Adding value for clients during work disability assessments: A qualitative exploration from the perspective of medical examiners.

BACKGROUND: Value-based healthcare delivery focuses on optimizing care provided by measuring the healthcare outcomes which are most important to the clients relative to the total care costs. However, the understanding of what adds value for clients during work disability assessment is lacking. OBJECTIVE: To explore what medical examiners (MEs) perceive as valuable during the work disability assessment process, by exploring possible: 1) facilitators, 2) barriers and 3) opportunities to add value for the client during the work disability assessment. METHODS: For this explorative qualitative study, 7 semi-structured interviews were conducted with MEs in the Netherlands. Thematic coding was performed for all interviews. RESULTS: A large variety of facilitators (n = 22), barriers (n = 17) and opportunities (n = 11) were identified and inductively subdivided into four main themes: 1) coherent process, including all time related aspects, 2) interdisciplinary collaboration, including all aspects related to the collaboration between the ME and other professionals, 3) client-centred interaction, including all aspects related to the supportive interplay from the ME towards the client, and 4) information provision on all aspects during the work disability assessment process towards the client to ensure a valuable work disability assessment process. CONCLUSIONS: The overview of identified possible facilitators, barriers and opportunities to add value for clients from the perspective of the ME may stimulate improvement in the current work disability assessment practice and to better match the client needs.

Towards person-centred work-focused healthcare for people with cardiovascular disease: a qualitative exploration of patients' experiences and needs.

PURPOSE: To explore the experiences and needs concerning work-focused healthcare of patients experiencing problems with work participation due to cardiovascular disease based on all facets of person-centred care. METHODS: Nineteen patients who experienced or continue to experience problems with work participation due to cardiovascular disease participated in semi-structured interviews preceded by preparatory written assignments. The transcripts were analysed by means of directed qualitative content analysis. Adapted principles of the Picker Institute for Person-Centred Care provided a template for the analysis. RESULTS: 28 experiences and needs emerged and were grouped into the eight principles for person-centred work-focused healthcare. Randomly presenting one theme for each of the eight principles, the themes included: (1) frequent encounters with occupational healthcare professionals; (2) substantive work-related advice; (3) transparency in communication; (4) support for family; (5) information provision on the work-focused healthcare process; (6) personal control during the process; (7) empathy for the personal situation; and (8) tailored work-focused support. CONCLUSIONS: The identified experiences and needs for work-focused healthcare of patients experiencing problems with work participation due to cardiovascular disease clearly indicate the need to improve the delivery of person-centred work-focused healthcare to better meet the individual needs of patients.

Provided work-focused healthcare services do not always align with the patient's needs when experiencing disease-related sick leave, potentially impacting their ability to stay in or return to work.This overview of patients' experiences and needs for work-focused healthcare may provide professionals with better insight into the patients' needs and aids to adapt the healthcare provision to these needs.When professionals target the patient's needs, it may facilitate better provision of person-centred work-focused healthcare.

Performance of a RAD51-based functional HRD test on paraffin-embedded breast cancer tissue.

PURPOSE: BRCA-deficient breast cancers (BC) are highly sensitive to platinum-based chemotherapy and PARP inhibitors due to their deficiency in the homologous recombination (HR) pathway. However, HR deficiency (HRD) extends beyond BRCA-associated BC, highlighting the need for a sensitive method to enrich for HRD tumors in an alternative way. A promising approach is the use of functional HRD tests which evaluate the HR capability of tumor cells by measuring RAD51 protein accumulation at DNA damage sites. This study aims to evaluate the performance of a functional RAD51-based HRD test for the identification of HRD BC. METHODS: The functional HR status of 63 diagnostic formalin-fixed paraffin-embedded (FFPE) BC samples was determined by applying the RAD51-FFPE test. Samples were screened for the presence of (epi)genetic defects in HR and matching tumor samples were analyzed with the RECAP test, which requires ex vivo irradiated fresh tumor tissue on the premise that the HRD status as determined by the RECAP test faithfully represented the functional HR status. RESULTS: The RAD51-FFPE test identified 23 (37%) of the tumors as HRD, including three tumors with pathogenic variants in BRCA1/2. The RAD51-FFPE test showed a sensitivity of 88% and a specificity of 76% in determining the HR-class as defined by the RECAP test. CONCLUSION: Given its high sensitivity and compatibility with FFPE samples, the RAD51-FFPE test holds great potential to enrich for HRD tumors, including those associated with BRCA-deficiency. This potential extends to situations where DNA-based testing may be challenging or not easily accessible in routine clinical practice. This is particularly important considering the potential implications for treatment decisions and patient stratification.

