Submitting IAPT data

All organisations that provide NHS funded IAPT services in England must submit data. This page explains the data you need to submit and how.

How to implement the IAPT data set

To assist new and existing users during implementation of the IAPT data set, please refer to the IAPT v2.0 implementation planning template which provides details of relevant activities during implementation.

You can also refer to the full implementation guidance available from the DCB1520 information standard. Section 3.5 contains a step-by-step guide for new and existing users.

Data required from 1 September 2020

The requirements specification, available from the DCB1520 information standard, defines the scope of the data set, what is required from providers and how NHS Digital will assess that a provider has complied with submitting the data to meet this legal requirement.

IAPT Data Set v2.0 – DCB1520 Amd 14/2019

Version 2.0 of the IAPT Data Set received approval from the Data Coordination Board to start collection from 1 September 2020.

The ISN and formal standard documentation for IAPT v2.0 is published on the DCB1520 webpage.

Update – 30 October 2019

A corrigendum has been published on the DCB1520 webpage to provide notice of corrections to version 2.0 of the Improving Access to Psychological Therapies (IAPT) Data Set. The corrections relate to:

  • inclusion of an Integrated IAPT-LTC indicator
  • correction to an error in the format listed for a data item
  • amendment to group notes for IDS004EmpStatus
  • amendment to UID for a data item

The updated Technical Output Specification, Data Model, System Conformance Checklist and SNOMED mapping documents, have been updated and published below that reflect these changes.

Pilot data guidance

Version 2.0 now contains all of the necessary data requirements for the Employment Advisers and integrated health pilots collections, so these requirements will no longer be detailed in separate specifications.

How to submit data via SDCS Cloud

The IAPT Data Set is changing its submission platform, from the Bureau Service Portal (BSP) to the Strategic Data Collection Service (SDCS Cloud), for version 2.0.

For information and guidance on the SDCS Cloud, including how to register for a user account and guidance on submitting data, please see the Strategic Data Collection Service (SDCS) Cloud web page.

IAPT Intermediate Database (IDB)

The intermediate database (IDB) is now available for download for IAPT v2.0 submissions from September 2020 data onwards.  Before submission, your data must be entered into the latest version of the IDB.  The intermediate database (IDB) is a tool which enables the collation of data for submission of the IAPT data.  It is a Microsoft Access database and data must be provided in this format. Once all data has been uploaded to the IDB, NHS Digital can extract the data as a whole and begin processing it.  For further information about preparing for submissions using the IDB, please see the IDB Guidance from the list of documentation provided in the 'Data required from 1 September 2020' section.

The database can only be accessed and downloaded from the NHS Digital Technology Reference Data Update Distribution (TRUD) pages.  Previously the IDB was available to users via the NHS Digital Contact Centre, however this is no longer applicable.

If you are not already registered on TRUD, you can register via the link on the TRUD homepage. Once registered, the IDB is located via the ‘data set development services tools’ link and new users will need to click on ‘licences’ which will enable a ‘download’ link to open.

Data quality

When you submit data to SDCS Cloud, the system generates a report describing the data quality errors and warnings present in your submission. 

In July 2020, we ran a webinar which explored data quality issues and provided guidance on how to improve data quality in your submissions.
