HES-DID Data Linkage Report, Provisional Summary Statistics, Apr to Nov 2015

Experimental statistics. A brief summary of the number of records in the HES (Hospital Episode Statistics) data set and DID (Diagnostic Imaging Dataset) that can be linked.


HES-DID Data Linkage Report - Provisional Summary Statistics, April to November 2015 (Experimental Statistics)


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 2015 to 30 November 2015 only. This is provisional 2015-16 data.