Work-focused healthcare from the perspective of employees living with cardiovascular disease: a patient experience journey mapping study.

BACKGROUND: People living with cardiovascular diseases (CVD) often experience work participation problems. Good work-focused healthcare, defined as the received advice, treatment, and guidance focusing on work participation, can support the patient and work place. However, experiences with work-focused healthcare are generally not always positive which is a barrier for work participation. Therefore, the objective of this study is to gain insight into the work-focused healthcare journey from the perspective of patients with work participation problems due to CVD, to understand their experiences and needs, and to derive opportunities for improving work-focused healthcare service at a system level. METHODS: Semi-structured interviews, preceded by preparatory assignments, were conducted with 17 patients who experience(d) work participation problems due to CVD. The patient experience journey map (PEJM) approach was used to visualize the patients' work-focused healthcare journey, including experiences and needs over time and place, from which opportunities to improve work-focused healthcare from the patient's perspective were derived. RESULTS: An aggregated PEJM consisting of six phases was composed and graphically mapped. The first phase, working, represents a period in which CVD health problems and subsequent functional limitations occur. The next two phases, short- and long-term sick leave, represent a period of full sick leave. The last three phases, start-, partial-, and full vocational reintegration, focus on the process of return to work that takes place ranging from a few months up to several years after sick-listing. For each phase the touchpoints, timespan, stakeholders, activities, experiences and needs from the perspective of the patients were identified. Finally, for better work-focused healthcare nine opportunities for improvement were derived from the PEJM, e.g. emphasize the need for work adjustment prior to the medical intervention, provide more personalized advice on handling work limitations, and putting more compelling pressure on the employer to create suitable work positions for their employees. DISCUSSION/CONCLUSION: This paper contributes insights to provide a more patient-centered work-focused healthcare trajectory for patients employed in paid jobs when living with CVD. The PEJM provides an understanding of the patients' perspectives throughout their work-focused healthcare journey and highlights opportunities for improvement towards a better suited and seamless patient journey, Although this research was conducted within the Dutch healthcare system, it can be assumed that the findings on integrated work-focused healthcare are largly transferable to other healthcare systems.

Development of the core of an ICF-based instrument for the assessment of work capacity and guidance in return to work of employees on sick leave: a multidisciplinary modified Delphi study.

BACKGROUND: Several occupational health disciplines are involved in return to work guidance, implying that good interdisciplinary collaboration is important. A shared conceptual framework and a common language for the assessment of work capacity and guidance in return to work is expected to be at the benefit of appropriate and sustainable employability of sick employees. The International Classification of Functioning, Disability and Health (ICF) can be considered a shared conceptual framework and is also promising in terms of a common language. The purpose of the current study is to reach multidisciplinary consensus among occupational health professionals on the content of an ICF-based instrument for the assessment of work capacity and guidance in return to work. METHODS: To obtain multidisciplinary consensus we conducted a modified Delphi study among twelve occupational health experts, including four occupational physicians, four insurance physicians and four labour experts. The study included two e-mail rounds and two virtual meetings. In the consecutive rounds the experts assessed ICF items as well as a list of non-ICF-based work-related environmental factors on their relevance for the assessment of the work capacity and guidance in return to work together with their interpretability. RESULTS: The four consecutive Delphi rounds resulted in 20 items that are minimally needed for the assessment of the work capacity and return to work possibilities of employees on sick leave. The final list included six items on personal functioning, seven items on social functioning and seven items on physical functioning. CONCLUSIONS: This set of items forms the core of an ICF-based instrument, which is expected to facilitate interdisciplinary and intradisciplinary communication because of the use of a shared conceptual framework. As such, it should be of help in the guidance in return to work of employees on sick leave and contribute to appropriate and sustainable employability.

