So when should you seek a different hospital than your nearest - or your usual?

Here's research from Germany suggesting its when occupancy touches 92.5%:http://www.health.jbs.cam.ac.uk/research/current/downloads/120806_stress_on_the_ward.pdf

Any research into what the exact figure is for the USA or UK or India or any other country?

If so, I'm unaware of it.

But occupancy rates are one thing to keep in mind anyway....
