For the 2011-12 financial year, Hospital Episode Statistics (HES) has collected 91 million records detailing outpatient appointments by NHS hospitals in England or performed in the independent sector, and commissioned by the English NHS.


Outpatient HES data was collected for the first time in 2003-04. The Health and Social Care Information Centre first released outpatient data at the end of July 2006 and the data was originally released on an 'experimental' basis. Since then, the experimental label has been removed and in 2008 the outpatient published tables were accredited as a National Statistic. This means the data within these specific tables has been produced in accordance with the 'Code of Practice for Official Statistics'.


For the third year we have produced provider level analyses, to contribute to the improvement of both the quality and coverage of outpatient data submitted to HES. It is hoped this will stimulate discussion and ultimately contribute to enhancements in patient care.


To fully realise the advantages, the quality and coverage of the HES outpatient data needs to be improved with the support of providers throughout England. Provider level information is available in the supporting Excel document, 'NHS Outpatient Statistics: Provider Level Analysis, 2010-11 to 2011-12'. This presents information at national, strategic health authority, hospital provider (where submitted) relating to:

  • type of attendance and sex

  • type of attendance

  • attendances by age

  • non attendances by age

  • first attendances by source of referral

  • first attendance by outcome

  • first attendances from patients referred by General Medical and Dental Practitioners by time waited

  • selected main specialties


In 2011-12 there were 91.0 million outpatients appointments, of which 70.3 million (79.8%) were attended

  • Patient and hospital cancellations were similar, 6.1% and 6.3% respectively of all appointments

  • 6.8 million appointments (7.5%) were not attended

  • While the total number of appointments has increased year on year, the proportion of attendances has remained relatively constant since 2007-08 

  • The greatest number of outpatient appointment was for patients in their 60's, accounting for 11.4 million or 15.8% of all attendances
