RESUMEN
BACKGROUND: Over 50% of adults with visual impairment experience severe fatigue. Therefore, we developed a guided E-health intervention based on cognitive behavioral therapy and self-management to reduce fatigue in this population. This pilot study evaluated the usability, feasibility, fidelity and potential effectiveness of E-nergEYEze. METHODS: E-nergEYEze was developed by a design team and customized by conducting a pilot study using an iterative development strategy. The intervention was first tested in a usability study among adults with visual impairment (n = 5). Participants were asked to think-aloud while exploring the intervention features and a semi-structured interview was performed afterwards. Subsequently, the enhanced intervention was tested in a feasibility study. Adults with visual impairment and severe fatigue (n = 10) followed the intervention partially with guidance from a social worker and one-time computer trainer support. Fatigue severity (Checklist Individual Strength), fatigue impact (Modified Fatigue Impact Scale) and cognitive behavioral therapy skills (Competencies of Cognitive Therapy Scale-Self Report) were measured at baseline and at three months follow-up and analyzed with the Wilcoxon signed-rank test. The intervention was evaluated through evaluation forms. RESULTS: The usability study resulted in adjustments to content and lay-out with regard to optically shortened text sentences, separate pages for information and assignments with one read-aloud audio and an additional descriptive explanation of page content. Digital challenges were overcome with mandatory computer training and e-platform modifications. The feasibility study showed a positive trend in reducing fatigue severity (Z -6.108; P < .001; SD 8.4), impact of fatigue (Z - 4.451; P < .001; SD 11.4) and cognitive behavioral therapy skills (Z -2.278; P = .023; SD 19.3). Participants gave useful feedback regarding accessibility, content and guidance, with an overall positive experience. The intervention was rated with a median score of 8 (range 7-10). CONCLUSION: We developed, evaluated and optimized E-nergEYEze by applying a user-centered and iterative approach. E-nergEYEze showed a promising trend to reduce fatigue severity and impact of fatigue and to increase cognitive behavioral therapy skills. The study methods were feasible and the fidelity of the intervention protocol was suitable. Performing a randomized controlled trial is warranted to give insight into whether E-nergEYEze is cost-effective in reducing severe fatigue in adults with visual impairment. TRIAL REGISTRATION: International Clinical Trial Registry Platform: NL7764. Date registered: 28-05-2019.

BACKGROUND: Person-centered care is needed to effectively support workers with chronic health conditions. Person-centered care aims to provide care tailored to an individual person's preferences, needs and values. To achieve this, a more active, supportive, and coaching role of occupational and insurance physicians is required. In previous research, two training programs and an e-learning training with accompanying tools that can be used in the context of person-centered occupational health care were developed to contribute to this changing role. The aim was to investigate the feasibility of the developed training programs and e-learning training to enhance the active, supportive, and coaching role of occupational and insurance physicians needed for person-centered occupational health care. Information about this is important to facilitate implementation of the tools and training into educational structures and occupational health practice. METHODS: A qualitative study was conducted, with N = 29 semi-structured interviews with occupational physicians, insurance physicians, and representatives from occupational educational institutes. The aim was to elicit feasibility factors concerning the implementation, practicality and integration with regard to embedding the training programs and e-learning training in educational structures and the use of the tools and acquired knowledge and skills in occupational health care practice after following the trainings and e-learning training. Deductive analysis was conducted based on pre-selected focus areas for a feasibility study. RESULTS: From an educational perspective, adapting the face-to-face training programs to online versions, good coordination with educational managers and train-the-trainer approaches were mentioned as facilitating factors for successful implementation. Participants underlined the importance of aligning the occupational physicians' and insurance physicians' competences with the educational content and attention for the costs concerning the facilitation of the trainings and e-learning training. From the professional perspective, factors concerning the content of the training and e-learning training, the use of actual cases from practice, as well as follow-up training sessions were reported. Professionals expressed good fit of the acquired skills into their consultation hour in practice. CONCLUSION: The developed training programs, e-learning training and accompanying tools were perceived feasible in terms of implementation, practicality, and integration by occupational physicians, insurance physicians and educational institutes.

