Background: The objectives of this study are to explore healthcare workers' (HCWs') mental models regarding psychological distress and to compare these with that of experts., Methods: Semistructured interviews were conducted (n = 28 HCWs, n = 13 experts). The topic list encompassed risk perception, early stress symptoms, causes, consequences, and preventive measures of psychological distress. Interviews were transcribed verbatim and thematically analyzed using MAXQDA (VERBI Software, Berlin)., Results: Similarities were found in risk perception, symptoms, causes, and consequences. Differences arose in HCWs' reliance on personal experiences and values versus experts' scientific perspective. Preventive measures also showed discrepancies. Variation within HCWs was found on all aspects of their mental model., Conclusion: For effective preventive interventions regarding psychological distress, experts should consider HCWs' personal values and experiences, acknowledging the variation in their mental models. This approach may enhance HCWs' engagement in preventive behaviors., Competing Interests: Conflicts of interest: None declared., (Copyright © 2024 The Author(s).

Introduction: The use of performance validity tests (PVTs) in a neuropsychological assessment to determine indications of invalid performance has been a common practice for over a decade. Most PVTs are memory-based; therefore, the Groningen Effort Test (GET), a non-memory-based PVT, has been developed., Objectives: This study aimed to validate the GET in patients with suspected chronic solvent-induced encephalopathy (CSE) using the criterion standard of 2PVTs. A second goal was to determine diagnostic accuracy for GET., Method: Sixty patients with suspected CSE referred for NPA were included. The GET was compared to the criterion standard of 2PVTs based on the Test of Memory Malingering and the Amsterdam Short Term Memory Test., Results: The frequency of invalid performance using the GET was significantly higher compared to the criterion of 2PVTs (51.7% vs. 20.0% respectively; p < 0.001). For the GET index, the sensitivity was 75% and the specificity was 54%, with a Youden's Index of 27., Conclusion: The GET showed significantly more invalid performance compared to the 2PVTs criterion suggesting a high number of false positives. The general accepted minimum norm of specificity for PVTs of >90% was not met. Therefore, the GET is of limited use in clinical practice with suspected CSE patients., (© The Author(s) 2024.

Background: Returning to work after long-term sick leave can be challenging, particularly in small- and medium-sized enterprises (SMEs) where support may be limited. Recognizing the responsibilities and challenges of SME employers, a web-based intervention (hereafter the SME tool) has been developed. The SME tool aims to enhance the employer's intention and ability to support the sick-listed employee. Based on the Self-Determination Theory, it is hypothesized that this intention is enhanced by intervening in the employer's autonomy, competences, and relatedness targeted at, e.g., communication with sick-listed employee, involvement of other stakeholders, and practical support. This is achieved by means of providing templates, communication videos, and information on legislation. This article describes the design of an effect and process evaluation of the SME tool., Methods: A randomized controlled trial (RCT) with a 6-month follow-up will be conducted with a parallel-group design with two arms: an intervention group and a control group. Sick-listed employees (≤ 8 weeks) of SMEs (≤ 250 employees) at risk of long-term sick leave and their employers will be recruited and randomly allocated as a dyad (1:1). Employers randomized to the intervention group receive unlimited access to the SME tool, while those in the control group will receive care as usual. The primary outcome is the satisfaction of the employee with the return to work (RTW) support provided by their employer. Secondary outcomes include social support, work performance, and quality of work life at the employee level and self-efficacy in providing RTW support at the employer level. Outcomes will be assessed using questionnaires at baseline and 1, 3, and 6 months of follow-up. Process evaluation measures include, e.g., recruitment and use of and perceived usefulness of the SME tool. Additionally, semi-structured interviews with employers, employees, and occupational physicians will explore the interpretation of the RCT results and strategies for the national implementation of the SME tool., Discussion: The SME tool is hypothesized to be valuable in addition to usual care helping employers to effectively support the RTW of their long-term sick-listed employees, by improving the employers' intention and ability to support., Trial Registration: ClinicalTrials.gov, NCT06330415.

Background: The Netherlands faces 60% prevalence of chronic conditions by 2040, impacting societal participation and quality of life. Current clinical care inadequately addresses these consequences, and most hospitals do not integrate occupational health in their care., Objectives: To develop a generic person- and work-oriented medical care model (WMCM) based on real life experiences with work-oriented care and supporting the chronically ill in active societal participation., Methods: A qualitative research project with a participative approach in one hospital (November 2019 until March 2020). In an expert meeting, a schematic representation of a work-oriented care model was developed. Subsequent discussion rounds, with professionals from different patient groups, iteratively refined the model to a WMCM., Results: Consensus was reached after seven rounds of discussion, defining the model's core elements (1) a combination of biomedical and biopsychosocial approaches, (2) involvement of a clinical occupational physician in the treatment team, (3) a coordinating role for nursing specialists, and (4) incorporation of a work-oriented intervention plan (WoIP) into the treatment plan. Advocating early attention to societal participation, the model emphasises the WoIP and consensus on monitoring indicators. The final goal is a sustainable return to societal participation, considering both quality of life and work., Conclusion: It is feasible to develop a generic person- and work-oriented care model for patients with chronic illness within a hospital care setting. Collaboration between healthcare professionals and a specialised occupational physician, with a central role for nurses, is deemed crucial., (© 2024. The Author(s).)

Background: Up to 65% of people with multiple sclerosis (PwMS) develop cognitive deficits, which hampers their ability to work, participating in day-to-day life and ultimately reducing quality of life (QoL). Early cognitive symptoms are often less tangible to PwMS and their direct environment and are noticed only when symptoms and work functioning problems become more advanced, i.e., when (brain) damage is already advanced. Treatment of symptoms at a late stage can lead to cognitive impairment and unemployment, highlighting the need for preventative interventions in PwMS., Aims: This study aims to evaluate the (cost-) effectiveness of two innovative preventative interventions, aimed at postponing cognitive decline and work functioning problems, compared to enhanced usual care in improving health-related QoL (HRQoL)., Methods: Randomised controlled trial including 270 PwMS with mild cognitive impairment, who have paid employment ≥ 12 h per week and are able to participate in physical exercise (Expanded Disability Status Scale < 6.0). Participants are randomised across three study arms: 1) 'strengthening the brain' - a lifestyle intervention combining personal fitness, mental coaching, dietary advice, and cognitive training; 2) 'strengthening the mind' - a work-focused intervention combining the capability approach and the participatory approach in one-on-one coaching by trained work coaches who have MS themselves; 3) Control group-receiving general information about cognitive impairment in MS and receiving care as usual. Intervention duration is four months, with short-term and long-term follow-up measurements at 10 and 16 months, respectively. The primary outcome measure of the Don't be late! intervention study will be HRQoL as measured with the 36-item Short Form. Secondary outcomes include cognition, work related outcomes, physical functioning, structural and functional brain changes, psychological functioning, and societal costs. Semi-structured interviews and focus groups with stakeholders will be organised to qualitatively reflect on the process and outcome of the interventions., Discussion: This study seeks to prevent (further) cognitive decline and job loss due to MS by introducing tailor-made interventions at an early stage of cognitive symptoms, thereby maintaining or improving HRQoL. Qualitative analyses will be performed to allow successful implementation into clinical practice., Trial Registration: Retrospectively registered at ClinicalTrials.gov with reference number NCT06068582 on 10 October 2023., (© 2024.

Background: Cognitive impairment occurs in up to 65% of people with multiple sclerosis (PwMS), negatively affecting daily functioning and health-related quality of life. In general, neuropsychological testing is not part of standard MS-care due to insufficient time and trained personnel. Consequently, a baseline assessment of cognitive functioning is often lacking, hampering early identification of cognitive decline and change within a person over time. To assess cognitive functioning in PwMS in a time-efficient manner, a BICAMS-based self-explanatory digital screening tool called the Multiple Screener © , has recently been developed. The aim of the current study is to validate the Multiple Screener © in a representative sample of PwMS in the Netherlands. Additionally, we aim to investigate how cognitive functioning is related to psychological factors, and both work and societal participation., Methods: In this cross-sectional multicentre study, 750 PwMS (aged 18-67 years) are included. To obtain a representative sample, PwMS are recruited via 12 hospitals across the Netherlands. They undergo assessment with the Minimal Assessment of Cognitive Functioning in MS (MACFIMS; reference-standard) and the Multiple Screener © . Sensitivity, specificity, and predictive values for identifying (mild) cognitive impairment are determined in a subset of 300 participants. In a second step, the identified cut-off values are tested in an independent subset of at least 150 PwMS. Moreover, test-retest reliability for the Multiple Screener © is determined in 30 PwMS. Information on psychological and work-related factors is assessed with questionnaires., Discussion: Validating the Multiple Screener © in PwMS and investigating cognition and its determinants will further facilitate early identification and adequate monitoring of cognitive decline in PwMS., (© 2024.

