Work functioning of Dutch workers with a chronic disease in early, mid and late working life: Cross-sectional findings from 38,470 participants in the Lifelines Cohort Study.

Insight into the work functioning of workers with chronic diseases may help to improve their sustainable employability. This study examines the work functioning of workers with cardiovascular disease (CVD), diabetes mellitus type 2 (DM2), chronic obstructive pulmonary disease (COPD), rheumatoid arthritis and depression across early, mid, and late working life. This cross-sectional study used data from 38,470 participants of the Dutch Lifelines study. Chronic diseases were classified based on clinical measures, self-reports, and medication. Work functioning was measured with the Work Role Functioning Questionnaire (WRFQ), covering work scheduling and output demands, physical demands, mental and social demands, and flexibility demands. Multivariable linear and logistic regression analyses were used to examine associations between chronic diseases and work functioning (continuous) and low work functioning (dichotomous). Depression was associated with lower work functioning across all subscales and working life stages, with the lowest score in the work scheduling and output demands subscale in late working life (B:-9.51;95%CI:-11.4,-7.65). Rheumatoid arthritis was most strongly associated with lower work functioning in the physical demands subscale, with the lowest score in early working life (B:-9.97;95%CI:-19.0,-0.89). Associations between CVD and DM2 and work functioning were absent in early working life but present in mid and late working life. Associations between COPD and work functioning were absent in mid working life but present in late working life. Occupational health professionals could use the WRFQ to identify workers' perceived difficulties in meeting specific work demands, pointing out directions for interventions to mitigate perceived difficulties and thereby improve sustainable employability.

Prevention of sick leave at the workplace: design of a cluster-randomized controlled trial of a problem-solving intervention among employees with common mental disorders.

BACKGROUND: Common mental disorders are highly prevalent in the working population, affecting about 1 in 5 persons in the Organisation for Economic Co-operation and Development countries. About 30% of those affected have a first period of sick leave. Despite several attempts to reduce the risk of sick leave among employees with common mental disorders, there is a lack of knowledge about effective, preventive interventions which aim to reduce such risks. This protocol describes the design of a study to evaluate the effectiveness of a problem-solving intervention delivered by first-line managers to employees with common mental disorders on the prevention of sick leave during the 12-month follow-up. METHODS/DESIGN: The study applies a two-armed cluster-randomized trial design of a problem-solving intervention conducted in private-sector companies. First-line managers are randomized into intervention- or control groups by computer-generated random numbers, allocation ratio 1:1. Employees are eligible if at risk for future sick leave due to common mental disorders. These are identified by self-reported psychological health measured by the General Health Questionnaire 12-item, cut-off ≥3, or a positive answer to risk of sick leave. The intervention is based on problem-solving principles. It involves the training of the first-line managers who then deliver the intervention to employees identified at risk of sick leave. First-line managers in the control group receives a lecture. Primary outcome is number of registered days of sick leave due to common mental disorders during the 12-month follow-up. Secondary outcomes are general health, psychological symptoms, work performance, work ability and psychosocial work environment. A process evaluation will examine the intervention's reach, fidelity, dose delivered, dose received, satisfaction and context. Research assistants managing the screening procedure, outcome assessors and employees are blinded to randomization and allocation. DISCUSSION: The study includes analyses of the intervention's effectiveness and an alongside process evaluation. Methodological strengths and limitations, for example the risk of selection bias, attrition and risk of contamination are discussed.

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.

Social position and geriatric syndromes among Swedish older people: a population-based study.

