Non-pharmacological interventions for preventing job loss in workers with inflammatory arthritis

Characteristics of refractory disease and persistent symptoms in inflammatory arthritis: Qualitative framework analysis of interviews with patients and health care professionals

OBJECTIVES

This study aims to explore patients' and clinicians' understanding and experiences of refractory disease (RD) and persistent physical and emotional symptoms (PPES) in patients with inflammatory arthritis (IA), namely rheumatoid arthritis or polyarticular juvenile idiopathic arthritis from their perspectives through interviews and/or focus groups.

DESIGN

A qualitative study was conducted, following a pragmatic epistemology approach with framework analysis employed.

METHODS

Semi-structured interviews or focus groups with IA patients (n = 25) and multi-disciplinary rheumatology HCPs (n = 32) were conducted at one time point to obtain participants respective understanding and experiences of managing RD/PPES, and its impact on the patient-professional relationship.

RESULTS

Three key themes were identified from both patients and professionals' experiences of RD/PPES: (1) relevant treatment experiences, (2) symptoms (with or without inflammation) and (3) impact: physical, psychological and social. These themes included 28 specific categories that would be considered as components characterizing RD/PPES, most common to both patients and HCPs with six being patient-specific and only one HCP-specific. The specific biopsychosocial symptoms and impacts of RD/PPES pertain to pain, fatigue, stiffness, joint involvement and physical, psychological and social functioning and quality of life, covering disease-related distress, mobility and independence. Wider influential factors such as comorbidities, non-adherence, health/medication beliefs and behaviours and social support were also identified.

CONCLUSION

Common persistent symptoms that have both mental and physical impact characterize RD/PPES in IA and therefore a more integrated holistic approach to treatment is needed from multi-disciplinary HCPs, including health psychologists.

Occupational impacts of early inflammatory arthritis: results from the National Early Inflammatory Arthritis Audit

OBJECTIVES

Inflammatory arthritis causes significant work disability. Studies regarding this frequently fail to report important contextual information such as employment type. Our objective was to explore work participation, by gender and occupation type, in early inflammatory arthritis.

METHODS

Data are from the National Early Inflammatory Arthritis Audit for 2018-2020. At diagnosis, clinicians collected information on demographics, inflammatory arthritis disease activity, and working status. Participants completed patient-reported outcomes at baseline, 3 months and 12 months, including occupation and Work Productivity and Activity Impairment (WPAI). Descriptive analyses of work participation and WPAI scores by occupational class at all time points were performed. Regression models were used to examine associations between WPAI score and occupation.

RESULTS

In all, 12 473 people received a diagnosis of inflammatory arthritis and reported employment status, among whom 5999 (47%) were in paid work for at least 20 hours/week. At diagnosis, the working cohort had statistically significant lower measures of disease activity (P < 0.001). Occupational data were available for 3694 individuals. At diagnosis, 2793 completed a WPAI; 200 (7.2%) had stopped work and 344 (12.3%) changed jobs because of inflammatory arthritis symptoms. There was a high burden of absenteeism (30%) and presenteeism (40%). Compared with managerial or professional workers, the burden of work disability was greater among those in routine (manual) occupations. During follow-up, 9.4% of WPAI completers stopped work and 14.6% changed roles. Work drop-out occurred almost entirely among people doing routine jobs.

CONCLUSION

It is easier to retain work in certain employment sectors. Participation in routine jobs is more affected, which may widen health inequalities.

What is the volume, quality and characteristics of evidence relating to the effectiveness and cost-effectiveness of multi-disciplinary occupational health interventions aiming to improve work-related outcomes for employed adults? An evidence and gap map of systematic reviews

Background

In the UK, tens of millions of working days are lost due to work-related ill health every year, costing billions of pounds. The role of Occupational Health (OH) services is vital in helping workers to maintain employment when they encounter injury or illness. OH providers traditionally rely on a clinical workforce to deliver these services, particularly doctors and nurses with OH qualifications. However, the increasing demand for OH services is unlikely to be met in the future using this traditional model, due to the declining number of OH-trained doctors and nurses in the UK. Multi-disciplinary models of OH delivery, including a more varied range of healthcare and non-healthcare professionals, could provide a way to meet this new demand for OH services. There is a need to identify collaborative models of OH service delivery and review their effectiveness on return-to work outcomes. There is an existing pool of systematic review evidence evaluating workplace based, multi-disciplinary OH interventions, but it is difficult to identify which aspects of the content and/or delivery of these interventions may be associated with improved work-related outcomes.

Objectives

The aim of this evidence and gap map (EGM) was to provide an overview of the systematic review evidence that evaluates the effectiveness and cost-effectiveness of multi-disciplinary OH interventions intending to improve work-related outcomes.

Search Methods

In June 2021 we searched a selection of bibliographic databases and other academic literature resources covering a range of relevant disciplines, including health care and business studies, to identify systematic review evidence from a variety of sectors of employment. We also searched Google Search and a selection of topically relevant websites and consulted with stakeholders to identify reports already known to them. Searches were updated in February 2023.

