As physicians and patients embrace the use of technology in health, physicians are increasingly using various forms of electronic communication to interact with their patients. In fact, many patients prefer having the option to communicate with their physicians via email, text, or electronic messaging through a patient portal to receive test results, refill prescriptions, and obtain medical advice for non-emergent care.
