I'm a doctor. I've been to the American conference for my specialty a few times.
The Medicine that they practice is pretty terrible. Yes, there are no waiting times but people get a lot of unnecessary investigations - these all carry risks - radiation, finding something unexpected (an incidentaloma) that has no bearing on the condition being investigated and might never affect the patient but now it is known about affects everything - life insurance, driving licences etc.
They are often restricted much more than we are about what drugs to give.
My usual "recipe" of IV Paracetamol/ NSAID and Fentanyl for kids having a tonsillectomy raised huge eyebrows - Fentanyl is frowned upon because of it's addictive potential (and not amongst the kids!) and they can't get IV Paracetamol in the OR as it is "too expensive"...
The NHS has many faults but every time I go I'm mightily glad that I live and work here.
I had an accident last week - I was seen in ED that night, had sutures on my face and my wrist splinted. I got an MRI appt within 36hrs for my wrist followed up my a fracture clinic appt (with a consultant) and then a specialist physio appt. It was all free.
The ED team gave me clear instructions about how to get back in touch with them to initiate an ENT referral if my asymmetric nose wasn't due to swelling as we thought but was because it was actually broken!
All in all the service I received was amazing.
