Telemedicine also includes a standard doctor's office visit, with the notable difference being that the doctor is in his or her office and the patient is at home. Using a computer, smartphone or tablet, the patient signs in on a website at the time of the appointment. Doctor and patient can then see and hear each other on their screens. It's like having a chat on FaceTime or Skype. In the case of virtual office visits, the software used for the video conferencing must comply with strict standards of security and confidentiality.
