If you’re going to Mayo Rochester, your hands-on stuff like that is limited.
There are special teams of technicians for most all of those. It improves individual patient care experience, but doesn’t do much for individual physician skill training; except the decision making process of when, and when not, to order this and that medical intervention.
Besides, you mostly wear a suit all day long, so who wants to get that dirty, when there is a team for scut work. It allows you to go on to the next patient instead of getting bogged down by blood draws and such.
Don’t kill the messenger, that’s just the flavour of the place.
