At least, in the case of an "incident", and the finger being pointed at "lack of maintenance" (often so easy to blame, rather than the likely
actual reason), "they" can't say they didn't know (they weren't in effect warned)!
To my mind the Risk Register is a good thing. If I were in charge (at any NHS Hospital ... Heaven forbid), I would get as much as possible on that list! Let the Big Shots be made aware. Let them shoulder the responsibility. That's why they
gouge those excessive remuneration packages!

As an addendum: when I have been working as an agency tech, I have always advised the biomed manager to have the fact that I'm around placed squarely on the Risk Register. After all, there is
always risk, and it works in both directions. For reasons that I have never understood, they have always taken the view that it wasn't necessary. Perhaps they have been worried that I would sue the Trust in the event of picking up some awful
bug or some such thing. And the fact that I was on the Risk Register would prove that I was indeed there, which otherwise could be denied. Who knows? Is adding a risk to the Register such a big deal? Is it seen as an admission of
weakness ... or what?