Backgrounds: The detection of biomarkers of a stress response in the stratum corneum (SC) could be used as objective assessment of early stress symptoms and monitoring of stress reduction interventions in health care workers (HCWs)., Aim: The aim of this study is to explore SC biomarkers of immune and hormonal response and skin barrier for assessment of psychological distress (PD) in HCWs., Methods: Twenty-five female HCWs and 25 non-HCWs participated. SC samples were collected using adhesive tapes at baseline and 3-5 days later (T1). We analyzed 24 biomarkers (immunological, vascular, hormones, and natural moisturizing factors). Stress symptoms were assessed using three scales of Copenhagen Psychosocial Questionnaire. The study involved: identifying SC biomarkers, correlating stress symptoms and biomarkers at baseline and T1, examining stress symptoms between the groups with a Mann-Whitney test, comparing stress symptoms and biomarkers between groups using Ordinary Least Regression and investigating temporal variability of SC biomarkers at baseline and T1 using a Wilcoxon-signed rank., Results: Fourteen SC biomarkers were identified. We found correlations between general stress and "IL18" ( r  = 0.55) physical stress and "IL1b" ( r  = 0.36) and cognitive stress and "MIP3a" ( r  = 0.38) at baseline and general stress and cortisol ( r  = -0.49), physical stress and cortisol ( r  = -0.60) and cortisone ( r  = -0.67) at T1. We found no differences in stress symptoms and biomarkers between the groups, except for "MIP3a" at baseline. Differences in the biomarker levels between two time points were found for "TARC," "VEGFA," "ILRA," "IL1RA/IL1a," "NMF," and "DHEA.", Conclusion: The SC can be suitable biological material to assess biomarkers related to immune response, hormonal response, and skin barrier function. The SC biomarkers, showed strong, moderate and weak correlations with stress symptoms. Notably, these associations include cytokines of innate immunity and well-known stress hormones, cortisol and cortisone., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

Background: Common mental disorders (CMD) are highly prevalent among sick-listed precarious workers and often lead to long-term sickness-absence, work disability and unemployment. This study aimed to identify predictors of a longer time until return to work (RTW) and prolonged duration of sickness absence in sick-listed precarious workers with CMD., Methods: We conducted a secondary Cox regression analysis using existing data from two Dutch randomized controlled trials and one cohort study among sick-listed precarious workers with CMD (N = 681). Age, gender, baseline employment status, study allocation, severity of psychological symptoms and RTW self-efficacy were evaluated for their predictive value on time until sustainable (≥ 28 days) RTW and duration of sickness absence during 12-month follow-up. In this study, time until sustainable RTW and duration of sickness absence are distinct dependent variables, because they are not mutually exclusive., Results: Age above 50 years (HR 0.57, 95% CI 0.39-0.82), severe psychological symptoms (HR 0.64, 95% CI 0.43-0.93), unemployment (HR 0.19 95% CI 0.11-0.33) and loss of employment contract during sickness absence (HR 0.25, 95% CI 0.14-0.47) were predictive of a longer time until RTW. Male gender (HR 0.77, 95% CI 0.62-0.97), severe psychological symptoms (HR 0.64, 95% CI 0.46-0.87), unemployment (HR 0.47, 95% CI 0.27-0.84) and loss of employment contract (HR 0.48, 95% CI 0.26-0.90) predicted a prolonged duration of sickness absence., Conclusions: Unemployment at the moment of sick-listing, loss of employment contract during sickness absence, and severe psychological symptoms are predictors of both a longer time until RTW and prolonged duration of sickness absence among sick-listed precarious workers with CMD. This knowledge assists occupational health and mental health professionals in the early identification of workers at risk of long-term sickness absence, enabling them to arrange targeted occupational rehabilitation support and mental health care., Trial Registration: The included randomized controlled trials were prospectively registered in the Dutch national trial register under NTR4190 (September 27, 2013) and NTR3563 (August 7, 2012)., (© 2023.

Objective: Work-related mental health problems are a major and growing public and occupational health issue. Although prevention of work-related disease is a central task in the work of occupational physicians, implementation of preventive tasks can still improve. The aim of this paper is to present the development of an intervention to support occupational physicians in the execution of preventive tasks and a protocol for its evaluation., Methods: An intervention to support occupational physicians has been developed making use of the implementation mapping protocol. The intervention was based on barriers and facilitators for the execution of preventive tasks, input from stakeholders, and evidence-based strategies from literature., Results: The intervention consists of three peer group supervision meetings directed to preventive tasks. During these meetings, occupational physicians will receive materials and will use goal-setting to formulate their own action plans. The IM-PROmPt-study (Implementation of PReventive tasks by Occupational Physicians) is a two-armed cluster randomized controlled trial, comparing peer group supervision directed to the implementation of preventive tasks for occupational physicians with usual peer group supervision. The evaluation will include an effect and process evaluation to examine if the intervention is successful in supporting OPs to implement preventive activities, specifically aimed to prevent work-related mental health problems., Discussion: The intervention is expected to lead to more knowledge and awareness of the value of prevention among OPs, anticipated to lead to both organizational and individual gains., Trial Registration: ISRCTN registry; ISRCTN15394765.

Purpose: Performing evidence-based work disability prognosis evaluation (WDPE) of clients on sick leave is a difficult task for physicians. The aim was to develop a working method to support physicians in performing evidence-based WDPE and to improve WDPE quality., Materials and Methods: Intervention Mapping (IM) supplemented with elements of the Behavior Change Wheel (BCW) guided project planning for developing the working method. This approach allowed combination with other frameworks and, e.g., behavior change theories. WDPE quality challenges were analyzed on various ecological levels, e.g., the individual (i.e., the physician), interpersonal (i.e., the client) and organizational level, culminating into a multilevel logic model of the problem. Determinants that contributed to this problem, e.g., lack of physicians' knowledge on performing evidence-based WDPE, were identified. Performance objectives were formulated that could contribute to a desired change in WDPE quality. From the performance objectives and determinants (e.g., knowledge), change objectives were derived. In order to achieve these change objectives, suitable intervention functions (e.g., education) and policy categories (e.g., service provision) were identified, allowing the formulation of intervention components. Behavior change techniques (e.g., feedback on outcomes of a behavior) were selected to serve the intervention functions to deliver the desired change. This led to the conceptualization of an intervention plan., Results: The intervention "Prognosable" is presented. It consists of a stepwise working method (SWM) for evidence-based WDPE. The SWM offers an overview of important aspects (e.g., medical condition, clients' confidence in return-to-work) to consider in individual clients' WDPE. The SWM helps physicians to identify crucial functional limitations, find and appraise evidence-based information, weigh all relevant prognostic aspects and it supports physicians to conclude with an evidence-based WDPE, tailored to the individual client. The intervention "Prognosable" was designed, which also includes an educational program and a supportive software tool to enable implementation of the SWM., Conclusion: IM combined with BCW elements guided the development of a SWM for evidence-based WDPE. The SWM will be delivered through an educational program for physicians supported by a digital tool. The SWM, educational program and digital tool are ready to be implemented and evaluated in practice as the intervention "Prognosable.", Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Snoeck-Krygsman, Donker-Cools, Jansen, Hoving and Schaafsma.)

Introduction: The aim of this systematic review and meta-analysis was to assess factors associated with work participation in people with visual impairments and to explore how these factors may have changed over time., Method: A comprehensive search of PubMed, Embase.com, EBSCO/APA PsycInfo, EBSCO/CINAHL and EBSCO/ERIC from database inception to 1 April 2022 was performed. We included studies with cross-sectional design, case-control, case-series or cohort design, involving visually impaired working-age adults with at least moderate visual impairment, and evaluated the association between visual impairment and work participation. Studies involving participants with deaf-blindness or multiple disabilities were excluded. We assessed study quality (Newcastle-Ottawa Scale [NOS]), examined between-study heterogeneity and performed subgroup analyses. The study protocol was registered in PROSPERO, CRD42021241076., Results: Of 13,585 records, 57 articles described 55 studies including 1,326,091 participants from mostly high-income countries. Sociodemographic factors associated with employment included higher education (odds ratio [OR] 3.34, 95% confidence interval [CI] 2.47 to 4.51, I 2 0%), being male (OR 1.59, 95% CI 1.37 to 1.84, I 2 95%), having a partner (OR 1.73, 95% CI 1.12 to 2.67, I 2 34%), white ethnicity (OR 1.36, 95% CI 1.07 to 1.74, I 2 0%) and having financial assistance (OR 0.38, 95% CI 0.26 to 0.55, I 2 85%). Disease-related factors included worse visual impairment (OR 0.61, 95% CI 0.46 to 0.80, I 2 98%) or having additional disabilities (OR 0.55, 95% CI 0.49 to 0.62, I 2 16%). Intervention-related factors included mobility aid utilisation (OR 0.35, 95% CI 0.10 to 1.18, I 2 94%). A potential moderating effect of time period and geographical region was observed for some factors. Study quality (NOS) was rated moderate to high., Conclusion: Several sociodemographic and disease related factors were associated with employment status. However, the results should be interpreted with caution because of overall high heterogeneity. Future research should focus on the role of workplace factors, technological adjustments and vocational rehabilitation services on work participation., (© 2023 The Authors.

