Treat-to-target fixed dose rituximab retreatment versus fixed interval retreatment with disease activity-guided rituximab dose optimisation for patients with rheumatoid arthritis: study protocol for a multicentre randomised controlled superiority trial focusing on long-term disease impact (RITUXERA)

BACKGROUND

The optimal retreatment strategy with rituximab for rheumatoid arthritis (RA) remains a point of discussion. Depending on local guidelines, rituximab can either be administered at fixed intervals or when losing disease control, balancing therapeutic effectiveness with drug overexposure. However, treatment based on loss of disease control may significantly affect patients' lives, provoking uncertainty and potentially leading to progressive joint damage. Moreover, as low-dose rituximab proved to be effective in treating RA while decreasing toxicity, drug exposure may be limited by tapering down rituximab doses guided by disease activity.

METHODS

RITUXERA is a 104-week open-label multicentre randomised controlled superiority trial. In total, 134 patients with RA treated with rituximab will be 1:1 randomised when in need of retreatment (DAS28-CRP ≥ 3.2 with previous rituximab administration at least 24 weeks earlier) to either a treat-to-target-driven fixed dose retreatment strategy (usual care group) or fixed interval disease-activity guided dose optimisation strategy (experimental group). The usual care group will be retreated with fixed rituximab doses (1 × 1000 mg IV) in case of loss of disease control (DAS28-CRP ≥ 3.2). The experimental group will receive a 24-weekly rituximab treatment while tapering down the dose in a decreasing sequence if DAS28-CRP ≤ 3.2: 1 × 1000 mg IV (maximal dose), 1 × 500 mg IV, and 1 × 200 mg IV (minimal dose). If DAS28-CRP exceeds 3.2 at the six-monthly retreatment, patients will receive and remain on the previous effective dose. Study visits are planned every 12 weeks. Primary outcome is the comparison of longitudinal patient-reported disease impact over 104 weeks, measured with the Rheumatoid Arthritis Impact of Disease (RAID) instrument, analysed using a linear mixed model. Main secondary outcome is the comparison of longitudinal disease activity (DAS28-CRP) over 104 weeks.

DISCUSSION

The RITUXERA trial aims to explore the optimal retreatment strategy with rituximab for RA in terms of long-term patient-reported disease impact, by proposing a fixed interval disease activity-guided dose optimisation strategy as compared to a treat-to-target fixed dose strategy.

Efficacy of a cognitive-behavioral digital therapeutic on psychosocial outcomes in rheumatoid arthritis: randomized controlled trial

Cognitive behavioral therapy improves psychosocial outcomes in rheumatoid arthritis (RA), but access is limited. We conducted a randomized controlled trial to evaluate the efficacy of a cognitive-behavioral digital therapeutic, reclarit, on psychosocial outcomes in adult RA patients with impaired health-related quality of life. Participants were randomized to reclarit plus treatment as usual (TAU) or TAU plus educational and informational material (active control). The primary outcome was SF-36 mental (MCS) and physical (PCS) component summary scores at 3 months, with additional assessments at 6 months. reclarit significantly improved SF-36 MCS scores compared to control (mean difference 3.3 [95% CI 0.7, 5.9]; p = 0.014), with high user satisfaction and sustained improvements at 6 months. Depression, anxiety, fatigue, and social/work functioning also improved significantly, while SF-36 PCS, pain, and disability scores did not differ. In conclusion, reclarit offers immediate, effective, evidence-based and personalized psychological support for RA patients.

Effectiveness and feasibility of a mobile health self-management intervention in rheumatoid arthritis: study protocol for a pragmatic multicentre randomised controlled trial (AEGORA)

BACKGROUND

Rheumatoid arthritis (RA) considerably impacts patients' lives. Patients' confidence in their ability to manage this impact, or self-efficacy, can be supported with self-management interventions. One approach is to use mobile health (mHealth) applications, which can additionally provide insight into disease impact by remotely monitoring patient-reported outcomes. However, user engagement with mHealth-apps is variable, and concerns exist that remote monitoring might make patients overly attentive to symptoms.

METHODS

App-based Education and GOal setting in RA (AEGORA) is a multicentre, pragmatic randomised controlled trial investigating an mHealth-based self-management intervention to improve self-efficacy and remotely monitor disease impact in patients with RA. The intervention is provided via an adapted version of the application Sidekick (Sidekick Health, Reykjavik, Iceland) and consists of education, goal setting, lifestyle advice, and remote assessment of the Rheumatoid Arthritis Impact of Disease (RAID) questionnaire. Across two centres, 120 patients will be recruited and randomised (2:1:1) to usual care or intervention group A/B (study app with weekly/monthly prompts to complete the RAID, respectively). Outcomes are assessed at baseline and after 4-6 months. The primary endpoint is a clinically important improvement (≥ 5.5/110) in the Arthritis Self-Efficacy Scale in the combined intervention group compared to usual care. Secondary endpoints are (a) non-inferiority regarding pain catastrophising, as a measure of symptom hypervigilance; (b) superiority regarding the RAID, sleep quality, and physical activity; and (c) participant engagement with the study app. Finally, the relationship between engagement, prompted frequency of RAID questionnaires, and the primary and secondary outcomes will be explored.

DISCUSSION

The AEGORA trial aims to study the effectiveness of mHealth-based, multicomponent self-management support to improve self-efficacy in the context of RA, while providing potentially valuable insights into temporal disease activity dynamics and the feasibility and possible negative effects of remote symptom monitoring in this population.

Nonpharmacological approaches for pain and symptoms of depression in people with osteoarthritis: systematic review and meta-analyses

People with osteoarthritis often experience pain and depression. These meta-analyses examined and compared nonpharmacological randomized controlled trials (RCTs) for pain and symptoms of depression in people living with osteoarthritis. RCTs published up until April 2022 were sourced by searching electronic databases EMBASE, PUBMED & MEDLINE, Web of Science, CINAHL and PEDro. Random-effects meta-analyses were performed to calculate pooled effect sizes (ES) and 95% confidence intervals (CI) for pain and depression. Subgroup analyses examined intervention subtypes. For pain, 29 interventions (n = 4382; 65 ± 6.9 years; 70% female), revealed a significant effect on reducing pain (ES = 0.43, 95% CI [0.25, 0.61], p < 0.001). Effect sizes were significant (p < 0.001) for movement meditation (ES = 0.52; 95% CI [0.35, 0.69]), multimodal approaches (ES = 0.37; 95% CI [0.22, 0.51]), and psychological therapy (ES = 0.21; 95% CI [0.11, 0.31]), and significant (p = 0.046) for resistance exercise (ES = 0.43, 95% CI [- 0.07, 0.94]. Aerobic exercise alone did not improve pain. For depression, 28 interventions (n = 3377; 63 ± 7.0 years; 69% female), revealed a significant effect on reducing depressive symptoms (ES = 0.29, 95% CI [0.08, 0.49], p < 0.001). Effect sizes were significant for movement meditation (ES = 0.30; 95% CI [0.06, 0.55], p = 0.008) and multimodal interventions (ES = 0.12; 95% CI [0.07, 0.18], p < 0.001). Resistance/aerobic exercise or therapy alone did not improve depressive symptoms. Mind-body approaches were more effective than aerobic/resistance exercise or therapy alone for reducing pain and depression in people with osteoarthritis.Systematic review registration: PROSPERO CRD42022338051.

