::You could also cover the skills needed as maybe many of the agency staff don't know what to expect and don't realise that it is not all fast-paced life & death action!::
Maybe not, but in my admittedly limited experience, it is
fast-paced admit, investigate, discharge/move to wards. If you're not up to speed with processing patients the non-stop machine that is A&E can be daunting. If you do happen to have a bit of fast-paced life and death action, you're still left with the backlog when it's over and that can be ultra-stressful in itself.
For what it's worth, I LOVED my placement in A&E while I was a student, and wanted more than anything to work there. The more experienced I get now as an RN, the less confident I am that I would cope in that environment. I think that says more about me than A&E though
