Patient-reported improvements in health are maintained 2 years after completing a short course of cognitive behaviour therapy, exercise or both treatments for chronic widespread pain: long-term results from the MUSICIAN randomised controlled trial

Effects of a mindfulness-based and acceptance-based group programme followed by physical activity for patients with fibromyalgia: a randomised controlled trial

INTRODUCTION

Non-pharmacological approaches are recommended as first-line treatment for patients with fibromyalgia. This randomised controlled trial investigated the effects of a multicomponent rehabilitation programme for patients with recently diagnosed fibromyalgia in primary and secondary healthcare.

METHODS

Patients with widespread pain ≥3 months were referred to rheumatologists for diagnostic clarification and assessment of study eligibility. Inclusion criteria were age 20-50 years, engaged in work or studies at present or during the past 2 years, and fibromyalgia diagnosed according to the American College of Rheumatology 2010 criteria. All eligible patients participated in a short patient education programme before inclusion and randomisation. The multicomponent programme, a 10-session mindfulness-based and acceptance-based group programme followed by 12 weeks of physical activity counselling was evaluated in comparison with treatment as usual, that is, no treatment or any other treatment of their choice. The primary outcome was the Patient Global Impression of Change (PGIC). Secondary outcomes were self-reported pain, fatigue, sleep quality, psychological distress, physical activity, health-related quality of life and work ability at 12-month follow-up.

RESULTS

In total, 170 patients were randomised, 1:1, intervention:control. Overall, the multicomponent rehabilitation programme was not more effective than treatment as usual; 13% in the intervention group and 8% in the control group reported clinically relevant improvement in PGIC (p=0.28). No statistically significant between-group differences were found in any disease-related secondary outcomes. There were significant between-group differences in patient's tendency to be mindful (p=0.016) and perceived benefits of exercise (p=0.033) in favour of the intervention group.

CONCLUSIONS

A multicomponent rehabilitation programme combining patient education with a mindfulness-based and acceptance-based group programme followed by physical activity counselling was not more effective than patient education and treatment as usual for patients with recently diagnosed fibromyalgia at 12-month follow-up.

Intervention Therapies to Reduce Pain-Related Fear in Fibromyalgia Syndrome: A Systematic Review of Randomized Clinical Trials

OBJECTIVE

This systematic review aimed to evaluate the effectiveness of different interventions at reducing pain-related fear in people with fibromyalgia and to analyze whether the included trials reported their interventions in full detail.

DESIGN

Systematic review.

SETTING

No restrictions.

METHODS

The Cochrane Library, CINAHL, EMBASE, PsycINFO, PubMed, and Scopus were searched from their inception to April 2020, along with manual searches and a gray literature search. Randomized clinical trials were included if they assessed pain-related fear constructs as the primary or secondary outcome in adults with fibromyalgia. Two reviewers independently performed the study selection, data extraction, risk-of-bias assessment, Template for Intervention Description and Replication (TIDieR) checklist assessment, and grading the quality of evidence.

RESULTS

Twelve randomized clinical trials satisfied the eligibility criteria, including 11 cohorts with a total sample of 1,441 participants. Exercise, multicomponent, and psychological interventions were more effective than controls were in reducing kinesiophobia. However, there were no differences in decreasing kinesiophobia when self-management and electrotherapy were used. There were also no differences between groups with regard to the rest of the interventions and pain-related constructs (fear-avoidance beliefs, fear of pain, and pain-related anxiety). However, a serious risk of bias and a very serious risk of imprecision were detected across the included trials. This caused the overall certainty of the judged evidence to be low and very low. Additionally, the included trials reported insufficient details to allow the full replication of their interventions.

CONCLUSIONS

This systematic review shows that there are promising interventions, such as exercise, multicomponent, and psychological therapies, that may decrease one specific type of fear in people with fibromyalgia, i.e., kinesiophobia. However, because of the low-very low certainty of the evidence found, a call for action is needed to improve the quality of randomized clinical trials, which will lead to more definitive information about the clinical efficacy of interventions in this field.

Maintaining musculoskeletal health using a behavioural therapy approach: a population-based randomised controlled trial (the MAmMOTH Study)

Objective

Cognitive–behavioural therapy (CBT) has been shown to be effective in the management of chronic widespread pain (CWP); we now test whether it can prevent onset among adults at high risk.

Methods

A population-based randomised controlled prevention trial, with recruitment through UK general practices. A mailed screening questionnaire identified adults at high risk of CWP. Participants received either usual care (UC) or a short course of telephone CBT (tCBT). The primary outcome was CWP onset at 12 months assessed by mailed questionnaire. There were seven secondary outcomes including quality of life (EuroQol Questionnaire-five dimensions-five levels/EQ-5D-5L) used as part of a health economic assessment.

Results

996 participants were randomised and included in the intention-to-treat analysis of which 825 provided primary outcome data. The median age of participants was 59 years; 59% were women. At 12 months there was no difference in the onset of CWP (tCBT: 18.0% vs UC: 17.5%; OR 1.05; 95% CI 0.75 to 1.48). Participants who received tCBT were more likely to report better quality of life (EQ-5D-5L utility score mean difference 0.024 (95% CI 0.009 to 0.040)); and had 0.023 (95% CI 0.007 to 0.039) more quality-adjusted life-years at an additional cost of £42.30 (95% CI −£451.19 to £597.90), yielding an incremental cost-effectiveness ratio of £1828. Most secondary outcomes showed significant benefit for the intervention.