Treatment response and several patient-reported outcomes are early determinants of future self-efficacy in rheumatoid arthritis

BACKGROUND

Self-efficacy, or patients' confidence in their ability to control disease and its consequences, was recently prioritised in EULAR recommendations for inflammatory arthritis self-management strategies. However, it remains unclear which factors influence self-efficacy in early rheumatoid arthritis (RA).

METHODS

Data were analysed from the 2-year RCT Care in early RA (CareRA), which studied remission-induction treatment regimens for early RA. Participants completed the Arthritis Self-Efficacy Scale (ASES), Short-Form 36 (SF-36), Revised Illness Perception Questionnaire (IPQ-R), Utrecht Coping List (UCL), RAQoL and Health Assessment Questionnaire (HAQ). Depending on time to first remission (DAS28-CRP < 2.6) and persistence of remission, treatment response was defined as persistent response, secondary failure, delayed response, late response or non-response. The association between ASES scores and clinical/psychosocial factors was explored with Spearman correlation and multivariate linear mixed models. Baseline predictors of week 104 ASES were identified with exploratory linear regression followed by multiple regression of significant predictors adjusted for DAS28-CRP, HAQ, treatment arm, treatment response, cumulative CRP/SJC28 and demographic/serologic confounders.

RESULTS

All 379 patients had a recent diagnosis of RA and were DMARD-naïve at study initiation. Most patients were women (69%) and RF/ACPA-positive (66%), and the mean (SD) age was 52 (13) years. For all tested outcome measures, better perceived health correlated with higher self-efficacy. While patient-reported factors (HAQ, SF-36, RAQoL, IPQ-R, pain, fatigue and patient's global assessment) showed moderate/strong correlations with ASES scores, correlations with physician-reported factors (physician's global assessment, SJC28), TJC28 and DAS28-CRP were weak. Only more favourable outcomes on patient-reported factors and DAS28-CRP were associated with higher ASES scores at each time point. An earlier, persistent treatment response predicted higher ASES scores at both weeks 52 and 104. Significant baseline predictors of week 104 ASES included HAQ; SF-36 mental component score, vitality, mental health and role emotional; IPQ-R illness coherence, treatment control, emotional representations and consequences; UCL Passive reacting; and the RAQoL.

CONCLUSIONS

Patient-reported outcomes and treatment response were early determinants of long-term self-efficacy in an early RA trial. These results provide further relevance for the window of opportunity in an early treat-to-target strategy and could help to timely identify patients who might benefit from self-management interventions.

Tele-health interventions to support self-management in adults with rheumatoid arthritis: a systematic review

Rheumatoid arthritis (RA), a long-term auto-immune condition is a challenging condition for patients to manage. Goals of treatment include reducing pain, decreasing inflammation, and improving an individual's overall function. Increasingly technology is being utilised to support patients to self-manage their condition. The aim of this systematic narrative review was to synthesise and critically appraise published evidence concerning the effectiveness of tele-health interventions to support self-management in RA. Bibliographic databases searched from 2014 to March 2020 included MedLINE, Embase, Cochrane Library. Search strategy combined the following concepts: (1) rheumatoid arthritis, (2) tele-health interventions, and (3) self-management. Only randomised controlled trials (RCTs) involving adults with RA were included. Titles, abstracts, full-text articles were screened, any discrepancies were checked by a second reviewer. Risk of bias was assessed using Cochrane risk of bias tool and data were extracted utilising the Cochrane data collection form for RCT interventions along with the TiDier checklist. Due to high heterogeneity, results were not meta-analysed and instead data were synthesised narratively. The search identified 98 articles, seven were included. The completed RCTs varied in the nature of the interventions, duration/severity of RA, outcomes measured and effectiveness of the interventions. The completed RCTs included a total of 791 participants Disease duration was largely between 4 and 10 years and disease severity on average was moderate. There was extensive variation in intervention components, theories underpinning theories and outcomes measured. Five RCTs reported a positive effect on factors such as disease activity, medication adherence, physical activity and self-efficacy levels. This study suggests that tele-health interventions that are well-designed, tailored and multi-faceted can help to achieve positive self-management outcomes in RA. None of the studies showed evidence of harm.

Identification of Tools for the Functional and Subjective Assessment of Patients in an Aquatic Environment: A Systematic Review

Aquatic therapy is one of the most common treatments for alleviating musculoskeletal pathologies. Its effectiveness has been evaluated with functional tests and questionnaires. Functional tests are used in aquatic therapy; however, in most cases, they are carried out in a non-aquatic environment and, as such, their results may differ from those of tests performed in an aquatic environment. A systematic review was performed to assess the accuracy of functional tests and patient-reported outcomes to assess aquatic therapy interventions. The authors conducted a literature search in July 2019. In total, 70,863 records were identified after duplicates removed. Of these, 14 records were included about functional tests assessment in aquatic environment and 725 records for questionnaires. The majority of the tests had also been assessed in a dry environment, allowing differences and similarities between the tests in the two environments to be observed. Different variables have been assessed in tests included in the present systematic review (cardiorespiratory, neuromuscular, kinematic, physiological, kinetic responses and rating of perceived exertion) which are included in the manuscript. Visual Analogue Scale, Western Ontario and McMaster Universities Osteoarthritis Index and the 12-item Short Form Health Survey were the assessments most commonly used by the different authors.

Translation to Brazilian Portuguese, cultural adaptation and psychometric properties of 8-item ArthritisSelf-Efficacy Scale (ASES-8)

BACKGROUND

Self-efficacy refers to one's belief in one's ability to organize, perform actions and face challenges in order to achieve goals and motivation. High self-efficacy improves disease coping and adherence to treatment among patients with rheumatoid arthritis. The objective of this study was to translate, culturally adapt and test the reproducibility of the 8-item Arthritis Self-Efficacy Scale (ASES-8) questionnaire for use in Brazil.

