Functional Impairments and Work-Related Outcomes in Breast Cancer Survivors: A Systematic Review

Purpose Work participation after breast cancer treatment is generally negatively affected. Occupational health professionals might improve work-related outcomes by bridging the gap between sick-listed employees’ levels of functioning and work demands. To aid them in this task, this review explored the association between functional impairments and work-related outcomes in breast cancer survivors. Methods Publications from January 2000–March 2016 were identified through five online databases (i.e. Pubmed, EMBASE, PsycINFO, CINAHL and the Cochrane Library). Quantitative and qualitative studies were included if they focused on functional impairments and work-related outcomes in breast cancer survivors. Two reviewers independently selected studies, extracted data and performed quality assessment. Results The search identified 998 studies, of which 20 studies met eligibility criteria. Impairments in physical functioning negatively affected return to work (RTW) and work ability in quantitative and qualitative studies. Studies measuring cognitive functioning with tests found no association with work-related outcomes, whereas the results of studies using self-reported measures were ambiguous. Social functioning was less commonly investigated and findings differed across work-related outcomes. Emotional functioning was not associated with work-related outcomes in quantitative studies, while in qualitative studies feelings such as insecurity were described as influencing RTW. Conclusions Functional impairments can severely hamper work participation in breast cancer survivors. This provides important opportunities for occupational health professionals to enhance RTW in breast cancer survivors, such as adequately addressing illness perceptions and work expectations. Ongoing research is warranted to aid occupational health professionals in providing effective vocational guidance and improve work-related outcomes in breast cancer survivors.     

Meta-Synthesis of Qualitative Research on Facilitators and Barriers of Return to Work After Stroke

Purpose Despite existing rehabilitation services, return to work (RTW) rates among stroke survivors are quite low. An increased number of qualitative studies have been conducted to identify facilitators and barriers to RTW after stroke and to derive recommendations for future interventions. The aim of our study was to carry out a meta-synthesis of those studies and thus strengthen evidence in the field. Methods To identify relevant studies (qualitative studies focusing on RTW after stroke, published in English or German between 2000 and 2015), we conducted a systematic literature search in PubMed, OVID, and Web of Science. After assessing the quality of eligible studies, we synthesized their findings according to meta-ethnographic methodology. Results Fourteen out of 553 studies—three of very high, seven of high, three of medium, and one of low quality—met the inclusion criteria. After the extraction of all first-order concepts and their translation into 64 second-order interpretations, we synthesized the findings by developing a model of RTW factors after stroke. It contains factors related to the person (impairments, coping/adaptation, significance of work/RTW motivation), workplace (job demands/work adaptations, disability management, work climate/social support), and rehabilitation services (availability, accessibility, appropriateness), as well as relevant factors in the interaction of these three stakeholders (work capacity, performance and capability, and initial RTW experiences). Three basic principles—adaptiveness, purposefulness, and cooperativeness—complete the model and led us to its name: the APC model. Conclusions Successful RTW after stroke depends on diverse factors and stakeholders. Rehabilitation strategies have to consider this; otherwise they become RTW barriers themselves.     

The Effect of Self-Efficacy on Return-to-Work Outcomes for Workers with Psychological or Upper-Body Musculoskeletal Injuries: A Review of the Literature

Purpose Work absence can result in substantial losses to the economy and workers. As a result, identifying modifiable factors associated with return-to-work (RTW) following an injury or illness is the focus of many empirical investigations. Self-efficacy, the belief about one’s ability to undertake behaviours to achieve desired goals, has been identified as an important factor in RTW for injured workers. This paper systematically reviewed the literature on the association between self-efficacy and RTW outcomes for workers with an upper-body musculoskeletal injury or psychological injury. Methods A systematic search was conducted across five databases using two main search concepts- ‘self-efficacy’ and ‘RTW’. After removing duplicates, our search strategy identified 836 studies, which were screened for relevance using titles and abstracts. Results A two stage screening process reduced the study pool to six studies using psychological injury cohorts and three using upper-body musculoskeletal (UB-MSK) cohorts. Eight cohorts from seven prospective cohort studies and one sample from a randomised control trial (RCT) were subjected to a risk of bias assessment. Higher levels of self-efficacy appeared to have a consistent and positive association with RTW across return-to-work status and work absence outcomes, injury type and follow-up periods. Effect ratios ranged from 1.00 to 5.26 indicating a potentially large impact of self-efficacy on RTW outcomes. The relationship between self-efficacy and RTW strengthened as the domain of self-efficacy became more specific to RTW and job behaviours. Studies assessing workers with psychological injuries were of a lower quality compared to those assessing workers with UB-MSK injuries. Conclusions Higher self-efficacy had consistent positive associations with RTW outcomes. Further empirical research should identify the determinants of self-efficacy, and explore the processes by which higher self-efficacy improves RTW outcomes.     