Background: Despite the adoption of minimally invasive techniques, recovery after abdominal surgery takes a long time. Electronic health (eHealth) modalities can provide guidance to patients, facilitating early return to normal activities. We aimed to assess the impact of a personalised eHealth programme on patients' return to normal activities after major abdominal surgery., Methods: This single-blind, randomised, placebo-controlled trial was done at 11 teaching hospitals in the Netherlands. Eligible participants were aged 18-75 years who underwent a laparoscopic or open colectomy or hysterectomy. An independent researcher randomly allocated participants (in a 1:1 ratio) to either the intervention or control group by use of computer-based randomisation lists, with stratification by sex, type of surgery, and hospital. Participants in the intervention group had access to a perioperative, personalised eHealth programme consisting of both standard face-to-face care and eHealth, that comprised interactive tools offering goal attainment and a personalised outcome measurement, which managed recovery expectations and provided postoperative guidance tailored to each patient. Patients were provided with an activity tracker and had access to a website and mobile app with an electronic consultation (eConsult) functionality. The control group received standard care and access to a placebo website containing recovery advice provided by the hospital. The primary outcome was the number of days between surgery and personalised return to normal activities, assessed with Kaplan-Meier curves. Intention-to-treat and per-protocol analyses were done with a Cox regression model. This trial is registered with the Netherlands National Trial Register (NTR5686)., Findings: Between Feb 11, 2016, and Aug 9, 2017, 355 participants were randomly assigned to the intervention (n=178) or control (n=177) groups. 342 participants were included in the intention-to-treat analysis. The median time until return to normal activities was 52 days (IQR 33-111) in the intervention group, and 65 days (39-152) in the control group (adjusted hazard ratio 1·30 [95% CI 1·03-1·64]; p=0·027). The frequency of postoperative complications did not differ between groups., Interpretation: This eHealth programme, delivering personalised care based on goal attainment scaling, enabled patients to return to their normal activities 13 days earlier than those who received standard care., Funding: ZonMw., Competing Interests: Declaration of interests CMdB, FGS, EvdM, HJB, JAFH, and JRA are the developers of the eHealth care programme under study.

Background: Instruments with sufficient diagnostic accuracy are better able to detect healthcare workers (HCWs) who are at risk of psychological distress. The objective of this review is to examine the diagnostic accuracy and measurement properties of psychological distress instruments in HCWs., Methods: We searched in Embase, Medline and PsycINFO from 2000 to February 2021. We included studies if they reported on the diagnostic accuracy of an instrument. To assess the methodological quality of the studies with regard to diagnostic accuracy, we used the Quality Assessment of Diagnostic Accuracy Studies and, for the measurement properties, the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN)., Results: Seventeen studies reporting on eight instruments were included. Overall, the methodological quality assessing the diagnostic accuracy and measurement properties was low, specifically for items addressing the domain 'index test'. The items addressing 'reference standard', 'time and flow' and 'patient selection' were mostly unclear. The criterion validity of the single-item burnout, the Burnout-Thriving Index, and the Physician Well-Being Index (PWBI) was sufficient, with area under the curve ranging from 0.75 to 0.92 and sensitivity 71-84%, respectively., Conclusion: Our findings indicate that it is questionable whether screening for HCWs at risk of psychological distress can be performed sufficiently with the included instruments due to the low numbers of studies per instrument and the low methodological quality.

Objective: Cooperation between clinical and occupational health care practitioners is a key aspect of clinical work-integrating care. This study aimed to gain insight into patients' experiences, needs, and expectations regarding cooperation between medical specialists and occupational health physicians., Methods: A thematic qualitative study was conducted involving a total of 33 participants in eight online focus groups., Results: Participants indicated practitioners are currently working in an isolated manner. However, participants desired for partnership between specialists and occupational health physicians to address work-related concerns and showed a need for explanation of the consequences of their diagnosis, so this can be translated into their ability to work., Conclusions: Currently, cooperation between clinical and occupational health care is lacking. Yet, some participants experienced that these disciplines could complement each other by working together to support patients in work participation., Competing Interests: Conflicts of interest: None declared., (Copyright © 2023 The Author(s).

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., (© 2022. The Author(s).)

Background: For working patients with a lower socioeconomic position, health complaints often result from a combination of problems on multiple life domains. To prevent long-term health complaints and absence from work, it is crucial for general and occupational health professionals to adopt a broad perspective on health and to collaborate when necessary. This study aimed to evaluate how the 'Grip on Health' intervention is implemented in general and occupational health practice to address multi-domain problems and to promote interprofessional collaboration., Method: A process evaluation was performed among 28 general and occupational health professionals, who were trained and implemented the Grip on Health intervention during a six-month period. The 'Measurement Instrument for Determinants of Innovations' was used to evaluate facilitators and barriers for implementing Grip on Health. Data included three group interviews with 17 professionals, a questionnaire and five individual interviews., Results: While most health professionals were enthusiastic about the Grip on Health intervention, its implementation was hindered by contextual factors. Barriers in the socio-political context consisted of legal rules and regulations around sickness and disability, professional protocols for interprofessional collaboration, and the Covid-19 pandemic. On the organizational level, lack of consultation time was the main barrier. Facilitators were found on the level of the intervention and the health professional. For instance, professionals described how the intervention supports addressing multi-domain problems and has created awareness of work in each other's healthcare domain. They recognized the relevance of the intervention for a broad target group and experienced benefits of its use. The intervention period was, nevertheless, too short to determine the outcomes of Grip on Health., Conclusion: The Grip on Health intervention can be used to address problems on multiple life domains and to stimulate interprofessional collaboration. Visualizing multi-domain problems appeared especially helpful to guide patients with a lower socioeconomic position, and a joint training of general and occupational health professionals promoted their mutual awareness and familiarity. For a wider implementation, stakeholders on all levels, including the government and professional associations, should reflect on ways to address contextual barriers to promote a broad perspective on health as well as on collaborative work., (© 2022.

Objective: This study tested and validated an existing tool for its ability to predict the risk of long-term (ie, ≥6 weeks) sickness absence (LTSA) after four days of sick-listing., Methods: A 9-item tool is completed online on the fourth day of sick-listing. The tool was tested in a sample (N=13 597) of food retail workers who reported sick between March and May 2017. It was validated in a new sample (N=104 698) of workers (83% retail) who reported sick between January 2020 and April 2021. LTSA risk predictions were calibrated with the Hosmer-Lemeshow (H-L) test; non-significant H-L P-values indicated adequate calibration. Discrimination between workers with and without LTSA was investigated with the area (AUC) under the receiver operating characteristic (ROC) curve., Results: The data of 2203 (16%) workers in the test sample and 14 226 (13%) workers in the validation sample was available for analysis. In the test sample, the tool together with age and sex predicted LTSA (H-L test P=0.59) and discriminated between workers with and without LTSA [AUC 0.85, 95% confidence interval (CI) 0.83-0.87]. In the validation sample, LTSA risk predictions were adequate (H-L test P=0.13) and discrimination was excellent (AUC 0.91, 95% CI 0.90-0.92). The ROC curve had an optimal cut-off at a predicted 36% LTSA risk, with sensitivity 0.85 and specificity 0.83., Conclusion: The existing 9-item tool can be used to invite sick-listed retail workers with a ≥36% LTSA risk for expedited consultations. Further studies are needed to determine LTSA cut-off risks for other economic sectors.

