Although there is a specific exemption in the HIPPA rules for radio communications, that's what cell phones are for, or the encrypted medic-to-hospital TG's.
But you don't give names out, or other personally identifiable information, in the first place. Even on the old UHF EMSCOMM channels. Go watch episodes of, "Emergency!". It was always gender, age, and medical complaint, followed by vitals, even in the late 60's and early 70's, when paramedic programs first started.
