The mission of California Emergency Medical Services Authority is to prevent injuries, reduce suffering, and save lives by developing standards for and administering an effective statewide coordinated system of quality emergency medical care and disaster medical response that integrates public health, public safety, and healthcare. The EMS Authority is charged with providing leadership in developing and implementing EMS systems throughout California and setting standards for the training and scope of practice of various levels of EMS personnel. The EMS Authority also has responsibility for promoting disaster medical preparedness throughout the state, and, when required, coordinating and supporting the state's medical response to major disasters. Emergency and disaster medical services in California are rooted in the skills and commitment of the first responders, EMTs, nurses, physicians, and administrators who deliver care to the public and operate the system. In order for high quality services to be delivered with high efficiency, all aspects of EMS systems must work together, mutually reinforcing and supporting each other for the benefit of the patient. The California EMS Authority, through standard setting, consensus building, and leadership, plays a central role in improving the quality of emergency medical services available for all Californians.
