Nope, soon to be American grad here that is going into EM. I'm talking about a patient that has a history of migraines (and this headache is just like that), is young, not "worst headache of my life," no focal neuro deficits or papilledema, no history of headaches worse in the morning, not obese etc. During my EM rotations those patients wouldn't get an LP or imaging, simply a headache cocktail and time . Don't get me wrong, most people get scanned or LP'ed but there are some occasions when it's not indicated. There are risks and it costs money. As someone that had a CT that wasn't indicated earlier and a few months later got a bill for $5000 because insurance refused to pay. I think that doing no harm bit includes to a patient's pocketbook. At the end of the day, I'll write it down because it's fake and I just want to pass. So stop with the condescending tone about "in America we do it the right way." Not true, we do it the way that prevents us from getting sued and without regard to the cost. No wonder health care is so expensive...
