Caldicott Principles – A Complete Guide

Caldicott Principles

What are the Caldicott Principles?

Developed in 1997, the Caldicott Principles provide a framework to help health organisations ensure proper handling of patient-identifying information. Following the principles helps organisations make correct decisions when processing this information and works to protect patient confidentiality in a variety of situations.

Organisations and those working within them must be able to determine when sharing confidential patient information could breach data protection laws.

When potential conflicts or difficult decisions arise, the Caldicott Principles can aid with decision-making. The principles also cover secure transfer methods of sensitive patient information to other agencies such as the police, social services, the education system and the judicial system.

Where Did the Principles Come From?

The Caldicott Principles were developed after a review of NHS patient data handling. At the time, the rise of technology and data collection caused concern that patient-identifying data could be too easily shared and that privacy could be too easily breached.

Chaired by Dame Fiona Caldicott, the review led to the identification of best practices concerning data security. The original six principles set out in 1997 have been expanded twice (in 2013 and 2020), and now the list includes eight Caldicott Principles.

The principles are built on the idea that patients should have as much control as possible over their personal information and that patients should be assured that the information held by health and social care organisations is safe from unnecessary disclosure. Patients should also have complete confidence in the systems that hold this information.

This online course helps employees understand compliance requirements and reduces the risk of data breaches in the workplace.

What is Patient-Identifiable Information?

Patient-identifiable information includes the patient’s:

  • Full name
  • Home address and postcode
  • Date of birth
  • NHS number
  • Image, including photos, video or audio recordings

Health conditions or results that may be used directly or indirectly to identify the patient are also considered identifiable information. For example, this could include rare diseases, specific drug treatments or results of statistical analyses using small sample sizes.

8 Caldicott Principles

The 8 Caldicott Principles

There are eight principles for healthcare professionals to properly handle patient information.

Principle 1: Justify the Purpose for Using Confidential Information

Each time confidential information is used or transferred, the purpose of doing so must be clearly defined, examined and documented. An appointed Caldicott Guardian should review each action, use or transfer to ensure that patient privacy is protected as much as possible. If the same patient information is being shared multiple times, the Guardian must examine each instance for propriety.

Principle 2: Use Confidential Information Only When Necessary

Confidential information should be limited to purposes that require it. In other words, confidential information should be left out whenever possible. If a specified purpose requires the use or sharing of confidential information, it must be carefully limited to the scope of the purpose. The need to identify individuals should be weighed at each step of the process, and alternatives should be used whenever possible.

Principle 3: Use the Minimum Necessary Personal Confidential Data

When the use of confidential information is unavoidable, the amount of information used should be kept to an absolute minimum. Only the information pertaining to a task should be made available. Tasks and purposes requiring confidential information should be completed with minimal intrusion into personal matters or information.

Principle 4: Access to Confidential Information Must Be on a Strict Need-to-Know Basis

Only people who truly need it should be given access to confidential information and access should be limited to the items they need to see. Access controls or split information flows are helpful for this.

Principle 5: Everyone with Access to Personal Confidential Data Must Be Aware of Their Responsibilities

Personnel who work with, handle, organise, receive or transmit confidential data must fully understand their duty to protect patient and service user confidentiality. These employees should be given special training, and additional reminders should be built into the systems they use.

Principle 6: Comply with the Law

Each and every use of confidential information must be lawful. Each person handling such information is personally responsible for ensuring that the legal integrity of data sharing and storage remains secure.

Principle 7: The Duty to Share Information Can Be as Important as the Duty to Protect Patient Confidentiality

If a health or social care worker finds that sharing information is in the best interest of the patient, they should be able to do so with confidence, provided that they follow the other principles. These decisions to share should be supported by their employer, regulator, and professional bodies or associations.

Circumstances in which sharing may meet such criteria include:

  • Patients are transferred from one hospital to another for further treatment
  • Patients, or others they’re connected to, may be at risk of harm
  • Patients pose a risk to themselves or others
  • A crime may be prevented by sharing the information
  • A patient has died, and their relatives need to be identified
  • Information has been requested by a legal authority or court order

Principle 8: Inform Patients and Service Users How Their Confidential Information is Used

Patients and service users should have clear expectations about how and why their confidential information is shared and what choices are available to them when it happens. Organisations should follow proper procedures closely when handling confidential information. At a minimum, organisations should provide patients with accessible, relevant, and appropriate information about the process. Some patients may need to participate more in the process, depending on the case.

How many Caldicott Principles are there

What is a Caldicott Guardian?

The review recommended that each NHS organisation should appoint a Caldicott Guardian. This is the individual responsible for safeguarding patient information. They must also make sure that good practices are followed and are implemented.

A Caldicott Guardian must also manage confidential information in accordance with:

  • UK General Data Protection Regulation (GDPR)
  • The Data Protection Act
  • The Human Rights Act
  • The NHS Act
  • The Freedom of Information Act
  • The Computer Misuse Act
  • NHS Information Governance
  • The NHS Constitution

An appointed Caldicott Guardian should be:

  • On the management board or a member of the senior management team.
  • A senior health or social care professional.
  • Responsible for promoting clinical governance within the organisation.

What Organisations Should Have Caldicott Guardians?

Initially, Caldicott Guardians were needed in NHS organisations and local authorities that provide social services.

However, the current guidance widens the type and number of organisations that are expected to have a Caldicott Guardian. Organisations that should have a Caldicott Guardian now also include:

  • Public bodies involved in health services, adult social care, or adult carer support in England.
  • Other organisations that provide similar services under public contracts and process confidential information about service users.

How Can You Apply the Caldicott Principles?

The Caldicott Principles must be followed by health and social care organisations. They provide guidance on how best to ensure that patient data is kept confidential and can also prevent damaging data breaches.

When applying the principles, the first thing to do is to ensure that everyone involved understands that the Caldicott Principles exist to protect patients. While the principles heavily emphasise caution and restraint when handling patient data, it’s equally important to remember that sharing data is sometimes more beneficial to the patient than withholding it (principle number seven).

Organisations and staff should regularly review their policies and procedures, keeping in mind the Caldicott Principles. Correct use of the principles should maximise patient privacy while also promoting patient care.

Conclusion

The Caldicott Principles play a vital role in health and social care by safeguarding patient information. When applied correctly, they help prevent data breaches, protecting both individuals and organisations.

Understanding data protection laws, including GDPR, is just as important. GDPR sets the legal framework for handling personal data across all industries, ensuring compliance and reducing the risk of fines or reputational damage.