Conclusions

A short course of tCBT did not prevent onset of CWP in adults at high risk, but improved quality of life and was cost-effective. A low-cost, short-duration intervention benefits persons at risk of CWP.

Feasibility, acceptability and change in health following a telephone-based cognitive behaviour therapy intervention for patients with axial spondyloarthritis

Objective

The aim was to assess the feasibility and acceptability of a telephone-based cognitive behaviour therapy (tCBT) intervention for individuals with axial SpA (axSpA), with and without co-morbid FM, and to measure the change in patient-reported health outcomes.

Methods

A convenience sample of individuals recruited from British Society for Rheumatology Biologics Registry for AS (BSRBR-AS) sites were offered a course of tCBT (framed as coaching). Patient-reported outcomes were measured at baseline and on course completion. Semi-structured qualitative interviews assessed intervention acceptability. Thematic analysis was informed by the theoretical framework of acceptability.

Results

Forty-two participants attended for initial assessment. Those completing at least one tCBT session (n = 28) were younger, more likely to meet classification criteria for FM (57 vs 29%) and reported higher disease activity. Modest improvements were reported across a range of disease activity and wider health measures, with 62% of patients self-rating their health as improved (median 13 weeks post-intervention). Twenty-six participants were interviewed (including six who discontinued after initial assessment). tCBT was widely acceptable, offering a personalized approach. Despite low or unclear expectations, participants described improved sleep and psychological well-being and gained new skills to support self-management. Reasons for non-uptake of tCBT centred on lack of perceived need and fit with individual value systems. Many felt that tCBT would be most useful closer to diagnosis.

Conclusion

Higher uptake among axSpA patients with co-morbid FM suggests that these individuals have additional needs. The findings are helpful in identifying patients most likely to engage with and benefit from tCBT and to maximize participation.

Behavioural modification interventions for medically unexplained symptoms in primary care: systematic reviews and economic evaluation

BACKGROUND

The term 'medically unexplained symptoms' is used to cover a wide range of persistent bodily complaints for which adequate examination and appropriate investigations do not reveal sufficiently explanatory structural or other specified pathologies. A wide range of interventions may be delivered to patients presenting with medically unexplained symptoms in primary care. Many of these therapies aim to change the behaviours of the individual who may have worsening symptoms.

OBJECTIVES

An evidence synthesis to determine the clinical effectiveness and cost-effectiveness of behavioural modification interventions for medically unexplained symptoms delivered in primary care settings was undertaken. Barriers to and facilitators of the effectiveness and acceptability of these interventions from the perspective of patients and service providers were evaluated through qualitative review and realist synthesis.

DATA SOURCES

Full search strategies were developed to identify relevant literature. Eleven electronic sources were searched. Eligibility criteria - for the review of clinical effectiveness, randomised controlled trials were sought. For the qualitative review, UK studies of any design were included. For the cost-effectiveness review, papers were restricted to UK studies reporting outcomes as quality-adjusted life-year gains. Clinical searches were conducted in November 2015 and December 2015, qualitative searches were conducted in July 2016 and economic searches were conducted in August 2016. The databases searched included MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and EMBASE. Updated searches were conducted in February 2019 and March 2019.

PARTICIPANTS

Adult participants meeting the criteria for medically unexplained symptoms, including somatoform disorders, chronic unexplained pain and functional somatic syndromes.

INTERVENTIONS

Behavioural interventions were categorised into types. These included psychotherapies, exercise-based interventions, multimodal therapies (consisting of more than one intervention type), relaxation/stretching/social support/emotional support, guided self-help and general practitioner interventions, such as reattribution. Evidence synthesis: a network meta-analysis was conducted to allow a simultaneous comparison of all evaluated interventions in a single coherent analysis. Separate network meta-analyses were performed at three time points: end of treatment, short-term follow-up (< 6 months since the end of treatment) and long-term follow-up (≥ 6 months after the end of treatment). Outcomes included physical and psychological symptoms, physical functioning and impact of the illness on daily activities. Economic evaluation: within-trial estimates of cost-effectiveness were generated for the subset of studies where utility values (or quality-adjusted life-years) were reported or where these could be estimated by mapping from Short Form questionnaire-36 items or Short Form questionnaire-12 items outcomes.

