Experiences of workers with long-term disabilities on employer support throughout the RTW process in The Netherlands: a qualitative study

PURPOSE

The aim of this qualitative study was to explore ways that employer support influenced successful return to work (RTW) in workers with disabilities.

METHODS

We conducted a semi-structured interview study among 27 workers with disabilities in the Netherlands who received a partial disability benefit two years after sick leave and who continued working in paid (part-time) employment after a period of long-term sickness absence (> 2 years). We analyzed data by means of thematic analysis.

RESULTS

We identified four types of employer support that were experienced as factors of successful RTW: 1. Supervisor accessibility; 2. Supervisor engagement; 3. Supervisor strategies; and 4. Supervisor-initiated work accommodations. More specifically, during the preparations for RTW phase, the supervisor's active role involved having a positive and open attitude toward facilitating RTW; during the initial RTW phase, the supervisor's role involved being creative in finding solutions for work accommodations; and during the sustained RTW phase, the supervisor's role included helping workers who still needed changes in their work situations.

CONCLUSION

The elements of successful employer support reveals that the pressure on the shoulders of the supervisor is high. Future research should further investigate whether supervisors need more phase-specific training from their organization.

Diverging death risks: Mortality as a corollary of economic, social, cultural and person capital

Introduction

Diverging death risks are associated with a wide range of social factors, including not only education and income but also other economic and non-economic resources. The aim of this study was to assess the association of mortality risks with four types of resources: economic, social, cultural and person capital.

Methods

We used data of 2,952 participants from the Disparities in the Netherlands survey and annual mortality data from Statistics Netherlands for the period 2014 to 2021. Economic capital was measured through education, income, occupation, home equity, and liquid assets. Social capital was measured by the strength of social ties, the size of the core discussion network, and access to people in resourceful positions; cultural capital by lifestyle, digital skills, and mastery of English, and person capital by self-rated health, impediments to climbing stairs, self-confidence, self-image, people's appearance, and body mass index. To accommodate the fact that each capital was derived from several indicators, we used Partial Least Squares (PLS) Cox Regression.

Results

In multiple regression, higher economic, cultural, and person capital were associated with lower mortality (hazard ratio, 0.77; 95% confidence interval [CI, 0.65 to 0.90], 0.77 [0.64-0.93] and 0.80; [0.70-0.92]), adjusted for all capital measures and sex.

Conclusion

The finding that more economic, cultural and person capital is associated with lower mortality provides empirical support for an approach that uses a broad spectrum of capital measures - hitherto rarely included simultaneously in epidemiological research - in order to understand diverging death risks. By integrating sociological concepts, cohort data, and epidemiological research methods, our study highlights the need for further research on the interplay between different forms of resources in shaping health inequalities. In designing public health interventions, we advocate the adoption of a multidimensional capital-based framework for tackling social disparities in mortality.

Return to work policies and practices after total hip or knee arthroplasty in Denmark, Germany, and the Netherlands: an exploratory study

PURPOSE

To explore return-to-work (RTW) policies and practices for total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients in three European countries.

MATERIALS AND METHODS

An exploratory study in Denmark, Germany, and the Netherlands consisting of three aspects: (1) description of the healthcare and social security systems; (2) identification of national RTW guidelines; (3) a survey to gain insight into RTW practices and perceptions of orthopaedic surgeons, including barriers, facilitators, and needs.

RESULTS

Healthcare and social security systems differed (e.g. fast-track vs longer postoperative stay; coverage of rehabilitation costs). National guidelines were available in Germany (THA, TKA) and the Netherlands (TKA), containing limited RTW information. The survey was completed by 168 orthopaedic surgeons (Denmark n = 51; Germany n = 39; the Netherlands n = 78). Overall, orthopaedic surgeons reported being in need of more knowledge and better collaboration with other healthcare practitioners.

CONCLUSION

We found considerable variation in healthcare and social security systems. When available, national guidelines contained limited information. In all three countries surgeons need more knowledge and better collaboration with other healthcare practitioners. We advise that RTW multidisciplinary recommendations post THA/TKA be established by the national associations of the healthcare practitioners involved.

Three out of four working-age patients have fulfilled expectations towards paid employment six months after total hip or knee arthroplasty: a multicentre cohort study

To investigate factors associated with fulfilment of expectations towards paid employment after total hip/knee arthroplasty (THA/TKA). Cohort study including preoperatively employed patients aged 18-64 scheduled for THA/TKA. Expectations were collected preoperatively, and 6 and 12 months postoperatively with the paid employment item of the Hospital-for-Special-Surgery Expectations Surveys (back-to-normal = 1; large improvement = 2; moderate improvement = 3; slight improvement = 4; not applicable = 5). Patients scoring not applicable were excluded. Fulfilment was calculated by subtracting preoperative from postoperative scores (< 0: unfulfilled; ≥ 0: fulfilled). Multivariable logistic regression analyses were conducted separately for THA/TKA at 6 and 12 months postoperatively. Six months postoperatively, 75% of THA patients (n = 237/n = 316) and 72% of TKA patients (n = 211/n = 294) had fulfilled expectations. Older age (TKA:OR 1.08, 95% CI 1.01-1.15) and better postoperative physical functioning (THA:OR 1.10, 95% CI 1.06-1.14; TKA:OR 1.03, 95% CI 1.01-1.06) increased the likelihood of fulfilment. Physical work tasks (THA:OR 0.12, 95% CI 0.03-0.44), preoperative sick leave (TKA:OR 0.33, 95% CI 0.17-0.65), and difficulties at work (THA:OR 0.10, 95% CI 0.03-0.35; TKA:OR 0.41, 95% CI 0.17-0.98) decreased the likelihood of fulfilment. Twelve months postoperatively similar risk factors were found. Three out of four working-age THA/TKA patients had fulfilled expectations towards paid employment at 6 months postoperatively. Preoperative factors associated with fulfilment were older age, mental work tasks, no sick leave, postoperative factors were better physical functioning, and no perceived difficulties at work.

Symptom profiles and their risk factors in patients with post-COVID-19 condition: a Dutch longitudinal cohort study

BACKGROUND

To improve research and care for patients with post-COVID-19 condition more insight into different subtypes of post-COVID-19 condition and their risk factors is urgently needed. We aimed to identify risk factors of post-COVID-19 condition in general and for specific symptom profiles.

METHODS

This study is based on data collected within the Lifelines Coronavirus disease 2019 (COVID-19) cohort (N = 76 503). Mean pre- and post-SARS-CoV-2 infection symptom scores were compared to classify post-COVID-19 condition. Latent Profile Analysis was used to identify symptom profiles. Logistic and multinomial regression analyses were used to examine the association between demographic, lifestyle and health-related risk factors and post-COVID-19 condition, and symptom profiles, respectively.

RESULTS

Of the 3465 participants having had COVID-19, 18.5% (n = 642) classified for post-COVID-19 condition. Four symptom profiles were identified: muscle pain, fatigue, cardiorespiratory and ageusia/anosmia. Female sex was a risk factor for the muscle pain and fatigue profiles. Being overweight or obese increased risk for all profiles, except the fatigue profile. Having a chronic disease increased the risk for all profiles except the ageusia/anosmia profile, with the cardiorespiratory profile being only significant in case of multimorbidity. Being unvaccinated increased risk of the ageusia/anosmia profile.

CONCLUSIONS

Findings from this study suggest that Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may trigger different pathophysiological mechanisms that may result in different subtypes of post-COVID-19 condition. These subtypes have shared and unique risk factors. Further characterization of symptom profiles and quantification of the individual and societal impact of specific symptom profiles are pressing challenges for future research.

Residual Work Capacity and (In)Ability to Work Fulltime Among a Year-Cohort of Disability Benefit Applicants Diagnosed with Mental and Behavioural Disorders

AIMS

Residual work capacity and inability to work fulltime are important outcomes in disability benefit assessment for workers with mental and behavioural disorders. The aim of this study is to gain insight into the prevalence and associations of socio-demographic and disease-related factors of these outcomes across different mental and behavioural diagnoses groups.

METHODS

A year cohort of anonymized register-data of patients diagnosed with a mental or behavioural disorder who claim a work disability benefit after two years of sick-leave was used (n = 12,325, age 44.5 ± 10.9, 55.5% female). Limitations in mental and physical functioning caused by disease are indicated according to the Functional Ability List (FAL). No residual work capacity was defined as having no possibilities to work, whereas inability to work fulltime was defined as being able to work less than 8 h per day.

RESULTS

The majority (77.5%) of the applicants were assessed with residual work capacity, of these 58.6% had an ability to work fulltime. Applicants diagnosed with (post-traumatic) stress, mood affective and delusional disorders showed significant higher odds for no residual work capacity and for inability to work fulltime, while other diagnoses groups, like adjustment and anxiety disorders, showed decreased odds for both assessment outcomes.

CONCLUSIONS

The type of mental and behavioural disorder seems important in the assessment of residual work capacity and inability to work fulltime, as the associations differ significantly between the specific diagnoses groups.

Process evaluation of a comprehensive approach to reintegration of disability benefit recipients with multiple problems (CARm) into the labour market

PURPOSE

As the effect evaluation of our randomized controlled trial the "Comprehensive Approach of Reintegration for clients with Multiple problems" (CARm) showed no superior effect on re-integration into paid employment of the clients when compared with clients of the care as usual, we conducted this process evaluation to gain insight into whether the intervention was conducted according to protocol.

