This annual report relates to data extracted from Mental Health Minimum Data Set (MHMDS) for activity undertaken within the financial year 2012-13.
The publication for 2012-13 was produced from a single file compiled by the Health and Social Care Information Centre (HSCIC) from the quarterly submissions (2012-13 data). This uses a new, centrally derived, unique Spell ID to link patient spells across these quarters.
We have, for this publication, designed a process for compiling a cumulative annual file, which removes the duplication of episodic data that occurs across (and sometimes within) quarterly submissions. From April 2013, MHMDS (v 4.1) has been published monthly and this data will be linked using the unique Spell ID to create an annual file for this data for 2013-14 reporting.
Quarterly analyses and associated data quality measures for 2012/13 have already been released as quarterly publications and include different measures to this annual report.
In addition to the standard annual outputs, this year's report includes a special topic focusing on 'self-harm' which utilises the linkage work undertaken by the HSCIC between Hospital Episode Statistics (HES) and MHMDS. We know there is a lot of interest in this linked dataset and our special feature provides specific analysis of the underlying data.
