The Diagnostic Imaging Data Set was introduced by ISB 1577 Diagnostic Imaging Data Set, in response to the lack of detailed data on national data on Diagnostic Imaging tests for NHS PATIENTS. The original requirement came from the cancer strategy to improve GP direct access to certain Diagnostic Imaging tests, as a method was required to monitor implementation of this policy.
The Diagnostic Imaging Data Set, however, has many benefits for example, to:
- Provide NHS data on GPs’ direct access to tests, as well as tests requested via other referral sources. Benchmarking data will be fed back to GPs and, where appropriate, used to encourage increased use of tests, leading to earlier diagnosis and hence improved outcomes
- Provide more detailed NHS data than is currently available on test type (modality), body site of test and PATIENT demographics
- Enable analysis of turnaround times for tests
- Enable better analysis of cancer pathways by linking the National Cancer Registration and Analysis Service data to Diagnostic Imaging test data for cancer PATIENTS
- Allow Public Health England (PHE) to calculate more accurate estimates of the distribution of individual radiation dose estimates from medical exposures.
From April 2012 it became a mandatory requirement that all providers of NHS-funded Diagnostic Imaging tests for NHS PATIENTS in England submit the central Diagnostic Imaging Data Set on a monthly basis.
The Diagnostic Imaging Data Set facilitates the collection of clinical data and the sharing of such data to underpin the delivery of effective Diagnostic Imaging. It is structured around the clinical processes of local Radiology Information Systems (RISs) used by NHS Trusts and NHS Foundation Trusts. It records administrative data relating to Diagnostic Imaging test ACTIVITY.
Information is collected relating exclusively to Diagnostic Imaging test ACTIVITY. The Diagnostic Imaging Data Set describes Diagnostic Imaging tests that have taken place as part of a broader PATIENT PATHWAY. This includes PATIENTS referred from within the ORGANISATION, either as an out-patient, in-patient or from Emergency Care Department, or referred directly from their GP or another Health Care Provider.
The Diagnostic Imaging Data Set is collected from NHS funded providers of Diagnostic Imaging test SERVICES and submitted via a portal on the NHS England website. The submissions are processed and aggregate extracts are produced for provider and commissioner ORGANISATIONS and national groups such as the Department of Health and Social Care and Public Health England. This also allows linkage to the National Cancer Registration and Analysis Service.
Please note that the collection of the Diagnostic Imaging Data Set does not replace any other collection of diagnostic data such as the Diagnostics Waiting Times and Activity Data Set (DM01), which should continue to be collected.
Data Set Order
- The transmission order of the Diagnostic Imaging Data Set is different to the order of the items in the NHS Data Model and Dictionary and XML Schema.
- Please see the "Guidance Notes" at: Diagnostic Imaging Dataset: Guidance for Data Submitters, which contains a full list of Diagnostic Imaging Data Set fields in the order they are submitted.
- Work is planned to amend some of the Diagnostic Imaging Data Set items and when this is approved by the Data Alliance Partnership Board (DAPB), the NHS Data Model and Dictionary will be updated to match.
The Mandation column indicates the recommendation for the inclusion of data.
- M = Mandatory: this data element is mandatory and the technical process (e.g. submission of the data set, production of output etc) cannot be completed without this data element being present
- R = Required: NHS business processes cannot be delivered without this data element.
