The 8 Caldicott Principles Explained with Examples
If you work in the healthcare sector, it’s important that you gain an understanding of the Caldicott Principles and their purpose in protecting patient-identifiable data.
To help you understand how to protect patient confidentiality, our expert team of subject leaders have developed a comprehensive catalogue of online healthcare training courses.
Otherwise, keep reading to get to know how many Caldicott Principles there are and what they all mean.
What Are the Caldicott Principles?
The Caldicott Principles were developed in 1997 in order to provide clear guidance on the proper handling of patient-identifying data. The framework consists of key principles that healthcare professionals must follow when working with patient information.
These principles form a vital decision-making framework for sharing data, for instance between healthcare providers or organisations.
This recognises that sharing patient information is often necessary for providing effective patient care and that in these situations healthcare professionals have a duty to maintain patient confidentiality and adhere to data protection laws such as GDPR & the Data Protection Act.
What Is Patient-Identifiable Information?
This vital patient data refers to anything that directly or indirectly reveals the identity of the individual patient.
This includes:
- The patient's full name
- Date of birth
- Home address
- NHS number
- Visual or audio material of the client i.e. photos, videos or recordings
- Any other identifying information - this could also refer to test results or health conditions which could lead to the identification of the individual
Any of this data could potentially compromise the patient’s right to patient confidentiality if mishandled.
Why Were They Introduced?
The Caldicott Principles were introduced due to concern about how patient information was being handled in the NHS. The increasing use of computer systems and electronic record keeping in the NHS came about at the same time as rising concern about sharing information for non-clinical purposes such as research or administration.
This all raised big questions about whether patient data was being handled ethically and appropriately.
The Caldicott Principles set out clear standards for what, when and how information could be shared, protecting patient confidentiality while ensuring necessary information sharing for quality care.
How Many Caldicott Principles Are There?
There are currently 8 Caldicott Principles. The most recent principle was added in December 2020 to reflect the growing importance of patient data rights and increased transparency.
The 8 Caldicott Principles at a glance:
Principle | Key Point |
1. Justify the purpose(s) for using confidential information | All use of patient data requires clear justification and documented purpose |
2. Use confidential information only when it is necessary | Only use patient-identifiable data when essential |
3. Use the minimum necessary confidential information | Use as little information as possible for the task |
4. Access to confidential information should be on a strict need-to-know basis | Only those who need access should have it |
5. Everyone with access to confidential information should be aware of their responsibilities | All staff must understand and actively maintain information governance duties |
6. Comply with the law | Comply with data protection legislation and NHS governance frameworks |
7. The duty to share information for individual care is as important as the duty to protect patient confidentiality | Understand that sharing data can be as important as confidentiality for patient care |
8. Inform patients and service users about how their confidential information is used | Ensure transparency with patients about all data sharing |
The 8 Caldicott Principles Explained with Examples
The Caldicott Principles help healthcare workers understand exactly when, how and why they can share patient information. Let's take a look at each principle in detail along with examples to illustrate them.
Principle 1: Justify the purpose(s) for using confidential information
Explanation: Whenever you want to use or share patient information, you must have a clear and valid reason. It's not enough to share information simply because you can - there has to be a specific purpose.
Example: A nurse needs to share a patient's medical record with a consultant for a referral. This has a clear purpose in enabling necessary treatment.
Principle 2: Use confidential information only when it is necessary
Explanation: Having access to patient information doesn't mean you should use it. Only use identifiable information when it's essential for the task at hand.
Example: For monthly departmental reports on appointment attendance rates, anonymised statistics should be used rather than lists of individual patient details.
Principle 3: Use the minimum necessary confidential information
Explanation: When you do need to use patient information, use as little as possible to get the job done. Ask yourself what the minimum you need to share is to achieve this purpose.
Example: If you’re referring a patient to a podiatrist, only share their foot-related health issues and relevant medications, not their entire mental health history or unrelated conditions.
Principle 4: Access to confidential information should be on a strict need-to-know basis
Explanation: Access to patient information must be strictly limited to those who require it for direct care or authorised duties. This means limiting access to those who genuinely need it for their work.
Example: A physiotherapist working in outpatients can access records for their own patients, but not records of patients in other departments who aren't under their care.
Principle 5: Everyone with access to confidential information should be aware of their responsibilities
Explanation: All staff must understand and actively maintain their information governance responsibilities. This means knowing what they can and cannot do with the information.
Example: An administrator processing clinic letters knows that they must never discuss confidential patient details in public areas like corridors or the canteen.
Principle 6: Comply with the law
Explanation: All handling of patient information must comply with data protection legislation and NHS governance frameworks. This means understanding and following both the law and your organisation's policies.
Example: Staff must follow their organisation's cyber security policies by only using encrypted, secure NHS systems to share patient information and never using personal email.
Principle 7: The duty to share information for individual care is as important as the duty to protect patient confidentiality
Explanation: Whilst protecting confidentiality is crucial, sometimes sharing information is just as vital for proper patient care. Concerns about confidentiality shouldn’t prevent necessary information sharing.
Example: In certain specific safeguarding situations, healthcare staff have a legal duty to share concerns with relevant teams, even without patient consent. However, they should explain this to the patient where it is safe to do so.
Principle 8: Inform patients and service users about how their confidential information is used
Explanation: Patients must be informed about how their information is used, ensuring transparency in all data sharing. Be open and clear about how you handle their data and why.
Example: When registering for NHS services staff should always explain how patient information is shared for care and discuss the patient's sharing preferences.
What is a Caldicott Guardian?
After explaining the 8 principles, it's important to understand who oversees these principles in practice.
Every NHS organisation must have a Caldicott Guardian - a senior person responsible for protecting patient information. They ensure their organisation follows the Caldicott Principles and fulfils its legal obligations to patient confidentiality.
