Mental Health Inpatient Census 2023 - Parts 1 and 2
Results of the seventh Mental Health and Learning Disability Inpatient Census and Outwith NHS Scotland Placements Census, 2023.
Methodology and further information
The Inpatient Census was carried out on 12th April 2023 by the Scottish Government and all NHS Boards. This was the seventh time the Census has been undertaken. The Census covered three parts:
- Part 1: Every patient occupying a psychiatric, addiction, or learning disability inpatient bed in an NHS Scotland facility on the Census date.
- Part 2: Every mental health, addiction, or learning disability patient whose care is funded by NHS Scotland but is being treated in a facility outside outwith NHS Scotland.
- Part 3: Every patient who was in receipt of Hospital Based Complex Clinical Care (HBCCC) in general acute inpatient beds on the Census date.
This report contains analysis from Parts 1 and 2 of the Census. A separate report covers all Hospital Based Complex Clinical Care and Long-Stay patients from Parts 1, 2, and 3.
All 12 NHS Scotland territorial boards with psychiatric, addiction, or learning disability inpatient beds provided a return. The State Hospital (Special NHS Board) also provided a return.
Data completeness for individual Census questions varied. Any missing data is footnoted in corresponding tables or displayed in the chart. Although most health boards had some missing data, for 143 of their patients (47%) NHS Tayside could only provide minimal data, including admission dates, age and diagnoses.
All NHS Scotland territorial boards with mental health, addiction, or learning disability patients treated outwith NHS Scotland provided a return.
Data collection
The Scottish Government’s Digital Aquisition Services provide data collection and validation support for a number of statistical returns. Digital Acquisition Services provided secure data collection software (procxed.net) and first stage data validation checks. Further information about the data collection software can be found in the Data Privacy Impact Assessment which can be obtained on request from MHIC@gov.scot
Health and Social Care Analysis division undertook secondary validation checks.
The data collection, analysis and report has been overseen and produced by statisticians. All statisticians in the Scottish Government are part of the Government Statistical Service (GSS) which comprises the statistics divisions of all major departments in the UK Government, and the devolved Governments of Scotland, Wales and Northern Ireland plus the Office for National Statistics, which has a coordinating role for the GSS.
Revisions to 2022 report and archiving of pre-2022 publications.
As a result of a 2024 project to improve the internal coding used in the analysis of the Census, some errors were discovered in the process used to collate the data needed to build the Census dataset.
The errors meant that a small amount of data relating to the number of inpatient beds was missing across the years 2014 (Forth Valley), 2016 (Fife and Lothian), 2017 (Grampian and Lothian), 2019 (Tayside) and 2022 (Lanarkshire and Lothian). The Census in 2018 was unaffected. The majority of health boards (8) were unaffected by any errors across the timespan of the Census.
The missing number of beds and the health boards affected across the years are described and tabulated in the tables below:

* data not published for census years 2014 and 2016.
The key messages are:
- The missing data for beds is not impactful at a Scotland level and does not affect all health boards.
- None of the key messages, trends or conclusions at a national level from previous publications are affected.
- Some health board-level data and tables will be affected in previous publications, although broadly, the impact is limited.
- Whilst the amount of missing data is small, it permeates through a range of tables and commentary which makes a complete overhaul of all previous years publications prohibitively, and disproportionately, costly in terms of the analyst time required to re-run and republish all of the data.
The actions we have taken are:
- Changes to the data collection procedures and new validation checks have been implemented to prevent a re-occurrence in the future.
- The publication and data for 2022 has been revised and re-published alongside the latest 2023 publication.
- The latest publication (2023) uses all of the revised data from 2022.
- Tables and graphs in the revised 2022 and latest 2023 publication have been clearly marked for users to indicate that direct comparisons (for some health boards) are not possible across the entire time series.
- Publications prior to 2022 have not been revised and have instead been archived in a separate part of the HSC website with clear messages for users about the missing data.
- The decision to archive pre-2022 publications was taken after a consideration of the resource required to rebuild and re-run all of the analysis and republish all of the time series from 2014 onwards. The conclusion was that this work would have incurred a disproportionate cost, given the relatively small impact of the missing data. The best solution was therefore to archive the data and publications, still making them available to users but with clear signposting about the approximate nature of the results.
Implementation of sex and transgender questions
In 2023 the questions used to collect data in this area were aligned with the Scottish Government, Office of the Chief Statistician’s guidance on sex, gender identity and trans status:
This improved the language, design and consistency of the questions being used and has enabled people to be more appropriately represented in the survey.
The change to reporting of sex instead of gender and the introduction of extra questions here also brings the Census questions into alignment with other Health and Social Care surveys such as the Scottish Health Survey, and the National Records of Scotland population census.
The change in the questions asked in the Mental Health Impatient Census is described below:
Prior to 2023 the following question was asked:
Q - Gender of patient:
- Male
- Female
- Other
- [for coding only] Not known
From 2023 onwards, the following questions are now asked:
Q - Sex of patient:
- Female
- Male
- Prefer not to say
- [for coding only] Not known
Q - Does the patient consider themselves to be trans, or have a trans history?
