Bureau of Emergency Medical Services & Trauma System

Quality Assurance Reports

The Data & Quality Assurance section of the Bureau is responsible for collecting, analyzing and reporting on data obtained from designated trauma centers and those participating EMS agencies in an effort to enhance the EMS & Trauma System in Arizona.

Regional County & Tribal Reports


Regional EMS plays an esssential role in the care of the patient. These resources are presented to help regions understand how they compare against each other. The EMS regions divide the state into four distinct areas, the Arizona Emergency Medical Services, the Northern Arizona Emergency Medical Services, the Southeastern Arizona EMS Council, and the Western Arizona Council of EMS.

County Level

The EMS and Trauma systems needs vary across towns, counties, and regions in Arizona. These reports have been developed to identify those needs for each community and provide the specialized care, interventions, and resources they may need. The Bureau of EMS and Trauma Systems collaborates and partners with these communities to prevent premature death and disability.
