ABSTRACT
The COVID-19 pandemic has increased physician burnout beyond high baseline levels. We aimed to determine whether pandemic-related factors contribute to physician burnout beyond known organizational factors. This was a cross-sectional survey of Canadian physicians using a convenience sample. Eligible participants included any physician currently holding a license to practice in Canada. Responses were gathered from May 13 to 12 June 2020. Risk factors measured included the newly developed Pandemic Experiences and Perceptions Scale (PEPS) subscales, contact with virus, pandemic preparation, and provincial caseload. The primary outcome was the Maslach Burnout Inventory (MBI). The primary outcome was completed by 309 respondents. Latent profile analysis found 107 (34.6%) respondents were burned out. In multivariate analysis, exhaustion was independently associated with PEPS adequacy, risk perception, and worklife subscales (adjusted R2 = 0.236, P < 0.001). Cynicism was associated with exhaustion, and PEPS worklife (adjusted R2 = 0.543, P < 0.001). Efficacy was associated with cynicism, PEPS worklife, and active cases (adjusted R2 = 0.152, P < 0.001). Structural equation modelling showed statistically significant direct paths between PEPS areas of worklife and all MBI subscales. Contact with virus, preparation, and PEPS risk perception added to the prediction of MBI exhaustion. Among a sample of Canadian physicians during the COVID-19 pandemic, adequacy of resources, risk perception, and quality of worklife were associated with burnout indices. To mitigate physician burnout organizations should work to improve working conditions, ensure adequate resources, and foster perceived control of risk of transmission.Trial Registration: NCT04379063.
