You're referring to a nurse practitioner (NP), and the key thing is they can prescribe medication, so, if you need prescription strength cough medicine or something like that, they're great! However, if you have something strange that you'd need a medical savant like Dr House to diagnose, they're no good, so they'll confer with MD colleagues and follow up. But also, Dr House is a fictional doctor and no doctor is that good. (If you know of a specialist that
is, I've got a friend with a chronic pain disorder that needs help.)
Having a medical professional on tap - I've never had to wait more than 15 mins to see someone virtually - is great and well worth the price of admission of you can afford it (couple hundred a year). Virtually is great because if you're sick, the last thing you want to do is leave the house, but they also do in person visits as well.
They also have the facilities to do blood draws and give vaccines.
Hope their new owner (Amazon) doesn't mess things up.
