Funny that we know so much, but the human side of the equation is missing. We act as though we are treating machines instead of people in the hospital. Things like bed comfort and ambience are not considered. In the US, there is also a billing issue. So much of hospital practice today revolves around what Medicare/Medicaid and insurance industry will pay. We, the patients, aren't aware of these rules so we don't know when our protocol is adjusted by consideration of payment. But this is a compelling factor for hospitals (and many doctors).
Thanks very much for the insightful comment.
