Does Consulting an Occupational Medicine Specialist Decrease Time to Return to Work Among Total Knee Arthroplasty Patients? A 12-Month Prospective Multicenter Cohort Study.

PURPOSE: The aim of this study is to investigate whether total knee arthroplasty (TKA) patients who consulted an occupational medicine specialist (OMS) within 3 months after surgery, return to work (RTW) earlier than patients who did not consult an OMS. METHODS: A multi-center prospective cohort study was performed among working TKA patients, aged 18 to 65 years and intending to RTW. Time to RTW was analyzed using Kaplan Meier and Mann Whitney U (MWU), and multiple linear regression analysis was used to adjust for effect modification and confounding. RESULTS: One hundred and eighty-two (182) patients were included with a median age of 59 years [IQR 54-62], including 95 women (52%). Patients who consulted an OMS were less often self-employed but did not differ on other patient and work-related characteristics. TKA patients who consulted an OMS returned to work later than those who did not (median 78 versus 62 days, MWU p < 0.01). The effect of consulting an OMS on time to RTW was modified by patients' expectations in linear regression analysis (p = 0.05). A median decrease in time of 24 days was found in TKA patients with preoperative high expectations not consulting an OMS (p = 0.03), not in patients with low expectations. CONCLUSIONS: Consulting an OMS within 3 months after surgery did not result in a decrease in time to RTW in TKA patients. TKA patients with high expectations did RTW earlier without consulting an OMS. Intervention studies on how OMSs can positively influence a timely RTW, incorporating patients' preoperative expectations, are needed.

Do overweight/obesity and low levels of leisure-time vigorous physical activity moderate the effect of occupational physical activity on self-rated health of construction workers?

PURPOSE: To investigate the combined effects of occupational physical activity (OPA) and either overweight/obesity or low levels of leisure-time vigorous physical activity (LTVPA) on self-rated health. METHODS: A longitudinal study was performed among 29,987 construction workers with complete data on 2 Workers' Health Surveillance Programs during 2010-2018. Self-reported OPA involved strenuous work postures and manual material handling. Low level of LTVPA was defined as self-reported vigorous activity for less than three times per week lasting at least 20 min per session. Overweight and obesity were based on Body Mass Index (BMI) (25.0 ≤ BMI < 30.0 kg/m2 and BMI ≥ 30.0 kg/m2, respectively) using measured body height and weight. Self-rated health was measured using a single item question. Logistic regression analysis was used to investigate the associations between the separate risk factors at baseline and self-rated health at follow-up. The combined effects of demanding OPA and either overweight/obesity or low level of LTVPA on self-rated health were analyzed using the relative excess risk due to interaction (RERI). RESULTS: Mean follow-up duration was 31.7 (SD = 14.9) months. Construction workers with strenuous work postures (OR 1.35 95% CI 1.25-1.46), manual material handling (OR 1.29 95% CI 1.19-1.40), obesity (OR 1.31 95% CI 1.17-1.47) and low LTVPA (OR 1.13 95% CI 1.01-1.25) were more likely to report poor self-rated health at follow-up. No statistically significant interaction effects were found for OPA and obesity or low LTVPA. CONCLUSIONS: OPA, obesity and low level of LTVPA were separate risk factors for poor self-rated health, but did not appear to have a synergistic effect.

Use of a Decision Support Tool on Prognosis of Work Ability in Work Disability Assessments: An Experimental Study Among Insurance Physicians.

Purpose Assessment of prognosis of work disability is a challenging task for occupational health professionals. An evidence-based decision support tool, based on a prediction model, could aid professionals in the decision-making process. This study aimed to evaluate the efficacy of such a tool on Dutch insurance physicians' (IPs) prognosis of work ability and their prognostic confidence, and assess IPs' attitudes towards use of the tool. Methods We conducted an experimental study including six case vignettes among 29 IPs. For each vignette, IPs first specified their own prognosis of future work ability and prognostic confidence. Next, IPs were informed about the outcome of the prediction model and asked whether this changed their initial prognosis and prognostic confidence. Finally, respondents reported their attitude towards use of the tool in real practice. Results The concordance between IPs' prognosis and the outcome of the prediction model was low: IPs' prognosis was more positive in 72 (41%) and more negative in 20 (11%) cases. Using the decision support tool, IPs changed their prognosis in only 13% of the cases. IPs prognostic confidence decreased when prognosis was discordant, and remained unchanged when it was concordant. Concerning attitudes towards use, the wish to know more about the tool was considered as the main barrier. Conclusion The efficacy of the tool on IPs' prognosis of work ability and their prognostic confidence was low. Although the perceived barriers were overall limited, only a minority of the IPs indicated that they would be willing to use the tool in practice.