DESIGN AND SETTING

Validation study conducted in university outpatient clinics.

METHODS

The questionnaire was translated into Brazilian Portuguese and then back-translated into English. The final version in Portuguese was tested on 30 patients with rheumatoid arthritis and was shown to be understandable and culturally adapted. A further 32 patients with rheumatoid arthritis were evaluated three times using the questionnaire. On the first occasion, two evaluators applied the questionnaire to check inter-evaluator reproducibility. After 15 days, one of the evaluators reassessed the patients to verify intra-evaluator reproducibility. At the first assessment, to test the construct validity of ASES-8, the Numerical Pain Scale, Health Assessment Questionnaire, Beck Depression Inventory and Short Form-36 questionnaire were also applied to all the patients.

RESULTS

The inter and intra-evaluator correlation coefficients for ASES-8 were high. Cronbach's alpha was higher than 0.90 for the questionnaire, indicating excellent internal consistency. There were moderate correlations between ASES-8 and most of the instruments tested, indicating good construct validity.

CONCLUSION

ASES-8 was translated and adapted to the Portuguese language for Brazil. This instrument is valid, reproducible and reliable for evaluating self-efficacy among patients with rheumatoid arthritis.

French validation of the Arthritis Self-Efficacy Scale and further psychometric properties exploration among 168 people with osteoarthritis

Objective:

To validate the Arthritis Self-Efficacy Scale—French version (ASES-F) of the ASES questionnaire designed to evaluate self-efficacy in arthritis population and to confirm its psychometric properties.

Design:

The translation/back-translation procedure was done in line with cross-cultural adaptation international guidelines. Prospective multicenter validation was performed on 168 patients with osteoarthritis who filled out the ASES-F. Function subscale of the Western Ontario and McMaster Universities Arthritis Index, Hospital Anxiety and Depression (HAD), Knee Osteoarthritis Fears and Beliefs Questionnaire, and pain on visual analog scale were collected. Acceptability, internal consistency, reproducibility, internal and external structure validity, and sensitivity following a self-management program focused on physical activity were analyzed. The retest was performed 15 days later.

Results:

A culturally adapted version was obtained following the validation procedure. The final translated questionnaire is available within the full article. Cronbach’s alpha coefficient was at 0.95 for the overall ASES-F. Regarding the test–retest reproducibility, Lin’s concordance coefficient was at 0.84. The internal and external validity was also explored with correlations at −0.50 between ASES-F and (WOMAC), and significant correlations between ASES-F and HAD. Sensitivity shown significant improvement at three months for the subscale function only (+2.65, P < 0.01).

Conclusion:

The ASES-F, French version of the ASES, available in supplemental data, was validated in knee osteoarthritis patients and could be used in clinical practice and research for French-speaking patients. Sensitivity needs to be more explored.

A systematic review of outcome measures utilised to assess self-management in clinical trials in patients with chronic pain

OBJECTIVES

The aim of this review was to identify, appraise and synthesise the outcome measures used to assess self-management in patients with chronic pain.

METHODS

Medline, Embase, CINAHL, PsycINFO, the Cochrane Library and Google Scholar were searched to identify quantitative measures used within randomised or non-randomised clinical trials to assess self-management in adults (≥18 years) with chronic pain.

RESULTS

25 RCTs published between 1998 and 2016 were included in this review. Studies included patients with chronic pain, hip/knee osteoarthritis, rheumatoid arthritis, chronic low back pain, fibromyalgia and chronic fatigue syndrome. Included studies utilised 14 different measures assessing a variety of constructs including self-efficacy (n = 19), coping (n = 4), empowerment (n = 2), pain attitude and management (n = 3), self-care (n = 1), role behaviour (n = 1) and multiple constructs of self-management (n = 1). The Chronic Pain Coping Inventory (CPCI) and Health Education Impact Questionnaire (heiQ) cover different self-management related constructs across the physical, mental and social health domains.

CONCLUSION

The review identified 14 measures used as proxy measure to assess self-management in patients with chronic pain. These measures have good content and construct validity, and internal consistency. However additional research is required to develop their reliability, responsiveness and interpretability.

PRACTICE IMPLICATIONS

Multi-constructs measures (CPCI, heiQ) are suitable for assessing self-management.

A single-blinded, randomized, parallel group superiority trial investigating the effects of footwear and custom foot orthoses versus footwear alone in individuals with patellofemoral joint osteoarthritis: a phase II pilot trial protocol

BACKGROUND

Patellofemoral joint osteoarthritis is a common condition, yet information regarding conservative management is lacking. Foot orthoses are an effective intervention for improving pain and function in younger individuals with patellofemoral pain and may be effective in those with patellofemoral osteoarthritis. This pilot study will seek to establish the feasibility of a phase III randomised controlled trial to investigate whether foot orthoses worn in prescribed motion controlled footwear are superior to prescribed motion control footwear alone in the management of patellofemoral osteoarthritis.

METHODS/DESIGN

This phase II pilot clinical trial is designed as a randomized, single-blind, parallel group, two arm, superiority trial. The trial will recruit 44 participants from Queensland and Tasmania, Australia. Volunteers aged 40 years and over must have clinical symptoms and radiographic evidence of patellofemoral osteoarthritis to be eligible for inclusion. Those eligible will be randomized to receive either foot orthoses and prescribed motion control shoes, or prescribed motion control shoes alone, to be worn for a period of 4 months. The feasibility of a phase III clinical trial will be evaluated by assessing factors such as recruitment rate, number of eligible participants, participant compliance with the study protocol, adverse events, and drop-out rate. A secondary aim of the study will be to determine completion rates and calculate effect sizes for patient reported outcome measures such as knee-related symptoms, function, quality of life, kinesiophobia, self-efficacy, general and mental health, and physical activity at 2 and 4 months. Primary outcomes will be reported descriptively while effect sizes and 95% confidence intervals will be calculated for the secondary outcome measures. Data will be analysed using an intention-to-treat principle.

DISCUSSION

The results of this pilot trial will help determine the feasibility of a phase III clinical trial investigating whether foot orthoses plus motion control footwear are superior to motion control footwear alone in individuals with patellofemoral osteoarthritis. A Phase III clinical trial will help guide footwear and foot orthoses recommendations in the clinical management of this disorder.

Improving the self-management of chronic pain: COping with persistent Pain, Effectiveness Research in Self-management (COPERS)

Background

Chronic musculoskeletal pain is a common problem that is difficult to treat. Self-management support interventions may help people to manage this condition better; however, there is limited evidence showing that they improve clinical outcomes. Our overarching research question was ‘Does a self-management support programme improve outcomes for people living with chronic musculoskeletal pain?’.

