Yes. These are common as muck. Remember clinical staff aren't like the rest of us office bound nerds. They don't have desks, they don't have computers, they probably can't even remember their corporate email login. What they do all have is Facebook and a smartphone, so a Facebook page becomes the official corporate comms tool.
Daft, but that's how it is in wards up and down the country because there's simply no alternative.