BACKGROUND: Older people with a low social position are at higher risk of poor health outcomes compared to those with a higher social position. Whether lower social position also increases the risk of geriatric syndromes (GSs) remains to be determined. This study investigates the association of social position with GSs among older community-dwellers. METHODS: Three consecutive population-based health surveys in 2006, 2010 and 2014 among older community-dwellers (age 65-84 years) in Stockholm County were combined (n = 17,612) and linked with Swedish administrative registry information. Social position was assessed using registry information (i.e. education, country of origin and civil status) and by self-reports (i.e. type of housing and financial stress). GSs were assessed by self-reports of the following conditions: insomnia, urinary incontinence, functional decline, falls, depressive disorder, hearing or vision problems. Binomial logistic regression analyses were used to estimate the association between social position and GSs after adjusting for age, sex, health status, health behavior and social stress. RESULTS: The prevalence of GSs was 70.0%, but varied across GSs and ranged from 1.9% for depression to 39.1% for insomnia. Living in rented accommodation, being born outside the Nordic countries, being widowed or divorced were associated with GS presence. Financial stress was most strongly associated with GSs (adjusted odds ratio, 2.59; 95% CI, 2.13-3.15). CONCLUSION: GSs are highly prevalent among older Swedish community-dwellers with wide variations across syndromes and strong association with all measures of social position, most strikingly that of experiencing financial stress.

Does early identification of work-related stress, combined with feedback at GP-consultation, prevent sick leave in the following 12 months? a randomized controlled trial in primary health care.

BACKGROUND: Experiencing work-related stress constitutes an obvious risk for becoming sick-listed. In primary health care, no established method to early identify, advise and treat people with work-related stress exists. The aim was to evaluate if the use of the Work Stress Questionnaire (WSQ) brief intervention, including feedback from the general practitioner (GP), had an impact on the level of sickness absence. METHOD/DESIGN: In total 271 (intervention group, n = 132, control group, n = 139) non-sick-listed employed women and men, aged 18 to 64 years, who had mental and physical health complaints and sought care at primary health care centers participated in this two-armed randomized controlled trial. The main outcomes were the number of registered sick leave days and episodes, and time to first sick leave during the 12-months follow-up. The intervention included early identification of work-related stress by the WSQ, GP awareness supported by a brief training session, patients' self-reflection by WSQ completion, GP feedback at consultation, and initiation of preventive measures. RESULTS: The mean days registered for the WSQ intervention group and the control group were 39 and 45 gross days respectively, and 31 and 39 net days respectively (ns). No statistical significant difference for the number of sick leave episodes or time to first day of sick leave episode were found between the groups. CONCLUSIONS: The WSQ brief intervention combined with feedback and suggestions of measures at patient-GP-consultation was not proven effective in preventing sick leave in the following 12 months compared to treatment as usual. More research is needed on methods to early identify, advise and treat people with work-related stress in primary health care, and on how and when GPs and other professionals in primary health care can be trained to understand this risk of sick leave due to work-related stress, on how to prevent it, and on how to advise and treat employees at risk.

Work-specific cognitive symptoms and the role of work characteristics, fatigue, and depressive symptoms in cancer patients during 18 months post return to work.

OBJECTIVE: Cancer patients can experience work-specific cognitive symptoms post return to work. The study aims to (1) describe the course of work-specific cognitive symptoms in the first 18 months post return to work and (2) examine the associations of work characteristics, fatigue and depressive symptoms with work-specific cognitive symptoms over time. METHODS: This study used data from the 18-month longitudinal "Work Life after Cancer" cohort. The Cognitive Symptom Checklist-Work Dutch Version (CSC-W DV) was used to measure work-specific cognitive symptoms. Linear mixed models were performed to examine the course of work-specific cognitive symptoms during 18-month follow-up; linear regression analyses with generalized estimating equations were used to examine associations over time. RESULTS: Working cancer patients examined with different cancer types were included (n = 378). Work-specific cognitive symptoms were stable over 18 months. At baseline, cancer patients reported more working memory symptoms (M = 32.0; CI, 30.0-34.0) compared with executive function symptoms (M = 19.3; CI, 17.6-20.9). Cancer patients holding a job with both manual and nonmanual tasks reported less work-specific cognitive symptoms (unstandardized regression coefficient b = -4.80; CI, -7.76 to -1.83) over time, compared with cancer patients with a nonmanual job. Over time, higher depressive symptoms were related to experiencing more overall work-specific cognitive symptoms (b = 1.27; CI, 1.00-1.55) and a higher fatigue score was related to more working memory symptoms (b = 0.13; CI, 0.04-0.23). CONCLUSIONS: Job type should be considered when looking at work-specific cognitive symptoms over time in working cancer patients. To reduce work-specific cognitive symptoms, interventions targeted at fatigue and depressive symptoms might be promising.