Selection Criteria

Systematic reviews needed to be about adults (16 years or over) in employment, who have had absence from work for any medical reason. Interventions needed to be multi-disciplinary (including professionals from different backgrounds in clinical and non-clinical professions) and designed to support employees and employers to manage health conditions in the workplace and/or to help employees with health conditions retain and/or return to work following medical absence. Effectiveness needed to be measured in terms of return to work, work retention or measures of absence, or economic evaluation outcomes. These criteria were applied to the title and abstract and full text of each systematic review independently by two reviewers, with disagreements resolved through discussion. We awarded each systematic review a rating of 'High', 'Medium' or 'Low' relevance to indicate the extent to which the populations, interventions and their contexts synthesised within the review were consistent with our research question. We also recorded the number of primary studies included within each of the 'High' and 'Medium' reviews that were relevant to research question using the same screening process applied at review level.

Data Collection and Analysis

Summary data for each eligible review was extracted. The quality of the systematic reviews, rated as 'High' or 'Medium' relevance following full text screening, was appraised using the AMSTAR-2 quality appraisal tool. All data were extracted by one reviewer and checked by a second, with disagreements being settled through discussion. Summary data for all eligible systematic reviews were tabulated and described narratively. The data extracted from reviews of 'High' and 'Medium' relevance was imported into EPPI-Mapper software to create an EGM.

Stakeholder Involvement

We worked alongside commissioners and policy makers from the Department of Health and Social Care (DHSC) and Department of Work and Pensions (DWP), OH personnel, and people with lived experience of accessing OH services themselves and/or supporting employees to access OH services. Individuals contributed to decision making at all stages of the project. This ensured our EGM reflects the needs of individuals who will use it.

Main Results

We identified 98 systematic reviews that contained relevant interventions, which involved a variety of professionals and workplaces, and which measured effectiveness in terms of return to work (RTW). Of these, we focused on the 30 reviews where the population and intervention characteristics within the systematic reviews were considered to be of high or medium relevance to our research questions. The 30 reviews were of varying quality, split evenly between High/Moderate quality and Low/Critically-Low quality ratings. We did not identify any relevant systematic review evidence on any other work-related outcome of interest. Interventions were heterogenous, both within and across included systematic reviews. The EGM is structured according to the health condition experienced by participants, and the effectiveness of the interventions being evaluated, as reported within the included systematic reviews. It is possible to view (i) the quality and quantity of systematic review evidence for a given health condition, (ii) how review authors assessed the effectiveness or cost-effectiveness of the interventions evaluated. The EGM also details the primary studies relevant to our research aim included within each review.

Authors’ Conclusions

This EGM map highlights the array of systematic review evidence that exists in relation to the effectiveness or cost-effectiveness of multi-disciplinary, workplace-based OH interventions in supporting RTW. This evidence will allow policy makers and commissioners of services to determine which OH interventions may be most useful for supporting different population groups in different contexts. OH professionals may find the content of the EGM useful in identifying systematic review evidence to support their practice. The EGM also identifies where systematic review evidence in this area is lacking, or where existing evidence is of poor quality. These may represent areas where it may be particularly useful to conduct further systematic reviews.

Optimizing the Maastricht Work-Related Support intervention in clinical patient care: the value of integrating action research into intervention mapping

BACKGROUND

Healthcare professionals (HCPs) are increasingly recommended to play an important role in supporting people with chronic disease in work participation. An intervention for HCPs to provide work-related support to their patients in clinical care was developed with intervention mapping (Maastricht Work-Related Support; Maastricht WRS). Action research proposes 'combining research and practice', which allows us to incorporate experiences of HCPs while implementing and to realize intervention's full potential. Therefore, the aim of this study is to explore, by integrating action research into an intervention mapping approach, how experiences of HCPs with early implementation can be used to optimize the Maastricht WRS in clinical care.

METHODS

Semi-structured interviews were held with nine HCPs (response rate 82%), involved in care for people with inflammatory arthritis, knee problems or inflammatory bowel disease. Some of them were not yet trained in the Maastricht WRS while others had received the training and were providing the Maastricht WRS.

RESULTS

All participants regarded WRS an important part of clinical care. Untrained HCPs indicated a lack of knowledge and skills in providing the Maastricht WRS, and a need for tools. Trained HCPs were satisfied with the training and tools, but stressed that practical limitations hindered providing the Maastricht WRS. Action research showed that the intervention meets the needs of HCPs, but need some optimizations: (1) organizing 'intervision' for HCPs, (2) inform and activate patients to discuss work with their HCP, (3) update initial tools and (4) including patients' work status in the electronic patient system.

CONCLUSIONS

Action research integrated into intervention mapping proved to improve the Maastricht WRS intervention. By involving HCPs, the intervention could be optimized to provide to support people with chronic diseases in clinical care in healthy and sustainable work participation.

Testing the effectiveness of a Fatigue and Activity Management Education for Work (FAME-W) intervention for individuals with inflammatory arthritis: Study protocol for a randomized control trial

BACKGROUND

A work-focused fatigue management intervention, Fatigue and Activity Management Education for Work (FAME-W) programme was developed for individuals with inflammatory arthritis (IA) to manage fatigue in order to maintain demands of their work activities and tasks. This paper presents the protocol for a randomized control trial that will test the effectiveness and acceptability of FAME-W in improving work performance.

