The Canonical Data Model (CDM) aims to standardise data structures across NHS England, facilitating data integration and interoperability.

The Canonical Data Model (CDM) aims to standardise data structures across NHS England, facilitating data integration and interoperability.
It is being developed incrementally and based on real-world use cases, and will be refined and approved through specific domains and topics. This model has been shaped by input from expert reference groups and subject matter experts and is designed to enhance the flow of data from source systems, leading to improved operational and analytical insights.
About the CDM
The model incorporates several key features and design principles to achieve its aims, ensuring data is robust, interoperable, and consistently understood: 
<ul>
<li>domain based development</li>
<li>subject of care centric</li>
<li>controlled vocabularies</li>
<li>metadata and CDM dictionary</li>
<li>technology agnostic</li>
<li>normalised structure</li>
<li>consolidates data standards</li>
<li>alignment with key standards</li>
<li>linked to NHS master and reference data</li>
</ul>
Layers of CDM
The CDM is structured in distinct layers, each building upon the last to ensure a model that is comprehensive and can be implemented.
<ul>
<li>NHS conceptual data model</li>
<li>This layer provides a high-level, technology-agnostic blueprint of fundamental healthcare concepts.</li>
</ul>
NHS logical data model (Canonical Data Model)
<ul>
<li>NHS conceptual data model</li>
<li>This technology-neutral layer defines the detailed structure and relationships of key data entities. This model represents the merger of the Federated Data Platform (FDP) and NHS logical models.</li>
</ul>
Physical data models
<ul>
<li>NHS conceptual data model</li>
<li>These models represent the actual physical implementation of the CDM, often taking the form of specific data products. 
</li>
</ul>

Nursing Care Needs Standard: Survey Report

Standardise/reduce unwarranted variation in the documentation of a nursing assessment in hospital, community, and nursing homes and share this information across health and care.

The standard aims to make a nursing assessment accessible at the point of care, should the persons move between places of care.
About this standard
The Nursing Care Needs Standard aims to improve the quality and safety of care in key nurse-led areas, including care planning. It reflects best practice and standardises documentation across different nursing settings, to free nurses and give them more time to care. For example, it standardises information that a nurse in a care home or community setting can access and share in the same way as a mental health or hospital nurse, with a focus on the person’s overall wellbeing.
People tell us that nursing care documentation is an important source of information about their health and care needs, their strengths, and the goals they want to achieve. It describes their quality of life and how this can be improved given their health and care circumstances and underlying conditions. This standard will enable more personalised care provision and enable better self-care.
A standard that allows the exchange of information between IT systems will also enable sharing of standardised information between nurses and other health and social care professionals in the persons’ circle of care for continuity and more timely care delivery. 
Scope
The standard is focused on eating and drinking, mobility, elimination (toileting and continence), personal hygiene and dressing, skin, and medication self-management.
The care settings in scope are:
<ul>
<li>Hospital</li>
<li>Community</li>
<li>Nursing home</li>
</ul>
Out of scope
<ul>
<li>Mandating which specific risk assessment tool should be used for an assessment.</li>
<li>Nurse treatment plans used by Clinical Nurse Specialists (CNS) and Advanced Nurse Practitioners (ANP) and in non-inpatient care settings.</li>
</ul>
The following clinical specialities and their patients’ needs have not been considered when developing this standard:
<ul>
<li>Midwifery</li>
<li>Neonatal care</li>
<li>Mental health nursing</li>
</ul>
(However, mental health settings may also need to assess functional needs – therefore, this standard should be used where relevant).

This standard is owned by NHS England and is made available for reuse or amendment under the Open Government Licence v3.0 (OGL 3.0).

Proposal for a new information standard to define the patient record requirements for shared decision making which will also define sharing mechanisms.

