The information requested has been placed in the Library. The NHS Information Centre's Hospital Episode Statistics (HES) data have been used to show the number of accident and emergency (A&E) attendances in 2010-11 and 2011-12 where patients waited more than four, eight, 12 and 16 hours. Full year HES data are not yet available for 2012-13. Therefore, information collected by NHS England for 2012-13 has been used to show the number of patients waiting more than four hours in A&E. However, this data set does not break down the number of patients waiting more than four hours into the categories requested.