Purpose Health problems among employees with a lower socioeconomic position (SEP) often result from an interplay of problems on multiple life domains. Contextual factors greatly affect implementation of interventions that aim to solve these type of problems. The aim of this study was to gain insight into the organizational and socio-political context for implementation of preventive interventions that consider multiple life domains among employees with a lower SEP. Methods In total 16 semi-structured interviews were conducted with stakeholders at organizational level, occupational health service (OHS) level, and at socio-political macro level. Thematic analysis was performed to identify themes that describe the perceptions of stakeholders about the impact of contextual factors on implementation. Results The following themes were identified: (1) the importance of addressing problems on multiple life domains among employees with a lower SEP, (2) unclarity of responsibilities for solving problems on multiple life domains, (3) necessity of better collaboration between occupational and curative healthcare, (4) insufficient investments in prevention by employers, (5) difficulties in early identification of employees at risk for health problems, and (6) risk of conflicting role for supervisors in addressing problems on multiple life domains. Conclusions Implementation of preventive interventions considering multiple life domains among lower SEP employees is challenging, due to various contextual factors. To improve the feasibility, many different stakeholders both in- and outside occupational health practice need to be involved, collaborate, and need to be convinced of the added value to prevent problems on multiple life domains among employees with a lower SEP., (© 2021.

Purposes: Healthcare workers are at risk of stress-related disorders. Risk communication can be an effective preventive health measure for some health risks, but is not yet common in the prevention of stress-related disorders in an occupational healthcare setting. The overall aim is to examine whether risk communication was part of interventions aimed at the prevention of stress-related disorders in healthcare workers., Method: We performed a scoping review using the framework of Arksey and O'Malley. We searched in Medline, Web of Science and PsychInfo for studies reporting on preventive interventions of stress-related disorders in healthcare workers between 2005 and December 2020. Studies were included when the intervention reported on at least one element of risk communication and one goal. We predefined four elements of risk communication: risk perception, communication of early stress symptoms, risk factors and prevention; and three goals: inform, stimulate informed decision-making and motivate action., Results: We included 23 studies that described 17 interventions. None of the included interventions were primarily developed as risk communication interventions, but all addressed the goals. Two interventions used all four elements of risk communication. The prominent mode of delivery was face to face, mostly delivered by researchers. Early stress symptoms and risk factors were measured by surveys., Conclusions: Risk communication on risk factors and early signs of stress-related disorders is not that well studied and evaluated in an occupational healthcare setting. Overall, the content of the communication was not based on the risk perception of the healthcare workers, which limited the likelihood of them taking action., (© 2022. The Author(s).)

Objective: To evaluate a pilot implementation of an organizational-level intervention. The participatory approach (PA) was used to create a supportive work environment for employees with chronic conditions, with a key role for occupational physicians (OPs)., Methods: Twenty-eight semi-structured interviews were conducted with OPs and stakeholders within their organizations. Furthermore, observational data and research notes were gathered. Data analysis occurred through content analysis., Results: Recruitment of organizations was challenging, with a reach of 25%. Dose delivered, dose received, and fidelity differed across the three organizations. Organizations were positive about the PA as a method to improve support for employees with chronic conditions., Conclusions: The PA could be of added value for creating a supportive work environment. However, research is needed on activating organizations to improve support for employees with chronic conditions., Competing Interests: Conflict of interest: A.R.B, C.R.L.B., R.S., and F.G.S. declare that there is no conflict of interest. J.R.A. has no conflict of interest. His chair in Insurance Medicine is paid by the Dutch Social Security Agency. He is a stockholder and a senior consultant of Evalua Netherlands Ltd and consultant of IkHerstel., (Copyright © 2022 The Author(s).

Background: Individual Placement and Support (IPS) is an evidence-based, effective approach to help people with severe mental illness (SMI) obtain and maintain competitive employment. The aim of the present study was to examine employment outcomes and associations with an organizational and a financial factor in people with SMI who participated in Individual Placement and Support using a multifaceted implementation strategy (IPS + MIS). The goal of this strategy was to improve IPS implementation by enhancing collaboration among mental health care and vocational rehabilitation stakeholders, and realizing secured IPS funding., Methods: An observational cohort study including 103 participants was conducted, with a 30-month follow-up. Descriptive analyses were used to examine employment outcomes. Multivariable logistic and linear regression analyses were performed to study associations with an organizational and a financial factor: the level of experience of mental health agencies with providing IPS + MIS and the type of IPS funding (i.e. municipality funding (reference group) and the Dutch Social Security Institute: the Institute for Employee Benefits Schemes (UWV) funding)., Results: Forty-six percent of the participants were competitively employed at any time during the 30-month follow-up; the median number of days until competitive job obtainment and in competitive jobs was 201 and 265, respectively. The majority of all jobs obtained (81%) were categorized as 'elementary occupations', 'clerical support workers', and 'service and sales workers'. A higher level of experience of the mental health agencies with providing IPS + MIS was found to be positively associated with job obtainment (OR = 3.83, 95% CI 1.42-10.30, p = 0.01) and the number of days worked in competitive jobs (B = 1.21, 95% CI 0.36-2.07, p = 0.01). UWV funding was found to be negatively associated with job obtainment (OR = 0.30, 95% CI 0.11-0.77, p = 0.01). No association was found for the type of IPS funding and the number of days worked in competitive jobs (B = -0.73, 95% CI -1.48-0.02, p = 0.06)., Conclusions: This study shows that almost half of the people who participate in IPS + MIS obtain a competitive job within 30 months. The results further suggest that both the level of experience of mental health agencies with providing IPS + MIS, and funding may play a role in employment outcomes., (© 2022. The Author(s).)

Background: Assessing prognosis is challenging for many physicians in various medical fields. Research shows that physicians who perform disability assessments consider six areas when evaluating a prognosis: disease, treatment, course of the disease, external information, patient-related and physician-related aspects. We administered a questionnaire to evaluate how physicians rate the importance of these six prognosis areas during work disability evaluation and to explore what kind of support they would like during prognosis assessment., Methods: Seventy-six physicians scored the importance of 23 prognostic aspects distributed over six prognosis areas. Participants scored the importance of each aspect both "in general" and from the perspective of a case vignette of a worker with a severe degenerative disease. The questionnaire also covered needs and suggestions for support during the evaluation of prognoses., Results: Medical areas that are related to the disease, or the treatment or course of the disease, appeared important (scores of 7.0-9.0), with less differing opinions among participants (IQR 1.0-3.0). Corresponding verbatim remarks supported the importance of disease and treatment as prognostic aspects. In comparison, patient- and physician-related aspects scored somewhat lower, with more variability (range 4.0-8.0, with IQR 2.0-5.0 for patient- and physician-related considerations). Participants indicated a need for a tool or online database that includes prognostic aspects and prognostic evidence., Conclusions: Despite some variation in scores, the physicians rated all six prognosis areas as important for work disability evaluations. This study provides suggested aids to prognosis assessment, including an online support tool based on evidence-based medicine features., (© 2022. The Author(s).)

Background: To this date, there is little to no interprofessional collaboration between professionals in general and occupational health care in the Netherlands. Where earlier initiatives for improvement focused on general practitioners (GPs) and occupational physicians (OPs), we examine the role that professionals working under task delegation of GPs and OPs can play in addressing problems on multiple life domains as well as in interprofessional collaboration. Methods: We conducted three focus group interviews with 7 assistant practitioners (APs) in general practice, 11 practice nurses (PNs) in general practice and 8 APs in occupational health practice. Results: All PNs and APs in our study are confronted with multi-domain problems and see a role for themselves in addressing these problems. Moreover, in case of multi-domain problems, they acknowledge the relevance of interprofessional collaboration to provide good care. At this moment, however, there is practically no collaboration at the level of PNs and APs. Challenges are found in the formal task delegation and role identity of the APs in occupational health practice, unfamiliarity and prejudices among especially general practice PNs and APs regarding occupational health care, and practical barriers as privacy laws and reachability. Conclusion: Interprofessional collaboration among PNs and APs in general and occupational health care is possible, provided that a solution is found for fundamental and practical challenges. Potential solutions are to shift the focus from sharing medical information to communicating about the needs of working patients to function healthily on multiple life domains, to address interprofessional collaboration in educations, to adapt consultation protocols to include work and to organize joint meetings between professionals in general and occupational health practice. Finally, addressing structural barriers such as privacy laws and financing requires political action., (© The Author(s) 2022.)

