My doctors can communicate asynchronously through the MyChart app/website (the app is fairly terrible, I would rather them just use email, but oh well) where I can read and respond when it makes sense for me. Any test that they are running where the results could be bad is already asynchronous (or I am in the hospital) so delaying a few hours in reading it doesn't seem like a big deal even if it is something bad.
Email can be unreliable and slow.
_they_ call _me_ with ideas on how to get me to pay them; when i go in, my vitals are strong
But then I remembered that most people here are Americans, and you (if you're American, I'm assuming here) don't go to the hospital/doctor just because, as it costs so much, compared to the life I'm used to, where whenever there is a health worry, you go to the doctor/hospital and they say "don't worry, it's fine" most of the time.
