Pilot implementation of MiLES: a web-based intervention targeted at managers with the aim of enhancing the successful return to work of employees with cancer

BACKGROUND

MiLES is a web-based intervention targeted at managers with the aim of enhancing the successful return to work (RTW) of employees with cancer. The purpose of this study was to identify barriers to and facilitators of implementing MiLES in organizations, from a manager's perspective.

MATERIAL AND METHODS

MiLES was implemented as a pilot in four organizations for six weeks. Sixteen managers were included, of which fourteen were interviewed regarding their perceived barriers to and facilitators of implementation of MiLES in their organization. Interviews were recorded, transcribed verbatim and analyzed with content analysis.

RESULTS

The managers experienced barriers to and facilitators of implementation related to: (1) implementation responsibilities, (2) the intervention's content, and (3) organizational characteristics. Regarding implementation responsibilities, management board approval and an organizational infrastructure with distinct described implementation responsibilities were perceived as facilitators. Regarding the intervention's content, its accessibility, user-friendliness and completeness were perceived as facilitators. If the content did not meet the manager's specific needs, this was perceived as a barrier. Regarding organizational characteristics, several intangible (e.g., added value of MiLES within different organizations) and tangible (e.g., integration into absenteeism registration) organizational characteristics were perceived as facilitators. The absence of a quiet place to use MiLES was perceived as barrier.

CONCLUSION

Implementation of MiLES in organizations may benefit from an infrastructure within the organization that defines responsibilities regarding intervention delivery to managers of employees with cancer. Such an infrastructure should be aligned to existing organizational structures. As per interviewed managers, MiLES has added value in diverse organizations.

Interventions for work participation of unemployed or work-disabled cancer survivors: a systematic review

Background: Supporting unemployed or work-disabled cancer survivors in their work participation can have extensive individual and societal benefits. We aimed to identify and summarise interventions for work participation of unemployed or work-disabled cancer survivors.Methods: Five databases (Medline, Embase, PsycINFO, CINAHL and Cochrane Library) were systematically searched for quantitative studies on interventions aimed at enhancing work participation of unemployed or work-disabled cancer survivors. Work participation refers to participation in the workforce, fulfilling one's work role. Manual and automatic screening (with ASReview software) were performed on titles and abstracts, followed by manual full-text screening. Data were extracted regarding study, patient and intervention characteristics, and work participation outcomes. Risk of bias (RoB) was assessed using the Cochrane RoB2 and QUIPS tools.Results: We identified 10,771 articles, of which we included two randomised controlled trials (RCTs), of which one feasibility RCT, and three cohort studies. In total, 1862 cancer survivors were included, with predominantly breast cancer. Work participation was mainly measured as time to return to work (RTW) and RTW rate. Interventions included components of coaching (e.g., psychological or rehabilitation), training (e.g., building confidence and managing fatigue) and self-management. Two RCTs with unclear RoB did not show an effect of multicomponent interventions compared to care as usual. One cohort study found a significant effect of a psycho-educational intervention on RTW rates, with moderate RoB. The other two cohort studies, with moderate RoB, reported significant associations between components including job search and placement assistance, and work participation.Discussion: Only few interventions aimed at enhancing work participation of unemployed or work-disabled cancer survivors, have been evaluated. In two cohort studies, promising components for future multicomponent interventions were identified. However, findings suggest that more evidence is necessary on such multicomponent interventions, in which elements explicitly directed at work and including the workplace should be included.

A workers' health surveillance online training programme for occupational physicians

BACKGROUND

To support occupational physicians (OPs) in the implementation of workers' health surveillance (WHS), a training programme was developed.

AIMS

(i) To evaluate the effects of a WHS training programme for OPs on knowledge, self-efficacy and skills to implement WHS. (ii) To evaluate to what extent a WHS training programme is acceptable and feasible for implementation in practice.

METHODS

A single-blinded randomized controlled trial with waiting-list control group was used. The WHS training programme consisted of an e-learning and a 4.5-h online training session. OPs completed a knowledge test (0-8), self-efficacy questionnaires on knowledge and skills (6-60), and vignette assignments (0-16) to measure skills. OPs completed the questionnaires, either before and after the WHS training programme (intervention group), or before the training programme (control group) while receiving the training programme after the waiting period. All OPs completed questionnaires about the training's acceptability, and feasibility for implementation in practice. ANCOVA and Poisson regression analyses were conducted.

RESULTS

The self-efficacy score (M = 44.1 versus M = 37.2) (P < 0.001) and skills score (M = 9.6 versus M = 8.3) (P < 0.05) of OPs in the training group (N = 16) were higher than the control group (N = 23). No effect was found on knowledge. Evaluation of acceptability and feasibility showed that 21 (58%) OPs were very satisfied with the training part on initiating WHS, and 29 (85%) would recommend the WHS training programme to colleagues.

CONCLUSIONS

This WHS training programme has a positive effect on self-efficacy and skills of OPs to implement WHS, and may be acceptable and feasible to implement in practice.

Improving person-centered occupational health care for workers with chronic health conditions: a feasibility study

BACKGROUND

Person-centered care is needed to effectively support workers with chronic health conditions. Person-centered care aims to provide care tailored to an individual person's preferences, needs and values. To achieve this, a more active, supportive, and coaching role of occupational and insurance physicians is required. In previous research, two training programs and an e-learning training with accompanying tools that can be used in the context of person-centered occupational health care were developed to contribute to this changing role. The aim was to investigate the feasibility of the developed training programs and e-learning training to enhance the active, supportive, and coaching role of occupational and insurance physicians needed for person-centered occupational health care. Information about this is important to facilitate implementation of the tools and training into educational structures and occupational health practice.

METHODS

A qualitative study was conducted, with N = 29 semi-structured interviews with occupational physicians, insurance physicians, and representatives from occupational educational institutes. The aim was to elicit feasibility factors concerning the implementation, practicality and integration with regard to embedding the training programs and e-learning training in educational structures and the use of the tools and acquired knowledge and skills in occupational health care practice after following the trainings and e-learning training. Deductive analysis was conducted based on pre-selected focus areas for a feasibility study.

