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.

For more information on the submission windows for MHSDS and how they are changing please see the below link:

Changing the submission windows for the Mental Health Services Data from October 2023 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.

The September 2023 performance publication contains all data relating to the reporting period in it.

The October 2023 performance publication does likewise with the exception of restraints data.  This is because the restraints data is being published in the second month following the activity.  Providers have indicated that there is often some delay until the restraints data is available for them to submit.  As a result, the timeliness with which NHS England receives restraints does not currently support 'first cut' reporting, although it may do in the future should timeliness improve.

The October 2023 publication will have ‘second cut’ restraints data added to it on 18th January 2024.  We will also publish November 2023 data on this day, again omitting the ‘first cut’ restraints data (assuming timeliness is still an issue), ensuring it is added in February 2024 once 'second cut' restraints data is available.


MHSDS LDA provisional and final data

Published data which are labelled as ‘performance’ are produced from primary monthly submissions, (i.e. the first submission of each month’s data). Performance statistics are indicative and subject to change.

Providers are able to make an optional 'refresh' submission at the time of the next month's primary submission. Statistics which have been published under the label ‘final’ are a combination of both the primary and refresh submissions. Where a refresh submission is made, the primary submission is not used. If a refresh submission is not made then the primary submission is used. This ensures the most complete and latest picture for the MHSDS is made available. Once final statistics are published then any provisional statistics for the same period should no longer be used.


Extracting LDA data from MHSDS

For this publication people are identified in MHSDS as having learning disabilities and/or autistic spectrum disorder (LDA) characteristics within their submitted data for the reporting period (Full details of the method used to identify people with learning disabilities and/or autism are provided in the metadata file). LDA measures are presented for referrals and inpatient activity, in data tables and a CSV file.

These measures show the volumes of patients accessing services throughout the month. This is summarised into five types of measurements:

  1. Open referrals/inpatients accessing services at the start of the reporting period
  2. New referrals/ admissions during the month
  3. Referrals closing/ discharges during the month
  4. Referrals opening and closing/ inpatients admitted and discharged within the month
  5. Open referrals/ inpatients accessing services at the end of the reporting period

The inpatient data has been created to replicate the measures currently available in the Assuring Transformation publication. It includes LDA patients with ‘a bed’ normally designated for the treatment or care of people with a learning disability or those with ‘a bed’ designated for mental illness treatment or care who have been diagnosed or are understood to have a learning disability and/or autistic spectrum disorder.

We would welcome feedback on both the methodology we have used to identify the cohort of patients, and the reported measures. Please send any comments to [email protected]


Interpreting inpatient statistics

A group of measures about hospital spells and ward stays open at the end of the month can be used to provide a detailed picture of inpatient caseload at National, Provider and CCG of registration or residence level. Each measure has a unique identifier (referenced in the metadata file), to ensure that users know what is represented by each measure.

This national picture is incomplete without full submissions from all providers of inpatient services and gaps in the provision of information from independent sector providers will also affect the figures at subnational level to varying degrees. See the data quality section of this report for more details. These are experimental statistics and should be used with caution, using all the other available information about data quality to aid interpretation.


Statistical disclosure control

To prevent the release of disclosive information, for the majority of statistics within this publication any numbers less than five (including zero) are replaced by a “*” symbol. Please note for tables 15-18 of the data tables, this also denotes where a submission has been made but data in the relevant table has not been provided. All other numbers are rounded to the nearest five. Calculated values in the data files are based on unrounded numbers but rounded to the nearest whole percent to prevent backward calculation. Where a value is suppressed, the corresponding percentage is also suppressed. This approach prevents identification of a person through cross referencing different publications.

In line with the NHS Anonymisation Standard, since the total population of inpatients identified as having a learning disability and/or autism is less than 10,000, this disclosure control has been applied to national figures as well as sub-national figures.
