Mental Health Services Data Set Overview

Introduction

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 PATIENTS who are in contact with Mental Health Services.

The Mental Health Services Data Set covers Mental Health Services located in England, or located outside England but treating PATIENTS commissioned by an English Clinical Commissioning Group (CCG), NHS England and NHS Improvement specialised commissioner or an NHS-led Provider Collaborative.

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.

Submission information

The Mental Health Services Data Set is submitted centrally via the Strategic Data Collection Service in the Cloud (SDCS Cloud) maintained by NHS Digital.

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.

Mandation

The Mandation column indicates the recommendation for the inclusion of data.

Note: items in the Mandation column which are shown with notation P have not been approved by the Data Alliance Partnership Board and are included to facilitate piloting and testing of future data requirements, prior to formal inclusion in later versions of the Mental Health Services Data Set. These items have been included in the data set layout in order to provide advance notice to data providers and system suppliers of the intention to require these items at a later date. Unless ORGANISATIONS are engaged in piloting activities relating to these items, they should NOT submit any data item marked P.
