Telemedicine is good if it's narrow in scope. I do it for a very specific disease process where I prescribe only 1-2 medications. The telemedicine consult is scheduled for 3 minutes, and pays $8. I typically have about 20 patients show up per hour, which is $160/hour. I review their labs which is another $20 per patient on top of that. After that it's a lab review every 3 months for another $20. My hourly after all the prescriptions signed is comparable to what I make per hour in EM.
So far it's been doing well. Would definitely not do any tele-medicine for general medicine, or ED medicine unless there was a hefty hourly guarantee. Dealing with telemedicine hypochondriac patients is even worse than in real life, because generally they have an online message center they can contact you from over and over.