RESULTS

From an educational perspective, adapting the face-to-face training programs to online versions, good coordination with educational managers and train-the-trainer approaches were mentioned as facilitating factors for successful implementation. Participants underlined the importance of aligning the occupational physicians' and insurance physicians' competences with the educational content and attention for the costs concerning the facilitation of the trainings and e-learning training. From the professional perspective, factors concerning the content of the training and e-learning training, the use of actual cases from practice, as well as follow-up training sessions were reported. Professionals expressed good fit of the acquired skills into their consultation hour in practice.

CONCLUSION

The developed training programs, e-learning training and accompanying tools were perceived feasible in terms of implementation, practicality, and integration by occupational physicians, insurance physicians and educational institutes.

Identification of actions to be taken by managers to facilitate the return to work of cancer survivors: Consensus between managers and cancer survivors

Background

Managers are considered to be main stakeholders in the return to work (RTW) of cancer survivors. However, the perspectives of cancer survivors and managers differ on what managerial actions should be taken during the RTW of cancer survivors. This difference might put effective collaboration and successful RTW at risk. Therefore, this study aims to reach consensus among managers and cancer survivors on the managerial actions to be taken during the four different RTW phases of cancer survivors (i.e., Disclosure, Treatment, RTW plan, Actual RTW).

Methods

The Technique for Research of Information by Animation of a Group of Experts (TRIAGE) was implemented with managers and cancer survivors (hereafter referred to as “experts”). An initial list of 24 actions was derived from a previous study. Firstly, for each action, fifteen experts were asked to indicate individually how important this action is per RTW phase (Likert scale from 1 – “Not important at all” to 6 – “Very important”). Consensus was reached when ≥ 80% (i.e., ≥ twelve experts) of the experts rated that action ≥5. Secondly, for each phase of the RTW process, the 15 actions with the highest percentage were discussed with eight experts during the collective consultation, except for the actions that already reached consensus. After discussion, the experts voted whether each action was important (“yes” / “no”) and consensus required ≥ 87.5% (i.e., ≥ seven experts) of the experts to consider an action as important.

Results

Twenty-five managerial actions were finally retained for at least one of the RTW phases, e.g., Disclosure: “respect privacy” and “radiate a positive attitude”, Treatment: “show appreciation” and “allow sufficient sick leave”, RTW Plan: “tailor” and “communicate”, and Actual RTW: “support practically” and “balance interest”.

Conclusion

Cancer survivors and managers reached consensus on the importance of 25 managerial actions, distributed into each phase of the RTW process. These actions should be considered an interplay of managerial actions by different stakeholders on the part of the employer (e.g., direct supervisor, HR-manager), and should be a responsibility that is shared by these stakeholders. The collective implementation of these actions within the company will help cancer survivors feel fully supported.

Workers’ health surveillance targeting mental health: evaluation of a training

Background

Mental health complaints occur frequently among healthcare workers. A workers’ health surveillance mental health module (WHS-MH) was found to be effective in improving work functioning of nurses, although not implemented regularly. Therefore, training for occupational physicians and nurses to facilitate the implementation of WHS-MH was developed and evaluated.

Aims

This study was aimed to evaluate the effect of training on knowledge, self-efficacy and motivation to implement WHS-MH, and to evaluate participants’ satisfaction with the training.

Methods

Three-hour training was held among 49 occupational physicians and nurses in the Netherlands. Effect on knowledge, self-efficacy and motivation was assessed using knowledge tests and questionnaires before and immediately after the training. Satisfaction with the training was measured using questionnaires after the training.

Results

A mean knowledge test score of 5.3 (SD = 1.6) was found before training, which did not significantly increase after training (M = 5.6, SD = 1.8). In total, 43% agreed or strongly agreed to have sufficient skills to implement WHS-MH, which significantly increased to 78% after the training. Furthermore, 87% agreed or strongly agreed to be motivated to initiate WHS, which significantly increased to 94% after the training. The majority of participants were satisfied with the training.

Conclusions

Training may enhance the implementation of the WHS-MH through increasing self-efficacy and motivation. However, no effect on level of knowledge to implement WHS-MH was found.

A randomised feasibility trial of an employer-based intervention for enhancing successful return to work of cancer survivors (MiLES intervention)

BACKGROUND

Employers express a need for support during sickness absence and return to work (RTW) of cancer survivors. Therefore, a web-based intervention (MiLES) targeted at employers with the objective of enhancing cancer survivors' successful RTW has been developed. This study aimed to assess feasibility of a future definitive randomised controlled trial (RCT) on the effectiveness of the MiLES intervention. Also preliminary results on the effectiveness of the MiLES intervention were obtained.

METHODS

A randomised feasibility trial of 6 months was undertaken with cancer survivors aged 18-63 years, diagnosed with cancer < 2 years earlier, currently in paid employment, and sick-listed < 1 year. Participants were randomised to an intervention group, with their employer receiving the MiLES intervention, or to a waiting-list control group (2:1). Feasibility of a future definitive RCT was determined on the basis of predefined criteria related to method and protocol-related uncertainties (e.g. reach, retention, appropriateness). The primary effect measure (i.e. successful RTW) and secondary effect measures (e.g. quality of working life) were assessed at baseline and 3 and 6 months thereafter.

RESULTS

Thirty-five cancer survivors were included via medical specialists (4% of the initially invited group) and open invitations, and thereafter randomised to the intervention (n = 24) or control group (n = 11). Most participants were female (97%) with breast cancer (80%) and a permanent employment contract (94%). All predefined criteria for feasibility of a future definitive RCT were achieved, except that concerning the study's reach (90 participants). After 6 months, 92% of the intervention group and 100% of the control group returned to work (RR: 0.92, 95% CI: 0.81-1.03); no difference were found with regard to secondary effect measures.

CONCLUSIONS

With the current design a future definitive RCT on the effectiveness of the MiLES intervention on successful RTW of cancer survivors is not feasible, since recruitment of survivors fell short of the predefined minimum for feasibility. There was selection bias towards survivors at low risk of adverse work outcomes, which reduced generalisability of the outcomes. An alternative study design is needed to study effectiveness of the MiLES intervention.

TRIAL REGISTRATION

The study has been registered in the Dutch Trial Register ( NL6758/NTR7627 ).

Determinants for the implementation of person-centered tools for workers with chronic health conditions: a mixed-method study using the Tailored Implementation for Chronic Diseases checklist

BACKGROUND

The aim was to identify the most important determinants of practice for the implementation of person-centered tools which enhance work participation for patients with chronic health conditions.

METHODS

A mixed-method study was conducted consisting of semi-structured interviews, a focus group and a survey. Various stakeholders were involved including (representatives of) workers with chronic health conditions, insurance physicians, occupational physicians, other healthcare professionals, researchers, employers, and policymakers. The semi-structured interviews were performed to identify implementation determinants, followed by a focus group to validate resulting determinants. To conclude, a survey was conducted to select the most important implementation determinants through prioritization by ranking the order of importance. The Tailored Implementation of Chronic Diseases checklist (TICD) was used as concept-driven coding frame for the qualitative analysis of the interviews and focus group. The self-developed survey was based on the domains of the TICD. The survey was analyzed by frequency count of first ranking of determinants per and between domains of the TICD.

RESULTS

Various stakeholders participated (N = 27) in the interviews and focus group. The qualitative data retrieved yielded a list of determinants with additional in-depth themes according to the TICD. For the selection of the most important determinants, a survey with 101 respondents was conducted, consisting of occupational physicians, insurance physicians and workers with a chronic health condition. From the seven domains of the TICD, respondents emphasized the importance of taking into account the needs and factors associated with workers with a chronic health condition as this determinant ranked highest. Taking into account the individual needs and wishes of workers was mentioned to enable successful implementation, whereas stress of the workers was indicated to impede implementation. Other important determinants included 'being able to work with the tools' in terms of time and usability or 'cognitions, beliefs and attitudes of occupational and insurance physicians' to be able to use the tools.

CONCLUSION

This study identified the most important determinants from the perspective of various stakeholders involved in the implementation of client-centered tools in occupational health for workers with chronic health conditions. Furthermore, by prioritizing the most important determinants, targeted implementation strategies can be developed.

The Use and Perceived Usefulness of an Online Toolbox Targeted at Employers (MiLES Intervention) for Enhancing Successful Return to Work of Cancer Survivors

PURPOSE

The MiLES intervention is a web-based intervention targeted at employers with the objective of enhancing successful return to work (RTW) of cancer survivors. The aim of this study is to gain insight into the employers' use and perceived usefulness of the MiLES intervention.

METHODS

Employer representatives (e.g. Human Resource managers and supervisors) were given access to the MiLES intervention, which contains, among others, interactive videos, conversation checklists and tailored tips. After six weeks, an online questionnaire gathered data on employers' use and the perceived usefulness of the intervention. In-depth qualitative data on these topics were gathered during semi-structured interviews, which were analyzed using a content analysis.

RESULTS

Thirty-one eligible employers were included. Twenty-two of them filled out the questionnaire and twenty were interviewed. Typically, employers used the intervention 2-3 times, for 26 min per visit. The usefulness of the intervention scored 7.6 out of 10 points, and all employers would recommend it to colleagues. Employers' use decreased when support needs were low and when the intervention did not correspond with their specific situation (e.g. complex reintegration trajectories). Employers perceived the intervention to be supporting and practically oriented. They appreciated the fact that the intervention was web-based and combined visual and textual content. The possibility of consulting specialized services for complex situations would further enhance its usefulness.

CONCLUSION

The MiLES intervention provides employers with a useful tool in their daily practice. Its effectiveness for enhancing employers' managerial skills and cancer survivors' successful RTW is subject for further research.

Effectiveness of a Tailored Work-Related Support Intervention for Patients Diagnosed with Gastrointestinal Cancer: A Multicenter Randomized Controlled Trial

Purpose The aim of this research was to study the effectiveness on return to work (RTW) of an early tailored work-related support intervention in patients diagnosed with curative gastrointestinal cancer. Methods A multicenter randomized controlled trial was undertaken, in which patients were assigned randomly to the intervention or the control group (usual care). The intervention encompassed three psychosocial work-related support meetings, starting before treatment. Five self-reported questionnaires were sent over twelve months of follow-up. Primary outcome was days until RTW (fulltime or partial) and secondary outcomes included work status, quality of life, work ability, and work limitations. Descriptive analysis, Kaplan-Meier analysis, relative risk ratio and linear mixed models were applied. Results Participants (N = 88) had a mean age of 55 years; 67% were male and the most common cancer type was colon cancer (66%). Of the participants, 42 were randomized to the intervention group. The median time from sick leave until RTW was 233 days (range 187-279 days) for the control group, versus 190 days (range 139-240 days) for the intervention group (log-rank p = 0.37). The RTW rate at twelve months after baseline was 83.3% for the intervention group and 73.5% for the control group. Work limitations did statistically differ between the groups over time (p = 0.01), but quality of life and work ability did not. Conclusion Patients in the intervention group seem to take fewer days to RTW, albeit not to a statistically significant extent.Trial registration Trial NL4920 (NTR5022) (Dutch Trial Register https://www.trialregister.nl ).

Supporting employers to enhance the return to work of cancer survivors: development of a web-based intervention (MiLES intervention)

Purpose

The purpose of this study was to develop an intervention targeting employers, with the aim of enhancing cancer survivors’ return to work (RTW).

Methods

Intervention Mapping was used to combine information gathered from several procedures involving numerous stakeholders, for example, employers, cancer survivors, oncological occupational physicians, and e-health experts.

Results

Employers indicated that they require tailored support during four RTW phases: (1) disclosure, (2) treatment, (3) RTW planning, and (4) actual RTW. The most important employer actions were identified for each RTW phase, for instance, “communicate,” “support practically,” and “assess work ability,” and thereafter formulated as the performance objectives of the intervention. The trans-theoretical model of change was used as a theoretical framework, and several methodologies were employed to induce the desired behavior change, for example modeling, tailoring, and active learning. Subsequently, a web-based intervention with interactive videos, conversation checklists, links to reliable external sources, and succinct, tailored tips and information was developed and adjusted on the basis of pre-tests with different stakeholders.

Conclusions

The intervention was developed with input from employers and all relevant stakeholders in the RTW of cancer survivors. The systematic, step-wise development resulted in a succinct and easily accessible intervention targeting the most important employer actions during all RTW phases. As such, the intervention corresponds with employers’ needs and preferences in practice.

Implications for cancer survivors

By providing employers with support, the intervention could well be the missing link in efforts to optimize the work participation of cancer survivors.

Two-Year Follow-Up of a Multi-centre Randomized Controlled Trial to Study Effectiveness of a Hospital-Based Work Support Intervention for Cancer Patients

Purpose Purpose is to: (1) study effectiveness of the hospital-based work support intervention for cancer patients at two years of follow-up compared to usual care and (2) identify which early factors predict time to return-to-work (RTW). Methods In this multi-center randomised controlled trial (RCT), 106 (self-)employed cancer patients were randomized to an intervention group or control group and provided 2 years of follow-up data. The intervention group received patient education and work-related support at the hospital. Primary outcome was RTW (rate and time) and quality of life (SF-36), and secondary outcomes were, work ability (WAI), and work functioning (WLQ). Univariate Cox regression analyses were performed to study which early factors predict time to full RTW. Results Participants were diagnosed with breast (61%), gynaecological cancer (35%), or other type of cancer (4%). RTW rates were 84% and 90% for intervention versus control group. They were high compared to national register-based studies. No differences between groups were found on any of the outcomes. Receiving chemotherapy (HR = 2.43, 95% CI 1.59-3.73 p < 0.001), low level of education (HR = 1.65, 95% CI 1.076-2.52 p = 0.02) and low work ability (HR = 1.09 [95% CI 1.04-1.17] p = 0.02) were associated with longer time to full RTW. Conclusions We found high RTW rates compared to national register-based studies and we found no differences between groups. Future studies should therefore focus on reaching the group at risk, which consist of patients who receive chemotherapy, have a low level of education and have a low work ability at diagnosis.

What Employer Actions Are Considered Most Important for the Return to Work of Employees with Cancer? A Delphi Study Among Employees and Employers

Purpose Employers are important stakeholders in the return to work (RTW) of employees with cancer. However, it is unclear what employer actions are most important to that process. The objective, therefore, was to reach consensus on what employer actions are considered most important for the RTW of employees with cancer, by employers and employees separately. Methods A two-round online Delphi study was conducted with two expert panels: one with 23 employers and one with 29 employees with cancer. The results from each panel were analysed separately. Out of 24 suggested employer actions, participants selected the 10 they considered most important for RTW in each of the following RTW phases: (1) disclosure, (2) treatment, (3) RTW plan, and (4) actual RTW. The consensus threshold was set at ≥ 80% during the second round. Results The employer and employee expert panels both reached consensus on the importance of 'emotional support', 'practical support', 'allow sufficient sick leave', 'plan return to work', 'adjust expectations', 'assess work ability', and 'show appreciation'. Employers also reached consensus on 'communicate' and 'treat normally', and employees on 'handle unpredictability'. All these employer actions were considered to be specific for one to three RTW phases. Conclusions Employers reached consensus on the importance of nine employer actions, employees on eight. Both stakeholder perspectives showed great similarities, but did vary regarding important employer actions during the employee's treatment. We recommend developing interventions targeting the employer, meeting both employer and employee needs in each RTW phase, to enhance RTW support for employees with cancer.

Higher incidence of screening-related cancers in the employed population

Background

Employment may confound the risk of a cancer diagnosis in both directions. We hypothesized that a higher baseline rate of employment among cancer patients may explain the lack of association between a cancer diagnosis and later unemployment in many studies.

Aims

To assess the unemployment rate among cancer patients before diagnosis compared with a matched cancer-free control group.

Methods

Using data from the Israeli National Central Bureau of Statistics 1995 census (persons aged between 15 and 60 years old), the Israeli Tax Authority database and the Israel Cancer Registry, cancer patients (diagnosed between the years 2000 and 2007 and alive at 2011) were compared with matched cancer-free controls.

Results

There were 8797 cancer patients and 26166 cancer-free controls. We found that, in general, cancer was not associated with unemployment 2 years before diagnosis (adjusted odds ratio [OR] = 0.96, 95% confidence interval [CI] 0.90-1.009, P = NS) after adjustment for age, gender, ethnicity, educational years and residential socioeconomic position. However, the diagnoses associated with screening (breast, prostate, colorectal and cervix cancers) were inversely associated with unemployment 2 years before diagnosis (adjusted OR = 0.90, 95% CI 0.84-0.97, P < 0.01).

Conclusions

The results from the current study suggest that a higher baseline rate of employment among cancer patients, mainly those who were diagnosed with screening-associated cancers, explains false negative results in previous studies assessing cancer survivors' work issues.

Cancer and its impact on work among the self-employed: A need to bridge the knowledge gap

Self-employment-the so-called flexible layer of the economy-has gained importance following the 2007-2008 global economic and financial crisis. In Europe, the self-employed now comprise on average 15% of workers [Eurostat, Labour market and Labour force survey (LFS) statistics, 2016]. Around one-third of self-employed people also provide jobs for others [European Commission, Fact Sheet. 2015 Employment and Social Developments in Europe Review: frequently asked questions, 2016]. Moreover, this group of workers adapts quickly to changing circumstances. In the UK, for instance, recent growth in self-employment is considered to have made an important contribution to labour market recovery [Hatfield, Self-employment in Europe. London, Institute of Public Policy Research, 2015]. Across the European Union self-employment is viewed as a key enabler of sustainable economic growth and, reflecting this, the Europe 2020 strategy encourages member states both to promote self-employment and to remove measures that discourage it [Library of the European Parliament, Self-employment and social security. Effects on innovation and economic growth, 2013].

Employment and social benefits up to 10 years after breast cancer diagnosis: a population-based study

Background:

Little is known about employment outcomes after breast cancer (BC) beyond the first years after treatment.

Methods:

Employment outcomes were compared with a general population comparison group (N=91 593) up to 10 years after BC for 26 120 patients, diagnosed before age 55 between 2000–2005, with income and social benefits data from Statistics Netherlands. Treatment effects were studied in 14 916 patients, with information on BC recurrences and new cancer events.

Results:

BC survivors experienced higher risk of losing paid employment (Hazard Ratio (HR): 1.6, 95% Confidence Interval (95% CI) 1.4–1.8) or any work-related event up to 5–7 years (HR 1.5, 95% CI 1.3–1.6) and of receiving disability benefits up to 10 years after diagnosis (HR 2.0, 95% CI 1.6–2.5), with higher risks for younger patients. Axillary lymph node dissection increased risk of disability benefits (HR 1.5, 95% CI 1.4–1.7) or losing paid employment (HR 1.3, 95% CI 1.2–1.5) during the first 5 years of follow-up. Risk of disability benefits was increased among patients receiving mastectomy and radiotherapy (HR 1.2; 95% CI 1.1–1.3) and after chemotherapy (HR 1.7; 95% CI 1.5–1.9) during the first 5 years after diagnosis.

Conclusions:

BC treatment at least partly explains the increased risk of adverse employment outcomes up to 10 years after BC.

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.

Supporting cancer patients with work-related problems through an oncological occupational physician: a feasibility study

To evaluate the feasibility of an oncological occupational physician (OOP) who is trained in oncological work-related problems, and in providing work-related support to cancer patients within the curative setting. We assessed facilitators and barriers that affect the activities of an OOP, and the satisfaction of the OOPs and patients with this new form of health care. Interviews were held with (1) OOPs (N = 13) to assess facilitators, barriers and their satisfaction with their ability to give supportive care and (2) cancer patients (N = 8) to assess their satisfaction concerning consulting an OOP. The main facilitators were positive feedback from health care providers and patients about the received care and support that the OOP had given, and the additional knowledge of the OOPs about cancer and work-related problems. Major barriers for being active as an OOP were lack of financial support for the OOP and the unfamiliarity of patients and health care providers with the specialised occupational physician. Both OOPs and the specialised knowledge and additional training of the OOPs facilitated providing support to cancer patients and survivors with work-related problems. Familiarity with the specialised occupational physician and financial support should be improved.

A hospital-based work support intervention to enhance the return to work of cancer patients: a process evaluation

PURPOSE

To perform a process evaluation of a hospital-based work support intervention for cancer patients aimed at enhancing return to work and quality of life. The intervention involves the delivery of patient education and support at the hospital and involves the improvement of the communication between the treating physician and the occupational physician. In addition, the research team asked patient's occupational physician to organise a meeting with the patient and the supervisor to make a concrete gradual return-to-work plan.

METHODS

Eligible were cancer patients treated with curative intent and who have paid work. Data were collected from patients assigned to the intervention group (N = 65) and from nurses who delivered the patient education and support at the hospital (N = 4) by means of questionnaires, nurses' reports, and checklists. Data were quantitatively and qualitatively analysed.

RESULTS

A total of 47 % of all eligible patients participated. Nurses delivered the patient education and support in 85 % of the cases according to the protocol. In 100 % of the cases at least one letter was sent to the occupational physician. In 10 % of the cases the meeting with the patient, the occupational physician and the supervisor took place. Patients found the intervention in general very useful and nurses found the intervention feasible to deliver.

CONCLUSIONS

We found that a hospital- based work support intervention was easily accepted in usual psycho-oncological care but that it proved difficult to involve the occupational physician. Patients were highly satisfied and nurses found the intervention feasible.

Work-related upper extremity disorders: one-year follow-up in an occupational diseases registry

Purpose

To study the course and consequences of work-related upper extremity disorders in the registry of the Netherlands Centre for Occupational Diseases (NCvB).

Methods

A follow-up study was performed in a sample of consecutive cases of work-related upper extremity disorders notified to the NCvB. Perceived severity was measured with VAS (0-100), quality of life with VAS (0-100) and SF-36, functional impairment with DASH and sickness absence with a questionnaire. Measurements took place directly after notification (T0) and after 3, 6 and 12 months (T1-T3). A linear mixed model was used to compare scores over time.

Results

Average age of the 48 consecutive patients (89% response) was 42 years; 48% were men. Perceived severity, functional impairment and sickness absence decreased statistically significant during the follow-up period, and quality of life scores improved. Patients older than 45 years scored worse on perceived severity of the disease, functional impairment and quality of life than did younger patients.

Conclusions

The role of registries of occupational diseases for preventive policy can be extended by creating longitudinal data in sample projects. In the sample from our registry, work-related upper extremity disorders had a favourable course.

Employment status and work-related problems of gastrointestinal cancer patients at diagnosis: a cross-sectional study

Objective To assess the employment status of patients with gastrointestinal cancer at diagnosis and to examine work-related problems of employed patients. Design New, consecutive patients were included at the Gastrointestinal Oncology Center Amsterdam, a one-stop, rapid access diagnostic assessment centre. Patients were interviewed on their employment status by a nurse. If (self-) employed, patients were asked to self-report on work-related problems, perceived distress (0-10), cancer-related problems, fatigue (MFI-20, range 4-20) and work ability (three WAI questions, range 0-10). Results Of all 333 included new consecutive patients (age range 32-89 years), 95 patients (28%) were (self-) employed at time of diagnosis, 179 (54%) were pensioners, and 59 were not working (18%). For the assessment of work-related problems, 45 (47%) of these 95 employed patients with cancer participated. Their mean age was 56 years, and patients had oesophageal/stomach (49%), colorectal (18%) or hepatic/pancreatic/biliary cancer (33%). Half of the employed patients (49%) were still at work, while 51% were on sick leave. The main reasons for sick leave were stress (35%), (scheduled) operation (26%), fatigue (17%) and pain (13%). Most patients on sick leave (70%) had no contact with their own occupational physician, although the majority (67%) would like to continue to work. Work-related problems were experienced by 73% of working patients. The mean work ability was 5.4, the mean general fatigue score was 11.5, and the mean distress score was 4.7. Employed patients on sick leave reported a lower work ability, more fatigue and higher distress but no more cancer-related problems compared with those still working. Conclusion A quarter of all patients with gastrointestinal cancer seen at an oncological centre are employed at time of diagnosis, and of these employed patients, 73% experience work-related problems. During diagnosis and treatment, information and support on work-related issues should be offered to patients with cancer as an essential part of high-quality oncological care.

Fatigue and its correlates in cancer patients who had returned to work--a cohort study

OBJECTIVES

Fatigue and other symptoms in cancer patients often interfere with social and occupational activities. Only a few studies, however, have examined relationship between fatigue and work-related outcomes. The aim of this study was to investigate which disease-related factors (treatment, diagnosis, cognitive dysfunction, depression, pain, and sleep disturbance) and work-related factors (work-load, work pressure, relationship to supervisor and colleagues, size of the company, and workplace accommodations) were related to fatigue in employed cancer survivors.

METHODS

Data was collected by questionnaire at 6 months (baseline) and 18 months (end of the follow-up) after cancer diagnosis from 135 people with different types of cancer who had returned to work at follow-up. Fatigue was measured with a four-item sub-scale of MFI. Scores ranged from 4 to 20, with higher scores indicating more fatigue.

RESULTS

The mean rate of general fatigue was 11.9 at baseline decreasing to 10.4 at the end of the follow-up (p<0.0001). At 6 months, higher work pressure (p = 0.02), physical workload (p<0.05) and less workplace accommodations (p = 0.03) were related to higher levels of fatigue. From disease-related factors, depression was associated with fatigue (p<0.0001) at baseline. Lack of workplace accommodations was the only factor affecting higher levels of fatigue at 18 months (p<0.001) and was also related to higher levels of depression at 6 months (p = 0.02) and at 18 months (p<0.001).

CONCLUSIONS

Lack of workplace accommodations was significantly related to fatigue at the end of the follow-up, which suggests that accommodations for illness can help to reduce fatigue and depression.

Factors that promote or hinder young disabled people in work participation: a systematic review

INTRODUCTION

The aim of this systematic review was to study factors which promote or hinder young disabled people entering the labor market.

METHODS

We systematically searched PubMed (by means of MESH and text words), EMBASE, PsycINFO, Web of Science and CINAHL for studies regarding (1) disabled patients diagnosed before the age of 18 years and (2) factors of work participation.

RESULTS

Out of 1,268 retrieved studies and 28 extended studies from references and four from experts, ten articles were included. Promoting factors are male gender, high educational level, age at survey, low depression scores, high dispositional optimism and high psychosocial functioning. Female and low educational level gives high odds of unemployment just like low IQ, inpatient treatment during follow up, epilepsy, motor impairment, wheelchair dependency, functional limitations, co-morbidity, physical disability and chronic health conditions combined with mental retardation. High dose cranial radiotherapy, type of cancer, and age of diagnosis also interfered with employment.

CONCLUSIONS

Of the promoting factors, education appeared to be important, and several physical obstructions were found to be hindering factors. The last mentioned factors can be influenced in contrast to for instance age and gender. However, to optimize work participation of this group of young disabled it is important to know the promoting or hindering influence for employment.

Determinants of work ability and its predictive value for disability

BACKGROUND

Maintaining the ability of workers to cope with physical and psychosocial demands at work becomes increasingly important in prolonging working life.

AIMS

To analyse the effects of work-related factors and individual characteristics on work ability and to determine the predictive value of work ability on receiving a work-related disability pension.

METHODS

A longitudinal study was conducted among 850 construction workers aged 40 years and older, with average follow-up period of 23 months. Disability was defined as receiving a disability pension, granted to workers unable to continue working in their regular job. Work ability was assessed using the work ability index (WAI). Associations between work-related factors and individual characteristics with work ability at baseline were evaluated using linear regression analysis, and Cox regression analysis was used to evaluate the predictive value of work ability for disability.

RESULTS

Work-related factors were associated with a lower work ability at baseline, but had little prognostic value for disability during follow-up. The hazard ratios for disability among workers with a moderate and poor work ability at baseline were 8 and 32, respectively. All separate scales in the WAI had predictive power for future disability with the highest influence of current work ability in relation to job demands and lowest influence of diseases diagnosed by a physician.

CONCLUSION

A moderate or poor work ability was highly predictive for receiving a disability pension. Preventive measures should facilitate a good balance between work performance and health in order to prevent quitting labour participation.

Doppler ultrasound surveillance in deep tunneling compressed-air work with Trimix breathing: bounce dive technique compared to saturation-excursion technique

The Western Scheldt Tunneling Project in The Netherlands provided a unique opportunity to evaluate two deep-diving techniques with Doppler ultrasound surveillance. Divers used the bounce diving techniques for repair and maintenance of the TBM. The tunnel boring machine jammed at its deepest depth. As a result the work time was not sufficient. The saturation diving technique was developed and permitted longer work time at great depth. Thirty-one divers were involved in this project. Twenty-three divers were examined using Doppler ultrasound. Data analysis addressed 52 exposures to Trimix at 4.6-4.8 bar gauge using the bounce technique and 354 exposures to Trimix at 4.0-6.9 bar gauge on saturation excursions. No decompression incidents occurred with either technique during the described phase of the project. Doppler ultrasound revealed that the bubble loads assessed in both techniques were generally low. We find out, that despite longer working hours, shorter decompression times and larger physical workloads, the saturation-excursion technique was associated with significant lower bubble grades than in the bounce technique using Doppler Ultrasound. We conclude that the saturation-excursion technique with Trimix is a good option for deep and long exposures in caisson work. The Doppler technique proved valuable, and it should be incorporated in future compressed-air work.

Sentinel surveillance of occupational diseases: a quality improvement project

BACKGROUND

Occupational diseases are generally underreported. The aim of this study was to evaluate whether a sentinel surveillance project comprising motivated and guided occupational physicians would provide higher quality information than a national registry for a policy to prevent occupational diseases.

METHODS

A group of 45 occupational physicians participated in a sentinel surveillance project for two years. All other occupational physicians (N = 1,729) in the national registry were the reference group. We compared the number of notifications per occupational physician, the proportion of incorrect notifications, and the overall reported incidence of occupational diseases.

RESULTS

The median number of notifications per occupational physician during the project was 13.0 (IQR, 4.5-31.5) in the sentinel group versus 1.0 (IQR, 0.0-5.0) in the reference group (P < 0.001). The proportion of incorrect notifications was 3.3% in the sentinel group and 8.9% in the reference group (P < 0.001). The overall reported occupational disease incidence was 7 times higher (RR = 6.9, 95% CI: 6.5-7.4) in the sentinel group (466 notifications per 100,000 employee years) than in the reference group (67 notifications per 100,000 employee years).

CONCLUSIONS

A sentinel surveillance group comprising motivated and guided occupational physicians reported a substantially higher occupational disease incidence and a lower proportion of incorrect notifications than a national registry.

The effect of individual counselling and education on work ability and disability pension: a prospective intervention study in the construction industry

OBJECTIVES

To investigate the effectiveness of a counselling and education programme on work ability and work disability pension for employees in the construction industry.

METHODS

Employees with a high disability risk of 38% or more in the following four years were included. Employees in the intervention group were either selected by an occupational physician or enrolled themselves. They received an assessment and individual programme focused on optimising work functioning, while the control group received care-as-usual. Data on work ability measured with the Work Ability Index (WAI) and work disability pensions were collected at baseline during a periodic occupational health examination and at 9, 18 and 26 months after the start of the intervention using a questionnaire.

RESULTS

Most employees in both the intervention (n = 83) and control group (n = 209) were carpenters (43% and 37%) and bricklayers (7% and 15%). In the intervention group, 42% successfully completed the programme. Work ability in the intervention group was lower at baseline but showed an increase over time while work ability of the control group remained the same. The work ability in the intervention group improved slightly more (p = 0.09). No statistically significant differences in percentages of employees receiving a disability pension between the intervention and control group were found at 9 or 18 months and no differences in the age-adjusted percentages of employees receiving a disability pension were found between the groups at any measurement.

CONCLUSIONS

The programme was slightly effective in improving the work ability but not in reducing work disability pensions. A more comprehensive multidisciplinary intervention programme might be necessary.

Effects of prolonged intensive care unit stay on quality of life and long-term survival after transthoracic esophageal resection

OBJECTIVE

There are few prospective data on the effects of prolonged intensive care unit stay on the quality of life and long-term survival of a homogeneous patient population. Therefore, the aims of this prospective study were a) to describe the quality of life in patients after having a transthoracic esophageal resection; and b) to analyze the influences of a prolonged intensive care unit stay on quality of life and survival in patients after esophageal cancer resection who survived to hospital discharge.

DESIGN

Prospective study.

SETTING

Medical center.

PATIENTS

The study population consisted of 109 patients undergoing a transthoracic resection for adenocarcinoma of the middistal esophagus or gastric cardia between April 1994 and February 2000.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A comparison was made between patients staying <or=5 days vs. >or=6 days in the intensive care unit and also <or=2 days vs. >or=14 days. Quality of life was assessed in all patients by mailed self-report questionnaires at baseline (preoperatively), at 5 wks, and at 3, 6, 9, 12, 18, 24, 30, and 36 months after surgery. Daily physical, emotional, and social functioning was assessed with the generic Medical Outcome Studies Short Form-20. Disease-specific quality of life was measured by an adapted Rotterdam Symptom Check List. Quality of life data were gathered between July 1994 and March 2003. Five of the 109 patients died in the hospital and were excluded from the analysis. All five of them were in the intensive care unit >or=6 days. Of the remaining 104 patients, 92 provided baseline scores. The data of the 92 patients were used for the quality of life analyses. For the clinicopathologic and survival analysis, the data of 104 hospital survivors were used. Patients spent a median of 5.5 days (range 0-71) in the intensive care unit. The Medical Outcome Studies Short Form-20 and the Rotterdam Symptom Check List measurements showed no clear differences in long-term quality of life between patients after a short vs. a prolonged postoperative intensive care unit period. The median overall survival in all patients was 2.0 yrs (range 0.1-8.0). Median overall survival in patients staying in the intensive care unit <or=5 days was 1.9 yrs (range 0.3-7.4 yrs) vs. 2.7 yrs (range 0.9-7.2 yrs) in patients staying >or=6 days (p = .9, log-rank test). Median overall survival in patients staying in the intensive care unit <or=2 days was 1.7 yrs (range 1.2-2.6 yrs) vs. 2.0 yrs (range 0.2-3.8 yrs) in patients staying >or=14 days (p = .74, log-rank test).

CONCLUSIONS

For patients who survived to hospital discharge after transthoracic esophagectomy, there was no difference in long-term quality of life or survival between those submitted to the intensive care unit for a short period vs. a long period.

An occupational health intervention programme for workers at risk for early retirement; a randomised controlled trial

AIMS

To evaluate an occupational health intervention programme for workers at risk for early retirement.

METHODS

Between April 1997 and May 1998, 116 employees of a large company who were older than 50 years indicated that they would not be able to work up to their retirement. They were randomly assigned to an intervention (n = 61) or control group (n = 55). The intervention programme lasted six months and was executed by an occupational physician. Job position and number of sick leave days after two years were collected from the company's computer database. A questionnaire was sent to the employees at baseline, after six months, and after two years; it included the Work Ability Index, the Utrecht Burn Out Scale, and the Nottingham Health Profile measuring quality of life.

RESULTS

Fewer employees (11%) in the intervention group retired early than in the control group (28%). The total average number of sick leave days in two years was 82.3 for the intervention group and 107.8 for the control group. Six months after baseline, employees in the intervention group had better work ability, less burnout, and better quality of life than employees in the control group. Two years after randomisation no differences between the two groups were found.

CONCLUSIONS

This occupational health intervention programme proved to be a promising intervention in the prevention of early retirement.

Quality of life after transhiatal compared with extended transthoracic resection for adenocarcinoma of the esophagus

PURPOSE

To assess 3 years of quality of life in patients with esophageal cancer in a randomized trial comparing limited transhiatal resection with extended transthoracic resection.

PATIENTS AND METHODS

Quality-of-life questionnaires were sent at baseline and at 5 weeks; 3, 6, 9, and 12 months; and 1.5, 2, 2.5, and 3 years after surgery. Physical and psychological symptoms, activity level, and global quality of life were assessed with the disease-specific Rotterdam Symptom Checklist. Generic quality of life was measured with the Medical Outcomes Study Short Form-20.

RESULTS

A total of 199 patients participated. Physical symptoms and activity level declined after the operation and gradually returned toward baseline within the first year (P < .01). Psychological well-being consistently improved after baseline (P < .01), whereas global quality of life showed a small initial decline followed by continuous gradual improvement (P < .01). Quality of life stabilized in the second and third year. Three months after the operation, patients in the transhiatal esophagectomy group (n = 96) reported fewer physical symptoms (P = .01) and better activity levels (P < .01) than patients in the transthoracic group (n = 103), but no differences were found at any other measurement point. For psychological symptoms and global quality of life, no differences were found at any follow-up measurement. A similar pattern was found for generic quality of life.

