New research suggests that  burnout contributed significantly to job dissatisfaction among nurses even before the added stress of the COVID-19 pandemic. Based on national data collected in 2018, 31.5% of nurses who left their jobs in 2017 reported burnout as a reason for leaving. Of nurses who had considered leaving their jobs, even more — 43.4% — reported burnout as a key decision factor. The COVID-19 pandemic has only exacerbated levels of stress and exhaustion among health care workers, and measures must be taken to ensure the well-being and sustainability of the nursing workforce.