Aim

To develop, evaluate and test the clinical effectiveness and cost-effectiveness of a theoretically grounded self-management support intervention for people living with chronic musculoskeletal pain.

Methods

In phase 1 we carried out two systematic reviews to synthesise the evidence base for self-management course content and delivery styles likely to help those with chronic pain. We also considered the psychological theories that might underpin behaviour change and pain management principles. Informed by these data we developed the Coping with persistent Pain, Evaluation Research in Self-management (COPERS) intervention, a group intervention delivered over 3 days with a top-up session after 2 weeks. It was led by two trained facilitators: a health-care professional and a layperson with experience of chronic pain. To ensure that we measured the most appropriate outcomes we reviewed the literature on potential outcome domains and measures and consulted widely with patients, tutors and experts. In a feasibility study we demonstrated that we could deliver the COPERS intervention in English and, to increase the generalisability of our findings, also in Sylheti for the Bangladeshi community. In phase 2 we ran a randomised controlled trial to test the clinical effectiveness and cost-effectiveness of adding the COPERS intervention to a best usual care package (usual care plus a relaxation CD and a pain toolkit leaflet). We recruited adults with chronic musculoskeletal pain largely from primary care and musculoskeletal physiotherapy services in two localities: east London and Coventry/Warwickshire. We collected follow-up data at 12 weeks (self-efficacy only) and 6 and 12 months. Our primary outcome was pain-related disability (Chronic Pain Grade disability subscale) at 12 months. We also measured costs, health utility (European Quality of Life-5 Dimensions), anxiety, depression [Hospital Anxiety and Depression Scale (HADS)], coping, pain acceptance and social integration. Data on the use of NHS services by participants were extracted from NHS electronic records.

Results

We recruited 703 participants with a mean age of 60 years (range 19–94 years); 81% were white and 67% were female. Depression and anxiety symptoms were common, with mean HADS depression and anxiety scores of 7.4 [standard deviation (SD) 4.1] and 9.2 (SD 4.6), respectively. Intervention participants received 85% of the course content. At 12 months there was no difference between treatment groups in our primary outcome of pain-related disability [difference –1.0 intervention vs. control, 95% confidence interval (CI) –4.9 to 3.0]. However, self-efficacy, anxiety, depression, pain acceptance and social integration all improved more in the intervention group at 6 months. At 1 year these differences remained for depression (–0.7, 95% CI –1.2 to –0.2) and social integration (0.8, 95% CI, 0.4 to 1.2). The COPERS intervention had a high probability (87%) of being cost-effective compared with usual care at a threshold of £30,000 per quality-adjusted life-year.

Conclusions

Although the COPERS intervention did not affect our primary outcome of pain-related disability, it improved psychological well-being and is likely to be cost-effective according to current National Institute for Health and Care Excellence criteria. The COPERS intervention could be used as a substitute for less well-evidenced (and more expensive) pain self-management programmes. Effective interventions to improve hard outcomes in chronic pain patients, such as disability, are still needed.

Community patient education and exercise for people with fibromyalgia: a parallel group randomized controlled trial

Objective: To evaluate the effects of a community patient education -exercise programme, using a cognitive-behavioural approach, for people with fibromyalgia.

Design: A randomized, parallel group trial with assessments at 0, 4 and 8 months.

Setting: Community leisure centres.

Subjects: People with fibromyalgia ( n=183) attending a rheumatology outpatient department at a large district general hospital.

Interventions: Participants were randomized to a patient education-exercise group ( n=97) or relaxation (attention control) group ( n=86).

Main measures: The Fibromyalgia Impact Questionnaire (0-80; lower score means better health). Secondary outcomes included: the Arthritis Self-Efficacy Scale(pain and other symptoms subscales: 1 -10 scale; higher scores mean greater self-efficacy) and self-reported improvement.

Results: Fifty participants withdrew or were unable to attend and 133 completed and returned baseline questionnaires: patient education group ( n=71); relaxation group ( n=62); 120/133 participants were women. Average age was 48. 53 (SD 10.89) years. Follow-up ranged between 73 and 82% of questionnaires returned. At four months, there was a difference in average changes in total Fibromyalgia ImpactQuestionnaire scores between the two groups: patient education group -3.38 (SD 9.35); relaxation group 0.3 (SD 8.85); P=0.02. Arthritis Self-Efficacy Scale scores were significantly higher in the patient education group: pain 0.59 (SD 1.45)compared to the relaxation group’s -0.12 (SD 1.22); P=0.003; other symptoms (patient education group 0.72 (SD 1.33); relaxation group 0.03 (SD 1.16); P=0.002). At eight months these differences were no longer apparent. Forty-seven per cent in the patient education group self-reported improvement compared with 13% in the relaxation group (ϰ=13.65; P=0.0001).

Conclusion: Short-term improvements resulted from the education -exercise programme but were not sustained. Appropriate selection may improve efficacy.

Rasch analysis of the Norwegian version of the Arthritis Self-Efficacy Scale (ASES)

OBJECTIVES

To apply the Rasch model to the Norwegian version of the Arthritis Self-Efficacy Scale (ASES).

METHOD

The ASES was included in a self-administered questionnaire sent to 224 patients attending one of three rehabilitation centres for rheumatic diseases in Norway in 2009. The fit of the ASES to the Rasch model was assessed together with hypothesized associations with the Modified Health Assessment Questionnaire (MHAQ), the 36-item Short Form Health Survey (SF-36), the numerical rating scale (NRS) for pain, and NRS fatigue.

RESULTS

A total of 145 (64.7%) patients responded to the questionnaire. The two scales of other symptoms and pain showed good fit to the Rasch model with no evidence for differential item functioning (DIF) according to eight sociodemographic and disease-related variables. The Person Separation Index (PSI), which is equivalent to Cronbach's alpha, ranged from 0.74 to 0.78. Correlations with scores for other instruments were as hypothesized: ASES pain had the highest correlations with SF-36 pain and NRS pain and ASES other symptoms had the highest correlations with other aspects of the SF-36 and NRS fatigue.

CONCLUSIONS

The ASES had good fit to the Rasch model and correlations with other instrument scores that followed hypotheses, lending further support to the application of the instrument in patients with rheumatic diseases.

Effects of needs-based patient education on self-efficacy and health outcomes in people with rheumatoid arthritis: a multicentre, single blind, randomised controlled trial

Objectives

The Educational Needs Assessment Tool (ENAT) is a self-completed questionnaire, which allows patients with arthritis to prioritise their educational needs. The aim of this study was to evaluate the effects of needs-based patient education on self-efficacy, health outcomes and patient knowledge in people with rheumatoid arthritis (RA).