METHODS

Using questionnaires on recruitment, reach, dose delivered, dose received, fidelity, context, and satisfaction we collected data from 40 labour experts of the Public Employment Service of the Dutch Social Security Institute, and from 166 disability benefit recipients dealing with multiple problems.

RESULTS

Only few of the labour experts provided the key elements of the intervention to their clients. Between the clients of both groups were no significant differences in the dose received. More than half of the labour experts of the intervention group reported organizational changes.

CONCLUSION

The lack of effect of the CARm intervention was almost certainly caused by implementation failure. Once again this study showed the importance of involving all stakeholders in developing and the conduct of the intervention, and of clarifying the consequences for the organization, to ensure that it can be conducted according to protocol.

Time to return to work by occupational class after total hip or knee arthroplasty

Aims

For the increasing number of working-age patients undergoing total hip or total knee arthroplasty (THA/TKA), return to work (RTW) after surgery is crucial. We investigated the association between occupational class and time to RTW after THA or TKA.

Methods

Data from the prospective multicentre Longitudinal Leiden Orthopaedics Outcomes of Osteoarthritis Study were used. Questionnaires were completed preoperatively and six and 12 months postoperatively. Time to RTW was defined as days from surgery until RTW (full or partial). Occupational class was preoperatively assessed and categorized into four categories according to the International Standard Classification of Occupations 2008 (blue-/white-collar, high-/low-skilled). Cox regression analyses were conducted separately for THA and TKA patients. Low-skilled blue-collar work was used as the reference category.

Results

A total of 360 THA and 276 TKA patients, preoperatively employed, were included. Patients were mainly high-skilled (THA 57%; TKA 41%) or low-skilled (THA 24%; TKA 38%) white-collar workers. Six months post-THA, RTW rates were 78% of low-skilled blue-collar workers compared to 83% to 86% within other occupational classes, increasing after 12 months to 87% to 90% in all occupational classes. Six months post-TKA, RTW rates were 58% of low-skilled and 64% of high-skilled blue-collar workers compared to 80% to 89% of white-collar workers, and after 12 months 79% of low-skilled blue-collar workers compared to 87% to 92% within other occupational classes. High-skilled white-collar workers (THA: hazard ratio (HR) 2.12 (95% confidence interval (CI) 1.32 to 3.40); TKA: HR 2.31 (95% CI 1.34 to 4.00)) and low-skilled white-collar workers (TKA: HR 1.82 (95% CI 1.04 to 3.18)) had a higher hazard to RTW within six months postoperatively.

Conclusion

Clear differences existed in time to RTW among both THA and TKA patients in each of the groups studied. These findings may help guide tailored patient-specific information during preoperative consultation and advice postoperatively, as well as to create awareness among workers and their employers.

Sustained employment, work disability and work functioning in CKD patients: a cross-sectional survey study

INTRODUCTION

Kidney failure negatively affects opportunities for work participation. Little is known about work functioning of employed CKD patients. This study investigates work-related outcomes, and examines associations between patient characteristics and employment status.

METHODS

We performed a cross-sectional survey study in nine nephrology outpatient clinics in the Netherlands among working age (18-67 years) CKD Stage G3b-G5, dialysis and transplant patients (n = 634; mean age 53.4 years (SD 10); 53% male; 47% Stage G3b-G5, 9% dialysis, 44% transplantation). We assessed employment status, work disability, work-related characteristics (i.e., work situation, working hours, job demands), work functioning (i.e., perceived ability to work, productivity loss, limitations in work), work environment (i.e., work accommodations, psychosocial work environment), as well as health status and fatigue.

RESULTS

Sixty-five percent were employed reporting moderate work ability. Of those, 21% received supplementary work disability benefits, 37% were severely fatigued, 7% expected to drop out of the workforce, and 49% experienced CKD-related work limitations. Work accommodations included reduced working hours, working at a slower pace, adjustment of work tasks or work schedule, and working from home. Multivariable analysis of sustained employment showed associations with younger age, male gender, higher level of education, better general and physical health and pre-emptive transplantation. Transplant patients had the highest work ability and highest expectation to maintain work. Dialysis patients had the highest productivity loss and perceived the most limitations regarding functioning in work. Stage G3b-G5 patients reported the lowest social support from colleagues and highest conflict in work and private life.

CONCLUSIONS

Employed CKD patients experience difficulties regarding functioning in work requiring adjustment of work or partial work disability. In addition to dialysis patients, stage G3b-G5 patients are vulnerable concerning sustained employment and work functioning.

Development and implementation of work-oriented clinical care to empower patients with kidney disease: an adapted intervention mapping approach

BACKGROUND

Many people with chronic kidney disease (CKD) have problems to stay at work. Patients and health care professionals (HCPs) see the potential benefit of work-oriented clinical care, yet this care is not manifested in current practice. The aim of this study was to develop and implement a program called work-oriented clinical care for kidney patients (WORK) to support sustainable work participation.

METHODS

An adapted version of Intervention Mapping (AIM) was used for the systematic development of work-oriented care in a hospital. Based on the needs of patients and (occupational) health professionals, and in close cooperation with both, a theoretical and empirically based program was developed. Feasibility and clinical utility were assessed among patients with CKD, HCPs and hospital managers. To increase the chances of successful implementation we focused on determinants related to the innovation, the users, the organization (hospital), and socio-political context.

RESULTS

We developed, implemented, and pilot-tested WORK, an innovative program consisting of a care pathway in the hospital that targets patients with work-related questions and tailors the support they receive to their needs. Several practical tools were developed and an internal and external referral structure with a focus on work was implemented. A labor expert was deployed to the hospital to support patients and HCPs with simple work-related questions. The feasibility and clinical utility of WORK were rated positively.

CONCLUSIONS

This work-oriented clinical care program provides HCPs in the hospital with the necessary tools to support patients with CKD in dealing with work challenges. HCPs can discuss work with patients at an early stage and support them in anticipating work-related challenges. HCPs can also bridge the gap to more specialized help if necessary. WORK has the potential for wider application in other departments and hospitals. So far, the implementation of the WORK program was successful, though structural implementation may be challenging.

Discrepancies between workers with disabilities and their supervisors in reported work accommodations and associations with return to work

BACKGROUND

The aims of this study were: (1) to explore the frequency of discrepancies in work accommodations reported by workers and their supervisors, and (2) to investigate whether these discrepancies are associated with full return to work (RTW).

METHODS

We used data from a longitudinal survey study of long-term sick-listed workers and their supervisors (n = 406). Discrepancies in reports on implementing eight types of work accommodations were explored. Logistic regression analyses were conducted to test associations between discrepancies in reported work accommodations and odds of full RTW 27 months after the sick-leave onset.

RESULTS

Discrepancies were the lowest for the work accommodation therapeutic RTW (53%) and the highest (85%) for job training or education and reimbursement of therapy or treatment. Four out of eight types of work accommodations were more often reported by workers than by their supervisors. Only a discrepancy on a job reassignment within the organization was associated with lower odds of full RTW (OR 0.56, 95%-CI 0.36-0.88).

CONCLUSION

We found substantial discrepancies in the reported implementation of work accommodations between workers and their supervisors. Future research should focus on disentangling mechanisms that lead to discrepancies to avoid inefficiencies in the RTW process.

Do influence at work and possibilities for development mitigate the impact of job demands for workers with and without depression

OBJECTIVE

Jobs characterized by low job demands and high job resources are associated with better work outcomes, yet it remains unclear whether this is the case for workers with depression. This study examined whether depression moderates the relationship between job demands, job resources, and maintaining employment.

METHODS

Data from the longitudinal population-based Lifelines cohort study were matched with register data on employment from Statistics Netherlands (N=55 950). Job demands included quantitative demands and work pace; job resources included influence at work and possibilities for development. The two-way interaction between job demands and depression and the three-way interaction between job demands, job resources and depression were examined in a zero-inflated Poisson regression model with path 1, including a binary employment outcome, and path 2, a count variable including months out of employment.

RESULTS

The interaction effect of job demands and depression on being employed was significant [b=-0.22, 95% confidence interval (CI) -0.44‒0.01]. Workers without depression were more likely to be employed whereas workers with depression were less likely to be employed if they had high job demands. The three-way interaction between job demands, job resources, and depression was significant for months out of employment (b=0.15, 95% CI 0.01‒0.29), indicating that workers with depression had more months out of employment when reporting high job demands and high job resources compared to workers without depression. Discussion Although increasing influence at work and possibilities for development to prevent negative work outcomes may be beneficial for workers without depression, this approach might be limited for workers with depression.

The Associations Between Illness Perceptions and Expectations About Return to Work of Workers With Chronic Diseases and Their Significant Others: A Dyadic Analysis

Purpose To examine the associations between illness perceptions and expectations about full return to work (RTW) of workers with chronic diseases and their significant others. Methods This study used cross-sectional data of 94 dyads consisting of workers with chronic diseases and their significant others. We performed dyadic analyses based on the Actor-Partner Interdependence Model (APIM), estimating associations of illness perceptions of the two members of the dyad with their own expectations about the worker's full RTW within six months (actor effect) as well as with the other dyad member's expectations about the worker's RTW (partner effect). Results Illness perceptions of one dyad member were significantly associated with his or her own RTW expectations (actor effect composite illness perceptions score; B = -0.05, p < .001; r_d = .37) and with the other dyad member's RTW expectations (partner effect composite illness perceptions score; B = -0.04, p < .001; r_d = .35). That is, more negative illness perceptions of one member of the dyad were associated with more negative RTW expectations in both dyad members. For most illness perception domains, we found small to moderate actor and partner effects on RTW expectations (r_d range: .23-.44). Conclusions This study suggests that illness perceptions and RTW expectations should be considered at a dyadic level as workers and their significant others influence each other's beliefs. When trying to facilitate adaptive illness perceptions and RTW expectations, involving significant others may be more effective than an individualistic approach targeted at the worker only.

