This is a supplementary page relating to the 'Autism Waiting Times Statistics’ publication of January to December 2022 data. It contains national level estimates and Sub ICB data for data relating to August 2022 to December 2022.
From August 2022 data onwards, actual national level data has been omitted from the autism waiting times publication. This is due to the impact of the ongoing cyber incident which has meant that, for the affected months, national level data cannot be considered an accurate reflection of activity.
In order to assist users until the cyber incident and its effects are resolved, NHS Digital has produced national level estimates for the affected months, calculated through imputation and published as supplementary information.
Background
The recent cyber incident impacted the following Mental Health Service providers:
NNV - YOUR HEALTHCARE
NO6 - RETHINK MENTAL ILLNESS
NV2 - THE HUNTERCOMBE GROUP
R1A - WORCESTERSHIRE HEALTH AND CARE NHS TRUST
RNK - TAVISTOCK AND PORTMAN NHS FOUNDATION TRUST
RNU - OXFORD HEALTH NHS FOUNDATION TRUST
RQ3 - BIRMINGHAM WOMEN'S AND CHILDREN'S NHS FOUNDATION TRUST
RV5 - SOUTH LONDON AND MAUDSLEY NHS FOUND TRUST
RWV - DEVON PARTNERSHIP NHS TRUST
RXA - CHESHIRE & WIRRAL PARTNERSHIP NHS FOUNDATION TRUST
RY6 - LEEDS COMMUNITY HEALTHCARE NHS TRUST
RYG - COVENTRY & WARKS PARTNERSHIP NHS TRUST
TAF - CAMDEN & ISLINGTON NHS FOUNDATION TRUST
It has been necessary to impute the National Measures assuming these providers are not submitting data.
While NHS Digital work with providers to try and improve the data for those affected by the cyber incident, a set of data files presenting national level data using imputed values is being published to provide users with estimates of national activity.
The files below provide national level data and present the observed value from the providers known to not be impacted by the cyber incident, the factor applied for each measure and the imputed value.
For the measures which have been recalculated using the imputed values, the factor will be blank.
Methodology
In order to create estimates from the data submitted for Performance August 2022 onwards, data was run for the period August 2021 to July 2022 to create national totals for all providers and national totals excluding the 13 impacted providers listed above. From this, NHS Digital was able to calculate the average percentage difference across the 12 month period. We were then able to apply this factor to the current observed values from the data submitted to MHSDS (excluding the providers listed above). Where possible NHS Digital has tried to recalculate rates or proportions using the imputed value rather than estimating a new rate or proportion.
This methodology allows for the calculation of national totals which, for the most part, are in line with the actual published metrics between August 2021 and July 2022. Extreme caution should be used when interpreting these statistics however, and the following should be considered:
Data presented are estimates based on providers submitting data to MHSDS who are not impacted by the cyber incident. The trends and activity reported by these providers is for the most part reflective of the providers impacted by the cyber incident but given the lack of data, this is currently an assumption.
For volatile metrics or metrics which include smaller numbers, the accuracy of the estimates is reduced. Estimates for ASD14 (including a and b), ASD23 (including a and b) and ASD24 (including a and b) are as much as 30% different when compared with the actual published metric values. For this reason, these metrics have not been imputed.
Counts are also presented with both the minimum and maximum factors which were calculated from the data. This data is included to help users understand the possible range of values the imputed values could cover.
Sub ICB data has been separated from the main publication page as there are known data quality issues with specific ICB and Sub ICB locations due to the lack of data flowing into MHSDS due to the cyber incident.
It should be expected that ICBs and Sub ICB locations which these providers cover will report much lower values in the calculated metrics.