BACKGROUND: To support occupational physicians (OPs) in the implementation of workers' health surveillance (WHS), a training programme was developed. AIMS: (i) To evaluate the effects of a WHS training programme for OPs on knowledge, self-efficacy and skills to implement WHS. (ii) To evaluate to what extent a WHS training programme is acceptable and feasible for implementation in practice. METHODS: A single-blinded randomized controlled trial with waiting-list control group was used. The WHS training programme consisted of an e-learning and a 4.5-h online training session. OPs completed a knowledge test (0-8), self-efficacy questionnaires on knowledge and skills (6-60), and vignette assignments (0-16) to measure skills. OPs completed the questionnaires, either before and after the WHS training programme (intervention group), or before the training programme (control group) while receiving the training programme after the waiting period. All OPs completed questionnaires about the training's acceptability, and feasibility for implementation in practice. ANCOVA and Poisson regression analyses were conducted. RESULTS: The self-efficacy score (M = 44.1 versus M = 37.2) (P < 0.001) and skills score (M = 9.6 versus M = 8.3) (P < 0.05) of OPs in the training group (N = 16) were higher than the control group (N = 23). No effect was found on knowledge. Evaluation of acceptability and feasibility showed that 21 (58%) OPs were very satisfied with the training part on initiating WHS, and 29 (85%) would recommend the WHS training programme to colleagues. CONCLUSIONS: This WHS training programme has a positive effect on self-efficacy and skills of OPs to implement WHS, and may be acceptable and feasible to implement in practice.

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

Purpose Based on current scientific evidence and best practice, the first Dutch multidisciplinary practice guideline for occupational health professionals was developed to stimulate prevention and enhance work participation in patients with low back pain (LBP) and lumbosacral radicular syndrome (LRS). Methods A multidisciplinary working group with health care professionals, a patient representative and researchers developed the recommendations after systematic review of evidence about (1) Risk factors, (2) Prevention, (3) Prognostic factors and (4) Interventions. Certainty of the evidence was rated with GRADE and the Evidence to Decision (EtD) framework was used to formulate recommendations. High or moderate certainty resulted in a recommendation "to advise", low to very low in a recommendation "to consider", unless other factors in the framework decided differently. Results An inventory of risk factors should be considered and an assessment of prognostic factors is advised. For prevention, physical exercises and education are advised, besides application of the evidence-based practical guidelines "lifting" and "whole body vibration". The stepped-care approach to enhance work participation starts with the advice to stay active, facilitated by informing the worker, reducing workload, an action plan and a time-contingent increase of work participation for a defined amount of hours and tasks. If work participation has not improved within 6 weeks, additional treatments should be considered based on the present risk and prognostic factors: (1) physiotherapy or exercise therapy; (2) an intensive workplace-oriented program; or (3) cognitive behavioural therapy. After 12 weeks, multi-disciplinary (occupational) rehabilitation therapy need to be considered. Conclusions Based on systematic reviews and expert consensus, the good practice recommendations in this guideline focus on enhancing work participation among workers with LBP and LRS using a stepped-care approach to complement existing guidelines focusing on recovery and daily functioning.

BACKGROUND: The aim was to identify the most important determinants of practice for the implementation of person-centered tools which enhance work participation for patients with chronic health conditions. METHODS: A mixed-method study was conducted consisting of semi-structured interviews, a focus group and a survey. Various stakeholders were involved including (representatives of) workers with chronic health conditions, insurance physicians, occupational physicians, other healthcare professionals, researchers, employers, and policymakers. The semi-structured interviews were performed to identify implementation determinants, followed by a focus group to validate resulting determinants. To conclude, a survey was conducted to select the most important implementation determinants through prioritization by ranking the order of importance. The Tailored Implementation of Chronic Diseases checklist (TICD) was used as concept-driven coding frame for the qualitative analysis of the interviews and focus group. The self-developed survey was based on the domains of the TICD. The survey was analyzed by frequency count of first ranking of determinants per and between domains of the TICD. RESULTS: Various stakeholders participated (N = 27) in the interviews and focus group. The qualitative data retrieved yielded a list of determinants with additional in-depth themes according to the TICD. For the selection of the most important determinants, a survey with 101 respondents was conducted, consisting of occupational physicians, insurance physicians and workers with a chronic health condition. From the seven domains of the TICD, respondents emphasized the importance of taking into account the needs and factors associated with workers with a chronic health condition as this determinant ranked highest. Taking into account the individual needs and wishes of workers was mentioned to enable successful implementation, whereas stress of the workers was indicated to impede implementation. Other important determinants included 'being able to work with the tools' in terms of time and usability or 'cognitions, beliefs and attitudes of occupational and insurance physicians' to be able to use the tools. CONCLUSION: This study identified the most important determinants from the perspective of various stakeholders involved in the implementation of client-centered tools in occupational health for workers with chronic health conditions. Furthermore, by prioritizing the most important determinants, targeted implementation strategies can be developed.

