> Can you give some examples of how other modern countries use telehealth and similar technologies as the basis of their provision of affordable universal healthcare?
In BC, Canada, there is the 24/7/365 BC Nurse's Hotline. (Healthlink BC)
It's a phone number, that you can call, to get medical advice.
"I have peanut allergies, and I am having an allergic reaction to peanut butter. I've taken my emergency pills for it, and I have an epipen with me. My symptoms are such and such. It's 3 am, and I'm at a provincial park's parking lot, 20 km out of town. Should I inject myself? Should I wait it out? Should I drive myself to the hospital? Should I call an ambulance?"
The practitioner at the other end will, given the information presented, provide medical advice.
The American reaction to this situation would be to go straight to the ER, regardless of whether or not they actually need it.
PS. In the exact situation I described, the person in question was told that someone should drive them to the ER (It turned out that they would have died, if they hadn't.) But, people call the BC nurse's hotline for all sorts of reasons, many of which do not necessitate a trip to the hospital.