RESULTS

Fifty-nine studies involving 9077 patients were included in the clinical effectiveness review. There was a large degree of heterogeneity both between and within intervention types, and the networks were sparse across all outcomes. At the end of treatment, behavioural interventions showed some beneficial effects when compared with usual care, in particular for improvement of specific physical symptoms [(1) pain: high-intensity cognitive-behavioural therapy (CBTHI) standardised mean difference (SMD) 0.54 [95% credible interval (CrI) 0.28 to 0.84], multimodal SMD 0.52 (95% CrI 0.19 to 0.89); and (2) fatigue: low-intensity cognitive-behavioural therapy (CBTLI) SMD 0.72 (95% CrI 0.27 to 1.21), relaxation/stretching/social support/emotional support SMD 0.87 (95% CrI 0.20 to 1.55), graded activity SMD 0.51 (95% CrI 0.14 to 0.93), multimodal SMD 0.52 (95% CrI 0.14 to 0.92)] and psychological outcomes [(1) anxiety CBTHI SMD 0.52 (95% CrI 0.06 to 0.96); (2) depression CBTHI SMD 0.80 (95% CrI 0.26 to 1.38); and (3) emotional distress other psychotherapy SMD 0.58 (95% CrI 0.05 to 1.13), relaxation/stretching/social support/emotional support SMD 0.66 (95% CrI 0.18 to 1.28) and sport/exercise SMD 0.49 (95% CrI 0.03 to 1.01)]. At short-term follow-up, behavioural interventions showed some beneficial effects for specific physical symptoms [(1) pain: CBTHI SMD 0.73 (95% CrI 0.10 to 1.39); (2) fatigue: CBTLI SMD 0.62 (95% CrI 0.11 to 1.14), relaxation/stretching/social support/emotional support SMD 0.51 (95% CrI 0.06 to 1.00)] and psychological outcomes [(1) anxiety: CBTHI SMD 0.74 (95% CrI 0.14 to 1.34); (2) depression: CBTHI SMD 0.93 (95% CrI 0.37 to 1.52); and (3) emotional distress: relaxation/stretching/social support/emotional support SMD 0.82 (95% CrI 0.02 to 1.65), multimodal SMD 0.43 (95% CrI 0.04 to 0.91)]. For physical functioning, only multimodal therapy showed beneficial effects: end-of-treatment SMD 0.33 (95% CrI 0.09 to 0.59); and short-term follow-up SMD 0.78 (95% CrI 0.23 to 1.40). For impact on daily activities, CBTHI was the only behavioural intervention to show beneficial effects [end-of-treatment SMD 1.30 (95% CrI 0.59 to 2.00); and short-term follow-up SMD 2.25 (95% CrI 1.34 to 3.16)]. Few effects remained at long-term follow-up. General practitioner interventions showed no significant beneficial effects for any outcome. No intervention group showed conclusive beneficial effects for measures of symptom load (somatisation). A large degree of heterogeneity was found across individual studies in the assessment of cost-effectiveness. Several studies suggested that the interventions produce fewer quality-adjusted life-years than usual care. For those interventions that generated quality-adjusted life-year gains, the mid-point incremental cost-effectiveness ratios (ICERs) ranged from £1397 to £129,267, but, where the mid-point ICER fell below £30,000, the exploratory assessment of uncertainty suggested that it may be above £30,000.

LIMITATIONS

Sparse networks meant that it was not possible to conduct a metaregression to explain between-study differences in effects. Results were not consistent within intervention type, and there were considerable differences in characteristics between studies of the same type. There were moderate to high levels of statistical heterogeneity. Separate analyses were conducted for three time points and, therefore, analyses are not repeated-measures analyses and do not account for correlations between time points.

CONCLUSIONS

Behavioural interventions showed some beneficial effects for specific medically unexplained symptoms, but no one behavioural intervention was effective across all medically unexplained symptoms. There was little evidence that these interventions are effective for measures of symptom load (somatisation). General practitioner-led interventions were not shown to be effective. Considerable heterogeneity in interventions, populations and sparse networks mean that results should be interpreted with caution. The relationship between patient and service provider is perceived to play a key role in facilitating a successful intervention. Future research should focus on testing the therapeutic effects of the general practitioner-patient relationship within trials of behavioural interventions, and explaining the observed between-study differences in effects within the same intervention type (e.g. with more detailed reporting of defined mechanisms of the interventions under study).

Altered functional connectivity associated with time discounting in chronic pain

Chronic pain (CP) is a global problem extensively associated with an unhealthy lifestyle. Time discounting (TD), a tendency to assign less value to future gains than to present gains, is an indicator of the unhealthy behaviors. While, recent neuroimaging studies implied overlapping neuro mechanisms underlying CP and TD, little is known about the specific relationship between CP and TD in behavior or neuroscience. As such, we investigated the association of TD with behavioral measures in CP and resting-state brain functional network in both CP patients and healthy subjects. Behaviorally, TD showed a significant correlation with meaningfulness in healthy subjects, whereas TD in patients only correlated with pain intensity. We identified a specific network including medial and dorsolateral prefrontal cortex (PFC) in default mode network (DMN) associated with TD in healthy subjects that showed significant indirect mediation effect of meaningfulness on TD. In contrast, TD in patients was correlated with functional connectivity between dorsolateral PFC (DLPFC) and temporal lobe that mediated the effect of pain intensity on TD in patients. These results imply that TD is modulated by pain intensity in CP patients, and the brain function associated to TD is shifted from a medial to lateral representation within the frontal regions.