[A wider perspective on night work; health risks, lifestyle and interventions]. / Nachtwerk in breder perspectief.

A lot of research has been conducted into night work in recent years. This shows that people who work nights have an increased risk of type 2 diabetes and cardiovascular disease; people doing night work in the healthcare sector also have an increased risk of influenza and respiratory tract infections. There are also differences in sleep patterns, physical activity and diet between those who work at night and those who work during the day. However, at this point in time there are no effective lifestyle interventions available to lower the risks associated with night work. Along with the Health Council of the Netherlands we advise limiting night work as much as possible. Work is currently in progress on occupational medicine guidelines for night work.

Experiences with multiple job holding: a qualitative study among Dutch older workers.

BACKGROUND: Multiple job holding (MJH) is a common and growing phenomenon in many countries. Little is known about experiences with MJH among older workers. The objective of the present study is to gain insight in experiences with MJH among Dutch workers aged 45 years and older. METHODS: Multiple job holders were selected from the Study on Transitions in Employment, Ability, and Motivation (STREAM), a Dutch cohort study among persons aged 45 years and older. Purposive sampling was applied to assure heterogeneity regarding gender, educational level, health, financial situation, willingness to continue MJH, and type of MJH (only jobs as employee or also being self-employed). Interviews were conducted until data saturation occurred. Fifteen multiple job holders participated in this study (eight men, seven women). Interviews were digitally recorded, transcribed verbatim and analyzed, along with field notes, using thematic content analysis. The data were openly coded, after which codes were aggregated into themes, which formed a thematic map. In each phase of the analysis at least two researchers were involved to increase reliability. RESULTS: Experiences with MJH varied from positive to negative. They were influenced by characteristics of individual jobs, e.g. social support at work, as well as characteristics of the combination of jobs, e.g. positive spill-over effects, and conflicts between work schedules. The personal context of multiple job holders, e.g. their age, or reason for MJH, affected how work characteristics influenced experiences. Negative experiences with one job often coincided with negative experience in the other job(s), and problems in the personal context. Some multiple job holders were able to make changes to their situation when desired. For some, this was not possible, which augmented their negative experience. CONCLUSIONS: This study adds to existing knowledge that experiences with MJH are not only influenced by work characteristics but also by the personal context of multiple job holders, and that some workers are able to change their situation when desired, while others are not. Future research should study how different combinations of work and personal characteristics influence sustainable employability of multiple job holders. Policies facilitating life-long learning could increase opportunities to change the MJH situation when desired.

Predictors of fatigue and work ability in cancer survivors.

Background: Workers diagnosed with cancer are at risk for job loss or work disability. Aims: To determine predictors of fatigue and work ability at 36 months after diagnosis in a population of cancer survivors. Methods: Individuals diagnosed with cancer and who applied for work disability benefit at 24 months of sick leave were surveyed at the time of application and again 12 months later. Fatigue was measured using the Functional Assessment of Chronic Illness-Fatigue scale questionnaire and work ability was measured using the work ability index. Linear regression analyses were applied to identify predictors. Results: There were 336 participants. Participants who were divorced or widowed had more physical limitations, more depressive symptoms and were more fatigued at baseline, and who worked in health care demonstrated higher levels of fatigue. Lower fatigue was predicted by having received chemotherapy. A higher level of work ability was predicted by having received chemotherapy, better global health and better work ability at baseline. Lower work ability was predicted by being principal wage earner, insecurity about being free of disease, having more physical limitations and having greater wage loss. Conclusions: Socio-demographic, health- and work-related factors were associated with fatigue and work ability in cancer survivors on long-term sick leave. As fatigue and poor work ability are important risk factors for work disability, addressing the identified predictive factors may assist in mitigation of work disability in cancer survivors.