Number of medications and adverse drug events by unintentional poisoning among older adults in consideration of inappropriate drug use: a Swedish population-based matched case-control study.

PURPOSE: This national, population-based study aims to determine the association between the number of prescribed medications and adverse drug events (ADE) by unintentional poisoning and examine this risk when known indicators of inappropriate drug use (IDU) are accounted for. METHODS: We employed a matched case-control design among people living in Sweden who were 50 years and older. Cases experiencing an ADE by unintentional poisoning resulting in hospitalization or death (n = 5336) were extracted from the National Health and Death Registers from January 2006 to December 2009. Four controls per case matched by age, sex and residential area were randomly selected among those without an ADE (n = 21,344). Prescribed medications dispensed during the 4-month period prior to the ADE were identified via the Swedish Prescribed Drug Register and coded according to the number of different dispensed medications (NDDM) (0 to 10 medications) and IDU indicators (one single-drug, and three drug-combinations). Conditional logistic regression was used. RESULTS: Each of the IDU indicators was significantly associated with very high risks of ADE. For NDDM, we found a lower but graded positive association from two to ten or more medications (adjusted OR, 1.5; 95% CI, 1.2-1.8). Exclusion of IDU from the NDDM decreased the risk of ADE, but the effects remained significant for three or more medications (adjusted OR excl. IDU, 1.5; 95% CI, 1.2-2.0). CONCLUSION: At population level, the number of different dispensed medications starting from three or more remains associated with ADE even after adjusting for known IDUs. Clinicians and patients need to be made aware of the increased likelihood of serious ADE, not only in case of documented inappropriate medications but also in the case of an increasing number of medications.

Injurious falls and subsequent adverse drug events among elderly - a Swedish population-based matched case-control study.

BACKGROUND: Fall injuries are stressful and painful and they have a range of serious consequences for older people. While there is some clinical evidence of unintentional poisoning by medication following a severe fall injuries, population-based studies on that association are lacking. This is investigated in the current study, in which attention is also paid to different clinical conditions of the injured patients. METHODS: We conducted a matched case-control study of Swedish residents 60 years and older from various Swedish population-based registers. Cases defined as adverse drug events (ADE) by unintentional poisoning leading to hospitalization or death were extracted from the National Patient Register (NPR) and the Cause of Death Register from January 2006 to December 2009 (n = 4418). To each case, four controls were matched by sex, age and residential area. Information on injurious falls leading to hospitalization six months prior to the date of hospital admission or death from ADE by unintentional poisoning, and corresponding date for the controls, was extracted from the NPR. Data on clinical conditions, such as dispensed medications, comorbidity and previous fall injuries were also extracted from the Swedish Prescribed Drug Register (SPDR) and NPR. Effect estimates were calculated using conditional logistic regression and presented as odds ratios (OR) and 95% confidence intervals (CI). RESULTS: We found a three-fold increased risk of unintentional poisoning by medication in the six-month period after an injurious fall (OR 3.03; 95% CI, 2.54-3.74), with the most pronounced increase 1-3 weeks immediately after (OR, 7.66; 95% CI, 4.86-12.1). In that time window, from among those hospitalized for a fall (n = 92), those who sustained an unintentional poisoning (n = 60) tended to be in poorer health condition and receive more prescribed medications than those who did not, although this was not statistically significant. Age stratified analyses revealed a higher risk of poisoning among the younger (aged 60-79 years) than older elderly (80+ years). CONCLUSION: Medication-related poisoning leading to hospitalization or death can be an ADE subsequent to an episode of hospitalization for a fall-related injury. Poisoning is more likely to occur closer to the injurious event and among the younger elderly. It cannot be ruled out that some of those falls are themselves ADE and early signs of greater vulnerability among certain patients.