Divergent Molecular and Cellular Responses to Low and High-Dose Ionizing Radiation.

Cancer risk after ionizing radiation (IR) is assumed to be linear with the dose; however, for low doses, definite evidence is lacking. Here, using temporal multi-omic systems analyses after a low (LD; 0.1 Gy) or a high (HD; 1 Gy) dose of X-rays, we show that, although the DNA damage response (DDR) displayed dose proportionality, many other molecular and cellular responses did not. Phosphoproteomics uncovered a novel mode of phospho-signaling via S12-PPP1R7, and large-scale dephosphorylation events that regulate mitotic exit control in undamaged cells and the G2/M checkpoint upon IR in a dose-dependent manner. The phosphoproteomics of irradiated DNA double-strand breaks (DSBs) repair-deficient cells unveiled extended phospho-signaling duration in either a dose-dependent (DDR signaling) or independent (mTOR-ERK-MAPK signaling) manner without affecting signal magnitude. Nascent transcriptomics revealed the transcriptional activation of genes involved in NRF2-regulated antioxidant defense, redox-sensitive ERK-MAPK signaling, glycolysis and mitochondrial function after LD, suggesting a prominent role for reactive oxygen species (ROS) in molecular and cellular responses to LD exposure, whereas DDR genes were prominently activated after HD. However, how and to what extent the observed dose-dependent differences in molecular and cellular responses may impact cancer development remain unclear, as the induction of chromosomal damage was found to be dose-proportional (10-200 mGy).

The effect of the Progressive Goal Attainment Program on cognitions, perceptions, and work participation of workers with chronic health problems: study protocol for a randomized controlled trial.

BACKGROUND: Cognitions and perceptions of workers with chronic health problems, such as catastrophizing thoughts and fear-avoidance beliefs, can negatively influence work participation. The Progressive Goal Attainment Program (PGAP) is an intervention developed in Canada with the aim of decreasing limiting cognitions and perceptions and increasing work participation. The objective of this protocol article is to describe the design of a randomized controlled superiority trial to study whether PGAP is effective in decreasing limiting cognitions and perceptions and increasing workability and work participation of workers with chronic health problems in the Netherlands. METHODS: This study is a randomized controlled superiority trial with two (parallel) groups, in which workers on sick leave are randomly assigned to an intervention group (PGAP intervention) or to a waiting-list control group (care as usual). The PGAP intervention consists of a maximum of 10 weekly individual sessions provided by a trained PGAP professional in which the worker learns about staying active, planning activities, and setting goals. Participants in this risk-targeted behavioral activation intervention also learn to be more aware of their cognitions and perceptions and learn about solution-focused problem-solving skills in challenging situations. The primary outcome is the degree of catastrophizing. Secondary outcomes are other personal cognitions and perceptions (e.g., expectations regarding return to work, self-efficacy), health symptoms (e.g., fatigue, depression), work participation (e.g., sick leave status, work hours), and other work-related outcomes (e.g., workability, quality of working life). DISCUSSION: Although PGAP shows positive effects in Canada, we do not know whether this intervention is effective in the Netherlands. This study is the first randomized controlled trial to test the effect of PGAP on limiting cognitions and perceptions and on work participation of workers with chronic health problems in the Netherlands. If PGAP is effective it could be implemented in the Netherlands in order to stimulate workability and work participation of workers. TRIAL REGISTRATION: The protocol of this study is registered in the Netherlands Trial Register (NL9832) in October 2021.

The relationship between the living lab approach and successful implementation of healthcare innovations: an integrative review.

