But I agree that for some appointments it obviously doesn't work because you can't examine the patient or take vitals the same way/at all.
Call me new-fashioned, but I don't want to spend a few hours of a workday several times per year to see a doctor for less than 5 minutes for prescription refill for a drug that I have been taking for years.
Why in the world would either of us need to see each-other in person when he can ask me the same 3 questions he always does over the phone?
For certain things, like common illnesses, it is pretty good.
But that being said, use caution. I had something minor turn into an ER visit because I used telemedicine instead of going to my GP. Telemedicine prescribed antibiotics, which was correct, but GP would have done a drain too. Lack of drainage caused uhh unpleasant problems down the road.