Beyond Return to Work: The Effect of Multimorbidity on Work Functioning Trajectories After Sick Leave due to Common Mental Disorders.

Objectives Patients with common mental disorders (CMDs) often suffer from comorbidities, which may limit their functioning at work. We assessed the longitudinal impact of multimorbidity, defined as two or more co-occurring chronic health conditions, on work functioning over time among workers who had returned to work after sick leave due to CMDs. Methods Prospective cohort study of 156 workers followed for 1 year after return to work from sick leave due to CMDs. A multimorbidity score was computed by counting severity-weighted chronic health conditions measured at baseline. Work functioning was measured at baseline and at 3, 6 and 12 months follow-up with the Work Role Functioning Questionnaire. Work functioning trajectories, i.e. the course of work functioning after return to work over time, were identified through latent class growth analysis. Results A total of 44 % of workers had multimorbidity. Four work functioning trajectories were identified: one (12 % of the workers) showed increasing work functioning scores during follow-up, whereas the other trajectories showed low, medium and high scores (23, 41 and 25 %, respectively) that remained stable across time points. Although multimorbidity did not predict membership in any trajectory, within the increasing score trajectory levels of work functioning were lower among those with high baseline multimorbidity score (p < 0.001). Conclusions Over time, multimorbidity negatively impacts work functioning after return to work from sick leave due to CMDs.

Employees' Perceptions of Social Norms as a Result of Implementing the Participatory Approach at Supervisor Level: Results of a Randomized Controlled Trial.

Purpose A multifaceted implementation strategy was targeted at supervisors to encourage them to apply a participatory approach (PA) in dealing with employees' work functioning problems due to health concerns. This paper assesses the effect on employees' perceived social norms regarding the use of the PA to deal with work functioning problems. Methods Three organizations participated in a cluster randomized controlled trial, with randomization at the department level. Supervisors in the PA intervention departments received the implementation strategy consisting of a working group meeting, supervisor training, and optional coaching. Supervisors in the control departments received written information about the PA only. In two of the organizations, employees were invited to complete surveys at baseline and at 6-month follow-up. The primary outcome was perceived social norms regarding the use of the PA to deal with work functioning problems. Secondary measures included attitudes and self-efficacy, and intention regarding joint problem solving, and sick leave data. Effects were analyzed using multilevel analyses to account for nesting of cases. Results At baseline, 273 employees participated in the survey, with follow-up analyses of 174 employees. There were no statistically significant group effects on employee outcome measures. The intervention group showed a larger reduction in mean sick days (from 4.6 to 2.4 days) versus the control group (from 3.8 to 3.6 days), but this difference did not reach statistical significance (p > .05). Conclusion The multifaceted strategy to implement the participatory approach for supervisors did not show effects on outcomes at the employee level. To gain significant effects at the employee level, may require that an implementation strategy not only targets management and supervisors, but also employees themselves.

Implementation of the Participatory Approach for Supervisors to Increase Self-Efficacy in Addressing Risk of Sick Leave of Employees: Results of a Cluster-Randomized Controlled Trial.

Purpose To study the effectiveness of a multifaceted strategy to implement the participatory approach (PA) for supervisors to increase their self-efficacy in addressing risk of sick leave of employees. Methods Supervisors from three organizations were invited to participate. Randomization was performed at department level. Supervisors (n = 61) in the intervention departments received the implementation strategy consisting of a working group meeting, supervisor training in PA application, and optional supervisor coaching. Supervisors in the control departments (n = 55) received written information on PA. The primary outcome was supervisors' self-efficacy to apply the PA, measured at baseline and 6 months' follow-up. The number of employees with whom supervisors discussed work functioning problems or (risk of) sick leave was also assessed. Effects were tested using multilevel analyses. Results The strategy did not increase self-efficacy to apply the PA. Subgroup analyses showed that self-efficacy increased for supervisors who at baseline reported to have discussed (risk of) sick leave with less than three employees during the last 6 months (B = 1.42, 95 % CI 0.34-2.50). Furthermore, the implementation strategy increased the number of employees with whom supervisors discussed work functioning problems or risk of sick leave (B = 1.26, 95 % CI 0.04-2.48). Conclusion Although the implementation strategy cannot be recommended for all supervisors, for supervisors who less frequently discuss (risk of) sick leave with employees the implementation strategy might be helpful. Trial registration NTR3733.