METHODS

This protocol presents a multisite randomized control trial and mixed methods process evaluation. Eligible participants will be aged 18-65 years with a diagnosis of inflammatory arthritis and will be in paid employment. The primary outcome of the study will be Work Role Functioning (WRF) questionnaire, and the secondary outcomes will be fatigue, mood, health-related quality of life (HRQOL) and pain. Data will be collected immediately pre- and post-intervention and at 3 months of follow-up. The process evaluation will consist of focus groups and individual interviews to explore participants' experiences of FAME-W. Occupational therapists delivering the programme will complete a facilitator log to assess the fidelity and quality of intervention implementations. Facilitators will participate in individual interviews to explore intervention delivery and acceptability.

RESULTS

Results will be expected to show that FAME-W will improve work performance by helping participants gain self-management strategies around managing fatigue and other symptoms related to fatigue.

CONCLUSION

It is hoped that FAME-W will be an effective and acceptable intervention for individuals with IA in improving work performance by helping them manage their symptoms.

The role of occupational therapy in providing vocational rehabilitation for inflammatory arthritis: A scoping review protocol

INTRODUCTION

Inflammatory arthritis (IA) significantly impacts people's ability to continue in work roles, despite advances in medical management. Employment is acknowledged as important for health and wellbeing. Facilitating work participation and employment reduces social welfare dependence for income, minimising societal cost. Internationally, pathways and processes are developing to maintain people with acquired conditions in the workplace. Occupational Therapy supports this process, with its biopsychosocial approach, giving a framework to consider the complex dynamic of a person's vocational rehabilitation (VR) needs. A scoping review framework was chosen to explore the diverse VR process and emerging focus on Occupational Therapy's role in providing VR for the IA population.

METHODS

The methodological framework for scoping reviews will be used to guide the process and structure of the scoping review. A search strategy will be implemented in all the major peer reviewed databases along with grey literature repositories for English language studies. Study selection will use the PRISMA-ScR flow chart against an agreed eligibility criteria by two independent reviewers. Data extraction from the final selection will be mapped out using tables and a supporting descriptive review reflecting on the original scoping review aim and objectives completed.

DISSEMINATION

Findings will be disseminated at all levels and in various formats to bring them to the attention of clinicians, researchers and policy makers as VR pathways are established and prioritised for the early IA population.

Which outcomes should always be measured in intervention studies for improving work participation for people with a health problem? An international multistakeholder Delphi study to develop a core outcome set for Work participation (COS for Work)

OBJECTIVE

Synthesising evidence of the effects of interventions to improve work participation among people with health problems is currently difficult due to heterogeneity in outcome measurements. A core outcome set for work participation is needed.

STUDY DESIGN AND SETTING

Following the Core Outcome Measures in Effectiveness Trials methodology, we used a five-step approach to reach international multistakeholder consensus on a core outcome set for work participation. Five subgroups of stakeholders took part in two rounds of discussions and completed two Delphi voting rounds on 26 outcomes. A consensus of ≥80% determined core outcomes and 50%-80% consensus was required for candidate outcomes.

RESULTS

Fifty-eight stakeholders took part in the Delphi rounds. Core outcomes were: 'any type of employment including self-employment', 'proportion of workers that return to work after being absent because of illness' and 'time to return to work'. Ten candidate outcomes were proposed, among others: 'sustainable employment', 'work productivity' and 'workers' perception of return to work'.

CONCLUSION

As a minimum, all studies evaluating the impact of interventions on work participation should include one employment outcome and two return to work outcomes if workers are on sick leave prior to the intervention.

Work-related support in clinical care for patients with a chronic disease: development of an intervention

BACKGROUND

Patients with a chronic disease are more vulnerable in the labor market, and work-related support in clinical care would enhance the timely support greatly needed in each phase of their working life. This paper describes the development of a generic stay-at-work intervention to provide work-related support in clinical care to patients with a chronic disease.

METHODS

Steps 1-4 of Intervention Mapping (IM) were combined with action research principles. A needs assessment (Step 1) involved the project group formation, a literature review, qualitative studies with healthcare professionals (HCPs; n = 9) and patients (n = 10), consultation with financial staff and testing, and resulted in objectives (Step 2). Guided by methods and applications (Step 3), the intervention was developed, tested and finalized (Step 4).

RESULTS

The needs assessment revealed the importance of behavioral change in HCPs, including changing attitude, self-efficacy, and social influence. For that purpose, a pathway and training sessions were developed. Testing these unveiled the need for practical tools and intervision. The final intervention comprises a care pathway as part of working routines, including screening, risk stratification, and tailored support. Practical tools, training sessions, and intervision for HCPs were developed.

CONCLUSIONS

Combining IM with action research principles resulted in a generic stay-at-work intervention in clinical care via behavioral change in HCPs. A generic care pathway, practical tools, training sessions, and intervision were developed. More specific alignment to specific patient groups is possible. To implement the intervention in another hospital, the local context, (financial) resources, and the national legislation should be considered.

