My dad is a doctor (who felt it necessary to go over every trial he has helped run). They do discriminate explicitly on race (as well as other factors). Saying that this racial discrimination is biological is equivalent to saying that their are significant biological differences between the races. Although this is true in some cases (mostly genetic diseases), more often race is relevant as a proxy for social and cultural positioning. In practice, I suspect that if racism was stamped out of society at general, then there would be no medical benefit to racism in medical desisions.
