Posturing vs. subtle murmurs or weird heart sounds is apples vs. oranges. EMT-b's can tell you when a pt. needs a CT from posturing.
True, I didn't mean to imply they were equal. That was a bad example on my part.
I was just trying to point out that the physical exam is important.
There's much better examples, but I'm too lazy to actually bother to think of any...
I think the echo was a good example of how technology is taking over the PE. The CT is the same way...in the ED you know the person has had a stroke...you could either do a full neuro exam and take 20 min to figure out exactly where the lesion is, and then send them to CT to confirm, OR you could just send to CT since you're going to do that anyway.
I was at the optometrist the other day, and they were checking my peripheral vision. Do you think that the tech stood in front of me, covering her eyes, and swinging her hand around in the "big H" confirmation? No, she stuck my head in a maching that had blinking lights. Did my optometrist use a ophthalmoscope as the exclusive means ot look at my retina? No...he took a picture of it, showing the entire field, and was able to look at it on a computer screen while he was showing it to me, too.
I'm not slamming the PE, it's just the previous poster is right--technology, like the Echo, is displacing it from useful practice. But that doesn't mean we shouldn't learn the techniques as well as anyone else has.
I didn't mean to say technology wasn't important. The PE is obviously less important in cases where you're going to refer the patient for a test regardless of doing a PE or not as in the stroke example you gave.
However, I wonder sometimes of how many technological exams are done that may not be necessary with a complete old fashion physical exams.
Obviously, an echo would be more accurate in an absolute sense relative to a cardiologist's exam. BUT, on a cost effective basis, a cardiac exam from the average cardiologist probably provides much more benefit per dollar than echos.
This gets back to the old question, which is a whole other thread, of whether or not a society wants to maximize benefit and that's it, or maximize benefit per dollar (which inevitably would lead to a lower amount of raw benefit relative to maximizing benefit only).
I've heard from various sources that physicians in England, where they have near the cheapest healthcare per capita on the face of the Earth, they haven't lost the importance of the physical exam, simply because the payor (the government through the NHS) restricts utilization so much.
Due to this, it's a necessity that they have good physical exam skills b/c there may not be the technology to back it up.
I've actually heard that it's a running joke with English doctors about how American doctors order CT scans for everything. Oh well, that's another thread too...