The cost-effectiveness and return-on-investment of a combined social and physical environmental intervention in office employees.

This study explored the cost-effectiveness and return-on-investment of a combined social and physical environmental worksite health promotion program compared with usual practice, and of both intervention conditions separately. Participants were randomized to the combined intervention (n = 92), social environmental intervention (n = 118), physical environmental intervention (n = 96), or control group (n = 106). The social environmental intervention consisted of group motivational interviewing and the physical environmental intervention of workplace modifications. Both interventions were aimed at improving physical activity and relaxation. Effects included need for recovery (NFR), general vitality and job satisfaction. Cost-effectiveness analyses were performed from the societal and employer's perspective, and return-on-investment analyses from the employer's perspective. Compared with usual practice, the combined intervention was significantly more effective in improving NFR (-8.4;95% CI:-14.6;-2.2) and significantly more expensive to the employer (3102; 95%CI:598;5969). All other between-group differences were non-significant. For NFR, the combined intervention became the preferred option at willingness-to-pays of ≥€170/point improvement (society) and ≥€300/point improvement (employer). For general vitality and job satisfaction, the interventions' maximum probabilities of cost-effective were low (≤0.55). All interventions had a negative return-on-investment. The combined intervention may be cost-effective for NFR depending on the decision-makers' willingness-to-pay. Both separate interventions are not cost-effective for NFR. All interventions were neither cost-effective for general vitality and job satisfaction, nor cost-saving to the employer.

Barriers and facilitators for return to work in cancer survivors with job loss experience: a focus group study.

Over 50% of cancer survivors lose their job or quit working. Cancer survivors who experience job loss may face different challenges regarding return to work, compared to cancer survivors with employers. This qualitative study aimed to explore barriers and facilitators for return to work in cancer survivors with job loss and in insurance physicians who assist cancer survivors in their return to work. We conducted five focus groups and one interview (cancer survivors, N = 17; insurance physicians, N = 23). Topics included, among others, experience of job loss and barriers and facilitators for return to work. Data were audio recorded and analysed using thematic analysis. Our main finding was that cancer survivors experienced a double loss: loss of job on top of loss of health. As a result, cancer survivors feared for job applications, lacked opportunities to gradually increase work ability, and faced reluctance from employers in hiring them. Insurance physicians expressed a need for more frequent and longer consultations with cancer survivors with job loss. We conclude that cancer survivors who experience double loss encounter specific barriers in the return to work process. This calls for a tailored approach regarding return to work support.

Therapeutic Work as a Facilitator for Return to Paid Work in Cancer Survivors.

Purpose The increase of flexible employment in European labour markets has contributed to workers' risk of job loss. For sick-listed workers with chronic illnesses, such as cancer, and especially those without an employment contract, participation in therapeutic work may be an important step towards paid employment. The purpose of this study was to determine the role of therapeutic employment as facilitator for return to paid work, in a cohort of sick-listed cancer survivors (CSs) with and without an employment contract. Methods In this longitudinal study, data were used from a cohort of Dutch CSs (N = 192), who applied for disability benefits after 2 years of sick leave. The primary outcome measure was return to paid work after 1 year. Logistic regression analysis was applied. Results Of the participating CSs (mean age 50.7 years, 33 % male), 69 % had an employment contract at baseline. CSs without an employment contract participated significantly less in therapeutic work (p < 0.001) and were less likely to return to paid work after 1 year (p = 0.001), than those with a contract. Participation in therapeutic work significantly increased the chance of return to paid work after 1 year (OR 6.97; 95 % CI 2.94-16.51), adjusted for age, gender, level of work disability and having an employment contract. Conclusions Participation in therapeutic work could be an important facilitator for return to paid work in sick-listed CSs. The effectiveness of therapeutic work as a means to return to paid employment for sick-listed workers should be studied in an experimental setting.

A behavioural approach in the development of work-related interventions for cancer survivors: an exploratory review.

