That’s something else that worries me. When my brother was in the ICU for a few weeks, near death last year*, one thing that bothered me was the way that nurses were rotated. It seemed that rather than keep a relative few caring for him, who would then have more consistent interaction with him, and more “hands on experience” with his case, the hospital rotated through so many we could not keep track of them. And, more often than not, if we had a question, the nurse did not know, would have to go check with someone or something, etc. The caregivers all seemed very compassionate and caring, and they did pull my brother through, but, well, it was disturbing, and frustrating for the family.
Later, when my brother was in rehab, he pretty much had the same nurses and other caregivers seeing him from day to day.
At any rate, my brother was not deadly infectious. In the case of a deadly infectious disease, having a large number of people in contact with the patient just seems nuts...
some nurses work 12 hr shifts others work 8 and there is lots of overtime....
there is not going to be continuity....hospital care is 24/7 and it doesn't relate to bankers or teachers hours....