Methods

Patients with RA were enrolled into this multicentre, single-blind, parallel-group, pragmatic randomised controlled trial. Patients were randomised to either the intervention group (IG) where patients completed ENAT, responses of which were used by the clinical nurse specialist to guide patient education; or control group (CG) in which they received patient education without the use of ENAT. Patients were seen at weeks 0, 16 and 32. The primary outcome was self-efficacy (Arthritis Self Efficacy Scale (ASES)-Pain and ASES-Other symptoms). Secondary outcomes were health status (short form of Arthritis Impact Measurement Scale 2, AIMS2-SF) and patient knowledge questionnaire-RA. We investigated between-group differences using analysis of covariance, adjusting for baseline variables.

Results

A total of 132 patients were recruited (IG=70 and CG=62). Their mean (SD) age was 54 (12.3) years, 56 (13.3)  years and disease duration 5.2 (4.9) years, 6.7 (8.9) years for IG and CG, respectively. There were significant between-group differences, in favour of IG at week 32 in the primary outcomes, ASES-Pain, mean difference (95% CI) −4.36 (1.17 to 7.55), t=−2.72, p=0.008 and ASES-Other symptoms, mean difference (95% CI) −5.84 (2.07 to 9.62), t=−3.07, p=0.003. In secondary outcomes, the between-group differences favoured IG in AIMS2-SF Symptoms and AIMS2-SF Affect. There were no between-group differences in other secondary outcomes.

Conclusions

The results suggest that needs-based education helps improve patients’ self-efficacy and some aspects of health status.

Psychometric Properties of the Coping Self-Efficacy Scale Among HIV-Infected Iranian Patients

BACKGROUND

Self-efficacy is an important predicator of coping with stress.

OBJECTIVES

This study aimed to determine the psychometric characteristics of the coping self-efficacy (CSE) scale among HIV-infected Iranian patients.

PATIENTS AND METHODS

Psychometric properties of the CSE scale were examined by using a cross-sectional study design. One hundred and twenty HIV-infected Iranian patients that had been referred to the Counseling of Behavioral Diseases Center at Imam Khomeini Hospital in Tehran, Iran in 2014 were selected through simple random sampling method. To determine the Content Validity Index (CVI) and the content validity ratio (CVR), a panel of experts (n = 20) reviewed items of CSE scale. Reliability was estimated through the internal consistency (n = 30) and the conformity factor analysis was performed.

RESULTS

Iranian version of the CSE scale contained 16 items, including 7 items on the "use of problem-focused coping" method, 5 items on "stopping unpleasant emotions and thoughts", and 4 items on "getting support from friends and family". CVI and CVR scores were 0.79, 0.42 and more, respectively. Internal consistencies (range, 0.64 to 0.84) of 3 subscales were acceptable. Confirmatory factor analysis showed that comparative indices of the model, including CFI, IFI, GFI, RMSEA, and Chi-square (χ2/df) were 0.96, 0.95, 0.84, 0.83, and 1.82, respectively, which indicated a good fit for the data.

CONCLUSIONS

The Iranian version of the CSE scale is a valid instrument to measure the coping self-efficacy among people living with HIV in research and community settings in Iran.

Self-efficacy as an appraisal that moderates the coping-emotion relationship: associations among people with rheumatoid arthritis

The way a coping strategy is expressed might depend on the nature of underlying efficacy expectations. For example, a cognitive coping strategy may have different content depending on efficacy beliefs underpinning the strategy's formulation and application. As such, self-efficacy (SE), as an appraisal, may moderate relationships between coping and outcomes: coping effects may differ depending on SE. This process was examined in 127 rheumatoid arthritis patients attending routine patient education/self-management programmes. Participants completed questionnaire measures of SE, coping, anxiety and depression at baseline and at 8 weeks follow-up. Regression analyses focused on coping and SE change variables, and their concurrent association with measures of change in anxiety and depression. Results highlighted contributions to these emotional variables from interactions between coping and SE. The nature of associations between coping and emotional outcomes was found to differ according to efficacy appraisals. This may have implications for clinical practice in that the adaptive significance of adjustment efforts may differ according to underlying SE.

A Meta-Synthesis of Health-Related Self-Efficacy Instrumentation: Problems and Suggestions

Background and Purpose: Self-efficacy, a central construct in health interventions, has been measured in various contexts. The absence of any published meta-review of self-efficacy instrumentation led to the current meta-synthesis that reports and evaluates the instrumentation processes. Methods: A systematic search resulted in 39 self-efficacy instrumentation studies, which were evaluated for the aspects of conceptual bases, health contexts, operational definition, instrumentation procedures, reliability and scale length, and item content. Results: Primarily based in Bandura’s social cognitive theory, these studies reported self-efficacy instrumentation for developing new scales and modifying/validating measures for illness management, healthy behavior adoption/maintenance, disease/risk prevention, and aging management. Trait-like, specific-domain, and situation approaches were used for generating item content. Problems in some studies include non-efficacy items, a lack of systematic instrumentation procedures, item content too general for specific-domain self-efficacy, and measurement inefficiency. Conclusions: The piecemeal fashion of self-efficacy instrumentation has resulted in incomparable self-efficacy measures of similar domains of health functioning. A trans-domain framework, thus, is warranted. Suggestions are provided for solving other problems in self-efficacy instrumentation.

Measurement properties of instruments assessing self-efficacy in patients with rheumatic diseases

The measurement properties of instruments assessing self-efficacy (SE) in patients with rheumatic diseases were reviewed. The consensus-based standards for the selection of health measurement instruments (COSMIN) checklist was applied following systematic searches of seven electronic databases from 1989 to December 2011. Fifteen articles met the inclusion criteria that included the arthritis SE scales (ASES), generalized SE scale (GSES), joint protection SE scale (JP-SES), Marcus & Resnick SE exercise behaviour (SEEB) instruments, and RA SE scale (RASE). The ASES and RASE have undergone more than one evaluation. There was little formal evaluation of content validity for the instruments. Evidence for the RASE suggests that it is not unidimensional. The JP-SES and SEEB were evaluated using modern psychometric methods. The instruments require further evaluation before application. The quality of the evidence for the ASES and RASE is generally poor. The generic focus of the GSES limits its relevance. The JP-SES and SEEB have only undergone one evaluation and that relating to the latter was narrow in scope. Future studies should address these methodological weaknesses.

The impact on self-efficacy of different types of follow-up care and disease status in patients with rheumatoid arthritis--a randomized trial

OBJECTIVE

To explore the impact from different types of outpatient care, demographic and disease related variables on self-efficacy beliefs (SE) in patients with established rheumatoid arthritis (RA) after completing an educational program.