A capital-based approach to better understand health inequalities: Theoretical and empirical explorations

Background

The persistence of health inequalities may be driven by differences in education and income, but also by other economic and non-economic factors. Our aim was to explore how the association between single-dimensional health and socioeconomic status (SES) changes when including health-related person capital, economic capital, social capital, cultural capital and attractiveness and personality capital.

Methods

We used a capital-based approach to understand health inequalities. It presumes intertwined relationships between broadly measured health ('health-related person capital') and embodied resources ('attractiveness and personality capital') on the one hand, and ESC capital, i.e., economic, social, and cultural resources on the other. We used cross-sectional data on 152,592 participants from the Dutch Lifelines cohort study and estimated correlations using partial least squares structural equation modelling.

Results

The correlation between SES and health-related person capital (r = 0.15) was stronger than the correlations between SES and single-dimensional health (physical and mental health; r = 0.12 and r = 0.04, respectively). ESC capital, combining economic, social and cultural capital, showed a correlation of 0.34 with health-related person capital. This was stronger than the correlation between health-related person capital and economic capital alone (r = 0.19). Lastly, the correlation between health-related person capital and ESC capital increased when health related, attractiveness and personality resources were combined into a single person capital construct (from r = 0.34 to r = 0.49).

Conclusions

This exploratory study shows the empirical interconnectedness of various types of resources, and their potential role in the persistence of health inequalities. Our findings corroborate the idea of considering health as a multidimensional concept, and to extend conventional SES indicators to a broader measurement of economic and non-economic resources.

Workers' views on involving significant others in occupational health care: a focus group study among workers with a chronic disease

PURPOSE

To explore workers' views and considerations on involving their significant others (SOs) in occupational health care.

METHODS

Four focus group interviews in the Netherlands, with 21 workers who had visited an occupational health physician (OHP) due to work absence caused by a chronic disease. Data was analyzed using thematic analysis.

RESULTS

We distinguished four main themes: (i) attitudes towards involving SOs, (ii) preferences on how to involve SOs, (iii) benefits of involving SOs, and (iv) concerns with regard to involving SOs. Workers expressed both positive and critical opinions about involving SOs in occupational health care. Benefits mentioned included provision of emotional and informational support by SOs before, during, and after consultations. According to workers, support from SOs can be enhanced by informing SOs about re-integration plans and involving them in decision making. However, workers were concerned about overburdening SOs, and receiving unwanted support from them.

CONCLUSIONS

According to interviewed workers, engagement of SOs in occupational health care can help workers with a chronic disease in their recovery and return to work. However, they felt it is important to take SO characteristics and the worker's circumstances and preferences into account, and to balance the potential benefits and drawbacks of involving SOs.Implications for rehabilitationThis study suggests that the worker's re-integration process could benefit from informing significant others about the return to work plans, involving them in decision-making, and explicitly discussing how the significant other can support the worker.Occupational health physicians have an important role in informing workers about the possibility and potential benefits of involving their significant others in the re-integration process.The involvement of a significant other in the re-integration process needs to be tailored to the specific situation of the individual worker, taking into account the preferences of both the worker and significant other.Findings suggest that it is important that occupational health physicians, workers and significant others are not only aware of the possible benefits of significant other involvement, but also of potential drawbacks such as interference during consultations, overburdening significant others, and significant others providing unwanted support.

A capital-based approach to understand health inequalities: empirical explorations

Background

The persistence of health inequalities may not be merely driven by education and income, but also by other economic and non-economic factors. In this study we investigated how the association between single-dimensional health and socioeconomic status (SES) changes when including health-related person capital, economic capital, social capital, cultural capital and non-health related person capital.

Methods

The present study proposes a capital-based approach to understand health inequalities. It presumes intertwined relationships between a wide notion of health (‘health-related person capital’) and embodied resources (‘non-health related person capital’) on the one hand, and non-person capital, i.e. economic, social, and cultural resources on the other. We used cross-sectional data on 152,592 participants from the Dutch Lifelines cohort study. Correlations between capital constructs were estimated using partial least squares structural equation modelling.

Results

The correlation between health-related person capital and SES (r = 0.15) was higher than the correlations between single-dimensional health (physical and mental health) and SES (r = 0.12, r = 0.04, respectively). Non-person capital, combining economic, social and cultural capital, showed a correlation of 0.34 with health-related person capital. This was higher than the correlation between health-related person capital and economic capital alone (r = 0.19). Lastly, the correlation between health-related person capital and non-person capital increased when non-health (personality and attractiveness) and health related person capital were combined into person capital construct (from r = 0.34 to r = 0.49).

Conclusions

This exploratory observational study shows the empirical interconnectedness of various types of resources. Our findings corroborate the idea of considering health as a multidimensional concept, and to extend conventional SES indicators to a broader measurement of economic and non-economic resources.

Key messages

Job resources do not mitigate the impact of job demands for workers with depression

Introduction

Jobs characterized by low to moderate job demands and high job resources are associated with better work outcomes among healthy workers, yet it remains unclear whether this is the case for workers with depression. This study examined whether depression moderates the relationship between job demands, job resources, and maintaining employment.

Methods

Data from the longitudinal population-based Lifelines cohort study were matched with register data on employment status from Statistics Netherlands (n = 55,950). The two-way interaction between job demands and depression and the three-way interaction between job demands, job resources and depression were examined in a zero-inflated Poisson regression model with path 1 including a binary employment outcome and path 2 a count variable including months out of employment.

Results

The interaction effect of job demands and depression on being employed was significant (b=-0.22, 95% CI: -0.44; 0.01), showing that workers without depression were more likely to be employed whereas workers with depression were less likely to be employed if they had high job demands. The three-way interaction between job demands, job resources, and depression was significant for months out of employment (b = 0.15, 95% CI: 0.01; 0.29), indicating that workers with depression had more months out of employment when reporting high job demands and high job resources compared to workers without depression.

Discussion

Although increasing resources to prevent negative work outcomes may be beneficial for workers without depression, this approach might be limited for the vulnerable subgroup of workers with depression.

Associations between perceptions and sick leave duration in dyads of workers and significant others

Background

Dyadic processes of workers and significant others like partners, family members and friends can play an important role in adaptation to chronic disease, thereby influencing health and work outcomes. This study aimed to increase our understanding of dyadic processes in sick leave duration of workers with chronic diseases. We examined illness perceptions, return to work expectations (RTWE) and perceptions about significant other responses (i.e., engagement, buffering and overprotection) of workers and their significant others in relation to sick leave duration.

Methods

This study used survey and registry data of 90 dyads of sick-listed workers with a chronic disease and their significant others. Simple and multiple regressions in which perceptions of workers and significant others were included simultaneously were used to examine associations with sick leave duration.

Results

Workers’ and significant others’ perceptions were moderately to strongly correlated (r ranged from .46 to .80). Sick leave duration was associated with illness perceptions of both workers (b = 8.58, p=.001) and significant others (b = 6.46, p=.008), with more negative illness perceptions associated with a longer sickness absence. In the multiple regression, illness perceptions explained 12.3% of the variation in sick leave duration. Sick leave duration was also associated with RTWE of workers (b=-76.87, p&lt;.001) and their significant others (b=-92.47, p&lt;.001), with more positive RTWE associated with a shorter sickness absence. The RTWE of dyad members accounted for 24.5% of the variance of sick leave duration.

Conclusions

Illness perceptions and RTWE of workers and their significant others are strongly interdependent and associated with sick leave duration of workers with chronic diseases. A dyadic approach targeted at improving illness perceptions and RTWE of both workers and significant others might be more effective than an individualistic approach in preventing long-term sickness absence.

Key messages

• Return to work expectations and illness perceptions of workers and their significant others are associated with the duration of sickness absence of workers with chronic diseases.

• A dyadic approach targeted at both workers and their significant others might be more effective than an individualistic approach in the prevention of long-term sickness absence.

Evaluation of an e-learning on involving significant others in occupational health care

Background

Significant others (SOs) like partners, family members or friends can play an important role in how workers cope with chronic disease, thereby influencing work and health outcomes. Despite the potential benefits of involving SOs in the return-to-work (RTW) process of workers with chronic diseases, guidance and training on how to manage this is scarce. Educating work and health professionals on this topic could lead to better RTW support for workers and prevention of long-term sickness absence.

Objectives

This study aimed to determine the effectiveness of an e-learning for improving occupational health physicians’ (OHPs) knowledge, attitudes, and self-efficacy regarding involving SOs in the RTW process. In addition, we explored OHPs’ responses to and satisfaction with the e-learning. We conducted a randomized controlled trial with 87 OHPs, involving an intervention group and a waitlisted control group. Between-group differences in knowledge, attitude, self-efficacy outcomes, and retention of effects were assessed using ANOVA and paired t-tests. Reactions to the e-learning were analyzed with descriptive statistics and thematic analysis.

