intolerance, electromagnetic hypersensitivity, burnout syndrome, chronic fatigue syndrome and irritable bowel syndrome). With logistic regression, we analysed associations with symptom load, burden of life stressors with negative impact on present health and socio-demographic variables. RESULTS Out of the 909 respondents (response rate = 88.8%), 863 had complete data. In total, 39.6% of patients had considered that they may suffer from one or more unexplained conditions (UCs). These concerns were strongly and positively associated with recent symptom load and number of life stressors. If we excluded burnout and food intolerance, corresponding associations were found. CONCLUSION Patients frequently considered that they may suffer from UCs. The likelihood of such concerns strongly increased with an increasing symptom load and with the number of life stressors with negative impact on present health. Hence, the number of symptoms may be a strong indicator of whether patients consider their symptoms part of such often controversial multisymptom conditions.

Abstract
BACKGROUND Shoulder pain is common in the general population. Reports on specific diagnoses in general populations are scarce and only from primary care. The diagnostic distribution of shoulder disorders in secondary care is not reported. Most of the clinical research in the shoulder field is done in hospital settings. The aim of this study was to identify the diagnoses in a 1-year cohort in a hospital-based outpatient clinic using standardized diagnostic criteria and to compare the results with previous studies. METHODS A diagnostic routine was conducted among patients referred to our physical medicine outpatient clinic at Oslo University Hospital. Diagnostic criteria were derived from the literature and supplemented with research criteria. RESULTS Of 766 patients diagnosed, 55% were women and the mean age was 49 years (range 19-93, SD ± 14). The most common diagnoses were subacromial pain (36%), myalgia (17%) and adhesive capsulitis (11%). Subacromial pain and adhesive capsulitis were most frequent in persons aged 40-60 years. Shoulder myalgia was most frequent in age groups under 40. Labral tears and instability problems (8%) were most frequent in young patients and not present after age 50. Full-thickness rotator cuff tears (8%) and glenohumeral osteoarthritis (4%) were more prevalent after the age of 60. Few differences were observed between sexes. We identified three studies reporting shoulder diagnoses in primary care. CONCLUSION Subacromial pain syndrome, myalgia and adhesive capsulitis were the most prevalent diagnoses in our study. However, large differences in prevalence between different studies were found, most likely arising from different use of diagnostic criteria and a difference in populations between primary and secondary care. Of the diagnoses in our cohort, 20% were not reported by the studies from primary care (glenohumeral osteoarthritis, full thickness rotator cuff tears, labral tears and instabilities).

Abstract
OBJECTIVES To investigate the longitudinal validity of patients' ratings of global perceived change (GPC) and to assess the implications of using the GPC as the anchor to determine the minimal important change (MIC). STUDY DESIGN AND SETTING Secondary analysis of data from a multicenter study including 380 patients with disc-related sciatica with follow-ups at 3, 6, 12, and 24 months. The GPC scale ranged from much worse to completely gone. Five patient-reported outcome measures were used. An MIC was defined as the mean change score in the actual outcome measure for patients reporting being better. The influence of patients' current state and baseline scores on the GPC was analyzed by multivariate linear regression. Differences in the magnitude of the MIC between the 3- and 24-month recall periods were analyzed by hierarchical linear models. RESULTS Across all recall periods and outcome measures, the GPC was strongly influenced by the patient's state at the time of asking. In four of five outcome measures, the magnitude of the MIC increased when recall increased from 3 to 24 months. CONCLUSION Caution is needed when using the GPC to determine the MIC of patient-reported outcome measures in patients with chronic conditions.

Abstract
OBJECTIVE To develop and test a new instrument for patient self-reported quality of osteoarthritis (OA) care, and to provide quality indicator (QI) pass rates in a Norwegian OA cohort. METHODS The OsteoArthritis Quality Indicator (OA-QI) questionnaire was developed using published QIs, expert panels, and patient interviews. Self-reported data were collected from 359 persons in a Norwegian OA cohort, and test-retest reliability and validity were assessed. Separate QI pass rates and summary QI pass rates were calculated. RESULTS The 17-item questionnaire includes QIs related to patient education and information, regular provider assessments, referrals, and pharmacologic treatment. The patient self-reported questionnaire was completed with minimal respondent burden. Support for content validity was confirmed by 2 patient research partners and 2 expert panels. All 10 predefined hypotheses relating to construct validity were confirmed. Test-retest kappa coefficients ranged from 0.20-0.80 and the percentage of exact agreement ranged from 62-90%. The mean pass rate for individual QIs was 31% (range 5-49%). The median summary QI pass rate was 27% (interquartile range 12-50%), with lower summary pass rates for nonpharmacologic compared to pharmacologic treatments. CONCLUSION To our knowledge, this is the first instrument developed to measure patient-reported QI pass rates for OA care. This study indicates that the OA-QI questionnaire is acceptable to persons with OA, and its short format makes it suitable for population surveys. The low patient self-reported QI pass rates in this study suggest a potential for quality improvement in OA care.
