Many drugs are effective systemically, but slow onset of non-intravenous routes of administration may limit their clinical utility. While anesthesiologists usually have intravenous (IV) access for drug delivery, other healthcare professionals in less controlled situations such as acute crises in the emergency room, critical care settings, or urgent needs in the community, may need non-invasive drug delivery [1].

The COVID-19 pandemic of 2020-2023 significantly affected emergency medical care. Physicians who regularly saw their patients by appointment were redeployed to emergency care, increasing their reported burnout. Understanding how the burnout of specialists increased from this redeployment during COVID-19 is relevant to finding ways to reduce redeployment burnout in these appointment-based physicians when preparing for future pandemics.
