Coming from the United States' health care training system one of the most noticable things about the Swedish medical education system is the absence of a hierarchy. This produces a much more open environment in which to work and allows for, I think, much more fun and educational interactions between student and attending. There is an open dialogue between all involved in delivering care that does not exist in the US.
(I did not participate classroom/theortical teaching and thus cannot comment on the relationship between what is thaugh in the classroom and what one sees in the hospital).
