Dave, I am not aware of any 'before and after studies' of Equipment Library usage. If there are any I would like to know as well. I think that these studies, if any, will have been done in-house by each hospital to find out if they have been cost effective or not.
Writing from our experience, we have all Infusion devices and Dynamic pressure mattresses controlled via an EL. That way we have the best cost effective system of using the 'limited' resources that we have.
You will certainly need space for every item as demand for resources fluctuates.
All I can say is that here, the prevailing viewpoint is that the hospital cannot do without our EL even with the limited resources that they give us to run it.
I have written reports for the hierarchy here in the past regarding the present functioning of the EL and how 'efficient' it is, but I am not sure that is what you are after. As I stated, I think the 'info' you need will have been written on an individual hospital by hospital basis.
