As US health care systems undergo a period of transformative change, so too will emergency care, and more specifically emergency departments. This transformation will include: * The development of new diagnostic, therapeutic, and information technologies * A growing need to prepare and respond to emerging public health threats * The expansion of the role of allied health professionals to address the workforce crisis * Novel expectations for care coordination * The fundamental economics of emergency care under new payment models, and * The key relationship with American law. Emergency Care and the Public's Health explores the complex role of emergency care in the context of these changes and as an increasingly vital component of health care systems both within and outside the US. From an expert emergency medicine team, this new title is a reference for emergency care and critical care providers, allied health professionals and hospital administrators. It is also for relevant for public policy and healthcare policy professionals.
