The Mental Health Services Data Set (MHSDS) is a PATIENT level, output based, secondary uses data set which aims to deliver robust, comprehensive, nationally consistent and comparable person-based information for children, young people and adults (including elderly people) who are in contact with specialist secondary Mental Health Services located in England, or located outside England but treating PATIENTS commissioned by an English Clinical Commissioning Group (CCG) or NHS England specialised commissioner.
As a secondary uses data set, the Mental Health Services Data Set re-uses clinical and operational data for purposes other than direct PATIENT care and defines the data items, definitions and associated value sets to be extracted or derived from local information systems.
- A mental illness
is within scope of the Mental Health Services Data Set.
- If the care is wholly funded by the NHS: the data submission for that PATIENT is mandatory
- If the care is partially funded by the NHS: the data submission for that PATIENT is mandatory
- If the care is wholly funded by any means that is not NHS: the data submission for that PATIENT is optional.
- The data submission is optional.
The Mental Health Services Data Set is used across the range of Health Care Providers and Organisations that provide specialist secondary mental health and/or Learning Disabilities and/or Autistic Spectrum Disorder SERVICES (irrespective of funding arrangements) including:
- NHS Mental Health Trusts
- NHS Learning Disabilities Trusts
- NHS Acute Trusts
- NHS Care Trusts
- Any qualified provider offering specialist secondary mental health, Learning Disability or Autistic Spectrum Disorder SERVICES
- Community SERVICES offering secondary care to children.
The Mental Health Services Data Set has historically been submitted using two submission windows, primary and refresh. This has changed to a multiple submission window model which gives submitters the opportunity to resubmit throughout the submission year. Guidance on the new submission model can be found on the NHS Digital website at: How to submit to the MHSDS.