Results

We found moderate to large effects on OHPs’ knowledge (p &lt;.001, ηp2 = .202), attitudes (ηp2 = .098), and self-efficacy (p &lt; .001, ηp2 = .237), with retention of all changes at 10-week follow-up. OHPs graded the e-learning with a mean score of 7.9 out of 10 (SD = 1.11) and indicated that the e-learning increased their awareness of the role of SOs in RTW and encouraged them to address this more often.

Conclusions

The developed e-learning is the first evidence-based training to improve the knowledge, attitudes, and self-efficacy of OHPs with regard to involving SOs in the RTW process of workers with chronic diseases. The e-learning and accompanying materials can encourage work and health professionals to more often address the role of significant others in the work re-integration process.

Key messages

• The developed e-learning is effective in increasing occupational health physicians’ knowledge, attitudes and self-efficacy with regard to involving significant others in the return-to-work process.

• The e-learning and accompanying materials can encourage professionals to more often address the role of significant others in the work re-integration process to prevent long-term sickness absence.

Increases in symptoms of depression and anxiety in adults during the initial phases of the COVID-19 pandemic are limited to those with less resources: Results from the Lifelines Cohort Study

BACKGROUND

The COVID-19 pandemic may have a differential impact on mental health based on an individual's capital, i.e. resources available to maintain and enhance health. We assessed trajectories of depression and anxiety symptoms, and their association with different elements of capital.

METHODS

Data on 65,854 individuals (mean baseline age = 50·4 (SD = 12·0) years) from the Lifelines COVID-19 cohort were used. Baseline mental health symptoms were on average measured 4.7 (SD = 1·1) years before the first COVID-19 measurement wave, and subsequent waves were (bi)weekly (March 30─August 05, 2020). Mental health symptom trajectories were estimated using a two-part Latent Class Growth Analysis. Class membership was predicted by economic (education, income, and occupation) and person capital (neuroticism, poor health condition, and obesity) FINDINGS: Most individuals were unlikely to report symptoms of depression (80·6%) or anxiety (75·9%), but stable-high classes were identified for both conditions (1·6% and 6·7%, respectively). The stable-high depression class saw the greatest increase in symptoms after COVID, and the stable-high anxiety class reported an increase in the probability of reporting symptoms after COVID. At the first COVID-measurement, the mean number of symptoms increased compared to baseline (depression:4·7 vs 4·1; anxiety:4·3 vs 4·2); the probability of reporting symptoms also increased (depression:0·96 vs 0·65; anxiety:0·92 vs 0·70). Membership in these classes was generally predicted by less capital, especially person capital; odds ratios for person capital ranged from 1·10-2·22 for depression and 1·08-1·51 for anxiety.

INTERPRETATION

A minority of individuals, possessing less capital, reported an increase in symptoms of depression or anxiety after COVID.

Social Insurance Literacy of Dutch Workers Receiving Disability Benefits and its Associations with Socio-Economic Characteristics

Purpose This study explores the concept social insurance literacy (SIL) and corresponding questionnaire (SILQ) among workers receiving disability benefits and the comprehensibility of the social security institute (SSI), and examines associations with socio-economic characteristics. Methods 1753 panel members of the Dutch SSI were approached to complete the SILQ-NL37. This measure was based on the original SILQ. The SILQ-NL37 contains domains for obtaining, understanding and acting upon information for both individual SIL and system comprehensibility. A higher score means better SIL or comprehensibility. Data on age, gender, education, living situation, Dutch skills and time receiving disability benefits were also collected. With k-means clustering, groups with adequate and limited SIL were created. Associations with socio-economic characteristics were examined with independent t-tests and linear regression analyses for both the total scores and within domain scores. Cronbach α and Spearman rho's indicated measurement properties were good to acceptable for the SILQ-NL37. Results Thirty-five percent of the 567 participants were in the group with limited SIL. Higher individual SILQ-NL37 scores were associated with having a partner (p = 0.018) and northeastern living region (p = 0.031). Higher scores for obtaining (p = 0.041) and understanding (p = 0.049) information were associated with female sex, and for acting on information with younger age (p = 0.020). People with limited Dutch skills (p = 0.063) and a partner (p = 0.085) rated system comprehensibility higher. Conclusions According to the SILQ-NL37 scores, about 35% of the panel members have limited ability to obtain, understand and act upon social insurance systems information. Limited SIL is associated with several socio-economic factors. Future researches should study the concept in a more representative sample, and in different countries and social insurance contexts.

Employment and ability to work after kidney transplantation in the Netherlands: The impact of preemptive versus non-preemptive kidney transplantation

BACKGROUND

Work can have a major positive impact on health and wellbeing. Employment of kidney transplant recipients (KTR) of working age is much lower than in the general population. The first aim of this study was to examine the impact of a preemptive kidney transplantation (PKT) on employment, in addition to other possible influencing factors. The second aim was to explore differences in work ability, absenteeism and work performance among employed KTR with different types of transplantations.

METHODS

A cross-sectional survey study was conducted between 2018 and 2019 in nine Dutch hospitals. PKT as potential predictor of employment was examined. Furthermore, work ability, absenteeism and loss of work performance were compared between employed preemptive recipients with a living donor (L-PKT) and non-preemptive recipients with a living donor (L-nPKT) and with a deceased donor (D-nPKT).

RESULTS

Two hundred and twenty four KTR participated; 71% reported having paid work. Paid work was more common among PKT recipients (82% vs. 65% in L-nPKT and 55% in D-nPKT) and recipients who were younger (OR .950, 95%CI .913-.989), had no comorbidities (1 comorbidity: OR .397, 95%CI .167-.942; 2 comorbidities: OR .347, 95%CI .142-.844), had less fatigue (OR .974, 95%CI .962-.987) and had mentally demanding work tasks (only in comparison with physically demanding tasks, OR .342, 95%CI .145-.806). If recipients were employed, D-nPKT recipients worked fewer hours (mean 24.6±11.3 vs. PKT 31.1±9.6, L-nPKT 30.1±9.5) and D-nPKT and L-nPKT recipients received more often supplemental disability benefits (32 and 33.3%, respectively) compared to PKT recipients (9.9%). No differences were found for self-reported ability to work, sick leave (absenteeism) and loss of work performance with the exception of limitations in functioning at work.

CONCLUSIONS

Preemptive kidney transplantation recipients with a kidney from a living donor are employed more often, work more hours per week (only in comparison with D-nPKT) and have a partial disability benefit less often than nPKT recipients. More knowledge regarding treatments supporting sustainable participation in the labor force is needed as work has a positive impact on recipients' health and wellbeing and is also beneficial for society as a whole.

Training for occupational health physicians to involve significant others in the return-to-work process of workers with chronic diseases: a randomized controlled trial

PURPOSE

To determine the efficacy of the "Training for Occupational health physicians To Involve Significant others" (TOTIS) e-learning module for improving occupational health physicians' (OHPs) knowledge, attitudes, and self-efficacy regarding involving significant others in the return-to-work process.

MATERIALS AND METHODS

A randomized controlled trial with 87 OHPs, involving an intervention group and a wait-listed control group. Between-group differences in knowledge, attitude, and self-efficacy outcomes, and retention of effects were assessed using ANOVA and paired t-tests. Reactions to the e-learning module were analyzed with descriptive statistics and thematic analysis.

RESULTS

We found moderate to large effects on OHPs' knowledge (p < 0.001, η_p² = 0.202), attitudes (p = 0.003, η_p² = 0.098), and self-efficacy (p < 0.001, η_p² = 0.237), with retention of all changes at 10-week follow-up. OHPs graded the e-learning module with a mean score of 7.9 out of 10 (SD = 1.11) and indicated that the module increased their awareness of the role of significant others and encouraged them to address this more often.

CONCLUSIONS

The TOTIS e-learning module and accompanying materials are valuable resources for OHPs to learn how significant others influence work outcomes of workers with chronic diseases and to manage their involvement in the re-integration process.

TRIAL REGISTRATION

This study is registered in the Netherlands Trial Register under trial number NL8744; https://www.trialregister.nl/trial/8744.Implications for rehabilitationThe TOTIS e-learning module is the first evidence-based training to improve the knowledge, attitudes, and self-efficacy of occupational health physicians with regard to involving significant others in the re-integration process of workers with chronic diseases.The e-learning module and accompanying tools can increase the awareness of occupational health physicians about the role of significant others and encourage them to address the role of significant others in the re-integration process of sick-listed workers.It could be beneficial to expand on the e-learning module with a face-to-face training program involving group interaction, peer discussion, and skills development.

Do chronic diseases moderate the association between psychosocial working conditions and work exit? Longitudinal results from 55 950 Dutch workers

BACKGROUND

This study aims to examine whether the presence of chronic diseases or multimorbidity moderates the associations between psychosocial working conditions and work exit through unemployment, work disability or early retirement.

METHODS

Data from Lifelines (n=55 950), a prospective population-based cohort study, were enriched with monthly information on employment status from Statistics Netherlands. Working conditions were measured with the Copenhagen Psychosocial Questionnaire. Work exit was defined as unemployment, work disability and early retirement. Participants were classified as having no chronic disease, one chronic disease or multimorbidity. Cause-specific Cox proportional hazard regression models, adjusted for age, gender, education and partnership status, were used to analyse associations between working conditions and work exit. Interaction terms were used to examine moderation by chronic disease status.