OBJECTIVES: The concept of living labs as a research method to enhance participation of end-users in the development and implementation process of an innovation, gained increasing attention over the past decade. A living lab can be characterised by five key components: user-centric, cocreation, real-life context, test innovation and open innovation. The purpose of this integrative literature review was to summarise the literature on the relationship between the living lab approach and successful implementation of healthcare innovations. METHODS: An integrative literature review searching PubMed, EMBASE, PsycINFO and Cinahl databases between January 2000 and December 2019. Studies were included when a living lab approach was used to implement innovations in healthcare and implementation outcomes were reported. Included studies evaluated at least one of the following implementation outcomes: acceptability, adoption, appropriateness, feasibility, fidelity, implementation cost, penetration or sustainability. Quality was assessed based on a tool developed by Hawker et al. RESULTS: Of the 1173 retrieved articles, 30 studies were included of which 11 of high quality. Most studies involved a combination of patients/public (N=23) and providers (N=17) as key stakeholders in the living lab approach. Living lab components were mostly applied in the development phase of innovations (N=21). The majority of studies reported on achievement of acceptability (N=22) and feasibility (N=17) in terms of implementation outcomes. A broader spectrum of implementation outcomes was only evaluated in one study. We found that in particular six success factors were mentioned for the added-value of using living lab components for healthcare innovations: leadership, involvement, timing, openness, organisational support and ownership. CONCLUSIONS: The living lab approach showed to contribute to successful implementation outcomes. This integrative review suggests that using a living lab approach fosters collaboration and participation in the development and implementation of new healthcare innovations.

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

PURPOSE: To explore workers' views and considerations on involving their significant others (SOs) in occupational health care. METHODS: Four focus group interviews in the Netherlands, with 21 workers who had visited an occupational health physician (OHP) due to work absence caused by a chronic disease. Data was analyzed using thematic analysis. RESULTS: We distinguished four main themes: (i) attitudes towards involving SOs, (ii) preferences on how to involve SOs, (iii) benefits of involving SOs, and (iv) concerns with regard to involving SOs. Workers expressed both positive and critical opinions about involving SOs in occupational health care. Benefits mentioned included provision of emotional and informational support by SOs before, during, and after consultations. According to workers, support from SOs can be enhanced by informing SOs about re-integration plans and involving them in decision making. However, workers were concerned about overburdening SOs, and receiving unwanted support from them. CONCLUSIONS: According to interviewed workers, engagement of SOs in occupational health care can help workers with a chronic disease in their recovery and return to work. However, they felt it is important to take SO characteristics and the worker's circumstances and preferences into account, and to balance the potential benefits and drawbacks of involving SOs.Implications for rehabilitationThis study suggests that the worker's re-integration process could benefit from informing significant others about the return to work plans, involving them in decision-making, and explicitly discussing how the significant other can support the worker.Occupational health physicians have an important role in informing workers about the possibility and potential benefits of involving their significant others in the re-integration process.The involvement of a significant other in the re-integration process needs to be tailored to the specific situation of the individual worker, taking into account the preferences of both the worker and significant other.Findings suggest that it is important that occupational health physicians, workers and significant others are not only aware of the possible benefits of significant other involvement, but also of potential drawbacks such as interference during consultations, overburdening significant others, and significant others providing unwanted support.

The RAD51-FFPE Test; Calibration of a Functional Homologous Recombination Deficiency Test on Diagnostic Endometrial and Ovarian Tumor Blocks.

PARP inhibitor (PARPi) sensitivity is related to tumor-specific defects in homologous recombination (HR). Therefore, there is great clinical interest in tests that can rapidly and reliably identify HR deficiency (HRD). Functional HRD tests determine the actual HR status by using the (dis)ability to accumulate RAD51 protein at sites of DNA damage as read-out. In this study, we further improved and calibrated a previously described RAD51-based functional HRD test on 74 diagnostic formalin-fixed paraffin-embedded (FFPE) specimens (RAD51-FFPE test) from endometrial cancer (EC n = 25) and epithelial ovarian cancer (OC n = 49) patients. We established optimal parameters with regard to RAD51 foci cut-off (≥2) and HRD threshold (15%) using matched endometrial and ovarian carcinoma specimens for which HR status had been established using a RAD51-based test that required ex vivo irradiation of fresh tissue (RECAP test). The RAD51-FFPE test detected BRCA deficient tumors with 90% sensitivity and RECAP-HRD tumors with 87% sensitivity, indicating that it is an attractive alternative to DNA-based tests with the potential to be applied in routine diagnostic pathology.

Assessing significant others' cognitions and behavioral responses in occupational health care for workers with a chronic disease.

