Correction to Table 1a
An issue has been identified and fixed with Table 1a of the Excel Data Tables. This issue had meant that Independent Sector Provider data for 2020-21 had duplicated with data for 2021-22. This meant that previously column AF in Table 1a was incorrect. An update has now been made and the tables reissued. NHS England apologises for any inconvenience caused.

Correction for Surrey and Sussex ICB populations , Table 8b and Length of Detention CSV file
Three corrections have been made to this publication:
1) The population figures for two Sub ICBs were incorrect. The two incorrect areas were NHS SURREY HEARTLANDS ICB - 92A and NHS SUSSEX ICB - 70F. Data for 70F previously had no population recorded whilst the data for 92A had been over reported. The associated rates for these Sub ICBs and ICBs have fixed and republished.
2) An issue was uncovered where the African and Caribbean ethnicities had been mixed up in Table 8b of the Excel file. This file has been fixed and replaced. The underlying data in the CSV was correct.
3) An issue with 'Length of Detention' CSV file uncovered where some of the England level data for section 'MHA and CTO' were suppressed. This file has been fixed and replaced.

Detentions
New detentions
In 2022-23 we report 51,312 new detentions, of which 34,982 took place at the point of admission to hospital. A further 12,792 occurred following admission. We also report 3,392 detentions following a place of safety order and 181 after the revocation of a CTO. Please see the "Are the MHSDS data complete?" section for guidance on interpreting data quality and completeness.
Proportion of detentions
A slightly higher proportion of detentions occurred on admission in NHS providers than independent providers 67.2 per cent compared to 66.4 per cent. For independent providers, 27.0 per cent of detentions occurred following admission compared to 24.8 per cent in NHS facilities.
Estimating the change in detentions
The headline detention figures for 2022-23 are down 3.8 per cent from last year. This does not represent the true change in detentions due to changes in data quality. MHSDS data quality (as the main data source) has improved and that from Acute providers making separate ECDS returns has increased. The ECDS is a relatively new dataset, therefore the number of submissions and data volumes are improving year on year. This year a number of new providers submitted detention data through ECDS which will affect the year on year change. To measure change more accurately, year on year differences in detentions are assessed on a subset of providers with stable data submission patterns. For further information please refer to the Background Data Quality Report.
In order to provide a like-for-like comparison to last year’s figures, we have limited our analysis to a smaller group of 24 providers (23 NHS and 1 independent). These providers all submitted data to KP90 in 2015-16. They all remained open to 2022-23, and submitted 12 months’ data about the Act to the MHSDS during each annual period. In addition our ongoing investigations did not reveal any significant data quality issues in their MHSDS data about the Act.
Using this methodology, our estimate for the true change in detentions from 2021-22 to 2022-23 is an decrease of 7.7 per cent.
The following measures are included in the comparison:
- Detentions on admission
- Detentions following admission
We have not included detentions following use of section 136 and revocation of community treatment orders as completeness for these measures are affected by different factors.