RESULTS

Higher social support decreased the risk for unemployment, work disability and early retirement. Higher meaning of work decreased the risk of unemployment, and more possibilities for development decreased the risk for work disability. Chronic disease status did generally not moderate associations between working conditions and work exit. Only among workers without a chronic disease, more possibilities for development was associated with a lower risk for unemployment (HR: 0.89; 95% CI: 0.85 to 0.94).

CONCLUSION

While efforts to retain workers with chronic diseases in the labour market should continue, favourable psychosocial working conditions are important for all workers.

Psychosocial Working Conditions Play an Important Role in the Return-to-Work Process After Total Knee and Hip Arthroplasty

Purpose Both personal and work-related factors affect return to work (RTW) after total knee arthroplasty (TKA) and total hip arthroplasty (THA). Little is known about work-related factors associated with the recovery process. This study aimed to determine which work-related factors are associated with time to RTW for both TKA and THA patients. Methods A prospective multicenter survey study was conducted that included patients aged 18-63, had a paid job and were scheduled to undergo primary TKA/THA. Surveys were completed preoperatively, 6 weeks, and 3, 6, and 12 months postoperatively, and included four domains of work-related factors: work characteristics, physical working conditions, psychosocial working conditions and work adjustments. Control variables included age, sex, education, and comorbidity. Time to RTW was defined as days from surgery until RTW. Multivariate linear regression analyses were conducted separately for TKA/THA patients. Results Enrolled were 246 patients (n = 146 TKA, n = 100 THA, median age 56 years, 57% female). Median time to RTW was 79 days (IQR 52.0-146.0). Mainly physical tasks (TKA: B 58.2, 95%CI 9.5-106.8; THA: B 52.1, 95%CI 14.1-90.2) and a combination of physical and mental tasks (TKA: B 50.2, 95%CI 6.4-94.0; THA B 54.0, 95%CI 24.2-83.7) were associated with longer time to RTW after both TKA and THA. More possibilities for personal job development (B - 12.8, 95%CI - 25.3-0.4) and more work recognition (B - 13.2, 95%CI - 25.5 to - 0.9) were significantly associated with shorter time to RTW after TKA. Higher quality of supervisor leadership (B - 14.1, 95%CI - 22.2 to - 6.0) was significantly associated with shorter time to RTW after THA. Conclusion The findings of this study stress the importance of psychosocial working conditions, besides type of job tasks, in RTW after TKA/THA. Further research on work-related factors is needed, as arthroplasty is being performed on an increasingly younger population of knee and hip OA patients for whom participating in work is of critical importance.

Influence of social support on return to work after total hip or total knee arthroplasty: a prospective multicentre cohort study

OBJECTIVES

There is strong evidence that social support is an important determinant of return to work (RTW). Little is known about the role of social support in RTW after total hip or knee arthroplasty (THA/TKA). Objective was to examine the influence of preoperative and postoperative perceived social support on RTW status 6 months postoperatively.

DESIGN

A prospective multicentre cohort study was conducted.

SETTING

Orthopaedic departments of four Dutch medical centres; a tertiary university hospital, two large teaching hospitals and a general hospital.

PARTICIPANTS

Patients planned to undergo THA/TKA, aged 18-63 and employed preoperatively were included.

MAIN OUTCOME MEASURES

Questionnaires were filled out preoperatively and 3 and 6 months postoperatively and included questions to assess patients' perceived social support targeting three sources of social support: from home (friends, family), from work (coworkers, supervisors) and from healthcare (occupational physician, general practitioner, other caregivers). Control variables included age, gender, education, type of arthroplasty and comorbidities. RTW was defined as having fully returned to work 6 months postoperatively. Univariate and multivariate logistic regression analyses were conducted.

RESULTS

Enrolled were 190 patients (n=77 THA, n=113 TKA, median age was 56 years, 56% women). The majority returned to work (64%). Preoperatively, social support from the occupational physician was associated with RTW (OR 2.53, 95% CI 1.15 to 5.54). Postoperatively, social support from the occupational physician (OR 3.04, 95% CI 1.43 to 6.47) and the supervisor (OR 2.56, 95% CI 1.08 to 6.06) was associated with RTW.

CONCLUSIONS

This study underscores the importance of work-related social support originating from the occupational physician and supervisor in facilitating RTW after primary THA/TKA, both preoperatively and postoperatively. Further research is needed to confirm our results and to understand the facilitating role of social support in RTW, as arthroplasty is being performed on a younger population for whom work participation is critical.

Development and validation of a prediction model for unemployment and work disability among 55 950 Dutch workers

Background

This study developed prediction models for involuntary exit from paid employment through unemployment and disability benefits and examined if predictors and discriminative ability of these models differ between five common chronic diseases.

Methods

Data from workers in the Lifelines Cohort Study (n = 55 950) were enriched with monthly information on employment status from Statistics Netherlands. Potential predictors included sociodemographic factors, chronic diseases, unhealthy behaviours and working conditions. Data were analyzed using cause-specific Cox regression analyses. Models were evaluated with the C-index and the positive and negative predictive values (PPV and NPV, respectively). The developed models were externally validated using data from the Study on Transitions in Employment, Ability and Motivation.

Results

Being female, low education, depression, smoking, obesity, low development possibilities and low social support were predictors of unemployment and disability. Low meaning of work and low physical activity increased the risk for unemployment, while all chronic diseases increased the risk of disability benefits. The discriminative ability of the models of the development and validation cohort were low for unemployment (c = 0.62; c = 0.60) and disability benefits (c = 0.68; c = 0.75). After stratification for specific chronic diseases, the discriminative ability of models predicting disability benefits improved for cardiovascular disease (c = 0.81), chronic obstructive pulmonary disease (c = 0.74) and diabetes mellitus type 2 (c = 0.74). The PPV was low while the NPV was high for all models.

Conclusion

Taking workers’ particular disease into account may contribute to an improved prediction of disability benefits, yet risk factors are better examined at the population level rather than at the individual level.

Associations of within-individual changes in working conditions, health behaviour and BMI with work ability and self-rated health: a fixed effects analysis among Dutch workers

OBJECTIVES

This study assessed the associations of (1) within-individual improvements and (2) within-individual deteriorations in working conditions, health behaviour and body mass index (BMI) with changes in work ability and self-rated health among workers.

DESIGN

Prospective cohort study.

SETTING

The Netherlands.

PARTICIPANTS

Persons in paid employment, aged 45-64 years, who participated in the Dutch Study on Transitions in Employment, Ability and Motivation (STREAM) between 2010 and 2017, and improved or deteriorated at least once with respect to working conditions (psychological and emotional job demands, autonomy, social support, physical workload), health behaviour (moderate and vigorous physical activity, smoking status), or BMI between any of two consecutive measurements during the 7-year follow-up.

PRIMARY AND SECONDARY OUTCOME MEASURES

Changes in self-reported work ability on a scale from 0 to 10 (1st item of the work ability index) and self-rated health on a scale from 1 to 5 (SF-12).

RESULTS

Of the 21 856 STREAM participants, ultimately 14 159 workers were included in the fixed effects analyses on improvements (N=14 045) and deteriorations (N=14 066). Workers with deteriorated working conditions decreased in work ability (β's: -0.21 (95% CI: -0.25 to -0.18) to -0.28 (95% CI: -0.33 to -0.24)) and health (β's: -0.07 (95% CI: -0.09 to -0.06) to -0.10 (95% CI: -0.12 to -0.08)), whereas improvements were to a lesser extent associated with increased work ability (β's: 0.06 (95% CI: 0.02 to 0.09) to 0.11 (95% CI: 0.06 to 0.16)) and health (β's: 0.02 (95% CI: 0.00 to 0.03) to 0.04 (95% CI: 0.02 to 0.06)). Workers with increased BMI or decreased physical activity reduced in work ability and health. Likewise, decreased BMI or increased vigorous physical activity was associated with improved health. An increase in moderate or vigorous physical activity was modestly associated with a reduced work ability. Quitting smoking was associated with reduced work ability and health.

CONCLUSIONS

Compared with improvements, preventing deteriorations in working conditions, health behaviour and BMI, might be more beneficial for work ability and workers' health.

Comprehensive approach to reintegration of disability benefit recipients with multiple problems (CARm) into the labour market: results of a randomized controlled trial

PURPOSE

Although most clients on work disability benefits face multiple problems, most traditional interventions for (re)integration focus on a single problem. The aim of this study was to evaluate the "Comprehensive Approach to Reintegrate clients with multiple problems" (CARm), which provides a strategy for labour experts to build a relationship with each client in order to support clients in their needs and mobilize their social networks.

METHODS

This study is a stratified, two-armed, non-blinded randomized controlled trial (RCT), with a 12-month follow-up period. Outcome measures were: having paid work, level of functioning, general health, quality of life, and social support.

RESULTS

We included a total of 207 clients in our study; 97 in the intervention group and 110 in the care as usual (CAU) group. The clients' mean age was 35.4 years (SD 12.8), 53.1% were female, and 179 (86.5%) reported multiple problems. We found the CARm intervention to have no significant effects superior to those of the CAU group on all outcomes.

