I'd imagine the proportion of "good" doctors might be about the same as good programmers, or good teachers, though probably exceeds the supply of "good" politicians.

Point is medical care is only as good as the quality of the "team" consisting of the doctor and the patient. It's a partnership, an expression of the doctor-patient relationship. Not every two people will form a natural team, after all, many marriages fail.

It's kind of a cliche, but still true, find a doctor you can work with, someone you can trust and relate to. More likely than not, that's the the definition of a "good" doctor.