CONCLUSION

No lasting differences in quality of life of patients who underwent either transhiatal or transthoracic resection were found. Compared with baseline, quality of life declined after the operation but was restored within a year in both groups.

Supervisory behaviour as a predictor of return to work in employees absent from work due to mental health problems

AIMS

To study supervisory behaviour as a predictive factor for return to work of employees absent due to mental health problems; and to explore the association between conditional factors and supervisory behaviour.

METHODS

Eighty five supervisors of employees were interviewed by telephone. Questionnaires providing information on person related factors, depressive symptoms, and sickness absence were sent to the employees at baseline, three months, six months, and after one year. Three aspects of supervisory behaviour during the period of absence were measured: communication with the employee, promoting gradual return to work, and consulting of other professionals.

RESULTS

Better communication between supervisor and employee was associated with time to full return to work in non-depressed employees. For employees with a high level of depressive symptoms, this association could not be established. Consulting other professionals more often was associated with a longer duration of the sickness absence for both full and partial return to work. If sickness absence had financial consequences for the department, the supervisor was more likely to communicate frequently with the employee. Supervisors who were responsible for return to work in their organisation were more likely to communicate better and to consult more often with other professionals.

CONCLUSION

Supervisors should communicate more frequently with employees during sickness absence as well as hold follow up meetings more often as this is associated with a faster return to work in those employees.

Is a single-item visual analogue scale as valid, reliable and responsive as multi-item scales in measuring quality of life?

PURPOSE

To compare the validity, reliability and responsiveness of a single, global quality of life question to multi-item scales.

METHOD

Data were obtained from 83 consecutive patients with oesophageal adenocarcinoma undergoing either transhiatal or transthoracic oesophagectomy. Quality of life was measured at baseline, 5 weeks, 3 and 12 months post-operatively with a single-item Visual Analogue Scale (VAS) ranging from 0 to 100, the multi-item Medical Outcomes Study Short Form-20 (MOS SF-20) and Rotterdam Symptom Check-List (RSCL). Convergent and discriminant validity, test-retest reliability and both distribution-based and anchor-based responsiveness were evaluated.

MAJOR FINDINGS

At baseline and at 5 weeks, the VAS showed high correlations with the MOS SF-20 health perceptions scale (r = 0.70 and 0.72) and moderate to high correlations with all other subscales of the MOS SF-20 and RSCL (r = 0.29-0.70). The test-retest reliability intra-class correlation for the VAS was 0.87. At 5 weeks post-operatively, the distribution-based responsiveness was moderate for the VAS (standardised response mean: -0.47; effect size: -0.56), high for the physical subscales of the MOS SF-20 and RSCL (-1.08 to -1.51) and low for the psychological subscales (0.11 to -0.25). Five weeks post-operatively, anchor-based responsiveness was highest for the VAS (r = 0.54).

CONCLUSION

The VAS is an instrument with good validity, excellent reliability, moderate distribution-based responsiveness and good anchor-based responsiveness compared to multi-item questionnaires. Its use is recommended in clinical trials to assess global quality of life.

The Depression Anxiety Stress Scales (DASS): detecting anxiety disorder and depression in employees absent from work because of mental health problems

AIMS

To (1) evaluate the psychometric properties and (2) examine the ability to detect cases with anxiety disorder and depression in a population of employees absent from work because of mental health problems.

METHODS

Internal consistency, construct validity, and criterion validity of the Depression Anxiety Stress Scales (DASS) were assessed. Furthermore, the ability to identify anxiety disorders or depression was evaluated by calculating posterior probabilities of these disorders following positive and negative test results for different cut off scores of the DASS-Depression and DASS-Anxiety subscales.

RESULTS

Internal consistency of the DASS subscales was high, with Cronbach's alphas of 0.94, 0.88, and 0.93 for depression, anxiety, and stress respectively. Factor analysis revealed a three factor solution, which corresponded well with the three subscales of the DASS. Construct validity was further supported by moderately high correlations of the DASS with indices of convergent validity (0.65 and 0.75), and lower correlations of the DASS with indices of divergent validity (range -0.22 to 0.07). Support for criterion validity was provided by a statistically significant difference in DASS scores between two diagnostic groups. A cut off score of 5 for anxiety and 12 for depression is recommended. The DASS showed probabilities of anxiety and depression after a negative test result of 0.05 and 0.06 respectively. Probabilities of 0.29 for anxiety disorder and 0.33 for depression after a positive test result reflect relatively low specificity of the DASS.

CONCLUSION

The psychometric properties of the DASS are suitable for use in an occupational health care setting. The DASS can be helpful in ruling out anxiety disorder and depression in employees with mental health problems.

Transhiatal vs extended transthoracic resection in oesophageal carcinoma: patients' utilities and treatment preferences

To assess patients' utilities for health state outcomes after transhiatal or transthoracic oesophagectomy for oesophageal cancer and to investigate the patients' treatment preferences for either procedure. The study group consisted of 48 patients who had undergone either transhiatal or transthoracic oesophagectomy. In an interview they were presented with eight possible health states following oesophagectomy. Visual Analogue Scale and standard gamble techniques were used to measure utilities. Treatment preference for either transhiatal or transthoracic oesophagectomy was assessed. Highest scores were found for the patients' own current health state (Visual Analogue Scale: 0.77; standard gamble: 0.97). Lowest scores were elicited for the health state "irresectable tumour" (Visual Analogue Scale: 0.13; standard gamble: 0.34). The Visual Analogue Scale method produced lower estimates (P<0.001) than the standard gamble method for all health states. Most patient characteristics and clinical factors did not correlate with the utilities. Ninety-five per cent of patients who underwent a transthoracic procedure and 52% of patients who underwent a transhiatal resection would prefer the transthoracic treatment. No significant associations between any patient characteristics or clinical characteristics and treatment preference were found. Utilities after transhiatal or transthoracic oesophagectomy were robust because they generally did not vary by patient or clinical characteristics. Overall, most patients preferred the transthoracic procedure.
