Not a physician myself, but both of my parents are, and are practicing.
They’re each a little different, and it entirely has to do with their personalities. My mom is a surgeon, and has a bit of “god complex” going on - to her credit, she’s a brilliant woman, but that also translates into “I can fix anything”.
So she doesn’t have a local PCP, she has the head of internal medicine in a major city as her PCP, who she sees infrequently. She also monitors her blood pressure, pulse, blood sugar, and cholesterol very often - the first three she does weekly, despite being normal in all three areas. She also religiously wears those tight support stockings, to avoid varicose veins. She eats extremely healthy, but she simply eats too much - think two skinless chicken breasts instead of one - , so she’s about 15 lbs overweight. She approaches all physicians she sees personally skeptically, and will cross check nearly all information, either privately or with another physician.
My father, on the other hand, is a good patient - listening to orders, asking questions when necessary, etc. I doubt he has a PCP; because both of them are specialists, they often feel a PCP is someone to lazy or too dumb to have a speciality
However, he would never let personal feelings get in the way of a procedure he needs - for example, instead of seeing any number of (very qualified) friends for a rotator cuff procedure locally, he traveled to Pittsburgh to have it done by the guy who does the Steelers.
Overall, they see someone who will deliver results, and this comes from simply knowing them and being in the environment. Lots of their friends have varying degrees of bedside manner - this doesn’t matter to either of them at all. They want someone whose results are stellar, who takes his continuing medical education very seriously. Bedside manner is a complete after thought to them.
Overall, a lot of the information they seek is completely test-based or very quantifiable. The physician may interpret it for them, but they will also interpret it for themselves. Being that both parties are highly qualified, this ends up being the same analysis. End of life care and such are entirely different issues they have yet to confront, but are the only things I can consider being an opinion they would seek or would potentially be different than their own in the future.
So how do I approach care? I’m 22, and don’t even have a PCP, though I see a variety of specialist whenever I need to, mostly the dermatologist and the gynecologist. I don’t look for the biggest name (since I’m getting routine care - for a special procedure, I would), but rather someone youngish, so they have more updated information. I approach all advice with a skeptical eye. I also note that when I tell a physician that both of my parents are practicing, they sit up a little straighter and give it to me with more medical jargon - and in turn, educate me a little more.