PURPOSE: Clinicians need to know whether inguinal hernia (IH) can be attributed to work to answer questions regarding prevention and medical causation. This review describes whether work-related risk factors are associated with IH. METHODS: A systematic review was performed in Medline via PubMed until February 3rd, 2020. Inclusion criteria were that IH was diagnosed by a clinician, and workers exposed to work-related risk factors were compared to workers less exposed or not at all. A quality assessment and a meta-analysis using Cochrane's RevMan 5.3 were performed, including GRADE for quality of evidence. RESULTS: The search resulted in 540 references. Fourteen studies fulfilled the inclusion criteria, of which three were included in a meta-analysis, all three being of high quality, including 621 workers diagnosed with IH. The meta-analysis revealed significant associations with physically demanding work (OR 2.30, 95% CI 1.56-3.40). Two prospective studies, including 382 and 22,926 cases revealed associations that this was true for male workers with a lateral IH that reported standing or walking for more than six hours per workday (OR 1.45, 95% CI 1.12-1.88) or lifting cumulative loads of more than 4000 kg per workday (OR 1.32, 95% CI 1.27-1.38). The level of certainty for the latter two work-related risk factors was moderate and high according to GRADE. CONCLUSION: Lateral IH among males is associated with work-related risk factors depending on the level of exposure to the time standing/walking per workday, or the amount of load lifted per workday.

To support occupational physicians in their assessment and notification of occupational diseases, diagnostic registration guidelines are developed with information about associations between work-related risk factors and diseases. The objective of this review of systematic reviews is to examine whether work-related risk factors are associated with chronic pulmonary obstructive disease (COPD). We searched the electronic database of Medline for systematic reviews published between 1 January 2009 and 20 June 2017. Reviews were included when COPD was assessed by data on lung function and when work-related exposures to vapors, dusts, gases, or fumes (VDGF) were described. One author selected studies and extracted data; two authors assessed study quality using A MeaSurement Tool to Assess systematic Reviews (AMSTAR). In all eight systematic reviews included, various exposures to vapors, dusts, gases, and fumes (VGDF) at work are associated with COPD. Two-thirds of the included studies are cross-sectional and show a high heterogeneity in population, setting, and mostly self-reported-exposures. Two high-quality reviews (AMSTAR score ≥ 9) including meta-analyses show associations and excess risk of COPD for work-related general exposure to VDGF with a summary odds ratio of 1.4 (95% confidence interval (CI) 1.19â»1.73) and to inorganic dust with a mean difference in predicted forced expiratory volume in one second (FEV1) of -5.7% (95% CI: -8.62% to -2.71%). Exposure to VGDF at work is associated with a small but increased risk of COPD. More detailed workplace measurements of specific VGDF are warranted to gain an insight into doseâ»response relationships.
RESUMEN
BACKGROUND: Mandatory medical examinations (MMEs) of workers should be based on the health and safety requirements that are needed for effectively performing the relevant work. For police personnel in the Netherlands, no job-specific MME exists that takes the specific tasks and duties into account. AIMS: To provide the Dutch National Police with a knowledge base for job-specific MMEs for police personnel that will lead to equitable decisions from an occupational health perspective about who can perform police duties. METHODS: We used a stepwise mixed-methods approach in which we included interviews with employees and experts and a review of the national and international literature. We determined the job demands for the various police jobs, determined which were regarded as specific job demands and formulated the matching health requirements as specific as possible for each occupation. RESULTS: A total of 21 specific job demands were considered relevant in different police jobs. These included biomechanical, physiological, physical, emotional, psychological/cognitive and sensory job demands. We formulated both police-generic and job-specific health requirements based on the specific job demands. Two examples are presented: bike patrol and criminal investigation. CONCLUSIONS: Our study substantiated the need for job-specific MMEs for police personnel. We found specific job demands that differed substantially for various police jobs. The corresponding health requirements were partly police-generic, and partly job-specific.

