Summary

This is the latest statistical publication of linked HES (Hospital Episode Statistics) and DID (Diagnostic Imaging Data set) data held by the Health and Social Care Information Centre. The HES-DID linkage provides the ability to undertake national (within England) analysis along acute patient pathways to understand typical imaging requirements for given procedures, and/or the outcomes after particular imaging has been undertaken, thereby enabling a much deeper understanding of outcomes of imaging and to allow assessment of variation in practice.
 
This publication aims to highlight to users the availability of this updated linkage and provide users of the data with some standard information to assess their analysis approach against.
The two data sets have been linked using specific patient identifiers collected in HES and DID. The linkage allows the data sets to be linked from April 2012 when the DID data was first collected; however this report focuses on patients who were present in the either data set in the period 1 April 2014 to 31 January 2015 only. For DID this is provisional 2014-15 data. For HES this is provisional 2014-15 data.
 
The linkage used for this publication was created on 7 May 2015 and released together with this publication on 5 June 2015. The linkage utilises all historic HES patient identifying data up to 30 April 2015 and all patient identifying DID data submitted prior to 28 April 2015

Key Facts

• Just over 32 million Imaging procedures were recorded in the Diagnostic Imaging Data set as having taken place during the period 1 April 2014 to 31 December 2014, it was possible to link 29.5 million of these records to individuals in the Hospital Episode Statistics data set.
• Just over 5 million patients  who were admitted to hospital at least once during the period were identified as having at least one imaging procedure during the same period
• 5.8 million patients who had at least one accident and emergency attendance during the period were identified as having at least one imaging procedure during the same period
