This is the latest monthly (July 2013) statistical publication in relation to the linked HES (Hospital Episode Statistics) and MHMDS (Mental Health Minimum Dataset) data.

The two data sets have been linked using specific patient identifiers collected in HES and MHMDS. The linkage allows the datasets to be linked in this manner from 2006/07; however this report focuses on patients who were present in the two datasets in period April 2013 to July 2013 only.

The HES-MHMDS linkage provides the ability to undertake national (within England) analysis along acute patient pathways for mental health service users, thereby enabling a much deeper understanding of MH (mental health) service users' interactions with acute secondary care.

Key facts

There are just over 1.2 million individuals who are recorded as being users of adult mental health services (within MHMDS) in April 2013 to July 2013.

Of these, over 1.1 million MH service users are aged 18 or over1 and can be linked to HES, of this subset in April 2013 to July 2013:

  • It is estimated that around 220,000 (or 19 per cent) had at least one inpatient episode of care
  • It is estimated that around 620,000 (or 53 per cent) had at least one outpatient appointment
  • It is estimated that around 260,000 (or 23 per cent) had at least one A&E attendance
  • It is estimated that around 730,000 (or 63 per cent) accessed at least one hospital service (inpatients episode of care, outpatients appointment or A&E attendance)


1. While MHMDS can legitimately contain records for under 18’s its primary focus is adults accessing the services and therefore is not fully representative of the under 18’s age group.