A general framework for selecting work participation outcomes in intervention studies among persons with health problems: a concept paper

Background

Work participation is important for health and can be considered as engagement in a major area of life which is of significance for most people, but it can also be thought of as fulfilling or discharging a role. Currently, academic research lacks a comprehensive classification of work participation outcomes. The International Classification of Functioning is the foremost model in defining work functioning and its counterpart work disability, but it does not provide a critical (core) set of outcomes. Standardizing the definitions and nomenclature used in the research of work participation would ensure that the outcomes of studies are comparable, and practitioners and guideline developers can better decide what works best. As work participation is a broad umbrella term including outcome categories which need unambiguous differentiation, a framework needs to be developed first.

Aim

To propose a framework which can be used to develop a generic core outcome set for work participation.

Methods

First, we performed a systematic literature search on the concept of (work) participation, views on how to measure it, and on existing classifications for outcome measurements. Next, we derived criteria for the framework and proposed a framework based on the criteria. Last, we applied the framework to six case studies as a proof of concept.

Results

Our literature search provided 2106 hits and we selected 59 studies for full-text analysis. Based on the literature and the developed criteria we propose four overarching outcome categories: (1) initiating employment, (2) having employment, (3) increasing or maintaining productivity at work, and (4) return to employment. These categories appeared feasible in our proof-of-concept assessment with six different case studies.

Conclusion

We propose to use the framework for work participation outcomes to develop a core outcome set for intervention studies to improve work participation.

A Systematic Review of Job Loss Prevention Interventions for Persons with Inflammatory Arthritis

Purpose To present an overview of the evidence of the effect of job loss prevention interventions, aiming to improve work ability and decrease absenteeism and/or job loss in persons with inflammatory arthritis (IA). Method A systematic literature search in the databases PubMed, EMBASE, CINAHL, PsycINFO and the Cochrane Library was conducted. A search strategy used in a review from 2014 was copied and additional keywords were added with no time restriction. The Cochrane Risk of Bias Tool (RoB 1) was used for quality assessment and the overall quality of each study was determined using predetermined cut-off criteria, categorising studies to be of good-, acceptable- or low quality. Results were summarised narratively. Results Six randomised controlled trials (published in seven articles) were included, one of good quality and five of acceptable quality. One study identified significant improvements in work ability, while three found no significant difference between groups. One study identified significant difference in absenteeism, while two studies identified no difference between the intervention and control groups. Two studies identified significant reduction in job loss, while two studies identified no group difference. The inconsistent results may be due to heterogeneity in interventions and outcome measures used, and the results should therefore be interpreted with caution. Conclusion The results indicate that job loss prevention interventions may have an effect on work ability, absenteeism and in particular job loss among persons with IA. Further good-quality studies regarding job loss prevention interventions for people with IA are still recommended.

Predictors of presenteeism, absenteeism and job loss in patients commencing methotrexate or biologic therapy for rheumatoid arthritis

Objectives

Work is an important health outcome. This study aimed to identify predictors of work loss, absenteeism and presenteeism over 1 year in RA patients commencing treatment with MTX or biologics.

Methods

Patients aged 18–65 years in full/part-time employment from two UK prospective cohorts were included: MTX-starters = Rheumatoid Arthritis Medication Study; and biologic-starters = Biologics in Rheumatoid Arthritis Genetics and Genomics Study Syndicate. Presenteeism and absenteeism were assessed using the RA-specific Work Productivity Survey at baseline, and 6 and 12 months. Potential predictors including baseline age, gender, clinical measures (e.g. disability, pain, fatigue), psychological distress, occupation and EULAR response from baseline to 6 months were investigated.

Results

A total of 51/463 MTX-starters and 30/260 biologic-starters left work over 12 months. Higher baseline psychological distress in MTX-starters [odds ratio (OR) 1.1 (95% CI: 1.0, 1.1)] and higher disability in biologic-starters [OR 3.5 (95% CI: 1.4, 8.6)] predicted work loss. Some 16.1% of patients reported sick-leave, which was predicted by disability [OR (95% CI): MTX-starters: 1.5 (0.9, 2.3); biologic-starters: 2.4 (1.1, 5.2)]. Median presenteeism scores were very low (minimal interference) in both cohorts. Higher fatigue for MTX starters [incidence rate ratio 1.2 (95% CI: 1.0, 1.4)] and higher disability in biologic-starters (incidence rate ratio 1.4 (95% CI: 1.1, 1.7)] predicted presenteeism. Good EULAR response was associated with lower absenteeism and presenteeism in both cohorts.

Conclusion

Patients with RA still face significant limitations regarding their ability to work. Disability and EULAR response were the main predictors of work outcomes, emphasizing the need to control the disease and the importance of function in enabling work participation.

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.

Assessing the effect of interventions for axial spondyloarthritis according to the endorsed ASAS/OMERACT core outcome set: a meta-research study of trials included in Cochrane reviews

The Assessment of SpondyloArthritis international Society (ASAS) has defined core sets for (i) symptom-modifying anti-rheumatic drugs (SM-ARD), (ii) clinical record keeping, and (iii) disease-controlling anti-rheumatic therapy (DC-ART). These include the following domains for all three core sets: “physical function,” “pain,” “spinal mobility,” “spinal stiffness,” and “patient’s global assessment” (PGA). The core set for clinical record keeping further includes the domains “peripheral joints/entheses” and “acute phase reactants,” and the core set for DC-ART further includes the domains “fatigue” and “spine radiographs/hip radiographs.” The Outcome Measures in Rheumatology (OMERACT) endorsed the core sets in 1998.