The application of behavioural change models and theories has not been studied, and behavioural determinants have not been considered, in the context of cancer and work. The aim of this study is to assess the relevance of a behavioural approach in the development of work-related interventions for cancer survivors. Two search strategies were conducted to identify studies on (1) lifestyle interventions (exercise, smoking, alcohol intake and diet), based on behavioural models and theories, in cancer survivors; (2) behavioural determinants regarding work. Medline, Embase, PsycInfo, CINAHL and the Cochrane Controlled Trial Register were searched (2000-2015). Studies were assessed on their eligibility, and findings were listed and categorised. Thirty-four studies exploring lifestyle interventions in cancer survivors were retrieved. The behavioural change models and theories most regularly used were the Transtheoretical Model and Social Cognitive Theory. Furthermore, 26 studies on the role of behavioural determinants regarding work were found. The most frequently considered determinants were self-efficacy, social norms, workers' expectations towards work or recovery, attitude, motivation and meaning of work. The results indicate the significance of behavioural change models and theories and of behavioural determinants in related research areas, which encourages a behavioural approach in the development of work-related interventions for cancer survivors.

Limitations to Work-Related Functioning of People with Persistent "Medically Unexplained" Physical Symptoms: A Modified Delphi Study Among Physicians.

Purpose The purpose of this study was to obtain consensus among physicians of several medical specialties on the level of limitations to work-related functioning of people with persistent "medically unexplained" physical symptoms (PPS). Methods A modified Delphi study was conducted with 15 physicians of five different medical specialties. The study involved two email rounds and one meeting. In each round, the physicians prioritized the level of limitations in 78 work-related functioning items for four different PPS cases. These items were based on the Dutch Functional Ability List, national guidelines and scientific literature regarding the International Classification of Functioning. Results In all four cases, the physicians reached consensus on the level of limitations to work-related functioning in 49 items. The physicians reported the highest number and level of limitations for PPS of the back and lower extremities, but they reported hardly any limitations for PPS of the abdomen and genitals. For PPS of the head, they reported mainly limitations to personal and social functioning; for PPS of the neck, back and upper or lower extremities, they reported mainly limitations to dynamic movements and static postures. The physicians could not reach consensus on limitations in the category of working hours. Conclusion Physicians reached consensus on the level of limitations in a substantial part of work-related functioning items for PPS. There was a difference in the number and severity of limitations between different cases of PPS. The assessment of functioning seems to be based more on the specific impairment than on the disease.

Offering a tailored return to work program to cancer survivors with job loss: a process evaluation.

BACKGROUND: In Europe, 1.7 million persons of working age are diagnosed with cancer each year. During or after treatment, cancer survivors (CSs) are vulnerable for job loss, and many CSs struggle with return to work (RTW). When offering RTW interventions to CSs, it is important to conduct a process evaluation to assess such factors as the population reached and implementation problems. Recently, we developed an innovative RTW program, tailored specifically to the needs of CSs with job loss in the Netherlands. The aim of this study was to evaluate the likelihood of theory and implementation failure, as well as to evaluate procedures for recruitment, execution and implementation of the tailored RTW program for CSs with job loss. METHODS: Six components were evaluated in the RTW program: Recruitment, Reach, Dosage, Implementation, Satisfaction, and Experienced Barriers. Data were provided by logbooks and questionnaires from participating CSs, occupational health care (OHC) professionals, and re-integration coaches and job hunting officers who delivered the RTW program. SPSS and Excel were used to conduct the analyses. RESULTS: 85 CSs received the tailored RTW program. Their mean age was 47.9 years (SD 8.5). The majority were female (72 %), married (52 %), and of Dutch nationality (91 %). The program reached 88.2 % of the target population and 52 % of participants who started the program received the adequate dosage. The program implementation score was 45.9 %. Participants' mean overall program duration remained within the protocol boundaries. Re-integration coaches were more satisfied with the program than job hunting officers or OHC professionals. Likewise, participants were more satisfied with the program delivery by the re-integration coaches than with the delivery by the job hunting officers. Reported barriers within the RTW program were a lack of communication, high program intensity and short program duration, and, with regard to the job hunting officers, a lack of experience with cancer-related RTW problems. CONCLUSIONS: Participants, OHC professionals, re-integration coaches and job hunting officers generally had positive experiences with the innovative tailored RTW program. Facilitating communication between the delivering parties, and engaging usual care during program delivery, could be key elements to improved program implementation. TRIAL REGISTRATION: Dutch Trial Register, registration number NTR3562 , registered 07-08-2012.

