Effect evaluation of a self-management programme for employees with complaints of the arm, neck or shoulder: a randomised controlled trial

The effect of exercise and education combination via telerehabilitation in patients with chronic neck pain: A randomized controlled trial

BACKGROUND

A limited number of studies have investigated the effect of telerehabilitation in individuals with chronic neck pain (CNP).

OBJECTIVE

The study aimed to evaluate the effectiveness of holistic exercise and education combination via telerehabilitation on pain, disability, kinesiophobia, exercise adherence, quality of life and patient satisfaction in individuals with CNP.

METHODS

A two-armed, randomized controlled study was conducted with 40 participants with CNP. Patients were randomized into two groups: Telerehabilitation (TR) (n = 20) and Standard Rehabilitation (SR) (n = 20). The TR group was provided with exercise and education videos online. The same protocol was given to the SR group in the clinical setting. Patients were evaluated at baseline and after eight weeks of intervention. Satisfaction and usability levels of the TR group were assessed at week 8.

RESULTS

TR group demonstrated better improvement in function, quality of life (including bodily pain, general health, social function), kinesiophobia and exercise adherence. The TR group was not superior to the SR group in pain and other quality-of-life subscores. A vast majority of the TR group had high satisfaction and usability.

CONCLUSION

Comprehensive rehabilitation via TR increases satisfaction and participation in patients with CNP. Besides, TR provides more positive effects on function and kinesiophobia. Further studies should focus on the impact of telerehabilitation on pain and quality of life in CNP with a long-term follow-up.

Supervised Exercise Therapy Reduces Presenteeism to Greater Extent Than Unsupervised Self-Care in Workers with Musculoskeletal Pain: a Systematic Review and Meta-Analysis

PURPOSE

Presenteeism is defined as the loss of work productivity due to health issues in workers, which can be measured subjectively. This study aimed to compare the effectiveness of supervised exercise therapy and unsupervised self-care in reducing presenteeism in workers with musculoskeletal disorders.

METHODS

PubMed, Embase, and Cochrane Library were searched for various keywords from their inception to January 2023. Two examiners independently assessed the eligibility of studies: (1) studies involving workers suffering from musculoskeletal pain, (2) those involving supervised exercise therapy intervention with interactive communication, and (3) those in which the comparison group was subjected to interventions other than supervised exercise therapy, and (4) those including patient-reported outcome measures of presenteeism or work productivity or ability. Standardized mean differences (SMD) were calculated using a random effects model, with higher scores indicating reduced presenteeism in the intervention group compared with that in the comparison group. The GRADE assesses the overall certainty of the evidence.

RESULTS

Only the short-term effects of interventions on presenteeism could be obtained using four studies. The intervention group showed statistically significant short-term effects on presenteeism compared with the comparison group (p < 0.001; SMD, 0.52; 95% confidence interval, 0.27-0.77). The GRADE score was downgraded by two levels from high to low due to concerns for indirectness.

CONCLUSIONS

Although the certainty of the evidence was low, it was assumed that supervised exercise therapy was more effective than unsupervised self-care in reducing presenteeism in workers with musculoskeletal disorders.

Measuring, Analyzing, and Presenting Work Productivity Loss in Randomized Controlled Trials: A Scoping Review

OBJECTIVES

This study aimed to conduct a scoping review of randomized controlled trials (RCTs) and investigate which work productivity loss outcomes were measured in these RCTs, how each outcome was measured and analyzed, and how the results for each outcome were presented.

METHODS

A systematic search was conducted from January 2010 to April 2020 from 2 databases: PubMed and Cochrane Central Register of Controlled Trials. Data on country, study population, disease focus, sample size, work productivity loss outcomes measured (absenteeism, presenteeism, employment status changes), and methods used to measure, report, and analyze each work productivity loss outcome were extracted and analyzed.

