A qualitative evaluation of occupational therapy-led work rehabilitation for people with inflammatory arthritis: Patients' views

Critical Realism in Symptom Science - A Scoping Review

There has been an increasing interest in research positioned within critical realism (CR). This analysis aimed to determine how CR has been applied in symptom science through a scoping review of the literature. Fifty-two articles were identified through searches in seven databases and search engines, and grey literature. Quantitative and qualitative analyses were performed using Excel and ATLAS.ti 8.0. Review findings indicate that CR has been used to examine two key aspects of symptoms - symptom experiences and symptom interventions. The details of how CR was operationalized are presented. This first scoping review highlights how a critical realist lens would help examine individual and contextual factors that influence symptom experiences, response to interventions, and outcomes.

Overview of Rheumatoid Arthritis and Scientific Understanding of the Disease

Rheumatoid arthritis (RA), a chronic inflammatory autoimmune disorder, is characterised by persistent synovial inflammation, erosion of bones and cartilage, leading to joint destruction. Clinical manifestations are morning stiffness, pain in shoulder, neck and pelvic girdle, loss of mobility with fever, fatigue, malaise, loss of body weight, and development of rheumatoid nodules. Environmental and genetic factors are important contributors in its susceptibility. Association between RA and diet, cigarette smoking, hormones, alcohol, microbiota, infection, and coffee have also been reported. To diagnose patients with RA, American college of rheumatology (ACR, 2010) criteria, developed by European league against rheumatism (EULAR). Inflammation produced in RA patients is due to cell-mediated immune response. The rheumatoid synovium consists of a large number of CD4+ T cells suggesting pathogenic nature of T cells in this disorder. B-cells may also participate in the pathogenesis by several means such as autoantibodies, by instigation of T-cells through expression of co-stimulatory molecules, by generating pro-inflammatory and anti-inflammatory cytokines and by organisation of other inflammatory cells. The conventional management of RA usually focuses over reducing pain and limiting the disability by medical therapies which include a number of classes of agents such as non-steroidal anti-inflammatory drugs (NSAIDs), non-biological and biological agents, disease-modifying anti rheumatic drugs (DMARDs), immunosuppressants, and corticosteroids. However, only proper rehabilitation can promote the objective to achieve the joint functionality and ease of motion which improves independence as well as quality of life in patient suffering from Rheumatoid Arthritis.

Developing a complex vocational rehabilitation intervention for patients with inflammatory arthritis: the WORK-ON study

BACKGROUND

People with inflammatory arthritis often experience challenges at work and balancing paid work and energy in everyday life. Low work ability is common, and people with inflammatory arthritis face high risks of losing their jobs and permanent exclusion from the labour market. Context-specific tailored rehabilitation targeting persons with inflammatory arthritis is limited. The aim of this study is to describe the development of WORK-ON - a vocational rehabilitation for people with inflammatory arthritis.

METHODS

Following the Medical Research Council's framework for complex interventions, WORK-ON was developed based on existing evidence, interviews with patients and rehabilitation clinicians, a workshop, and an iterative process.

RESULTS

The six-month vocational rehabilitation, WORK-ON, consists of 1) an initial assessment and goal setting by an occupational therapist experienced in rheumatology rehabilitation, 2) coordination by the same occupational therapist and individual support, including navigating across the primary and secondary health sectors, as well as social care, 3) group sessions for peer support, and 4) optionally individually tailored consultations with physiotherapists, nurses, or social workers.

CONCLUSION

WORK-ON is ready to be tested in a feasibility study.

TRIAL REGISTRATION

The Regional Committees on Health Ethics for Southern Denmark stated that no formal ethical approval was necessary in this study (20,192,000-105).

The Workwell trial: protocol for the process evaluation of a randomised controlled trial of job retention vocational rehabilitation for employed people with inflammatory arthritis

Background

The Workwell trial is a multi-centre randomised controlled trial with the aims of evaluating the effectiveness and cost-effectiveness of job retention vocational rehabilitation for employed people with inflammatory arthritis, who are experiencing work difficulties due to their arthritis. Vocational rehabilitation is delivered by health service occupational therapists, who have received additional training in providing this Workwell intervention. A process evaluation will be undertaken alongside the main trial to investigate implementation fidelity; understand key stakeholders’ perspectives of the intervention and the social and structural context in which the intervention is provided; and explore issues related to future implementation in clinical practice. This protocol describes the aims, objectives, and methodology of the Workwell trial process evaluation.

Methods

This mixed methods process evaluation will follow the Medical Research Council’s Guidance on process evaluations for complex interventions. It will be underpinned by the conceptual framework for implementation fidelity (CFIF) and normalisation process theory (NPT). We will analyse treatment records, work assessments, and treatment notes to ascertain implementation fidelity. Semi-structured interviews with trial participants, their employer/line managers, treating therapists, and their therapy service managers will be undertaken to explore perceptions of the intervention, contextual factors, and potential for future implementation in practice. Interview topic guides will be informed by NPT. Therapists’ views about Workwell training will be explored via questionnaires following training, and interviews and focus groups following treatment delivery to inform future implementation. Quantitative data will be analysed descriptively. Qualitative data will be analysed using thematic analysis. NPT will guide data analysis and interpretation. Findings from the different elements of this embedded design process evaluation will be reported separately and then the elements integrated. The process evaluation data will be analysed independently of the Workwell trial outcome evaluation. The process evaluation data will then be reviewed in the light of the trial findings.

