I don't know that anyone is using the HEAR system for hospital notifications. At least not in Region 2. Med 4 is repeated because it's the statewide hailing channel. As I recall, and it might have changed, the Med 4 receivers don't have PL, although the transmitters do.
In general, the Med channels are not repeated. The original system design, going back to the 1970s, was for the Med channels to operate in full duplex mode. That's why they aren't repeated, even though there is no full duplex operation and hasn't been in close to 30 years. You will hear the hospital side (463.xxx), but generally will not hear the mobile side (468.xxx) unless you are right on top of them.
Franklin is right on the edge of Region 2, but often goes to hospitals in Region 4 or Region 5. If you weren't using PL, then you might have been getting a Region 4 tower. I think Med 8 is Region 4, at least some towers is still repeated. The reasons for that also go back to the 1970s and I won't bore people with them.
If you go to
https://www.cmemsc.org/, there is a lot of information on how the Region 2 system works and where the towers are located.
You didn't say where you are listening from, so I don't know what tower might be closest to you.
