Notices of correction

We want to generate trust in what we release through a commitment to transparency. What we produce will meet consistent standards of behaviour that reflect the wider public good and be:

truthful
impartial
independent

It's possible that despite our quality control procedures, there may have been errors in methodology, underlying data or processes when producing our statistics.

Where an error is found, we'll assess the impact of this on the interpretation of the statistics. We'll determine an appropriate response to correct the error and alert you.

Major errors which would change the interpretation of data will be corrected and the publication updated. This is to show you the impact of this, with known users notified directly where possible.

Minor errors which do not change the interpretation of data will be corrected in subsequent publications, with supporting tables updated as soon as possible. In all cases, any unscheduled corrections will be communicated on this page. This is to ensure full transparency of our processes.

You can view each iteration of our publications and their associated correction notices on this page. All corrections will be made in line with our Revisions and Corrections Policy.

Medicines Used in Mental Health - England

2015/16 to 2021/22 Annual Summary Statistics

Date of Notice: 2 August 2022

It has been identified that data has been assigned to the incorrect IMD Decile in the statistical summary tables of the latest release. This is due to an ordering error in code used to produce these statistics.

This affects Table 8: Indices of Deprivation (IMD) in each of the statistical summary tables found in the resources list for this release.

Corrected tables have been produced assigning Total Identified Patients, Total Items, and Total Net Ingredient Cost (GBP) to the correct IMD Decile.

There is no change to the key findings of this release and the correct data was used in the statistical narrative.

The mislabelling of this field would contradict the conclusions that would previously have been drawn using data from the statistical summary tables.

We're sorry for any inconvenience this has caused.

2015/16 to 2019/20 Annual Summary Statistics

Date of Notice: 10 December 2020

It has been identified that a column, Identified Patient Flag, was omitted from the statistical summary tables of the latest release.

This affects Table 4 - STP in each of the statistical summary tables found in the resources list for this release.

The tables have been reproduced to include the omitted column.

There is no change to the key findings of this release. The omission of this field would not contradict the conclusions that would previously have been drawn from the data.

We're sorry for any inconvenience this has caused.

Prescription Cost Analysis – England

2019 Annual Summary Statistics

Date of Notice: 5 May 2020

It has been identified that a column, Standard Quantity Unit, was omitted from the presentation level tables of the latest release.

This affects Table 5 (Presentations) in the Prescription Cost Analysis 2019 – Statistical summary tables (Excel: 3.8MB), and the historical presentation level tables which are also added as yearly CSVs to our Open Data Portal.

This omission was caused by an oversight on our part during the transition of this publication from NHS Digital. The standard quantity unit is a field that is no longer available to us after our move to a single source of information for drugs reporting. This was discussed in the Background Information and Methodology note that accompanies this release. NHS Digital communicated this in their 2018 release but were able to carry out an exercise to make this column available.

We appreciate that we have not clearly communicated the removal of this field in our publication as a pre-announced change to the 2019 release when we should have done, along with the reasoning behind this and any impacts on the statistics.

Unfortunately, we are unable to amend the released data to include this field, as it is no longer held as an attribute within our reporting systems. A potential replacement for this field has been identified that is held within our systems. However, we cannot re-release this year’s publication with it included due to issues that it would create with disaggregation of historical data. It's anticipated that this field will be included in the PCA – England 2020 release.

There is no change to the key findings of this release, nor would the omission of this field contradict the conclusions that would previously have been drawn from the data.

We’re sorry for any inconvenience this has caused.