Factors influencing work functioning after cancer diagnosis: a focus group study with cancer survivors and occupational health professionals.

PURPOSE: Cancer survivors (CSs) frequently return to work, but little is known about work functioning after return to work (RTW). We aimed to identify barriers and facilitators of work functioning among CSs. METHODS: Three focus groups were conducted with CSs (n = 6, n = 8 and n = 8) and one focus group with occupational health professionals (n = 7). Concepts were identified by thematic analysis, using the Cancer and Work model as theoretical framework to structure the results. RESULTS: Long-lasting symptoms (e.g. fatigue), poor adaptation, high work ethics, negative attitude to work, ambiguous communication, lack of support and changes in the work environment were mentioned as barriers of work functioning. In contrast, staying at work during treatment, open dialogue, high social support, appropriate work accommodations and high work autonomy facilitated work functioning. CONCLUSIONS: Not only cancer-related symptoms affect work functioning of CSs after RTW but also psychosocial and work-related factors. The barriers and facilitators of work functioning should be further investigated in studies with a longitudinal design to examine work functioning over time.

Employment and insurance outcomes and factors associated with employment among long-term thyroid cancer survivors: a population-based study from the PROFILES registry.

PURPOSE: To obtain insight into employment and insurance outcomes of thyroid cancer survivors and to examine the association between not having employment and other factors including quality of life. METHODS: In this cross-sectional population-based study, long-term thyroid cancer survivors from the Netherlands participated. Clinical data were collected from the cancer registry. Information on employment, insurance, socio-demographic characteristics, long-term side effects, and quality of life was collected with questionnaires. RESULTS: Of the 223 cancer survivors (response rate 87 %), 71 % were employed. Of the cancer survivors who tried to obtain insurance, 6 % reported problems with obtaining health care insurance, 62 % with life insurance, and 16 % with a mortgage. In a multivariate logistic regression analysis, higher age (OR 1.07, CI 1.02-1.11), higher level of fatigue (OR 1.07, CI 1.01-1.14), and lower educational level (OR 3.22, CI 1.46-7.09) were associated with not having employment. Employment was associated with higher quality of life. CONCLUSIONS: Many thyroid cancer survivors face problems when obtaining a life insurance, and older, fatigued, and lower educated thyroid cancer survivors may be at risk for not having employment.

Implementation of the participatory approach for supervisors to prevent sick leave: a process evaluation.

PURPOSE: To perform a process evaluation of a multifaceted strategy to implement the participatory approach for supervisors to prevent sick leave in three organisations. METHODS: The implementation strategy incorporated a working group meeting with stakeholder representatives, supervisor training, and optional supervisor coaching. Context, recruitment, reach, dose delivered, dose received, fidelity, and satisfaction with the strategy were assessed at organisational and supervisor level using questionnaires and registration forms. RESULTS: At least 4 out of 6 stakeholders were represented in the working group meetings, and 11 % (n = 116) of supervisors could be reached. The working group meetings and supervisor training were delivered and received as planned and were well appreciated within all three organisations. Three supervisors made use of coaching. At 6-month follow-up, 11 out of 41 supervisors (27 %) indicated that they had applied the participatory approach at least one time. CONCLUSION: The implementation strategy was largely carried out as intended. However, reach of both supervisors and department managers should be improved. Future studies should consider targeting employees with the strategy.

Multicentre validation of frequent sickness absence predictions.

