Patient transfers from wards to ICU

Hi

I am doing a survey on the hospital trasnfers and would like to know the basic transfers of patients in a hospital when he firsts visits the hospitals. I would like to know that are there any chances of patients shifted form wards to ICUs? If yes how many and why?
If I understand the question correctly, a patient would be transferred from the regular floor (ward?) to ICU when their condition worsens and they meet the criteria for ICU status.There is no way to answer "how many."

What country are you from? What do you mean by transfer to the ICU it is impossible to get an exact number....are you a student?
