It's a necessity, a side-product of not having anywhere near enough nurses, assistant staff and doctors in hospitals. They're juggling alarms constantly (which have to blare in a cacophony) and speed from one patient to the next.

Ideally you'd have a 1:1 (or better!) assignment between a single patient to a single nurse in critical care, 1:3 for patients that can't move around on their own (and thus need more assistance, even if it's just helping them to eat or go to the loo), and 1:5 to 1:10 for everyone else. The sad reality is that even in Germany, you have care home staff calling in the fire department to assist because there were just three staff in a night shift, having to deal with 170 patients.
