ABSTRACT
A pandemic has sent the world into chaos. It has not only upended our lives; hundreds of thousands of lives have already been tragically lost. The global crisis has been disruptive, even a threat, to healthcare simulation, affecting all aspects of operations from education to employment. While simulationists around the world have responded to this crisis, it has also provided a stimulus for the continued evolution of simulation. We have crafted a manifesto for action, incorporating a more comprehensive understanding of healthcare simulation, beyond tool, technique or experience, to understanding it now as a professional practice. Healthcare simulation as a practice forms the foundation for the three tenets comprising the manifesto: safety, advocacy and leadership. Using these three tenets, we can powerfully shape the resilience of healthcare simulation practice for now and for the future. Our call to action for all simulationists is to adopt a commitment to comprehensive safety, to advocate collaboratively and to lead ethically.