Using empirical evidence from axSpA trials, we investigated the efficacy (i.e., net benefit) according to the ASAS/OMERACT core outcome set for axSpA across all interventions tested in trials included in subsequent Cochrane reviews. For all continuous scales, we combined data using the standardized mean difference (SMD) to meta-analyze outcomes involving the same domains. Also, through meta-regression analysis, we examined the effect of the separate SMD measures (independent variables) on the primary endpoint (log [OR], dependent variable) across all trials.

Based on 11 eligible Cochrane reviews, from these, 85 articles were screened; we included 43 trials with 63 randomized comparisons. Mean (SD) number of ASAS/OMERACT core outcome domains measured for SM-ARD/physical therapy trials was 4.2 (1.7). Six trials assessed all proposed domains. Mean (SD) for number of core outcome domains for DC-ART trials was 5.8 (1.7). No trials assessed all nine domains. Eight trials (16%) were judged to have inadequate (i.e., high risk of) selective outcome reporting bias. The most responsible core domains for achieving success in meeting the primary objective per trial were pain, OR (95% CI) 5.19 (2.28, 11.77), and PGA, OR (95% CI) 1.87 (1.14, 3.07). In conclusion, selective outcome reporting (and “missing data”) should be reduced by encouraging the use of the endorsed ASAS/OMERACT outcome domains in clinical trials. Overall outcome reporting was good for SM-ARD/physical therapy trials and poor for DC-ART trials. Our findings suggest that both PGA and pain provide a valuable holistic construct for the assessment of improvement beyond more objective measures of spinal inflammation.

Workplace-based interventions to promote healthy lifestyles in the NHS workforce: a rapid scoping and evidence map

Background

The health and well-being of staff working in the NHS is a significant issue for UK health care. We sought to identify research relevant to the promotion of healthy lifestyles among NHS staff on behalf of NHS England.

Objectives

To map existing reviews on workplace-based interventions to promote health and well-being, and to assess the scope for further evidence synthesis work.

Design

Rapid and responsive scoping search and evidence map.

Participants

Adult employees in any occupational setting and in any role.

Interventions

Any intervention aimed at promoting or maintaining physical or mental health and well-being. Early intervention initiatives and those addressing violence against staff, workplace bullying or harassment were also included.

Main outcome measures

Any outcome related to the effectiveness, cost-effectiveness or implementation of interventions.

Data sources

A scoping search of nine databases was conducted to identify systematic reviews on health and well-being at work. Searches were limited by publication date (2000 to January/February 2019).

Review methods

The titles and abstracts of over 8241 records were screened and a total of 408 potentially relevant publications were identified. Information on key characteristics were extracted from the titles and abstracts of all potentially relevant publications. Descriptive statistics (counts and percentages) for key characteristics were generated and data from reviews and ‘reviews of reviews’ were used to produce the evidence map.

Results

Evidence related to a broad range of physical and mental health issues was identified across 12 ‘reviews of reviews’ and 312 other reviews, including 16 Cochrane reviews. There also exists National Institute for Health and Care Excellence guidance addressing multiple issues of potential relevance. A large number of reviews focused on mental health, changing lifestyle behaviour, such as physical activity, or on general workplace health/health promotion. Most of the reviews that focused only on health-care staff addressed mental health issues, and stress/burnout in particular.

Limitations

The scoping search process was extensive and clearly effective at identifying relevant publications, but the strategy used may not have identified every potentially relevant review. Owing to the large number of potentially relevant reviews identified from the scoping search, it was necessary to produce the evidence map using information from the titles and abstracts of reviews only.

Conclusions

It is doubtful that further evidence synthesis work at this stage would generate substantial new knowledge, particularly within the context of the NHS Health and Wellbeing Framework[NHS England. Workforce Health and Wellbeing Framework. 2018. URL: www.nhsemployers.org/-/media/Employers/Publications/Health-and-wellbeing/NHS-Workforce-HWB-Framework_updated-July-18.pdf (accessed 10 January 2019)] published in 2018. Additional synthesis work may be useful if it addressed an identifiable need and it was possible to identify one of the following: (1) a specific and focused research question arising from the current evidence map; it may then be appropriate to focus on a smaller number of reviews only, and provide a more thorough and critical assessment of the available evidence; and (2) a specific gap in the literature (i.e. an issue not already addressed by existing reviews or guidance); it may then be possible to undertake further literature searching and conduct a new evidence review.

Links between organizational preparedness and employee action to seek support among a Japanese working population with chronic diseases

Objectives

This study examined the association between workplace rules and training programs regarding combining employees’ work and treatment for chronic diseases, and actions actually taken by employees to manage this issue. These workplace measures (rules and training programs) are consistent with the Japanese Guideline for Workplace Patient Coordination and Disease Treatment.

