Mental Health Services Data Set

The Mental Health Services Data Set (MHSDS) contains record-level data about the care of children, young people and adults who are in contact with mental health, learning disabilities or autism spectrum disorder services.


What is the Mental Health Services Data Set?

The Mental Health Services Data Set (MHSDS) is a change to the Mental Health and Learning Disabilities Data Set (MHLDDS) standard, which supersedes and replaces this and the following standards:

  • ISB 1072 Child and Adolescent Mental Health Services (CAMHS) data set
  • ISB 1509 Mental Health Care Cluster
  • ISB 1078 Mental Health Clustering Tool

MHSDS also incorporates requirements in support of Children and Young People's Improving Access to Psychological Therapies (CYP IAPT), elements of the Learning Disabilities Census (LDC) and elements of the Assuring Transformation (AT) Information Standard.

The MHSDS is a patient level, output based, secondary uses data set which delivers robust, comprehensive, nationally consistent and comparable person-based information for children, young people and adults who are in contact with Mental Health Services. As a secondary uses data set it intends to re-use clinical and operational data for purposes other than direct patient care.

The MHSDS is unique in its coverage, because it covers not only services provided in hospitals, but also in outpatient clinics and in the community, where the majority of people in contact with these services are treated. It brings together key information from the mental health, learning disabilities or autism spectrum disorder care pathway that has been captured on clinical systems as part of patient care.

The MHSDS key messages [77kb] (Opens in a new window) provide the core information about the data set.

SCCI0011 Information Standard

Version 1.0 of the MHSDS (Amd 12/2015) was accepted as an Information Standard by the Standardisation Committee for Care Information (SCCI) and an Information Standards Notice (ISN) was released in July 2015. MHSDS v1.0 commenced collection from January 2016.

Subsequently to this release, a small number of changes were required and v1.1 (Amd 68/2015) was recently accepted with an ISN being released in February 2016. Data collection for MHSDS v1.1 will commence April 2016.

The associated ISN's and standard documentation can be found on the SCCI0011 Publication page.

Submission of MHSDS data is mandatory for NHS funded care, including independent sector providers. As part of scope changes introduced in Amd 3/2013, data for clients who are wholly funded by any means that is not NHS, can now be submitted on an optional basis.

Organisations falling with scope of MHSDS should make monthly submissions via the Bureau Service Portal on Open Exeter.

Read how to submit data to the MHSDS.


How is the Mental Health Services Data Set used?

MHSDS 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 benchmarking
  • national reporting and analysis

The MHSDS is the data source used for the implementation of Mental Health Currencies and Payment (formerly PbR). As such, the Mental Health Care Clusters, and Mental Health Clustering Tool are implemented through the MHSDS. MHSDS is also planned to be the future source of the Learning Disabilities payment system once requirements are determined.

MHLDS statistics are for anyone wanting a comprehensive national picture of the use of specialist mental health, learning disabilities or autism spectrum disorder services in England, including:

  • policy makers
  • commissioners
  • mental health service users
  • members of the public
