Can't really see what you're getting at with this one, Roman. Patient delays because kit is "down"?
In any hospital, there is always a lot of kit, and a lot of staff. So the opportunities for "messing up" are many and various.
Some users have "pride of ownership" of their equipment, others are careless. So, what else is new?
But that's why the biomeds are there, to put things right.

Or are you referring to users fiddling about ("experimenting", even) with the kit, and biomeds (so-called) who leave a trail of destruction wherever they go? Yes, I've encountered both in my time. I was usually able to sort out the biomeds, but the user problems were not always so easily dealt with.
