Diagnostic Imaging Data Set (DIDS) implementation tools and guidance

The DIDS v2.0 TOS includes the data items and their definitions in DIDS v2.0

The ETOS shows the data items collected, their definitions and the validations which will take place when DIDS v2.0 data is received by NHS England. 

It includes the validations which would result in a rejection of the file or a warning on the data submitted. 

For more information see the worksheets ‘Validations – Data Items’ and ‘Additional File-Level Rejects’). 

The ETOS should be read in conjunction with the DIDS User Guidance, DIDS Data Model and DIDS Mapping Guidance.

It is likely to be most relevant to the providers of imaging services and system suppliers to help understand the validations in DIDS v2.0. 

This guidance compares v1.0 to v2.0 of the DIDS data set to show what changes have been made as part of the v2.0 update.

It provides a high level comparison of the data groups and data items in v1.0 and v2.0 of the Diagnostic Imaging Data Set to show changes between the versions. 

This guidance is expected to be useful for providers of imaging services, system suppliers and other stakeholders to familiarise themselves with the changes.

The DIDS System Conformance Checklist is a tool to help care providers assess how well their local IT systems map to the DIDS v2.0 Technical Output Specification.

The DIDS v2.0 Data Model shows each of the data groups and data Items that will make up a submission.

The DIDS v2.0 User Guidance provides more detailed guidance on how DIDS v2.0 should be interpreted by users, system suppliers and other stakeholders by providing information on each individual data group and its constituent data items.