Discussion

Few trials of job retention vocational rehabilitation in arthritis have included process evaluations. This process evaluation will assist in understanding factors influencing trial outcomes and identifying potential contextual barriers and facilitators for the potential implementation of Workwell vocational rehabilitation into clinical services.

Perceived challenges at work and need for professional support among people with inflammatory arthritis - a qualitative interview study

BACKGROUND

People with inflammatory arthritis (IA) often experience low work ability, and up to 38% lose their jobs during the initial years after the diagnosis of IA.

AIM

We explore the perceived challenges at work and identify the need for professional support among Danish people with IA.

MATERIALS/METHODS

Individual explorative interviews based on a hermeneutic approach. We used Graneheim and Lundman's qualitative content analysis.

RESULTS

Eleven women and four men with IA (aged 36-68 years) who worked full or part time, or were on short-term sick leave, participated. The analysis revealed one main theme, Balancing work as part of everyday life, and four sub-themes: 1) Working despite challenges, 2) Prioritising energy for work, 3) Fatigue leading to lack of control, and 4) Need for flexibility and recognition.

CONCLUSIONS

People with IA prioritise staying at work despite experiencing challenges with fatigue and balancing their work and energy in everyday life. They need recognition, support and flexibility at work to be able to continue in their jobs.

SIGNIFICANCE

The study highlights the need to be aware of occupational balance and, thus, to include other aspects in life apart from just work. It points at occupational therapists as relevant partners in vocational rehabilitation.

The effect on work presenteeism of job retention vocational rehabilitation compared to a written self-help work advice pack for employed people with inflammatory arthritis: protocol for a multi-centre randomised controlled trial (the WORKWELL trial)

Background

Work problems are common in people with inflammatory arthritis. Up to 50% stop work within 10 years due to their condition and up to 67% report presenteeism (i.e. reduced work productivity), even amongst those with low disease activity. Job retention vocational rehabilitation (JRVR) may help prevent or postpone job loss and reduce presenteeism through work assessment, work-related rehabilitation and enabling job accommodations. This aims to create a better match between the person’s abilities and their job demands. The objectives of the Workwell trial are to test the overall effectiveness and cost-effectiveness of JRVR (WORKWELL) provided by additionally trained National Health Service (NHS) occupational therapists compared to a control group who receive self-help information both in addition to usual care.

Methods

Based on the learning from a feasibility trial (the WORK-IA trial: ISRCTN76777720), the WORKWELL trial is a multi-centre, pragmatic, individually-randomised parallel group superiority trial, including economic evaluation, contextual factors analysis and process evaluation. Two hundred forty employed adults with rheumatoid arthritis, undifferentiated inflammatory arthritis or psoriatic arthritis (in secondary care), aged 18 years or older with work instability will be randomised to one of two groups: a self-help written work advice pack plus usual care (control intervention); or WORKWELL JRVR plus a self-help written work advice pack and usual care. WORKWELL will be delivered by occupational therapists provided with additional JRVR training from the research team. The primary outcome is presenteeism as measured using the Work Limitations Questionnaire-25. A comprehensive range of secondary outcomes of work, health, contextual factors and health resource use are included. Outcomes are measured at 6- and 12- months (with 12-months as the primary end-point). A multi-perspective within-trial cost-effectiveness analyses will also be conducted.

Discussion

This trial will contribute to the evidence base for provision of JRVR to people with inflammatory arthritis. If JRVR is found to be effective in enabling people to keep working, the findings will support decision-making about provision of JRVR by rheumatology teams, therapy services and healthcare commissioners, and providing evidence of the effectiveness of JRVR and the economic impact of its implementation.

Job retention vocational rehabilitation for employed people with inflammatory arthritis (WORK-IA): a feasibility randomized controlled trial

BACKGROUND

Inflammatory arthritis leads to work disability, absenteeism and presenteeism (i.e. at-work productivity loss) at high cost to individuals, employers and society. A trial of job retention vocational rehabilitation (VR) in the United States identified this helped people keep working. The effectiveness of this VR in countries with different socioeconomic policies and conditions, and its impact on absenteeism, presenteeism and health, are unknown. This feasibility study tested the acceptability of this VR, modified for the United Kingdom, compared to written advice about managing work problems. To help plan a randomized controlled trial, we tested screening, recruitment, intervention delivery, response rates, applicability of the control intervention and identified the relevant primary outcome.

METHODS

A feasibility randomized controlled trial with rheumatoid, psoriatic or inflammatory arthritis patients randomized to receive either job retention VR or written information only (the WORK-IA trial). Following three days VR training, rheumatology occupational therapists provided individualised VR on a one to one basis. VR included work assessment, activity diaries and action planning, and (as applicable) arthritis self-management in the workplace, ergonomics, fatigue and stress management, orthoses, employment rights and support services, assistive technology, work modifications, psychological and disclosure support, workplace visits and employer liaison.

RESULTS

Fifty five (10%) people were recruited from 539 screened. Follow-up response rates were acceptable at 80%. VR was delivered with fidelity. VR was more acceptable than written advice only (7.8 versus 6.7). VR took on average 4 h at a cost of £135 per person. Outcome assessment indicated VR was better than written advice in reducing presenteeism (Work Limitations Questionnaire (WLQ) change score mean: VR = -12.4 (SD 13.2); control = -2.5 (SD 15.9), absenteeism, perceived risk of job loss and improving pain and health status, indicating proof of concept. The preferred primary outcome measure was the WLQ, a presenteeism measure.

CONCLUSIONS

This brief job retention VR is a credible and acceptable intervention for people with inflammatory arthritis with concerns about continuing to work due to arthritis.