METHODS

287 adult RA outpatients with low disease activity and moderate physical disability from two Danish rheumatology clinics were randomized for follow-up care. (1) planned rheumatologist's consultations, (2) a shared care model without planned consultations, (3) planned nursing consultations. The participants' SE were assessed by the Danish versions of the rheumatoid arthritis self-efficacy questionnaire (RASE) and the arthritis self-efficacy scale (ASES). Data were collected at baseline, 3 months and one-year follow up and were explored in random intercept models.

RESULTS

Following an educational programme the nursing group increased or stabilized their SE during the first year compared to the medical and the shared care group. SE in the shared care group did not differ significantly from the medical group. No difference between the groups was seen in disease activity at any time.

CONCLUSION

Nursing consultations provide opportunities for maintenance of the patients' SE after patient education.

PRACTICE IMPLICATIONS

Implementation of nursing consultations as part of follow-up care in patients with stable RA is recommended.

Self-efficacy as an outcome measure and its association with physical disease-related variables in persons with rheumatoid arthritis: a literature review

BACKGROUND

Studies have demonstrated a positive impact of patient education on self-efficacy in persons with rheumatoid arthritis (RA). However, the relationship between self-efficacy, physical disease-related variables and educational interventions has not yet been reviewed.

AIM

The aims of this study, in relation to persons with RA, were: 1) to provide an overview of the existing research into the association between self-efficacy and physical disease-related variables and, with this knowledge, 2) to provide an overview of the existing research on the effect of different types of educational interventions on self-efficacy.

METHOD

A systematic literature search was performed using eight databases, based on the terms 'rheumatoid arthritis' AND 'self-efficacy'. In total, 74 studies reporting associations between self-efficacy and physical disease-related variables and using self-efficacy as an outcome measure in educational interventions were included.

RESULTS

The scores obtained by the most commonly used questionnaire, the Arthritis Self-Efficacy Scale (ASES), was highly associated with physical disability, pain, fatigue and disease duration. If educational activities had a positive impact on self-efficacy, disease-related variables usually improved as well. Evidence is scarce as to whether disease-related variables affect patients' self-efficacy or vice versa and whether individual consultations can affect patients' self-efficacy.

CONCLUSION

The scores attained by the ASES is highly associated with physical disease-related variables. This relationship requires further research using a specific study design to restrict bias when evaluating the impact of interventions on self-efficacy in persons with RA. Research is needed on whether individual consultations can affect patients' self-efficacy. Disease-related variables do not affect the Rheumatoid Arthritis Self-Efficacy (RASE) questionnaire but this needs further exploration.

Self-efficacy in rheumatoid arthritis: translation and test of validity, reliability and sensitivity of the Danish version of the Rheumatoid Arthritis Self-Efficacy Questionnaire (RASE)

OBJECTIVES

To describe the translation and test of the Danish version of the original British 'Rheumatoid Arthritis Self-Efficacy Questionnaire' (RASE).

METHODS

The questionnaire was forward and back translated by individuals with Danish and English as their respective primary languages. The questionnaire was tested by five lay-people and in the field by 10 + five persons with rheumatoid arthritis (RA). A test-retest was performed on 62 outpatients with RA. The sensitivity of the adapted Danish version of RASE (RASE-DK) was finally tested on 106 outpatients with RA - before, immediately after and three months after they had participated in a short self-management course performed by a multidisciplinary team.

RESULTS

RASE-DK showed good face validity, but 'relaxation' was interpreted in various ways. Internal consistency evaluated by Cronbach's alpha was 0.91. Reliability evaluated by the intra-class correlation coefficient (ICC) was 0.88. A Bland-Altman plot showed good agreement. RASE-DK, like the original English version of RASE, was not associated with disease activity (Disease Activity Score, DAS-28) or disability (Health Assessment Questionnaire, HAQ), and correlated significantly with the Arthritis Self-Efficacy Scale (ASES) subscales 'other' and 'pain', and total ASES. RASE-DK showed a highly significant change, from baseline to immediately after participation in the short course (p < 0.001). The effect faded during the following three months.

CONCLUSION

RASE-DK met the appropriate standards for validity, reliability and sensitivity, and is appropriate for use in Denmark. However, the concept of self-efficacy may be too abstract for a few individuals, and relaxation is interpreted in various ways by the Danish patients.

Disease severity and domain-specific arthritis self-efficacy: relationships to pain and functioning in patients with rheumatoid arthritis

OBJECTIVE

To examine the degree to which disease severity and domains of self-efficacy (pain, function, and other symptoms) explain pain and functioning in rheumatoid arthritis (RA) patients.

METHODS

Patients (n = 263) completed the Arthritis Impact Measurement Scales 2 to assess pain and functioning (physical, affective, and social), the Arthritis Self-Efficacy Scale to assess 3 self-efficacy domains (pain, physical function, and other). Disease severity was assessed with C-reactive protein level, physician's rating, and abnormal joint count. Structural equation modeling was used to examine 3 hypotheses: does disease severity have a direct relationship with pain and each area of functioning, does disease severity have a direct relationship with each arthritis self-efficacy domain, and do the self-efficacy domains mediate the relationship between disease severity and RA pain and each area of functioning.

RESULTS

Disease severity was related to pain, physical functioning, and each self-efficacy domain (beta = 0.28-0.56, P < 0.001). Each self-efficacy domain was related to its respective domain of functioning (e.g., self-efficacy for pain was related to pain; beta = 0.36-0.54, P < 0.001). Self-efficacy mediated the relationship between disease severity and pain and functioning (beta = 0.12-0.19, P < 0.001). Self-efficacy for pain control and to perform functional tasks accounted for 32-42% of disease severity's total effect on their respective outcomes (e.g., self-efficacy for pain control accounted for 32% of disease severity's total effect on pain). Variance accounted for by the total model was 52% for pain, 53% for physical functioning, and 44% for affective and social functioning.

CONCLUSION

Disease severity and self-efficacy both impact RA functioning, and intervening in these areas may lead to better outcomes.

Self-management for osteoarthritis of the knee: does mode of delivery influence outcome?

BACKGROUND

Self-management has become increasingly popular in the management of chronic diseases. There are many different self-management models. Meta analyses of arthritis self-management have concluded that it is difficult to recommend any one program in preference to another due to inconsistencies in the study designs used to evaluate different programs.The Stanford Arthritis Self-Management Program (ASMP), most commonly delivered by trained lay leaders, is a generic program widely used for people with rheumatological disorders. We have developed a more specific program expressly for people with osteoarthritis of the knee (OAKP). It includes information designed to be delivered by health professionals and results in improvements in pain, function and quality of life.

