The process for developing national emergency management strategies for both the United States and the United Kingdom has led to the formulation of differing approaches to meet similar desired outcomes. Historically, the pathways for each are the result of the enactment of legislation in response to a significant event or a series of events. The resulting laws attempt to revise practices and policies leading to more effective and efficient management in preparing, responding, and mitigating all types of natural, manmade, and technological hazards. Following the turn of the 21st century, each country has experienced significant advancements in emergency management including the formation and utilization of 2 distinct models: health care coalitions in the United States and resiliency forums in the United Kingdom. Both models have evolved from circumstances and governance unique to each country. Further in-depth study of both approaches will identify strengths, weaknesses, and existing gaps to meet continued and future challenges of our respective disaster health care systems.
