Improving Access to Psychological Therapies (IAPT) data set

The IAPT data set was developed with the IAPT programme as a patient level, output based, secondary uses data set which aims to deliver robust, comprehensive, nationally consistent and comparable information for patients accessing NHS-funded IAPT services in England.

This national data set has been collected since April 2012 and is a mandatory submission for all NHS funded care, including care delivered by independent sector healthcare providers.

How the IAPT data set is used

The IAPT data set provides a comprehensive national picture of the use of IAPT services in England and supports a variety of secondary use functions such as:

  • commissioning
  • clinical audit
  • research
  • service planning
  • inspection and regulation
  • monitoring government policies and legislation
  • local and national performance management and bench marking
  • national reporting and analysis
