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

Abstract
---------------------------

Background: 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 to 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 consensus on the proposed definition using the Delphi technique.
Results: We identified 88 unique definitions of burnout and assigned each of them to one of the 11 original definitions. The semantic analysis yielded a semantic proposal, formulated in accordance with SNOMED-CT 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 the 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.

Three csv files. The first one (ResearchStrings.csv) presents the literature research strings applied to MEDLINE, EMBASE, and PsychINFO, respectively.
The second file (DefinitionsIndexation&Citation_OriginaVsUniqueDef.csv) presents the statements of different definitions of occupational burnout identified within the systematic review, their references and the references of studies citing them.
Finally the third file (DefinitionsIndexation&Citation_UniqueDefinitionSummary.csv) presents the correspondence between these “unique” definitions and their “original” definitions.

{'Abstract': {'Background': '当前，关于职业倦怠的共识性定义尚属阙如。本研究旨在统一医疗研究中职业倦怠作为健康结果的定义，并在欧洲职业队列协调与和谐网络（OMEGA-NET）内达成对此定义的共识。', 'Methods': '首先，我们在 MEDLINE、PsycINFO 和 EMBASE 数据库（1990年1月至2018年8月）中进行了系统综述，并对现有定义进行了语义分析。我们利用系统化医学命名法临床术语（SNOMED-CT）中关于倦怠及其相关概念的界定，提出了一个一致的和谐定义。其次，我们采用德尔菲法寻求对所提定义的共识。', 'Results': '我们识别出88个独特的倦怠定义，并将它们分配到11个原始定义中。语义分析产生了以下符合SNOMED-CT的语义提案：‘在工作者中，职业倦怠或职业心理与情绪衰竭状态是指由于长期暴露于与工作相关的问题而导致的衰竭状态’。在德尔菲的第二轮中，由50位专家（对职业倦怠有兴趣的研究人员和医疗保健专业人员）就这一提案达成共识，其中82%的专家表示同意。', 'Conclusion': '本研究最终在OMEGA-NET内29个国家的专家中达成了一项关于职业倦怠的和谐定义，并获得批准。未来的研究应解决在更大规模专家群体中德尔菲共识的可重复性问题，该群体代表更多国家，并检验该定义的实用性。'}, 'Geographic coverage': {'International': '国际范围'}, 'Analysis unit': {'Number of citations per original and secondary definition of occupational burnout among studies included in the systematic review': '系统综述中包含的研究关于职业倦怠原始定义和次级定义的引用数量'}, 'Kind of data': {'Three csv files.
