BackgroundAlthough interdisciplinary multimodal pain treatment (IMPT) programs are widely regarded as treatment of choice for patients with chronic pain, there are signs that many patients are unable to maintain their treatment gains in the long term. To facilitate the maintenance of positive treatment outcomes over time, we developed two relapse prevention strategies. ObjectiveThe main objective of this study was to explore the feasibility of these strategies within the context of IMPT programs. MethodsWe performed a feasibility study using 3 workbook prototypes containing either one or both strategies. For a period of 6 months, the workbooks were made available in two IMPT facilities. Qualitative data were collected through a focus group and semistructured interviews. We performed a thematic analysis using a deductive approach with (1) applicability to the treatment program, (2) acceptability of the workbook content, and (3) form, as predefined themes. ResultsThe final dataset consisted of transcripts from a focus group with health care providers and 11 telephone interviews and 2 additional in-depth interviews with patients. In general, the intervention was perceived as useful, easy to use, and in line with the treatment program. The data also include suggestions to further improve the use of both strategies, including more specific implementation guidelines, revised goal-setting procedure, and development of a mobile health version. However, several factors, including a high dropout rate and small sample size, impact the external validity of our findings. ConclusionsThis study should be regarded as a first step in the process of transforming the prototype workbook into an effective intervention for clinical practice. Although these initial results indicate a favorable evaluation of both behavior regulation strategies within the workbook, this study encountered multiple barriers regarding implementation and data collection that limit the generalizability of these results. Future research efforts should specifically address the fidelity of HCPs and patients and should include clear procedures regarding recruitment and use of both relapse prevention strategies during treatment.

BackgroundTo facilitate adherence to adaptive pain management behaviors after interdisciplinary multimodal pain treatment, we developed a mobile health app (AGRIPPA app) that contains two behavior regulation strategies. ObjectiveThe aims of this project are (1) to test the effectiveness of the AGRIPPA app on pain disability; (2) to determine the cost-effectiveness; and (3) to explore the levels of engagement and usability of app users. MethodsWe will perform a multicenter randomized controlled trial with two parallel groups. Within the 12-month inclusion period, we plan to recruit 158 adult patients with chronic pain during the initial stage of their interdisciplinary treatment program in one of the 6 participating centers. Participants will be randomly assigned to the standard treatment condition or to the enhanced treatment condition in which they will receive the AGRIPPA app. Patients will be monitored from the start of the treatment program until 12 months posttreatment. In our primary analysis, we will evaluate the difference over time of pain-related disability between the two conditions. Other outcome measures will include health-related quality of life, illness perceptions, pain self-efficacy, app system usage data, productivity loss, and health care expenses. ResultsThe study was approved by the local Medical Research Ethics Committee in October 2019. As of March 20, 2020, we have recruited 88 patients. ConclusionsThis study will be the first step in systematically evaluating the effectiveness and efficiency of the AGRIPPA app. After 3 years of development and feasibility testing, this formal evaluation will help determine to what extent the app will influence the maintenance of treatment gains over time. The outcomes of this trial will guide future decisions regarding uptake in clinical practice.

Purpose: Small fiber neuropathy (SFN) is characterized by neuropathic pain, associated with decreased quality of life (QOL). It remains unclear which psychosocial factors play a role in SFN. The experience sampling method (ESM) allows a profound understanding of the real-time fluctuations in reaction to events. The main goal of this study was to increase knowledge of the interrelationships between pain intensity, physical activity, and psychosocial factors in patients with SFN in daily practice over time. Patients and Methods: A prospective observational ESM study with the PsyMate© application (smart-eHealth GmbH, Luxembourg) was conducted at the Adelante location of Maastricht University Medical Center+ in the Netherlands. Participants with idiopathic SFN, older than 18 years, with an indication for rehabilitation, were included. Pain intensity, fatigue, positive and negative affect, physical activity, avoidance behavior, and pain catastrophic thoughts were incorporated into the ESM questions. Participants received 10 beep signals per day followed by the above-mentioned questions, for consecutive 7 days. The results were analyzed with linear mixed-effect models. Results: Twenty-one participants were included with a mean age of 48.24 (SD ± 13.89) years, of whom 76.2% were female. More pain (now) resulted in more physical activity (later) (a) and more physical activity (now) resulted in more pain (later) (b). The first association (a) is influenced by pain catastrophic thoughts and fatigue, and the second (b) by an increase in affective states and a lower level of avoidance behavior. Conclusion: In idiopathic SFN, pain intensity, and physical activity showed a 2-sided association, influenced by catastrophic thoughts, fatigue, affective states, and avoidance behavior.