AIM

To determine whether, for people with osteoarthritis (OA) of the knee, the OAKP implemented in a primary health care setting can achieve and maintain clinically meaningful improvements in more participants than ASMP delivered in the same environment.

METHODS/DESIGN

The effectiveness of the programs will be compared in a single-blind randomized study.

PARTICIPANTS

146 participants with established OA knee will be recruited. Volunteers with coexistent inflammatory joint disease or serious co-morbidities will be excluded.

INTERVENTIONS

Participants will be randomised into either OAKP or ASMP groups and followed for 6 months.

MEASUREMENTS

Assessments will be immediately before and after the intervention and at 6 months. Primary outcome measures will be WOMAC and SF-36 questionnaires and a VAS for pain. Secondary outcomes will include balance, tested using a timed single leg balance test and a timed step test and self-efficacy. Data will be analysed using repeated measures ANOVA.

DISCUSSION

With an aging population the health care costs for people with arthritis are ever increasing. Although cost analysis is beyond the scope of this study, it is reasonable to expect that costs will be greater when health professionals deliver self-management programs as opposed to lay leaders. Consequently it is critical to examine the relative effectiveness of the primary care management strategies available for OA.

TRIAL REGISTRATION

This study is registered with the Australian New Zealand Clinical Trials Registry: 12607000031460.

Predictors of disability and pain six months after the end of treatment for fibromyalgia

OBJECTIVES

The goal of this study was to identify factors associated with decreased disability and lower pain scores 6 months after a multimodal treatment program for fibromyalgia (FM).

METHODS

Forty-six patients with FM were assessed after having participated in a 3-month outpatient program integrating physiotherapy, occupational therapy, nursing, and cognitive-behavior therapy. A physician examined the patients before treatment and patients who completed a battery of psychosocial questionnaires at baseline, during treatment, at the end of treatment, and 3 and 6 months after the end of treatment. Two separate multivariable linear regression models were built to identify predictors of improvements in disability and pain.

RESULTS

Two predictors for improvement in disability were found: an increase in self-efficacy for pain during treatment and better general adherence during treatment. Similarly, one predictor for improvement in pain intensity was found: an increase in self-efficacy for pain during treatment.

DISCUSSION

Self-efficacy and adherence are 2 modifiable factors that influence disability and pain intensity in FM. These psychosocial factors need to be addressed in FM treatment programs to assist patients in maintaining posttreatment improvements.

Disease Severity in Ankylosing Spondylitis: Variation by Region and Local Area Deprivation

Objective.

To investigate whether patient disease severity in ankylosing spondylitis (AS) varies among regions or by local area social deprivation.

Methods.

Eight hundred patients with AS from 8 specialist rheumatology centers across England were invited to participate in a cross-sectional survey. Sociodemographic and disease-related variables were collected [pain (numerical rating scale), disease activity (Bath AS Disease Activity Index), and physical function (Bath AS Functional Index)]. Deprivation was measured using the Index of Multiple Deprivation 2004.

Results.

Of the 800 patients invited, 468 responded (adjusted response rate 62.8%). Most were male (72.9%), with a mean age of 50.2 years (SD 12.1), and a mean diagnosed disease duration of 17 years (SD 11.4). Across all centers, those living in more deprived areas demonstrated significantly greater disease severity and poorer psychological health. After controlling for age, gender, disease duration, and region, greater deprivation was significantly associated with greater disease activity (OR 3.39; 95% CI 1.65, 6.98) and poorer function (OR 4.46; 95% CI 2.11, 9.44). There was a nonsignificant trend toward more pain (OR 1.98; 95% CI 0.97, 4.07). There was also a significant independent association between region and disease severity.

Conclusion.

The need for healthcare is greatest for patients with AS who are living in more socially deprived areas. With the growing use of interventional therapies, these findings have important implications if health service resources are to be allocated equitably; particularly as deprived patients are known to access healthcare less frequently.

Sleep disruption frequency in rheumatoid arthritis: perceived stress predicts poor outcome over one year

BACKGROUND

Sleep is an important daily process that can be disrupted by chronic illnesses including rheumatoid arthritis (RA).

AIMS

We tested whether demographic, medical and psychological factors act as predictors of change in frequency of sleep disruption associated with RA.

METHODS

A cohort of 129 White British people with RA (mean duration of RA 7.19 years; mean age 55.40 years; 75% women) was followed for one year. Self-report questionnaires were employed to record demographic information and assess participants' sleep disruption (on a 4-point frequency scale), morning stiffness (duration), pain and fatigue (visual analogue scales), impact of disability, anxiety, depression, stress, coping, illness perceptions and self-efficacy. Hospital notes were reviewed for duration of RA, antidepressant use and comorbidity.

RESULTS

Participants were split into those with sleep disruption that was consistently infrequent or decreasing in frequency (n = 56; 43%) and those with sleep disruption that was consistently frequent or increasing in frequency (n = 73; 57%). Results of a logistic regression demonstrated that greater perceived stress at baseline predicted sleep disruption that was consistently frequent or increasing in frequency over the year. Change in sleep disruption frequency was not predicted by any other assessed variable. Perceived stress at the end of the year was not predicted by change in frequency of sleep disruption.

CONCLUSIONS

Self-reported frequency of sleep disruption among people with RA relates to perceived stress. Psychoeducational programmes that help people with RA manage their stress may be a non-pharmacological method of improving sleep quality and therefore merits testing in specific interventional studies.

Impact of an Arthritis Self-Management Programme with an added exercise component for osteoarthritic knee sufferers on improving pain, functional outcomes, and use of health care services: An experimental study

OBJECTIVE

The aim of this study was to assess the effect of an adopted Arthritis Self-Management Programme (ASMP) with an added exercise component among osteoarthritic knee sufferers in Hong Kong.

METHODS

An experimental study with 88 participants assigned to an intervention group and 94 participants to a control group. One hundred and forty-nine participants (81.9%) completed the 1 week and 120 participants (65.6%) the 16 week post-intervention assessments. Participants in the intervention group received a 6-week ASMP with an added exercise component. Outcome measures included arthritic pain and fatigue rating, practice of light exercise routines, functional status, and number of unplanned arthritis-related medical consultations. To assess the programme's effect on outcome measures, the between-groups and within-group mean changes were compared using Mann-Whitney U-test and Friedman test.