RESULTS

We found 435 studies measuring absenteeism or presenteeism, of which 155 studies (35.6%) measured both absenteeism and presenteeism and were included in our final review. Only 9 studies also measured employment status changes. The most used questionnaire was the Work Productivity and Activity Impairment Questionnaire. The analysis of absenteeism and presenteeism data was mostly done using regression models (n = 98, n = 98, respectively) for which a normal distribution was assumed (n = 77, n = 89, respectively). Absenteeism results were most often presented in time whereas presenteeism was commonly presented using a percent scale or score.

CONCLUSIONS

There is a lack of consensus on how to measure, analyze, and present work productivity loss outcomes in RCTs published in the past 10 years. The diversity of measurement, analysis, and presentation methods used in RCTs may make comparability challenging. There is a need for guidelines providing recommendations to standardize the comprehensiveness and the appropriateness of methods used to measure, analyze, and report work productivity loss in RCTs.

Rethinking long-term condition management: An actor-level framework

To understand the complexities of managing long-term conditions and develop appropriate responses, micro-, meso- and macrolevels must be considered. However, these levels have not been combined in a single analytical framework of long-term condition management (LTCM). This article aims to describe a framework of LTCM practice and research that combines societal levels and key agents. The actor-level framework, based on the works of Abram De Swaan and Randall Collins, provides a broader understanding of LTCM as an interdisciplinary research field compared to previous contributions. The framework has three main advantages. First, it encourages knowledge production across levels and actors that address the complexity of long-term illness management. Second, it broadens the scope of LTCM as an interdisciplinary research field and practice field. Finally, it facilitates the integration of knowledge production from different disciplines and research traditions. The framework could stimulate interdisciplinary research collaboration to enhance knowledge of processes and interactions influencing the lives of individuals with long-term conditions.

A scoping review to ascertain the parameters for an evidence synthesis of psychological interventions to improve work and wellbeing outcomes among employees with chronic pain

Background: Psychological interventions have mixed effects on improving employee outcomes, partly due to significant variability across studies and a lack of focus on mechanisms of action. This scoping review reports on the parameters of these interventions and examines intervention content to bring clarity to this heterogeneous topic area and direct future systematic review work.

Method: Six databases were searched (Cinahl, Cochrane, Embase, Medline, PsychINFO and Web of Science) from April 2010 to August 2020, and a grey literature search was undertaken. Screening was undertaken independently by two authors. The results summarised country, participant and employment characteristics, psychological interventions and work, health and wellbeing outcomes. 10% of the papers were analysed to determine the feasibility of coding intervention descriptions for theory and behaviour change technique (BCT) components.

Results: Database searches yielded 9341 titles, of which 91 studies were included. Most studies were conducted in Europe (78%) and included males and females (95%) ranging in age from 31-56.6 years although other demographic, and employment information was lacking. Musculoskeletal pain was common (87%). Psychological interventions commonly included cognitive behavioural therapy (30%) and education (28%). Most studies employed a randomised control trial design (64%). Over half contained a control group (54%). Interventions were delivered in mostly healthcare settings (72%) by health professionals. Multiple outcomes were often reported, many of which involved measuring sickness absence and return-to-work (62%) and pain and general health (53%). Within the feasibility analysis, most papers met the minimum criteria of containing one paragraph of intervention description, but none explicitly mentioned theory or BCTs.

Conclusion: Psychological interventions for employees with chronic pain vary in their nature and implementation. We have shown scoping reviews can be used to assess the feasibility of applying tools from health psychology to identify the content of these interventions in future systematic review work to improve intervention development.

Interventions on cognitions and perceptions that influence work participation of employees with chronic health problems: a scoping review

BACKGROUND

Cognitions and perceptions, such as motivation and return to work (RTW) expectations, can influence work participation of employees with chronic health problems. This makes these cognitions and perceptions important factors for occupational health professionals to intervene upon in order to increase work participation. There is, however, no overview of interventions that influence these factors and are aimed at increasing work participation. Therefore, the purpose of this scoping review is to explore available interventions that are focused on cognitions and perceptions of employees with chronic health problems and aimed at increasing work participation.

