One could make that argument in a hospital environment, but eventually patients go home. While they're at home, some telemedicine might save their lives. Should we expect e.g. pacemaker patients to know how to set up a VPN? Or maybe you're just saying that pacemakers must be controlled through direct contact only... that's on the device designers then, not on local network admins.
Yes, it should be direct contact. Even short range wireless would make me nervous without guarantees that it was just one way monitoring. I wouldn't blame network administrators for the safety of a device that should have never been on it in the first place.
