They are almost certainly MOVs. Shunt mode surge suppressors (MOVs) on
branch circuits are a very bad idea -- If equipment plugged in at those
outlets are connected to anything plugged in at a different outlet, the
differential voltage between the green wires can blow up that equipment in
the event of a strike.

I agree. Hospital grade outlets are a good thing. But buy them without MOVs.