Shared decision making is a collaborative process where clinicians and individuals consider treatment options based on evidence about their potential benefits and harms, to enable the person to decide the best course for themselves. The conversation and decision made should be informed by what matters to the person, their goals, values, hopes, ideas, concerns and expectations.
When people are listened to, given the information they need and the time and support to make informed decisions about their care and treatment, they have the potential for better outcomes and experiences of care.
About this standard
The information standard on shared decision making provides a framework for clinicians to record the decision-making process between themselves and their patients. The standard also allows the shared decision information to be shared between professionals and their different record systems. The standard has been developed based on the <a href="https://www.gmc-uk.org/professional-standards/the-professional-standards/decision-making-and-consent">GMC guidance</a> on shared decision-making and consent and the <a href="https://www.nice.org.uk/about/what-we-do/our-programmes/nice-guidance/nice-guidelines/shared-decision-making">NICE guidelines.</a>
Scope
<ul>
<li>The standard was developed with UK wide consultation and engagement to meet the needs of all four UK nations.</li>
<li>The standard is intended for all areas of healthcare except for the noted exclusions</li>
<li>The standard covers all ages including children</li>
</ul>
The following 8 different scenarios were used to help develop and test the standard;
<ul>
<li>Elective surgery</li>
<li>Multiple long-term conditions </li>
<li>Mental Health </li>
<li>Genetic conditions </li>
<li>Polypharmacy </li>
<li>Orthopaedics </li>
<li>Gynaecology </li>
<li>Children and dentistry </li>
</ul>
Not in scope:
<ul>
<li>Maternity – The standard may work for maternity, but it is believed that this complex area justifies specific additional work and potentially an extended standard.</li>
<li>Social Care – The Shared Decision Making Standard is defined for clinical uses and the consultation was targeted at healthcare professionals not social care professionals. However the standard’s principles may work in social care and in the future the standard could potentially be adapted for use in social care.</li>
</ul>

## Data Coordination Board

Acting under delegated authority from the Secretary of State for Health, the Data Coordination Board has approved a change to an existing information standard for publication under section 250 of the Health and Social Care Act 2012.

>You must comply with this change by the full conformance date specified below.

## Standard details

DCB unique identifier: DCB1605 Amd 27/2017

Name: Accessible Information, version 1.1

Approval date: 3 August 2017

Publication date: 10 August 2017

## Standard definition

This information standard aims to make sure that people who have a disability, impairment or sensory loss get appropriate information and communication support from NHS and adult social care services.

 It requires all applicable organisations to identify, record, flag, share and meet the information and communication support needs of patients, service users, carers and parents with a disability, impairment or sensory loss.

Successful implementation will lead to improved outcomes and experiences, and the provision of safer and more personalised care and services to those individuals who come within the scope of the standard.

## About this change

The standard has been updated following a post implementation review undertaken in early 2017. Changes to the standard include:
* Updates to the meaning of certain terms used, including changes to the definitions for ‘parent’ and ‘highly visible’. 
* Amendments relating to mental health service users and the Mental Capacity Act 2005, to improve clarity, especially regarding support for people who may lack capacity.
* Inclusion of advice regarding support for individuals with a learning difficulty.
* Updates to reflect the current position regarding the inclusion and transfer of data recorded using existing systems.

The revised Implementation Guidance reflects these updates and also includes additional guidance on sharing of information (including consent), use of email / text message to communicate with patients / service users, parental responsibility, and to address some other specific queries that have been raised about interpretation. There are no substantive amendments to the Requirements of the Standard and no substantive changes to the overall scope.

Scope (Health and Health Services: NHS Services, Adult Social Care

Applies to: This standard applies to – and therefore must be implemented and adhered to by – ALL providers of publicly-funded NHS, public health and adult social care services.

Effective implementation will require such organisations to make changes to policy, procedure, human behaviour and, where applicable, electronic systems

Impacts Upon: Commissioners must ensure that their commissioning and procurement arrangements with providers of health and / or adult social care reflect, enable and support implementation and compliance with this standard. They must also seek assurance from providers of their compliance with this standard.

Implementation of this standard impacts all suppliers providing systems to the above providers; suppliers should work with their customers to determine appropriate use

Legal authority This information standard is published under section 250 of the Health and Social Care Act 2012.

It supports compliance with obligations under the Equality Act 2010.

## How accessible this website is
We know from several accessibility reports that parts of this website are not fully accessible.