CONCLUSION

As we found no superior effect of the CARm intervention compared to CAU, we cannot recommend widespread adoption of CARm. A process evaluation will give more insight into possible implementation failure of the intervention. IMPLICATIONS FOR REHABILITATIONMost traditional interventions for (re)integration into the labour market are problem-centred, i.e., focusing on a single problem, and have limited effectiveness in persons with multiple problems.A strength-based intervention may be suitable for vocational rehabilitation and disability settings, since it contains many elements (e.g., being strength-based, focused on clients' wishes and goals, and involving activation of the social environment) also likely to improve chances of re-employment of persons with multiple problems.In this study a strength-based intervention did not show a superior effect on paid employment and functioning within one year follow-up compared to care as usual in people with multiple problems on a work disability benefit.

Multimorbidity and exit from paid employment: the effect of specific combinations of chronic health conditions

Background

This study aimed to assess the association between multimorbidity and exit from paid employment, and which combinations of chronic health conditions (CHCs) have the strongest association with exit from paid employment.

Methods

Data from 111 208 workers aged 18–64 years from Lifelines were enriched with monthly employment data from Statistics Netherlands. Exit from paid employment during follow-up was defined as a change from paid employment to unemployment, disability benefits, economic inactivity or early retirement. CHCs included cardiovascular diseases (CVD), chronic obstructive pulmonary disease (COPD), rheumatoid arthritis (RA), type 2 diabetes (T2DM) and depression. Cox-proportional hazards models were used to examine the impact of multimorbidity and combinations of CHCs on exit from paid employment.

Results

Multimorbidity increased the risk of exiting paid employment compared with workers without CHCs (hazard ratio (HR): 1.52; 95% confidence interval (CI): 1.35–1.71) or one CHC (HR: 1.14; 95% CI: 1.01–1.28). The risk for exit from paid employment increased among workers with COPD if they additionally had CVD (HR: 1.39; 95% CI: 1.03–1.88), depression (HR: 1.46; 95% CI: 1.10–1.93) or RA (HR: 1.44; 95% CI: 1.08–1.91), for workers with T2DM if they additionally had CVD (HR: 1.43; 95% CI: 1.07–1.91) or depression (HR: 2.09; 95% CI: 1.51–2.91) and for workers with depression who also had T2DM (HR: 1.68; 95% CI: 1.21–2.32).

Conclusion

This study showed that workers with multimorbidity, especially having a combination of COPD and depression or T2DM and depression, have a higher risk for early exit from paid employment and, therefore, may need tailored support at the workplace.

Exploring Employer Perspectives on Their Supportive Role in Accommodating Workers with Disabilities to Promote Sustainable RTW: A Qualitative Study

PURPOSE

Employers play an important role in facilitating sustainable return to work (RTW) by workers with disabilities. The aim of this qualitative study was to explore how employers who were successful in retaining workers with disabilities at work fulfilled their supportive role, and which facilitators were essential to support these workers throughout the RTW process.

METHODS

We conducted a semi-structured interview study among 27 employers who had experience in retaining workers with disabilities within their organization. We explored the different phases of RTW, from the onset of sick leave until the period, after 2-years of sick-leave, and when they can apply for disability benefit. We analyzed data by means of thematic analysis.

RESULTS

We identified three types of employer support: (1) instrumental (offering work accommodations), (2) emotional (encouragement, empathy, understanding) and (3) informational (providing information, setting boundaries). We identified three facilitators of employer support (at organizational and supervisor levels): (1) good collaboration, including (in)formal contact and (in)formal networks; (2) employer characteristics, including supportive organizational culture and leadership skills; and (3) worker characteristics, including flexibility and self-control.

CONCLUSIONS

Employers described three different possible types of support for the worker with disabilities: instrumental, emotional, and informational. The type and intensity of employer support varies during the different phases, which is a finding that should be further investigated. Good collaboration and flexibility of both employer and worker were reported as facilitators of optimal supervisor/worker interaction during the RTW process, which may show that sick-listed workers and their supervisors have a joint responsibility for the RTW process. More insight is needed on how this supervisor/worker interaction develops during the RTW process.

Exploring treatment adherence in long-term sick-listed workers and the impact of coping strategies, illness perceptions and perceived health

Background

Treatment adherence is important to improve return to work in sick-listed workers. Especially in long-term sick-listed workers who apply for a disability benefit and therefore have not (fully) returned to work, it is of great value to gain insight in the adherence to advice of physicians. Non-adherence could be one of the main reasons why they have not returned to work and are sick-listed for a long-term. The aim of the study is to explore treatment adherence and possible associated factors to advice from medical and occupational health physicians in long-term sick-listed workers.

Methods

The study is a cross-sectional survey study among 561 long-term (partly) sick-listed workers applying for a disability benefit. Associations of sociodemographic characteristics, disease related factors, coping strategies (Utrecht Coping List, UCL), illness perception (Illness Cognition Questionnaire, ICQ) and perceived health (Short-Form 12, SF12) with treatment adherence (measured with the Medical Outcomes Study Measures of Patient Adherence, MOS-MPA) were analysed separately for adherence to medical advice (n = 348, mean age 51.3 ± 9.1 years, 55.9% female) and adherence to occupational advice (n = 229, mean age 50.4 ± 9.5 years, 54.1% female).

Results

Among participants, 63.3% to 76.4% reported they were able to do what the physician told them to do. However, about half of the participants found it easy to follow-up and implement the suggestions of the physician (54.3% for medical advice and 50.2% for occupational advice). Having a mental health disorder was negatively associated with adherence to medical advice. An active coping strategy, acceptance of the disease, and perceiving positive long-term consequences of the disease were associated with a higher adherence, whereas focusing on the negative consequences was associated with a lower adherence, both for medical and occupational advice.

Conclusions

The tendency to adhere to medical and occupational advice in long-term sick-listed workers is relatively low. In order to increase return to work in this population, medical and occupational health physicians should especially be aware of the adherence of sick-listed workers with mental health disorders, but also on those who focus on the negative consequences of their (physical or mental health) disorder.

Inability to Work Fulltime, Prevalence and Associated Factors Among Applicants for Work Disability Benefit

Purpose Inability to work fulltime is an important outcome in the assessment of workers applying for a disability benefit. However, limited knowledge is available about the prevalence and degree of the inability to work fulltime, the associations between disease-related and socio-demographic factors with inability to work fulltime and whether the prevalence and the associations differ across disease groups. Methods Anonymized register data on assessments of workers with residual work capacity (n = 30,177, age 48.8 ± 11.0, 53.9% female) applying for a work disability benefit in 2016 were used. Inability to work fulltime was defined as being able to work less than 8 h per day. Results The prevalence of inability to work fulltime was 39.4%, of these 62.5% could work up to 4 h per day. Higher age (OR 1.01, 95% CI 1.01-1.01), female gender (OR 1.45, 95% CI 1.37-1.52), higher education (OR 1.44, 95% CI 1.33-1.55) and multimorbidity (OR 1.06, 95% CI 1.01-1.11) showed higher odds for inability to work fulltime. Highest odds for inability to work fulltime were found for diseases of the blood, neoplasms and diseases of the respiratory system. Within specific disease groups, different associations were identified between disease-related and socio-demographic factors. Conclusion The prevalence and degree of inability to work fulltime in work disability benefit assessments is high. Specific chronic diseases are found to have higher odds for inability to work fulltime, and associated factors differ per disease group.

The Role of the Employer in Supporting Work Participation of Workers with Disabilities: A Systematic Literature Review Using an Interdisciplinary Approach

Purpose There is growing awareness that the employer plays an important role in preventing early labor market exit of workers with poor health. This systematic review aims to explore the employer characteristics associated with work participation of workers with disabilities. An interdisciplinary approach was used to capture relevant characteristics at all organizational levels. Methods To identify relevant longitudinal observational studies, a systematic literature search was conducted in PubMed, Web of Science, PsycINFO and EconLit. Three key concepts were central to the search: (a) employer characteristics, (b) work participation, including continued employment, return to work and long-term work disability, and (c) chronic diseases. Results The search strategy resulted in 4456 articles. In total 50 articles met the inclusion criteria. We found 14 determinants clustered in four domains: work accommodations, social support, organizational culture and company characteristics. On supervisor level, strong evidence was found for an association between work accommodations and continued employment and return to work. Moderate evidence was found for an association between social support and return to work. On higher organizational level, weak evidence was found for an association between organizational culture and return to work. Inconsistent evidence was found for an association between company characteristics and the three work outcomes. Conclusions Our review indicates the importance of different employer efforts for work participation of workers with disabilities. Workplace programs aimed at facilitating work accommodations and supervisor support can contribute to the prevention of early labor market exit of workers with poor health. Further research is needed on the influence of organizational culture and company characteristics on work participation.

Employer perspectives on their supportive role in promoting sustainable RTW of disabled workers

Background

Employers play an important supportive role in facilitating sustainable Return to Work (RTW) of workers with disabilities. Little is understood about how employers deal with their supportive role, what kind of support they offer and which facilitators of employer support are important to successful RTW.

Methods

A semi-structured interview study was conducted among 27 employer representatives (e.g. supervisors, HR managers, case managers) of companies in the Netherlands who had experience in retaining at least one disabled workers within their company. Participants were included through purposive sampling on sector and company size. Data was analyzed by means of thematic analysis.

Results

We identified three different types of employer support: 1. instrumental support (offering work accommodations), 2. emotional support (encouragement, empathy, understanding) and 3. informational support (providing information, setting boundaries). Facilitators of employer support were categorized into three main themes: 1. good collaboration, with subthemes (in)formal contact, trustful relationships, mutual responsibilities and (in)formal networks, 2. employer characteristics, including supportive organizational culture, leadership skills and flexibility, and 3. employee characteristics including flexibility and resilience.