Acquired brain injury may lead to cognitive, emotional and behavioural problems which often go unrecognised. Combined with the patient's lack of self-awareness this may impede social participation, in particular in returning to work. To stress the importance of diagnosing and treating such consequences, we present two patients. A 40-year-old man suffering from the invisible consequences of brain injury caused by several cerebral infarctions. He tried but failed several times to hold down a job before he was sent to a specialized vocational rehabilitation centre. A 28-year-old man with severe traumatic brain injury started vocational rehabilitation at an early stage. This resulted in a full return to work within six months of the trauma. The Dutch guideline on acquired brain injury and vocational participation aims to help professionals and patients in the vocational rehabilitation process. The guideline strongly recommends setting up an interdisciplinary team consisting of a rehabilitation physician, an occupational physician, and employer and employee.

PURPOSE: We aim to provide evidence for improving fit to work assessments for rail safety workers and raised the question whether adding an assessment of work limitations is useful. Therefore, we assessed differences in the proportions of perceived work limitations and reported health complaints and whether older age or having health complaints are risk factors for having work limitations. METHODS: Job requirements for rail safety workers are 'vigilance and clear judgment', 'good communication abilities', 'sufficient eye sight' and 'task-required physical abilities'. We invited 1000 workers to fill in a questionnaire about perceived work limitations and health problems related to their job requirements. Proportions of the two were compared by using the McNemar test. Associations were analyzed by using univariate logistic regression. RESULTS: Among 484 rail safety workers, we found statistically significant differences between the proportions of reported health complaints (2-26 %) and work limitations (10-32 %). No significant associations were found between older age and work limitations, except for workers in the age group 40-50 years regarding physical abilities. This was not found for the age group over 50 years. For each age category, workers reporting health complaints related to 'vigilance and clear judgment' and 'sufficient physical abilities' had a statistically significant increased risk for reporting work limitations as well (ORs 2.4-17.9). CONCLUSIONS: Our results indicate that fit to work assessments should include both health complaints and work limitations. Our results do not substantiate the assumption that workers over 40 years of age are at increased risk for work limitations in general.

PURPOSE: Specific physical activities or working conditions are suspected for increasing the risk of preterm birth (PTB). The aim of this meta-analysis is to review and summarize the pre-existing evidence on the effect of shift work or long working hours on the risk of PTB. METHODS: We conducted a systematic search in MEDLINE and EMBASE (1990-2013) for observational and intervention studies with original data. We only included articles that met our specific criteria for language, exposure, outcome, data collection and original data that were of at least of moderate quality. The data of the included studies were pooled. RESULTS: Eight high-quality studies and eight moderate-quality studies were included in the meta-analysis. In these studies, no clear or statistically significant relationship between shift work and PTB was found. The summary estimate OR for performing shift work during pregnancy and the risk of PTB were 1.04 (95% CI 0.90-1.20). For long working hours during pregnancy, the summary estimate OR was 1.25 (95% CI 1.01-1.54), indicating a marginally statistically significant relationship but an only slightly elevated risk. CONCLUSION: Although in many of the included studies a positive association between long working hours and PTB was seen this did reach only marginal statistical significance. In the studies included in this review, working in shifts or in night shifts during pregnancy was not significantly associated with an increased risk for PTB. For both risk factors, due to the lack of high-quality studies focusing on the risks per trimester, in particular the third trimester, a firm conclusion about an association cannot be stated.

OBJECTIVE: Physically demanding work may increase the risk of preterm delivery (PTD), defined as delivery before 37 weeks. We assessed the available evidence. METHODS: A systematic search in Medline, Embase and Nioshtic for the period 1990 to June 2012 for observational and intervention studies on physically demanding work (prolonged standing, heavy lifting, physical exertion, occupational fatigue and demanding posture) and PTD. Selected studies were assessed for their risk of bias and pooled using a random effects model. Results of case-control and cohort studies were reported separately in subgroups. RESULTS: We found 10 studies with low risk of bias and seven studies with moderate risk of bias. Standing and walking at work during pregnancy for more than 3 h per day was associated with an increased risk for PTD [OR 1.3 (95% CI 1.1-1.6)], just as lifting and carrying >5 kg [OR 1.3 (95% CI 1.05-1.6)] or lifting and carrying in the third trimester of the pregnancy [OR 1.3 (95% CI 1.01-1.8)]. Jobs that required physical effort or physical exertion were associated with an increased risk of PTD [OR 1.4 (95% CI 1.19-1.66)]. Working during pregnancy in jobs with a combination of two or more physical tasks, physical effort or occupational fatigue was also associated with an increased risk of PTD [OR 1.5 (95% CI 1.1-2.0)]. CONCLUSIONS: Physically demanding work during pregnancy is associated with an increased risk of PTD, especially in jobs with a combination of tasks with physical effort. In general, only small to moderate elevations of risks were found.