### Usability issues
We have identified some issues that, although do not fail to meet Web Content Accessibility Guidelines (WCAG) 2.1, may prove challenging for users of the website. These include:
* some heading levels in the homepage increase by more than one level at a time
* some additional features within the filter section of the Current standards page may be beneficial for some blind users, such as the option to reset the filter options
* the details component used in standard listing pages is problematic for VoiceOver users
* the feedback link below the main menu does not include the destination as part of the hypertext
* when Window’s default colour inversion is used the search input is difficult to decipher for users with low vision
* nested lists in some of our content pages can make reading slow and difficult to some screen readers
* links to websites or software that we do not own or manage and so cannot guarantee their accessibility

We are actively working to address these issues as part of an ongoing programme to improve the accessibility of this website.

### Other websites that the directory signposts to

Your privacy is important to us. This privacy policy covers what we collect and how we use, share and store your information.

This page tells you:

* about the information we may collect
* how we keep your data secure
* who we share your data with
* about your rights to see or change information we hold about you

## Information we may collect

You can leave feedback on some pages of the website or on a user survey. You can choose to share your email address if you want a reply by emailing the team directly on [england.interop.standards@nhs.net](mailto:england.interop.standards@nhs.net). Otherwise, we collect and store feedback anonymously.

### How we use cookies

Our website uses cookies. These are small files saved on your phone, tablet or computer when you visit a website. They store information about how you use the website, such as the pages you visit.

The law says that we can store cookies on your device if they are strictly necessary to make our website work. We need your permission for all other types of cookies before we can use them on your device.

We like to use analytics cookies that measure how you use our website and help us improve our service for future users but we only use these cookies if you say it's OK.

[Read our cookie policy](/cookie-policy) to find out more about the cookies we use and tell us if we can put analytics cookies on your device.

We sometimes use tools on other organisations' websites to collect data or to ask for feedback. These tools set their own cookies.

#### How we collect and store your data

If you interact with us on social media, we may receive some personally identifiable data about you, which is supplied by the channel you are using (for example, Twitter or Linkedin). This may include:

* your name
* social media handles (such as Twitter account name)
* location history (where you are contacting us from)
* images (such as your profile picture)

We will process and store your data in accordance with the terms and conditions and privacy policy of the platform in question. You should be aware that your use of these platforms is governed by the terms and conditions agreed between you and the platform, rather than with us.

We will not remove, duplicate or transfer your personal data from or between any of the social platforms that we use, except for when you give us explicit permission to do so or when we believe that we need to in order to respond to an urgent risk to health.

You should be aware that social networks may control some of the data associated with interactions between you (the user) and us (NHS Standards Directory) on their platforms. For example, we will be able to delete our own records of a private message conversation if you ask us to do so, but social networks may store a copy of this conversation that we are unable to access.

We recommend using the privacy tools built into the social networks in question to make sure you are able to exercise your rights appropriately.

#### Understanding how social networks use your data

Social networks use information about your online activity to build a profile of you. This data is then used (anonymously) to send you targeted adverts across various digital platforms.

You should be aware that interacting with accounts such as ours may help build the profile of you that social networks maintain, and that could potentially result in you receiving adverts about related issues.

This process of collecting data for advertising purposes is not controlled by the NHS Standards Directory, and we do not have access to the profiling data stored by social networks about you.


## Keeping your personal data secure

We convert your data into secure code (encrypt it) and store it on secure servers in England. A partner organisation is providing hosting services but has no say in how the information is used. There are no legal ways for their employees to see the data. Only approved people in the NHS Standards Directory team can see it.

If you shared your email with us as part of a survey, we will delete it after 2 years. At that point no one can identify you in the survey data.


## Data sharing

NHS England may share anonymous information on how the service is used internally.

### Legal powers

When you give us personal information, we may pass it on if the law says we must.

If you make a claim against us, we and other third parties such as our solicitors may need to look at this information.

We will not share your personal information with anyone else without your permission for any other reason.


## Your rights

You can:


* find out what information we hold about you, ask us to correct it if it's wrong, or delete it by emailing [england.interop.standards@nhs.net](mailto:england.interop.standards@nhs.net). 
* contact the [Information Commissioner's Office](https://ico.org.uk/), Wycliffe House Water Lane, Wilmslow SK9 5AF if you want to make a complaint about how we have managed your data

## What this service does

The directory is a source of recognised standards used by technologies in health and adult social care to exchange data in England. 

It is a signposting service only. It doesn’t include the full documentation for each standard. This can be found on the standard owner’s website.

