The state of Texas defines telemedicine as a remote health care service in which a physician may assess, diagnose, consult, treat, or transfer medical data using technology. It is a convenient, affordable way to access health care services, and recent advances in audio-visual communications technology are enlarging the potential of telemedicine to reach more people and address a growing number of health care needs. More importantly, this service could increase access to health care in more than 90% of Texas counties that are designated health professional shortage areas or medically underserved areas.