Background: To limit students' medical absenteeism and premature school dropout in the Netherlands, the Medical Advice for Sick-reported Students (MASS) intervention was developed to enhance collaboration between students, parents, school, and health care professionals. MASS reduces medical absenteeism. However, it does not yet optimally support professionals in monitoring students nor automatically stimulating students' autonomy regarding their situation., Objective: This study aimed to identify professionals' and students' perceived need for an online supportive application to monitor and reduce absenteeism and stimulate student autonomy and school reintegration., Methods: Concept mapping sessions were held with professionals (n=23) and secondary school students (n=27) in group meetings or online to identify their perspectives and needs. Multidimensional scaling and hierarchical clustering were done with Ariadne 3.0 software. The resulting concept maps were reclustered and interpreted by 4 researchers., Results: Three heterogeneous groups of professionals generated 17 clusters (135 unique statements), with a mean importance rating ranging from 2.9 to 4.6 on a Likert scale with scores ranging from 1 to 5. Three heterogeneous groups of secondary school students generated 18 clusters (95 unique statements), with a mean importance rating ranging from 3.2 to 4.6. Professionals considered as most important the following: easily accessible contact with students; supporting, motivating, and rewarding students; monitoring absent students; providing information to students and their parents; exchanging information between professionals. Students considered as most important the following: better teacher-student communication and respect; communication between school professionals on the one hand and parents, other professionals, and students on the other hand; guidance in missed learning materials and tests. Students perceived an online format for support as the obvious option., Conclusions: Both professionals and students were positive about an online application to support students in dealing with medical absenteeism, especially considering the need for better and easily accessible contact between students and professionals. An eHealth or mobile health (mHealth) application addressing these aspects could stimulate student autonomy and have positive effects on medical absenteeism., (©Mariette H H Hoogsteder, Linda N Douma, Charlotte G A Eskens, Renske L Berendsen, Yvonne T M Vanneste, Frederieke G Schaafsma.

Objective: To perform a European survey of the evidence needs and training demands of insurance medicine professionals related to professional tasks and evidence-based practice., Design: International survey., Subjects: Professionals working in insurance medicine., Methods: Experts designed an online questionnaire including 26 questions related to 4 themes: evidence needs; training demands; evidence-seeking behaviour; and attitudes towards evidence-based medicine. Descriptive statistics were presented by country/conference and the total sample., Results: A total of 782 participants responded. Three-quarter of participants experienced evidence needs at least once a week, related to mental disorders (79%), musculoskeletal disorders (67%) and occupational health (65%). Guidelines (76%) and systematic reviews (60%) were the preferred types of evidence and were requested for assessment of work capacity (64%) and prognosis of return-to-work (51%). Evidence-based medicine was thought to facilitate decision-making in insurance medicine (95%). Fifty-two percent of participants felt comfortable finding, reading, interpreting, and applying evidence. Countries expressed similar needs for reviews on typical topics., Conclusion: This study reveals evidence gaps in key areas of insurance medicine, supporting the need for further research, guidelines and training in evidence-based insurance medicine. Importantly, insurance medicine professionals should recognize that evidence-based practice is crucial in producing high-quality assessments.

Background: Individual Placement and Support (IPS) is an evidence-based, effective approach to help people with severe mental illness (SMI) achieve competitive employment. The aim of the present study is to explore experiences with Individual Placement and Support using a multifaceted implementation strategy (IPS + MIS), and competitive employment. The goal of this strategy was to improve IPS implementation by enhancing collaboration between mental health care and vocational rehabilitation stakeholders, and realizing a secured IPS funding with a 'pay for performance' element., Methods: A qualitative, exploratory study was performed using semi-structured interviews with IPS clients (n = 10) and two focus groups with IPS employment specialists (n = 7 and n = 8) to collect rich information about their experiences with IPS + MIS and competitive employment. Thematic content analysis was used to analyse the data., Results: Themes related to experiences with IPS and the multifaceted implementation strategy were identified, including the importance of discussing the client's motivation and motives to work, facilitators and barriers to obtaining and maintaining employment, facilitators to collaboration between stakeholders, barriers to benefits counselling, organizational barriers to IPS execution and collaboration between stakeholders, financial barriers to IPS execution and experiences with the pay for performance element., Conclusions: Although the multifaceted implementation strategy seems to contribute to an improved IPS implementation, the barriers identified in this study suggest that further steps are necessary to promote IPS execution and to help people with SMI obtain and maintain competitive employment.

Background: Supporting employees with chronic conditions can prevent work-related problems and facilitate sustainable employment. Various stakeholders are involved in providing support to these employees. Understanding their current practices and experienced barriers is useful for the development of an organizational-level intervention to improve this support. The aim of this study was to explore the current practices of occupational physicians and organizational representatives, identifying both barriers to providing support and opportunities for improvement., Methods: Two focus groups with sixteen occupational physicians and seven semi-structured interviews with organizational representatives were held between January and June 2018. Data was analyzed using thematic content analysis., Results: Several barriers to offer support were identified, including barriers at the organizational level (negative organizational attitudes towards employees with chronic conditions), the employee level (employees' reluctance to collaborate with employers in dealing with work-related problems), and in the collaboration between occupational physicians and organizational representatives. In addition, barriers in occupational health care were described, e.g. occupational physicians' lack of visibility and a lack of utilization of occupational physicians' support. Opportunities to optimize support included a shared responsibility of all stakeholders involved, actively anchoring prevention of work-related problems in policy and practice and a more pronounced role of the health care sector in preventing work-related problems., Conclusions: Preventing work-related problems for employees with chronic conditions can be achieved by addressing the identified barriers to provide support. In addition, both occupational physicians and organizational representatives should initiate and secure preventive support at the organizational level and in occupational health care. These insights are helpful in developing an intervention aimed at supporting employees with chronic conditions to stay at work.

Objectives: Workplace-based selective prevention of mental health problems currently relies on subjective evaluation of stress complaints. Hair cortisol captures chronic stress responses and could be a promising biomarker for the early identification of mental health problems. The objective was to provide an overview of the state-of-the-art knowledge on the practical value of hair cortisol in the occupational setting., Methods: We performed a scoping review of cross-sectional and longitudinal studies in PubMed, Embase, and PsycINFO up to November 2019 assessing the relations of hair cortisol with work-related stressors, perceived stress, and mental health outcomes in healthy workers., Results: We found five longitudinal studies, of which two observed an increase in work-related stressors to be associated with higher hair cortisol, one found a relation with lower hair cortisol and one did not find a relationship. Findings of cross-sectional studies were also mixed. The one available longitudinal study regarding mental health showed that hair cortisol was not related to depressive symptoms., Conclusions: Hair cortisol measurement within occupational health research is still in its early stage and more longitudinal studies are urgently needed to clarify its relationship with work-related stressors and perceived stress before hair cortisol can be used to identify workers at risk for mental health problems., (© 2021 The Authors.

Purpose This study describes the development of an evidence-based intervention to create a supportive work environment for employees with chronic conditions. Occupational physicians (OPs) play an important role in guiding organizations in this process of organizational change. Supportive work environments can aid in preventing work-related problems and facilitate sustainable employment. Current workplace interventions for employees with chronic conditions are mainly focused on return to work or a reduction in sick leave at the individual worker's level. This study contributes to the literature an organizational-level intervention which utilizes a preventive approach. Methods Intervention mapping (IM) is a six-step, structured protocol that was used to develop this intervention. In step 1, a needs assessment was conducted to define the problem and explore the perspectives of all stakeholders involved. The program outcomes and the performance objectives of employees with chronic conditions and occupational physicians were specified in step 2. In step 3, appropriate methods and practical applications were chosen. Step 4 describes the actual development of the intervention, consisting of (1) a training for occupational physicians to teach them how to guide organizations in creating a supportive work environment; (2) a practical assignment; and (3) a follow-up meeting. The intervention will be implemented in a pilot study in which occupational physicians will put their acquired knowledge and skills into practice within one of their organizations, which is delineated in step 5. Conclusions IM proved to be a valuable and practical tool for the development of this intervention, aiming to facilitate sustainable employment for employees with chronic conditions.

