Harmonized definition of occupational burnout : A systematic review, semantic analysis, and Delphi consensus in 29 countries

Funding Information: This study was supported by the University of Lausanne and European Cooperation in Science and Technology, Action CA 16216 "Network on the Coordination and Harmonisation of European Occupational Cohorts” (OMEGA-NET). Publisher Copyright: © 2021, Nordic Association of Occupational Safety and Health. All rights reserved.Objective A consensual definition of occupational burnout is currently lacking. We aimed to harmonize the definition of occupational burnout as a health outcome in medical research and reach a consensus on this definition within the Network on the Coordination and Harmonisation of European Occupational Cohorts (OMEGA-NET). Methods First, we performed a systematic review in MEDLINE, PsycINFO and Embase (January 1990 to August 2018) and a semantic analysis of the available definitions. We used the definitions of burnout and burnout-related concepts from the Systematized Nomenclature of Medicine Clinical Terms (SNOMED-CT) to formulate a consistent harmonized definition of the concept. Second, we sought to obtain the Delphi consensus on the proposed definition. Results We identified 88 unique definitions of burnout and assigned each of them to 1 of the 11 original definitions. The semantic analysis yielded a first proposal, further reformulated according to SNOMED-CT and the panelists` comments as follows: "In a worker, occupational burnout or occupational physical AND emotional exhaustion state is an exhaustion due to prolonged exposure to work-related problems". A panel of 50 experts (researchers and healthcare professionals with an interest for occupational burnout) reached consensus on this proposal at the second round of the Delphi, with 82% of experts agreeing on it. Conclusion This study resulted in a harmonized definition of occupational burnout approved by experts from 29 countries within OMEGA-NET. Future research should address the reproducibility of the Delphi consensus in a larger panel of experts, representing more countries, and examine the practicability of the definition.Peer reviewe

BFS Human Behaviour Model for Traffic Safety

The Butterfly Flower Shower (BFS) Human Behaviour Model describes human behaviour in each demanding, possible accidental situation. The BFS human behaviour model is presented for a traffic situation. The key elements (perception, cognition, reaction) of the human behaviour are identified. Also possible limitations and errors in all elements of human behaviour are presented. The model is presented as the butterfly on the flower under the shower of interventions. The flower is environment describing traffic infrastructure composed of the environment, technology and organization. The body of the butterfly is human cognition with personality and motivation. The left wing of the butterfly is the driver’s perception. The right wing of the butterfly is the driver’s reaction. The butterfly presents the driver, the flower presents the road – the traffic infrastructure and the shower presents the shower of humanization interventions into the traffic infrastructure and into the driver. The drops from the shower are related to identified limitations in the traffic infrastructure and to the driver. They are focused on the improvements of perception, cognition and reaction abilities of the driver also with investments into the traffic infrastructure

The structure of psychological examination and assessment of ability for work

Results of psychological test of 46 workers were analysed. All were men with technical high-school education and all worked as operators. Psychological tests and questionnaires for assessment of basic and specific abilities, personality characteristics, level of manifested unavailability and self-estimated fitness for duty were administered. The analysis of results proofs the selection of psycho-diagnostic procedures to be rational and economic. According to the results of factor analysis, all basic mental functions were assessed, which had previously been identified as relevant for job performance by job analysis. According to the results of factor analysis, the administered tests are adequate and their factor structure is clear

Investigating the effects of mobile bottom fishing on benthic carbon processing and storage: a systematic review protocol

Background: Marine sediments represent one of the planet’s largest carbon stores. Bottom trawl fisheries constitute the most widespread physical disturbance to seabed habitats, which exert a large influence over the oceanic carbon dioxide (CO2) sink. Recent research has sparked concern that seabed disturbance from trawling can therefore turn marine sediments into a large source of CO2, but the calculations involved carry a high degree of uncertainty. This is primarily due to a lack of quantitative understanding of how trawling mixes and resuspends sediments, how it alters bioturbation, bioirrigation, and oxygenation rates, and how these processes translate into carbon fluxes into or out of sediments
