Ms Louise McGirr:

There are different reasons for that. Operationally, Mr. Gloster and Ms Hoey will have a strong view on it. There is a reliance on agency. There are incentives for agency in terms of its costs. There are rostering issues around it. There is a need for it, of course, in terms of some of the high levels of activity and demand. There is a whole range of different factors. Different hospitals approach it differently.
