HES-MHMDS Data Linkage Report, Summary Statistics - October 2013, Experimental statistics
This is the latest monthly (October 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 October 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.
There are approximately 1.44 million individuals who are recorded as being users of adult mental health services (within MHMDS) in the period April 2013 to October 2013.
Of these, approximately 1.37 million MH service users are aged 18 or over1 and can be linked to HES, of this subset in the period April 2013 to October 2013:
It is estimated that around 379,000 (or 28 per cent) had at least one inpatient episode of care
It is estimated that around 836,000 (or 61 per cent) had at least one outpatient appointment
It is estimated that around 445,000 (or 33 per cent) had at least one A&E attendance
It is estimated that around 983,000 (or 72 per cent) accessed at least one hospital service (inpatients episode of care, outpatients appointment or A&E attendance)
Comparing the frequency of access to hospital services (inpatient episodes of care, outpatient appointments or A&E attendances) between MH service users and non-MH service users:
Mental Health service users who accessed hospital services during April 2013 to October 2013 did so more frequently, approximately twice as much, as the corresponding Non-MH service user population.
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