METHODS

A scoping review was carried out following the framework of Arksey and O'Malley. Ovid MEDLINE and PsycINFO were searched for original papers published between January 2013 and June 2020. We included studies that describe interventions that focus on at least one of ten cognitions and perceptions and on work participation. The risk of bias of the studies included was assessed using quality assessment tools from the Joanna Briggs Institute.

RESULTS

In total, 29 studies were identified that studied interventions aimed at changing at least one of ten cognitions and perceptions in order to change work participation. The interventions that were included mainly focused on changing recovery and RTW expectations, self-efficacy, feelings of control, perceived health, fear-avoidance beliefs, perceived work-relatedness of the health problem, coping strategies and catastrophizing. No interventions were found that focused on changing motivation or on optimism/pessimism. Four interventions were judged as effective in changing coping, self-efficacy, fear-avoidance beliefs, or perceived work-relatedness and work participation according to results of randomized controlled trials.

CONCLUSIONS

This review provides an overview of interventions that focus on changing cognitions and perceptions and work participation. Evidence was found for four effective interventions focused on changing these factors and increasing work participation. Occupational health professionals may use the overview of interventions to help employees with chronic health problems to increase their work participation.

Effectiveness and characteristics of interventions to improve work participation in adults with chronic physical conditions: a systematic review

PURPOSE

Chronic physical conditions often negatively affect work participation. The objective of this systematic review is to investigate the effectiveness and characteristics of vocational rehabilitation interventions for people with a chronic physical condition.

METHODS

Searches in five databases up to April 2020 identified 30 studies meeting our inclusion criteria. Two reviewers independently assessed and extracted data. The Grading of Recommendation, Assessment, Development and Evaluation (GRADE) framework was used to evaluate quality of evidence for three outcome measures related to work participation.

RESULTS

All vocational rehabilitation interventions consisted of multiple components, but their characteristics varied widely. Analysis of 22 trials yielded a moderate positive effect with moderate certainty of interventions on work status; analysis of five trials with low risk of bias showed a large positive effect with moderate certainty (risk ratio 1.33 and 1.57, respectively). In addition, in eight studies we found a moderate to small positive effect with low certainty on work attitude (standardized mean difference = 0.59 or 0.38, respectively). We found no effect on work productivity in nine studies.

CONCLUSION

The systematic review of the literature showed positive effects of vocational rehabilitation interventions on work status and on work attitude; we found no effect on work productivity.Implications for rehabilitationIn rehabilitation, addressing work participation of persons with a chronic physical condition using targeted interventions is beneficial to improve or sustain work participation, irrespective of the intervention characteristics and diagnosis.Interventions that include multiple components and offer individual support, whether or not combined with group sessions, are likely to be more effective in improving work participation in persons with a chronic physical condition.The overview of vocational interventions in this systematic review may assist healthcare professionals in making informed decisions as to which intervention to provide.Vocational rehabilitation, as well as studies on work participation in chronic disease, should include a long follow-up period to explore if work participation is sustainable and contributes to health and wellbeing.

The effects of integrating work-related factors and improving cooperation in musculoskeletal physical therapy practice: protocol for the 'WORK TO BE DONE' cluster randomised controlled trial

BACKGROUND

Musculoskeletal disorders (MSDs) are the primary cause of disability worldwide and a major societal burden. Recent qualitative research found that although a patient's work is considered important, physical therapists take work participation insufficiently into account as a determining factor in the treatment of patients with MSDs. Therefore, the aim of this study is to improve the effectiveness of physical therapy (in primary healthcare) with respect to the work participation of employees with MSDs by increasing the knowledge and skills of generalist physical therapists and by improving the collaboration between generalist physical therapists and physical therapists specialised in occupational health.