PURPOSE: To examine current practices of occupational health professionals in assessing significant others' cognitions and behavioral responses that may influence work outcomes of workers with a chronic disease. METHODS: A survey study among occupational health professionals, focusing on the assessment of illness perceptions, work-related beliefs and expectations, and behavioral responses of significant others of workers with a chronic disease. We performed linear regression analyses to investigate which factors are related to occupational health professionals' assessment practices. We used thematic analysis to analyze qualitative data on occupational health professionals' reasons to assess or overlook significant others' cognitions and behavioral responses. RESULTS: Our study sample included 192 occupational health professionals. Most seldom asked about significant others' cognitions and behavioral responses. Organizational norms and occupational health professionals' self-efficacy were related to reported assessment practices. Reasons to assess significant others' cognitions and behavioral responses included recognizing their influence on work participation, and occurrence of stagnation. However, occupational health professionals indicated some doubt whether such assessment would always contribute to better care. CONCLUSIONS: It is not common practice for occupational health professionals to assess significant others' cognitions and behavioral responses, although they recognize the influence of these factors on work outcomes. More research is needed as to how occupational health professionals can best address the role of significant others, and apply these new insights in their daily practice.Implications for rehabilitationMost occupational health professionals do not commonly ask about significant others' cognitions and behavioral responses despite the possible influence of these factors on work outcomes.Occupational health professionals may be able to better support workers with a chronic disease by paying more attention to the influence of significant others.Aside from asking about practical support, occupational health professionals should consider asking about significant others' illness perceptions, work-related beliefs and expectations, and other behavioral responses.

The RECAP Test Rapidly and Reliably Identifies Homologous Recombination-Deficient Ovarian Carcinomas.

Recent studies have shown that the efficacy of PARP inhibitors in epithelial ovarian carcinoma (EOC) is related to tumor-specific defects in homologous recombination (HR) and extends beyond BRCA1/2 deficient EOC. A robust method with which to identify HR-deficient (HRD) carcinomas is therefore of utmost clinical importance. In this study, we investigated the proficiency of a functional HR assay based on the detection of RAD51 foci, the REcombination CAPacity (RECAP) test, in identifying HRD tumors in a cohort of prospectively collected epithelial ovarian carcinomas (EOCs). Of the 39 high-grade serous ovarian carcinomas (HGSOC), the RECAP test detected 26% (10/39) to be HRD, whereas ovarian carcinomas of other histologic subtypes (n = 10) were all HR-proficient (HRP). Of the HRD tumors that could be sequenced, 8/9 showed pathogenic BRCA1/2 variants or BRCA1 promoter hypermethylation, indicating that the RECAP test reliably identifies HRD, including but not limited to tumors related to BRCA1/2 deficiency. Furthermore, we found a trend towards better overall survival (OS) of HGSOC patients with RECAP-identified HRD tumors compared to patients with HRP tumors. This study shows that the RECAP test is an attractive alternative to DNA-based HRD tests, and further development of a clinical grade RECAP test is clearly warranted.

Influence of significant others on work participation of individuals with chronic diseases: a systematic review.

OBJECTIVE: It is widely recognised that significant others (SOs), such as a partner, family member or friend, can influence health outcomes of individuals with a chronic disease. However, not much is known about which specific cognitions (ie, illness perceptions and expectation of work ability) and behaviours (eg, emotional and practical support) of SOs influence work participation. Therefore, we aimed to identify cognitions and behaviours of SOs that are related to work participation of individuals with a chronic disease. DESIGN: A systematic review and thematic synthesis. DATA SOURCES: PubMed, Embase, PsycINFO, SocINDEX and Web of Science were searched until 28 March 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included studies reporting on cognitions and behaviours of SOs related to work participation in populations with various chronic diseases. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted the data and performed a quality assessment using the Quality Assessment Tool for Quantitative Studies from the Effective Public Health Practice Project 2007 and a checklist for assessment of qualitative studies derived from the Cochrane Supplemental Handbook Guidance. Evidence was thematically synthesised. RESULTS: Out of 5168 articles, 18 were included (15 qualitative and 3 quantitative) of moderate to high quality. Studies were on cancer, chronic pain, brain injuries and mental health disorders. After thematic synthesis 27 factors could be distinguished. Consistent evidence was found that SOs' positive and encouraging attitudes regarding work participation, encouragement and motivating behaviour and open communication with patients are facilitators for work participation. Consistently reported barriers were SOs' positive attitudes towards sickness absence and advise, encouragement or pressure to refrain from work. CONCLUSIONS: Our findings show that several cognitions and behaviours of SOs can facilitate or hinder work participation of individuals with a chronic disease. Intervening on these factors by involving SOs in disability prevention and return to work intervention strategies may be beneficial. More prognostic studies are needed, as the current evidence is mostly based on qualitative studies.

