I should really, really hope hospitals are not using routers like these.
Medical equipment more and more often has networked embedded software that can't be updated. They won't throw away a multimillion-dollar device just because it can't be upgraded from Windows XP.
I'll bet they still have service agreements for those devices though, even if the software is old. Consumer routers do not have support like that.
Oh, yes, they're usually still serviced- the systems are babied and locked down and generally taken care of, and if Microsoft releases an emergency XP patch I expect it would be applied. Still, there's a lot of old stuff floating around since medical hardware can last a lot longer than an OS support lifetime.
I'd expect a hospital has to have a pro-ish router due to the size of the network. However, I can easily see someone setting up some of these as a "temporary" fix just to get things working for some subnet. I totally expect some small clinics, independent doctors' offices, or EMS stations use devices like these.
I've worked in quite a few hospitals. I've got some really, really bad news for you.
