Update (25 Aug 2015) An error was identified in Table 7 and Table 9 of the Provider Level Analysis, where values suppressed as part of disclosure control were not included in the numerator for 'percentage within 4 hours' (table 7) or 'All - Sum' (table 9). Overall, a quarter of all providers listed were affected, ranging from minimal impact on most providers (less than one percentage point variation) to moderate impact on some smaller providers (up to twelve percentage points variation).

This is the 6th annual publication of the Accident and Emergency (A&E) Attendance data within Hospital Episodes Statistics (HES). It covers the period April 2012 to March 2013 and draws on just over 18 million detailed records of attendances at major A&E departments, single specialty A&E departments, minor injuries units and walk-in centres in England.

Publishing the A&E HES data enables initial conclusions to be presented for discussion and aims to promote and highlight the uses of this potentially rich data set. During the period covered by this publication, not all providers have completed data submissions and data quality is poor in some cases.

The publication also includes analysis of the A&E HES data compared to the NHS England Weekly Situation Reports (Sit Reps), the official source of A&E information, to highlight areas for further investigation.

NHS organisations can review their own data to ascertain the extent to which their local trend follows the national pattern. This can be done by using the accompanying interactive provider-level analysis file.


In 2012-13:

  • There were 18.3 million accident and emergency attendances recorded at major A&E departments, single specialty A&E departments, walk-in centres and minor injury units in England; an increase of 4.0 per cent from 2011-12.
  • Data is incomplete; there are 18.0 million attendances reported in A&E HES (excluding planned follow-up attendances), compared to 21.7 million reported in NHS England's Weekly A&E situation reports (Sit Reps) aggregate data for the equivalent period.
  • There are 189 providers with attendances recorded in A&E HES compared to 218 providers who have submitted A&E attendances via Weekly A&E Sit Reps. Weekly A&E Sit Reps receives data from a number of private providers, walk in centres and minor injury units that do not currently submit data to HES.
  • 42.8 per cent (7.9 million) of all A&E attendances were for patients aged 29 or under, 16.3 per cent (3.0 million) were for patients aged 20-29. Just under half of all A&E attendances (49.4 per cent) were male.
  • 23.9 per cent (4.4 million) of all arrivals at A&E were by ambulance or helicopter, compared to 24.2 per cent (4.3 million) of all arrivals in 2011-12.
  • 62.8 per cent (11.5 million) of all attendances at A&E had a valid diagnosis code and 13.8 per cent (2.5 million) of all attendances had a diagnosis of 'Diagnosis not classifiable' recorded.
  • 93.9 per cent (17.2 million) of all attendances had a valid treatment code. 34.4 per cent (6.3 million) of all attendances had a recorded treatment of 'guidance/advice only'.
  • 59.0 per cent (10.8 million) of all attendances were discharged ('GP follow-up required' or 'no follow-up required') and 20.8 per cent (3.8 million) of all attendances were admitted to hospital.