Telephone cognitive behavioural therapy to prevent the development of chronic widespread pain: a qualitative study of patient perspectives and treatment acceptability

Background

Telephone cognitive behavioural therapy (tCBT) is an acceptable and effective treatment for patients with chronic widespread pain (CWP). Preventing the onset of CWP offers considerable benefits to the individual and society and the MAmMOTH study is the first aimed at CWP prevention. The study is a two-arm randomised trial testing a course of tCBT against usual care for prevention of CWP. This nested qualitative study explores patients’ treatment experiences, with a view to understanding their potential influences on acceptability of the intervention.

Methods

The MAmMOTH Study recruited 1002 participants, half of whom were randomised to receive tCBT. Participants were eligible for invitation to the trial if they had pain for which they had consulted their GP, or had pain and visited a doctor frequently, and had 2 of 3 risk factors for development of CWP. Participants randomised to tCBT who had completed treatment were eligible for invitation to qualitative interviews for this study. Individual qualitative interviews were conducted with a sub-sample (n = 33) of patients at high risk of developing CWP who had been allocated to the intervention arm. Semi-structured telephone interviews explored treatment experiences and intervention acceptability. Data was analysed using Framework analysis.

Results

Participants presented with a range of musculoskeletal and auto-immune conditions and almost half described their pain as ‘chronic’ on study entry. Many participants perceived the trial intervention to be aimed at treatment of pain rather than prevention of pain. Initial expectations prior to treatment varied, with scepticism more likely for those who had little prior knowledge of CBT approaches. All participants provided positive feedback post intervention particularly in relation to the modality, therapist experience and skills and the intervention. The majority of participants described positive changes in either their subjective level of pain or pain-management post-intervention and some attributed the positive change directly to the intervention as a result of empowerment, increased self-management and cognitive restructuring.

Conclusions

This study extends our understanding of the acceptability and suitability of preventative interventions for chronic widespread pain and provides further evidence for the acceptability of tCBT.

Differences in long-term physical activity trajectories among individuals with chronic widespread pain: A secondary analysis of a randomized controlled trial

BACKGROUND

Little is known about long-term physical activity (PA) maintenance in those with chronic widespread pain (CWP) following an exercise intervention. This study examined PA over time to identify the existence and characteristics of subgroups following distinct PA trajectories.

METHODS

Data come from individuals with CWP who took part in a 2 × 2 factorial randomized controlled trial, receiving either exercise or both exercise and cognitive behavioural therapy treatment. Information, including self-report PA, was collected at baseline recruitment, immediately post-intervention, 3, 24 and 60+ month post-treatment. Analyses were conducted on 196 men and women with ≥ 3 PA data points. Group-based trajectory modelling was used to identify latent PA trajectory groups and baseline characteristics (e.g., demographics, pain, self-rated health, fatigue, coping-strategy use and kinesiophobia) of these groups.

RESULTS

The best fitting model identified was one with three trajectories: "non-engagers" (n = 32), "maintainers" (n = 144) and "super-maintainers" (n = 20). Overall, mean baseline PA levels were significantly different between groups (non-engagers: 1.1; maintainers: 4.6; super-maintainers: 8.6, p < 0.001) and all other follow-up points. Non-engagers reported, on average, greater BMI, higher disabling chronic pain, poorer self-rated health, physical functioning, as well as greater use of passive coping strategies and lower use of active coping strategies.

CONCLUSIONS

The majority of individuals with CWP receiving exercise as part of a trial were identified as long-term PA maintainers. Participants with poorer physical health and coping response to symptoms were identified as non-engagers. For optimal symptom management, a stratified approach may enhance initiation and long-term PA maintenance in individuals with CWP.

SIGNIFICANCE

Chronic pain can be a major barrier to engaging in exercise, a popular self-management strategy. Our findings identify three distinct long-term physical activity trajectories for individuals receiving the same exercise intervention. This suggests an approach by health care providers which identifies individuals who would benefit from additional support to enhance initiation and long-term physical activity maintenance could deliver better outcomes for such patients.

The effectiveness of exercise-based telemedicine on pain, physical activity and quality of life in the treatment of chronic pain: A systematic review

Introduction The aim of this study was to systematically review the evidence on the effectiveness of exercise-based telemedicine in chronic pain. Methods We searched the Cochrane, PubMed, MEDLINE, EMBASE, CINAHL and PEDRO databases from 2000 to 2015 for randomised controlled trials, comparing exercise-based telemedicine intervention to no intervention or usual care in adults with chronic pain. Primary outcome data were pooled using random effect meta-analysis. Primary outcomes were pain, physical activity (PA), limitations in activities of daily living (ADL) and quality of life (QoL). Secondary outcomes were barriers, facilitators and usability of telemedicine. Results Sixteen studies were included. Meta-analyses were performed in three subgroups of studies with comparable control conditions. Telemedicine versus no intervention showed significantly lower pain scores (MD -0.57, 95% CI -0.81; -0.34), but not for telemedicine versus usual care (MD -0.08, 95% CI -0.41; 0.26) or in addition to usual care (MD -0.25, 95% CI -1.50; 1.00). Telemedicine compared to no intervention showed non-significant effects for PA (MD 19.93 min/week, 95% CI -5.20; 45.06) and significantly diminished ADL limitations (SMD -0.20, 95% CI -0.29; -0.12). No differences were found for telemedicine in addition to usual care for PA or for ADL (SMD 0.16, 95% CI -0.66; 0.34). Telemedicine versus usual care showed no differences for ADL (SMD 0.08, 95% CI -0.37; 0.53). No differences were found for telemedicine compared to the three control groups for QoL. Limited information was found on the secondary outcomes. Conclusions Exercise-based telemedicine interventions do not seem to have added value to usual care. As substitution of usual care, telemedicine might be applicable but due to limited quality of the evidence, further exploration is needed for the rapidly developing field of telemedicine.

