Background. Throughout history, communities have faced outbreaks of infectious diseases and other natural and man-made disasters that pose significant threats to lives, public health, and business continuity. Many of these disasters are crises that require critical decisions to be made in a short, crucial time with limited information and unforeseen circumstances amidst panic, fear, and shock. The COVID-19 pandemic is a recent example, with public leaders responding to and formulating strategies to attenuate the relentless waves of transmission and surges in resource demands. The pandemic underscored the importance of understanding how healthcare leaders make decisions in-crisis and what factors healthcare leaders prioritize in their decision-making process. Methods/Design. PubMed(NLM), Embase(Ovid), Scopus(Elsevier), Business Source(EBSCOhost), and ProQuest will be searched for primary qualitative studies published in English to explore the multi-faceted decision-making processes of healthcare leaders during a public health crisis. A meta-ethnographic approach will synthesize insights into healthcare leaders’ experiences and perspectives and generate a conceptual theory of decision-making in crisis. Discussion. Understanding how healthcare leaders make critical decisions during public health crises takes advantage of the lessons learned to inform how future health crises are managed.
