Summary
This is the latest monthly (January 2014) statistical publication in relation to the linked HES (Hospital Episode Statistics) and MHMDS (Mental Health Minimum Data Set) data.
The two data sets have been linked using specific patient identifiers collected in HES and MHMDS. The linkage allows the data sets to be linked in this manner from 2006-07; however, this report focuses on patients who were present in the two data sets in the period April 2013 to January 2014 only.
The bridging file used for this publication was also released on 16 May 2014; it utilises the latest published Provisional (Monthly) HES data and year-to-date MHMDS data relating to the period April 2013 to January 2014.
The HES-MHMDS linkage provides the ability to undertake national (within England) analysis along acute patient pathways for mental health service users' interactions with acute secondary care.
Highlights
There are approximately 1.63 million individuals who are recorded as being users of adult mental health services (within MHMDS) during April 2013 to January 2014.
Of these, approximately 1.55 million MH service users are aged 18 or over¹ and can be linked to HES, of this subset in April 2013 to January 2014:
it is estimated that around 535,000 (or 35 per cent) had at least one inpatient episode of care
it is estimated that around 1,030,000 (or 67 per cent) had at least one outpatient appointment
it is estimated that around 616,000 (or 40 per cent) had at least one A&E attendance
it is estimated that around 1,201,000 (or 78 per cent) accessed at least one hospital service (inpatient episodes 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 January 2014 did so more frequently, approximately 1.7 times as often, as the corresponding Non-MH service user population.
