Accessing HES

The HES publications focus on headline information about hospital activity. Each annual publication includes a series of national tables and also provider-level breakdowns for some main areas.

All data items included in the published tables are explained in footnotes, and NHS Digital publishes data dictionaries for HES describing the format and possible values for all HES data items:

This data is also readily accessible via an online interrogation service (for NHS users) or via our bespoke extract service:

Further information about MSitAE

NHS England and NHS Improvement compiles A&E attendances and emergency admissions data through a central return that is split into two parts:

  • A&E Attendances: This collects the number of A&E attendances, patients spending greater than 4 hours in A&E from arrival to discharge, transfer or admission and the number of patients delayed more than 4 hours from decision to admit to admission.
  • Emergency Admissions: This collects the total number of emergency admissions via A&E as well as other emergency admissions (i.e. not via A&E).

The above data items are split by the following categories of A&E department:

  • Type 1 Department (Major A&E Department).
  • Type 2 Department
  • Type 3 A&E department / Type 4 A&E department / Urgent Care Centre

Detailed descriptions of the A&E department types can be found on the Introduction Section of this document.

NHS Trusts, NHS Foundation Trusts, Social Enterprises and GP Practices submit data to NHS England and NHS Improvement via the NHS Digital Strategic Data Collection Service (SDCS). The Strategic Data Collection Service (SDCS) is a secure data collection system which accepts uploads of submissions in a variety of formats. Once data is submitted and signed-off, NHS England performs central validation checks to ensure good data quality.

Data Availability

A&E attendances and emergency admissions data are published to a pre-announced timetable, usually every second Thursday of the month. The data is published on the NHS England website:


Data Revisions

Revisions to published figures are released on a six-monthly basis and in accordance with the NHS England Analytical Services (National) team’s revision policy:
