Planning for the next pandemic: Reflections on lessons from the uncontained transmission phases of the COVID-19 pandemic and their impacts on emergency departments in Australia.

Australia was a world leader in managing the earlier waves of the COVID-19 pandemic. Subsequently, three major turning points changed the trajectory of the pandemic: mass vaccinations, emergence of more transmissible variants and re-opening of Australia's borders. However, there were also concomitant missteps and premature shifts in pandemic response policy that led to mixed messaging, slow initial vaccination uptake and minimal mitigation measures in response to the Omicron variant. The latter marked Australia's entry into a new phase of (or approach to) the pandemic: widespread transmission. This led to an exponential increase in cases and significant impacts on the health system, particularly, EDs. This paper reflects on this phase of the pandemic to urge for system-level changes that instal better safeguards for ED capacity, safety and staff well-being for future pandemics. This is essential to strengthening our health system's resilience and to better protecting our communities against such emergencies.
