Burnout is an occupational hazard precipitated by chronic exposure to excessive work-related stress. It can have negative impacts on the health and safety of patients and clinicians. Anaesthesiologists are at a high risk of burnout; anaesthetic residents especially may experience higher levels of stress as a result of training requirements and postgraduate examinations. However, the scale of burnout among anaesthesiology residents is not well evaluated. To determine the prevalence of burnout and identify risk factors contributing to it among anaesthesiology residents worldwide and evaluate preventive strategies at institutional and departmental levels. A systematic review without meta-analysis. We searched PubMed, Embase, Scopus and PsycInfo for English language articles published up to 24 May 2021. The inclusion criteria for qualitative analysis were a reported burnout prevalence in anaesthesiology residents and the use of an assessment tool. Exclusion criteria were reviews/meta-analyses/correspondence, non-English articles, articles without anaesthesiology residents and lacking information on burnout prevalence and metrics for assessment. Twelve studies met the inclusion criteria; seven studies utilised the 22-item Maslach Burnout Inventory Human Services Survey (MBI-HSS) and five utilised the abbreviated Maslach Burnout Inventory (aMBI). The reported burnout prevalence among anaesthesiology residents varied between 2.7 and 67.0% (median = 24.7%). Differences in burnout criteria contributed significantly to methodological heterogeneity. Factors predisposing to burnout included long working hours, poor workplace relationships, professional examinations and adverse clinical events. Protected rest time and restricted work hours were identified as effective strategies to prevent burnout. Other preventive strategies include mindfulness and resilience courses, as well as departmental initiatives such as exercise. Burnout is common amongst anaesthesiology residents. Standardised tools and diagnostic criteria are needed to distinguish methodological heterogeneity from true heterogeneity in study populations. Interventions have been proposed to improve management strategies to minimise burnout anaesthesiology residents. CRD42019140472.
