It's been a long time, but I worked in a company with a call center in NC, and some support folks back in CA. We had some 'private pipe' between the two locations. I've no doubt it used 'public internet' connections along the way, but my recollection was it was somewhat separated, and we had some SLA in place. It wasn't pitched as "faster than the other internet", but I believe we had minimum ping times and minimum speed stuff in place, and when things were down we got some prioritized service (and probably some discount on the bill). It's been years, and I wasn't in the networking side of things, so I don't know all the details, but... I can't imagine hospitals that had a need for a certain level of network speed and availability couldn't contract for that already, and no doubt they'd pay more than home users any way (businesses generally already do).