BACKGROUND: A prediction model including age, self-rated health (SRH) and prior sickness absence (SA) has previously been found to predict frequent SA. AIMS: To further validate the model and develop it for clinical use. METHODS: A multicentre study of care of the elderly workers employed at one of 14 centres in Aarhus (Denmark). SA episodes recorded in the year prior to baseline and both age and SRH at baseline were included in a prediction model for frequent (three or more) SA episodes during a 1-year follow-up period. The prediction model was developed in the largest centre. Risk predictions and discrimination between high- and low-risk workers were investigated in the other centres. The prediction rule 'SRH-prior SA' was derived from the prediction model and prognostic properties of the prediction rule were investigated for each centre, using score <0 as cut-off. RESULTS: Of 2562 workers, 1930 had complete data for analysis. Predictions were accurate in 4 of 13 centres; discrimination was good in five and fair in another five centres. Prediction rule scores <0 identified workers at risk of frequent SA with sensitivities of 0.17-0.54, specificities of 0.86-0.96 and positive predictive values of 0.54-0.87 across centres. CONCLUSIONS: The prediction model discriminated between workers at high and low risk of frequent SA in the majority of centres. The prediction rule 'SRH-prior SA' can be used in clinical practice specifically to identify workers at high risk of frequent SA.

Fatigue as prognostic risk marker of mental sickness absence in white collar employees.

PURPOSE: To investigate fatigue as prognostic risk marker for identifying working employees at risk of long-term sickness absence (SA). METHODS: At baseline, fatigue was measured in 633 white collar employees with the checklist individual strength (CIS) including scales for fatigue severity, reduced concentration, reduced motivation, and reduced physical activity. SA was medically certified by an occupational physician in the 3rd or 4th SA week with diagnostic codes according to the 10th version of the International Classification of Diseases. Medically certified SA was retrieved at the individual level from an occupational health register after 1-year follow-up. CIS scores were investigated as prognostic risk markers predicting medically certified SA and particularly SA certified as mental SA. RESULTS: 614 employees (N = 378 men and N = 236 women) had complete data and were eligible for analysis; 63 (10 %) had medically certified SA of whom 39 (6 %) had mental SA. Fatigue severity and total CIS scores were associated with medically certified SA in men, but poorly discriminated between men with and without medically certified SA. Fatigue severity, reduced concentration, reduced motivation, and total CIS scores were also associated with mental SA in men. CIS and its reduced concentration scale were valid prognostic risk markers of mental SA. CONCLUSION Fatigue was a prognostic risk marker of mental SA in white collar men. The CIS should be further validated as a screening tool for the risk of mental SA in white collar working populations.

Sickness absence due to mental health disorders--a societal perspective.

BACKGROUND: Sickness absence (SA) is affected by societal factors. Increasing socioeconomic stress may cause or worsen mental health disorders, which are among the most frequent causes of SA. Employees may also be more cautious about being absent, for example in times of poor economy. AIMS: To monitor the incidence of SA due to mental health disorders in the Netherlands from 2001 to 2010. METHODS: Descriptive observational study of long-term (> 3 weeks) SA available from an occupational health service register. The incidence of both total and mental health long-term SA in each year was calculated and evaluated alongside the changes in SA compensation policies, gross national product and national unemployment statistics. The incidence of mental health SA was stratified based on the economic (agricultural, industrial, private, public) sector. RESULTS: The incidence of both total and mental health SA decreased gradually since 2004, and fell during the economic recession in 2009 in all economic sectors, particularly the agricultural and industrial sectors. The incidence of mental health SA increased with preliminary economic recovery in 2010 in the private and public sectors, but not in the agricultural and industrial sectors. CONCLUSIONS: Long-term SA due to mental health disorders has decreased since 2004, but further studies across countries are required to confirm and explain this trend.

Predicting return to work in workers with all-cause sickness absence greater than 4 weeks: a prospective cohort study.

