Cost-effective health care services are being delivered to many rural and urban populations in Arizona by telemedicine. Today, radiology is available 24/7 in many rural communities, an unprecedented level of service. This helps keep patients in their local communities for the health care and contributes to the survival of rural hospitals. Obtaining appointments with dermatologists can take months in Tucson and Phoenix but are available the same week in rural communities using telemedicine. Mental health services are now widely available throughout greater Arizona using telemedicine. Numbers of telemedicine cases are increasing at a rapid rate.