Xenobiotic metabolism in differentiated human bronchial epithelial cells.

Differentiated human bronchial epithelial cells in air liquid interface cultures (ALI-PBEC) represent a promising alternative for inhalation studies with rodents as these 3D airway epithelial tissue cultures recapitulate the human airway in multiple aspects, including morphology, cell type composition, gene expression and xenobiotic metabolism. We performed a detailed longitudinal gene expression analysis during the differentiation of submerged primary human bronchial epithelial cells into ALI-PBEC to assess the reproducibility and inter-individual variability of changes in transcriptional activity during this process. We generated ALI-PBEC cultures from four donors and focussed our analysis on the expression levels of 362 genes involved in biotransformation, which are of primary importance for toxicological studies. Expression of various of these genes (e.g., GSTA1, ADH1C, ALDH1A1, CYP2B6, CYP2F1, CYP4B1, CYP4X1 and CYP4Z1) was elevated following the mucociliary differentiation of airway epithelial cells into a pseudo-stratified epithelial layer. Although a substantial number of genes were differentially expressed between donors, the differences in fold changes were generally small. Metabolic activity measurements applying a variety of different cytochrome p450 substrates indicated that epithelial cultures at the early stages of differentiation are incapable of biotransformation. In contrast, mature ALI-PBEC cultures were proficient in the metabolic conversion of a variety of substrates albeit with considerable variation between donors. In summary, our data indicate a distinct increase in biotransformation capacity during differentiation of PBECs at the air-liquid interface and that the generation of biotransformation competent ALI-PBEC cultures is a reproducible process with little variability between cultures derived from four different donors.

Longitudinal Associations Between Biopsychosocial Factors and Sustainable Return to Work of Sick-Listed Workers with a Depressive or Anxiety Disorder.

PURPOSE: Only a limited number of studies have investigated return to work of sick-listed workers with mental health problems, and more knowledge is needed about the influence of non-disorder-related factors. This study aimed to identify longitudinal associations between demographic, personality, disorder-related and work-related characteristics and sustainable return to work of sicklisted workers with a depressive or anxiety disorder. METHODS: We used data of a large Dutch cohort study to prospectively study longitudinal associations between biopsychosocial factors and sustainable return to work in 2 years. Associations were studied by means of univariable and multivariable logistic regression analysis. Participants who were sick-listed at baseline and had a lifetime diagnosis of a depressive and/or anxiety disorder were included in this study (N = 215). RESULTS: In 2 years, 51.6% of the participants returned to work sustainably. Age, household income, extraversion, employment status, skill discretion and job security were significantly (P B 0.05) associated with sustainable RTW in 2 years in the univariable analyses. The multivariable analysis revealed significant associations between sustainable return to work and age (OR per 10 years = 0.67; 95% CI 0.47­0.95), household income (OR per 100 Euro's a month = 1.04; 95% CI 1.00­1.08) and being on sickness benefit versus being (self-)employed (OR 0.39; 95% CI 0.20­0.77). CONCLUSIONS: In the long-run not disorder-related factors, but an older age, the absence of a job and a low household income seem to complicate return to work. Policy and research should focus on facilitators and barriers for return to work of workers with these characteristics.

Return to work in sick-listed cancer survivors with job loss: design of a randomised controlled trial.

