Sustaining the Australian respiratory workforce through the COVID-19 pandemic: a scoping literature review

The outbreak of the COVID-19 pandemic in late 2019 and in 2020 presented challenges to healthcare workers (HCW) around the world that were unexpected and dramatic. The relentless progress of infection, starting in China and rapidly spreading to Europe, North America and elsewhere gave more remote countries, like Australia, time to prepare but also time for unease. HCW everywhere had to readjust and change their work practices to cope. Further waves of infection and transmission with newer variants pose challenges to HCW and health systems, even after mass vaccination. Respiratory medicine HCW found themselves at the frontline, developing critical care services to support intensive care units and grappling with unanticipated concerns about safety, risk and the need to retrain. Several studies have addressed the need for rapid changes in the healthcare workforce for COVID-19 and the impact of this preparation on HCW themselves. In this paper, we present a scoping review of the literature on preparing HCW for the pandemic, explore the Australian experience of building the respiratory workforce and propose evidence-based recommendations to sustain this workforce in an unprecedented high-risk environment.