Background: In chronic pain syndromes, symptoms can fluctuate and change over time. Standard questionnaires cannot register these fluctuations. Nonetheless, the experience sampling method (ESM) is developed to collect momentary measurements of everyday complaints, tracing fluctuations in symptoms and disabling factors over time. Although valuable information can be collected in this way, assessment may also be a burden. This study aimed to investigate the acceptability, usability, and feasibility of ESM in chronic secondary pain syndromes, in a single-center study in the Netherlands. Methods: A prospective observational study with repeated measurements was conducted in patients with chronic secondary neuropathic and musculoskeletal pain syndromes, including small fiber neuropathy, spinal cord injury, and rheumatoid disorder. Results: Thirty-four participants were included and filled in the ESM, of whom 19 were diagnosed with small fiber neuropathy, 11 with spinal cord injury, and 4 with a rheumatoid disorder. The mean age was 54.7 ± 13.9 years (range: 23-77) of whom 52.9% were female. In total, 19 participants filled in the general and user-friendliness evaluation about the acceptability and usability of the ESM. The general evaluation showed no influence of ESM on participants' social contacts (mean 1.47, SD 1.12), activities (mean 1.74, SD 1.44), and mood (mean 1.89, SD 1.59). The answers options of ESM were a good representation of the experiences of participants (mean 4.58, SD 1.77). Regarding feasibility, the overall response rate for answering the beep signals of ESM was 44.5% in total. The missing rate per person varied from 13% to 97% with a median of 54.1%. Conclusion: The general evaluation and the user-friendliness revealed sufficient outcomes in favor of the ESM application. ESM seems a promising measurement tool to use in secondary chronic pain syndromes. [ABSTRACT FROM AUTHOR]

Context: Psychosocial parameters play an important role in the onset and persistence of chronic musculoskeletal disorders (CMSDs). Exercise therapy is a valuable therapeutic modality as part of CMSD rehabilitation. Hereby, exercise intensity is an important factor regarding changes in pain and disability in multiple CMSDs. However, the impact of exercise intensity on psychosocial outcomes remains poorly explored. Objective: To identify the effects of different modes of exercise intensity on psychosocial outcomes in persons with CMSDs. Data Sources: A systematic search was conducted up to November 2020 using the following databases: PubMed/MEDline, PEDro, Cochrane Library, and Web of Science. Study Selection: Studies reporting exercise therapy in CMSDs with a predefined display of exercise intensity and an evaluation of at least 1 psychosocial outcome were included. Study Design: Systematic review. Level of Evidence: Level 2a. Data Extraction: Data regarding demographics, exercise intensity, and psychosocial outcomes were included in a descriptive analysis. Methodological quality was assessed using the PEDro scale and Critical Appraisal Skills Programme (CASP) checklist. Results: A total of 22 studies, involving 985 participants (with fibromyalgia, chronic low back pain, knee osteoarthritis, psoriatic arthritis, and axial spondyloarthritis) were included (mean PEDro score = 5.77/10). The most common psychosocial outcomes were quality of life (QoL) (n = 15), depression (n = 10), and anxiety (n = 9). QoL improved at any exercise intensity in persons with fibromyalgia. However, persons with fibromyalgia benefit more from exercising at low to moderate intensity regarding anxiety and depression. In contrast, persons with chronic low back pain benefit more from exercising at a higher intensity regarding QoL, anxiety, and depression. Other CMSDs only showed limited or conflicting results regarding the value of certain exercise intensities. Conclusion: Psychosocial outcomes are influenced by the intensity of exercise therapy in fibromyalgia and chronic low back pain, but effects differ across other CMSDs. Future research is necessary to determine the exercise intensity that yields optimal exercise therapy outcomes in specific CMSDs. [ABSTRACT FROM AUTHOR]

