How do I submit data to the Mental Health Services Data Set?

Find out how to submit data to the Mental Health Services Data Set, including information for suppliers and providers, along with submission deadlines.

2018/19 data should still be submitted via the Bureau Service Portal using the MHSDS v3.0 Intermediate Database (IDB). March 2019 refresh data can be submitted between 2 May 2019 and 23 May 2019.


April 2019 data and all subsequent 2019/20 data should be uploaded via the new Strategic Data Collection Service (SDCS) cloud using the MHSDS v4.0 IDB. April 2019 primary data can be submitted between 2 May 2019 and 23 May 2019. April 2019 refresh data can be submitted between 1 June 2019 and 20 June 2019.

Who should submit data to the Mental Health Services Data Set (MHSDS)?

The MHSDS applies to all service providers and organisations that provide specialist secondary mental health, learning disabilities and autism spectrum disorder services.

How do I implement the data set?

The MHSDS defines an output standard; it does not represent a definitive list of data items and values which may need to be captured locally for care delivery, merely a subset of data requiring local extraction for central submission for analysis purposes. Service Providers have the flexibility to adopt any local data collection process or system which is able to collect and output the data as described in the data set specification. The type of service delivery locally will determine the data collected and so able to be submitted centrally. For example providers not delivering outpatient services will not be able to submit outpatient data.

The data set is not a patient care record but is based on clinical and operational information. Providers should therefore look to re-use their clinical and operational systems to extract MHSDS data.

Read more about the implementation of the data set in the Implementation Guidance.

What do service providers need to do?

Mental health, learning disabilities and autism spectrum disorder services that are either mandated, or opt, to flow data must be fully conformant with the standard. Submission of the data set is guided by the data set scope, which describes for instance the client age group, services received and funding streams which require submission. Providers must give full consideration to the scope of the data set to ensure complete representation of the services delivered to be included in the data set.

What do suppliers of IT systems need to do?

Suppliers of mental health, learning disability and autism spectrum disorder service IT systems should ensure that provider systems are able to capture and/or derive the data items defined in the MHSDS. Provider systems should be able to generate extracts which comply with MHSDS and BSP submission requirements.  

How do I register to submit data to the MHSDS?

Service providers must submit MHSDS data via the Strategic Data Collection Service (SDCS) using a registered account.

Read more about how to submit data via the SDCS in the Registration and User Guide.

Please note the following guidance which specifically focuses on the steps that must be in place in order for an organisation to be ready to submit the MHSDS to NHS Digital via the Strategic Data Collection Service (SDCS).
