Arizonans are feeling the effects of a doctor shortage that health care experts expect to worsen nationally in the next ten years. According to a report by the Association of American Medical Colleges, the nation will face a shortage of at least 46,000 physicians by 2025, and Arizona is currently 500 to 750 doctors short, said Dan Derksen, director of the Center for Rural Health at the University of Arizona. General access to medical care in rural areas and access to specialty care throughout the state are most affected by the shortage said Chic Older, executive vice president of the Arizona Medical Association.