Common Psychosocial Factors Predicting Return to Work After Common Mental Disorders,Cardiovascular Diseases,and Cancers: A Review of Reviews Supporting a Cross-Disease Approach

Purpose This systematic review aimed at identifying the common psychosocial factors that facilitate or hinder the return to work (RTW) after a sick leave due to common mental disorders (CMDs), cardiovascular diseases (CVDs), or cancers (CAs). Methods We conducted a review of reviews searching 13 databases from 1994 to 2016 for peer-reviewed, quantitative, cohort studies investigating factors influencing RTW after a CMD, CVD, or CA. Then, for each disease we identified additional cohort studies published after the date of the latest review included. Data were extracted following a three steps best-evidence synthesis method: the extraction of results about each predictor from studies within each single review and in the additional papers; the synthesis of results across the reviews and additional papers investigating the same disease; and the synthesis of results across the diseases. Results The search strategy identified 1029 unique records from which 27 reviews and 75 additional studies underwent comprehensive review. 14 reviews and 32 additional cohort studies met eligibility criteria. Specific predictors of RTW with different levels of evidence are provided for each disease. We found four common facilitators of RTW (job control, work ability, perceived good health and high socioeconomic status), and six barriers of RTW (job strain, anxiety, depression, comorbidity, older age and low education). Conclusion This is the first review to systematically analyze commonalities in RTW after CMDs, CVDs, or CAs. The common factors identified indicate that the RTW process presents many similarities across various diseases, thus supporting the validity of a cross-disease approach.     

Improving Return to Work Research

Background: Despite considerable multidisciplinary research on return to work (RTW), there has been only modest progress in implementation of study results, and little change in overall rates of work disability in developed countries. Methods: Thirty RTW researchers, representing over 20 institutions, assembled to review the current state of the art in RTW research, to identify promising areas for further development, and to provide direction for future investigations. Results and Conclusion: Six major themes were selected as priority areas: early risk prediction; psychosocial, behavioral and cognitive interventions; physical treatments; the challenge of implementing evidence in the workplace context; effective methods to engage multiple stakeholders; and identification of outcomes that are relevant to both RTW stakeholders and different phases of the RTW process. Understanding and preventing delayed RTW will require application of new concepts and study designs, better measures of determinants and outcomes, and more translational research. Greater stakeholder involvement and commitment, and methods to address the unique challenges of each situation are required.     

Bridging Health Care and the Workplace: Formulation of a Return-to-Work Intervention for Breast Cancer Patients Using an Intervention Mapping Approach

Purpose An increasing number of breast cancer (BC) survivors of working age require return to work (RTW) support. Objective of this paper is to describe the development of a RTW intervention to be embedded in the care process bridging the gap between hospital and workplace. Method The Intervention Mapping (IM) approach was used and combined formative research results regarding RTW in BC patients with published insights on occupational therapy (OT) and RTW. Four development steps were taken, starting from needs assessment to the development of intervention components and materials. Results A five-phased RTW intervention guided by a hospital-based occupational therapist is proposed: (1) assessing the worker, the usual work and contextual factors which impacts on (re-)employment; (2) exploration of match/differences between the worker and the usual work; (3) establishing long term goals, broken down into short term goals; (4) setting up tailored actions by carefully implementing results of preceding phases; (5) step by step, the program as described in phase 4 will be executed. The occupational therapist monitors, measures and reviews goals and program-steps in the intervention to secure the tailor-made approach of each program-step of the intervention. Conclusion The use of IM resulted in a RTW oriented OT intervention. This unique intervention succeeds in matching individual BC patient needs, the input of stakeholders at the hospital and the workplace.     

Participant Recruitment for Studies on Disability and Work: Challenges and Solutions

Purpose A number of key issues related to employment of persons with disabilities demand ongoing and effective lines of inquiry. There is evidence, however, that work researchers struggle with recruitment of participants, and that this may limit the types and appropriateness of methods selected. This two phase study sought to identify the nature of recruitment challenges in workplace-based disability research, and to identify strategies for addressing identified barriers. Methods The first phase of this study was a scoping review of the literature to identify the study designs and approaches frequently used in this field of inquiry, and the success of the various recruitment methods in use. In the second phase, we used qualitative methods to explore with employers and other stakeholders in the field their perceived challenges related to participating in disability-related research, and approaches that might address these. Results The most frequently used recruitment methods identified in the literature were non-probability approaches for qualitative studies, and sampling from existing worker databases for survey research. Struggles in participant recruitment were evidenced by the use of multiple recruitment strategies, and heavy reliance on convenience sampling. Employers cited a number of barriers to participation, including time pressures, fear of legal reprisal, and perceived lack of relevance to the organization. Conclusions Participant recruitment in disability-related research is a concern, particularly in studies that require collection of new data from organizations and individuals, and where large probability samples and/or stratified or purposeful samples are desirable. A number of strategies may contribute to improved success, including development of participatory research models that will enhance benefits and perceived benefits of workplace involvement.     