A qualitative study of professional stakeholders' perceptions about the implementation of a stepped care pain platform for people experiencing chronic widespread pain

Background

Chronic widespread pain (CWP) is a major public health problem. Many people experiencing CWP experience mental health problems such as anxiety or depression. Complete relief of skeletal and body pain symptoms is unlikely but with appropriate treatment the impact upon quality of life, functioning and mental health symptoms can be reduced. Cognitive behavioural therapy (CBT) is widely used for a range of health conditions and can have short and long-term improvements in patients with CWP. This research aimed to explore, from a professional stakeholder perspective, the implementation of a local Pain Platform offering a stepped care approach for interventions including telephone delivered CBT (T-CBT).

Methods

Fourteen professional stakeholders holding various roles across primary and secondary care services within the Pain Platform took part in semi-structured interviews. Their views and experiences of the implementation of the Pain Platform were explored. Interviews were recorded, transcribed verbatim and analysed according to Normalisation Process Theory (NPT).

Results

Professional stakeholders were positive about the Pain Platform and its potential to overcome previously identified existing access issues to psychological interventions for CWP patients. It was considered a valuable part of ensuring that patients’ preferences and needs are more readily addressed. In some circumstances, however, introducing psychological interventions to patients was considered challenging and the introduction of new referral processes was raised concerns. To ensure sustainability more work is required to reduce professional isolation and ensure efficient referral procedures between primary and secondary care services are established to reduce concerns over issues related to clinical governance and potential risk to patient.

Conclusions

The findings provide professional insight into the key challenges of introducing a Pain Platform incorporating psychological support across primary and secondary care services within a local service. These included development of sustainable procedures and closer working relationships. Areas requiring future development are identified.

Effects of a community-based multicomponent rehabilitation programme for patients with fibromyalgia: protocol for a randomised controlled trial

INTRODUCTION

People with fibromyalgia (FM) suffer from symptoms such as widespread pain, non-refreshing sleep, fatigue and reduced quality of life. Effects of pharmacological treatment are questionable and non-pharmacological treatments are recommended as first-line therapy. To date the majority of patients with FM in Norway are not offered any targeted treatment. The aim of this randomised controlled trial is to investigate the effects of a community-based multicomponent rehabilitation programme comprising an acceptance-based and mindfulness-based group intervention, the Vitality Training Programme (VTP), followed by tailored physical activity counselling.

MATERIALS AND METHODS

General practitioners refer potential participants to a rheumatologist in specialist healthcare for diagnostic clarification and assessment of comorbidities. Inclusion criteria are widespread pain/FM ≥3 months, age 20-50 and work participation (minimum part-time) within the last 2 years. The intervention group attends the VTP comprising 10 weekly 4 hour group sessions plus a booster session after 6 months. Thereafter, they receive 12 weeks of individually tailored physical exercise counselled by physiotherapists at community-based Healthy Life Centers. The control group follows treatment as usual. The primary outcome is Patient Global Impression of Change. Secondary outcomes include self-reported pain, fatigue and sleep quality, psychological distress, mindfulness, health-related quality of life, physical activity, work ability and exercise beliefs and habits. To achieve a power of 80% and allow for 10% dropout, 70 participants are needed in each arm. All analyses will be conducted on intention-to-treat bases and measured as differences between groups at 12 months follow-up.

ETHICS AND DISSEMINATION

The study is approved and granted by the Norwegian South-Eastern Regional Health Authority (reference 2016015). Ethics approval was obtained from Regional Committee for Medical and Health Research Ethics (reference 2015/2447/REK sør-øst A). Results will be submitted to appropriate journals and presented in relevant conferences and social media.

Sleep and physical activity: a cross-sectional objective profile of people with rheumatoid arthritis

Regular physical activity (PA) is important for people with rheumatoid arthritis (RA). Poor sleep is a common complaint among people with RA, which may have an influence on their PA levels. There is a lack of objective information regarding total sleep time (TST) and PA duration in this population. A cross-sectional study design was used. SenseWear Pro3 Armband^(R)TM is used to measure TST and total PA duration. Four valid days, with 95% wear time necessary for inclusion in final results. Disease activity and function were measured using the DAS-28, HAQ and VAS. Data analysis carried out using SPSS v22. Seventy-five (75) participants completed monitoring period, with 51 (68%) meeting modified PA duration guidelines. Data with 95% wear time over a minimum of 4 days were available for 32 recorded participants, with a mean TST of 5.7 (SD_1.11) hours per night and a median 1.25 (IQR_1.88) hours of daily PA. TST had a positive significant relationship with PA (p = 0.018); PA demonstrated a negative significant relationship with functional limitations (p = 0.009) and correlated with lower CRP levels; CRP levels had in turn a significant relationship to global health (p = 0.034). Total sleep time was low for people with RA. People with RA who are more physically active have longer TST. These findings provide an objective profile of TST and PA duration in people with RA and suggest a relationship between increased PA duration and longer TST. Further research is needed to confirm these novel findings.

