Welcome
This is the website for the Diagnostic Imaging Dataset (DID) collection.
This website is where providers of diagnostic imaging tests to NHS patients in England will need to submit data on a periodic basis. This data will be an extract taken from their Radiology Information System (RIS).
The timetable contains exact dates of submission windows.
What is the Diagnostic Imaging Dataset?
The DID is a monthly collection of data on diagnostic imaging tests, extracted from providers RISs.
Read about the legal basis of this data collection.
By collecting data submitted to DID, NHS England is able to:
- provide accurate details on the specific imaging tests performed and the demographics of the patients at a national and sub-national level
- enable analysis of demographic and geographic variation in access to different test types and different providers
- assess effective delivery of care
- provide information on the utilisation of high value imaging equipment
- monitor trends in care and towards improving outcomes
- provide information to improve diagnostic services
- link to other data sets, most notably cancer registration data
Does my organisation need to submit this data?
If you provide diagnostic imaging tests to NHS patients in England, you need to submit this data. This includes; NHS trusts, NHS Foundation Trusts, and Independent Sector Providers who provide NHS funded diagnostic imaging tests.
However, please note that you are not expected to submit data on: breast screening services or any other diagnostic imaging tests not typically recorded on your central Radiology Information System (RIS).
In addition, if you are an NHS organisation that uses another organisation to perform a subset of your diagnostic imaging tests, you should ensure that either you or the other organisation (for example, an Independent Sector Provider or another NHS Trust) submit this data, to avoid gaps or double counting.
Data Standards Assurance Service (DSAS) gather feedback on central data collections from the colleagues who complete/submit returns. In particular, around the length of time data collections take to complete and any issues, suggested improvements or duplication of data collections. Feedback can given to standards.assurance@nhs.net