Background and aims: Integration of care is lacking for chronic musculoskeletal pain patients. Network Pain Rehabilitation Limburg, a transmural health care network, has been designed to provide integrated rehabilitation care from a biopsychosocial perspective to improve patients' levels of functioning. This feasibility study aims to provide insight into barriers and facilitators for the development, implementation, and transferability. Methods: This study was conducted with a three-phase iterative and incremental design from October 2017 to October 2018. The network comprises two rehabilitation practices, and three local primary care networks, with a general practitioner together with, a mental health practice nurse, and a physiotherapist or exercise therapist. These stakeholders with a random sample of participating patients took part in evaluations, consisting of interviews, focus groups, and observations. Field notes and observations were recorded during meetings. The Consolidated Framework for Implementation Research guided data collection and analysis. Results were used to refine the next phase. Results: According to health care professionals, guidelines and treatment protocols facilitate consistency and transparency in collaboration, biopsychosocial language, and treatment. One mentioned barrier is the stigmatization of chronic pain by the general population. In regular care, approaches are often more biomedical than biopsychosocial, causing patients to resist participating. The current organization of health care acts as a barrier, complicating implementation between and within practices. Health care professionals were enthusiastic about the iterative, bottom-up development. A critical mass of participating organizations is needed for proper implementation. Conclusion: Network Pain Rehabilitation Limburg is feasible in daily practice if barriers are overcome and facilitators of development, implementation, and transferability are promoted. These findings will be used to refine Network Pain Rehabilitation Limburg. A large-scale process and effect evaluation will be performed. Our implementation strategies and results may assist other health care organizations aspiring to implement a transmural network using a similar model.

Purpose: Literature shows promising effects for interdisciplinary biopsychosocial rehabilitation programs in patients with chronic low back pain (CLBP). Not every patient needs an interdisciplinary rehabilitation trajectory provided in a secondary care setting. Patients with moderate complex psychosocial complaints might benefit from biopsychosocial interventions offered in primary care under supervision of a physician in rehabilitation medicine (i.e. biopsychosocial integrated care intervention). This study investigated the feasibility and effectiveness of such intervention in patients with CLBP with moderate complex psychosocial complaints. Methods: mixed-method. Patients (aged 18-65 years, low back pain ≥12 weeks, moderate complex psychosocial complaints) received the intervention (4 individual sessions, 8 group sessions) provided by trained primary care physiotherapists. Physicians in rehabilitation medicine provided one consultation afterwards. Data from patients (n¼18), physicians (n¼4) and physiotherapists (n¼12) were used. Results: Physiotherapists were satisfied with the training. Patient attendance was good for individual sessions, less for groups. Physiotherapists sufficiently delivered the intervention, although recruitment and contextual factors influenced delivery. Patients reported significantly reduced functional disability (Quebec Back Pain Disability Scale) post-treatment (-8.3, 95% CI -13.3 to -2.7) and at 3months follow-up (-7.6, 95% CI -12.9 to -2.2). Conclusions: A biopsychosocial integrated intervention is feasible and potentially effective in patients with CLBP. [ABSTRACT FROM AUTHOR]

Background and objectives: Although Interdisciplinary Multimodal Pain Treatment (IMPT) programmes share a biopsychosocial approach to increase the wellbeing of patients with chronic pain, substantial variation in content and duration have been reported. In addition, it is unclear to what extent any favourable health outcomes are maintained over time. Therefore, our first aim was to identify and analyse the change over time of patient‐related outcome measures in cohorts of patients who participated in IMPT programmes. Our second aim was to acquire insight into the heterogeneity of IMPT programmes. Databases and data treatment: The study protocol was registered in Prospero under CRD42018076093. We searched Medline, Embase, PsycInfo and Cinahl from inception to May 2020. All study selection, data extraction and risk of bias assessments were independently performed by two researchers. Study cohorts were eligible if they included adult patients with chronic primary musculoskeletal pain for at least 3 months. We assessed the change over time, by calculating pre‐post, post‐follow‐up and pre‐follow‐up contrasts for seven different patient‐reported outcome domains. To explore the variability between the IMPT programmes, we summarized the patient characteristics and treatment programmes using the intervention description and replication checklist. Results: The majority of the 72 included patient cohorts significantly improved during treatment. Importantly, this improvement was generally maintained at follow‐up. In line with our expectations and with previous studies, we observed substantial methodological and statistical heterogeneity. Conclusions: This study shows that participation in an IMPT programme is associated with considerable improvements in wellbeing that are generally maintained at follow‐up. The current study also found substantial heterogeneity in dose and treatment content, which suggests different viewpoints on how to optimally design an IMPT programme. Significance: The current study provides insight into the different existing approaches regarding the dose and content of IMPT programs. This analysis contributes to an increased understanding of the various approaches by which a biopsychosocial perspective on chronic pain can be translated to treatment programs. Furthermore, despite theoretical and empirical assertions regarding the difficulty to maintain newly learned health behaviors over time, the longitudinal analysis of health outcomes did not find a relapse pattern for patients who participated in IMPT programs [ABSTRACT FROM AUTHOR]