Improved health-related quality of life, participation, and autonomy in patients with treatment-resistant chronic pain after an intensive social cognitive intervention with the participation of support partners

Despite the availability of various specific treatments, most patients with chronic pain (CP) consider their pain problem as undertreated. Recently, multiple sclerosis (MS) patients who were given an intensive 3-day social cognitive treatment with the participation of support partners experienced lasting improvements in health-related quality of life (HRQoL) and self-efficacy. In this study, a similar intervention was given to treatment-resistant CP patients with stressors, relational problems with support partner, and distress, anxiety or depression. Before and 1, 3, and 6 months after the intervention, patients completed the Euro-Qol 5 Dimensions 5 Levels (EQ-5D-5L) and Impact on Participation and Autonomy (IPA) questionnaires (primary outcomes), and the Survey Of Pain Attitudes (SOPA), the Four-Dimensional Symptom Questionnaire (4DSQ) (distress, depression, anxiety, and somatization), and Visual Analog Scale for pain intensity, whereas the support partners completed the Caregiver Strain Index (CSI) questionnaire. Differences between baseline and post-treatment were tested via paired t-tests (significance level 0.05). Of the 39 patients who were included, 34 (87.2%) completed the 3-day treatment. At 1, 3, and 6 months, improvements were seen in EQ-5D-5L-Index (+40.6%; +22.4%; +31.7%), Health Today (+61.8%; +36.3%; +46.8%), Control attitude (+45.8%; not significant [NS]; +55.0%) and decreases in IPA-Problems (−14.8%; NS; −20.4%), Harm attitude (−18.9%; −15.0%; −17.7%), Distress (−17.7%; −31.8%; −37.1%), and Depression (−37.4%; −31.4%; −35.7%) scores. The CSI score had decreased by −29.0%, −21.4%, and −25.9%, respectively. In conclusion, after an intensive 3-day social cognitive intervention, treatment-resistant CP patients experienced substantial and lasting improvements in HRQoL and in problematic limitations to participation and autonomy, in association with improvements in pain attitudes, depression, and distress. To assess whether this innovative approach may be an effective treatment for this subgroup of CP patients, future randomized controlled studies are needed.

Investigating generalizability of results from a randomized controlled trial of the management of chronic widespread pain: the MUSICIAN study

Trials are rarely able to evaluate the external validity of their results. This study demonstrates differences between eligible participants/nonparticipants and quantifies the effect on results.

The generalisability of randomised controlled trials will be compromised if markers of treatment outcome also affect trial recruitment. In a large trial of chronic widespread pain, we aimed to determine the extent to which randomised participants represented eligible patients, and whether factors predicting randomisation also influenced trial outcome. Adults from 8 UK general practices were surveyed to determine eligibility for a trial of 2 interventions (exercise and cognitive behavioural therapy [CBT]). Amongst those eligible, logistic regression identified factors associated with reaching the randomisation step in the recruitment process. The main trial analysis was recomputed, weighting for the inverse of the likelihood of reaching the randomisation stage, and the numbers needed to treat were calculated for each treatment. Eight hundred eighty-four persons were identified as eligible for the trial, of whom 442 (50%) were randomised. Several factors were associated with the likelihood of reaching the randomisation stage: higher body mass index (odds ratio: 1.99; 0.85-4.61); more severe/disabling pain (1.90; 1.21-2.97); having a treatment preference (2.11; 1.48-3.00); and expressing positivity about interventions offered (exercise: 2.66; 1.95-3.62; CBT: 3.20; 2.15-4.76). Adjusting for this selection bias decreased the treatment effect associated with exercise and CBT but increased that observed for combined therapy. All were associated with changes in numbers needed to treat. This has important implications for the design and interpretation of pain trials generally.

Treatment expectations but not preference affect outcome in a trial of CBT and exercise for pain

Background: Patients' beliefs and attitudes toward a treatment can affect treatment response. In unblinded trials this can affect outcomes. Aims: The aim of this analysis was to examine the association between treatment preference and expectation and outcome in a trial of pain treatments. Methods: In a randomized trial (ISRCTN67013851) of four treatments for chronic widespread pain, participants were asked which they would prefer and what improvement they expect from each. The proportion of participants reporting positive health outcomes at three time points after treatment were compared between those matched or unmatched with their preference and between those with and without expectation for improvement. Odds ratios were calculated adjusted for baseline characteristics associated with preference and expectation. Results: Four hundred forty-two participants were recruited to the trial (69.5% female). The proportion reporting positive outcomes among participants matched to their preference compared to those unmatched was 33.3% vs. 34.4% at the end of treatment (adjusted odds ratio [aOR] = 0.80, 95% confidence interval [CI], 0.44-1.46), 34.4% vs. 29.0% at 3 months (aOR = 1.23, 95% CI, 0.67-2.26), and 34.8% vs. 30.3% at 2 years (aOR = 1.31, 95% CI, 0.70-2.46). The proportion of participants reporting positive outcomes among those expecting improvement compared to those not expecting improvement was 36.6% vs. 15.0% at the end of treatment (aOR = 2.03, 95% CI, 1.07-3.85), 34.1% vs. 13.2% at 3 months (aOR = 2.31, 95% CI, 1.22-4.38), and 32.8% vs. 19.1% at 2 years (aOR = 1.16, 95% CI, 0.67-2.36). Conclusions: Treatment preference had no clear effect on outcomes, but expectation did. These results could inform future approaches to management, and researchers assessing treatments should take into account this expectation effect.

