Introduction
The COVID-19 pandemic necessitated a shift to virtual curriculum delivery at Canadian medical schools. At the NOSM University, some learners transitioned to entirely online learning, while others continued in-person, in-clinic learning. This study aimed to show that medical learners who transitioned to exclusively online learning exhibited higher levels of burnout compared to their peers who continued in-person, clinical learning. Analysis of factors that protect against burnout including resilience, mindfulness, and self-compassion exhibited by online and in-person learners at NOSM University during this curriculum shift were also explored.
Methods
As part of a pilot wellness initiative, a cross-sectional online survey-based study of learner wellness was conducted at NOSM University during the 2020–2021 academic year. Seventy-four learners responded. The survey utilized the Maslach Burnout Inventory, the Brief Resilience Scale, Cognitive and Affective Mindfulness Scale–Revised, and the Self-Compassion Scale–Short Form. T-tests were utilized to compare these parameters in those who studied exclusively online and those who continued learning in-person in a clinical setting.
Results
Medical learners who engaged in online learning exhibited significantly higher levels of burnout when compared with learners who continued in-person learning in a clinical setting, despite scoring equally on protective factors such as resilience, mindfulness, and self-compassion.
Conclusion
The results discussed in this paper suggest that the increased time spent in a virtual learning environment during the COVID-19 pandemic might be associated with burnout among exclusively online learners, as compared to learners who were educated in clinical, in-person settings. Further inquiry should investigate causality and any protective factors that could mitigate negative effects of the virtual learning environment.
