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 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. MHSDS brings together key information from Adult and Children's mental health, learning disabilities or autism spectrum disorder, CYP-IAPT and early intervention care pathway that has been captured on clinical systems as part of patient care.