RESULTS

At 16 weeks, there were significant mean changes between groups in four outcome measures: reduction in arthritis pain (p=0.0001) and fatigue (p=0.008), and increased duration of weekly light exercise practice (p=0.0001) and knee flexion (p=0.004). The ability to perform daily activities and the number of unplanned arthritis-related medical consultations show statistically significant improvements between three time-points within the intervention group only (p=0.0001 and p=0.005, respectively), but not between-groups (p=0.14 and p=0.86, respectively). Both groups apparently had no changes in muscle strength.

CONCLUSION

Our findings suggest that the intervention had a positive effect in reducing pain, fatigue, knee range of motion, the practice of exercise routines, the number of medical consultations and in improving functional status and over a 16-week period.

PRACTICE IMPLICATIONS

The self-management programme we applied took into account the local context and the ethnicity of the group. This process is worth further exploration and testing in different groups.

Requesting organ donation: the case of self-efficacy--effects of the European Donor Hospital Education Programme (EDHEP)

One of the major reasons for the shortage of donor organs is the high number of refusals by relatives. Studies have shown that the quality of communication with bereaved relatives influences whether to object or agree to organ and/or tissue donation. Breaking news of brain stem death, approaching relatives for permission to donate organs while also appropriately managing emotional reactions of relatives are complex tasks, which require knowledge of the domains as well as adequate skills to communicate information and understanding. In this study the effect of the European Donor Hospital Education Programme (EDHEP) on the self-efficacy of Intensive Care staff is evaluated. Self-efficacy scores significantly improved after attending EDHEP; an effect that was maintained at six month follow-up. EDHEP participants with high baseline scores on self-efficacy, maintained the increase at follow-up. EDHEP participants with low baseline scores on self-efficacy showed the greatest increase at the post-test. Increases in self-efficacy were significantly related to decreases in the perceived difficulty of requesting. Experience had a significant effect on both self-efficacy beliefs and perceived difficulty of requesting donation. As self-efficacy beliefs are perceived as better predictors for future behaviour than prior attainments, the results call for further research in this domain. The data indicate that training programmes should be tailored not only to working circumstances of participants, but should also take levels of experience and self-efficacy into account. Further study is necessary and the best way to proceed is to relate the outcomes of this study to behavioural outcomes.

Educational preferences, psychological well-being and self-efficacy among people with rheumatoid arthritis

As a basis for developing interventions to meet the psycho-educational needs of rheumatoid arthritis (RA) outpatients attending a regional hospital have been investigated. Specifically, patients' preferences for interventions addressing education (e.g. the disease and its treatment), self-management (e.g. pain-management, exercise) and the consequences (e.g. emotions, impact on work, family relationships) of RA were examined. In addition, psychological well-being and self-efficacy were examined. Results showed that patients preferred education about the disease and its treatment to be delivered on a one-to-one basis by health professionals. Similarly, emotional issues were believed to be best dealt with one-to-one although this could be with a similar other (i.e. a patient). Group interventions were the preferred format for self-management, exercise and relationship issues, whereas videos were thought to be useful for demonstrating use of aids and how other families cope. None of the participants would welcome computer-based interventions. Psychological well-being (e.g. depression, anxiety) remained stable over a 12-month period. Both physical and psychological health status were correlated with arthritis self-efficacy. The implications of these findings are discussed in relation to development of interventions to better meet the psycho-educational needs of outpatients with RA.

Patient education for people with arthritis in rural communities: the UK experience

Research literature, based largely on studies conducted in the USA and Australia, suggests that rural and urban residents differ on health status variables. This assumption was examined in an exploratory study conducted in the UK. The experience of arthritis in rural communities was explored through interviews and comparisons were made between rural and urban participants attending an educational intervention designed to improve self-management ability. Results showed that rural residents valued their independence and the sense of community spirit. Contrary to expectations, urban rather than rural residents showed greater psychological distress. However, the effectiveness of the educational intervention was found to be independent of location; both urban and rural dwellers appeared to derive similar benefits.

Development and preliminary validation of a children's arthritis self-efficacy scale

OBJECTIVE

To develop a valid and reliable measure of arthritis self-efficacy for use with school-age children with juvenile idiopathic arthritis (JIA).

METHODS

Construction of the 11-item Children's Arthritis Self-Efficacy Scale (CASE) was based on an existing body of knowledge and the results of focus groups with children, their parents, and health professionals. Data for validation of the CASE were collected by self-administered questionnaires completed by 89 children and 151 caregivers.

RESULTS

Analyses revealed a 3-factor structure relating to self-efficacy for managing symptoms, emotional consequences, and activities, explaining 76.5% of the total variance. The CASE demonstrated high internal consistency, concurrent validity, and construct validity.

CONCLUSION

Preliminary findings suggest that the CASE is worthy of further psychometric testing and may have the potential to help delineate variations in adjustment among children with JIA.

A randomised controlled trial. Shifting boundaries of doctors and physiotherapists in orthopaedic outpatient departments

OBJECTIVE

To evaluate the effectiveness and cost effectiveness of specially trained physiotherapists in the assessment and management of defined referrals to hospital orthopaedic departments.

DESIGN

Randomised controlled trial.

SETTING

Orthopaedic outpatient departments in two hospitals.

SUBJECTS

481 patients with musculoskeletal problems referred for specialist orthopaedic opinion.

INTERVENTIONS

Initial assessment and management undertaken by post-Fellowship junior orthopaedic surgeons, or by specially trained physiotherapists working in an extended role (orthopaedic physiotherapy specialists).

MAIN OUTCOME MEASURES

Patient centred measures of pain, functional disability and perceived handicap.

RESULTS

A total of 654 patients were eligible to join the trial, 481 (73.6%) gave their consent to be randomised. The two arms (doctor n = 244, physiotherapist n = 237) were similar at baseline. Baseline and follow up questionnaires were completed by 383 patients (79.6%). The mean time to follow up was 5.6 months after randomisation, with similar distributions of intervals to follow up in both arms. The only outcome for which there was a statistically or clinically important difference between arms was in a measure of patient satisfaction, which favoured the physiotherapist arm. A cost minimisation analysis showed no significant differences in direct costs to the patient or NHS primary care costs. Direct hospital costs were lower (p < 0.00001) in the physiotherapist arm (mean cost per patient = 256 Pounds, n = 232), as they were less likely to order radiographs and to refer patients for orthopaedic surgery than were the junior doctors (mean cost per patient in arm = 498 Pounds, n = 238).

CONCLUSIONS

On the basis of the patient centred outcomes measured in this randomised trial, orthopaedic physiotherapy specialists are as effective as post-Fellowship junior staff and clinical assistant orthopaedic surgeons in the initial assessment and management of new referrals to outpatient orthopaedic departments, and generate lower initial direct hospital costs.
