Background: Health care workers (HCWs) are among the most vulnerable groups to experience burnout during the coronavirus (COVID-19) pandemic. Understanding the risk and protective factors of burnout is crucial in guiding the development of interventions; however, the understanding of burnout determinants in the Canadian HCW population remains limited.Objective: Identify risk and protective factors associated with burnout in Canadian HCWs during the COVID-19 pandemic and evaluate organizational factors as moderators in the relationship between COVID-19 contact and burnout.Methods: Data were drawn from an online longitudinal survey of Canadian HCWs collected between 26 June 2020 and 31 December 2020. Participants completed questions pertaining to their well-being, burnout, workplace support and concerns relating to the COVID-19 pandemic. Baseline data from 1029 HCWs were included in the analysis. Independent samples t-tests and multiple linear regression were used to evaluate factors associated with burnout scores.Results: HCWs in contact with COVID-19 patients showed significantly higher likelihood of probable burnout than HCWs not directly providing care to COVID-19 patients. Fewer years of work experience was associated with a higher likelihood of probable burnout, whereas stronger workplace support, organizational leadership, supervisory leadership, and a favourable ethical climate were associated with a decreased likelihood of probable burnout. Workplace support, organizational leadership, supervisory leadership, and ethical climate did not moderate the associations between contact with COVID-19 patients and burnout.Conclusions: Our findings suggest that HCWs who worked directly with COVID-19 patients, had fewer years of work experience, and perceived poor workplace support, organizational leadership, supervisory leadership and ethical climate were at higher risk of burnout. Ensuring reasonable work hours, adequate support from management, and fostering an ethical work environment are potential organizational-level strategies to maintain HCWs' well-being. Canadian HCWs endorsed high levels of burnout during the COVID-19 pandemic.Having direct contact with COVID-19 patients and having fewer years of work experience were associated with a higher likelihood of probable burnout.Having stronger workplace support, greater perceived organizational and supervisory leadership, and a favourable ethical climate were associated with a lower likelihood of probable burnout. Antecedentes: Los trabajadores de la salud (HCWs en su sigla en ingl & eacute;s) est & aacute;n entre los grupos m & aacute;s vulnerables a experimentar burnout durante la pandemia del coronavirus (COVID-19). Es crucial entender los factores de riesgo y protectores del burnout para guiar el desarrollo de intervenciones; sin embargo, el entendimiento de los determinantes del burnout en la poblaci & oacute;n de HCW canadienses permanece limitado.Objetivo: Identificar los factores de riesgo y protectores asociados con el burnout en los HCWs canadienses durante la pandemia del COVID-19 y evaluar los factores organizacionales como moderadores en la relaci & oacute;n entre el contacto del COVID-19 y el burnout.M & eacute;todos: Los datos fueron obtenidos de una encuesta longitudinal en l & iacute;nea de los HCWs canadienses recolectadas entre el 26 de junio de 2020 y el 31 de diciembre de 2020. Los participantes completaron preguntas relacionadas con su bienestar, burnout, apoyo en el lugar de trabajo y preocupaciones con respecto a la pandemia del COVID-19. Se incluyeron en el an & aacute;lisis los datos de tamizaje de 1029 HCWs. Se usaron prueba t para muestras independientes y regresi & oacute;n lineal m & uacute;ltiple para evaluar los factores asociados con los puntajes de burnout.Resultados: Los HCWs en contacto con pacientes del COVID-19 mostraron significativamente probabilidades m & aacute;s altas de posible burnout que los HCWs que no proporcionaron cuidado directo a pacientes del COVID-19. Menos a & ntilde;os de experiencia laboral se asoci & oacute; con una probabilidad significativamente m & aacute;s alta de probable burnout, mientras que un apoyo m & aacute;s fuerte en el lugar de trabajo, liderazgo organizacional, liderazgo del supervisor, y un clima & eacute;tico favorable se asociaron con una disminuci & oacute;n de la probabilidad de posible burnout. El apoyo en el lugar de trabajo, liderazgo organizacional, liderazgo del supervisor, y clima & eacute;tico no moderaron las asociaciones entre el contacto con pacientes del COVID-19 y burnout.Conclusi & oacute;n: Nuestros hallazgos sugieren que los HCWs que trabajaron directamente con los pacientes del COVID-19, ten & iacute;an menos a & ntilde;os de experiencia laboral, y percib & iacute;an un apoyo en el lugar de trabajo, un liderazgo organizacional, un liderazgo de supervisi & oacute;n, y clima & eacute;tico deficientes, ten & iacute;an un mayor riesgo de burnout. Garantizar horarios de trabajo razonables, apoyo adecuado de la administraci & oacute;n, y promover un ambiente de trabajo & eacute;tico son potenciales estrategias a nivel organizacional para mantener el bienestar de los HCWs.
