Impact of a manager-oriented intervention on occupational exposures and well-being among pregnant hospital and day-care employees: A cluster randomised trial.

BACKGROUND: Pregnancy can make it difficult to cope with demands at work and may affect women's well-being. We investigated if a manager-targeted educational intervention reduced demanding occupational exposures and improved the psychosocial work environment and well-being among pregnant employees. METHODS: Data came from a cluster randomised trial in Danish hospitals and day-care institutions. Work units were assigned randomly and were non-blinded to the intervention, where managers were either invited to participate in a three-hour seminar addressing job adjustment in pregnancy or assigned to a control group undertaking their usual practice. Self-reported outcomes by pregnant employees at the work units were the proportion of pregnant employees with demanding occupational exposures, good psychosocial work environment and good well-being. Mixed logistic regression was applied in the population of responders and in intention-to-treat analyses using multiple imputations. RESULTS: We included 915 pregnant employees: 451 in the intervention group and 464 in the control group. Of 216 invited managers, 103 (48%) participated in the seminar. A total of 339 (37%) pregnant employees answered the questionnaire. The proportion of pregnant employees who had demanding occupational exposures, good psychosocial work environment and good well-being in the intervention versus the control group were 36% versus 39% (odds ratio (OR)=0.90, 95% confidence interval (CI) 0.57-1.44), 56% versus 59% (OR=1.01, 95% CI 0.60-1.71) and 77% versus 73% (OR=1.13, 95% CI 0.68-1.87), respectively. CONCLUSIONS: This manager-targeted educational intervention did not reduce demanding occupational exposures and did not improve the psychosocial work environment or the well-being among pregnant employees in hospital and day-care settings. Comprehensive and participatory interventions may be considered in future studies.

Manager-oriented intervention to reduce absence among pregnant employees in the healthcare and daycare sector: a cluster randomised trial.

OBJECTIVE: The aim was to test if targeting managers with an educational intervention reduces absence among pregnant employees. METHODS: The study was a non-blinded cluster randomised trial conducted in hospitals and daycare institutions from two administrative Danish Regions and two Danish municipalities. Clusters (work units) were assigned randomly and non-blinded to either (1) intervention, where all managers were invited to participate in a 3-hour seminar addressing needs and options for adjustment of work in pregnancy, or (2) control, with practice as usual. The primary outcome based on payroll data was long-term pregnancy-related absence, defined as ≥12.5% cumulated absence during pregnancy weeks 1-32. Intention-to-treat analysis was applied using mixed logistic regression. RESULTS: Ninety work units were included (56 hospital departments and 34 daycare units) with 451 pregnant employees in the intervention group and 464 in the control group. Work units had on average 11 pregnant employees with no difference between the groups. 103 of the 216 invited managers (48%) participated in a the 3-hour seminar. In the intervention group, 154 (34%) had long-term pregnancy-related absence during pregnancy weeks 1-32 vs 166 (36%) in the control group. Relative odds of having long-term pregnancy-related absence, when being in the intervention group, was 1.06 (95% CI 0.71 to 1.58), with an interclass correlation coefficient of 0.07. CONCLUSION: An educational intervention targeting managers did not reduce pregnancy-related absence among pregnant employees. TRIAL REGISTRATION NUMBER: NCT03002987.

Systematic literature review on the effects of occupational safety and health (OSH) interventions at the workplace.

Objectives The aim of this review was to assess the evidence that occupational safety and health (OSH) legislative and regulatory policy could improve the working environment in terms of reduced levels of industrial injuries and fatalities, musculoskeletal disorders, worker complaints, sick leave and adverse occupational exposures. Methods A systematic literature review covering the years 1966‒2017 (February) was undertaken to capture both published and gray literature studies of OSH work environment interventions with quantitative measures of intervention effects. Studies that met specified in- and exclusion criteria went through an assessment of methodological quality. Included studies were grouped into five thematic domains: (i) introduction of OHS legislation, (ii) inspection/enforcement activity, (iii) training, such as improving knowledge, (iv), campaigns, and (v) introduction of technical device, such as mechanical lifting aids. The evidence synthesis was based on meta-analysis and a modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Results The search for peer-reviewed literature identified 14 743 journal articles of which 45 fulfilled the inclusion criteria and were eligible for meta-analysis. We identified 5181 articles and reports in the gray literature, of which 16 were evaluated qualitatively. There was moderately strong evidence for improvement by OHS legislation and inspections with respect to injuries and compliance. Conclusions This review indicates that legislative and regulatory policy may reduce injuries and fatalities and improve compliance with OHS regulation. A major research gap was identified with respect to the effects of OSH regulation targeting psychological and musculoskeletal disorders.
