I was recently reading a post from Dr. Amy that reminded me of the well known saying that patients judge doctors by the three A's:
In that order.
That is so true. In the outpatient rehab clinic in my residency, there were two physicians who were basically beloved by all their patients. They were intelligent, but they hardly had an encyclopic knowledge base.... but the patients adored them because they were just SO NICE.
One of those attendings wasn't particularly charismatic or outgoing. In fact, he was downright nerdy. But he was still loved by his patients (and me), because he was a total sweetheart.
That inspires me as a physician. Because I'm not charismatic and I don't think I ever can be. You can't learn charisma. And as a new attending, my knowledge base is probably less than encyclopedic. But I can certainly be nice.
