This, so much this. My father died due to post-op complications from a knee replacement surgery. Before my Mom died, her nurse told me that she "can't believe she's doing this. She feels like she just got out of school and doesn't know enough to be doing this sort of thing".

Their processes have become point and click. They don't really know what they're injecting or why they're doing it. At this point, the doctors only care so much as well. Avoid hospitals whenever you can. Things have changed drastically.