This service is currently in development and is being tested and improved based on feedback. To report a problem or make a suggestion, email <a href="mailto:england.interop.standards@nhs.net">england.interop.standards@nhs.net</a>.

To learn more about why this service was needed and the future plans for it there is a <a href="https://digital.nhs.uk/blog/tech-talk/2022/discovering-data-standards-together">2022 blog written by the Product Manager</a> of the NHS Standards Directory.

[Find out more about standards](/about-standards).

## Who this service is for

This service is for anyone building or buying digital technologies for the NHS or local authority-funded adult social care services in England. 

This includes IT suppliers, healthcare providers and technology buyers such as procurement teams and framework operators.

## What standards are included

The directory lists all standards that are mandated at a national level as well as some standards that are not mandatory but are widely in use in England. These include: 

* all approved national [information standards](https://digital.nhs.uk/data-and-information/information-standards/information-standards-and-data-collections-including-extractions/publications-and-notifications/standards-and-collections#approved-standards-and-collections). These are assured by the [Data Alliance Partnership Board](https://digital.nhs.uk/data-and-information/information-standards/information-standards-and-data-collections-including-extractions/data-alliance-partnership-board) and issued with an Information Standard Notice, which means they are mandatory.
* APIs published in [NHS Digital's API Catalogue](https://digital.nhs.uk/developer/api-catalogue)
* record standards published by the [Professional Record Standards Body](https://theprsb.org/)

It also includes draft APIs and draft standards that are in the process of being assured at the national level.

More standards are likely to be added to the directory in the future. You can find [data collections and extractions on NHS Digital’s website](https://digital.nhs.uk/data-and-information/information-standards/information-standards-and-data-collections-including-extractions/publications-and-notifications/standards-and-collections#approved-standards-and-collections). 

When writing information around standards there is an aim to provide clear, accessible and useful metadata to enable everyone to understand it. Details of which can be read in this <a href="https://services.blog.gov.uk/2022/12/14/how-content-design-helped-to-frame-a-new-service-around-nhs-data-standards/">2022 blog on the use of content design to build the Standards Directory.</a>

## Who manages this service

This service is managed by NHS England and Improvement working closely with organisations involved in standards development. You can contact the standards directory team by emailing <a href="mailto:england.interop.standards@nhs.net">england.interop.standards@nhs.net</a>.

About this service

## What we mean by standards
This service contains standards, which we group into 4 categories:

*   **A Collection** is a systematic gathering of a specified selection of data or information for a particular stated purpose from existing records held within health and care systems and electronic devices.

[Browse collections](/search-results?standard_category=Collections).

*   **An Extraction** is a type of collection that is pulled from an operational system by the data controller and transmitted to the receiver without additional processing or transcription by the sender..

[Browse extractions](/search-results?standard_category=Extractions).

*   **Technical standards and specifications** specify how to make information available technically including how the data is structured and transported

[Browse technical standards and specifications](/search-results?standard_category=Technical+standards+and+specifications).

* **Information standards** are agreed ways of doing something, written down as a set of precise criteria so they can be used as rules, guidelines, or definitions.

[Browse information standards](/search-results?standard_category=Information+standards).

Not every standard that exists is listed in this service. You can [find out which standards are included](/about-this-service#what-standards-are-included). 

## Benefits of using standards
There are many benefits to using standards including:

* it’s more efficient to reuse existing approaches to recording or exchanging data than creating new ones
* it promotes quality by ensuring all care settings are aligned to standards that have been approved by qualified bodies
* it makes it easier to analyse data at the national level and see trends or problems if the data has all been standardised 
* it is essential to achieving interoperability, which would allow IT systems across the country to share data. An example of this is hospitals being able to update GP records directly using their own systems instead of sending emails

## Report a gap in standards
Work is underway to publish a process for people developing new standards. 

In the meantime, please notify us of plans to create new standards by emailing england.interop.standards@nhs.net. Local standards that apply at the national level may be uplifted for national use.

About standards

Standards which have not yet been published will appear on the roadmap page

List any related standards e.g. if the standard forms part of a broader package that users may wish to implement together

Any standards or services (e.g. SNOMED CT or the Patient Administration System) that must be implemented in order for this standard to work

e.g. Association of Directors of Adult Social Services
