Mr. Damien McCallion:

Yes, we have a national policy on risk assessments and Dr. Henry might want to comment on that also in terms of how it is applied. That national policy is worked down through the system on a daily basis where decisions are made in terms of risk, because it is important it is not just a technical process.

Separately, the operational management teams in every hospital will look at it. As I said, at a formal level, they will look right across the whole hospital on a regular basis. Dr. Henry may wish to add to that reply.