Background: Workers with a low socioeconomic position (SEP) have a higher risk for health problems and premature dropout from the workforce. Unfavorable working conditions and unhealthy behaviors are more prevalent among this group of workers. The Participatory Approach (PA), is an evidence-based method to identify and solve problems at the workplace related to health issues of the worker. Health problems among workers with a low SEP are usually caused by an interplay of problems in and outside the workplace. To solve health problems on multiple life domains for workers with a low SEP we aim to adapt this approach to a broader perspective., Methods: An Intervention Mapping (IM) protocol was used to adapt the PA. First, a needs assessment was conducted combining literature with data from interviews and focus groups with workers with a low SEP, employers and occupational health professionals (OHPs). Based on the needs assessment a program goal and performance and change objectives were defined, which resulted in methods and practical strategies to solve problems on multiple life domains. Based on the results of these steps, the PA was adapted and an implementation and evaluation plan were developed., Results: The needs assessment confirmed that an interplay of problems on multiple life domains affect work functioning and health of workers with a low SEP. Moreover, they perceived difficulties with solving problems or used passive or avoidant coping styles towards these problems. The program goal is to identify and solve problems on multiple life domains that affect healthy functioning at work. To achieve this workers need support from OHPs to solve problems. The PA protocol and materials were adapted using theoretical concepts of the Self-Determination Theory (SDT), which resulted in the Grip on Health intervention. For OHPs a training was developed on how to implement this intervention in practice. The intervention will be evaluated in a pilot implementation study among workers with a low SEP and other relevant stakeholders., Conclusions: IM was a valuable tool for the adaptation of the PA to better support workers with a low SEP to improve their work functioning and health from a broader perspective.

Aims: To obtain more insight into differences in sick leave assessments of workers with subjective health complaints, we studied sick leave assessments among Dutch occupational and insurance physicians, and explored possible determinants for these differences. Methods: A cross-sectional study was conducted among 50 occupational and 43 insurance physicians in the Netherlands. They all assessed sick leave (complete, partial or no) of nine video case vignettes of workers with subjective health complaints and gave their opinion on the complaints, sick leave and health status. Data were analyzed via a multinomial regression approach, using generalized estimating equations in SPSS. Results: Compared to occupational physicians, complete sick leave was less likely to be assessed by insurance physicians (odds ratio 0.74, 95% confidence interval 0.56-0.97). For occupational physicians, psychological diagnoses, private issues and reduced work ability had more influence on the outcome of the sick leave assessment than for insurance physicians. Conclusion: There are differences in sick leave assessments for workers with subjective health complaints between physicians working in the same occupational health system; insurance physicians are stricter in assessing complete sick leave than occupational physicians. These differences may be explained by differences in roles, tasks and perspectives of the physician in occupational health care.Implications for Rehabilitation  Sick leave assessments of workers with subjective health complaints.  • The current study showed that there are differences between occupational physicians and insurance physicians in sick leave assessments for workers with subjective health complaints.  • These differences may be based on different perspectives, roles and tasks of physicians.  • Physicians working in the rehabilitation and occupational health system should be more aware of the impact of these differences on their assessments and advices.  • Better communication and collaboration between physicians, and more insight into and clarification of the perspectives may result in more agreement between physicians' sick leave assessment and advice towards workers.

Objectives Weighted regression procedures can be an efficient solution for cohort studies that involve rare events or diseases, which can be difficult to predict, allowing for more accurate prediction of cases of interest. The aims of this study were to (i) predict changes in work ability at one year after approval of the work disability benefit and (ii) explore whether weighted regression procedures could improve the accuracy of predicting claimants with the highest probability of experiencing a relevant change in work ability. Methods The study population consisted of 944 individuals who were granted a work disability benefit. Self-reported questionnaire data measured at baseline were linked with administrative data from Dutch Social Security Institute databases. Standard and weighted multinomial logit models were fitted to predict changes in the work ability score (WAS) at one-year follow-up. McNemar's test was used to assess the difference between these models. Results A total of 208 (22%) claimants experienced an improvement in WAS. The standard multinomial logit model predicted a relevant improvement in WAS for only 9% of the claimants [positive predictive value (PPV) 62%]. The weighted model predicted significantly more cases, 14% (PPV 63%). Predictive variables were several physical and mental functioning factors, work status, wage loss, and WAS at baseline. Conclusion This study showed that there are indications that weighted regression procedures can correctly identify more individuals who experience a relevant change in WAS compared to standard multinomial logit models. Our findings suggest that weighted analysis could be an effective method in epidemiology when predicting rare events or diseases.

Background: Working with a chronic condition can be challenging. Providing support to workers with a chronic condition can help them to stay at work and prevent work-related problems. Workers with a chronic condition who successfully stay at work can provide valuable input for the development of effective supportive interventions to prevent exit from work and facilitate sustainable employment. The aim of this study is to explore the lived experiences of workers with a chronic condition and identify existing barriers, facilitators and possible support needs for staying at work., Methods: Four focus groups were conducted between August and December 2017 with workers with one or more chronic conditions (n = 30). Participants included employees and (partially) self-employed workers. All focus group data were transcribed verbatim and thematically analyzed., Results: Disclosure and expressing one's needs were considered important personal facilitators for staying at work. Environmental facilitators included receiving practical information on working with a chronic condition and social and employer support. Environmental barriers were identified in the work environment, the health care system and service provision, e.g., manager and co-worker's lack of knowledge about working with a chronic condition, a lack of focus on work in the course of treatment for a chronic condition, dissatisfaction with occupational physician support, and the absence of support for self-employed workers. Provided support should be available to all workers, and be proactive and tailored to the workers' specific support needs., Conclusions: A variety of facilitators, barriers and support needs were identified in various domains. By addressing environmental barriers (e.g., by integrating work in the course of treatment and creating supportive work environments), sustainable employment by workers with a chronic condition can be promoted.

Background: Entrepreneurs may have to deal with different psychosocial risk factors than employees. Understanding relevant psychosocial risk factors for entrepreneurs is important for occupational health practice to develop effective measures to prevent work disability. This knowledge will be used to adjust the Work and Wellbeing Inventory an existing screening tool for employees., Objective: The aim was to explore psychosocial risk factors and relevant personality traits to adjust and further develop the Work and Wellbeing Inventory to predict work disability for entrepreneurs., Methods: In a qualitative explorative study, we interviewed 17 entrepreneurs varying in type of business and demographic background. By semi-structured face-to-face interviews, we explored their experiences with psychosocial risk factors related to entrepreneurship. Transcripts were analyzed by qualitatively coding procedures and constant comparative methods., Results: According to these entrepreneurs financial insecurity, conflict of interest, large responsibility, high number of working hours, managing tasks, and administrative burden were the major themes they had to deal with. Relevant personality traits for successful entrepreneurship were stress resistance, being all round, flexible, a good communicator, good leadership, and being able to set limits., Conclusions: The results of this study are relevant for occupational health practice focusing on the wellbeing of entrepreneurs, and will be used to adjust items in the Work and Wellbeing Inventory.

Background: The increase in prevalence of colorectal cancer among young patients coupled with an older retirement age in developed countries means that more patients are being diagnosed with colorectal cancer while still at work. The aim of this study was to develop prediction models for return to work by 1 and 2 years after the start of sick leave., Methods: This was a retrospective registry-based cohort study of data from a nationwide occupational health service in the Netherlands. Only employed patients with colonic or rectal cancer treated with curative intent were included. Two predictor variable models were developed using multivariable logistic regression with backward selection. Calibration, discrimination and explained variance were used to assess model performance, and internal validation by bootstrapping was performed., Results: Median time to return to work for 317 included patients was 423 (95 per cent c.i. 379 to 467) days. Two-thirds of patients had returned to work by 2 years after the start of the sick leave. Presence of metastases, adjuvant treatment, stoma, emotional distress and postoperative complications were predictors of not returning to work in the 1-year model. In the 2-year model, presence of metastases, emotional distress, postoperative complications, company size and the trajectory of the return-to-work process were predictors., Conclusion: Almost 70 per cent of patients with colorectal cancer in this population returned to work within 2 years after the start of sick leave. The models can be used to guide patients early in colorectal cancer treatment about the likelihood of returning to work, and to identify and modify barriers that could facilitate this., (© 2019 The Authors.

Purpose To study associations between the level of self-reported work motivation and employment outcomes in people with severe mental illness (SMI) enrolled in a vocational rehabilitation program. Methods Data of 151 study participants, collected from a randomised controlled trial with a 30-month follow-up period, were used for a secondary data analysis. Multiple logistic regression, linear regression and cox regression analyses were performed to analyse the association between the level of work motivation at baseline and job obtainment, duration of job, and time until job obtainment during the 30-month follow-up period. Results No statistically significant associations were found between the level of work motivation and job obtainment (OR 1.83, 95% CI 0.55-6.06, p = 0.32), job duration (B = - 0.74, 95% CI - 2.37 to 0.89, p = 0.37, R-squared = 0.03), or time until job obtainment (HR = 1.53, 95% CI 0.64-3.68, p = 0.34). Conclusions The results of this study show no statistically significant associations between the level of work motivation and employment outcomes in people with SMI enrolled in a vocational rehabilitation program. These associations may be underestimated due to range restriction of the work motivation's level. Further research is recommended to increase knowledge on the associations between work motivation and employment outcomes, as it could be relevant for further understanding success in vocational rehabilitation.