Specialist treatment of chronic fatigue syndrome/ME: a cohort study among adult patients in England

BACKGROUND

NHS specialist chronic fatigue syndrome (CFS/ME) services in England treat approximately 8000 adult patients each year. Variation in therapy programmes and treatment outcomes across services has not been described.

METHODS

We described treatments provided by 11 CFS/ME specialist services and we measured changes in patient-reported fatigue (Chalder, Checklist Individual Strength), function (SF-36 physical subscale, Work & Social Adjustment Scale), anxiety and depression (Hospital Anxiety & Depression Scale), pain (visual analogue rating), sleep (Epworth, Jenkins), and overall health (Clinical Global Impression) 1 year after the start of treatment, plus questions about impact of CFS/ME on employment, education/training and domestic tasks/unpaid work. A subset of these outcome measures was collected from former patients 2-5 years after assessment at 7 of the 11 specialist services.

RESULTS

Baseline data at clinical assessment were available for 952 patients, of whom 440 (46.2%) provided 1-year follow-up data. Treatment data were available for 435/440 (98.9%) of these patients, of whom 175 (40.2%) had been discharged at time of follow-up. Therapy programmes varied substantially in mode of delivery (individual or group) and number of sessions. Overall change in health 1 year after first attending specialist services was 'very much' or 'much better' for 27.5% (115/418) of patients, 'a little better' for 36.6% (153/418), 'no change' for 15.8% (66/418), 'a little worse' for 12.2% (51/418), and 'worse' or 'very much worse' for 7.9% (33/418). Among former patients who provided 2- to 5-year follow-up (30.4% (385/1265)), these proportions were 30.4% (117/385), 27.5% (106/385), 11.4% (44/385), 13.5% (52/385), and 17.1% (66/385), respectively. 85.4% (327/383) of former patients responded "Yes" to "Do you think that you are still suffering from CFS/ME?" 8.9% (34/383) were "Uncertain", and 5.7% (22/383) responded "No".

CONCLUSIONS

This multi-centre NHS study has shown that, although one third of patients reported substantial overall improvement in their health, CFS/ME is a long term condition that persists for the majority of adult patients even after receiving specialist treatment.

Management of Widespread Pain and Fibromyalgia

Specialists' views of fibromyalgia (FM) are typically colored by their experiences of the selected, complex cases that they are regularly called to evaluate. At a population level, it is crucial to recognize that education which promotes patient empowerment and non-pharmacological interventions which support self-management are very effective. The temptation, for both physician and patient, to first reach for pharmacological interventions should be resisted until such holistic approaches are explored. In particular, a strong evidence base supports graded exercise and cognitive behavioral therapies, but such treatments must be intelligently "prescribed." As reflected by the recent ACR criteria, FM is a highly heterogeneous disorder and is not simply a disorder of pain. For some patients, co-occurring symptoms, such as fatigue, can be equally as impactful and so management strategies should be sufficiently versatile to target those dimensions which are considered priorities at the level of the individual patient. In those patients who do require pharmacological support, patients should not be led to expect significant gains in isolation. The importance of self-management requires emphasis at each and every tier of management. It is true that advances in our understanding of neurobiology have greatly informed the selection of adjunctive drug classes which may provide benefit (as well as those which do not-as is the case of opioids). However, further unpicking of pathogenesis is still required if the FM landscape is to move further towards drug-led management.

Describing the characteristics, treatment pathways, outcomes, and costs of people with persistent noncancer pain managed by community pain clinics and generating an indicative estimate of cost-effectiveness: feasibility study protocol

Background

Low back pain (LBP) and fibromyalgia (FM), also known as chronic widespread pain (CWP), are highly prevalent chronic painful conditions that have substantial impact on patients, health care systems, and society. Diagnosis is complex and management strategies are associated with various levels of evidence for effectiveness and cost-effectiveness. Multidisciplinary pain services have been shown to be effective in some settings and therefore are recommended by clinical practice guidelines as a rational treatment option to manage these patients. Knowing that these services are resource intensive, evidence is needed to demonstrate their cost-effectiveness. This study aims to describe the management of patients with LBP and FM in two community pain clinics to derive an indicative estimate of cost-effectiveness compared with standard practice.