Conclusions

Different types of employer support are considered as important in the RTW process of disabled workers. Besides offering work accommodations, also emotional and informational support are necessary. In addition, good collaboration and flexibility of both employer and employee may be viewed as facilitators for optimizing supervisor and employee interaction during the RTW process.

Key messages

Instrumental, emotional and informational support by the employer are important in the RTW process of disabled workers. Facilitating factors include collaboration, flexibility and leadership.

The impact of changes in working conditions, health behavior and BMI on work ability and health

Background

Research on how to improve work ability and health of workers is essential for prolongation of working lives. Therefore, this study assessed the impact of 1) within-individual improvements, and 2) within-individual deteriorations in working conditions, health behavior and BMI on changes in work ability and self-rated health among workers.

Methods

The Dutch Study on Transitions in Employment, Ability and Motivation (STREAM) was used to identify participants whose working conditions, health behavior, and BMI improved (N = 14,045) or deteriorated (N = 14,066) at least once during 7 year follow-up (2010-2017). The impact of within-individual improvements and deteriorations in health behavior (moderate- and vigorous physical activity, smoking status), BMI, psychosocial (psychological- and emotional job demands, autonomy, social support) and physical working conditions in a given year on changes in work ability (0-10 scale) and self-rated health (1-5 scale) in the same year were analyzed with fixed-effects regression models.

Results

Workers with deteriorated physical or psychosocial working conditions decreased in work ability (β's:-0.21 (95%CI: -0.25;-0.18) to -0.28 (95%CI: -0.33;-0.24)) and health (β's:-0.07 (95%CI: -0.09;-0.06) to -0.10 (95%CI: -0.12;-0.08)), whereas improvements were to a lesser extent associated with increased work ability (β's: 0.06 (95%CI: 0.02;0.09) to 0.11 (95%CI: 0.06;0.16)) and health (β's: 0.02 (95%CI: 0.00;0.03) to 0.04 (95%CI: 0.02;0.06)). Decreased physical activity and increased BMI were associated with reduced work ability and health. Workers whose BMI decreased or vigorous physical activity increased improved in health, but those with increased moderate or vigorous physical activity reduced in work ability. Quitting smoking was associated with reduced work ability and health.

Conclusions

Preventing deteriorations in working conditions and health behavior could be of importance for sustainable employability.

Key messages

Modification of working conditions and health promotion might contribute to sustained employability. Preventing deteriorations in working conditions might be of particular importance for prolongation of working lives.

Exploring the concept inability to work fulltime in the context of work disability assessments: a qualitative study

Background

In many countries inability to work fulltime is recognized as an important concept in work disability assessments. However, consensus is lacking regarding the concept and how it should be assessed. This study seeks to conceptualize and operationalize the concept of inability to work fulltime, and includes perspectives of both patients and physicians. Research questions involve identifying: 1. key elements, 2. measurable indicators, and 3. valid methods for assessing indicators of inability to work fulltime.

Methods

We used a qualitative study with a thematic content analysis design to conceptualize inability to work fulltime, based on nineteen semi-structured interviews conducted among insurance and occupational health physicians, and representatives of patient organizations.

Results

Inability to work fulltime is conceptualized as a complex concept which is strongly individually determined and variable due to time and underlying disease. Key dimensions of inability to work fulltime included besides the disease itself, also personal factors like psychological and lifestyle factors, as well as environmental factors related to the work situation and social context. Fatigue, cognitive impairments, and restrictions in functioning in- and outside work were reported as important measurable indicators. A combined use of self-assessment, assessment interviews, and testing, and assessment in the actual (work) setting was identified for assessing these indicators.

Conclusion

Taking into account the complex and variable nature of inability to work fulltime, we found it advisable to use multiple methods and multiple time points for the assessment. Results of this study provide starting points for further research on the operationalization of inability to work fulltime in a work disability context.

1225Symptoms of depression and anxiety in Dutch adults during and before the COVID-19 pandemic

Background

The COVID-19 pandemic may impact mental health outcomes differentially based on an inidivdual’s capital, i.e. resources used to maintain and enhance health. This study examined changes in depression and anxiety symptoms before and during the pandemic, and assessed their association with different elements of capital.

Methods

Data from 65,854 individuals (Mage=50.4, SDage=12.0) from the Lifelines COVID-19 cohort were used. Baseline mental health symptoms were on average measured 4.7 (SD = 1.1) years before the first COVID-19 measurement wave (T1), and subsequent waves were (bi)weekly (March 30 — August 05, 2020). Mental health symptom trajectories were estimated using a two-part Latent Class Growth Analysis (cutoff=2 symptoms), and class membership was predicted by several elements of economic (education, income, and occupation) and person capital (neuroticism).

Results

Most individuals were unlikely to report □2 symptoms of depression (80.6%) and anxiety (75.9%), but small stable-high classes for both conditions were identified (1.6% and 6.7%, respectively). Compared to T0, T1 showed increases in the mean number of symptoms (Mdep_t0=4.1 vs Mdep_t1=4.7, Manx_t0=4.2 vs Manx_t1=4.3) and probability of reporting symptoms (Probdep_t0=0.65 vs Probdep_t1=0.96, Probanx_t0=0.70 vs Probanx_t1=0.92). Lower income (ORdep=1.10; 95%CI:1.05-1.16; ORanx=1.05; 95%CI:1.02-1.07) and higher neuroticism (ORdep=1.10; 95%CI:1.09-1.11; ORanx=1.08; 95%CI:1.08-1.09) increased the odds of being in both stable-high classes. Low education increased the odds of being in the stable-high depression class (ORdep=1.46; 95%CI:1.07-1.99), and higher occupation increased the odds of being in the stable-high anxiety class (ORanx=1.06; 95%CI:1.03-1.09).

Conclusion

Overall, a minority of individuals, who generally possessed less capital, reported an increase in symptoms of depression or anxiety.

Key message

Inidividuals with less capital, i.e. resources, generally experienced more symptoms of depression and anxiety, which stresses the importance of devoting more resources to improve their mental health.

Recovery Courses of Patients Who Return to Work by 3, 6 or 12 Months After Total Knee Arthroplasty

Purpose This study compared the preoperative levels and postoperative recovery courses of physical and mental impairments, activity limitations and participation restrictions of working-age patients who return to work (RTW) by 3, 6 or 12 months after total knee arthroplasty (TKA). Methods A prospective survey study including TKA patients (aged < 65) (n = 146) who returned to work (RdTW) in the first postoperative year. Three groups were compared: those who returned by 3 (n = 35), 6 (n = 40) or 12 (n = 29) months. Surveys were completed preoperatively and at 6 weeks and 3, 6 and 12 months postoperatively. Outcomes represented domains of the International Classification of Functioning, i.e. physical impairments (pain, stiffness, vitality), mental impairments (mental health and depressive symptoms), activity limitations (physical functioning) and participation restrictions (social and work functioning). Results Preoperative knee-specific pain and physical functioning levels were better among patients who RdTW by 3 months, compared to those who returned by 12 months. Patients who RdTW by 3 months experienced significantly better recovery from physical impairments than those who returned by 6 months (on general pain) or 12 months (on general and knee-specific pain and on stiffness). Patients returning by 3 months experienced significantly better recovery from activity limitations (on knee-specific physical functioning). Conclusions To optimize return to work outcome after TKA surgery, the focus should lie on physical impairments (general and knee-specific pain, stiffness) and activity limitations (knee-specific physical functioning) during recovery.

Barriers to and Facilitators of Sustained Employment: A Qualitative Study of Experiences in Dutch Patients With CKD

RATIONALE & OBJECTIVE

Although patients with chronic kidney disease (CKD) are at risk for work disability and loss of employment, not all experience work disruption. We aimed to describe the barriers to and facilitators of sustained employment experienced by Dutch patients with CKD.

STUDY DESIGN

Qualitative study using semistructured interviews.

SETTING & PARTICIPANTS

27 patients with CKD glomerular filtration rate categories 3b-5 (G3b-G5) from 4 nephrology outpatient clinics in The Netherlands.

ANALYTICAL APPROACH

Content analyses with constant comparison of interview data based on the International Classification of Functioning, Disability and Health framework.

RESULTS

Participants were 6 patients with CKD G3b-G4, 8 patients receiving maintenance dialysis, and 13 patients with functioning kidney transplants. We identified health-related barriers (symptoms, physical toll of dialysis/transplantation, limited work capacity) and facilitators (few physical symptoms, successful posttransplantation recovery, absence of comorbidities, good physical condition), personal barriers (psychological impact, limited work experience) and facilitators (positive disposition, job satisfaction, work attitude, person-job fit), and environmental barriers and facilitators. Environmental barriers were related to nephrology care (waiting time, use of a hemodialysis catheter) and work context (reorganization, temporary contract, working hours, physical demands); environmental facilitators were related to nephrology care (personalized dialysis, preemptive transplant), work context (large employer, social climate, job requiring mental rather than physical labor, flexible working hours, adjustment of work tasks, reduced hours, remote working, support at work, peritoneal dialysis exchange facility), and support at home. Occupational health services and social security could be barriers or facilitators.

LIMITATIONS

The study sample of Dutch patients may limit the transferability of these findings to other countries.

