Issue with legal status breakdowns in historical publications

Please note that an issue has been identified within the legal status breakdown within tables 2.3, 4.1 and 4.2. These breakdowns relate to whether the patient was detained under the Mental Health Act, Mental Capacity Act or other acts.

Impact

NHS England has completed an impact assessment which showed that previously the number of patients who were subject to the MHA was being overreported by 1 and 2% of total patients. In the most recent 12 months this was closer to 1% - the median across all time periods reported was 1.1% and 25 patients.

Most of these patients were detained under the Mental Capacity Act (MCA) and other acts but were reported as MHA Other.  Within the specific parts of the MHA, a small number of patients were reported under MHA Other but should have been reported under Part II, correcting the MHA Part II figures has largely not made a difference to the rounded figures. All figures for Part III with and without restrictions were reported correctly.

Current Publication

This issue has been resolved in time for the May-26 publication but impacts historical publications using data from the Assuring Transformation dataset.

Historical Publication

NHS England will not republish historical files with updated data but caution is advised in using these breakdowns and users should use the publications from the May-26 publication onwards for correct counts of patients detained under specific sections of the MHA.

NHS England apologises for any inconvenience caused.

Methodological Changes to the publication

Two changes have been made to the methodology for measures within the AT data tables, with effect from the
publication of April 2026 data.

  • Patient total length of stay will now be calculated by combining contiguous episodes of care into spells. 
    All values for hospital start date and earliest admission date in episodes within the spell will be considered
    to establish the original admission date.
  • Where patient records indicate that an episode of care ended on the last day of the month
    and a new one started the next day, but the data indicates that it was a continuous stay in hospital,
    the patient will now be counted as in hospital at the end of the month. 

These changes will mean a more accurate view of the number of patients in hospital, and the total length of stay.
Full details of the change are published here

New tables within Assuring Transformation data tables

NHS England have added 3 new sub-national tables to the AT data tables with effect from the April 2026 data.
These tables present data at Integrated Care Board (ICB), Region and England level:

 - number and rate of admissions (for under 18s and adults)
 - number and proportion of patients in hospital with the longest lengths of stay
 - number of patients, by age group and patient category, and inpatient rate per million population

Integrated Care Board (ICB) changes from 1 April 2026

From 1 April 2026, 6 new Integrated care boards (ICBs) were established and the boundary of an existing ICB was widened
through the abolition of 12 existing ICBs.
Data in the AT tables is presented for the new ICBs.  One existing ICB and Sub ICB Location (SICBL) (Frimley) was divided,
with parts of its geographical footprint forming part of 3 different ICBs. As the divided SICBL cannot be mapped forward,
the comparability of time series for these 3 ICBs is affected - these are noted in the data tables.

Further details of ICB changes are available at NHS England » Integrated care in your area

Summary

Latest monthly statistics on people with a learning disability and autistic people in inpatient services from the Assuring Transformation (AT) collection and Mental Health Services Data Set (MHSDS).

Data on inpatients with learning disabilities and/or autism are being collected both within the AT collection and MHSDS. There are differences in the inpatient figures between the AT and MHSDS data sets and work has been ongoing to better understand these. LDA data from MHSDS are experimental statistics, however, while impacts from the cyber incident are still present they will be considered to be management information.

From April 2024, LDA MHSDS data has been collected under MHSDS version 6.

Data in the tables are presented by the current organisational structures. Old organisational structures have been mapped to new structures in any time series.

Key Facts

There were 2,130 people with a learning disability and autistic people in inpatient services at the end of May 2026

1,030 (49%) of these have had a total length of stay* over 2 years

*Total length of stay is the time since the date of first admission to any hospital as part of this continuous period of inpatient care.