Effectiveness of a tailored return to work program for cancer survivors with job loss: results of a randomized controlled trial.

BACKGROUND: Up to 53% of cancer survivors (CSs) experiences job loss during or after treatment. To support CSs with job loss in the Netherlands, a tailored return to work (RTW) program was developed. The objective of this study was to assess the effectiveness of the program on duration until sustainable RTW in CSs with job loss. MATERIAL AND METHODS: This study employed a two-armed (intervention/control) randomized controlled design with one-year follow-up. The primary outcome measure was duration until sustainable RTW. The secondary outcome measures were: rate of RTW, fatigue, quality of life, and participation in society. Descriptive analyses, Kaplan-Meier estimators and Cox regression analyses were conducted. RESULTS: Participants (N = 171) had a mean age of 48.4 years (SD = 8.6). The majority was female (69%) and breast cancer survivor (40%). The crude hazard ratio (HR) for duration until sustainable RTW was 0.86 (95% CI 0.46-1.62; p = 0.642). In the adjusted model, the intervention group had a slight, but statistically non-significant, improvement in duration until sustainable RTW compared to the control group (HR 1.16; 95% CI 0.59-2.31; p = 0.663). The program did not have any significant effects on secondary outcome measures. CONCLUSION: As the tailored RTW program did not demonstrate a statistically significant effect on duration until sustainable RTW in CSs with job loss, implementation of the program in its current form is not recommended.

Effectiveness of workplace interventions in the prevention of upper extremity musculoskeletal disorders and symptoms: an update of the evidence.

The burden of disabling musculoskeletal pain and injuries (musculoskeletal disorders, MSDs) arising from work-related causes in many workplaces remains substantial. There is little consensus on the most appropriate interventions for MSDs. Our objective was to update a systematic review of workplace-based interventions for preventing and managing upper extremity MSD (UEMSD). We followed a systematic review process developed by the Institute for Work & Health and an adapted best evidence synthesis. 6 electronic databases were searched (January 2008 until April 2013 inclusive) yielding 9909 non-duplicate references. 26 high-quality and medium-quality studies relevant to our research question were combined with 35 from the original review to synthesise the evidence on 30 different intervention categories. There was strong evidence for one intervention category, resistance training, leading to the recommendation: Implementing a workplace-based resistance training exercise programme can help prevent and manage UEMSD and symptoms. The synthesis also revealed moderate evidence for stretching programmes, mouse use feedback and forearm supports in preventing UEMSD or symptoms. There was also moderate evidence for no benefit for EMG biofeedback, job stress management training, and office workstation adjustment for UEMSD and symptoms. Messages are proposed for both these and other intervention categories.

Work disability assessment of cancer survivors: insurance physicians' perspectives.

BACKGROUND: Assessing work disability in cancer survivors is a complex decision-making process. In the Netherlands, physicians employed by the Dutch Social Security Agency (SSA) play a key role in assessing work disability of cancer survivors on long-term sick leave. AIMS: To investigate the aspects physicians consider in assessing work disability in cancer survivors, their experiences related to the use of guidelines and their needs related to the use of a prediction rule that aims to support work disability assessments. METHODS: A qualitative study involving three consecutive focus group interviews, using a predetermined topic list. The interviews were recorded, transcribed and independently analysed using standard procedures of thematic analysis. RESULTS: The 29 participating physicians reported feeling responsible primarily for making correct assessments of cancer survivors' work disability, in which they predominantly investigate medical factors. Secondarily, non-medical factors related to the person, their work and/or their social environment were considered. Adherence to guidelines aiming to support physicians making such assessments was variable. CONCLUSIONS: In assessing work disability among cancer survivors on long-term sick leave, physicians considered medical and non-medical factors. The relevance of non-medical factors became more prominent in cases where medical issues were less obvious. There seems to be a need to enhance adherence to guidelines in order to support the work disability assessment of cancer survivors. The development of an implementation strategy for a prediction rule to support the work disability assessment of cancer survivors should be considered.

Employees are ambivalent about health checks in the occupational setting.