OBJECTIVE: Analysis of a dose-response pattern between exposure to whole body vibration (WBV) and low back pain (LBP) in a group of drivers. METHODS: This study assessed individual factors, work-related risk factors, various LBP outcome measures and LBP disability in a group of drivers (n = 571) approached at baseline (T0), as well as the WBV magnitude of a representative sample of their vehicles (n = 49), at T0 and at 1-year follow-up (T1). Data were collected using a self-administered questionnaire and actual field measurements according to ISO 2631-1. The magnitude and duration of vibration exposure and a variety of daily and cumulative WBV-exposure measures were calculated for each driver. RESULTS: 229 drivers (40.1%) completed both questionnaires (T0 and T1). The magnitude of WBV was comparable over time. Depending on the LBP outcome, various individual factors (marital status, back trauma and smoking) and work-related risk factors (previous job with heavy physical loading, lifting, bending and the physical risk index) related significantly to onset (all, p<0.05). After adjusting for these contributing factors, the study found a significant trend (an increase in odds ratios of developing LBP with an increase in WBV exposure) for driving-related LBP with daily driving time (p<0.03), and the cumulative measures total hours of exposure (p<0.01), root sum of squares at total dose (p<0.05) and root sum of quads at total dose (p<0.01). No significant trend was found for 12-month LBP. No analysis on a possible dose-response pattern could be derived for either LBP intensity or LBP disability, due to low prevalence. CONCLUSION: The investigation found a dose-response pattern between WBV exposure and driving-related LBP. No indication of a dose-response pattern was found between WBV exposure and 12-month LBP. Although this dose-response pattern is only an indication, these findings imply that WBV exposure might contribute to the onset of driving-related LBP.

OBJECTIVES: To evaluate process and outcome of a multifaceted occupational health intervention programme on whole-body vibration (WBV) in forklift truck drivers. METHODS: An experimental pretest/post-test control group study design. The authors trained occupational health services (OHS) in the experimental group in the use of the programme. OHS in the control group were asked to deliver care as usual. In total, 15 OHS, 32 OHS professionals, 26 companies, and 260 forklift drivers were involved. Post-test measurements were carried out one year after the start of the programme. RESULTS: Baseline data before the start of the programme showed no difference between experimental and control group. Results of the outcome evaluation indicate a slight, although not statistically significant, reduction of WBV exposure in the experimental group (p = 0.06). Process evaluation revealed a positive influence on company policy toward WBV, attitude and intended behaviour of forklift drivers, and a trend towards an increase in knowledge of OHS professionals and company managers. The number of observed control measures with a major impact (levelling of surface and reduction of speed) was rather low. In those cases where control measures had been taken, there was a significant reduction in WBV exposure. This limited effect of the programme might be caused by the short period of follow up and the dropout of participants. The feasibility and the usefulness of the programme within the OHS setting were rated good by the participants. CONCLUSIONS: This programme to decrease WBV exposure was partially effective. Significant effects on intermediate objectives were observed. More research on the effectiveness of intervention in the field of WBV is needed.

OBJECTIVE: The objective of this study was to determine the effectiveness of a training to increase collaboration between general practitioners and occupational health physicians in the treatment of patients with low back pain (LBP) because more collaboration might improve a patient's recovery and shorten sick leave. METHODS: In a controlled trial, the intervention in one region was compared with usual care in a control region. Participating physicians enrolled patients with LBP on sick leave for 3-12 weeks. Patients filled out three questionnaires: at inclusion, at 3 months, and at 6 months. Information on sick leave was gathered from occupational health services. All analyses were performed on an intention-to-treat basis. RESULTS: Fifty-six patients with LBP were enrolled in each region. There was little collaboration between physicians during the project. Patients in the intervention region returned to work significantly later (P=.005) but were significantly more satisfied with their occupational health physician (P=.01). No differences were found between the intervention and control patients for pain, disability, quality of life, and medical consumption. CONCLUSION: Our study does not show a positive effect of the training to increase collaboration between general practitioners and occupational health physicians. The training may not have improved collaboration enough to influence the prognosis of LBP.