Objective: Our purpose was to obtain information about the correlation between workers' self-perceived health and physician-assessed functional limitations. We also studied whether this correlation differed between workers with subjective health complaints that cannot (SHC) and those that can be explained (non-SHC) by a well-defined medical disease., Methods: Baseline data of 2040 participants from a prospective cohort study were used for this study. These participants answered a questionnaire on their self-perceived health and received a medical work disability assessment during which physicians reported functional limitations. Pearson correlation analyses were used to calculate correlations between 4 functional limitation factors and 11 self-perceived health factors. For correlations with coefficients ≥0.30, linear regression analyses were performed to assess possible differences between participants with SHC (n = 363) and those with non-SHC (n = 1677)., Results: We found correlations ≥0.30 between two functional limitation factors and six self-perceived health factors for all participants. SHC participants showed lower correlations than the non-SHC participants between the physical functional limitation and the SF-36 self-perceived physical health factors (-0.49, 95% CI -0.56 to -0.41 vs. -0.60, 95% CI -0.62 to -0.57) and between the mental functional limitation and the SF-36 self-perceived mental health factors (-0.30, 95% CI -0.39 to -0.20 vs. -0.40, 95% CI -0.44 to -0.36)., Conclusion: Self-perceived health showed overall low to moderate correlations with physician-assessed functional limitations. Some of these correlations were lower for workers with SHC than for those with non-SHC. This may indicate that physicians rely slightly more on well-defined medical complaints within medical work disability assessments., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Support for guiding and monitoring postoperative recovery and resumption of activities is usually not provided to patients after discharge from the hospital. Therefore, a perioperative electronic health (eHealth) intervention ("ikherstel" intervention or "I recover" intervention) was developed to empower gynecological patients during the perioperative period. This eHealth intervention requires a need for further development for patients who will undergo various types of general surgical and gynecological procedures., Objective: This study aimed to further develop the "ikherstel" eHealth intervention using Intervention Mapping (IM) to fit a broader patient population., Methods: The IM protocol was used to guide further development of the "ikherstel" intervention. First, patients' needs were identified using (1) the information of a process evaluation of the earlier performed "ikherstel" study, (2) a review of the literature, (3) a survey study, and (4) focus group discussions (FGDs) among stakeholders. Next, program outcomes and change objectives were defined. Third, behavior change theories and practical tools were selected for the intervention program. Finally, an implementation and evaluation plan was developed., Results: The outcome for an eHealth intervention tool for patients recovering from abdominal general surgical and gynecological procedures was redefined as "achieving earlier recovery including return to normal activities and work." The Attitude-Social Influence-Self-Efficacy model was used as a theoretical framework to transform personal and external determinants into change objectives of personal behavior. The knowledge gathered by needs assessment and using the theoretical framework in the preparatory steps of the IM protocol resulted in additional tools. A mobile app, an activity tracker, and an electronic consultation (eConsult) will be incorporated in the further developed eHealth intervention. This intervention will be evaluated in a multicenter, single-blinded randomized controlled trial with 18 departments in 11 participating hospitals in the Netherlands., Conclusions: The intervention is extended to patients undergoing general surgical procedures and for malignant indications. New intervention tools such as a mobile app, an activity tracker, and an eConsult were developed., Trial Registration: Netherlands Trial Registry NTR5686; http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=5686., (©Chantal M den Bakker, Frederieke G Schaafsma, Eva van der Meij, Wilhelmus JHJ Meijerink, Baukje van den Heuvel, Astrid H Baan, Paul HP Davids, Petrus C Scholten, Suzan van der Meij, W Marchien van Baal, Annette D van Dalsen, Daniel J Lips, Jan Willem van der Steeg, Wouter KG Leclercq, Peggy MAJ Geomini, Esther CJ Consten, Steven E Schraffordt Koops, Steve MM de Castro, Paul JM van Kesteren, Huib A Cense, Hein BAC Stockmann, A Dorien ten Cate, Hendrik J Bonjer, Judith AF Huirne, Johannes R Anema.

Background: Long-term recovery takes longer than expected despite improved surgical techniques and Enhanced Recovery After Surgery programs. An electronic health (eHealth) care program ("ikherstel") was developed to partially substitute perioperative care for patients undergoing colorectal surgical procedures. Successfully tested eHealth programs are not always implemented in usual care, and it is, therefore, important to evaluate the process to optimize future implementation., Objective: The aim of this study was to evaluate whether the eHealth intervention was executed as planned., Methods: A mixed-methods process evaluation was carried out alongside a multicenter randomized controlled trial (RCT). This evaluation was performed using the Linnan and Steckler framework for the quantitative part of this study, measuring the components reach, dose delivered, dose received, fidelity, and participants' attitudes. Total implementation scores were calculated using the averaging approach, in which the sum of all data points is divided by the number of data points and the total adherence to the protocol is measured. For the qualitative part, the Unified Theory of Acceptance and Use of Technology framework was used. The quantitative data were based on participants' questionnaires, a logistic database, a weblog, and participants' medical files and were obtained by performing semistructured interviews with participants of the RCT., Results: A total of 151 participants of 340 eligible patients were included in the RCT, of which 73 participants were allocated to the intervention group. On the basis of the quantitative process data, total implementation scores for the website, mobile app, electronic consult, and activity tracker were 64%, 63%, 44%, and 67%, respectively. Participants in the qualitative part experienced the program as supportive and provided guidance on their recovery process after colorectal surgery. Most frequently mentioned barriers were the limited interaction with and feedback from health care professionals and the lack of tailoring of the convalescence plan in case of a different course of recovery., Conclusions: The intervention needs more interaction with and feedback from health care professionals and needs more tailored guidance in case of different recovery or treatment courses. To ensure a successful implementation of the program in daily practice, some adjustments are required to optimize the program in a blended care form., Trial Registration: Netherlands Trial Registry NTR5686; http://www.trialregister.nl/trialreg/admin/rctview.asp?TC= 5686 (Archieved by WebCite at http://www.webcitation.org/75LrJaHrr)., (©Chantal M den Bakker, Judith AF Huirne, Frederieke G Schaafsma, Charlotte de Geus, Hendrik J Bonjer, Johannes R Anema.

Background: More colon cancer patients are expected to fully recover after treatment due to earlier detection of cancer and improvements in general health- and cancer care. The objective of this study was to gather participants' experiences with full recovery in the different treatment phases of multimodal treatment and to identify their needs during these phases. The second aim was to propose and evaluate possible solutions for unmet needs by the introduction of eHealth., Methods: A qualitative study based on two focus group discussions with 22 participants was performed. The validated Supportive Care Needs Survey and the Cancer Treatment Survey were used to form the topic list. The verbatim transcripts were analyzed with Atlas.ti. 7th version comprising open, axial and selective coding. The guidelines of the consolidated criteria for reporting qualitative research (COREQ) were used., Results: Experiences with the treatment for colon cancer were in general positive. Most important unmet needs were 'receiving information about the total duration of side effects', 'receiving information about the minimum amount of chemo needed to overall survival' and 'receiving a longer aftercare period (with additional attention for psychological guidance)'. More provision of information online, a chat function with the oncological nurse specialist via a website, and access to scientific articles regarding the optimal dose of chemotherapy were often mentioned as worthwhile additions to the current health care for colon cancer., Conclusions: Many of the unmet needs of colon cancer survivors occur during the adjuvant treatment phase and thereafter. To further optimize recovery and cancer care, it is necessary to have more focus on these unmet needs. More attention for identifying patients' problems and side-effects during chemotherapy; and identifying patients' supportive care needs after finishing chemotherapy are necessary. For some of these needs, eHealth in the form of blended care will be a possible solution.

Background: Colorectal cancer is diagnosed progressively in employed patients due to screening programs and increasing retirement age. The objective of this study was to identify prognostic factors for return to work and work disability in patients with colorectal cancer., Methods: The research protocol was published at PROSPERO with registration number CRD42017049757. A systematic review of cohort and case-control studies in colorectal cancer patients above 18 years, who were employed when diagnosed, and who had a surgical resection with curative intent were included. The primary outcome was return to work or work disability. Potentially prognostic factors were included in the analysis if they were measured in at least three studies. Risk of bias was assessed according to the QUality In Prognosis Studies tool. A qualitative synthesis analysis was performed due to heterogeneity between studies. Quality of evidence was evaluated according to Grading of Recommendation Assessment, Development and Evaluation., Results: Eight studies were included with a follow-up period of 26 up to 520 weeks. (Neo)adjuvant therapy, higher age, and more comorbidities had a significant negative influence on return to work. A previous period of unemployment, extensive surgical resection and postoperative complications significantly increased the risk of work disability. The quality of evidence for these prognostic factors was considered very low to moderate., Conclusion: Health care professionals need to be aware of these prognostic factors to select patients eligible for timely intensified rehabilitation in order to optimize the return to work process and prevent work disability., Competing Interests: CdB, AZ, HdV, LS, EA, MA, HB, AdB and FS have no conflicts of interest.