Abstract Background Patients with chronic fatigue syndrome experience extreme fatigue, which often leads to substantial limitations of occupational, educational, social and personal activities. Currently, there is no consensus regarding the treatment. Patients try many different therapies to overcome their fatigue. Although there is no consensus, cognitive behavioural therapy is seen as one of the most effective treatments. Little is known about multidisciplinary rehabilitation treatment, a combination of cognitive behavioural therapy with principles of mindfulness, gradual increase of activities, body awareness therapy and pacing. The difference in effectiveness and cost-effectiveness between multidisciplinary rehabilitation treatment and cognitive behavioural therapy is as yet unknown. The FatiGo (Fatigue-Go) trial aims to compare the effects of both treatment approaches in outpatient rehabilitation on fatigue severity and quality of life in patients with chronic fatigue syndrome. Methods One hundred twenty patients who meet the criteria of chronic fatigue syndrome, fulfil the inclusion criteria and sign the informed consent form will be recruited. Both treatments take 6 months to complete. The outcome will be assessed at 6 and 12 months after the start of treatment. Two weeks after the start of treatment, expectancy and credibility will be measured, and patients will be asked to write down their personal goals and score their current performance on these goals on a visual analogue scale. At 6 and 14 weeks after the start of treatment, the primary outcome and three potential mediators—self-efficacy, causal attributions and present-centred attention-awareness—will be measured. Primary outcomes are fatigue severity and quality of life. Secondary outcomes are physical activity, psychological symptoms, self-efficacy, causal attributions, impact of disease on emotional and physical functioning, present-centred attention-awareness, life satisfaction, patient personal goals, self-rated improvement and economic costs. The primary analysis will be based on intention to treat, and longitudinal analysis of covariance will be used to compare treatments. Discussion The results of the trial will provide information on the effects of cognitive behavioural therapy and multidisciplinary rehabilitation treatment at 6 and 12 months follow-up, mediators of the outcome, cost-effectiveness, cost-utility, and the influence of treatment expectancy and credibility on the effectiveness of both treatments in patients with chronic fatigue syndrome.

Background: For several widely used patient-reported outcome measures (PROMs) in chronic musculoskeletal pain (CMSP) rehabilitation, it is still not known whether they are responsive to change, and what the smallest detectable change (SDC) and minimal clinically important change (MCIC) are. Knowledge of these values can be used to accurately interpret change scores in research and clinical practice.Methods: In this retrospective cohort study, the responsiveness, the SDC and the MCIC of the mental components of the Research and Development 36-Item Health Survey (RAND-36), the Pain Catastrophizing Scale (PCS) and the Tampa Scale of Kinesiophobia (TSK) were investigated in CMSP patients. Responsiveness, the SDC and MCIC were determined by using both anchor and distribution-based methods.Results: For all outcome measures, there was a progression from smallest to largest mean change scores between participants who did not perceive change and those who reported change after treatment. However, correlations of the Global Perceived Effect (GPE) with the change scores on the outcome measures were low. For all outcome measures, the SDC was larger than the MCIC.Conclusions: For this population, the questionnaires were shown not to be responsive. Furthermore, the questionnaires appeared not to be able to distinguish clinically important change from measurement error in individual patients. The finding of large measurement errors of PROMs is in line with previous research in pain rehabilitation. Using generic PROMs only, to examine changes in psychosocial status due to a pain rehabilitation programme, is therefore questionable.Significance: This study shows that widely used generic psychosocial PROMs might not be responsive and not able to distinguish clinically important change from measurement error in individual chronic musculoskeletal pain patients. It therefore seems reasonable to reconsider the (compulsory) use of these PROMs for assessing the quality of pain rehabilitation programmes, and necessary to consider other, more objective, outcome measures for this purpose in this population.