Determinants of Sickness Absence and Return to Work Among Employees with Common Mental Disorders: A Scoping Review

Purpose To present an overview of the existing evidence on prognostic factors of (recurrent) sickness absence (SA) and return to work (RTW) among workers with a common mental disorder (CMD). This scoping review provides information about determinants for SA and RTW, which could be used to develop better interventions aimed at the prevention of SA and promotion of RTW among workers with a CMD. Methods Relevant articles were identified in PubMed, Embase, PsycINFO, PSYNDEX, and SINGLE up to October 2016. In order to be included, studies should provide insight into prognostic factors of SA or RTW of workers with a CMD. We classified all factors according to the domains of the International Classification of Functioning, Disability and Health. Results Our searches identified 2447 possible relevant articles, of which 71 were included for data extraction. There is consistent evidence in ≥3 studies that previous episodes of CMD, higher symptom severity, previous absenteeism, co-morbidity, high job demands, low job control, high job strain, female gender, lower educational level, smoking behavior, and low perceived general health are predictors of SA in people with CMDs. Earlier RTW is consistently predicted by lower symptom severity, having no previous absenteeism, younger age, and positive expectations concerning sick-leave duration or RTW. Conclusions The amount of research on determinants for SA and RTW in workers with CMD has increased dramatically in recent years, although most studies are from the Netherlands and Scandinavia. There are some research gaps identified in this scoping review that need further attention in primary and secondary studies. Based on the summary of the evidence, we provide guidance for policy, practice and research.     

Subgroups of Long-Term Sick-Listed Based on Prognostic Return to Work Factors Across Diagnoses: A Cross-Sectional Latent Class Analysis

Comorbidity is common among long-term sick-listed and many prognostic factors for return to work (RTW) are shared across diagnoses. RTW interventions have small effects, possibly due to being averaged across heterogeneous samples. Identifying subgroups based on prognostic RTW factors independent of diagnoses might help stratify interventions. The aim of this study was to identify and describe subgroups of long-term sick-listed workers, independent of diagnoses, based on prognostic factors for RTW. Latent class analysis of 532 workers sick-listed for eight weeks was used to identify subgroups based on seven prognostic RTW factors (self-reported health, anxiety and depressive symptoms, pain, self-efficacy, work ability, RTW expectations) and four covariates (age, gender, education, physical work). Four classes were identified: Class 1 (45% of participants) was characterized by favorable scores on the prognostic factors; Class 2 (22%) by high anxiety and depressive symptoms, younger age and higher education; Class 3 (16%) by overall poor scores including high pain levels; Class 4 (17%) by physical work and lack of workplace adjustments. Class 2 included more individuals with a psychological diagnosis, while diagnoses were distributed more proportionate to the sample in the other classes. The identified classes illustrate common subgroups of RTW prognosis among long-term sick-listed individuals largely independent of diagnosis. These classes could in the future assist RTW services to provide appropriate type and extent of follow-up, however more research is needed to validate the class structure and examine how these classes predict outcomes and respond to interventions.

     

Guidelines for Vocational Evaluation Following Burns: Integrated Review of Relevant Process and Factors

Purpose A systematic literature review was undertaken to gather evidence to develop a guideline for vocational evaluation following burn injuries (BI). This review aimed to identify the key processes evaluators should follow and the key factors they should consider when completing such evaluations. Methods Steps outlined in Cochrane Handbook of Systematic Review were followed including: development of review question; search strategies and selection criteria; quality appraisal; data extraction; analysis & synthesis; drawing conclusions. Four databases (Pubmed, Medline, CINHAL, PsycINFO) and 14 websites were searched for relevant articles and studies (quantitative, qualitative), reviews and guidelines. Two reviewers independently completed reviews, performed quality assessments and extracted data into evidence tables. Using the ICF model and directed content analysis, key processes and factors were analyzed and synthesized across the evidence. Results A total of 138 articles were identified using the key words (e.g. burns, work). Studies, reviews and guidelines were retrieved if they focused on adults and discussed the processes relevant to vocational evaluation and/or factors associated with successful return to work (RTW) following a BI. Items were excluded if they did not address adults who had suffered a burn, the process of work or RTW, or challenges related to work after a BI. Using the above criteria 76 items were retrieved for full review. Fifty-six items remained after the quality appraisal. Results were integrated to develop the Evidence-based Framework for Vocational Evaluation Following Burn Injury. Conclusions This framework outlines 7 key processes relevant to vocational evaluation following burn injuries.