BACKGROUND: Despite long-term or permanent health problems, cancer survivors are often motivated to return to work. For cancer survivors who have lost their job, return to work can be more challenging compared to employed survivors, as they generally find themselves in a more vulnerable social and financial position. Cancer survivors with job loss may therefore be in need of tailored return to work support. However, there is a lack of return to work intervention programs specifically targeting these cancer survivors. The number of cancer survivors with job loss in developed countries is rising due to, amongst others, increases in the incidence and survivor rate of cancer, the retirement age and the proportion of flexible employment contracts. Hence, we consider it important to develop a tailored return to work intervention program for cancer survivors with job loss, and to evaluate its effectiveness compared to usual care. METHODS/DESIGN: This study employs a two-armed randomised controlled trial with a follow-up period of 12 months. The study population (n = 164) will be recruited from a national sample of cancer survivors (18-60 years), who have been sick-listed for 12-36 months. Participants will be randomised by using computerized blocked randomisation (blocks of four). All participants will receive usual care as provided by the Dutch Social Security Agency. Additionally, participants in the intervention group will receive a tailored return to work intervention program, which includes vocational rehabilitation and supportive psychosocial components, as well as (therapeutic) placement at work. The primary outcome measure is duration until sustainable return to work; the secondary outcome measure is rate of return to work. Other parameters include, amongst others, fatigue, coping strategy and quality of life. We will perform Cox regression analyses to estimate hazard ratios for time to sustainable return to work. DISCUSSION: The hypothesis of this study is that a tailored approach for cancer survivors with job loss is more effective, regarding return to work, compared to usual care. The results of this study will provide insight into the ways in which return to work can be facilitated for cancer survivors with job loss. TRIAL REGISTRATION: Netherlands Trial Register: NTR3562 .

Return to work of workers without a permanent employment contract, sick-listed due to a common mental disorder: design of a randomised controlled trial.

BACKGROUND: Workers without a permanent employment contract represent a vulnerable group within the working population. Mental disorders are a major cause of sickness absence within this group. Common mental disorders are stress-related, depressive and anxiety disorders. To date, little attention has been paid to effective return to work interventions for this type of sick-listed workers. Therefore, a participatory supportive return to work program has been developed. It combines elements of a participatory return to work program, integrated care and direct placement in a competitive job.The objective of this paper is to describe the design of a randomised controlled trial to evaluate the cost-effectiveness of this program compared to care as usual. METHODS/DESIGN: The cost-effectiveness of the participatory supportive return to work program will be examined in a randomised controlled trial with a follow-up of twelve months.The program strongly involves the sick-listed worker in the identification of obstacles for return to work and possible solutions, resulting in a consensus based action plan. This plan will be used as a starting point for the search of suitable competitive employment with support of a rehabilitation agency. During this process the insurance physician of the sick-listed worker contacts other caregivers to promote integrated care.Workers eligible to participate in this study have no permanent employment contract, have applied for a sickness benefit at the Dutch Social Security Agency and are sick-listed between two and fourteen weeks due to mental health problems.The primary outcome measure is the duration until first sustainable return to work in a competitive job. Outcomes are measured at baseline and after three, six, nine and twelve months. DISCUSSION: If the participatory supportive return to work program proves to be cost-effective, the social security system, the sick-listed worker and society as a whole will benefit. A cost-effective return to work program will lead to a reduction of costs related to sickness absence. For the sick-listed worker a cost-effective program results in earlier sustainable return to work, which can be associated with both social and health benefits. TRIAL REGISTRATION: The trial registration number and date is NTR3563, August 7, 2012.

Economic evaluation of a participatory return-to-work intervention for temporary agency and unemployed workers sick-listed due to musculoskeletal disorders.