Stimulating patients to approach their pain from a biopsychosocial perspective is central to chronic pain rehabilitation. However, conversations between patients and their healthcare professionals about the social and psychological factors that may contribute to the continuation of pain and disability can be challenging. The current scientific literature does not sufficiently pinpoint the difficulties in patient–practitioner interaction on chronic pain, and it falls short of answering the question of how a joint exploration of the social and psychological factors that might be involved in the patient's pain and evolving disability can be enhanced. In this theoretical article, we introduce discursive psychology as a potentially valuable research perspective to gain a better understanding of the difficulties in patient–practitioner interaction in the context of chronic pain rehabilitation. Discursive psychology focuses on features of people's talk (e.g. that of patients and practitioners) and is concerned with the social practices that people perform as part of a specific interactional context. In this paper, we provide an introduction to the main theoretical notions of discursive psychology. We illustrate how discursive psychological analyses can inform our understanding of the specific sensitivities in conversations between patients with chronic pain and their practitioners. Finally, we address how a better understanding of these sensitivities offers a gateway towards improving these conversations. [ABSTRACT FROM AUTHOR]

Introduction Patients having chronic musculoskeletal pain (CMP) face challenges as mismatches often exist between the complexity of patient's pain problem and the rehabilitation treatment offered. This can result in less efficient care for the patient and increased medical shopping. The Network Pain Rehabilitation Limburg (NPRL), a transmural integrated healthcare network, will be designed to improve daily care for patients with CMP. NPRL focusses on improving patient's level of functioning despite pain by stimulating a biopsychosocial approach given by all involved healthcare professionals. A feasibility study will be performed which will give insight into the barriers and facilitators, perceived value, acceptability and implementation strategies for NPRL. Methods and analysis This study has a three-phase iterative and incremental design, based on key principles of a user-centred design. Mixed methods will be used in which healthcare professionals and patients involved in NPRL will participate. In phase 1, NPRL will be developed and healthcare professionals educated. Phase 2 focusses on the implementation and phase 3 on the transferability of NPRL. In addition, preliminary data on patient's work status, general health and participation level will be collected. The qualitative results of each phase will be analysed following the Consolidated Framework for Implementation Research (CFIR) and will be used to refine NPRL in daily practise. Ethics and dissemination Informed consent will be obtained from all participants. The results of this feasibility study will form the basis for refinement of NPRL and planning of a large-scale process and effect evaluation of the Quadruple Aim outcomes. Dissemination will include publications and presentations at national and international conferences. Ethical approval for this study was granted by the Medical Ethics Committee Z, the Netherlands, METC 17 N-133. [ABSTRACT FROM AUTHOR]

Purpose: To deliver client-centered care, physiotherapists need to identify the patients’ individual treatment goals. However, practical tools for involving patients in goal setting are lacking. The purpose of this study was to improve the frequently used Patient-Specific Complaints instrument in Dutch physiotherapy, and to develop it into a feasible method to improve physiotherapy goal setting. Methods: An iterative user-centered design was conducted in co-creation with the physiotherapists and patients, in three phases. Their needs and preferences were identified by means of group meetings and questionnaires. The new method was tested in several field tests in physiotherapy practices. Results: Four main objectives for improvement were formulated: clear instructions for the administration procedure, targeted use across the physiotherapy process, client-activating communication skills, and a client-centered attitude of the physiotherapist. A theoretical goal-setting framework and elements of shared decision making were integrated into the new-called, Patient-Specific Goal-setting method, together with a practical training course. Conclusions: The user-centered approach resulted in a goal-setting method that is fully integrated in the physiotherapy process. The new goal-setting method contributes to a more structured approach to goal setting and enables patient participation and goal-oriented physiotherapy. Before large-scale implementation, its feasibility in physiotherapy practice needs to be investigated. Implications for rehabilitation: Involving patients and physiotherapists in the development and testing of a goal-setting method, increases the likelihood of its feasibility in practice. The integration of a goal-setting method into the physiotherapy process offers the opportunity to focus more fully on the patient’s goals. Patients should be informed about the aim of every step of the goal-setting process in order to increase their awareness and involvement. Training physiotherapists to use a patient-specific method for goal setting is crucial for a correct application. [ABSTRACT FROM AUTHOR]