CONCLUSIONS

The wide range of barriers and facilitators in all International Classification of Functioning, Disability and Health components suggests great diversity among patients and their circumstances. These findings underline the importance of personalized nephrology and occupational health care as well as the importance of individually tailored workplace accommodations to promote sustained employment for patients with CKD.

Accelerometer Measured Sedentary and Physical Activity Behaviors of Working Patients after Total Knee Arthroplasty, and their Compensation Between Occupational and Leisure Time

Purpose Objective measurements of sedentary and physical activity (PA) behavior are scarce among working-age patients who undergo total knee arthroplasty (TKA). Aim was to assess sedentary and PA behaviors using accelerometers and to identify compensation effects between occupational and leisure time of sedentary and PA behavior. Methods One year post-TKA, 51 patients wore an ActiGraph(GT3x) accelerometer for 7 days. Sedentary time, prolonged sedentary bouts (≥ 30 min) and PA (light-intensity and moderate-to-vigorous PA) were examined. Compliance with the guideline of > 150 min moderate-to-vigorous PA per week was calculated. Compensation effects were analyzed using multilevel models, splitting effects into routine and within-day compensation, stratifying by physical and non-physical jobs. The routine compensation effects are the ones of interest, representing habitual compensation during a week. Results Participants spent 60% of time in sedentary bouts and 17% in prolonged sedentary bouts, with 37% of PA spent in light-intensity and 3% in moderate-to-vigorous activity. About 70% of patients met the PA guideline. Routine compensation effects were found for workers in physical jobs, who compensated for their occupational light-intensity PA with less light-intensity PA during leisure time. Workers in non-physical jobs did not compensate for their occupational prolonged sedentary bouts, as these continued during leisure time. Conclusion This study showed that working TKA patients are highly sedentary 1 year after surgery, but most met the PA guideline. Especially those with non-physical jobs do not compensate for their occupational prolonged sedentary bouts. This stresses the need to stimulate PA among TKA patients not complying with the guidelines and those with non-physical jobs.

Content Validation of a Practice-Based Work Capacity Assessment Instrument Using ICF Core Sets

PURPOSE

A shift from providing long-term disability benefits to promoting work reintegration of people with remaining work capacity in many countries requires new instruments for work capacity assessments. Recently, a practice-based instrument addressing biopsychosocial aspects of functioning, the Social Medical Work Capacity instrument (SMWC), was developed. Our aim was to examine the content validity of the SMWC using ICF core sets.

METHODS

First, we conducted a systematic search to identify relevant ICF core sets for the working age population. Second the content of these core sets were mapped to assess the relevance and comprehensiveness of the SMWC. Next, we compared the content of the SMWC with the ICF-core sets.

RESULTS

Two work-related core sets and 31 disease-specific core sets were identified. The SMWC and the two work-related core sets overlap on 47 categories. Compared to the work-related core sets, the Body Functions and Activities and Participation are well represented in the new instrument, while the component Environmental factors is under-represented. Compared to the disease-specific core sets, items related to the social and domestic environmental factors are under-represented, while the SMWC included work-related factors complementary to the ICF.

CONCLUSION

The SMWC content seems relevant, but could be more comprehensive for the purpose of individual work capacity assessments. To improve assessing relevant biopsychosocial aspects, it is recommended to extend the instrument by adding personal and environmental (work- and social-related) factors as well as a more tailored use of the SMWC for assessing work capacity of persons with specific diseases or underlying illness.

The contribution of employer characteristics to continued employment of employees with residual work capacity: evidence from register data in The Netherlands

Objectives:

This study aimed to examine the contribution of employer characteristics to continued employment of employees with residual work capacity. Moreover, we examined whether the contribution of employer characteristics differs across types of employers and employees’ types of diseases.

Methods:

Register data on disability assessments and employment status of N=84 394 long-term sick-listed employees with residual work capacity were obtained from the Dutch Employee Insurance Agency between 2010 and 2017. The dependent variable was continued employment four months after the assessment. We linked employees to their (former) employer to measure sector, firm size, and workforce composition. The average employment outcome of all employees assessed in the same firm and year served as a proxy measure for the extent of implemented disability-related policies and practices. Using multilevel multiple regression analysis, we compared the relative contribution of employer characteristics with employees’ characteristics.

Results:

Employer characteristics accounted for 10% of the variability in employment outcomes. In comparison, employees’ socio-demographic and disease characteristics accounted for 13% of the variability. The prevalence of continued employment was lowest in smaller firms and construction and low-wage service-orientated sectors. Furthermore, there were sizeable differences in employment outcomes between similar employers in terms of size, sector and workforce-composition, particularly between larger firms and among employees with mental or musculoskeletal disorders compared to other diseases.

Conclusions:

This study shows substantial differences between employers in facilitating continued employment of employees with residual work capacity. Encouraging firms to invest more in disability-related policies and practices may result in better employment opportunities for these employees.

The courses of objective physical activity and the association with sleepiness during a 2-week-on/2-week-off offshore shift rotation: an observational repeated-measures study

BACKGROUND

Offshore workers are assumed to have poor health behaviours, but no studies have yet examined physical activity (PA) during a full offshore shift rotation period, including both work and at home periods. Furthermore, the relationship of PA with sleepiness, a prevalent safety hazard offshore, is not known. This study aimed to examine (1) the courses of objectively measured PA in offshore workers during pre-, offshore and post-offshore periods, and (2) the association between PA and self-reported sleepiness.

METHODS

An observational repeated measures study was conducted among 36 offshore workers during a full 2-week on/2-week off offshore shift rotation. Objective PA was assessed using Daytime Activity Averages (DAA) from actigraph recordings. Sleepiness was assessed using next-morning Karolinska Sleepiness Scale (KSS) scores. The courses of PA over time were analysed with Linear Mixed Models (LMM). Parallel LMM were used to assess the longitudinal relationship between PA and sleepiness, both on a between-person and within-person level.

RESULTS

The courses of PA were not significantly different between the pre-, offshore, and post-offshore periods. In addition, between-person trends of PA and sleepiness were not associated (p ranges between 0.08─0.99) and PA did not affect next-morning sleepiness on a within-person level (p = 0.15).

CONCLUSIONS

PA levels during the offshore working period were not different from PA levels at home. Furthermore, PA was not associated with next-morning sleepiness. Further research should focus on different levels of PA including its intensity level.

Prevalence, types, and combinations of multiple problems among recipients of work disability benefits

PURPOSE

For persons on disability benefits who are facing multiple problems, active labour market policies seem less successful. Besides health problems, these people perceive personal, social, and environmental problems. Since very little is known about these "non-medical" problems our aim was to explore the prevalence of clients experiencing multiple problems, the types and number of perceived problems, combinations of perceived problems, and associated characteristics in a group of work disability benefit recipients.

METHODS

We performed a cross-sectional study, using self-reported data on perceived problems and socio-demographics, and register data from the Dutch Social Security Institute on diagnosed diseases and employment status. A convenient group of labour experts recruited eligible clients on work disability benefit.

RESULTS

Of the 207 persons on work disability benefit, 87% perceived having multiple problems. Most reported problems were related to physical (76%) or mental (76%) health. Health problems most frequently occurred together with a mismatch in education, financial problems, or care for family members. Clients with lower education experienced significantly more problems than clients with an intermediate or high educational level.

CONCLUSIONS

Clients with multiple problems face severe and intertwined problems in different domains of life, and need tailored multi-actor work disability management.Implications for rehabilitationClients with multiple problems face severe and intertwined problems in different domains of life; therefore, interventions tailored to deal with needs related to specific problems might be more effective than traditional programs.Interventions should match experienced barriers, and involve multi-actor work disability management with all the challenges of mutual cooperation.For persons with multiple problems a focus on pure medical barriers is too narrow, because personal, social, and environmental factors might also obstruct participation in work.

Lifelines COVID-19 cohort: investigating COVID-19 infection and its health and societal impacts in a Dutch population-based cohort

PURPOSE

The Lifelines COVID-19 cohort was set up to assess the psychological and societal impacts of the COVID-19 pandemic and investigate potential risk factors for COVID-19 within the Lifelines prospective population cohort.

PARTICIPANTS

Participants were recruited from the 140 000 eligible participants of Lifelines and the Lifelines NEXT birth cohort, who are all residents of the three northern provinces of the Netherlands. Participants filled out detailed questionnaires about their physical and mental health and experiences on a weekly basis starting in late March 2020, and the cohort consists of everyone who filled in at least one questionnaire in the first 8 weeks of the project. FINDINGS TO DATE: >71 000 unique participants responded to the questionnaires at least once during the first 8 weeks, with >22 000 participants responding to seven questionnaires. Compiled questionnaire results are continuously updated and shared with the public through the Corona Barometer website. Early results included a clear signal that younger people living alone were experiencing greater levels of loneliness due to lockdown, and subsequent results showed the easing of anxiety as lockdown was eased in June 2020.

FUTURE PLANS

Questionnaires were sent on a (bi)weekly basis starting in March 2020 and on a monthly basis starting July 2020, with plans for new questionnaire rounds to continue through 2020 and early 2021. Questionnaire frequency can be increased again for subsequent waves of infections. Cohort data will be used to address how the COVID-19 pandemic developed in the northern provinces of the Netherlands, which environmental and genetic risk factors predict disease susceptibility and severity and the psychological and societal impacts of the crisis. Cohort data are linked to the extensive health, lifestyle and sociodemographic data held for these participants by Lifelines, a 30-year project that started in 2006, and to data about participants held in national databases.
