Evolution isn't relevant to how well they diagnose or treat patients

It might bear on their grasp of biology. As I just said above, an empirical study of medical personnel, their "take" on evolution, and competence measures, would be interesting.

Until then we'll just have to disagree on what the results of the study would be.

Belief in evolution has no impact on one's study of human anatomy, pathology, physiology, histology, biochemistry, etc.

Learning the Kreb's Cycle depends in no way on what you think about evolution.

Learning about the complement cascade requires no knowledge of, or belief in, evolution.

And so on...
