Emergency medicine is a branch of medicine that is practiced in a hospital emergency department, in the field by emergency medical service, such as paramedics, and other locations where initial medical treatment of illness takes place. Just as clinicians operate by immediacy rules under large emergency systems, emergency physicians and other allied health care workers in the emergency department base their practice on a triage system. Emergency medicine focuses on diagnosis and treatment of acute illnesses and injuries that require immediate medical attention. While not usually providing long-term or continuous care, emergency medicine physicians and paramedics still provide care with the aim of improving long-term patient outcome. This new book presents the latest research from around the globe in this field.
