I believe that the main problem is the length of time it takes to carry out the assessment stages. Gerrish found assessment time-consuming and Cardiff took 8 hours to carry out the assessment stage. The patient in A&E needs to be assessed immediately and quickly. Admittedly, patient who are moved into the crash room are with a nurse longer and,there for, ther is more time for a more detailed assessment, but initially even these patients have to be assessed speedily.
