Error in adult inpatient rates in Assuring Transformation (AT) Table 5.2

We have identified an error affecting the adult inpatient rates presented in Assuring Transformation (AT) Table 5.2.  The error affects each AT reporting period from October 2023 to June 2025 inclusive.

The error arose due to the rate calculation having been performed using ONS mid-year population estimates from the year 2020 rather than 2017.  The adult inpatient numbers in this table are unaffected by the error.

The affected rates data has now been redacted from Table 5.2 in each of the affected publications. 

Corrected rates for March 2024 and March 2025, the ‘end-of-year’ months, have been published on Supplementary Information here.

NHS England apologises for any inconvenience caused.

The Master Provider and Site List in Assuring Transformation

From October 2023 a Master Provider and Site List (MPSL) has been developed for mental health inpatient services for people with a learning disability and autistic people. This MPSL has been incorporated into Assuring Transformation on the Clinical Audit Platform (CAP) so that data submitters can pick from a much smaller list of inpatient services for people with a learning disability and autistic people. 

For more information on the MPSL please click the below link:

Changing the submission windows for the Mental Health Services Data

To provide more timely statistics in the Mental Health Services Monthly Statistics and Learning Disability Services publication series, from October 2023 activity, revised submission windows have been introduced to support a move to reporting performance data in the month following activity.  Editions of the series from this one onwards are affected by this change, and each publication page will contain data relating to one month only.