OBJECTIVES: The aim of the study was to evaluate the cost-effectiveness, -utility, and -benefit of a newly developed participatory return-to-work (RTW) program for temporary agency and unemployed workers, sick-listed due to musculoskeletal disorders. METHODS: An economic evaluation was conducted alongside a randomized controlled trial with a 12-month follow-up. Temporary agency and unemployed workers, sick-listed for 2â€"8 weeks due to musculoskeletal disorders, were randomized to the participatory RTW program (N=79) or usual care group (N=84). The new RTW program was aimed at making a consensus-based RTW action plan with the possibility of a temporary (therapeutic) workplace. Effect outcomes were sustainable RTW and quality-adjusted life years (QALY). Healthcare utilization was measured from the social insurer’s perspective and societal perspective. RESULTS: Total healthcare costs in the participatory RTW program group [10 189 (standard deviation [SD] 7055) euros] were statistically significantly higher compared to care-as-usual [7862 (SD 7394) euros]. The cost-effectiveness analyses showed that the new intervention was more effective but also more costly than usual care (ie, to gain RTW one day earlier in the participatory RTW program group approximately 80 euros needed to be invested). The net societal benefit of the participatory RTW program compared to care-as-usual was 2073 euros per worker. CONCLUSIONS: The newly developed participatory RTW program was more effective but also more costly than usual care. The program enhanced work resumption and generated a net socioeconomic benefit. Hence, implementation of the participatory RTW program may have potential to achieve a sustainable contribution of vulnerable workers to the labor force.

No threshold for the induction of chromosomal damage at clinically relevant low doses of X rays.

The recent steep increase in population dose from radiation-based medical diagnostics, such as computed tomography (CT) scans, requires insight into human health risks, especially in terms of cancer development. Since the induction of genetic damage is considered a prominent cause underlying the carcinogenic potential of ionizing radiation, we quantified the induction of micronuclei and loss of heterozygosity events in human cells after exposure to clinically relevant low doses of X rays. A linear dose-response relationship for induction of micronuclei was observed in human fibroblasts with significantly increased frequencies at doses as low as 20 mGy. Strikingly, cells exposed during S-phase displayed the highest induction, whereas non S-phase cells showed no significant induction below 100 mGy. Similarly, the induction of loss of heterozygosity in human lymphoblastoid cells quantified at HLA loci, was linear with dose and reached significance at 50 mGy. Together the findings favor a linear-no-threshold model for genetic damage induced by acute exposure to ionizing radiation. We speculate that the higher radiosensitivity of S-phase cells might relate to the excessive cancer risk observed in highly proliferative tissues in radiation exposed organisms.

A participatory return-to-work program for temporary agency workers and unemployed workers sick-listed due to musculoskeletal disorders: a process evaluation alongside a randomized controlled trial.

INTRODUCTION: Beside (cost-)effectiveness, the feasibility of an intervention is important for successful implementation in daily practice. This study concerns the process evaluation of a newly developed participatory return-to-work (RTW) program for workers without an employment contract, sick-listed due to musculoskeletal disorders. The program consisted of a stepwise process, guided by an independent RTW coordinator, aimed at making a consensus-based RTW plan with the possibility of a temporary (therapeutic) workplace. The aims of this study were to describe the reach and extent of implementation of the new program, the satisfaction and experiences of all stakeholders, and the perceived barriers and facilitators for implementation of the program in daily practice. METHODS: Temporary agency workers and unemployed workers, sick-listed for 2-8 weeks due to musculoskeletal disorders were eligible for this study. Data were collected from the workers; their insurance physicians and labour experts at the Dutch Social Security Agency; RTW coordinators; and case managers from participating vocational rehabilitation agencies. Data collection took place using professionals' reports, standardized matrices, questionnaires at baseline and at 3-month follow-up, and group interviews with the professionals. RESULTS: Of the 79 workers who were allocated to the participatory RTW program group, 72 workers actually started with the intervention. Overall, implementation of the program was performed according to protocol. However, offering of suitable temporary workplaces was delayed with 44.5 days. Results showed satisfaction with the RTW coordinator among the workers and three quarters of the labour experts experienced a minor or major contribution of the presence of the RTW coordinator. Several barriers for implementation were identified, such as the administrative time-investment, unclear information about the program, no timely offering of temporary (therapeutic) workplaces, and the need for additional support in case of complex health problems. CONCLUSIONS: This study indicates overall feasibility for implementation of the participatory RTW program in daily practice. However, to overcome important barriers, more attention should be paid to improve timely offering of suitable temporary workplaces, to describe more clearly the program goals and the professional's roles, and to offer additional support for workers suffering from complex multi-causal health problems.