Methods

In February 2018, we conducted an online, cross‐sectional survey of 1134 employed individuals with chronic diseases who needed workplace support to combine work and disease treatment. All participants were aged 18‐65 years and lived in Japan. We investigated associations between workplace rules and training programs (two items) and employee actions (eight items), using a questionnaire based on the guideline and logistic regression analysis.

Results

In total, 76.5% of the participants said they had reported their chronic disease to their employer (manager, personnel department, or occupational physician). However, less than half (47.5%) had submitted a written report about their job to their doctor. Employees were more likely to take action in workplaces that had rules or training programs than in workplaces without such measures. More actions were taken among employees in workplaces with both rules and training programs than in those with either measure alone.

Conclusion

It is important to establish rules to support employees with chronic diseases and provide training to improve awareness of these rules to encourage employees with chronic diseases to take action to access the support they need.

The Role of Adipose Derived Mesenchymal Stem Cells (MSCs) to Control Autoimmune Disease

There are 80 types of autoimmune diseases (ADs) with some of the same symptoms, but causes are still unclear. The major treatment of ADs is immunosuppressive drugs but these are not effective and associated with substantial toxicities. Stem cell has demonstrated remarkable effectiveness in halting destructive immune response and restoring the body to level of normal function by providing cellular level repair of damage, increasing blood flow, and reducing inflammation. Adipose tissue is one of the most potent and concentrated source of mesenchymal stem cells (MSCs) as an anti-inflammatory and tissue protecting agent which is promote healing and minimal invasive. This study conducted in 20 patients with ADs (11 women and 9 men) in various age between 22 to 70 years old. Patients treated with autologous adipose-derived MSCs implantation through catheterization. The laboratory analysis result of patients before and after MSCs application in 6 months were measured, include haemoglobin (Hb), leukocytes, erythrocyte sedimentation rate (ESR), protein and blood levels in urine, high sensitivity c-reactive protein (hsCRP), C3 and C4 complement, anti-nuclear antibodies (ANA) and anti-double stranded DNA (anti-dsDNA). MSCs are able to improve the performance of hemoglobin which statistically significant increased (p=0.002). MSCs are able to reduce the inflammatory as shown in the number of leukocytes (p=0.015) and ESR (p=0.031) which statistically significant decreased. MSCs can repair the renal function as shown in no presences of protein and blood in patient’s urine. MSCs are also able to augment the immune response as shown in hsCRP which statistically significant decreased (p<0.001), while C3 and C4 complements statistically significant increased (p<0.001). ANA and anti-dsDNA showed a negative result which means MSCs therapy may give a good response to heal the ADs.

Detecting joint inflammation by an LED-based photoacoustic imaging system: a feasibility study

Light-emitting diode (LED) light sources have recently been introduced to photoacoustic imaging (PAI). The LEDs enable a smaller footprint for PAI systems when compared to laser sources, thereby improving system portability and allowing for improved access. An LED-based PAI system has been employed to identify inflammatory arthritis in human hand joints. B-mode ultrasound (US), Doppler, and PAIs were obtained from 12 joints with clinically active arthritis, five joints with subclinically active arthritis, and 12 normal joints. The quantitative assessment of hyperemia in joints by PAI demonstrated statistically significant differences among the three conditions. The imaging results from the subclinically active arthritis joints also suggested that the LED-based PAI has a higher sensitivity to angiogenic microvascularity compared to US Doppler imaging. This initial clinical study on arthritis patients validates that PAI can be a potential imaging modality for the diagnosis of inflammatory arthritis.

Identification of genes and signaling pathways associated with the pathogenesis of juvenile spondyloarthritis

The aim of the present study was to identify key genes and signaling pathways associated with the pathogenesis of juvenile spondyloarthritis (JSA). The gene expression profile dataset GSE58667, including data from 15 human whole blood samples collected from 11 patients with JSA and four healthy controls, was analyzed to identify differentially expressed genes (DEGs) associated with disease characteristics. Additionally, Gene Ontology term and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses of the DEGs were performed. Protein‑protein, microRNA‑transcription factor and chemical‑gene interaction networks were constructed. A total of 326 DEGs, 196 upregulated and 130 downregulated, were identified. DEGs, including C‑X‑C motif chemokine ligand 5 (CXCL5), BCL2 interacting protein 3 like (BNIP3L), dual specificity phosphatase 5 (DUSP5) and tumor protein p53 (TP53) were enriched in functions associated with apoptosis, the cell cycle and immune responses. KEGG pathway enrichment analysis revealed that pathways associated with inflammation and the mitogen‑activated protein kinase 1 (MAPK) signaling pathway were the most enriched by DEGs. The results of the present study indicated that the MAPK signaling pathway and four genes, including CXCL5, BNIP3L, DUSP5 and TP53, may be implicated in the pathogenesis of JSA.

Efficacy of a Work Disability Prevention Program for People with Rheumatic and Musculoskeletal Conditions: A Single-Blind Parallel-Arm Randomized Controlled Trial

OBJECTIVE

Work disability rates are high among people with rheumatic and musculoskeletal conditions. Effective disability preventive programs are needed. We examined the efficacy of a modified vocational rehabilitation approach delivered by trained occupational therapists and physical therapists on work limitation and work loss over 2 years among people with rheumatic and musculoskeletal conditions.

