Damn your constant use of aposiopesis, always leaving me wanting more...
EM and preventative medicine are two completely different mindsets, to the point that I'm not sure that they can co-exist in one person. EM is about moving the meat; hospitals do not advertise about the quality of care in their ERs, they advertise about the 8 minute wait time.
In comparison, my defining experience with a preventative doc was as a captive audience member at one of the many AF CME boondoggles. He was an O-6 colonel who was proudly showing all of us captains and majors his grand new questionnaire for the annual PHA (Periodic Health Assessment) that he was trying to get implemented Air Force wide. The thing was an unwieldy computerized module with more than a dozen screens with at least 10 questions apiece per screen. All told, there were more than 400 questions, ranging from family health history to what kind of learning style the member preferred (audio? visual? osmotic?), all of which he wanted the clinician to go over with each patient during the visit, every year.
I raised my hand and asked if he'd timed how long it took to fill out. He cheerfully replied that when everything worked, about 55 minutes. And that's just madly clicking away, with no positive answers requiring further elucidation. I then asked how a typical flight surgeon could accomplish this, since a light day in the clinic has at least a half dozen PHAs (plus the rest of the regular patient visits). He glared at me, and gave me a short, gruff answer that amounted to that that wasn't his effing problem. In a somewhat suicidal gesture, I then asked what all this data was going to be used for. He replied that it was going to be analyzed and that question time was over.
