What data are in HES?
HES has details of all NHS admitted patient care, outpatient appointments and A&E attendances in England. It includes private patients treated in NHS hospitals, patients resident outside of England and care delivered by treatment centres (including those in the independent sector) funded by the NHS.
Each HES record contains a wide range of information about an individual patient admitted to an NHS hospital, including:
- clinical information about diagnoses and operations
- information about the patient, such as age group, gender and ethnicity
- administrative information, such as time waited, and dates and methods of admission and discharge
- geographical information such as where patients are treated and the area where they live.
It contains admitted patient care data from 1989 onwards, outpatient attendance data from 2003 onwards and A&E data from 2007 onwards.
NHS Maternity Statistics were previously produced and published by the Department of Health. Earlier versions can be located on their website. The NHS Maternity Statistics 2003-04 Publication is also available online.
HES is a rich and detailed data set and we publish a number of standard analyses. You can download published data tables and analysis from our data catalogue.

Outpatients - December 2015
Accident & Emergency - January 2016
Exact dates will be given on the Publication Calendar closer to the date according to usual National Statistics processes
Monthly topic of interest
To accompany the provisional monthly publication, each month we produce a topic of interest which focuses on an area of the HES data. This might be a disease or cause of admission to hospital, and typically presents information for two 12-month periods.
Users are welcome to suggest future HES topics of interest by emailing email@example.com
Data Access Request Service
Given the huge number of combinations of fields within HES, it is only possible to publish a limited number of analyses. If you can't find the data that you need in the catalogue, our Data Access Request Service may be able to help. The service provides a range of standard and bespoke extracts and can also link HES to other sources of health data to give a wider picture of health and well being.
Patient Reported Outcome Measures (PROMs)
Patient Reported Outcome Measures (PROMs) measure quality from the patient perspective. Currently covering four clinical procedures, PROMs calculate the health gain after surgical treatment using pre- and post-operative surveys.