METHODS

Eligibility criteria for this single-blind, parallel-arm randomized trial included ages 21-65 years, 15 or more hours/week employment, a self-reported doctor-diagnosed rheumatic or musculoskeletal condition, and concern about staying employed. The intervention consisted of a 1.5-hour meeting, an action plan, written materials on employment supports, and telephone calls at 3 weeks and 3 months. Control group participants received the written materials. The primary outcome was the Work Limitations Questionnaire (WLQ) output job demand subscale. The secondary outcome was work loss. Intent-to-treat analyses were performed.

RESULTS

Between October 2011 and January 2014, 652 individuals were assessed for eligibility. A total of 287 participants were randomized: 143 intervention and 144 control participants. In total, 264 participants (92%) completed 2-year data collection. There was no difference in the mean ± SD WLQ change scores from baseline to 2-year followup (-8.6 ± 1.9 intervention versus -8.3 ± 2.2 control; P = 0.93). Of the 36 participants who experienced permanent work loss at 2 years, 11 (8%) were intervention participants and 25 (18%) control participants (P = 0.03).

CONCLUSION

The intervention did not have an effect on work limitations but reduced work loss. The intervention can be delivered by trained rehabilitation therapists.

Contacting of authors by systematic reviewers: protocol for a cross-sectional study and a survey

BACKGROUND

Synthesizing outcomes of underreported primary studies can pose a serious threat to the validity of outcomes and conclusions of systematic reviews. To address this problem, the Cochrane Collaboration recommends reviewers to contact authors of eligible primary studies to obtain additional information on poorly reported items. In this protocol, we present a cross-sectional study and a survey to assess (1) how reviewers of new Cochrane intervention reviews report on procedures and outcomes of contacting of authors of primary studies to obtain additional data, (2) how authors reply, and (3) the consequences of these additional data on the outcomes and quality scores in the review. All research questions and methods were pilot tested on 2 months of Cochrane reviews and were subsequently fine-tuned.

METHODS FOR THE CROSS-SECTIONAL STUDY

Eligibility criteria are (1) all new (not-updates) Cochrane intervention reviews published in 2016, (2) reviews that included one or more primary studies, and (3) eligible interventions refer to contacting of authors of the eligible primary studies included in the review to obtain additional research data (e.g., information on unreported or missing data, individual patient data, research methods, and bias issues). Searching for eligible reviews and data extraction will be conducted by two authors independently. The cross-sectional study will primarily focus on how contacting of authors is conducted and reported, how contacted authors reply, and how reviewers report on obtained additional data and their consequences for the review.

METHODS FOR THE SURVEY

The same eligible reviews for the cross-sectional study will also be eligible for the survey. Surveys will be sent to the contact addresses of these reviews according to a pre-defined protocol. We will use Google Forms as our survey platform. Surveyees are asked to answer eight questions. The survey will primarily focus on the consequences of contacting authors of eligible primary studies for the risk of bias and Grading of Recommendations, Assessment, Development and Evaluation scores and the primary and secondary outcomes of the review.

DISCUSSION

The findings of this study could help improve methods of contacting authors and reporting of these procedures and their outcomes. Patients, clinicians, researchers, guideline developers, research sponsors, and the general public will all be beneficiaries.

Fostering needs assessment and access to medical rehabilitation for patients with chronic disease and endangered work ability: protocol of a multilevel evaluation on the effectiveness and efficacy of a CME intervention for general practitioners

BACKGROUND

Studies show that endangered work ability (EWA) can be maintained or restored through medical rehabilitation (MR). For patients, general practitioners (GP) represent an important point of access to MR in outpatient care. However, many different barriers and shortcomings hinder GPs in both timely detection of the need for MR and the recognition of its potentials for their EWA-patients. These are necessary if GPs are to adequately inform patients about MR options and successfully support applications for MR. This study describes the evaluation of a continuing medical education (CME) module designed to improve rehabilitation-related practical performance of GPs regarding a) subjective satisfaction of GPs with the CME module, b) stability of attitudes and knowledge over time regarding rehabilitation, and c) subjective and objective changes in MR-related competencies needed to support MR applications.

METHODS

This study is an open, non-randomised, pre-post-intervention study. The intervention involves a CME module for GPs (n = 1365) in the German state of Saxony-Anhalt on the topic of medical rehabilitation in connection with the federal German pension fund (Deutsche Rentenversicherung). The module will be initially held as regularly scheduled meetings in moderated GP quality circles (QC), and then offered as a written self-study unit. At the end it will be evaluated by the GPs. The study's primary focus is on the organizational practice as measured by the number of approved MR applications supported by medical reports submitted by the participating GPs in the 6 months before and 6 months after the CME module. Other study aims involve measuring self-perceived competencies of GPs, as well as their attitudes towards and knowledge of rehabilitation (both upon completing the CME and 6 months later). In addition, the level of satisfaction with the CME module will be analysed among participating GPs and QC moderators (as CME facilitators).

DISCUSSION

Implementing targeted CME on complex topics such as those involving barriers is possible, even promising, when using QCs and their moderators. Of particular importance is how aware moderating physicians are of the relevance of MR need detection and access.