METHODS/DESIGN

This trial is a two-arm non-blinded cluster randomised controlled trial. Working patients with MSDs visiting a physical therapy practice are the target group. The control group will receive normal physical therapy treatment. The intervention group will receive treatment from a physical therapist with more knowledge about work-related factors and skills in terms of integrating work participation into the patients' care. Data are gathered at baseline (T0), at four months (T1) and eight months (T2) follow-up. Most outcomes will be assessed with validated patient-reported questionnaires. Primary outcomes are the limitations in specific work-related activities and pain during work. Secondary outcomes include limitations in general work-related activities, general pain, quality of life, presenteeism, sick leave (absenteeism), estimated risk for future work disability, work-related psychosocial risk factors, job performance, and work ability. Based on a sample size calculation we need to include 221 patients in each arm (442 in total). During data analysis, each outcome variable will be analysed independently at T1 and at T2 as a dependent variable using the study group as an independent variable. In addition to the quantitative evaluation, a process evaluation will be performed by interviewing physical therapists as well as patients.

DISCUSSION

The trial is expected to result in a more effective physical therapy process for working patients with MSDs. This will lead to a substantial reduction of costs: lower costs thanks to a more effective physical therapy process and lower costs due to less or shorter sick leave and decreased presenteeism.

Resilience and return-to-work pain interventions: systematic review

BACKGROUND

Resilience is a developing concept in relation to pain, but has not yet been reviewed in return-to-work (RTW) contexts.

AIMS

To explore the role of resilience enhancement in promoting work participation for chronic pain sufferers, by reviewing the effectiveness of existing interventions.

METHODS

Resilience was operationalized as: self-efficacy, active coping, positive affect, positive growth, positive reinforcement, optimism, purpose in life and acceptance. Five databases were searched for randomized controlled trials (RCTs) whose interventions included an element of resilience designed to help RTW/staying at work for chronic pain sufferers. Study appraisal comprised the Cochrane risk of bias (RoB) tool and additional quality assessment. Findings were synthesized narratively and between-group differences of outcomes were reported. Heterogeneous PICO (population, intervention, comparator, outcome) elements precluded meta-analysis.

RESULTS

Thirty-four papers from 24 RCTs were included. Interventions varied; most were multidisciplinary, combining behavioural, physical and psychological pain management and vocational rehabilitation. Four found RTW/staying at work improved with intensive multidisciplinary interventions compared with less intensive, or no, treatment. Of these, one had low RoB; three scored poorly on allocation concealment and selective outcome reporting. Four trials had mixed results, e.g. interventions enabling reduced sick leave for people on short-term not long-term leave; 16 showed no improvement. Five trials reported resilience outcomes were improved by interventions but these were not always trials in which RTW improved.

CONCLUSIONS

Effectiveness of resilience interventions for chronic pain sufferers on RTW is uncertain and not as helpful as anticipated. Further agreement on its conceptualization and terminology and that of RTW is needed.

Education as a strategy for managing occupational-related musculoskeletal pain: a scoping review

BACKGROUND

Musculoskeletal (MSK) pain is the primary contributor to disability worldwide. There is a growing consensus that MSK pain is a recurrent multifactorial condition underpinned by health and lifestyle factors. Studies suggest that education on work-related pain and individualised advice could be essential and effective for managing persistent MSK pain.

OBJECTIVE

The objective of this scoping review was to map the existing educational resources for work-related MSK (WRMSK) pain, and the effects of implementing educational strategies in the workplace on managing WRMSK pain.

METHODS

This scoping review assessed original studies that implemented and assessed education as a strategy to manage WMSK pain. Literature search strategies were developed using thesaurus headings (ie, MeSH and CINAHL headings) and free-text search including words related to MSK in an occupational setting. The search was carried out in PubMed, CINAHL, Cochrane Library and Web of Science in the period 12-14 February 2019.

RESULTS

A total of 19 peer-reviewed articles were included and the study design, aim and outcomes were summarised. Of the 19 peer-reviewed articles, 10 randomised controlled trial (RCT) studies assessed the influence of education on work-related MSK pain. Many studies provided a limited description of the education material and assessed/used different methods of delivery. A majority of studies concluded education positively influences work-related MSK pain. Further, some studies reported additive effects of physical activity or ergonomic adjustments.

CONCLUSIONS

There is a gap in knowledge regarding the best content and delivery of education of material in the workplace. Although beneficial outcomes were reported, more RCT studies are required to determine the effects of education material as compared with other interventions, such as exercise or behavioural therapy.