Methods

This is a prospective observational multicenter study, using patient-level data. The data from this study will be combined with modelling of the long-term economic impact of community pain clinics in treating people with LBP and FM. Newly referred patients with LBP and FM who provide written consent will be included. We will collect data on functional disability, pain intensity, quality of life, and health resource utilization. Follow-up data at the 3- and 6-month points will be collected by patient-completed questionnaires and health care contact diaries. Health care resource use from diaries will be compared with patient electronic records to assess the agreement between these recording methods. Patient cohort characteristics, treatment pathways, resource use, and outcomes derived from this study will be integrated in a decision analysis model to assess the cost-effectiveness of community pain clinics compared with standard care. This feasibility study will address key methodological issues such as sample estimates and retention rate to inform the design of a future randomized controlled trial.

The Maintaining Musculoskeletal Health (MAmMOTH) Study: Protocol for a randomised trial of cognitive behavioural therapy versus usual care for the prevention of chronic widespread pain

BACKGROUND

Cognitive behavioural therapy (CBT) has been shown to improve outcomes for patients with fibromyalgia, and its cardinal feature chronic widespread pain (CWP). Prediction models have now been developed which identify groups who are at high-risk of developing CWP. It would be beneficial to be able to prevent the development of CWP in these people because of the high cost of symptoms and because once established they are difficult to manage. We will test the hypothesis that among patients who are identified as at high-risk, a short course of telephone-delivered CBT (tCBT) reduces the onset of CWP. We will further determine the cost-effectiveness of such a preventative intervention.

METHODS

The study will be a two-arm randomised trial testing a course of tCBT against usual care for prevention of CWP. Eligible participants will be identified from a screening questionnaire sent to patients registered at general practices within three Scottish health boards. Those returning questionnaires indicating they have visited their doctor for regional pain in the last 6 months, and who have two of, sleep problems, maladaptive behaviour response to illness, or high number of somatic symptoms, will be invited to participate. After giving consent, participants will be randomly allocated to either tCBT or usual care. We aim to recruit 473 participants to each treatment arm. Participants in the tCBT group will have an initial assessment with a CBT therapist by telephone, then 6 weekly sessions, and booster sessions 3 and 6 months after treatment start. Those in the usual care group will receive no additional intervention. Follow-up questionnaires measuring the same items as the screening survey questionnaire will be sent 3, 12 and 24 months after start of treatment. The main outcome will be CWP at the 12 month questionnaire.

DISCUSSION

This will be the first trial of an intervention aimed at preventing fibromyalgia or CWP. The results of the study will help to inform future treatments for the prevention of chronic pain, and aetiological models of its development.

Involvement of the multidisciplinary team and outcomes in inpatient rehabilitation among patients with inflammatory rheumatic disease

Background

The last decades have for patients with inflammatory rheumatic diseases seen a shift towards more physically active rehabilitation programs, often provided as out-patients with less use of inpatient facilities. There is little research on which effect the multidisciplinary team has on health outcomes for patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and connective tissue disease. This study examined patient reported outcomes for patients with inflammatory rheumatic diseases receiving rehabilitation care as inpatients in departments of rheumatology, and studied how number of consultations with the multidisciplinary team affected these clinical outcomes.

Methods

Patients with inflammatory rheumatic diseases were included in a multi-center prospective observational study if rehabilitation was considered a focus during an inpatient stay at four departments of rheumatology. At admission, discharge, and after 3 and 6 months, 317 patients were assessed with patients reported outcomes (PRO) including health assessment questionnaire (HAQ), short-form 36 (SF-36), pain, fatigue, patient global assessment of disease activity, self-efficacy scales, rheumatoid arthritis disease activity index (RADAI), and SF-6D utility. Patients stated consultations with the multidisciplinary team.

Results

Improvements were short-lived, and at 6 months follow-up period only mental health, pain and utility remained improved with small effect sizes. Extensive involvement of health professionals was not associated with improved outcomes.

Conclusions

Patients with inflammatory rheumatic disease receiving inpatient multidisciplinary rehabilitation had small and mainly short-term improvements in most PROs. High use of the multidisciplinary team did not enhance or preserve rehabilitation outcomes in inflammatory rheumatic conditions when admitted as inpatients.

Adding Genetic Testing to Evidence-Based Guidelines to Determine the Safest and Most Effective Chronic Pain Treatment for Injured Workers

Published guidelines for treating injured workers include the need for personalized treatment to manage chronic pain symptoms and increase functional status. However, they often fail to clarify how to objectively personalize these treatments. Further, certain patients need analgesic relief beyond the short term. In these cases, it is not sufficient or reasonable to utilize the typical broad protocol-based justifications for reduction of opioids and other medications in a haphazard manner based purely on poor response, without attempting to elucidate possible pharmacogenetic reasons for this. These guidelines acknowledge the problem of substance abuse and set forth methods for treatment and prevention. Although it has been established in the scientific community that an individual's experience of pain and likelihood for addiction both have genetic components, genetic testing is not routinely included as part of the overall treatment plan for injured workers with chronic pain. Because decisions in cases of workplace injury should be based on scientific evidence, genetic testing results can add some objective information to the existing subjective and objective clinical data; help ascertain the efficacy and potential for toxicity of treatment; and therefore provide more information for accurate clinical decisions. We propose the addition of genetic testing to consensus guidelines for treating injured workers in order to improve patients' functional status, increase productivity, improve safety of prescribing, decrease the likelihood of substance abuse, and save on overall healthcare costs.
