I think the concept of making hospitals more patient friendly (ie, less sterile and cold) is a good one, and most hospitals can be redesigned to make them not only more patient friendly, but more nurse/healthworker friendly as well. A hospital is, afterall, supposed to be a place to heal.
That said, I think that much of what is thought to help healing, like music and unlimited visiting, can actually be a hindrance. In the NICU, for instance, we always had unlimited parental visiting, and then some parents would get upset when asked to step out at change of shift. Or sometimes did not understand the need for limited stimultion of a very sick infant. Or they wanted to bring 10 family members in at the same time, including a toddler with a runny nose.
I think much can be done to make the hospital a more desirable place for both staff and patients--made more comfortable, aesthetically pleasing, and more efficiently organized to make the nurses job easier--but stuff like a grand piano, or giving patients forbidden foods is just ludicrous.