A systematic review of interventions to retain chronically ill occupationally active employees in work: can findings be transferred to cancer survivors?

Background: Interventions supporting occupationally active cancer survivors to retain work and prevent adverse work outcomes, beyond return to work, are scarce. As lessons may be learned from interventions that have been evaluated in working employees with other chronic diseases than cancer, the objective of this review was to summarize the characteristics of these interventions. Material and methods: Studies were identified through computerized PubMed, EMBASE and PsycINFO searches, without any language or year of publication restrictions. Randomized controlled trials were included if they evaluated the effectiveness of interventions to retain chronically ill occupationally active employees in work. Two authors independently extracted data from each study and assessed the risk of bias. Results: The search identified 536 unique studies, of which 18 met the inclusion criteria. All included studies had a low risk of bias. (Psycho-)educational interventions for chronically ill employees to retain work were evaluated in two studies, physical interventions in three studies, vocational/work-related interventions in five studies, and multidisciplinary interventions in eight studies. Vocational/work-related and multidisciplinary interventions, and the involvement of professional trainers, showed the most promising effects in retaining employees. However, small sample sizes may have caused imprecise effect estimates. Conclusion: Based on studies focusing on occupationally active employees with other chronic diseases than cancer, it is advised that working cancer survivors should be offered tailored interventions, by skilled trainers, to sustain their employability. Shared goal setting, with relevant stakeholders, and vocational components should be included, potentially as part of a multidisciplinary intervention.

Interventions Developed with the Intervention Mapping Protocol in Work Disability Prevention: A Systematic Review of the Literature

Purposes Intervention mapping (IM) is a protocol for developing effective behavior change interventions. It has been used for 10 years to develop work disability prevention (WDP) interventions, but it is not known to what extent and with what success. The main objective of this study was to review the effectiveness of these interventions. Secondary objectives were to review their fidelity to the IM protocol, their theoretical frameworks and their content. Methods A search strategy was conducted in MEDLINE, Web of Science, PsycINFO, Pascal, Francis, and BDSP. All titles and abstracts were reviewed. A standardized extraction form was developed. All included studies were reviewed by two reviewers blinded to each other. Results Eight WDP interventions were identified aimed at return to work (RTW; n = 6) and self-management at work (n = 2). RTW interventions targeted workers with stress-related mental disorders (n = 1), low back pain (n = 1), musculoskeletal disorders (n = 1), cancer (n = 2) and gynecological surgery (n = 1). The fidelity to the IM protocol was weaker for the participatory planning group. Matrices of change, change methods, and applications were systematically reported. The main theoretical frameworks used were the attitude-social influence-self efficacy model (n = 4) and the theory of planned behavior (n = 2). Half of the interventions included a workplace component (n = 4). Two interventions were reported as effective, and one partially effective. Conclusion The IM protocol is used in WDP since 2007. The participative dimension appears underused. Few theoretical frameworks were used. Implications are to better consider the stakeholders involvement, and mobilize theoretical frameworks with greater attempts to intervene on the work environment.

Behaviour change techniques applied in interventions to enhance physical activity adherence in patients with chronic musculoskeletal conditions: A systematic review and meta-analysis

OBJECTIVE

To identify Behaviour Change Techniques (BCTs) applied in interventions to enhance physical activity (PA) adherence in patients with chronic musculoskeletal conditions and to investigate the effectiveness of these interventions in increasing PA adherence.

METHODS

A systematic search of seven databases was conducted. We included (cluster/quasi-) randomised controlled trials comparing behaviour change interventions to no/placebo/minimal interventions or usual care and involving at least a three-month post-intervention follow-up. Methodological quality was assessed, study characteristics and BCTs were narratively summarised and a meta-analysis was conducted.

