A Surprising Discovery And The Value Of The Physical Exam
I’ve remarked in the past how rarely I ever learn anything useful from physical exam. It’s one of those irritating things about medicine — we spent all that time in school learning arcane details of the exam, esoteric maneuvers like pulsus paradoxus, comparing pulses, Rovsing’s sign and the like. But in the modern era, it seems like about half the diagnoses are made by history and the other half are made by ancillary testing. Some people interpreted my comments to mean I don’t do an exam, or endorse a half-assed exam, which I do not. I always do an exam, as indicated by the presenting condition. I just don’t often learn much from it. But I always do it.
The other day, for example, I saw this elderly lady who was sent in for altered mental status. There wasn’t much (or indeed, any) history available. She was from some sort of nursing home, and they sent in essentially no information beyond a med list. The patient was non-verbal, but it wasn’t clear if she was chronically demented and non-verbal or whether this was a drastic change in baseline. So I went in to see her. I stopped at the doorway. “Uh-oh. She don’t look so good,” I commented to a nurse. As an aside, this “she don’t look so good” is maybe 90% of my job — the reflexive assessment of sick/not sick, which I suppose is itself a component of physical exam. But I digress. Her vitals were OK, other than some tachycardia*. Her color, flaccidity and apathy, however, really all screamed “sick” to me. Of course, the exam was otherwise nonfocal. Groans to pain, withdraws but does not localize or follow instructions. Seems symmetric on motor exam, from what I can elicit. Belly soft, lungs clear. Looks dry. No rash. Read more »