INTRODUCTION: Long-term sickness absence is a major public health and economic problem. Evidence is lacking for factors that are associated with return to work (RTW) in sick-listed workers. The aim of this study is to examine factors associated with the duration until full RTW in workers sick-listed due to any cause for at least 4 weeks. METHODS: In this cohort study, health-related, personal and job-related factors were measured at entry into the study. Workers were followed until 1 year after the start of sickness absence to determine the duration until full RTW. Cox proportional hazards regression analyses were used to calculate hazard ratios (HR). RESULTS: Data were collected from N = 730 workers. During the first year after the start of sickness absence, 71% of the workers had full RTW, 9.1% was censored because they resigned, and 19.9% did not have full RTW. High physical job demands (HR .562, CI .348-.908), contact with medical specialists (HR .691, CI .560-.854), high physical symptoms (HR .744, CI .583-.950), moderate to severe depressive symptoms (HR .748, CI .569-.984) and older age (HR .776, CI .628-.958) were associated with a longer duration until RTW in sick-listed workers. CONCLUSIONS: Sick-listed workers with older age, moderate to severe depressive symptoms, high physical symptoms, high physical job demands and contact with medical specialists are at increased risk for a longer duration of sickness absence. OPs need to be aware of these factors to identify workers who will most likely benefit from an early intervention.

Employees sick-listed with mental disorders: who returns to work and when?

PURPOSE: To investigate return to work (RTW) in employees sick-listed with mental disorders classified according to the International Classification of Diseases (ICD). METHODS: Sickness absences (SA) medically certified as emotional disturbance (ICD-10 R45) or mental and behavioral disorders (ICD-10 F00-F99) were retrieved from an occupational health service register. RTW was associated with age, gender, and socioeconomic position (SEP) by parametric survival analysis. RESULTS: Emotional, neurotic, somatoform, stress-related, and mood disorders encompassed 94 % of all mental SA. Employees with emotional disturbance had the highest RTW rates: after 1 year 95 % had resumed work and after 2 years 98 % compared to 89 and 96 % of employees with neurotic, somatoform and stress-related disorders, and 70 and 86 % of employees with mood disorders. The probability of RTW decreased after 1 month of SA due to emotional disturbance, 2 months of SA with neurotic, somatoform and stress-related disorders, and 3 months of SA with mood disorders. Women resumed their work later than men. Young employees presenting with emotional disturbance, neurotic, somatoform, and stress-related disorders had earlier RTW than older employees and low-SEP employees had earlier RTW than high-SEP employees. CONCLUSIONS: RTW rates and probabilities differed across categories of mental disorders. Age and SEP were associated with RTW of employees with emotional, neurotic, somatoform, and stress-related disorders, but not with RTW of employees experiencing mood disorders. To maximize the likelihood of RTW, a focus on RTW is important in the first months after reporting sick with mental disorders.

Trends in return to work of breast cancer survivors.

Most women interrupt their work activities during the treatment of cancer. This study investigated return to work (RTW) after treatment of breast cancer in the period from January 2002 to December 2008. ArboNed Occupational Health Service records the sickness absence and RTW data of more than one million workers of whom approximately 40% are women. Incident cases of sickness absence due to breast cancer (ICD-10 code C50) were selected from the ArboNed register. Proportions of partial RTW, with 50% of the earnings before sickness absence, and full RTW were determined 1 year after diagnosis. Trends in partial RTW and full RTW were examined by Chi-square trend analysis. The time to partial RTW and full RTW was analysed by Cox regression and stratified by age (<40 years, 40-50 years and >50 years). The proportion of partial RTW was stable around 70% from 2002 to 2008. The proportion of full RTW decreased from 52% in 2002 to 43% in 2008 and showed a linear decline in women of all ages. The time to partial RTW and full RTW in the years 2003-2008 did not change significantly compared with 2002. In the Netherlands, the proportion of employed women who fully resumed working after breast cancer within 1 year of diagnosis has decreased since 2002. These results warrant more epidemiological research to examine the trends in RTW of breast cancer survivors across countries.