RESULTS

Across 22 included studies, we coded 8-18 BCTs (mean = 11.2) in intervention and 0-12 (mean = 3.5) in control groups. Common BCTs were "graded tasks", "goal setting", "self-monitoring", "problem solving" and "feedback". Meta-analyses of 17 studies revealed a small medium-term effect (3-6 months post-intervention, standardised mean difference (SMD) = 0.20, 95% CI 0.08-0.33) and no long-term effect (7-12 months post-intervention, SMD = 0.13, 95% CI -0.02 to 0.28). Subgroup analysis yielded a higher effect (SMD = 0.29, 95% CI 0.19-0.40) for interventions using a greater number of BCTs.

CONCLUSION

There is moderate quality evidence that interventions using BCTs are effective to enhance medium-term physical activity adherence.

PRACTICE IMPLICATION

While superiority of single BCTs was not shown, it is likely that using more BCTs results in better adherence.

A systematic review on workplace interventions to manage chronic musculoskeletal conditions

BACKGROUND AND PURPOSE

A review to investigate whether there are effective workplace interventions that manage chronic musculoskeletal disorders.

METHODS

The literature search included published articles between 2008 and 2017. The databases used in this search were MEDLINE, Scopus, CINAHL, AMED, PsycINFO, Academic Search Complete, Cochrane, and PEDro. A limited search on websites for relevant grey literature was also conducted.

RESULTS

The review included 12 studies that investigated effectiveness of a specific strength exercise programme or interventions provided by health professionals at the workplace when compared with controls or interventions not at the workplace. Seven studies were classified as high quality (>85% of criteria met) and five studies were classified as acceptable. Studies were heterogeneous preventing a meta-analysis. No intervention was clearly superior to another.

DISCUSSION

There was some consistency in the results of the selected studies, suggesting that workplace interventions such as high-intensity strength exercises and/or integrated health care can decrease pain and symptoms for employees who experience long-term musculoskeletal disorders. However, the current research is limited.

The effectiveness of generic self-management interventions for patients with chronic musculoskeletal pain on physical function, self-efficacy, pain intensity and physical activity: A systematic review and meta-analysis

Generic self‐management programs aim to facilitate behavioural adjustment and therefore have considerable potential for patients with chronic musculoskeletal pain. Our main objective was to collect and synthesize all data on the effectiveness of generic self‐management interventions for patients with chronic musculoskeletal pain in terms of physical function, self‐efficacy, pain intensity and physical activity. Our secondary objective was to describe the content of these interventions, by means of classification according to the Behaviour Change Technique Taxonomy. We searched PubMed, CENTRAL, Embase and Psycinfo for eligible studies. Study selection, data extraction and risk of bias were assessed by two researchers independently. Meta‐analyses were only performed if the studies were sufficiently homogeneous and GRADE was used to determine the quality of evidence. We identified 20 randomized controlled trials that compared a self‐management intervention to any type of control group. For post‐intervention results, there was moderate quality evidence of a statistically significant but clinically unimportant effect for physical function and pain intensity, both favouring the self‐management group. At follow‐up, there was moderate quality evidence of a small clinically insignificant effect for self‐efficacy, favouring the self‐management group. All other comparisons did not indicate an effect. Classification of the behaviour change techniques showed large heterogeneity across studies. These results indicate that generic self‐management interventions have a marginal benefit for patients with chronic musculoskeletal pain in the short‐term for physical function and pain intensity and for self‐efficacy in the long‐term, and vary considerably with respect to intervention content.

Significance

This study contributes to a growing body of evidence that generic self‐management interventions have limited effectiveness for patients with chronic musculoskeletal pain. Furthermore, this study has identified substantial differences in both content and delivery mode across self‐management interventions.