ETHICS AND DISSEMINATION

The ethics committee of the Martin-Luther-Universität Halle-Wittenberg has registered this study under the number 2014-13. The study will be reported on in peer-reviewed journals and at national and international conferences. The results will be available to current and future initiatives aiming to improve detection of MR need and making MR accessible to EWEC patients needing such support to minimize the effects of chronic disease on their livess.

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.

A systematic review of the barriers affecting medication adherence in patients with rheumatic diseases

Medication adherence is a crucial part in the management of rheumatic diseases, especially with many such patients requiring long-term medications. In this paper, we aim to systematically review the literature for the factors associated with medication adherence in the rheumatic patient population. We carried out a systematic literature search using PubMed^®, PsychInfo^® and Embase ^® with relevant keywords and employed the PRISMA^® criteria. We included English peer-reviewed articles that studied the factors affecting medication adherence in patients with rheumatic diseases, which were assessed by two independent reviewers. Hand searches were conducted and relevant factors were extracted and classified using the World Health Organization (WHO)'s five dimensions of medication adherence. A simple diagram was drawn to summarise the factors extracted. 1977 articles were identified and reviewed and 90 articles were found to be relevant. A total of 17 factors and 38 sub-factors were identified and categorized based on the WHO's five dimensions of medication adherence. A hand model for medication adherence was developed to succinctly summarise these dimension to remind clinicians the importance of medication adherence in daily practice. We conducted a systematic review on the various factors including patient, therapy, condition, health system and socioeconomic-related factors that affected medication adherence in rheumatic patients. We found 17 factors and 38 sub-factors that affected medication adherence in this population. This systematic review can facilitate future focused research in unexplored dimensions.

Physical activity and exercise for chronic pain in adults: an overview of Cochrane Reviews

BACKGROUND

Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning.Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure.

OBJECTIVES

To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions.

METHODS

We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence.We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3) psychological function, (4) quality of life, (5) adherence to the prescribed intervention, (6) healthcare use/attendance, (7) adverse events, and (8) death.Due to the limited data available, we were unable to directly compare and analyse interventions, and have instead reported the evidence qualitatively.

MAIN RESULTS

We included 21 reviews with 381 included studies and 37,143 participants. Of these, 264 studies (19,642 participants) examined exercise versus no exercise/minimal intervention in adults with chronic pain and were used in the qualitative analysis.Pain conditions included rheumatoid arthritis, osteoarthritis, fibromyalgia, low back pain, intermittent claudication, dysmenorrhoea, mechanical neck disorder, spinal cord injury, postpolio syndrome, and patellofemoral pain. None of the reviews assessed 'chronic pain' or 'chronic widespread pain' as a general term or specific condition. Interventions included aerobic, strength, flexibility, range of motion, and core or balance training programmes, as well as yoga, Pilates, and tai chi.Reviews were well performed and reported (based on AMSTAR), and included studies had acceptable risk of bias (with inadequate reporting of attrition and reporting biases). However the quality of evidence was low due to participant numbers (most included studies had fewer than 50 participants in total), length of intervention and follow-up (rarely assessed beyond three to six months). We pooled the results from relevant reviews where appropriate, though results should be interpreted with caution due to the low quality evidence. Pain severity: several reviews noted favourable results from exercise: only three reviews that reported pain severity found no statistically significant changes in usual or mean pain from any intervention. However, results were inconsistent across interventions and follow-up, as exercise did not consistently bring about a change (positive or negative) in self-reported pain scores at any single point. Physical function: was the most commonly reported outcome measure. Physical function was significantly improved as a result of the intervention in 14 reviews, though even these statistically significant results had only small-to-moderate effect sizes (only one review reported large effect sizes). Psychological function and quality of life: had variable results: results were either favourable to exercise (generally small and moderate effect size, with two reviews reporting significant, large effect sizes for quality of life), or showed no difference between groups. There were no negative effects. Adherence to the prescribed intervention: could not be assessed in any review. However, risk of withdrawal/dropout was slightly higher in the exercising group (82.8/1000 participants versus 81/1000 participants), though the group difference was non-significant. Healthcare use/attendance: was not reported in any review. Adverse events, potential harm, and death: only 25% of included studies (across 18 reviews) actively reported adverse events. Based on the available evidence, most adverse events were increased soreness or muscle pain, which reportedly subsided after a few weeks of the intervention. Only one review reported death separately to other adverse events: the intervention was protective against death (based on the available evidence), though did not reach statistical significance.

AUTHORS' CONCLUSIONS

The quality of the evidence examining physical activity and exercise for chronic pain is low. This is largely due to small sample sizes and potentially underpowered studies. A number of studies had adequately long interventions, but planned follow-up was limited to less than one year in all but six reviews.There were some favourable effects in reduction in pain severity and improved physical function, though these were mostly of small-to-moderate effect, and were not consistent across the reviews. There were variable effects for psychological function and quality of life.The available evidence suggests physical activity and exercise is an intervention with few adverse events that may improve pain severity and physical function, and consequent quality of life. However, further research is required and should focus on increasing participant numbers, including participants with a broader spectrum of pain severity, and lengthening both the intervention itself, and the follow-up period.
