Redesigning your environment is hard and expensive so it's easy to see why hospitals and similar industries are so behind and vulnerable. BUT, given that important data needs to be backed up anyway, most commodity backup software and commodity storage platforms are sufficient to restore encrypted data. Even Windows shadow copying feature (which lots of storage platforms will expose snapshots/revisions as) is pretty sufficient to prevent significant data loss. So unless the ransom cost is cheaper than an IT tech reimaging/rebuilding the machine + compliance costs, it doesn't really make sense.
