Access data from the Mental Health Services Data Set

Find provider and commissioner extracts, and publications, from the Mental Health Services Data Set.

Page contents

Publications

NHS England produces statistical releases that make available the Mental Health Services Data Set (MHSDS) data. These releases are publicly available and will be of interest to a range of users including service providers, commissioners, patients, researchers, agencies and the wider public.

Provider and commissioner extracts

Providers and commissioners of adult mental health, children and young people's specialist learning disabilities or autism spectrum disorder, CYP-IAPT and early intervention services can retrieve processed Mental Health Services Data Set (MHSDS) extracts covering their own services and the patients for whom they are responsible from the Bureau Service Portal.

Providers

Provider extracts contain data for their own services and patients.

Commissioners

Commissioner extracts will be filtered by organisation code (Code of Commissioner) and commissioners can only receive records where their NHS organisation code matches that supplied by the provider for the patient. The structure, format and content of this extract are similar to the provider's final extract, but the extract does not include patient identifiable data items.

Commissioner access is subject to approval by the Advisory Group for Data (AGD). Commissioners should initially contact their commissioning support unit or Data Services for Commissioners Regional Office to obtain data, as access will no longer be granted to individual clinical commissioning groups on the Bureau Service Portal.

Specifications for the Provider and Commissioner Extracts are contained in the Technical Output Specification and describe exactly what data are contained in the extracts.

How do we use and protect patient identifiable data?

We take the importance of information governance very seriously. We have controls and procedures in place to make sure we demonstrate the highest standard of stewardship and governance of the information we handle, including the MHSDS.

We conform to the standards of the Governance Committee (formerly the National Information Governance Board), the national body that protects the interests of patients in how their data are used, shared and stored in the NHS and adult social care.

Patient identifiable data is collected extensively across all areas of health for both clinical and management purposes. The Governance Committee's Care Record Guarantee sets out the "commitment that NHS organisations and those providing care on behalf of the NHS will use records in ways that respect patient rights and promote your health and well-being." This principle is applied across all national data collections including all of our mental health information. 

We make sure individual patients cannot be identified by creating a pseudonymised patient identifier which is used in national aggregate reporting.

We make sure all data is kept secure whilst it is being submitted. The Bureau Service Web Portal which is used to submit the data has secure 'https' technology to encrypt data transmitted across the N3 network. The portal has successfully passed extensive testing designed to identify any security issues.

The data we collect will help us to understand how services operate, the treatments they provide and the outcomes they achieve - and helps improve the way they are delivered.
