If the management cannot manage the devices, then (by definition) management has failed.

It sounds to me like these hospitals you are talking about need to get a grip!
Meanwhile, here's an idea:- let the patients
buy the kit they need; then they can do whatever they want with it.
PS: at one place I worked a few years back patients used to come in every now and then for "follow up". They had to bring their CPAP etc. devices with them. One of us used to go along and attend the session to check out the devices - functional check, filter changes and so forth. Surely the clinical staff can manage something like that?
