By any standard one wishes to apply, the impact of violence on the health and safety of the public is significant. The expression of violence among children in the United States has increased significantly during the modern era. Homicide and suicide are the second and third leading causes of death in youths 15-24 years of age. The emergency department (ED) is a common site for the care of these victims, and because victims often become assailants, the emergency care provider needs to know the epidemiology, treatment, and methods for prevention of youth violence in order to curtail the cycle. A multidisciplinary task force was convened by the Centers for Disease Control and Prevention (CDC)-funded Southern California Center of Academic Excellence on Youth Violence Prevention and the Keck School of Medicine at the University of Southern California to define competencies for health professionals in youth violence prevention and control. Three levels of competence were identified: the generalist level, which should be obtained by all health professionals; the specialist level, which should be obtained by health professionals such as emergency medicine providers, who frequently work with populations affected by violence; and a third, or scholar level, to be acquired by health professionals who wish to become experts not only in the care, but also in research and advocacy. This article reports the details of this group's efforts and applies them to emergency care provider education. These competencies should shape the development of curricula for the span of emergency medical training from emergency medical services scholastic training to postgraduate continuous medical education.