Pain is the predominant symptom for people with inflammatory arthritis (IA) and osteoarthritis (OA) mandating the development of evidence-based recommendations for the health professional's approach to pain management. A multidisciplinary task force including professionals and patient representatives conducted a systematic literature review of systematic reviews to evaluate evidence regarding effects on pain of multiple treatment modalities. Overarching principles and recommendations regarding assessment and pain treatment were specified on the basis of reviewed evidence and expert opinion. From 2914 review studies initially identified, 186 met inclusion criteria. The task force emphasised the importance for the health professional to adopt a patient-centred framework within a biopsychosocial perspective, to have sufficient knowledge of IA and OA pathogenesis, and to be able to differentiate localised and generalised pain. Treatment is guided by scientific evidence and the assessment of patient needs, preferences and priorities; pain characteristics; previous and ongoing pain treatments; inflammation and joint damage; and psychological and other pain-related factors. Pain treatment options typically include education complemented by physical activity and exercise, orthotics, psychological and social interventions, sleep hygiene education, weight management, pharmacological and joint-specific treatment options, or interdisciplinary pain management. Effects on pain were most uniformly positive for physical activity and exercise interventions, and for psychological interventions. Effects on pain for educational interventions, orthotics, weight management and multidisciplinary treatment were shown for particular disease groups. Underpinned by available systematic reviews and meta-analyses, these recommendations enable health professionals to provide knowledgeable pain-management support for people with IA and OA.

Background: Patient participation and goal setting appear to be difficult in daily physiotherapy practice, and practical methods are lacking. An existing patient-specific instrument, Patient-Specific Complaints (PSC), was therefore optimized into a new Patient Specific Goal-setting method (PSG). The aims of this study were to examine the feasibility of the PSG in daily physiotherapy practice, and to explore the potential impact of the new method.Methods: We conducted a process evaluation within a non-controlled intervention study. Community-based physiotherapists were instructed on how to work with the PSG in three group training sessions. The PSG is a six-step method embedded across the physiotherapy process, in which patients are stimulated to participate in the goal-setting process by: identifying problematic activities, prioritizing them, scoring their abilities, setting goals, planning and evaluating. Quantitative and qualitative data were collected among patients and physiotherapists by recording consultations and assessing patient files, questionnaires and written reflection reports.Results: Data were collected from 51 physiotherapists and 218 patients, and 38 recordings and 219 patient files were analysed. The PSG steps were performed as intended, but the 'setting goals' and 'planning treatment' steps were not performed in detail. The patients and physiotherapists were positive about the method, and the physiotherapists perceived increased patient participation. They became aware of the importance of engaging patients in a dialogue, instead of focusing on gathering information. The lack of integration in the electronic patient system was a major barrier for optimal use in practice. Although the self-reported actual use of the PSG, i.e. informing and involving patients, and client-centred competences had improved, this was not completely confirmed by the objectively observed behaviour.Conclusion: The PSG is a feasible method and tends to have impact on increasing patient participation in the goal-setting process. However, its full potential for shared goal setting has not been utilized yet. More implementation effort is needed to achieve the required behaviour change and a truly client-centred attitude, to make physiotherapists totally ready for shared goal setting.

Background: A multi-centre RCT has shown that multidisciplinary rehabilitation treatment (MRT) is more effective in reducing fatigue over the long-term in comparison with cognitive behavioural therapy (CBT) for patients with chronic fatigue syndrome (CFS), but evidence on its cost-effectiveness is lacking. Aim: To compare the cost-effectiveness of MRT versus CBT for patients with CFS from a societal perspective. Methods: A multi-centre randomized controlled trial comparing MRT with CBT was conducted among 122 patients with CFS diagnosed using the 1994 criteria of the Centers for Disease Control and Prevention and aged between 18 and 60 years. The societal costs (healthcare costs, patient and family costs, and costs for loss of productivity), fatigue severity, quality of life, quality-adjusted life-year (QALY), and cost-effectiveness ratios (ICERs) were measured over a follow-up period of one year. The main outcome of the cost-effectiveness analysis was fatigue measured by the Checklist Individual Strength (CIS). The main outcome of the cost-utility analysis was the QALY based on the EuroQol-5D-3L utilities. Sensitivity analyses were performed, and uncertainty was calculated using the cost-effectiveness acceptability curves and cost-effectiveness planes. Results: The data of 109 patients (57 MRT and 52 CBT) were analyzed. MRT was significantly more effective in reducing fatigue at 52 weeks. The mean difference in QALY between the treatments was not significant (0.09, 95% CI: -0.02 to 0.19). The total societal costs were significantly higher for patients allocated to MRT (a difference of €5,389, 95% CI: 2,488 to 8,091). MRT has a high probability of being the most cost effective, using fatigue as the primary outcome. The ICER is €856 per unit of the CIS fatigue subscale. The results of the cost-utility analysis, using the QALY, indicate that the CBT had a higher likelihood of being more cost-effective. Conclusions: The probability of being more cost-effective is higher for MRT when using fatigue as primary outcome variable. Using QALY as the primary outcome, CBT has the highest probability of being more cost-effective. Trial registration: . [ABSTRACT FROM AUTHOR]

