Yes and there is an added benefit to frequent interruptions: despite all the monitoring equipement, a human assessment can go a LONG way in detecting trouble. My wife used to be an ICU nurse and her first code (CPR) in her career was when she was doing some routine stuff for the patient and noticed the color of their skin "looked different". When the patient's heart stopped beating, she was already there to get it back going, saving some precious delay.
For non-ICU stuff, yes there could be some better coordination around sleeping time, but again there's so much non-verbal stuff going on in just a physical assessment.
What would really be useful is having cleaning services and admin/billing services come at the same time (well, right after) a nurse comes, to take advantage of that interruption.