BACKGROUND: Employees are increasingly provided with preventive health checks. However, participation rates are low and several ethical issues arise, such as a potential perceived threat to autonomy and privacy. AIMS: To assess what employees think about preventive health checks in the occupational setting. METHODS: Samples of construction workers and the general working population in the Netherlands completed a survey about preventive health checks in the occupational setting. We asked half of each sample about potential benefits and drawbacks of health checks, and the other half about how they should be offered. We employed explorative factor analysis to identify constructs related to perceived benefits and drawbacks, and the way health checks should be provided. We then conducted descriptive analyses and t-tests to compare subgroups of respondents. RESULTS: A total of 482 (27%) of construction workers and 738 (65%) employees from the general population responded. The overall survey response rate was 42% with 41% completing the first questionnaire and 42% the second. We identified three constructs related to perceived benefits and drawbacks: self-control over health, disturbance and negative emotion and lack of autonomy. Participants rated 'self-control over health' as the highest potential benefit (mean = 3.40; SD = 0.69), and 'your employer interfering in your personal life' as the most important potential drawback (mean = 3.27; SD = 1.00). Participants indicated that they would like to receive help from their occupational physician when an increased health risk is identified (mean = 4.02; SD = 0.69). CONCLUSIONS: Employees are ambivalent and hesitant concerning preventive health checks in the occupational setting.

Sickness absence and flight type exposure in flight crew members.

BACKGROUND: Shift work research has shown that the relationship between exposure to irregular working times and sickness absence may differ between working populations. Not much is known about the prevalence of sickness absence in flight crews or about the relationship between exposure to different flight schedules and sickness absence in this population. AIMS: To examine the association between cumulative exposure to different flight types and sickness absence in flight crew members. METHODS: The study population consisted of flight crew members from a 5 year historic cohort. Flight schedule and sickness absence data were obtained from company records. The association between the cumulative exposure to different flight types and sickness absence episodes of >7 days was determined using univariate and multivariate logistic regression analyses. Adjusted models were obtained by adding potential confounders. Previous sickness absence was added to compose the fully adjusted models. RESULTS: The records of 8228 employees were analysed. The fully adjusted univariate analyses showed that the numbers of medium-haul flights and flights with time zone crossings were associated with an increase in the odds for sickness absence. The fully adjusted multivariate analyses showed no significant associations between flight types and sickness absence. CONCLUSIONS: Cumulative exposure to flight types was not independently associated with sickness absence in flight crew members when previous sickness absence was taken into account. Because sickness absence in the past can predict future absence, preventive strategies targeted at flight crew members with a history of high sickness absence may be effective.

A qualitative study of the anticipated barriers and facilitators to the implementation of a lifestyle intervention in the Dutch construction industry.

BACKGROUND: Lifestyle interventions have proven effective for lowering a cardiovascular risk profile by improving lifestyle behaviors, blood glucose and blood cholesterol levels. However, implementation of lifestyle interventions is often met with barriers. This qualitative study sought to determine anticipated barriers and facilitators to the nationwide implementation of an effective lifestyle intervention in the construction industry in the Netherlands. METHODS: Prior to implementation, focus groups were held with 8 lifestyle counselors and semi-structured interviews with 20 employees of the construction industry, 4 occupational physicians, 4 medical assistants, and 1 manager of an occupational health service. The transcripts were coded by two coders and analyzed by constant comparison. RESULTS: Hypothetical employee willingness to sign up for the intervention was facilitated by a high level of perceived risk, perceived added value of the intervention, and perceived social support. It was hampered by a preference for independence and perceived interference with their work. All professionals named a lack of time as an anticipated barrier to implementation. Lifestyle counselors suggested several strategies to improve the proficiency of their counseling technique, such as training in small groups and a continuous stream of employee referrals. Occupational physicians thought they would be hampered in screening employees and referring them to a lifestyle counselor by the perception that addressing employee lifestyles was not their task, and by a counter-productive relationship with other stakeholders. The manager addressed financial incentives and a good intervention fit with the current approach of the OHS. CONCLUSION: The findings suggest that employees can be motivated to sign up for a lifestyle intervention by tailoring the implementation strategy to various subgroups within the target group. Occupational physicians can be motivated to refer employees for the intervention by making a referral personally and professionally rewarding.