Background: Instructing and guiding patients after surgery is essential for successful recovery. However, the time that health-care professionals can spend with their patients postoperatively has been reduced because of efficiency-driven, shortened hospital stays. We evaluated the effect of a personalised e-health-care programme on return to normal activities after surgery., Methods: A multicentre, single-blind, randomised controlled trial was done at seven teaching hospitals in the Netherlands. Patients aged 18-75 years who were scheduled for laparoscopic cholecystectomy, inguinal hernia surgery, or laparoscopic adnexal surgery for a benign indication were recruited. An independent researcher randomly allocated participants to either the intervention or control group using computer-based randomisation lists, with stratification by sex, type of surgery, and hospital. Participants in the intervention group had access to a perioperative, personalised, e-health-care programme, which managed recovery expectations and provided postoperative guidance tailored to the patient. The control group received usual care and access to a placebo website containing standard general recovery advice. Participants were unaware of the study hypothesis and were asked to complete questionnaires at five timepoints during the 6-month period after surgery. The primary outcome was time between surgery and return to normal activities, measured using personalised patient-reported outcome measures. Intention-to-treat and per-protocol analyses were done. This trial is registered in the Netherlands National Trial Register, number NTR4699., Findings: Between Aug 24, 2015, and Aug 12, 2016, 344 participants were enrolled and randomly allocated to either the intervention (n=173) or control (n=171) group. 14 participants (4%) were lost to follow-up, with 330 participants included in the primary outcome analysis. Median time until return to normal activities was 21 days (95% CI 17-25) in the intervention group and 26 days (20-32) in the control group (hazard ratio 1·38, 95% CI 1·09-1·73; p=0·007). Complications did not differ between groups., Interpretation: A personalised e-health intervention after abdominal surgery speeds up the return to normal activities compared with usual care. Implementation of this e-health programme is recommended in patients undergoing intermediate-grade abdominal, gynaecological, or general surgical procedures., Funding: ZonMw., (Copyright © 2018 Elsevier Ltd.

Purpose The purpose of this study is to measure the psychometric properties of the Work and Wellbeing Inventory (WBI) (in Dutch: VAR-2), a screening tool that is used within occupational health care and rehabilitation. Our research question focused on the reliability and validity of this inventory. Methods Over the years seven different samples of workers, patients and sick listed workers varying in size between 89 and 912 participants (total: 2514), were used to measure the test-retest reliability, the internal consistency, the construct and concurrent validity, and the criterion and predictive validity. Results The 13 scales displayed good internal consistency and test-retest reliability. The constructive validity of the WBI could clearly be demonstrated in both patients and healthy workers. Confirmative factor analyses revealed a CFI >.90 for all scales. The depression scale predicted future work absenteeism (>6 weeks) because of a common mental disorder in healthy workers. The job strain scale and the illness behavior scale predicted long term absenteeism (>3 months) in workers with short-term absenteeism. The illness behavior scale moderately predicted return to work in rehab patients attending an intensive multidisciplinary program. Conclusions The WBI is a valid and reliable tool for occupational health practitioners to screen for risk factors for prolonged or future sickness absence. With this tool they will have reliable indications for further advice and interventions to restore the work ability.

Background: Individual Placement and Support (IPS) is an evidence-based approach to help people with severe mental illness achieve competitive employment. This article provides insight into an organizational and a financial implementation strategy for IPS in the Netherlands by exploring the perceived facilitators and barriers among participating stakeholders. The goal of this multifaceted strategy was to improve IPS implementation by improving the collaboration between all organizations involved, and realising secured IPS funding with a 'pay for performance' element., Methods: A qualitative, explorative study among practitioners (n = 8) and decision makers (n = 7) in mental health care and vocational rehabilitation was performed using semi-structured interviews to collect rich information about the possible facilitators and barriers with regard to the organizational and financial implementation strategy for IPS., Results: Important perceived facilitators were the key principles of the IPS model, regular meetings of stakeholders in mental health care and vocational rehabilitation, stakeholders' experienced ownership of IPS and collaboration, the mandate and influence of the decision makers involved and secured IPS funding. Important perceived barriers included the experienced rigidity of the IPS model fidelity scale and lack of independent fidelity reviewers, the temporary and fragmented character of the secured funding, lack of communication between decision makers and practitioners and negative attitudes and beliefs among mental health clinicians. Changes in legislation were experienced as a facilitator as well as a barrier., Conclusions: The results of this study suggest that the collaboration and IPS funding were experienced as improved by applying an organizational and a financial implementation strategy. However, considerable effort is still necessary to overcome the remaining barriers identified and to make the implementation of IPS a success in practice.

Background: To improve patient care, and to reduce unnecessary referrals for diagnostic imaging and medical specialist care for low back pain, an evidence-based guideline for low back pain was developed in the Netherlands in 2010. The current study evaluated the effect of a multifaceted implementation strategy on guideline adherence among Dutch general practitioners., Methods: The implementation strategy included a multidisciplinary training, provision of educational material and an interactive website for healthcare professionals, supported by a multimedia eHealth intervention for patients with low back pain. Adherence was measured using performance indicators based on 3 months data extracted from the contacts with patients with low back pain recorded in the electronic medical records of participating general practitioners. Performance indicators were compared between two groups: a usual care group and an implementation group. Performance indicators were referrals to consultations with medical specialists, to diagnostic imaging, and to psychosocial and/or occupational physician consultations, and inquiries about psychosocial and occupational risk factors., Results: The electronic medical records of 5130 patient contacts for LBP were analysed; 2453 patient contacts in the usual care group and 2677 patient contacts in the implementation group. Overall, rates of referral and of recorded inquiries regarding psychosocial and occupational risk factors remained low in both groups over time. The only statistically significant difference found was a reduction in the number of referrals to neurologists in the implementation group (from 100 (7%) to 50 (4%)) compared to the usual care group (from 48 (4%) to 50 (4%), (p < 0.01)). There were no other between-group differences in referrals., Conclusion: In the short term, the strategy did not result in improved guideline adherence among general practitioners, and it is not recommended for widespread use. However, baseline referral rates in participating practices were already low, possibly leaving only little room for improvement. Inquiries for psychosocial and occupational risk factors remained low and this leaves room for improvement., Trial Registration: This trial is registered in the Netherlands Trial Register (NTR): NTR4329 . Registration date: December 20th, 2013.

Objective: To evaluate the implementation and effectiveness of an internet-based perioperative care programme for patients following gynaecological surgery for benign disease., Design: Stepped-wedge cluster randomised controlled trial., Setting: Secondary care, nine hospitals in the Netherlands, 2011-2014., Participants: 433 employed women aged 18-65 years scheduled for hysterectomy and/or laparoscopic adnexal surgery., Interventions: An internet-based care programme was sequentially rolled out using a multifaceted implementation strategy. Depending on the implementation phase of their hospital, patients were allocated to usual care (n=206) or the care programme (n=227). The care programme included an e-health intervention equipping patients with tailored personalised convalescence advice., Main Outcome Measures: The primary outcome was duration until full sustainable return to work (RTW). The degree of implementation of the care programme was evaluated at the level of the patient, healthcare provider and organisation by indicators measuring internet-based actions by patients and providers., Results: Median time until RTW was 49 days (IQR 27-76) in the intervention group and 62 days (42-85) in the control group. A piecewise Cox model was fitted to take into account non-proportionality of hazards. In the first 85 days after surgery, patients receiving the intervention returned to work faster than patients in the control group (HR 2.66, 95% CI 1.88 to 3.77), but this effect was reversed in the small group of patients that did not reach RTW within this period (0.28, 0.17 to 0.46). Indicators showed that the implementation of the care programme was most successful at the level of the patient (82.8%) and professional (81.7%)., Conclusions: Implementation of an internet-based care programme has a large potential to lead to accelerated recovery and improved RTW rates following different types of gynaecological surgeries., Trial Registration Number: NTR2933; Results., Competing Interests: Competing interests: JRA reports a chair in insurance medicine paid by the Dutch Social Security Agency, and he is a stockholder of Evalua.