An editorial is presented on the chronic pain in European population. It expresses the view that in line with an ageing population, the number of people with disability from CMP is rapidly increasing. An overview of the secondary and tertiary care, (rehabilitation) physicians and their teams will assist primary care by a focus on a select patient group with complex pain related disability is presented.

Before patients with chronic pain enter pain rehabilitation treatment, they are examined by an interdisciplinary team (i.e. a rehabilitation physician, physiotherapist and psychologist). To start treatment aimed at improving functioning, the patient and his practitioners need to have a shared understanding of the psychosocial factors contributing to the patient's disabilities. Since patients with chronic pain are often dismissive of the role of psychosocial factors, the Findings: of the team's examination are thoroughly discussed with the patient to reach consensus. This study explores how patients with chronic pain and their practitioners talk through the team's hypotheses regarding the psychosocial factors involved in the patient's pain problem. Nine consultations were recorded at various Dutch rehabilitation units, resulting in approximately 4,5 hours of audio material. All nine patients participating had chronic primary musculoskeletal pain. Seven practitioners participated. The recordings were transcribed and analysed on a micro-level combining an applied conversation analytic research approach with discursive psychology. When talking through the rehabilitation team's hypotheses regarding the psychosocial factors involved in the patient's health situation, both patients and practitioners orient to the institutional goal of reaching consensus. Patients display an orientation to agreement as the relevant response to practitioners' deliveries of the team's findings. And, when it remains unclear whether the patient is in agreement, practitioners tend to pursue an unequivocal response. They design their turns in ways that pre-empt resistance and encourage patients to confirm the team's findings, rather than to voice their own concerns and perspectives. Patients and practitioners' orientations to the institutional need for consensus, may hinder an open dialogue about patients' potentially different perspectives. Findings: can be used by practitioners to reflect on how they can develop communication practices that are more likely to bring patients' potential concerns regarding the rehabilitation team's Findings: out into the open.

Objectives: The 0-10 Numeric Rating Scale (NRS) is often used in pain management. The aims of our study were to determine the cut-off points for mild, moderate, and severe pain in terms of pain-related interference with functioning in patients with chronic musculoskeletal pain, to measure the variability of the optimal cut-off points, and to determine the influence of patients' catastrophizing and their sex on these cut-off points. Methods: 2854 patients were included. Pain was assessed by the NRS, functioning by the Pain Disability Index (PDI) and catastrophizing by the Pain Catastrophizing Scale (PCS). Cut-off point schemes were tested using ANOVAs with and without using the PSC scores or sex as co-variates and with the interaction between CP scheme and PCS score and sex, respectively. The variability of the optimal cut-off point schemes was quantified using bootstrapping procedure. Results and conclusion: The study showed that NRS scores ≤ 5 correspond to mild, scores of 6-7 to moderate and scores ≥ 8 to severe pain in terms of pain-related interference with functioning. Bootstrapping analysis identified this optimal NRS cut-off point scheme in 90% of the bootstrapping samples. The interpretation of the NRS is independent of sex, but seems to depend on catastrophizing. In patients with high catastrophizing tendency, the optimal cut-off point scheme equals that for the total study sample, but in patients with a low catastrophizing tendency, NRS scores ≤3 correspond to mild, scores of 4-6 to moderate and scores ≥7 to severe pain in terms of interference with functioning. In these optimal cut-off schemes, NRS scores of 4 and 5 correspond to moderate interference with functioning for patients with low catastrophizing tendency and to mild interference for patients with high catastrophizing tendency. Theoretically one would therefore expect that among the patients with NRS scores 4 and 5 there would be a higher average PDI score for those with low catastrophizing than for those with high catastrophizing. However, we found the opposite. The fact that we did not find the same optimal CP scheme in the subgroups with lower and higher catastrophizing tendency may be due to chance variability.
