I believe residents need to have an attending sign off on everything they do, so while they could increase premiums indirectly, I don't know by how much. If anyone is named in a lawsuit, I think it would be the attending since the buck stops with them, and they should carry their own malpractice insurance in addition to the hospital's. Based on what I've read, I suspect residents are very profitable for hospitals, even if they use a significant portion of the grant.