Experiences of Participants in a Self-Management Program for Employees with Complaints of the Arm, Neck or Shoulder (CANS): A Mixed Methods Study

Purpose To investigate the experiences of participants of a self-management program for employees with complaints of the arm, neck or shoulder (CANS). The program consisted of six group sessions combined with an eHealth module. Methods Semi-structured interviews with the first 31 consecutive participants of the intervention group participating in a randomized controlled trial. Participants were interviewed after their last group session. Semi-structured interviews were guided by an interview guide and audio-recorded. Data were analyzed using thematic analysis and the emerging themes were discussed. All participants in the intervention group were asked about their experiences with a questionnaire at three (n = 58) and 12-months (n = 53) follow-up. Results Most participants appreciated the diversity of the program and benefited from the interaction with their peers. The eHealth module, although not used by everyone, was generally experienced as positive, especially the section with the physical exercises. Participants obtained more insight into their complaints and increased awareness, which contributed to the acceptance of and coping with the complaints. There was also criticism about the content of the program and the lack of a follow-up session. Results of the questionnaires showed that participants had a high level of satisfaction. Conclusions In general, the intervention fitted the needs of employees with CANS. Participants obtained more knowledge and insight into their complaints, as well as increased awareness; all this contributed to a behavioral change and improved coping. Many participants made changes at work and during their leisure time, whereas some felt that continuing their 'changed' behavior would be a challenge.

Sustaining Work Participation Across the Life Course

Introduction Many disability prevention strategies are focused on acute injuries and brief illness episodes, but there will be growing challenges for employers to manage circumstances of recurrent, chronic, or fluctuating symptoms in an aging workforce. The goal of this article is to summarize existing peer-review research in this area, compare this with employer discourse in the grey literature, and recommend future research priorities. Methods The authors participated in a year-long sponsored collaboration that ultimately led to an invited 3-day conference, "Improving Research of Employer Practices to Prevent Disability", held October 14-16, 2015, in Hopkinton, Massachusetts, USA. The collaboration included a topical review of the scientific and industry literature, group discussion to identify key areas and challenges, drafting of initial documents, and feedback from peer researchers and a special panel of experts with employer experience. Results Cancer and mental illness were chosen as examples of chronic or recurring conditions that might challenge conventional workplace return-to-work practices. Workplace problems identified in the literature included fatigue, emotional exhaustion, poor supervisor and co-worker support, stigma, discrimination, and difficulties finding appropriate accommodations. Workplace intervention research is generally lacking, but there is preliminary support for improving workplace self-management strategies, collaborative problem-solving, and providing checklists and other tools for job accommodation, ideas echoed in the literature directed toward employers. Research might be improved by following workers from an earlier stage of developing workplace concerns. Conclusions Future research of work disability should focus on earlier identification of at-risk workers with chronic conditions, the use of more innovative and flexible accommodation strategies matched to specific functional losses, stronger integration of the workplace into on-going rehabilitation efforts, and a better understanding of stigma and other social factors at work.

Sick leave in workers with arm, neck and/or shoulder complaints; defining occurrence and discriminative trajectories over a 2-year time period

OBJECTIVES

Impediments due to complaints of non-traumatic arm, neck and/or shoulder (CANS) during work often leads to consultation in primary care. This study examines the occurrence of sick leave among workers with new CANS, and evaluates sick leave trajectories and their characteristics.

METHODS

This prospective 2-year cohort study included workers with a new CANS presenting in general practice. Participants filled out postal questionnaires on sick leave at 6-monthly intervals. Latent class growth mixture modelling was used to identify distinct trajectories of sick leave. Multinomial regression analyses identified characteristics of the subgroups.

RESULTS

During follow-up, of the 533 participants 190 reported at least one episode of sick leave due to CANS. Three sick leave trajectories were distinguished: (1) 'low-risk' trajectory (n=366), with a constant low probability over time; (2) 'intermediate risk' trajectory, with a high probability at first consultation followed by a steep decrease in probability of sick leave (n=122); (3) 'high-risk' trajectory (n=45), with a constant high probability of sick leave. Compared to the 'low-risk' trajectory, the other trajectories were characterised by more functional limitations, less specific diagnoses, more work-related symptoms and low coworker support. Specific for the 'high-risk' subgroup were more recurrent symptoms, more musculoskeletal comorbidity, high score on somatisation and low score on job demands.

CONCLUSIONS

Three trajectories of sick leave were distinguished, graded from favourable to unfavourable. Several complaint-related and work-related factors and somatisation contributed modestly to identify an unfavourable trajectory of sick leave when presenting in primary care with CANS.