- Yes
- No
- Prefer not to say
- Not known
Q - If the patient would like to, how would they describe their trans status (for example, non-binary, trans man, trans woman)?
- Answer can be supplied as free text response.
This means that from 2023 onwards data on sex that is reported in the Census is not directly comparable with data collected on gender for prior years. Notes have been added to the relevant sections of the publication to make this clear.
The Census is one of the data collections that is part of the Equalities Data Improvement Programme (EDIP). The EDIP was a commitment to expand and make improvements to protected characteristics data. This was part of the wider Equality Evidence Strategy, published in March 2023. More details on this are provided here:
Scotland’s Equality Evidence Strategy 2023-2025 - gov.scot (www.gov.scot)
Plans for future Censuses
In 2025, as part of the EDIP commitments, we plan to expand the range of protected characteristics data collected.
It is also our intention in 2025 to run a consultation with the users of the CEnsusto find out what content is most useful for users and to gather views on any changes users would like to see in the data collection and publication. We will post more information on our Census website as our planning for this develops.
Data confidentiality
A Data Protection Impact Assessment was undertaken prior to the Census which outlines how patient confidentiality is maintained. The Data Protection Impact Assessment can be obtained on request from MHIC@gov.scot
In addition, statistical disclosure control has been applied to the analysis. Statistical Disclosure Control (SDC) covers a range of ways of changing data which are used to control the risk of an intruder finding out confidential information about a person or unit (such as a household or business). This publication has used the following methods where there are under 5 patients in a particular category:
- Suppression of possibly disclosive cells (e.g. where the value is small) which means that the value for that cell in the table is not given and secondary suppression of cells which means at least one other value in the row or column is also not given to ensure that disclosive cells cannot be deduced through subtraction
- Table redesign and recoding, where cells are grouped together to protect small value cells.
Further information about Statistical Disclosure Control is available here:
Statistical disclosure control - Office for National Statistics (ons.gov.uk)

Autism
For the purpose of this report, the autism cohort is defined by the patient meeting at least one of the following criteria:
Diagnosis of Autism |
ICD-10 Code F84.0 or F84.1 |
NHS Boards answered Yes to the following health condition question: Autistic Spectrum Disorder |
1 - Yes 0 - No |
Alcohol misuse cohort
For the purpose of this report, the alcohol misuse cohort is defined by the patient meeting at least one of the following criteria:
Diagnosis of Alcohol Misuse |
ICD-10 Code F10 |
NHS Boards answered either 1 or 3 to the following question:
Was there a history of alcohol dependence or substance abuse in the four weeks prior to admission to hospital/care home? |
1 - Yes – alcohol dependence or harmful use of alcohol only 2 - Yes – substance abuse (excluding alcohol) 3 - Yes – both alcohol dependence and other substance abuse |
The above definition is applicable for patients treated within NHS Scotland facilities only.
Drugs misuse cohort
For the purpose of this report, the drug misuse cohort is defined by the patient meeting at least one of the following criteria:
Diagnosis of Drug Misuse |
ICD-10 Code F11 – F19 |
NHS Boards answered either ‘2’ or ‘3’ to the following question:
Was there a history of alcohol dependence or substance abuse in the four weeks prior to admission to hospital/care home?
|
1 - Yes – alcohol dependence or harmful use of alcohol only 2 - Yes – substance abuse (excluding alcohol) 3 - Yes – both alcohol dependence and other substance abuse |
The above definition is applicable for patients treated within NHS Scotland facilities only.
A question on non-prescribed drug use during hospital stay in the 2016 Census that contributed to the drug misuse count was not asked in 2017 so that questions on physical health checks to be included. However, only a small number of patients using non-prescribed drugs during hospital stay had no prior substance use in the 4 weeks before admission. Therefore, its exclusion had minimal impact on totals.
Forensic patients
Forensic patients were identified if NHS Boards indicated ‘yes’ to the following Census question: is the patient being managed primarily by forensic services?
Access to the data for further research
To enable further research and statistical analysis, extracts of the Inpatient Census data may be made available for approved researchers.
Academic researchers must initially apply to the ‘Statistics Public Benefit and Privacy Panel’ or the ‘Public Benefit and Privacy Panel for Health and Social Care' to gain access to the Inpatient Census data. If the ‘Statistics Public Benefit and Privacy Panel’ or the ‘Public Benefit and Privacy Panel for Health and Social Care’ approve an application then a copy of the original application form and a copy of the approval letter should be emailed to the following address MHIC@gov.scot for approval by the Scottish Government (Health & Social Care Analysis Division and the Principal Medical Officer for Mental Health).
NHS Boards will have a version of the Inpatient Census dataset which contains information about patients for whom they are responsible for providing treatment, or are responsible for funding. NHS boards will have their own arrangements in place for researchers to access health data. All Boards have a Caldicott Guardian who is responsible for assuring confidentiality and enabling appropriate data sharing, and a director responsible for research and development.
